    OBJECTIVE: To assess the efficacy of the FIGO 2018 classification system for nodal-specific classifications for early-stage cervical cancer; specifically, to examine the impact of nodal metastasis on survival and the effect of postoperative treatments, according to histological subtypes. METHODS: This society-based retrospective observational study in Japan examined 16,539 women with the 2009 FIGO stage IB1 cervical cancer who underwent primary surgical treatment from 2004 to 2015. Associations of cause-specific survival (CSS) with nodal metastasis and postoperative adjuvant therapy were examined according to histology type (squamous cell carcinoma [SCC], n=10,315; and non-SCC, n=6,224). RESULTS: The nodal metastasis rate for SCC was higher than that for non-SCC (10.7% vs. 8.3%, p<0.001). In multivariable analysis, the impact of nodal metastasis on CSS was greater for non-SCC tumors (adjusted-hazard ratio [HR], 3.11; 95% confidence interval [CI], 2.40-4.02) than for SCC tumors (adjusted-HR, 2.20; 95% CI, 1.70-2.84; p<0.001). Propensity score matching analysis showed significantly lower CSS rates for women with pelvic nodal metastasis from non-SCC tumors than from SCC tumors (5-year CSS rate, 75.4% vs. 90.3%, p<0.001). The CSS rates for women with nodal metastasis in SCC histology were similar between the postoperative concurrent chemoradiotherapy/radiotherapy and chemotherapy groups (89.2% vs. 86.1%, p=0.42), whereas those in non-SCC histology who received postoperative chemotherapy improved the CSS (74.1% vs. 67.7%, p=0.043). CONCLUSION: The node-specific staging system in the 2018 FIGO cervical cancer classification is applicable to both non-SCC tumors and SCC tumors; however, the prognostic significance of nodal metastases and efficacy of postoperative therapies vary according to histology.

    OBJECTIVE: The study compared the treatment outcomes of surgery versus radiotherapy, including concurrent chemoradiotherapy, in stage Ib2-IIb cervical adenocarcinoma patients in Japan. METHODS: Of 57,470 patients diagnosed with stage I-IV cervical cancer from January 2001-December 2011, 1,932 patients with stage Ib2-IIb cervical adenocarcinoma were initially treated by surgery or radiotherapy. The primary endpoint was 5-year overall survival (OS) in all and 614 propensity score-matched (PSM) patients (307 per group). We compared OS and prognosis factors based on age, primary stage, and treatment arm. RESULTS: In Japan, >80% (n=1,573) of stage Ib2-IIb cervical adenocarcinoma patients underwent surgery. The 5-year OS of surgery vs. radiotherapy groups were 82.1% (n=704) vs. 79.7% (n=59) (hazard ratio [HR]=1.494; 95% confidence interval [CI]=0.826-2.702; p=0.181) for stage Ib2, 76.6% (n=239) vs. 66.7% (n=54) (HR=1.679; 95% CI=0.986-2.858; p=0.053) for stage IIa, and 71.1% (n=630) vs. 58.9% (n=246) (HR=1.711; 95% CI=1.341-2.184; p<0.001) for stage IIb. In 614 PSM patients balanced for age and carcinoma stage Ib2-IIb, the 5-year OS of surgery vs. radiation groups was 73.0% (n=307) vs. 65.5% (n=307) (HR=1.394; 95% CI=1.044-1.860; p=0.023). In multivariable analysis, age (HR=1.293; 95% CI=1.045-1.601; p=0.018), treatment arm, radiotherapy (HR=1.556; 95% CI=1.253-1.933; p<0.001), and stage IIb (HR=1.783; 95% CI=1.443-2.203; p=0.018) were independent prognosis factors for 5-year OS in stage Ib2-IIb adenocarcinoma patients. CONCLUSION: Age (>65 years), treatment arm (radiotherapy), and stage IIb significantly affect OS in cervical adenocarcinoma patients. Surgery may be considered for <65-year-old patients with stage IIb adenocarcinoma.

    OBJECTIVES: The aim of this study was to elucidate the clinicopathological features of ovarian granulosa cell tumors (GCTs) and to identify the prognostic factors. METHODS: The Japanese Society of Gynecologic Oncology (JSGO) conducted an observational retrospective cohort study of women with GCTs enrolled in the Gynecological Tumor Registry of the Japan Society of Obstetrics and Gynecology (JSOG) between 2002 and 2015. Clinicopathological features, including lymph node metastasis, were evaluated. In addition, we performed a prognostic analysis of patients between 2002 and 2011 for whom survival data were available. Kaplan-Meier and multivariate Cox proportional hazards analyses were performed. RESULTS: We identified 1426 patients with GCTs. Of the 222 patients who underwent lymph node dissection, 10 (4.5%) had lymph node metastasis. The incidence of lymph node metastasis in patients with pT1, pT2, and pT3 was 2.1%, 13.3%, and 26.7%, respectively (p < 0.001). Prognostic analysis was performed on 674 patients. In the multivariate Cox regression analysis, residual disease after initial surgery (hazard ratio (HR) = 10.39, 95% confidence interval (CI) = 3.15-34.29) and lymph node metastasis (HR = 5.58, 95% CI = 1.62-19.19) were independent risk factors for cancer-specific survival. CONCLUSIONS: In the initial surgery for GCTs, lymph node dissection can be omitted if the operative finding is pT1. In cases of pT2 or higher, lymph node dissection should be considered. Debulking is critical for achieving no gross residual tumor at the end of the surgery.

    OBJECTIVE: To clarify the role of radiotherapy for endometrial cancer. METHODS: Data were analyzed for 39 247 patients with endometrial cancer registered with the Gynecologic Cancer Registry of the Japan Society of Obstetrics and Gynecology from 2004 to 2011. RESULTS: The rates of 5-year overall survival (5y-OS) in the radiotherapy and surgery groups were 53.6% and 94.5% in stage I or II, and 15.5% and 67.5% in stage III or IV, respectively. The prognosis in the radiotherapy group was significantly poorer than that in the surgery group. In multivariate analysis, age, advanced stage, histological type, risk of recurrence, and initial radiotherapy were independent prognostic factors. The rates of 5y-OS with no adjuvant therapy, adjuvant chemotherapy, and adjuvant radiotherapy were 95.3%, 92.9%, and 87.1% for stage I or II, respectively, with significant differences among all groups (P < 0.001), and 60.0%, 70.4%, and 55.5% for stage III or IV, respectively, with significant differences of adjuvant chemotherapy with no adjuvant therapy (P < 0.001) and with adjuvant radiotherapy (P < 0.001). In multivariate analysis, age, advanced stage, histological type, lymphadenectomy, and adjuvant radiotherapy were independent prognostic factors. CONCLUSION: Patients treated with radiotherapy had a significantly poorer prognosis and the appropriate indication of radiotherapy for endometrial cancer requires further study.

    OBJECTIVE: To determine the association between cervical polyps in early pregnancy and late abortion and spontaneous preterm birth (SPTB). We also aimed to explore the relationship between cervical polyps and cervical insufficiency in the second trimester. METHODS: We conducted a retrospective cohort study of 2941 singleton pregnant women between January 2010 and December 2015. The frequency of late abortion and SPTB (before 28, 34, or 37 weeks of pregnancy) was compared between the two groups of 142 (4.8%) patients who had cervical polyps early in the pregnancy (P group) and 2799 who did not (non-P group). Multivariate analysis was performed to identify risk factors for late abortion and SPTB. RESULTS: The incidence of late abortion and SPTB was significantly higher in the P group than in the non-P group. Cervical polyps in early pregnancy were selected as independent risk factors for late abortion and SPTB before 28, 34, or 37 weeks of pregnancy. The P group had a significantly higher rate of cases requiring therapeutic cervical cerclage than the non-P group. CONCLUSION: Cervical polyps in early pregnancy are risk factors for late abortion and SPTB. They are also associated with the occurrence of cervical insufficiency.

    OBJECTIVE: Regional lymph node (LN) dissection is a standard surgical procedure for endometrial cancer, but there is currently no clear consensus on its therapeutic significance. We aimed to determine the impact of regional LN dissection on the outcome of endometrial cancer. METHODS: Study subjects comprised 36,813 patients who were registered in the gynecological tumor registry of the Japan Society of Obstetrics and Gynecology, had undergone initial surgery for endometrial cancer between 2004 and 2011, and whose clinicopathological factors and prognosis were appropriate for our investigation. The following clinicopathological factors were obtained from the registry: age, surgical stage classification, Union for International Cancer Control tumor, node, metastasis classification, histological type, histological differentiation, presence or absence of LN dissection, and postoperative treatment. We retrospectively analyzed the clinicopathological factors and therapeutic outcomes for patients with endometrial cancer. RESULTS: Analysis of all subjects showed that the group that underwent LN dissection had a significantly better overall survival than the group that did not undergo dissection. Analysis based on stage showed similar results across groups, except for stage Ia. Analysis based on stage and histological type showed similar results across groups, except for stage Ia endometrial carcinoma G1 or Ia G2. Multivariate analysis of prognostic factors indicated that LN dissection is an independent prognostic factor and that it has a greater impact on prognosis than adjuvant chemotherapy. CONCLUSION: Despite the limitations of a retrospective study with some biases, the results suggest that LN dissection in endometrial cancer has a prognostic effect.

    (1) Background: This study examined the use of a two-tier system in grouping cervical adenocarcinoma for survival discrimination. (2) Methods: A nationwide retrospective observational cohort study was conducted using the Japan Society of Gynecologic Oncology tumor registry database from 2001 to 2015 (n = 86,754). Adenocarcinoma subtypes were grouped as type 1 (endocervical usual type and endometrioid) or type 2 (serous, clear, mucinous, and not otherwise specified), based on their relative survival compared with that of squamous tumors. (3) Results: The majority of the adenocarcinoma cases were type 1 (n = 10,121) versus type 2 tumors (n = 5157). Type 2 tumors were more likely to be old and have stage IV disease than those with squamous tumors. The number of type 2 tumors increased from 2001 to 2014 (106.1% relative increase, p < 0.001). Type 2 tumors had disproportionally poorer survival compared to other types (5-year survival rates: 68.9% for type 2, 75.4% for type 1, and 78.0% for squamous; p < 0.001). On multivariate analysis, type 2 tumors remained an independent prognostic factor associated with decreased survival compared with squamous (adjusted hazard ratio 2.00, 95% CI 1.84-2.15, p < 0.001). (4) Conclusion: The survival of cervical adenocarcinoma varies largely across the histological subtypes, and the proposed two-tier grouping may be useful for survival discrimination.

    OBJECTIVE: To examine the incidence and prognostic effects of intraoperative capsule rupture and to assess the effectiveness of postoperative chemotherapy for intraoperative tumor rupture in apparent stage I epithelial ovarian cancer. METHODS: This is a society-based retrospective observational study in Japan that examined 15,163 women with stage IA-IC1 epithelial ovarian cancer who underwent primary surgical treatment between 2002 and 2015. Associations between intraoperative capsule rupture and cause-specific survival, and between postoperative chemotherapy and cause-specific survival among intraoperatively ruptured cases were examined by histology type (clear cell n=6,107, endometrioid n=3,910, mucinous n=3,382, and serous n=1,764). RESULTS: Clear cell histology had the highest risk of intraoperative capsule rupture (57.3%), followed by endometrioid (48.8%), serous (41.8%), and mucinous (32.0%) histologies (P<.001). On multivariable analysis, clear cell type exhibited the largest effect of intraoperative capsule rupture on cause-specific survival (adjusted hazard ratio [HR] 1.99, 95% CI 1.45-2.75), followed by serous (adjusted HR, 1.61, 95% CI 0.84-3.11), mucinous (adjusted HR 1.28, 95% CI 0.79-2.09), and endometrioid (adjusted HR, 1.14, 95% CI 0.64-2.01) tumors. Postoperative chemotherapy for intraoperatively ruptured cases did not improve cause-specific survival in any histologic types in multivariable analysis: clear cell, adjusted HR 0.86, 95% CI 0.56-1.31; serous, adjusted HR 1.08, 95% CI 0.42-2.74; mucinous, adjusted HR 1.11, 95% CI 0.55-2.27; and endometrioid, adjusted HR 2.81, 95% CI 0.85-9.30 (all, P>.05). In the cohort-level analysis of ruptured cases (n=7,227), postoperative chemotherapy use has significantly decreased in mucinous (16.3% relative decrease), endometrioid (13.1% relative decrease), and clear cell (9.3% relative decrease) (all, P<.05); but, the cohort-level 5-year cause-specific survival rate did not change over time (all, P>.05). CONCLUSION: Among apparent stage I epithelial ovarian cancer, the clear cell type possesses a disproportionally high risk of capsule rupture during adnexectomy and is associated with the most adverse effect on survival. A decrease in the use of postoperative chemotherapy for intraoperatively ruptured cases in Japan is likely the result of increasing awareness of the absence of survival benefits.

    The aim of this prospective cohort study was to evaluate clinical factors associated with pregnancy outcomes in women with recurrent pregnancy loss (RPL). Women with a history of two or more pregnancy losses underwent workups for clinical factors of RPL and their pregnancies were followed-up with informed consent. Two hundred eleven (81.5%) of 259 women with RPL became pregnant. The multivariable analyses demonstrated that age (p < .01, OR 0.9, 95%CI 0.97-0.83), uterine abnormality (p < .05, OR 0.3, 95%CI 0.11-0.8), and protein C (PC) deficiency (p < .01, OR 0.14, 95%CI 0.03-0.6) were independent factors for becoming pregnancy in women with RPL. The number of previous pregnancy loss (p < .01, OR 0.57, 95%CI 0.43-0.75) and natural killer (NK) cell activity ≥33% (p < .01, OR 0.31, 95%CI 0.13-0.73) were independent factors for live birth in the subsequent pregnancy. Advanced age, the presence of uterine abnormality, and PC deficiency were risk factors for reduced pregnancy rate in women with RPL. Increased number of previous pregnancy loss and high NK cell activity were risk factors for miscarriage in the subsequent pregnancy. These results involve important information and are helpful for clinical practitioners.

    Primary infection with Toxoplasma gondii (T. gondii) during pregnancy may cause congenital infection of the infant. This study evaluated whether screening using IgG avidity and multiplex-nested polymerase chain reaction (PCR) methods was effective for detecting a high-risk pregnancy for congenital T. gondii infection. In a prospective cohort study serum T. gondii IgG avidity was measured in 469 pregnant women who had a positive test for T. gondii antibody plus a positive or equivocal test for IgM. Multiplex-nested PCR for T. gondii DNA on amniotic fluid, maternal blood, and neonatal blood was performed with informed consent. Low (<30%), borderline (30-35%), and high (>35%) IgG avidity indices were found in 104 (22.2%), 30 (6.4%), and 305 (71.4%), respectively. A total of 12 cases had a positive PCR test for amniotic fluids of the prenatal amniocentesis or at birth, or neonatal blood. Seven of the 12 cases were diagnosed as having congenital T. gondii infection, and they had low IgG avidity indices. Congenital T. gondii infection screening using of IgG avidity and multiplex-nested PCR methods for pregnant women with a positive test for T. gondii antibody plus a positive or equivocal test for T. gondii IgM was useful for detecting a high-risk pregnancy and diagnosing congenital T. gondii infection.

    OBJECTIVE: To examine the trends of epithelial ovarian cancer histologic subtypes in Japan. METHODS: A nationwide retrospective registry study was performed between 2002 and 2015 (Japan cohort, n = 48,640). Trends were also examined in The Surveillance, Epidemiology, and End Results Program (US cohort, n = 49,936). Time-specific proportional changes of four major histological subtypes (serous, clear cell, endometrioid, and mucinous) were examined. RESULTS: The Japan cohort had more stage I disease (44.1% versus 24.9%) and less stage IV disease (10.0% versus 23.1%) than the US cohort (P < 0.001). The Japan cohort had more non-serous histology, particularly clear cell carcinoma (26.9% versus 8.4%), than the US cohort (P < 0.001). In the Japan cohort, proportion of clear cell carcinoma increased significantly from 23.4% to 29.1% between 2002 and 2010 (P < 0.001). Among stage I disease, clear cell carcinoma increased significantly in the Japan cohort from 32.9% to 40.3% between 2002 and 2015 (P < 0.001), whereas mucinous carcinoma increased significantly in the US cohort from 15.0% to 24.8% (P = 0.01). In 2015, clear cell carcinoma was most common among women aged <50 years from the Japan cohort (30.2%) versus serous carcinoma in the US cohort (50.8%). In the Japan cohort, the peak age was 75 years for serous, 57 for clear cell, and 45 for endometrioid carcinoma (P < 0.001). Mucinous carcinoma decreased until 43 years and increased again after age 73 years (P < 0.001). CONCLUSION: Characteristics of epithelial ovarian cancer in Japan are largely different compared to the US. In Japan, clear cell carcinoma has increased significantly in recent years to account for nearly 30% of epithelial ovarian cancer.

    Antibodies against fetal platelet alloantigens in maternal blood cause neonatal alloimmune thrombocytopenia (NAIT). We encountered four newborns with NAIT from three women. A woman carried anti-human platelet antigen (HPA)-1a antibody, and vaginally delivered a newborn who had subarachnoid hemorrhage and platelet transfusions. She delivered the second newborn by a cesarean section who had no symptom. The second woman carried anti-human leukocyte antigen-A2 antibody and vaginally delivered a newborn who had no symptom. The third woman with a history of recurrent pregnancy losses carried anti-HPA-4b antibody, and delivered a newborn by a cesarean section who received platelet transfusions and immunoglobulin infusions. Antiplatelet antibody screening may be helpful in women who have a history of blood transfusion, or previous neonates with thrombocytopenia or intracranial hemorrhage.

    The Japan Society of Gynecologic Oncology (JSGO) Guidelines 2017 for the Treatment of Uterine Cervical Cancer are for the purpose of providing standard treatment strategies for cervical cancer, indicating treatment methods currently considered appropriate for cervical cancer, minimizing variances in treatment methods among institutions, improving the safety of treatment and prognosis of diseases, reducing the economic and psychosomatic burden of patients by promoting performance of appropriate treatment, and enhancing mutual understanding between patients and healthcare professionals. The guidelines were prepared through consensus of the JSGO Guideline Committee, based on careful review of evidence gathered through the literature searches and in view of the medical health insurance system and actual clinical practice situations in Japan. The guidelines comprise eight chapters and five algorithms. The main features of the 2017 revision are as follows: (1) evidence was collected using a search formula and with cooperation of the Japan Library Association. The bibliographical search formula was placed at the end of the book; (2) regarding clinical questions (CQs) where evidence or clinical inspection in Japan was lacking, opinions of the Guidelines Committee were described as "proposals for future directions"; (3) cervical intraepithelial neoplasia (CIN) 3 and adenocarcinoma in situ (AIS) were treated as a cervical precancerous lesion; (4) the CQs of endoscopic surgery, radical trachelectomy, and sentinel node biopsy were newly added in Chapter 3, "primary treatment for stage IB-II cervical cancer"; and (5) the CQ about hormone replacement therapy after cancer treatment was newly established. Each recommendation is accompanied by a classification of recommendation categories based on the consensus reached by the Guideline Committee members. Here, we present the English version of the JSGO Guidelines 2017 for the Treatment of Uterine Cervical Cancer.

    The aim of this nested case-control study was to evaluate clinical factors associated with the occurrence of congenital cytomegalovirus (CMV) infection in pregnant women with non-primary CMV infection. In a cohort study of CMV screening for 2193 pregnant women and their newborns, seven newborns with congenital CMV infection were identified among 1287 pregnant women with non-primary CMV infection that was defined as negative IgM and positive IgG with IgG avidity index >45%. In the 1287 women with non-primary CMV infection, clinical findings and complications were compared between pregnancies with and without congenital CMV infection. Clinical factors associated with the occurrence of congenital CMV infection were evaluated. The birth weight of newborns with congenital CMV infection was less than that of newborns without congenital infection (p < 0.05). Univariate logistic regression analyses demonstrated that threatened premature delivery (OR 10.6, 95%CI 2.0-55.0; p < 0.01) and multiple pregnancy (OR 7.1, 95%CI 1.4-37.4; p < 0.05) were associated with congenital infection. Multivariable logistic regression analyses demonstrated that threatened premature delivery (OR 8.4, 95%CI 1.5-48.1; p < 0.05) was a single risk factor for congenital CMV infection in pregnant women with non-primary CMV infection. This study revealed for the first time that threatened premature delivery was associated with the occurrence of congenital CMV infection in pregnant women with non-primary CMV infection, the pathophysiology of which may be closely associated with CMV reactivation during pregnancy.

    We aim to clarify the incidence of deep venous thrombosis (DVT) before treatment in women with ovarian cancer and identify risk factors for DVT.In this prospective study, 110 women underwent venous ultrasonography before cancer treatment and D-dimer levels were measured. We investigated factors predicting DVT by logistic regression.DVT was detected in 25 of 110 women (22.7%) and pulmonary thromboembolism was coexisted in 2 women (1.8%). A total of 21 women (84.4%) with DVT were asymptomatic. D-dimer levels in women with DVT (median, 10.9; range, <0.5-98.2 μg/mL) were significantly higher than those in women without DVT (2.0; <0.5-60.8 μg/mL; P < .01). When 10.9 μg/mL was used as a cutoff value for D-dimer levels to predict DVT, specificity, sensitivity, and positive and negative predictive values were 92.9%, 52.0%, 68.4%, and 86.8%, respectively. The multivariate analysis demonstrated that D-dimer level (odds ratio [OR], 19.7; 95% confidence interval [CI], 5.89-76.76) and clear cell histology (OR, 7.1; 95% CI, 2.12-25.67) were independent factors predicting DVT.Asymptomatic DVT occurred with great frequency before treatment in patients with ovarian cancer. High D-dimer level and clear cell pathology is associated with a higher DVT risk.

    BACKGROUND: Both twin pregnancies with complete hydatidiform mole and coexisting normal fetus (CHMCF) and partial hydatidiform mole can be found in association with a live fetus and a placenta displaying a molar degeneration. Two cases of CHMCF using magnetic resonance imaging (MRI) for a diagnosis are reported. CASE: In the first, CHMCF was suspected at 12 weeks of gestation. At 18 weeks of gestation, the existence of molar placenta and a sac separating from fetus and normal placenta was clearly depicted on MRI. At 19 weeks of gestations, she had termination of pregnancy because of a development of gestational trophoblastic neoplasia (GTN) and started chemotherapy. In the second case, CHMCF was suspected at 14 weeks of gestation. MRI demonstrated the existence of molar placenta and a sac separating from fetus and normal placenta. She chose induced abortion and there was no evidence of GTN during the 1 year-follow up period. Pathological examination in both cases was consistent with a complete hydration mole and a coexisting normal female fetus. CONCLUSION: MRI was useful for an accurate diagnosis for CHMCF.

    This study aimed to compare dosimetric parameters between non-optimized and optimized treatment planning (NOP and OP, respectively) of magnetic resonance imaging (MRI) -based intracavitary (IC) image-guided adaptive brachytherapy (IGABT) using the central shielding (CS) technique for cervical cancer. Fifty-three patients treated with external beam radiotherapy using CS and MRI-based IGABT with the IC approach alone were evaluated. The total high-risk clinical target volume (HR-CTV) D90 was aimed at >70 Gy equivalent dose in 2 Gy fractions (EQD2). In the small HR-CTV group (≤30 cm3), the mean D90s for NOP/OP were 98.6/80.7 Gy. In the large (30.1-40 cm3) and extensive (>40 cm3) HR-CTV groups, the mean D90s were 81.9/77.5 and 71.1/73.6 Gy, respectively. The mean D2cc values for organs at risks (OARs) in OP were acceptable in all groups, despite the high bladder D2cc in the NOP. The correlation between HR-CTV at first brachytherapy (BT) and NOP D90 was stronger than that between HR-CTV at first BT and OP D90. The targeted HR-CTV D90 and dose constraints of D2cc for OARs were both achieved in 16 NOP/47 OP patients for the bladder, 39/50 for the rectum, and 47/50 for the sigmoid colon (P < 0.001, P = 0.007, and P = 0.34, respectively). For small tumors, the role of optimization was to reduce the D2cc for OARs while maintaining the targeted D90. However, optimization was of limited value for extensive tumors. Methods of optimization in IGABT with CS for cervical cancer should be standardized while considering its effectiveness and limitations.

    INTRODUCTION: Placenta previa (PP) is one of the most significant risk factors for adherent placenta (AP). The aim of this study was to evaluate the diagnostic efficacy of a novel scoring system for predicting AP in pregnant women with PP. METHODS: This prospective cohort study enrolled 175 women with PP. The placenta previa with adherent placenta score (PPAP score) is composed of 2 categories: (1) past history of cesarean section (CS), surgical abortion, and/or uterine surgery; and (2) ultrasonography and magnetic resonance imaging findings. Each category is graded as 0, 1, 2, or 4 points, yielding a total score between 0 and 24. When women with PP had PPAP score ≥8, they were considered to be at a high risk for AP and received placement of preoperative internal iliac artery occlusion balloon catheters. If they were found to have AP during CS, they underwent hysterectomy or placenta removal using advanced bipolar with balloon catheter occlusion. The predictive accuracy of PPAP score was evaluated. RESULTS: In total, 23 of the 175 women with PP were diagnosed as having AP, histopathologically or clinically. Twenty-one of 24 women with PPAP score ≥8 had AP, whereas two of 151 women with PPAP score <8 had AP. The scoring system yielded 91.3% sensitivity, 98.0% specificity, 87.5% positive predictive value, and 98.7% negative predictive value for predicting AP in women with PP. DISCUSSION: This prospective study demonstrated that PPAP scoring system may be useful for predicting AP in women with PP.

    Purpose: This study aimed to assess the efficacy of high-dose i.v. immunoglobulin (HIVIg) therapy in pregnant women with antiphospholipid syndrome (APS) secondary to systemic lupus erythematosus with a history of pregnancy failure, despite receiving low-dose aspirin plus unfractionated heparin therapy, of which condition being designated as "aspirin-heparin-resistant APS" (AHRAPS). Methods: The HIVIg therapy (20 g/d, 5 days) was performed for the pregnancies of five women with AHRAPS. Results: Five of the eight pregnancies ended in live births. The gestational ages of delivery in four of the five pregnancies were extended, compared with previous pregnancies. The HIVIg therapy was considered to be successful for these four pregnancies. Excluding one pregnancy that ended in miscarriage with an abnormal chromosome karyotype of the villi, the HIVIg therapy was considered to be successful in four (57.1%) of the seven pregnancies of the women with AHRAPS. Although all the live newborns were prematurely delivered, no adverse effect of the HIVIg therapy was observed. Conclusions: The HIVIg therapy might be beneficial as an immune modifier for pregnant women with AHRAPS. However, the precise indication of which women with AHRAPS who should receive HIVIg therapy remains unknown.

    PROBLEM: Is an abnormal increase or decrease of M1/M2 macrophages observed in the deciduae of miscarriages with normal fetal chromosome (MN)? METHODS OF STUDY: Deciduae of 18 MN and 26 miscarriages with abnormal fetal chromosome (MA) were obtained. Additionally, deciduae from 15 women whose pregnancies ended in induced abortions (IA) and endometriums at the mid-luteal phase from 19 non-pregnant women endomeriums of mid-luteal phases (EM) were obtained. Macrophages were analyzed by flow cytometry using monoclonal antibodies for CD68, HLA-DR, and CD163. RESULTS: M1 macrophages, defined as CD68+ HLA-DR+ CD163- cells, increased in MN compared with MA or IA. M2 macrophages, defined as CD68+ HLA-DR- CD163+ cells, increased in the deciduae of MA and IA compared with EM. However, this increase was not observed in the deciduae of MN. CONCLUSION: Our findings of phenotypic characters of decidual macrophages in MN provide additional evidence that M2 polarization is favorable for the maintenance of early stages of pregnancy.

    The aim of this prospective study was to determine clinical factors associated with adverse pregnancy outcomes in women with systematic lupus erythematosus (SLE). Fifty-six pregnancies from 46 women with SLE were enrolled. Risk factors for pregnancy loss, premature delivery, hypertensive disorders of pregnancy (HDP), and light-for-date neonate (LFD), were evaluated. Univariate and multivariate logistic regression analyses revealed a history of two or more pregnancy losses before 10 gestational weeks (GW) (OR 11.5, 95%CI 1.72-76.8) as a risk factor for pregnancy loss; low levels of blood complements (OR 7.55, 95%CI 1.10-51.9) and antiphospholipid syndrome (OR 26.5, 95%CI 3.17-219) as risk factors for premature delivery before 37 GW; SLEDAI score at conception (OR 1.68, 95%CI 1.05-2.68) and positive tests for two or more antiphospholipid antibodies (OR 6.89, 95%CI 1.13-41.9) as risk factors for premature delivery before 34 GW; prednisolone therapy >14mg/day (OR 7.55, 95%CI 1.10-51.9) as a risk factor for HDP; and low dose aspirin therapy (OR 0.21, 95%CI 0.05-0.97) decreased the risk for LFD neonate. These results have important implications for clinicians managing SLE complicated pregnancy.

    Background: The aim of this prospective cohort study was to evaluate the efficacy of maternal screening for congenital cytomegalovirus infection (CCI) using cytomegalovirus (CMV) immunoglobulin G (IgG) and the IgG avidity index (AI). Methods: Pregnant women underwent screening of CMV IgG and AI measurements. IgG-negative women underwent remeasurement of IgG after educational intervention. Women with an AI ≤45% received further examinations, including measurement of CMV IgM. All newborns received polymerase chain reaction analyses of the urine, and CCI was diagnosed by the detection of CMV-DNA in the urine. Primary infection was defined as an AI <35% and/or positive IgM (>1.20 index). Serum samples from women with an AI >45% were stored, and the IgM levels were measured after delivery. The efficacy of AI and IgM for CCI screening was compared. Results: A total of 1562 (71.2%) women tested positive for IgG. In this study, 10 newborns with CCI were detected. The presence of infection in 3 newborns from mothers with primary infection was predicted by screening of IgG and AI <35%. However, infection in 7 newborns from women with nonprimary infection could not be predicted by screening of CMV IgG, AI <35%, or IgM. The application of an AI <35% for CCI screening yielded 22.2% sensitivity, 95.0% specificity, 2.5% positive predictive value, and 99.5% negative predictive value and was similar to that of IgM (11.1% sensitivity, 93.2% specificity, 0.9% positive predictive value, and 92.7% negative predictive value). Conclusions: Maternal screening using CMV IgG and AI can identify pregnancies with CCI from primary infection, but overlooks a number of those from nonprimary infection.

    This study aimed to evaluate whether natural killer (NK) cell activity was associated with the etiology of recurrent miscarriage (RM), and to evaluate the predictive value of NK cell activity for outcomes of following pregnancies in women with RM. Peripheral NK cell activity was measured in 160 non-pregnant women with a history of two or more miscarriages. This activity was compared according to the etiology of RM and to pregnancy outcomes in women who became pregnant. NK cell activity in women with unexplained RM was significantly higher than that in those with known etiologies of RM. NK cell activity in women whose next pregnancies ended in miscarriage of fetuses with a normal chromosome karyotype (MN) was higher than that in those with live births (p<0.05). Women with NK cell activity ≥33% had a higher risk for MN (relative risk 3.4, 95% confidence interval 1.3-8.7). An increase in peripheral NK cell activity was associated with MN. This increase might be involved in the pathophysiology underlying RM.

    Background: Surgical meshes are widely used in incisional hernia repair. However, there are no reports of pregnancies complicated by infection of surgical meshes used for hernia repair. This is the first case report of a pregnant woman who experienced surgical site infection associated with surgical mesh used for repair of an abdominal wall incisional hernia. Case presentation: We report a case of a 41-year-old pregnant Japanese woman with surgical site infection after mesh repair of an abdominal wall incisional hernia. She was diagnosed with an abdominal wall incisional hernia at 3 months after her third cesarean section, and she underwent an operation of hernia repair with use of monofilament polypropylene mesh 7 months after the third cesarean section. However, a surgical site infection associated with surgical mesh occurred. During antibiotic treatment, she was found to be pregnant. She was referred to our hospital at 13 weeks and 2 days of gestation. The surgeons removed the infected mesh at 16 weeks and 3 days of gestation. Neither the hernia nor infection at the surgical site recurred throughout pregnancy. We planned a cesarean section using a transverse uterine fundal incision method with an upper abdominal incision. The patient delivered a 2478-g healthy female infant. Conclusions: The present report shows that removal of mesh can safely control surgical site infection during pregnancy.

    Lymphangioleiomyomatosis (LAM) is a rare disease that afflicts mostly young women. It is characterized pathologically by the appearance of interstitial collections of atypical smooth muscle cells and cyst formation in the lungs, lymph node, kidney, and so on. A case was presented that underwent radical operation with the diagnosis of endometrial cancer, in which were found LAM cells in dissected lymph node and myometrium. Case: A 40-year-old woman underwent radical operation with the diagnosis of endometrial cancer. Although the dissected pelvic and para-aortic lymph nodes did not show the metastases of cancer, immunohistochemical study revealed the LAM cells among the dissected lymph nodes. Further histological study showed the LAM cells were in the uterine myometrium as well. Physical examination excluded the diagnosis of tuberous sclerosis. Since pulmonary LAM were observed as well, the physician followed the patient. Discussion: Sporadic LAM, without a complication of tuberous sclerosis, rarely shows LAM cells systemically as in this case. Conclusions: When LAM is observed coincidentally in operated dissected lymph node, it is important to examine for tuberous sclerosis and also to follow up the fmdings in the lung.

    Background. This prospective study aimed to determine maternal clinical, laboratory, and ultrasound findings that effectively predict the occurrence of congenital cytomegalovirus (CMV) infection (CCI) in high-risk pregnant women. Methods. Three hundred CMV immunoglobulin (Ig) M-positive pregnant women were enrolled. The maternal clinical and laboratory findings, including serum CMV IgM and IgG; IgG avidity index (AI); antigenemia assay (C7-HRP); polymerase chain reaction (PCR) for the detection of CMV-DNA in the maternal serum, urine, and uterine cervical secretion; and prenatal ultrasound findings, were evaluated. To determine predictive factors for the occurrence of CCI, logistic regression analyses were performed. Results. In 22 of the 300 women, CCI was confirmed using PCR for CMV-DNA in newborn urine. Univariate analyses demonstrated that the presence of maternal flu-like symptoms, presence of ultrasound fetal abnormalities, serum titers of CMV IgM, positive results for C7-HRP, CMV IgG AI <40%, and positive PCR results in the uterine cervical secretion were statistically associated with the occurrence of CCI. Multivariable analysis revealed that the presence of ultrasound fetal abnormalities (odds ratio [OR], 31.9; 95% confidence interval [CI], 8.5-120.3; P<.001) and positive PCR results in the uterine cervical secretion (OR, 16.4; 95% CI, 5.0-54.1; P<.001) were independent predictive factors of CCI in CMV IgM-positive women. Conclusions. This is the first prospective cohort study to suggest that the presence of CMV-DNA in the maternal uterine cervical secretion and ultrasound fetal abnormalities are predictive of the occurrence of congenital CMV infection in high-risk pregnant women.

    ProblemThe aim of this prospective study was to evaluate phenotypic differences of helper T (Th), cytotoxic T (Tc), and regulatory T (Treg) cells in the deciduae of missed miscarriage with a normal chromosome karyotype of a fetus (MN) and missed miscarriage with an abnormal chromosome karyotype of a fetus (MA). Methods of studyThe decidua of 19 MN and 28 MA was obtained. Additionally, the decidua of 15 induced abortion (IA) and the endometrium of 19 non-pregnant women (EM) were obtained. IFN-(+), IL-17(+), CD25(high)Foxp3(+) cells in CD4(+) (Th) cells, and IFN-(+) cells in CD8(+) (Tc) cells were evaluated by flow cytometry. ResultsThe percentages of IFN-(+) Tc and CD4(+)CD25(high)Foxp3(+) (Treg) cells in MN were significantly increased as compared with MA and IA. The percentage of IFN-(+) Th in MN was increased as compared with IA. ConclusionActivation of IFN-(+) Tc and Treg cells in the decidua might be associated with the pathophysiology underlying MN.

    The third version of the Japan Society of Gynecologic Oncology guidelines for the treatment of uterine body neoplasms was published in 2013. The guidelines comprise nine chapters and nine algorithms. Each chapter includes a clinical question, recommendations, background, objectives, explanations, and references. This revision was intended to collect up-to-date international evidence. The highlights of this revision are to (1) newly specify costs and conflicts of interest; (2) describe the clinical significance of pelvic lymph node dissection and para-aortic lymphadenectomy, including variant histologic types; (3) describe more clearly the indications for laparoscopic surgery as the standard treatment; (4) provide guidelines for post-treatment hormone replacement therapy; (5) clearly differentiate treatment of advanced or recurrent cancer between the initial treatment and the treatment carried out after the primary operation; (6) collectively describe fertility-sparing therapy for both atypical endometrial hyperplasia and endometrioid adenocarcinoma (corresponding to G1) and newly describe relapse therapy after fertility-preserving treatment; and (7) newly describe the treatment of trophoblastic disease. Overall, the objective of these guidelines is to clearly delineate the standard of care for uterine body neoplasms in Japan with the goal of ensuring a high standard of care for all Japanese women diagnosed with uterine body neoplasms.

    Uterine leiomyosarcoma (ULMS) is an aggressive tumor associated with high rates of progression, recurrence, and mortality. Pazopanib is the only approved molecular targeted drug for advanced soft tissue sarcoma, and it has been proven to prolong progression-free survival relative to placebo. We herein report a case of ULMS with multiple lung metastases treated with pazopanib, which led to sustained disease control for 44 weeks. A 53-year-old woman was referred to our hospital due to massive uterine bleeding from a uterine corpus tumor mass. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed as emergency surgery. The final histopathological diagnosis was uterine leiomyosarcoma, and computed tomography revealed multiple lung metastases. After chemotherapy with 17 cycles of gemcitabine and docetaxel and two cycles of doxorubicin, the lung metastases had increased in size and new lesions had appeared. Pazopanib administration at 800 mg/day was started as third-line therapy. Ten weeks later, the dose of pazopanib was reduced to 600 mg/day because of hepatic impairment and hypertension. However, lung metastases of ULMS were stabilized by pazopanib administration for about 44 weeks without a decline in the patient’s quality of life. After 44 weeks of therapy, pazopanib administration was discontinued because of progressive disease and worsening of the patient’s respiratory status. Pazopanib is an oral multityrosine kinase inhibitor of vascular endothelial growth factor receptor-1,-2, and-3 platelet-derived growth factor-α and-β and c-Kit receptor. The role of pazopanib may be clinically significant in the treatment of advanced ULMS.

    This prospective study aimed to evaluate pregnancy outcome and complications in women with recurrent pregnancy loss (RPL) and protein S (PS) deficiency, who received low dose aspirin (LDA) or LDA plus heparin (LDA/H) therapies. Clinical characteristics, pregnancy outcome and complications of 38 women with two or more RPL and <60% of plasma free PS antigen were compared among three groups: antiphospholipid antibody (aPL)-negative women who received LDA (group A), aPL-negative women who received LDA/H (group B) and aPL-positive women who received LDA/H (group C). Gestational weeks (GW) at delivery in group C (median 32 GW) were earlier than 40 GW in group A and 38.5 GW in group B (p < 0.05). The birth weight in group C (median 1794 g) was less than 2855 g in group B (p < 0.05). The incidences of fetal growth restriction (37.5%), pregnancy-induced hypertension (37.5%), and preterm delivery (62.5%) in group C were higher than those (4.5%, 0%, and 4.5%, respectively) in group B (p<0.05). Women with RPL, PS deficiency, and positive aPL had high risks for adverse pregnancy outcome and complications, even when they received LDA/H therapy. Among women with RPL, PS, and negative aPL, there was no difference in these risks between LDA alone and LDA/H therapies.

    Primary Toxoplasma gondii (T. gondii) infection during pregnancy may lead to congenital toxoplasmosis. Maternal screening using T. gondii IgG avidity measurement and multiplex nested PCR was performed. The aim of this prospective cohort study was to determine a cut-off value of IgG avidity index (AI) for the prediction of the presence of T. gondii DNA in the amniotic fluid. One hundred thirty-nine women with positive or equivocal tests for IgM underwent both serum IgG avidity measurement and PCR analysis for the amniotic fluid. Nine had positive PCR results, and three of them were diagnosed as having congenital infection. A cut-off value of IgG AI was determined using receiver operating characteristic analysis. IgG AI (mean 13%) in women with positive PCR results was significantly lower than that (39%) in women with negative results. A cut-off value of <25% IgG AI yields the best results with 77.8% sensitivity and 81.5% specificity for the presence of T. gondii DNA in the amniotic fluid. None of women with IgG AI of >= 30% had a positive PCR result or congenital infection. This study firstly demonstrated that a cut-off value of 25 -30% IgG AI might be useful for the prediction of the presence of T. gondii DNA in the amniotic fluid and congenital infection.

    It was the study objective to evaluate whether low levels of plasma protein S (PS) activity, free PS, protein C (PC) activity and coagulation factor XII (FXII) during early pregnancy are related to adverse pregnancy outcomes. Peripheral blood samples were obtained at 8-14 gestational weeks (GW) from a consecutive series of 1,220 women. The levels of plasma PS activity, free PS, PC activity, and FXII were measured. Cut-off values were defined as <1st, <5th, and <10th percentiles of values obtained from 933 women whose pregnancies ended in normal deliveries without complications. PS activity of <10th percentile yielded risks of pregnancy-induced hypertension (PIN) and severe PIH, while free PS level of <5th percentile yielded a risk of pre-eclampsia. FXII level of <1st percentile yielded a risk of premature delivery (PD) at <34 GW. None was associated with PD at <37 GW, fetal growth restriction or fetal loss. A multivariate analysis demonstrated that PS activity of <10th percentile (odds ratio 5.9, 95% confidence interval 1.7-18.1) and body mass index (BMI) >= 25 kg/m(2) (4.3, 1 1.1-13.3) were independent risk factors for severe PIN. Similarly, free PS level of <5th percentile (4.4, 1.0-14.3) and BMI >= 25 kg/m(2) (4.0, 1.3-10.9) were independent risk factors for pre-eclampsia. In conclusion, women with low levels of plasma PS activity and free PS during early pregnancy might have increased risks of PIN, severe PIN or pre-eclampsia. Women with low FXII level might have an increased risk of PD at <34 GW.

    Purpose To evaluate the usefulness of metabolic parameters obtained by F-18-FDG PET/CT for preoperative stratification of high-risk and low-risk endometrial carcinomas. Methods Preoperative F-18-FDG PET/CT was performed in 56 women with endometrial cancer. Maximum standardized uptake values (SUVmax), metabolic tumour volume (MTV) and total lesion glycolysis (TLG) of primary tumours were compared with clinicopathological features of surgical specimens. Diagnostic performance in terms of differentiation of low-risk disease (endometrioid histology, histological grade 1 or 2, invasion of less than half of the myometrium, and FIGO stage I) from high-risk disease was assessed. Results MTV and TLG were significantly higher in patients with higher histological grade (p = 0.0026 and p = 0.034), larger tumour size (p = 0.002 and p = 0.0017), lymphovascular space involvement (LVSI; p = 0.012 and p = 0.0051), myometrial invasion (p = 0.027 and p = 0.031), cervical stromal invasion (p = 0.023 and p = 0.014), ovarian metastasis (p = 0.00022 and p = 0.00034), lymph node metastasis (p < 0.0001 and p < 0.0001), and higher FIGO stage (p = 0.0011 and p = 0.00048). SUVmax was significantly higher in patients with larger tumour size (p = 0.0025), LVSI (p = 0.00023) and myometrial invasion (p < 0.0001). The areas under the ROC curves (AUCs) for distinguishing high-risk from low-risk carcinoma were 0.625, 0.829 and 0.797 for SUVmax, MTV and TLG, respectively. AUCs for both MTV and TLG were significantly larger than that for SUVmax (p = 0.0049 and p = 0.021). The optimal TLG cut-off value of 70.2, determined by ROC analysis, was found to have 72.0 % sensitivity and 74.2 % specificity for risk stratification. Conclusion MTV and TLG of primary endometrial cancer show better correlations with clinicopathological features and are more useful for differentiating high-risk from low-risk carcinoma than SUVmax.

    This study aimed to evaluate changes in natural killer (NK) cell activity and the percentage of monocytes in women with recurrent miscarriage who received medium-dose intravenous immunoglobulin (IVIg) therapy. Fourteen women with a history of six or more recurrent miscarriages of unexplained etiology received 60-g IVIg therapy (20 g daily, for three days) during early gestation. NI( cell activity in the peripheral blood decreased to 12% one week after therapy compared with before therapy (median, 22%, P<0.001) and the percentage of monocytes increased from 5.2% to 7.5% (P < 0.005). Four pregnancies ended in live births of healthy neonates, whereas the other ten pregnancies ended in miscarriages. Excluding one miscarriage with a chromosomal abnormality, the live birth rate was 30.8% (4/13). The rate of reduction of NI( cell activity in the success group (-58.8%) tended to be greater than that in the failure group (-14.8%, P = 0.057). (C) 2015 Elsevier Ireland Ltd. All rights reserved.

    Background: Human Cytomegalovirus (CMV) is the virus most frequently responsible for severe diseases of the fetus and newborn. The reported intrauterine transmission rate of CMV following primary maternal infection is approximately 40%. Invasive techniques are needed for the prenatal diagnosis of congenital CMV infection. Objectives: The aim of this study was to evaluate whether the rapidity of change in the CMV IgG avidity index (AI) is associated with the presence of congenital CMV infection among mothers with suspected primary CMV infection. Study design: The serum CMV IgG AI was repeatedly measured in 17 pregnant women with positive or borderline test results for CMV IgM together with an initial IgG AI value of <40%. Their neonates underwent polymerase chain reaction analyses for the presence of CMV DNA in the urine. The rapidity of change in the IgG AI per 4 weeks was defined as the Delta AI (%). The Delta AI of women with congenital CMV infection was compared with that of women with no infection. Results: The Delta AI of nine mothers with congenital CMV infection (median, 15.7%; range, 7.8-42.8%) was significantly higher than that of eight mothers with no infection (median, 6.5%, range, 2.0-8.8%; p < 0.001). The incidences of congenital CMV infection were 100.0%, 16.7%, and 0.0% among mothers with a Delta AI of >10, 5-10, and <5%, respectively. Conclusions: Measurement of the Delta AI in pregnant women might be useful for estimating the risk of mother-to-neonate CMV transmission. (C) 2015 Elsevier B.V. All rights reserved.

    The second edition of the Japan Society of Gynecologic Oncology guidelines for the treatment of uterine cervical cancer was published in 2011. The guidelines comprise eight chapters and five algorithms. They were prepared by consensus among the members of the Japan Society of Gynecologic Oncology Guidelines Formulation Committee and Evaluation Committee and are based on a careful review of the evidence obtained from the literature, health insurance system, and actual clinical settings in Japan. The highlights of the 2011 revision are (1) the recommended grades have been changed to five stages-A, B, C1, C2, and D; (2) the revisions are consistent with the new International Federation of Gynecology and Obstetrics staging system; (3) the roles are shared between the 'Japanese classification of cervical cancer' and the new guidelines; (4) clinical questions related to adenocarcinoma have been revised; and (5) a clinical question regarding cervical cancer in pregnant patients has been added. Each chapter includes a clinical question, recommendations, background, objectives, explanations, and references. Each recommendation is accompanied by a classification of recommendation categories. The objective of these guidelines is to update the standard treatment strategies for cervical cancer, thus eliminating unnecessary and insufficient treatment.

    Objective: Adherent placenta is a life-threatening condition in pregnancy, and is often complicated by placenta previa. The aim of this prospective study was to determine prenatal imaging findings that predict the presence of adherent placenta in pregnancies with placenta previa. Study design: The study included 58 consecutive pregnant women with placenta previa who underwent both ultrasonography and magnetic resonance imaging prenatally. Ultrasonographic findings of anterior placental location, grade 2 or higher placental lacunae (PL >= G2), loss of retroplacental hypoechoic clear zone (LCZ) and the presence of turbulent blood flow in the arteries were evaluated, in addition to MRI findings. Forty-three women underwent cesarean section alone; 15 women with adherent placenta underwent cesarean section followed by hysterectomy with pathological examination. To determine imaging findings that predict adherent placenta, univariate and multivariate logistic regression analyses were performed. Results: Univariate logistic regression analyses demonstrated that anterior placental location, PL >= G2, LCZ, and MRI were associated with the presence of adherent placenta. Multivariate analyses revealed that LCZ (p < 0.01, odds ratio 15.6, 95%Cl 2.1-114.6) was a single significant predictor of adherent placenta in women with placenta previa. Conclusion: This prospective study demonstrated for the first time that US findings, especially LCZ, might be useful for identifying patients at high risk for adherent placenta among pregnant women with placenta previa.

    Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by thrombosis and/or pregnancy complications. beta 2-glycoprotein I (beta 2GPI) complexed with phospholipid is recognized as a major target for autoantibodies in APS; however, less than half the patients with clinical manifestations of APS possess autoantibodies against the complexes. Therefore, the range of autoantigens involved in APS remains unclear. Recently, we found that human leukocyte antigen (HLA) class II molecules transport misfolded cellular proteins to the cell surface via association with their peptide-binding grooves. Furthermore, immunoglobulin G heavy chain/HLA class II complexes were specific targets for autoantibodies in rheumatoid arthritis. Here, we demonstrate that intact beta 2GPI, not peptide, forms a complex with HLA class II molecules. Strikingly, 100 (83.3%) of the 120 APS patients analyzed, including those whose antiphospholipid antibody titers were within normal range, possessed autoantibodies that recognize beta 2GPI/HLA class II complexes in the absence of phospholipids. In situ association between beta 2GPI and HLA class II was observed in placental tissues of APS patients but not in healthy controls. Furthermore, autoantibodies against beta 2GPI/HLA class II complexes mediated complement-dependent cytotoxicity against cells expressing the complexes. These data suggest that beta 2GPI/HLA class II complexes are a target in APS that might be involved in the pathogenesis.

    The aim of this study was to evaluate whether the presence of history of biochemical pregnancy (BP) was associated with clinical characteristics and the subsequent pregnancy outcome among women with recurrent spontaneous abortion (RSA). One-hundred and seventy-five RSA women with two or more clinical pregnancy losses were enrolled. The clinical characteristics were compared between 164 women with history of 0-1 BP (Group A) and 11 women with two or more BP (Group B). The frequency of previous pregnancy loss and history of in vitro fertilization and embryo transfer in Group B was higher than that in Group A; while frequency of secondary RSA in Group B was lower than Group A. The subsequent pregnancy outcome was assessed prospectively; and live-birth rate in Group A (72.9%) was higher (p<0.05) than that in Group B (41.7%). The incidence of reproductive failure (58.3%, p<0.05) and spontaneous abortion with normal chromosome (25.0%, p=0.050) in Group B was higher than those (27.1 and 5.9%, respectively) in Group A. RSA women with two or more BP had higher risk of reproductive failure and spontaneous abortion with normal chromosome together with lower chance of live-birth. The results of the present study involve important information and are helpful for clinical practitioners.

    Relaxin is essential for trophoblast development during pregnancy. Evidence shows that relaxin increases trophoblast cell migration capacity. Here, we show the effect of relaxin on protein kinase B (AKT) activation and glycogen synthase kinase 3-beta (GSK3β) inactivation as well as on the proliferation of HTR-8/SVneo cells, a model of human extravillous trophoblast (EVT). HTR-8/SVneo cells were treated with different doses of human recombinant (rH2) relaxin in serum-deprived conditions and treated for increasing time with 1 ng/mL of rH2 relaxin. Western blot analysis was performed to detect pAKT, AKT, pGSK3β, GSK3β, and actin expression. Proliferation of HTR-8/SVneo cells was analyzed by MTS assay. rH2 relaxin treatment increased the ratio of pAKT/AKT, pGSK3β/GSK3β, and proliferation in HTR-8/SVneo cells. Furthermore, AKT and GSK3β activation by rH2 relaxin was inhibited by a phosphoinositide 3-kinase (PI3K) inhibitor. This study suggests that rH2 relaxin induces AKT and GSK3β phosphorylation as well as proliferation in HTR-8/SVneo cells.

    Aims: Neurological outcomes differ considerably between symptomatic and asymptomatic infants with congenital cytomegalovirus (CMV) infection. Our objective was to characterize laboratory markers in symptomatic newborns in comparison with asymptomatic newborns with congenital CMV infection. Methods: Ten newborns with symptomatic and 13 newborns with asymptomatic congenital CMV infection were included in this 3-year prospective cohort study. Total immunoglobulin M (IgM), CMV-IgM, CMV antigenemia, and CMV-DNA in blood and urine were measured and their positive rates and quantitative values compared between the symptomatic and asymptomatic groups. Results: Fifty percent of newborns in the symptomatic group were positive based on total IgM; this was significantly lower than in the asymptomatic group (100%). Quantitative total IgM values were significantly lower, and there were significantly more copies of CMV-DNA in the blood of symptomatic newborns than in -asymptomatic newborns (median values for total IgM: 14 vs. 43 mg/dL and blood CMV-DNA: 3.2 x 10(2) vs. 3.5 x 10(1) copies/10(6) white blood cells). CMV-IgM, CMV antigenemia, and urine CMV-DNA did not differ significantly between groups. Conclusion: Low total IgM values and high blood CMV loads were associated with the presence of symptoms in newborns with congenital CMV infection.

    Objectives: The aim of this survey study was to evaluate a state of mother-to-child infections in Japan. Methods: A nationwide survey on 2714 obstetric facilities where regular maternity checkups were carried out was conducted. A primary questionnaire assessed numbers of pregnancies including induced abortion, spontaneous abortion, still-birth as well as live-birth, which were affected by congenital infections of 6 pathogens during a year of 2011. The secondary questionnaire assessed clinical information, diagnostic modality, and the outcome for each case. The clinical features and diagnostic problems were evaluated. Results: The high reply rates for the primary (73.7%) and the secondary questionnaire (100%) were achieved. The presence of congenital infections for 34 cases with cytomegalovirus (CMV), 1 with Toxoplasma gondii, 4 with rubella virus, 5 with Treponema pallidum, 8 with herpes simplex virus, and 69 with parvovirus B19 was confirmed after questionnaire assessment. The incidence of fetal demise among pregnancies with congenital parvovirus B19 infection was up to 71.0%. Eleven mothers with hydrops fetalis received prenatal fetal therapies involving fetal blood transfusion and immunoglobulin administration, whereas only three pregnancies (27.3%) ended in live-births. Conclusions: This survey study for the first time revealed the annual frequency of pregnancies with mother-to-child infections of 6 pathogens in Japan. The results involve important information and are helpful for clinical practitioners. The majority of neonates with congenital infection of CMV or T. gondii might be undiagnosed in obstetric facilities.

    Background and Purpose To investigate the diagnostic performance of diffusion-weighted imaging (DWI) and contrast-enhanced imaging in combination with T2-weighted imaging (T2WI) for magnetic resonance imaging (MRI) evaluation of intrapelvic recurrence of gynecological malignancies. Materials and Methods Sixty-two patients with suspected intrapelvic recurrence of gynecological malignancies underwent pelvic MRI including T2WI DWI, and contrast-enhanced imaging. Diagnostic performance for detection of local recurrence, pelvic lymph node and bone metastases, and peritoneal lesions was evaluated by consensus reading of two experienced radiologists using a 5-point scoring system, and compared among T2WI with unenhanced T1-weighted imaging (T1WI) (protocol A), a combination of protocol A and DWI (protocol B), and a combination of protocol B and contrast-enhanced imaging (protocol C). Final diagnoses were obtained by histopathological examinations, radiological imaging and clinical follow-up for at least 6 months. Receiver operating characteristic (ROC) analysis and McNemar test were employed for statistical analysis. Results Locally recurrent disease, lymph node recurrence, peritoneal dissemination and bone metastases were present in 48.4%, 29.0%, 16.1%, and 6.5% of the patients, respectively. The patient-based sensitivity, specificity, accuracy, and area under the ROC curve (AUC) for detection of intrapelvic recurrence were 55.0, 81.8, 64.5% and 0.753 for protocol A, 80.0, 77.3,79.0% and 0.838 for protocol B, and 80.0, 90.9, 83.9% and 0.862 for protocol C, respectively. The sensitivity, accuracy, and AUC were significantly better for protocols B and C than for protocol A (p<0.001). There was no significant difference between protocols B and C. Conclusion MRI using a combination of DWI and T2WI gives comparatively acceptable results for assessment of intrapelvic recurrence of gynecological malignancies.

    To determine the etiology of combined high-grade squamous intraepithelial lesion (HSIL) and adenocarcinoma in situ (AIS) of the uterine cervix, we examined human papillomavirus (HPV) subtypes, methylation status of the HPV-16 L1 gene, and immunohistochemical staining pattern of Krt7 in 8 cases of combined HSIL and AIS. Overall, 6 (75%) of 8 patients with combined HSIL and AIS were infected by the same subtype of HPV in both HSIL and AIS (cases 1-5, HPV-16; and case 6, HPV-18), whereas 2 (25%) patients showed infection with different subtypes of HPV (case 7, HPV-31 and -18; and case 8, HPV-52 and -16, in HSIL and AIS, respectively). The degrees of methylation at CpG islands within the HPV-16 L1 gene were almost equivalent between HSIL and AIS in cases 1-4, whereas a great difference in CpG methylation patterns between two was seen in only 1 case (case 5). In addition, both patients infected with different subtypes of HPV between HSIL and AIS were positive for Krt7 only within the AIS component. Based on these results, we propose two distinct developmental pathways of combined HSIL and AIS of the uterine cervix, the common pathway and the individual pathway.

    Background: Cytomegalovirus (CMV) causes congenital infection with high mortality and morbidity rates in affected neonates. Objectives: To evaluate the maternal IgG avidity value for the prediction of congenital CMV infection. Study design: The serum IgG avidity in all mothers was measured, and the urine of their neonates was assessed for CMV DNA in a prospective cohort study. Results: Of 759 women with a positive test for CMV IgG, 14 had congenital CMV infection. CMV IgG avidity indices in the congenital infection group (median 35.1%) were significantly lower than those in the non-congenital infection group (70.4%). A cutoff value of <40% IgG avidity index with 96.1% specificity and 64.3% sensitivity for congenital infection was determined by receiver operating characteristic curve analyses. The highest sensitivity (88.9%), 96.2% specificity, 27.6% positive predictive value, 99.8% negative predictive value, and 96.1% accuracy were found when IgG avidity was measured in < 28 weeks of gestation. Conclusion: The IgG avidity measurement with a cutoff value of < 40% IgG avidity index might be helpful in predicting congenital CMV infection, especially in < 28 weeks of gestation.

    The aim of this trial study was to assess the preventive efficacy of immunoglobulin with a high titer of anti-CMV antibody for mother-to-fetus cytomegalovirus (CMV) transmission among pregnant women with primary/acute CMV infection. The primary CMV infection in mothers was diagnosed by a positive test for CMV IgM and/or low IgG avidity. Intact type immunoglobulin with a high titer of anti-CMV antibody was injected intravenously at a dosage of 2.5-5.0 g/day for consecutive 3 days to mothers with primary CMV infection. Four pregnant women were enrolled. One pregnancy ended in no congenital infection, while two pregnancies ended in congenital CMV infection. The other one pregnancy was terminated. The mother-to-fetus CMV transmission rate was found to be high as 66.7% (2/3). This preliminary result suggests that intravenous immunoglobulin injections are not effective for the prevention of mother-to-fetus CMV transmission in the present protocol.

    Purpose: To investigate the fusion of pelvic magnetic resonance imaging (MRI) and fluorodeoxyglucose positron emission tomography (PET) for assessment of locoregional extension and nodal staging of cervical cancer. Methods: PET/computed tomography (CT), MRI, and non-fused and fusion of PET and MRI for assessing the extent of the primary tumor and metastasis to nodes were evaluated. Results: Accuracy for T-status was 83.3% for fused and non-fused PET/MRI and MRI proved significantly more accurate than PET/CT (53.3%) (P=.0077). Sensitivity, specificity, and accuracy for nodal metastasis were 92.3%, 88.2%, and 90.0% for fused PET/MRI and PET/contrast-enhanced CT; 84.6%, 94.1%, and 90.0% for nonfused PET/MRI; and 69.2%, 100%, and 86.7% for MRI. Conclusion: Fused PET/MRI combines the individual advantages of MRI and PET. (C) 2014 Elsevier Inc. All rights reserved.

    Objective: The aim of this study was to determine the risk factors for hemorrhagic shock in women with placental polyp. Materials and methods: Twelve women (group A) developed hemorrhagic shock (shock index<1.5) and received uterine artery embolization (UAE). The other 25 women (group B) had shock index<1.5 and did not receive UAE. All women underwent transcervical resection (TCR). The risk factors for the development of hemorrhagic shock, including the age, conception mode, numbers of previous abortion, gestational weeks at termination of pregnancy (TOP), blood loss weights at TOP and at TCR, were analyzed. Results: When compared with group B, group A had higher in vitro fertilization-embryo transfer (IVF-ET) pregnancy rate (58.3 versus 12.0%, p<0.01), number of previous abortion (median 1.58 versus 0.68, p<0.05), gestational weeks at TOP (median 36.5 versus 17.0 weeks, p<0.05), and blood loss weight at TOP (median 2151 versus 40 g, p<0.05). A logistic regression analysis reveled that IVF-ET (OR 41, 95% CI 1.3-1264) and blood loss weight at TOP (1.0025, 1.0006-1.0044) were independent risk factors for hemorrhagic shock. Conclusions: For the first time, IVF-ET pregnancy was found to be a risk factor for the development of hemorrhagic shock in women with placental polyp.

    Integrated positron emission tomography/computed tomography (PET/CT) with 2-[18F]fluoro-2-deoxy-d-glucose (FDG) is a useful technique for acquiring both glucose metabolic and anatomic imaging data using a single device in a single diagnostic session, and has opened up a new field of clinical oncologic imaging. FDG-PET/CT has been used successfully for the staging, treatment optimization, re-staging, therapy monitoring, and prognostication of uterine and ovarian cancers as well as various malignant tumors. The present review discusses the current role of FDG-PET/CT in the management of gynecologic malignancies, focusing on its usefulness and limitations for imaging such patients.

    Objective: To determine the factors related to adverse pregnancy outcomes and neonatal thyroid dysfunction in pregnancies complicated by Graves' disease. Study design: Thirty-five pregnancies complicated by Graves' disease were divided into two groups: adverse pregnancy outcome (n = 15) and no adverse pregnancy outcome (n = 20). Adverse pregnancy outcomes included spontaneous abortion, stillbirth, premature delivery, fetal growth restriction, and pregnancy-induced hypertension. The 31 pregnancies resulting in live births were also divided into two groups: neonatal thyroid dysfunction (n = 9) and normal neonatal thyroid function (n = 22). Serum levels of thyroid-stimulating hormone (TSH), free thyroxine (FT4), TSH-receptor antibody (TRAb), the duration of hyperthyroidism in pregnancy, doses of antithyroid medication, and the duration of maternal antithyroid medication throughout pregnancy were compared. Results: There were no significant differences in these factors between pregnancies with an adverse pregnancy outcome and those with no adverse pregnancy outcome. However, serum levels of FT4, TRAb, the duration of hyperthyroidism in pregnancy, the maximum daily dose of antithyroid medication, and the total dose of antithyroid medication were significantly different between pregnancies with neonatal thyroid dysfunction and those with normal neonatal thyroid function. Multivariate logistic regression analysis showed that the FT4 level in mothers was a significant factor related to the development of neonatal thyroid dysfunction (odds ratio 28.84, 95% confidence interval 1.65-503.62, p < 0.05). Conclusion: Graves' disease activity in women of childbearing age should be well controlled prior to conception. (C) 2014 Elsevier Ireland Ltd. All rights reserved.

    Objective: The transcatheter pelvic arterial embolization (TAE) is effective for postpartum hemorrhage (PPH). There has been a little information about the factors for ineffectiveness of TAE. The aim of this study was to determine factors associated with TAE failure for PPH. Study design: Fifty-five women who underwent TAE for intractable PPH were included. Clinical factors involving age, history of pregnancy, gestational weeks of delivery, mode of delivery, causes of PPH, complete blood count, blood loss volume, transfusion amount, shock index and disseminated intravascular coagulation (DIC) score were compared between TAE success group (n=48) and TAE failure group (n=7). Results: The uni- and multi-variate analyses revealed that advanced maternal age (OR 1.46, 95% CI 1.12-2.18) and retained placenta as a cause of PPH (15.48, 2.04-198.12) were found to be significant factors for TAE failure. Conclusion: The advanced age and retained placenta were independent factors associated with TAE failure for intractable PPH.

    Mother-to-child infections cause congenital infection with disease and sequelae. To evaluate a state of maternal blood screening for mother-to-child infections in Japan, we for the first time conducted a nationwide survey on obstetric facilities where regular maternity checkups were carried out. A questionnaire assessment involved an annual number of deliveries, scale of facilities and a state of maternal blood screening for eight pathogens. A high rate (73.7%) of reply to the questionnaire was achieved from 1990 facilities, covering 75.1% of annual number of delivery in 2011. The performance rates of blood screening were more than 99% for rubella virus, Treponema pallidum, human immunodeficiency virus (HIV), human T cell leukemia virus type 1 (HTLV-1), hepatitis B virus, and hepatitis C virus, while the rate was found to be only 4.5% for cytomegalovirus (CMV), and 48.5% for Toxoplasma gondii with large differences in regions. Most of the facilities performed blood tests for rubella virus, Treponema pallidum, HIV, hepatitis B virus and hepatitis C virus once in early pregnancy, while approximately 28% of the facilities performed blood tests for HTLV-1 once during the 2nd or 3rd trimester. Most of the facilities used HA tests for Toxoplasma gondii, whereas there was a wide variation in antibody measurement methods for CMV. Generally, the obstetric facilities in Japan have performed maternal blood screening properly according to the current recommendations. The results of this survey involve important information and are helpful for clinical practitioners.

    Purpose To investigate the impact of PET and PET/CT scanning on decision-making in management planning and to identify the optimal setting for selecting candidates for surgery in suspicious recurrent ovarian cancer. Methods A retrospective chart review was performed in patients with possible recurrent ovarian cancer after primary optimal cytoreduction and taxane/carboplatin chemotherapy who had undergone FDG PET or FDG PET/CT scans from July 2002 to August 2008 to help make treatment decisions. The analysis included 44 patients who had undergone a total of 89 PET scans. The positive PET scans were classified as follows. (1) localized (one or two localized sites of FDG uptake), (2) multiple (three or more sites of FDG uptake), (3) diffuse (extensive low-grade activity outlining serosal and peritoneal surfaces). Results Of the 89 PET scans, 52 (58.4 %) led to a change in management plan. The total number of patients in whom cytoreductive surgery was selected as the treatment of choice increased from 12 to 35. Miliary disseminated disease, which was not detected by PET scan, was found in 22.2 % of those receiving surgery. Miliary disseminated disease was detected in 6 of the 12 patients with recurrent disease whose treatment-free interval (TFI) was <12 months, whereas none of those with a TFI of >= 12 months had such disease (P = 0.0031). Conclusion PET or PET/CT is useful for selecting candidates for cytoreductive surgery among patients with recurrent ovarian cancer. To avoid surgical attempts in those with miliary dissemination, patients with a TFI of >= 12 months are the best candidates for cytoreductive surgery.

    To reduce the incidence of infants with congenital infections, women should be aware of and know prevention measures against maternal infection with mother-to-child infections during pregnancy. Our objective was to assess the awareness of and knowledge about mother-to-child infections in Japanese pregnant women. A survey of 343 Japanese pregnant women was completed. Awareness of 13 pathogens capable of mother-to-child transmission was surveyed. Knowledge about the transmission route, the most susceptible time of infection that may cause severe fetal disease during pregnancy, and methods to prevent maternal infection were investigated for four major pathogens (cytomegalovirus, rubella virus, Toxoplasma gondii, and parvovirus B19) and results were compared between these pathogens. The proportion of women aware of pathogens concerning TORCH syndrome was the following: rubella virus 76%, Treponema pallidum 69%, Toxoplasma gondii 58%, parvovirus B19 28%, herpes simplex virus 27%, and cytomegalovirus 18%. Only 8% knew how cytomegalovirus is transmitted, and only 12% knew how parvovirus B19 is transmitted; both were significantly lower than those who knew transmission routes for rubella virus or Toxoplasma gondii. The proportion of women who knew the most susceptible time for severe fetal infection by maternal acquisition of cytomegalovirus, Toxoplasma gondii, or parvovirus B19 was significantly lower than that for rubella virus. The vast majority of surveyed women were not aware of methods to prevent maternal infection with cytomegalovirus or parvovirus B19. In conclusion, current awareness of and knowledge about cytomegalovirus and parvovirus B19 infection are low in Japanese pregnant women.

    Primary leiomyosarcoma of the broad ligament is a very rare and highly malignant gynecological tumor. The authors report a 61-year-old postmenopausal woman with signs and symptoms of malignant ovarian tumor. Preoperative magnetic resonance imaging (MRI) was interpreted as being suspicious for malignant tumors, such as an ovarian cancer or a leiomyosarcoma of the broad ligament, so laparotomy was performed. Macroscopically, the tumor was revealed with a 18x13.7x9.5 cm degenerated, multiple cystic part and solid whitish part arising from broad ligament which on histopathology proved to be leiomyosarcoma. To the best of the authors' knowledge, primary leiomyosarcoma of the broad ligament has been documented in 21 reports or so, and no imaging findings are available. Here the authors present the Mill findings of primary leiomyosarcoma of the broad ligament.

    To evaluate the diagnostic value of retrospective image fusion from pelvic magnetic resonance imaging (MRI) and F-18-fluorodeoxyglucose positron emission tomography (PET) in detecting intra-pelvic recurrence of gynecological tumor. Thirty patients with a suspicion of recurrence of gynecological malignancy underwent inline contrast-enhanced PET/computed tomography (CT) and pelvic contrast-enhanced MRI for restaging. Diagnostic performance about the local recurrence, pelvic lymph node and bone metastasis and peritoneal lesion of PET/low-dose non-enhanced CT (PET/ldCT), PET/full-dose contrast-enhanced CT (PET/ceCT), contrast-enhanced MRI, and retrospective image fusion from PET and MRI (fused PET/MRI) were evaluated by two experienced readers. Final diagnoses were obtained by histopathological examinations, radiological imaging and clinical follow-up for at least 6 months. McNemar test was employed for statistical analysis. Documented positive locally recurrent disease, pelvic lymph node and bone metastases, and peritoneal dissemination were present in 53.3, 26.7, 10.0, and 16.7 %, respectively. Patient-based sensitivity for detecting local recurrence, pelvic lymph node and bone metastasis and peritoneal lesion were 87.5, 87.5, 100 and 80.0 %, respectively, for fused PET/MRI, 87.5, 62.5, 66.7 and 60.0 %, respectively, for contrast-enhanced MRI, 62.5, 87.5, 66.7 and 80.0 %, respectively, for PET/ceCT, and 50.0, 87.5, 66.7 and 60.0 %, respectively, for PET/ldCT. The sensitivity of diagnosing local recurrence by fused PET/MRI was significantly better than that of PET/ldCT (p = 0.041). The patient-based sensitivity, specificity and accuracy for the detection of intra-pelvic recurrence/metastasis were 91.3, 100 and 93.3 % for fused PET/MRI, 82.6, 100 and 86.7 % for contrast-enhanced MRI, 82.6, 100 and 86.7 % for PET/ceCT and 78.3, 85.7 and 80.0 % for PET/ldCT. Fused PET/MRI combines the individual advantages of MRI and PET, and is a valuable technique for assessment of intra-pelvic recurrence of gynecological cancers.

    The study was conducted to evaluate the effects of human relaxin on apoptosis in the human trophoblast derived HTR-8/SV neo cell line, which is a possible model of human extravillous trophoblasts (EVTs). HTR-8/SV neo cells, cultured in phenol red free RPMI1640 medium, were treated with different doses of human recombinant (rH2) relaxin in serum-deprived conditions. RT-PCR was used for evaluating relaxin receptor: RXFP1 and RXFP2 expression in HTR-8/SV neo cells. The cell death was examined by TUNEL assay. Furthermore, we investigated caspase-3, cleaved PARP and Bcl-2 expressions by Western blot analysis to recognize the translational effects of anti-apoptotic and pro-apoptotic proteins. RXFP1 and RXFP2 mRNA expression was observed in HTR-8/SV neo cells. Compared with untreated control cultures, treatment with rH2 relaxin, decreased TUNEL-positive rate in HTR-8/SV neo cells was observed. Western blot analysis revealed that treatment with rH2 relaxin decreased the expression of caspase-3 and cleaved PARP, but in contrast increased Bcl-2 expression in those cells. These results suggest that rH2 relaxin has anti-apoptotic effects on HTR8/SV neo cells by decreasing pro-apoptotic caspase-3 and cleaved PARP expression and up-regulating anti-apoptotic Bcl-2 expression.

    Purpose: To investigate the diagnostic value of retrospective fusion of pelvic MRI and F-18-fluorodeoxyglucose (F-18-FDG) PET images for assessment of locoregional extension and nodal staging of endometrial cancer. Materials and methods: Thirty patients with biopsy-proven endometrial cancer underwent preoperative contrast-enhanced PET/CT (PET/ceCT) and pelvic dynamic contrast-enhanced MRI for initial staging. Diagnostic performance of PET/ceCT, contrast-enhanced MRI, and retrospective image fusion from PET and MRI (fused PET/MRI) for assessing the extent of the primary tumor (T stage) and metastasis to regional LNs (N stage) was evaluated by two experienced readers. Histopathological and follow-up imaging results were used as the gold standard. The McNemar test was employed for statistical analysis. Results: Fused PET/MRI and MRI detected 96.7% of the primary tumors, whereas PET/ceCT detected 93.3%. Accuracy for T status was 80.0% for fused PET/MRI, and MRI proved significantly more accurate than PET/ceCT, which had an accuracy of 60.0% (p = 0.041). Patient-based sensitivity, specificity and accuracy for detecting pelvic nodal metastasis were 100%, 96.3% and 96.7% for both fused PET/MRI and PET/ceCT, and 66.7%, 100% and 96.7% for MRI, respectively. These three parameters were not statistically significant (p = 1). Conclusion: Fused PET/MRI, which complements the individual advantages of MRI and PET, is a valuable technique for assessment of the primary tumor and nodal staging in patients with endometrial cancer.

    Cytomegalovirus (CMV) causes congenital infection with high mortality and morbidity rates in affected neonates. The aim of this study was to assess whether prenatal clinical or laboratory findings in pregnant women who had high risks for primary CMV infection predicted the presence of congenital infection. Fifty pregnant women who had serum CMV IgG and positive or borderline tests for serum CMV IgM were included in this prospective study. Serum IgG avidity was measured, and PCR was conducted for CMV DNA in maternal serum, urine, and uterine cervical secretion. All neonates underwent PCR testing for CMV DNA in the urine for the presence of congenital infection. Risk factors were compared between congenital infection group and group without congenital infection. As a result, nine neonates (18%) were diagnosed as having congenital infection. The frequencies of ultrasound fetal abnormality and positive test for CMV DNA in cervical secretion, CMV IgM titer and IgM/IgG ratio in the congenital infection group were significantly higher than those in the group without congenital infection. Conversely, IgG avidity index in the congenital infection group was significantly lower than that in the group without congenital infection. By multivariate logistic regression analyses, IgG avidity index (Odds ratio 0.91, 95% CI: 0.830.99) and ultrasound fetal abnormality (291.22, 2.7231125.05), were selected independently as significant signs predictive of congenital CMV infection. Among pregnant women with positive or borderline tests for CMV IgM, when they have findings of low serum CMV IgG avidity or ultrasound fetal abnormality, the probability of congenital CMV infection may increase.

    Objective: To evaluate low-dose non-enhanced CT (ldCT) and full-dose contrast-enhanced CT (ceCT) in integrated F-18-fluorodeoxyglucose (FDG)-PET/CT studies for restaging of ovarian cancer. Materials and methods: One hundred and twenty women who had undergone treatment for ovarian cancer underwent a conventional PET/CT scans with ldCT, and then ceCT. Two observers interpreted and decided in consensus on the PET/ldCT and PET/ceCT images by a 3-point scale (N: negative, E: equivocal, P: positive) per patient and lesion site. Final diagnoses were obtained by histopathological examinations, or clinical follow-up for at least 6 months. Results: Patient-based analysis showed that the sensitivity, specificity, and accuracy of PET/ceCT was 86.9% (40/46), 95.9% (71/74), and 92.5% (111/120), respectively, whereas those of PET/ldCT were 78.3% (36/46), 95.0% (70/74), and 88.3% (106/120), respectively. All sensitivity, specificity, and accuracy significantly differed between two methods (McNemar test, p < 0.0005, p = 0.023, and p < 0.0001, respectively). The scales of detecting 104 recurrent lesion sites were N: 14, E: 6, P: 84 for PET/ceCT, and N: 15, E: 17, P: 72 for PET/ldCT, respectively. Eleven equivocal and one negative regions by PET/ldCT were correctly interpreted as positive by PET/ceCT. Conclusion: PET/ceCT is a more accurate imaging modality with higher confidence for assessing ovarian cancer recurrence than PET/ldCT. Crown Copyright (C) 2012 Published by Elsevier Ireland Ltd.

    No medical intervention guideline for prenatally diagnosed symptomatic congenital cytomegalovirus infection (CCMVI) is currently available. The aim of the study was to assess the efficacy of immunoglobulin fetal therapy for symptomatic CCMVI. With informed consent, hyper-immunoglobulin was injected into the peritoneal cavity of affected fetuses or into the maternal blood in 12 women who had symptomatic CCMVI. After immunoglobulin therapy, ultrasound examinations demonstrated the following changes: Ascites disappearance 57.1% (4/7) and a decrease in ascites volume 14.3% (1/7); improvement in intrauterine growth restriction 54.5% (6/11); disappearance of mild ventriculomegaly 40% (2/5); and in one case hepatomegaly and hydronephrosis disappeared. The survival rate of affected infants was found to be 83.3% (10/12). Concerning morbidity, 25.0% (3/12) of the infants developed normally. An additional two cases had only unilateral hearing difficulty without other sequelae. Therefore, 41.7% (5/12) of symptomatic CCMVI infants whose mothers received prenatal immunoglobulin therapies had no or only minimal sequelae (unilateral hearing difficulty). No direct adverse effects were observed. Immunoglobulin therapy may be effective for symptomatic CCMVI, reducing the incidence and severity of sequelae. To confirm the efficacy, a randomized study should be further performed. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

    A 33-year-old woman developed deep venous thrombosis at 7 gestational weeks (GW). Heparin-induced thrombocytopenia was evident at 9 GW during unfractionated heparin infusion. Immediately, anticoagulation therapies together with antithrombin (AT) infusion were commenced with the use of argatroban from 9 GW, and fondaparinux was substituted for argatroban after 24 GW. The patient had hereditary AT deficiency type I determined by laboratory findings and results of genomic DNA analysis. The pregnancy ended in full-term vaginal delivery of a healthy male without adverse effects of the anticoagulation therapies. This was the first report of a pregnant woman who developed heparin-induced thrombocytopenia caused by heparin therapy for deep venous thrombosis due to AT deficiency.

    Objective: To evaluate the effects of human relaxin on proliferation and apoptosis in cultured human uterine leiomyoma cells and normal myometrial cells. Design: In vitro experiment. Setting: Research laboratory at Kobe University Graduate School of Medicine. Patient(s): Nine patients undergoing hysterectomy for uterine leiomyoma. Intervention(s): Cultured leiomyoma cells and normal myometrial cells were treated with human recombinant (rH2) relaxin. Main Outcome Measure(s): Human relaxin receptor LGR7 expressions in cultured leiomyoma cells and myometrial cells were evaluated by immunocytochemical staining. Cell proliferation, proliferating cell nuclear antigen-positive rate, and TUNEL-positive rate were assessed by MTS assay, immunocytochemistry, and TUNEL assay, respectively. Caspase-3 expression was evaluated by Western blot analysis. Result(s): LGR7 expression was observed both in cultured human leiomyoma cells and myometrial cells. Compared with untreated control cultures, treatment with rH2 relaxin increased the number of viable cultured leiomyoma cells and the proliferating cell nuclear antigen-positive rate in those cells but not in myometrial cells. Moreover, treatment with rH2 relaxin decreased the TUNEL-positive rate in cultured leiomyoma cells but not in myometrial cells. Similarly, Western blot analysis revealed that treatment with rH2 relaxin decreased the expression of caspase-3 in cultured leiomyoma cells but not in myometrial cells. Conclusion(s): These results suggest that rH2 relaxin selectively inhibits apoptosis by down-regulating caspse-3 expression and induces proliferation in cultured human leiomyoma cells without affecting apoptosis or proliferation in normal myometrial cells.

    OBJECTIVE: The purpose of this study was to validate the therapeutic efficacy of the innovative surgical approach using laparoscopy, atelocollagen sponge, and hand-made mould on the achievement of a satisfactory neovagina in patients with vaginal agenesis. STUDY DESIGN: The current study involved four patients diagnosed as having Mayer-Rokitansky-Küster-Hauser syndrome. After creating a vaginal tunnel, the mould wrapped with atelocollagen sponge was placed within the neovagina. The hand-made mould made of expanded polystyrene was started to insert into the neovagina at 7 days after operation. Since this mould is lighter and easier to adjust compared with the previous commercialized ones, it was less stressful for the patients to master the procedure than previous methods. RESULTS: Average operation time was 124 minutes with average blood loss being 45 ml. Average hospital stay was 23 days. The mean length of the neovagina one week postoperation was 8 cm with two fingers in width in all patients. No remarkable postoperative complications were noted. At two months after surgery, the neovagina was confirmed to be completely epithelialized in all patients, assessed by Schiller's test. CONCLUSIONS: This innovative surgical procedure using a mould wrapped with atelocollagen sponge may be a more useful approach for the treatment of vaginal agenesis.

    In normal ontogenetic development, the expression of the sex-determining region of the Y chromosome (SRY) gene, involved in the first step of male sex differentiation, is spatiotemporally regulated in an elaborate fashion. SRY is expressed in germ cells and Sertoli cells in adult testes. However, only few reports have focused on the expressions of SRY and the other sex-determining genes in both the classical organ developing through these genes (gonad) and the peripheral tissue (skin) of adult XY females. In this study, we examined the gonadal tissue and fibroblasts of a 17-year-old woman suspected of having disorders of sexual differentiation by cytogenetic, histological, and molecular analyses. The patient was found to have the 46,X,inv(Y)(p11.2q11.2) karyotype and streak gonads with abnormally prolonged SRY expression. The sex-determining gene expressions in the patient-derived fibroblasts were significantly changed relative to those from a normal male. Further, the acetylated histone H3 levels in the SRY region were significantly high relative to those of the normal male. As SRY is epistatic in the sex-determination pathway, the prolonged SRY expression possibly induced a destabilizing effect on the expressions of the downstream sex-determining genes. Collectively, alterations in the sex-determining gene expressions persisted in association with disorders of sexual differentiation not only in the streak gonads but also in the skin of the patient. The findings suggest that correct regulation of SRY expression is crucial for normal male sex differentiation, even if SRY is translated normally.

    XY females are rare individuals who carry a Y chromosome but are phenotypically female. In approximately 80-90% of these cases, there are no mutations in the SRY gene, a testis-determining gene on the short arm of the Y chromosome, and the pathophysiology of XY females without SRY mutation remains unclear. In the present study, we used a molecular data mining technique to analyze the pathophysiology of an XY female with functional SRY and pericentric inversion of the Y chromosome, and compared the results with those of a normal male. Interestingly, upregulations of numerous genes included in the development category of the Biological Process ontology, including genes associated with sex determination and organ morphogenesis, were seen in the patient. Additionally, the transforming growth factor-beta (TGF-beta) signaling pathway and Wnt signaling pathway, in which most cell-cell interactions during embryonic development are involved, were altered. Alterations in the expression of numerous genes at the developmental stage, including alterations at both the gene and pathway levels, may persist as a vestige of anomalies of sex differentiation that presumably began in the fetal period. The present study indicates that a data mining technique using bioinformatics contributes to identification of not only genes responsible for birth defects, but also disorders of sex development (DSD)-specific pathways, and that this kind of analysis is an important tool for clarifying the pathophysiology of human idiopathic XY gonadal dysgenesis. Our findings could serve as one of the basic datasets which will be used for future follow-up investigations.

    Purpose: The purpose of this study is to evaluate the clinical results of treatment with a high dose of 3-dimensional conformal boost (3DCB) using a real-time tracking radiation therapy (RTRT) system in cervical cancer patients. Materials and Methods: Between January 2001 and December 2004, 10 patients with cervical cancer were treated with a high dose 3DCB using RTRT system. Nine patients received whole pelvis radiation therapy (RT) with a median dose of 50 Gy (range, 40-50 Gy) before the 3DCB. The median dose of the 3DCB was 30 Gy (range, 25-30 Gy). Eight patients received the 3DCB twice a week with a daily fraction of 5 Gy. The determined endpoints were tumor response, overall survival, local failure free survival, and distant metastasis free survival. The duration of survival was calculated from the time of the start of radiotherapy. Results: All patients were alive at the time of analysis and the median follow-up was 17.6 months (range, 4.9-27.3 months). Complete response was achieved in nine patients and one patient had a partial response. The 1- and 2-year local failure free survival was 78.8% and 54%, respectively. The 1- and 2-year distant metastasis free survival was 90% and 72%, respectively. Late toxicity of a grade 2 rectal hemorrhage was seen in one patient. A subcutaneous abscess was encountered in one patient. Conclusion: the use of the high dose 3DCB in the treatment of cervical cancer is safe and feasible where intracavitary brachytherapy (ICBT) is unable to be performed. The escalation of the 3DCB dose is currently under evaluation.

    We investigated the survival and the failure pattern of 288 patients with endometrial cancer treated with extensive surgery including systematic pelvic and para-aortic lymphadenectomy followed by cisplatin-based chemotherapy from 1982 to 2002. We correlated the failure pattern with various clinicopathologic factors to find the predictors of recurrence sites. The 5-year overall survival rates were 97.5% for stage I, 87.5% for stage II, 85.2% for stage III, and 12.5% for stage IV Notably, the 5-year survival rate was 76.5% for patients with stage IIIC disease. Among patients with a low risk (n = 92) for recurrence who received no adjuvant chemotherapy, 2 (2.2%) showed recurrent disease. Among those with intermediate (n 98) and high (n = 98) risks for recurrence who received adjuvant chemotherapy, 9 (9.2%) and 20 (20.4%) showed recurrent disease, respectively. The recurrence sites were described as follows: distant (n = 12), vaginal (n = 8), peritoneal (n = 7), pelvic (n = 2), and lymphatic (n = 2). Lymphatic failure was found beyond the area of lymphadenectomy. Architectural and nuclear grades; myometrial, lymph-vascular space, and cervical invasions; and lymph node metastasis were predictors of distant failure. Cervical invasion and lymph node metastasis were predictors of vaginal failure. For patients with stage I/II cancer, the architectural and nuclear grades were related to distant failure. Seven (63.6%) of 11 patients with a low or intermediate risk survived after relapse, whereas only 1 (4.8%) of 21 patients with a high risk survived after a recurrence. We conclude that we need to further test the efficacy of systemic adjuvant therapy using new chemotherapeutic regimens to prevent distant failure and to improve the survival of patients with endometrial cancer.

    Aim: To compare the clinical efficacy focused on post-treatment morbidity between adjuvant chemotherapy (CT) and pelvic radiotherapy (RT) after radical hysterectomy for patients with cervical cancer. Methods: A total of 125 patients with cervical squamous cell carcinoma who underwent radical hysterectomy and pelvic lymphadenectomy at Hokkaido University Hospital between 1991 and 2002 were enrolled in the study for retrospective analysis. Seventy patients with recurrent risk factors, including deep stromal invasion, lymph vascular space invasion, parametrial invasion, lymph node metastasis (LNM), and bulky tumor (>= 4 cm), received adjuvant therapy; 42 were treated with RT, and 28 were treated with CT. Almost all patients with multiple LNM received RT. Analyses were also performed on a subgroup of 50 patients without multiple LNM (23 RT, 27 CT). Clinical efficacy of post-treatment morbidity and survival was evaluated. Results: Because there were more patients with multiple LNM in the RT group, we analyzed disease-free survival in 50 patients without multiple LNM. The 3-year disease-free survival rate was 82.6% with RT and 96.3% with CT (P = 0.16). Postoperative bowel obstruction was significantly more frequent in the RT group versus the CT (P = 0.007) and no-therapy (P = 0.0026) groups. Urinary disturbance was also more frequent in the RT group than in the CT (P = 0.0016) and no-therapy (P = 0.089) groups. Conclusion: CT has the equivalent therapeutic effect as RT with fewer postoperative complications for patients with intermediate risks. A prospective randomized trial is needed to compare CT combined with radical hysterectomy and pelvic lymphadenectomy to RT or chemoradiotherapy.

    We present the first report of complete hydatidiform mole (HM) with coexisting dichorionic diamniotic twins. This pregnancy was achieved after testicular sperm extraction and intracytoplasmic sperm injection (ICSI) for azoospermia in the woman's husband. Standard in vitro fertilization may cause multisperm fertilization and increase triploid partial HM and complete HM, which arise from dispermic fertilization. In contrast, ICSI can avoid multisperm fertilization. In our case, paternal isodisomy in the molar tissue was confirmed by microsatellite analysis suggesting that it resulted from duplication of a haploid paternal genome following monospermic fertilization of an inactivated oocyte or from monospermic fertilization of an inactivated oocyte with a diploid sperm. Although the patient was eager to continue the pregnancy, the size of the HM component increased rapidly and termination of the pregnancy was required for pre-eclampsia-like symptoms at 15 weeks of gestation. After the operation, chemotherapy was initiated for persistent trophoblastic disease.

    Purpose: Since the prognosis of recurrent ovarian cancer patients is still poor, we need to establish a useful treatment strategy to achieve their long-term survival. We treated recurrent ovarian cancer patients with weekly paclitaxel (PTX)/5-fluorouracil (5-FU) followed by platinum retreatment to investigate its clinical efficacy in a preliminary manner. Methods: Sixteen patients with recurrent ovarian cancer. pretreated with taxane and platinum, were treated with weekly paclitaxel (PTX)/5-fluorouracil (FU). PTX (80 mg/m(2)) on day 1, 8, and 15 was combined with a bolus injection of 5-FU (500 mg/m(2)) on day 2, 9, and 16. Chemotherapy was given every four weeks. Patients with stable disease or progressive disease Were subsequently retreated with a platinum-containing regimen, Response was evaluated by RECIST criteria or CA 1225 criteria. Toxicities were evaluated according to the National Cancer Institute-common toxicity Criteria (NCI-CTC) version 3. Results: Among live patients with sensitive disease, one Of four patients with measurable turner and one without measurable tumor responded to weekly PTX/5-FU. Among 11 patients with resistant disease. none of five patients with measurable tumor and three of six patients without measurable tumor responded to weekly PTX/5-FU, Overall objective response rate by weekly PTX/5-FU was 31.3% (5/16). Among 16 patients, 13 patients who showed no response or progressive disease (three with sensitive disease, ten with resistant disease) received platinum retreatment after weekly PTX/5FU. All three patients with sensitive disease and three of ten patients with resistant disease revealed response to platinum retreatment. Overall objective response rate by platinum retreatment after weekly PTX/5-FU was 46.2% (6/13). Conclusions: Weekly PTX/5FU followed by platinum retreatment Could be a useful treatment strategy for recurrent ovarian cancer patients. We need to establish the standard treatment strategy for recurrent ovarian cancer patients with a poor prognosis.

    Objetive. The aim of this study was to verify whether a preoperative scoring system to estimate the risk of lymph node metastasis (LNM) in endometrial carcinoma is clinically useful for tailoring the indication of lymphadenectomy. Study design. LNM score was set up using volume index, serum CA125 level, and tumor grade/histology, which were found to be independent risk factors for LNM in a pilot study. Based on the LNM score before a validation study was started, the estimated rates of LNM (para-aortic LNM) were 3.4% (0.0%) in a low risk group, 7.7% (5.8%) in an intermediate group, 44.4% (30.6%) in a high risk group and 70.0% (50.0%) in an extremely high risk group. The validation study was carried out using data for 211 patients with endometrial carcinoma for whom three risk factors were preoperatively confirmed. Logistic regression analysis was used to determine whether these factors remain valid. The actual rate of LNM was investigated according to the LNM score. Results. Volume index, serum CA125 level, and tumor grade/histology were found to be independent risk factors for LNM in the cohort of this study. The actual rates of LNM (para-aortic LNM) were 3.2% (1.0%) in the low risk group, 15.3% (11.9%) in the intermediate group, 30.2% (23.8%) in the high risk group and 78.6% (57.1%) in the extremely high risk group. Conclusion. The actual rate of LNM for each score was fairly consistent with the estimated rate of LNM. Para-aortic lymphadenectomy may not be necessary in cases of a low risk group. A large prospective multicenter clinical trial needs to be conducted to establish the clinical usefulness of our preoperative scoring system. (c) 2006 Elsevier Inc. All rights reserved.

    The objective of this study was to assess the postsurgical bladder function by urodynamic study in patients with cervical cancer treated with nerve-sparing radical hysterectomy. A total of 27 consecutive patients were included in the study. Of the 27 patients, autonomic nerves had been completely preserved at least on one side in 22 patients (group A), and autonomic nerves could not be successfully preserved in five patients (group B). In group A, there was no significant difference in compliance at the moment of strong desire to void, maximum flow rate, and residual urine volume between before the operation and at 12 months after the operation. However, abdominal pressure at maximum flow had significantly increased in patients of group B than of group A. Detrusor contraction pressure at maximum flow had significantly decreased in patients of group B than of group A. Bladder sensation was diminished in three cases (60%) of group B but preserved in all the patients of group A. Although it is still preliminary, our surgical technique described in this report is thought to be effective for preservation of bladder function. For further evaluation of the efficacy of nerve-sparing radical hysterectomy in terms of quality of life and survival of patients, a prospective randomized trial needs to be performed.

    Background. The mechanisms of the increase in the percentage of alpha-fetoproteins (AFPs) that strongly binds to Lens culinaris agglutinin (AFP-L3) in pregnancies with a trisomy 21 fetus have not been analyzed. To investigate the oligosaccharide variants of AFP produced by normal fetuses and fetuses with trisomy 21, the lectin reactivity of AFP was analyzed. Methods. Fetal liver tissue, amniotic fluid, and maternal serum were obtained from five normal pregnancies and five pregnancies with a trisomy 21 fetus. The percentages of AFP reactive to lectins were determined by lectin-affinity electrophoresis coupled with antibody-affinity blotting. Results. The percentages of AFP-L3 in the fetal liver and the maternal serum were 23.9 and 27.0%, respectively, in normal pregnancies, and 28.7 and 38.5%, respectively, in pregnancies with a trisomy 21 fetus. There was no statistically significant difference between the percentage in the fetal liver and the percentage in the maternal serum in normal pregnancies; however, a significant difference (P < 0.01) was found in pregnancies with a trisomy 21 fetus. In regard to the percentage of AFP-L3 in the fetal liver, there was no significant difference; however, a significant difference (P < 0.05) was found in the maternal serum between normal pregnancies and pregnancies with a trisomy 21 fetus. Conclusions. The transference of the AFP-L3 fraction might be relatively high in the placentas of women carrying a trisomy 21 fetus, and this could be the one of the reasons for the increase in the percentage of AFP-L3 in the maternal serum in pregnancies with a trisomy 21 fetus.

    In addition to the loss of function, mutant p53 can possess a dominant-negative effect on wild-type p53 and may also exert gain-of-function activity. It is not clear whether the functional status of p53 mutation contributes to differences in outcome in endometrial cancer. We collected a total of 92 RNA samples of high quality from endometrial cancer tissues, and the samples were subjected to yeast functional assay and sequencing for p53 mutations. The detected mutant p53 genes were further investigated for their dominant-negative activity using a yeast-based transdominance assay. p53 mutation was found in 24 out of 92 (26.1%) tumors, of which 10 exhibited no dominant-negative activity (recessive mutation) and 14 showed dominant-negative activity. Dominant-negative p53 mutation was related to advanced stages (p = 0.01), non-endometrioid type tumors (p = 0.01) and grade 3 tumors (p = 0.04). The patients with dominant-negative mutation had significantly shorter survival than patients with no mutation (p < 0.0001) and those with a recessive mutation (p = 0.01) in the p53 gene. No difference in survival was found between the patients with tumors harboring a recessive p53 mutation and those with tumors harboring a wild-type p53. Multivariate analysis revealed that dominant-negative p53 mutation (p = 0.019), FIGO stage (p = 0.0037) and histologic subtype (p = 0.014) were independently related to patient survival. Dominant-negative p53 mutation was the most important prognostic factor for stage III/IV endometrial cancer (P = 0.0023). In conclusion, dominant-negative p53 mutation is often found in advanced stages and aggressive histologic subtypes of endometrial cancer and it is a strong predictor of survival of patients with advanced endometrial cancer. To elucidate further the role of p53 mutation in endometrial cancer, it is necessary to investigate gain-of-function activity involving dominant-negative p53 mutant proteins.

    Objective. The aim of this Study was to determine pathologic variables associated with disease-specific survival of node-positive patients with endometrial carcinoma treated with combination of surgery including pelvic and para-aortic lymphadenectomy and adjuvant chemotherapy. Methods. Survival of 55 node-positive endometrial carcinoma patients prospectively treated with Surgery and adjuvant chemotherapy between 1982 and 2002 at Hokkaido University Hospital was compared to various histopathologic variables. All patients underwent primary surgical treatment including pelvic and para-aortic lymphadenectomy followed by adjuvant chemotherapy consisting of intravenous cisplatin, doxorubicin, and cyclophosphamide. Survival analyses were performed by the Kaplan-Meier curves and the log-rank test. Independent prognostic factors were determined by multivariate Cox regression analysis using a forward stepwise selection. Results. Among 303 consecutive endometrial cancer patients treated during the period of this study, 55 patients (18.2%), including 44 without peritoneal rnetastasis (FIGO stage IIIc) and II with peritoneal metastasis (FIGO stage IV), were found to have retroperitoneal lymph node metastasis. Multivariate Cox regression analysis revealed that peritoneal metastasis and lymph-vascular space invasion (LVSI) were independently related to poor Survival in node-positive endometrial carcinoma. The estimated 5-year survival rate of stage IIIc patients with or without moderate/prominent LVSI was 50.9% and 93.3%, respectively with statistically significant difference (P = 0.0024). The estimated 5-year survival rate of stage IV patients was 20.0%. Prognosis of stage IIIc patients could be stratified into three groups by the number of positive para-aortic node (PAN) with an estimated 5-year survival rate of 86.4% for no positive PAN (n = 23), 60.4% for one positive PAN (n = 13), and 20.0% for >= 2 positive PAN (n = 8). The difference of survival rate between no or one positive PAN and >= 2 positive PAN was statistically significant (P = 0.0007 for no positive PAN vs. >= 2 positive PAN, P = 0.0319 for one positive PAN vs. >= 2 positive PAN). Multivariate analysis including number of positive PAN groups showed that LVSI, number of positive PAN groups were independent prognostic factors for survival. Survival of patients with stage IIIc disease could be stratified into three groups by combination of LVSI and number of positive PAN groups with an estimated 5-year Survival rate of 93.3% for no or one positive PAN group with nil or minimal LVSI, 62.6% for no or one positive PAN group with intermediate or prominent LVSI, and 20.0% for 2 positive PAN groups irrespective of LVSI (P = 0.0002 for no or one positive PAN group with nil or minimal LVSI vs. 2 positive PAN groups, P = 0.0223 for no or one positive PAN group with nil or minimal LVSI vs. no or one positive PAN group with intermediate or prominent LVSI, P = 0.0388 for no or one positive PAN group with intermediate or prominent LVSI vs. >= 2 positive PAN groups). Conclusions. LVSI and number of positive PAN groups were independent prognostic factors for stage IIIc endometrial cancer patients. Postoperative therapy and follow-up modality need to be individualized according to LVSI and the number of positive PAN for stage life patients. New molecular markers to predict the Prognosis of endometrial cancer patients preoperatively should be found for individualization of treatment. New chemotherapy regimen including taxane needs to be considered as an adjuvant therapy for patients with node-positive endometrial cancer. (c) 2004 Elsevier Inc. All rights reserved.

    Objective. We evaluated the primary sites of lymph node (LN) metastasis in patients during the early stage of ovarian cancer. Methods. Study 1: patients with clinical stage I and II common epithelial ovarian carcinoma (n=150) underwent systematic retroperitoneal LN dissection of the pelvic and paraaortic areas. The relationship between the incidence and location of LN metastasis and clinical and histological characteristics was examined. Study 2: we studied I I women with endometrial or fallopian tube tumors. At laparotomy, activated charcoal solution was injected into the unilateral cortex of the ovary. Ten minutes later, the retroperitoneal spaces were opened and charcoal uptake within the pelvic lymph node (PLN) and paraaortic node (PAN) as far as the level of renal vein was examined. Results. Study 1: The incidence of LN metastasis by stage was 6.5% (8/123) in stage I and 40.7% (11/27) in stage II. Among 19 patients with LN metastasis, 14 had only PAN, 2 had only pelvic LN, and 3 had both PAN and PLN metastases. Metastasis was limited to the ipsilateral side in 12 (63%) patients, but was bilateral in 5 (26%) and contralateral to the neoplastic ovary in 2 (11%). Positive peritoneal cytology was significantly (P<0.05) correlated with lymph node metastasis. Study 2: Lymphatic channels along the ovarian vessels were identified in all injected ovaries. Charcoal was deposited in the LN of all patients. The locations of these nodes included PAN in all patients, common iliac node in three, and external iliac node in one. Conclusion. PAN is the primary site of LN metastasis in ovarian cancer. Bilateral PAN dissections are necessary to determine the extent of tumors even in stage I ovarian carcinoma. (C) 2004 Elsevier Inc.

    We hypothesize that 14-3-3 sigma gene expression and its regulation by methylation can characterize histological types of primary human epithelial ovarian cancer. To test this hypothesis, ovarian cancer cell lines and 54 ovarian cancer tissue samples were analyzed for expression and methylation of 14-3-3 sigma gene using methylation specific PCR. The results of our experiments demonstrate that 14-3-3 sigma gene was methylated and inactivated in ES-2 ovarian cell line, which was derived from clear cell adenocarcinoma. Treatment of this cell line with demethylating agent 5-aza-2'-deoxycytidine restored the expression of 14-3-3 sigma gene. In human ovarian cancer tissues, the expression of 14-3-3 sigma protein was inactivated in most of the ovarian clear cell carcinoma tissues. Interestingly, 14-3-3 sigma protein expression was positive in significantly higher percentages of serous (89.5%), endometrioid (90%), and mucinous (81.8%) ovarian adenocarcinoma tissues. The ovarian clear cell carcinoma samples with inactivated 14-3-3 sigma protein were highly methylated, suggesting that inactivation of 14-3-3 sigma gene is through DNA methylation. Using direct DNA sequencing, 14-3-3 sigma gene methylation on all the 17 CpG sites was significantly higher in ovarian clear cell carcinoma as compared to other histological types of ovarian cancer (serous, endometrioid, and mucinous). This is the first report suggesting that 14-3-3 sigma gene expression and methylation status can characterize histological features of different types of ovarian cancer. (C) 2004 Elsevier Inc.

    We evaluated the clinical significance of FDG-PET to detect recurrent tumors in ovarian cancer patients. Retrospective chart review of four patients with recurrent ovarian cancer was performed. All patients underwent initial cytoreductive surgery and chemotherapy. Recurrence was suspected at 3-14 years after initial treatment. Three patients had a suspected recurrence based on elevated serum CA 125 level. All patients had increased FDG uptakes in abdominal wall, ascending colon, paraaortic node, and pararectal lesion. They underwent laparotomy to resect the tumors and histology confirmed recurrence. After completion of the operation, CA 125 level was normalized. Accurate identification of recurrent tumor nodules may have a significant impact on clinical management and the selection of patients for tumor resection. (C) 2004 Elsevier B.V. All rights reserved.

    We present the clinical characteristics of pregnancy histories and subsequent pregnancy outcomes of 13 women who tested positive for anticardiolipin beta(2)-glycoprotein I antibody (aCLbeta2GPI). Six of the 13 women had a history of recurrent spontaneous abortion (RSA). The prevalence of aCLbeta2GPI syndrome among women with RSA was very low (2.1%). Other women with aCLbeta2GPI were identified by the presence of a biological falsepositive serological test for syphilis, intrauterine growth restriction (IUGR), and a history of thrombosis. However, serum aCLbeta2GPI titers in the 13 women varied, with a wide range from 3.6 to 1468 U/mL. Their pregnancy histories, subsequent pregnancy outcomes, and complications were compared according to the classification of serum aCLbeta2GPI titers as low, moderate, or high. The history of second trimester fetal death was found only in women with high serum aCLbeta2GPI titers. All women with high serum aCLbeta2GPI titers experienced severe maternal-fetal complications such as IUGR, fetal distress, systemic thromboembolism, and neonatal sequelae in subsequent pregnancies.

    Objective: Serous adenocarcinoma (SAC) of the endometrium has a poor prognosis compared with that of typical endometrioid adenocarcinoma (EAC). The objective of this study was to determine whether SAC can be distinguished from EAC preoperatively by cervical or endometrial cytology. Study design: Cervical smears and endometrial smears obtained from 128 patients with endometrial carcinoma were reviewed. Histological types included 117 cases of EAC and 11 cases of SAC. The positive rates of cervical smears and those of endometrial smears in SAC and EAC cases were compared. Papillary clusters and bare nuclei of malignant cells in positive cervical smears were also investigated for their diagnostic significance in discriminating between EAC and SAC. Results: The positive rate of cervical smears in SAC was significantly higher than that in EAC (72.7 vs 27.4%, P < 0.05). Among cases with positive cervical smears, there were significantly more cases with papillary clusters and/or bare nuclei in cases of SAC than in cases of EAC. Conclusion: When endometrial carcinoma is clinically suspected and a cervical smear is positive, the predominance of either papillary clusters or features of bare nuclei of malignant cells in the smear may indicate the presence of SAC.

    OBJECTIVE: The aim of this study was to predict retroperitoneal lymph node metastasis during the preoperative examination of patients with endometrial carcinoma and to determine whether lymphadenectomy must be performed. STUDY DESIGN: This study was carried out on 214 patients with endometrial carcinoma. Preoperative evaluators were volume index, depth of myometrial invasion (as assessed by magnetic resonance imaging), serum CA 125 level, histologic type, and histologic grade. With the use of receiver operating characteristic curves, cutoff values of volume index and serum CA 125 levels were determined. The relationships of these evaluators with pelvic lymph node metastasis were investigated by multivariate analysis with a logistic regression model. The relationships of these evaluators with para-aortic lymph node metastasis were investigated in the same way. RESULTS: Histologic type, volume index, histologic grade, and serum CA 125 level were found to be independent risk factors for pelvic lymph node metastasis; serum CA 125 level and volume index were found to be independent risk factors for para-aortic lymph node metastasis. Among 110 cases with no risk factors for pelvic lymph node metastasis, pelvic lymph node metastasis was observed in 4 cases (3.6%). On the other hand, only 1 case of 128 cases (0.7%) with no risk factors for para-aortic lymph node metastasis actually had metastasis. CONCLUSION: Careful consideration of the possibility of the elimination of the requirement of retroperitoneal lymphadenectomy is needed in cases with no risk factors for lymph node metastasis. However, our results suggest that para-aortic lymphadenectomy may not be necessary in cases with no risk factors for para-aortic lymph node metastasis.

    Objective: The objective of this study was to investigate the predictive factors of premature rupture of the membranes (preterm PROM). Methods:The study was undertaken with cervical secretions collected from 72 consenting singleton pregnant women between 20 and 33 weeks of gestation. The levels of interleukin (IL) 1alpha, IL-1beta, IL-6, IL-8, matrix metalloproteinase (MMP) 1, MMP-2, MMP-9, tissue inhibitors of matrix metalloproteinase (TIMP) 1, TIMP-2, granulocyte elastase, and fetal fibronectin in cervical diluted specimens were measured by immunoassay, and the uterine cervix was assessed by transvaginal ultrasonography. Demographic, obstetric, clinical, neonatal, and laboratory data were analyzed by univariate analysis, multiple logistic regression, and receiver operator characteristic curve analysis. Results: Preterm PROM occurred in 6 women, and 63 women delivered at term. Multiple logistic regression analysis indicated a significant independent association with preterm PROM for the cervical IL-6 levels and cervical length. The receiver operator characteristic curve analysis revealed that an IL-6 level of greater than or equal to240 pg/ml in cervical secretions and a cervical length of less than or equal to28 mm had higher diagnostic performance in predicting preterm PROM. Conclusion: It is suggested that preterm PROM is associated with increased cervical IL-6 levels and a short cervix. Copyright (C) 2003 S. Karger AG, Basel.

    Background. To investigate the relationship between preoperative serum CA 125 levels and para-aortic lymph node (PAN) metastasis as determined by systematic pelvic and para-aortic lymph node dissection in endometrial carcinoma. Methods. This study included 180 patients (n = 55, premenopausal; n = 125, postmenopausal) with endometrial carcinoma treated by complete surgical staging. Cut-off values of preoperative serum CA 125 levels for PAN metastasis were determined by receiver characteristic curve (ROC) analysis. Logistic regression analysis was used to determine independent predictors for PAN metastasis. Results. The median serum CA 125 levels of patients with PAN metastasis were significantly higher than the levels of those with no metastasis in both premenopausal and postmenopausal groups. Based on ROC analysis, we could determine four cut-off values (70 and 210 U/mL for premenopausal patients, 20 and 60 U/mL for postmenopausal patients) and categorize the serum CA 125 levels into low, moderate and high groups. By logistic regression analysis, the CA 125 level and nuclear grade were found to be significant predictors of PAN metastasis, respectively. Using this model, the patients were stratified into three risk groups. The probabilities of PAN metastasis for patients in the low-risk, intermediate-risk and high-risk groups were less than 2%, 2-25% and more than 50%, respectively. Conclusions. Serum CA 125 levels and nuclear grade are important risk factors for PAN metastasis in endometrial carcinoma.

    Background: Cervical cancer screening is conducted by a cytological Papanicolaou (Pap) test. For screening, it is becoming increasingly important to introduce a more objective result, based on human papillomavirus (HPV) DNA test. We describe here a practical method allowing the mass detection of HPV-DNA by PCR followed by fluorogenic DNA intercalation. Methods: Samples used were cervical scrapes or biopsy specimens obtained from women who had undergone cytological testing for cervical cancer, Crude DNAs were extracted by a simplified proteinase K-boil method. Common and type-specific primers were newly designed for major types of high-risk HPVs. A fluorogenic DNA intercalator, SYBR(R) Green I was directly added to the specific PCR products. The resultant fluorescence was measured by a conventional fluorometric microplate reader. Results: The proposed PCR/microfluorometry (MFL) allowed a simple, rapid and economical detection of HPV-DNA without any use of labeling primers or probes. HPV-DNAs were found in 48.2% (123/255) of the cervical scrapes. The detection rate of HPV in cervical cancer biopsy specimen was 92.4% (61/66). Conclusions: PCR/MFL detection of HPV-DNA, followed by combined type-specific PCR, is expected to be an extremely useful tool in cervical cancer screening. (C) 2002 Elsevier Science B.V.

    Apoptosis is thought to participate pathophysiologically in the rupture of human fetal membranes (ROM). The aim of this study was to assess apoptosis of the amnion and the chorion in relation to ROM and chorioamnionitis (CAM). The amnion and chorian at the position of the cervical os and fundus of the uterus were obtained from 44 patients. Apoptotic DNA fragmentation was densitometrically determined, and the relative ratio was used for the quantitative evaluation. Among patients without CAM, the relative ratios of apoptosis in the amnion from patients with ROM were higher than those in patients without ROM (P<0.05). Among patients without ROM, the apoptotic levels in the amnion from patients with CAM were higher than those in patients without CAM (P<0.05). These were the cases with die amnion at the position of cervical os and fundus, but not with the chorion, The highest ratio of apoptosis was seen in the amnion from patients with CAM and ROM. Among patients with ROM and no CAM, the apoptotic levels at the cervical os in the amnion (P=0.059) and chorion (P<0.05) was higher than those at the fundus. The increased apoptosis of human fetal membranes was related to ROM and CAM. Apoptosis plays a role in the pathophysiology of ROM. (C) 2002 Esevier Science Ltd.

    We investigated the possible correlation between the presence of high-risk HPV DNA and the prognosis of patients with cervical dysplasia. A total of 122 patients were followed carefully by using repeated cytology, colposcopy and punch biopsy. HPV testing was performed using cytological specimens by PCR techniques. The regression rate in patients with negative HPV DNA was 51.4%, which was significantly higher than that of those with positive HPV DNA (14.1%, p<0.01). Nine cases positive for HPV DNA were progressed to CIS. In contrast, no progression was seen in negative HPV DNA group. The results show that the presence of high-risk HPV DNA in patients with cervical dysplasia is a promising marker for progressive disease.

    Hypertension in pregnancy (HP), including preeclampsia, is known to be a multifactorial disease. Recently, a Glu298Asp variant of the endothelial nitric oxide synthase gene (NOS3) was identified as being associated with coronary spasm and myocardial infarction, whereas it has been reported that endothelial nitric oxide synthase plays a role in HP. We therefore performed an association study of the Glu298Asp variant with HP among 152 H-P patients and 335 normal pregnant control individuals, in the context of other risk factors before pregnancy. The frequency of the variant GA+AA NOS3 genotypes was significantly higher in the patients (0.23) than in the controls (0.12) (P <0.01). Multivariate analysis revealed that family history of hypertension, TT genotype of the angiotensinogen gene (AGT), GA+AA NOS3 genotype, and prepregnancy body mass index greater than or equal to 24 were independent potent risk factors, after adjustment for maternal age and parity. The odds ratios of the factors were 2.7, 2.3, 2.2, and 2.1, respectively. Our results suggested that the Asp298 of NOS3 is a potent, independent risk factor for HP. (C) 2001 Wiley-Liss, Inc.

    Objectives: The objectives of this study were to cl in ica I ly characterize and seek risk factors for the patients with persistently detected alfa-fetoprotein (AFP) in the vagina without showing overt preterm premature rupture of the membranes (PROM). Study Design: The cohort study was undertaken using vaginal-cervical specimens collected consecutively between 21 and 40 weeks of gestation from 25 consenting women. Demographic, obstetric, neonatal, and laboratory data from patients with persistent positive results of AFP kit tests without showing overt leakage of amniotic fluid were compared to those from controls. Cervical levels of interleukin-1 alpha, interleukin-1 beta, interieukin-6, interleukin-8, and granulocyte elastase were measured by immunoassay, and the uterine cervix was assessed by transvaginal ultrasonography. Statistical analysis involved Fisher's exact test and Mann-Whitney U test. Results: The incidence of overt preterm PROM was significantly higher in the patients with persistently detected AFP in preterm (3 in 4 cases) than in controls (3 in 21 controls). At sampling before determination of persistently detected AFP, patients with persistently detected AFP had significantly higher cervical levels of interleukin-6 and significantly shorter cervical length than controls. Conclusions: Patients with persistently detected AFP in the vagina without showing overt preterm PROM have the risk of overt preterm PROM. Increased levels of interleukin-6 in cervical specimens and short cervical length may be risk factors for the occurrence of persistent detection of AFP in the preterm. Copyright (C) 2001 S.

    PROBLEM: The aim of this study was to assess the role of natural killer (NK) cells in pregnant women with a history of recurrent spontaneous abortion (RSA). METHOD OF STUDY: Consecutive 66 pregnant women with a history of RSA were prospectively assessed for peripheral NK cell activity, percentage of the NK cell subsets, and subsequent pregnancy outcome. RESULTS: NK cell activity in women with subsequent live birth (group I) at 4-5 gestational weeks (GW) (mean +/- SD, 32.5 +/- 12.3%) significantly decreased at 6-7 GW (28.1 +/- 12.1%) and at 8-9 GW (28.0 +/- 11.8%). NK cell activity in women with subsequent abortion with normal chromosomes (group II) at 6-7 GW (41.2 +/- 19.0%) was significantly higher than that in group I women, while NK cell activity at 6-7 GW in women with subsequent abortion with abnormal chromosomes (group III) was the same as the level in group I women. CONCLUSIONS: High NK cell activity at 6-7 GW correlates with subsequent abortion with normal chromosomes.

    A pregnant woman developed acute demyelinating poly-neuropathy (Guillain-Barre syndrome (GBS)) in the 28th week of gestation (GW) after flu-like infection. Hypertension, liver dysfunction, and a decrease in consciousness level developed at 29 GW. Blood chemical analysis revealed increased levels of liver enzymes GOT 247 IU/I and GPT 624 IU/I. Viral serological study showed a positive test for Epstein-Barr virus IgM. Weakness of bilateral facial muscles and limbs, a loss of tendon reflexes, and generalized paresthesia were detected by neurologic examinations. Over the course of 5 days, a massive dose (100 g) of intravenous immunoglobulin (MIVIg) was infused in 30 GW. An average manual muscle testing score by the Medical Research Council method and peak flow value began to be significantly restored during and after MIVIg infusions. Values of the liver enzymes gradually decreased, and improvement of the muscle weakness and dysbasia was observed. Her pregnancy normally ended in spontaneous vaginal delivery of a healthy infant in 37 GW. This is the first report confirming the efficacy of MIVIg, without plasmapheresis, in GBS-complicated pregnancy. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.

    BACKGROUND. Noncancerous cells simulating adenocarcinoma cells may interfere with the analysis of peritoneal cytology (PC) in patients with endometrial carcinoma. Immunocytochemistry (ICC) may improve the diagnosis of PC. METHODS, PC slides from 115 patients with endometrial carcinoma were reviewed. Suspicious or positive cell clusters were recovered with a cell transfer method and were subjected to ICC for MOC-31, cytokeratin 5/6, and p53. Conventional Papanicolaou staining and ICC results were compared directly on the same cells. RESULTS. By combined conventional and immunocytochemical PC (CONV-ICC-PC), cytodiagnosis was positive in 18 of 115 patients (15.7%) and suspicious in 3 of 115 patients (2.6%). According to a multivariate Cox regression analysis of patients with tumors confined to the uterus that included grade, myometrial invasion, cervical involvement, and CONV-ICC-PC, only CONV-ICC-PC was an independent prognostic factor (P < 0.05). A multivariate analysis for all of the patients studied that compared CONV-ICC-PC with staging variables revealed that only peritoneal metastasis (P < 0.0001) and lymph node metastasis (P < 0.01) were independent prognostic factors. When peritoneal metastases were excluded, CONV-ICC-PC (P < 0.01) and lymph node metastasis (P < 0.0025) were the independent prognostic factors. By cell transfer and p53 immunostaining in samples from 14 patients with malignant cells in their peritoneal washings, no deaths occurred among 5 patients with negative p53, whereas 5 of 9 patients with positive p53 died of disease at the time of data analysis. CONCLUSIONS, MOC-31 immunostaining improves the diagnosis of PC in endometrial carcinoma. Positive PC is an important prognostic factor for patients with endometrial carcinoma confined to the uterus. The p53 positive cells in PC have possible prognostic significance. Cancer (Cancer Cytopathol) 2001;93:115-123, (C) 2001 American Cancer Society.

    We report a case of agnathia-holoprosencephaly which was prenatally diagnosed based on helical computed tomography (CT) images obtained at 23 weeks of gestation. Ultrasound examination first showed the presence of alobar holoprosencephaly, but the facial structures were not clearly detailed. However, three-dimensional imaging by helical CT precisely demonstrated the most striking feature of agnathia: absence of the mandible. This technique provided us valuable information that contributed to the in utero diagnosis. In utero helical CT is a useful examination tool for the diagnosis of osteogenic abnormalities.

    The aim of this study was to evaluate the insulin dynamics of patients with gestational diabetes mellitus (GDM) and to compare perinatal outcomes according to the insulin response patterns. Twenty-two out of 925 consecutive women examined were diagnosed as having GDM. One hundred and ten women who experienced a normal pregnancy were used as controls. Plasma glucose levels and insulin responses were evaluated by a 2-hour 75-gram oral glucose tolerance test (OGTT). Immunoreactive insulin (IRI), the area under the curve (AUC) of glucose (AUCg) and insulin (AUCi), and the insulinogenic index (II = Delta IRI 30 min/Delta BS 30 min) were measured. The GDM patients were divided into three subgroups, consisting of hyper-, normo- and hypoinsulinemic groups, according to the mean +/- 2 SD of the AUCi obtained from the controls. Clinical and laboratory findings were compared among the GDM subgroups and controls. The GDM patients showed impaired insulin secretion to glucose stimuli, with low plasma insulin levels (at 30 min) and reduced insulin/glucose ratios (at 30 and 60 min) early in the 75-gram OGTT. The II and AUCi/AUCg values of GDM patients were reduced as compared with those of controls. These reduced insulin responses were remarkable in hypo- and normoinsulinemic GDM patients, but were not detected in hyperinsulinemic GDM patients. The number of babies large for their gestational age in normo- and hypoinsulinemic GDM patients was significantly higher than that in hyperinsulinemic GDM patients or controls. Hyperinsulinemic GDM patients had a high frequency of pregnancy-induced hypertension (40%). The body mass index prior to pregnancy of hyperinsulinemic GDM patients was significantly higher than that of normoinsulinemic GDM patients or controls. It was demonstrated that not only insulin secretion, but also perinatal clinical characteristics, differed among the GDM subgroups. The heterogeneity of the disease was thus confirmed.

    Congenital and acquired thrombophilia are associated with an increased risk of pregnancy-associated venous thrombosis and fetal loss. Two hundred eighty-nine patients with a history of recurrent spontaneous abortion were subjected to screening examinations for the etiology of these abortions. Endocrine abnormality (28.0%), uterine abnormality (10.4%), autoimmune diseases (1.4%), antiphospholipid antibody syndrome (4.5%), and balanced type chromosome translocation (4.2%) were found as underlying causes of recurrent abortions, and the remaining 55.0% of the 289 patients were classified as having an unexplained etiology. Congenital thrombophilia such as protein C (PC) deficiency, protein S (PS) deficiency, antithrombin deficiency, and factor V Leiden mutation was not frequently detected; only one patient had PS deficiency. A reduced factor XII activity was found at a frequency of 4.2%. The frequency of methylene tetrahydrofolate reductase gene C677T mutation in recurrent aborters (0.38) was the same as that found in a fertile control group. Although the prevalence of anti-beta2-glycoprotein I antibody (a beta2-GPI) syndrome was very low (1.7%), patients with a high titer of immunoglobulin G (IgG) class a beta2-GPI, despite anticoagulation therapy, experienced severe fetomaternal complications in subsequent pregnancies. The rate (13.8%) of positive tests for serum IgA class a beta2-GPI in patients with unexplained etiology was higher than that in the controls (0%) (P < .05). We conclude that congenital thrombophilia is rare in Japanese patients who had experienced consecutive spontaneous abortions.

    Objective: The aim of this study was to assess the role of NK cells in nonpregnant women with a history of spontaneous abortion. Study Design: 113 nonpregnant women with a history of spontaneous abortion were assessed for peripheral NK cell activity and percentage of NK cell subsets, in relation to the cause of abortions, the number of spontaneous abortions, and subsequent pregnancy outcome (n = 56). Results: Neither NK cell activity nor subsets showed a significant difference in relation to the cause or number of spontaneous abortions. NK cell activity in nonpregnant women who later experienced subsequent abortion with normal chromosomes (n = 10) (mean SD: 42.8 +/- 15.8%) was relatively higher than that in women with subsequent live birth (control, n = 39) (32.1 +/- 13.7%) (p = 0.099). NK cell activity in women who later experienced subsequent abortion with abnormal chromosomes (n = 7) (28.7 +/- 21.4%) was the same as the level in the control. Conclusion: Peripheral NK cell activity or subsets during nonpregnant status were not related to the cause or number of previous spontaneous abortions. A relation between preconceptional NK cell activity and later experiencing abortion with normal chromosomes should be further studied. Copyright (C) 2001 S. Karger AG, Basel.

    We examined peritoneal cytology (PC) for 115 cases of endometrial carcinoma using immunocytochemistry (ICC) for MOC-31, which reacts with glandular epithelial cells. PC was positive in 18 of 115 (15.7%) cases and suspicious in 3 of 115 (2.6%) cases. By a multivariate Cox regression analysis including grade, myometrial invasion, cervical involvement, and PC, only PC was found to be the independent prognostic factor for tumors confined to the uterus (p <0.05). A multivariate analysis for all the patients studied, which compared PC with staging variables, revealed that only peritoneal metastasis (p <0.0001) and lymph node metastasis (p <0.01) were independent prognostic factors. These results suggest that positive PC is an important prognostic factor for patients with endometrial carcinoma confined to the uterus.

    OBJECTIVE The aim of this study was to establish the risk of postpartum thyroid dysfunction (PPTD) in women who had normal thyroid function during pregnancy and no history of thyroid disease. DESIGN Four thousand and twenty-two consecutive pregnant women were screened for thyroid function and antithyroid antibody. Among women with normal thyroid function during pregnancy and no history of thyroid disease, thyroid function were assessed in 131 of 388 antithyroid antibody positive (Group I) and 1030 of 3503 antibody negative (Group II) women at 1 and 3 months postpartum. In Group I women who experienced PPTD, the frequency of later manifestation of Hashimoto's disease was compared according to titres of antithyroid antibodies. MEASUREMENTS Blood samples in early pregnancy, and at 1 month and 3 months postpartum were obtained using the dried blood spot method. Levels of fT4 were measured by RIA, TSH by fluoroimmunoassay or ELISA, antimicrosome antibody (AMC) and antithyroglobulin antibody (ATG) by indirect agglutination reactions. RESULTS The prevalence of PPTD at 1 month and 3 months postpartum were found to be 6.9% and 21.3% in Group I, and 5.3% and 4.7% in Group II, respectively. The prevalence of PPTD was significantly higher at 3 months postpartum in Group I (P < 0.05). 27.3% of women with PPTD in Group I were later found to have Hashimoto's disease and 9.1% manifested hypothyroidism without goitre. A high AMC titre (greater than or equal to 25 600) at 3 months postpartum in women with PPTD was related to the manifestation of Hashimoto's disease. AMC titres of PPTD women and women who developed Hashimoto's disease were significantly higher than those of control women who did not experience PPTD. CONCLUSION A high prevalence of PPTD was found in women with antithyroid antibodies who were euthyroid during pregnancy. Prolonged follow-up of the subsequent thyroid function may be needed in women who experience PPTD and/or show a high titre of antithyroid antibody.

    Background: The occurrence of pelvic lymphocysts is an important complication following systematic lymphadenectomy for gynecological malignancies. We employed a procedure to prevent vaginal shortening following radical hysterectomy and we examined whether this procedure could be effective in preventing pelvic lymphocyst formation. Methods: We studied the incidence of lymphocysts in 190 patients with 84 cervical cancers, 74 endometrial cancers and 32 ovarian cancers, using computed tomographic examination at 3 and 6 months subsequent to the surgery. The surgery included radical hysterectomy and a procedure to prevent vaginal shortening (101), modified radical hysterectomy (79) and simple hysterectomy (7), with systematic lymphadenectomy. Results: There was a significant difference in the incidence of pelvic lymphocysts between cervical cancer (4.8%) and ovarian cancer (18.8%). The postoperative incidence of lymphocyst formation in patients undergoing radical hysterectomy with the procedure to prevent vaginal shortening (5.9%) was significantly lower than in those who underwent modified radical hysterectomy (15.2%). Conclusion: Our procedure to prevent vaginal shortening could be effective in preventing not only the shortening of the vagina but also the occurrence of pelvic lymphocysts in patients undergoing radical hysterectomy with systematic lymphadenectomy for gynecological malignancies.

    We describe a surgical procedure and post-operative management for the prevention of vaginal shortening following radical hysterectomy. A total of 452 patients who underwent hysterectomies were examined prospectively depending on the operation method. This study showed that our procedure was effective in the prevention of vaginal shortening following radical hysterectomy. Preservation of the ovaries appeared to be important in preventing vaginal shortening, and post-operative hormone replacement therapy was not as effective as the preservation of the ovaries. The effect of external irradiation on vaginal shortening was not conspicuous in the case that the ovaries were preserved.

    A 35-year-old Japanese woman with a low level (42-54%) of blood antithrombin (AT) III, experienced two induced abortions due to deep venous thrombosis at 8 weeks of gestation (GW) and cerebral thrombosis at 10 GW, The present pregnancy was successfully managed with intravenous administration of AT III (6,000-8,000 U/wk), Analysis of polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP) for exons 3A and 4 of the AT III gene (AT3) using her DNA revealed extra expansion bands with altered migration. The DNA sequencing demonstrated novel mutations in exon 3A of AT3: a G to T substitution at nucleotide position 5333 in codon GAG for Glu 113, causing a stop codon (E113X), and an A to T substitution at position 5338 in codon AAA for Lys 114, forming Asn (K114N). These novel mutations, especially E113X, in AT3 may be related to recurrent thrombosis in the pregnancy. (C) 2000 Wiley-Liss, Inc.

    Congenital thrombophilia is known to cause significant maternal complications, and possibly has an adverse effect on normal feta I development, The aim of this study was to assess the prevalence of factor XII (FXII) deficiency in women with a history of recurrent miscarriage. Two hundred and forty-one consecutive Japanese women with a history of two or more recurrent miscarriages were prospectively assessed for their etiology by conventional screening methods. Seven women were found to have reduced FXII activity (19.2-46.1%) and prolonged activated partial thromboplastin time (33.3-51.3 s). Of these 7 women, 6 had experienced early pregnancy losses, while 1 woman had experienced repeated midtrimester fetal losses with coincidental gestational thrombocytopenia, In 241 women with a history of recurrent miscarriage, the prevalence of FXII deficiency was 2.9%.

    We describe a surgical procedure and post-operative management for the prevention of vaginal shortening following radical hysterectomy. A total of 452 patients who underwent hysterectomies were examined prospectively depending on the operation method. This study showed that our procedure was effective in the prevention of vaginal shortening following radical hysterectomy. Preservation of the ovaries appeared to be important in preventing vaginal shortening, and post-operative hormone replacement therapy was not as effective as the preservation of the ovaries. The effect of external irradiation on vaginal shortening was not conspicuous in the case that the ovaries were preserved. © 2017 Wiley. All rights reserved.

    Telomerase activity has been implicated in the progression of various human tumors. Our aim was to evaluate telomerase activity and to compare it with histo-pathological factors in uterine endometrial carcinoma, to look for possible correlations. Telomerase activity was measured by dilution analysis using a PCR-based telomeric repeat amplification method and detected in 31 of 35 primary endometrial carcinoma tumor specimens. High telomerase activity, detected after 100-fold dilution of extracts, was identified in 15 specimens. There was no significant correlation between the positive telomerase activity and tumor surgical stage or histopathological factors. However, high telomerase activity was significantly correlated with advanced surgical stage and with pelvic lymph node metastasis. Our findings suggest that an increase in telomerase activity may be associated with tumor progression and that its level may have a prognostic value in endometrial carcinoma. Int. J. Cancer (Pred. Oncol.) 84:529-532, 1999. (C) 1999 Wiley-Liss, Inc.

    PROBLEM: Maternal anti-SSA(B) antibody crosses the placenta and causes fetal myocarditis, congenital heart block (CHB), hydrops fetalis, and intrauterine fetal death. The aim of this study was to evaluate corticosteroids' efficacy as a treatment for CHB. METHOD OF STUDY: One fetus with complete CHB and one fetus with incomplete CHB due to anti-SSA(B) antibody received maternal prednisolone (PSL) and dexamethasone (DEXA) treatments. Heart rate, cardiothoracic ratio (CTR), left ventricular fractional shortening (FS), and preload index (PLI) were longitudinally measured by serial fetal echocardiograms. RESULTS: In the former case, after maternal PSL/DEXA administration,improvement of cardiohemodynamics, i.e., the reduction of PLI from 1.7 to 0.4, CTR from 70 to 52%, and FS from 63 to 54% were observed. In the latter case, second degree 2:1 block was converted to 3:2 block/sinus rhythm, resulting in the increase of the fetal heart rate from 65 to 116 beats per minute (bpm). CONCLUSIONS: We disclosed for the first time the beneficial effects of corticosteroids in the fetal cardiohemodynamics and conduction system of affected fetuses with the presence of maternal anti-SSA(B) antibodies.

    The carbohydrate structure of glycoproteins is considered to be tissue- specific or cell type-specific, but there have been no reports on the differences of the carbohydrate structure of alpha-fetoproteins (AFPs) produced by histologically identical tumors in different tissues. The lectin affinity electrophoresis of hepatoid adenocarcinomas and yolk sac tumors from different organs suggested that either the tumor heterogeneity or the tissue specificity is possibly involved, the lectin reactivity of the AFP sugar chain structure produced by the tumors in different tissues.

    We investigated the tumor marker for malignant Brenner tumors, which had not been established because of the rarity and variable histological criteria. Representative areas of two cases of malignant Brenner tumor were investigated by means of the peroxidase-antiperoxidase method using monoclonal antibody to CA125 and CA72-4 antigen and the streptavidin-biotin immunoperoxidase complex method using monoclonal antibody to SCC antigen. Based on clinical course and immunohistochemical studies, serum CA125 and CA72-4 for Case 1 and SCC and CA72-4 for Case 2 were appropriate tumor markers for the establishment of the extent of tumor burden before treatment and to monitor the response to therapy. The discrepancy of the tumor markers of the two present cases is considered to be a reflection of the difference in the malignant component of these cases. However, serum CA72-4 was an appropriate tumor marker for both malignant Brenner tumors.

    PROBLEM: The aim of this study was to elucidate fetomaternal risks in systemic lupus erythematosus (SLE)-complicated pregnancy. METHOD OF STUDY: Pregnancy course, complications, and fetal outcome in 82 pregnancies of 55 patients with SLE were investigated. RESULTS: These 82 pregnancies resulted in 14 fetal losses and 66 live births. Without clinical manifestation of SLE-flare, 4 of 8 patients who had low serum complement activity during the pregnancies delivered small-for-date neonates. The rate of the intrauterine growth retardation was significantly higher than that observed in pregnancies with normal complement activity. The frequency of premature deliveries (60%) in patients who received more than 15 mg/day of prednisolone was significantly high when compared with pregnancies maintained by 0-15 mg/day (13.1%) CONCLUSIONS: These data demonstrate the preconceptional and perinatal management necessary in SLE and suggest that the pregnancy with hypocomplementemia, the disease activity, and/or a relatively high maintenance dose of corticosteroid should be carefully managed and monitored.

    The aim of this study was to evaluate risk factors for occurrence of neonatal passive immune thrombocytopenia (PIT) in pregnancy complicated by idiopathic thrombocytopenic purpura (ITP). We studied 63 pregnant women with ITP and the 66 neonates retrospectively. Neonatal platelet counts were compared with maternal platelet counts, platelet-associated gamma G immunoglobulin (PAIgG) values, and the presence of antiplatelet antibody in the maternal circulation, history of previous PIT, maternal treatments for ITP, and other maternal or neonatal factors. PIT (platelet counts <100 x 10(3)/mu L) was observed in 9 (14.3 %) of 63 pregnancies. Presence of circulating antiplatelet antibody in maternal blood, splenectomy prior to pregnancy, and history of previous PIT were observed more frequently with statistical significance in patients giving birth to neonates who developed PIT. No effect on occurrence of PIT was found by the administration of corticosteroids or immunoglobulin. Splenectomy prior to pregnancy was found by logistic regression analysis to be a single significant variable (p = 0.021, odds ratio 7.20, confidence intervals: 1.35 to 38.3) among the risk factors for PIT.

    The International Federation of Gynecology and Obstetrics (FIGO) adopted surgical staging criteria in 1988. Many studies have shown that histologic grade, nuclear grade, lymphvascular space invasion and cell type are also important predictors of survival. It has not been clarified, however, how to integrate these histopathologic variables into the process of estimating individual prognosis. We performed Cox multivariate regression analysis to create models that incorporate various histopathologic factors for estimating the prognoses of patients with endometrioid adenocarcinoma of the uterine corpus. Our study was based on data from 206 patients who underwent complete surgical staging, including systematic pelvic and para-aortic lymph node dissection. Two models resulted: one included depth of myometrial invasion, paraaortic node metastasis and the number of sites involved by the tumor among the cervix, ovary and pelvic lymph nodes (which we designated as extracorporeal spread score, ECS) and the other incorporated nuclear grade and lymph-vascular space invasion as variables. These 2 models enabled the prognosis for patients with endometrioid adenocarcinoma to be stratified into several levels according to hazard ratio. Comprehensive integration of the histopathologic prognostic factors, categorized into those relating to tumor extent and those relating to tumor virulence, should facilitate the estimation of individual prognosis more accurately than FIGO staging alone.

    Aims-To investigate a potential diagnostic use of alpha fetoprotein (alpha FP) isoform analysis by lectin affinity electrophoresis to distinguish between endodermal sinus tumours arising in the vagina in infants from those at other sites. Methods-alpha FP in the serum of a patient with a vaginal endodermal sinus tumour was analysed for its isoforms by lectin affinity electrophoresis. The isoforms were compared with that of cord serum, sera of hepatoid adenocarcinoma of the uterus, and endodermal sinus tumour of the ovary. Results-The isoforms of alpha FP obtained by lectin affinity electrophoresis in the serum of the patient with vaginal endodermal sinus tumour differed from the isoforms of alpha FP in the cord serum of normal neonates, and sera of patients with hepatoid adenocarcinoma of the uterus or endodermal sinus tumour of the ovary. Conclusions-Endodermal sinus tumour arising in the vagina could be distinguished from that in the ovary by the lectin affinity electrophoresis, and a potential diagnostic use of alpha FP isoform analysis by the lectin affinity electrophoresis for the detection of the endodermal sinus tumour in infants was demonstrated.

    Background. There has been a controversy about the prognostic significance of positive peritoneal cytology in endometrial carcinoma. Materials and methods. Peritoneal cytology was obtained at the time of surgery, including systematic retroperitoneal lymph node dissection, in 114 patients. Results. The incidence of positive peritoneal cytology was 35.1%, The 5-year survival rates of the stage IIIA and IIIC (FIGO, 1988) cases were 82.8% and 58.3%, respectively, In pathological stage I (the disease was histologically confined to the uterine corpus), there was no significant difference in 5-year survival rates between patients with and without positive peritoneal cytology, Though the patients in stage IIIA who had only positive peritoneal cytology were given no postoperative therapy unless they had extrauterine disease, no patients developed recurrence, In stages IIIC and IV, the prognosis was significantly poorer for patients with positive peritoneal cytology than for those with negative cytology. Conclusion. Positive peritoneal cytology is not an adverse prognostic factor of endometrial carcinoma if disease is limited to the uterus.

    <文献概要>血栓性素因のうち抗リン脂質抗体症候群のみ,不育症の明らかな原因といえる。そのほかの血栓性素因としては,わが国ではプロテインS低下,凝固第XII因子低下が代表的である。これらの(抗)凝固因子低下と不育症には弱い関連があるものの,治療が妊娠予後を改善するエビデンスは乏しい。不妊症と血栓性素因との関連についてはさらにエビデンスに乏しく,血栓性素因のある不妊・不育症患者の全例に抗凝固療法を行うべきではない。抗リン脂質抗体症候群については確立された治療法(低用量アスピリンとヘパリンの併用)があり,不育症(生化学的妊娠の反復を含む)や妊娠34週未満早産,胎児発育不全,妊娠高血圧症候群,常位胎盤早期剥離,HELLP症候群などの妊娠合併症があれば,不妊治療施設でもプレコンセプションケアとして積極的に診断検査基準に含まれる抗リン脂質抗体(aPL)を測定する。一方,血栓症の既往からみつかった血栓性素因についてはまったく対応が異なり,不妊治療に伴う卵巣過剰刺激症候群(OHSS)の徴候がみられた場合や妊娠が明らかとなった場合は,積極的にヘパリンを含む抗凝固療法を行う必用がある。また,凝固検査の評価においては,本検査が非常に繊細な検査であり,採血・検体処理手技により検査値が大きく変動する可能性があることに留意し,より正確な凝固検査を実施する体制を整備していくことが重要である。

    子宮頸部小細胞癌は子宮頸部に発生する高異型度神経内分泌腫瘍であり、子宮頸癌の1〜3%を占めるに過ぎないが、早期に再発・転移をきたすことが多く予後不良な疾患として知られている。統一した治療方針は確立されていない。一方で子宮頸癌の治療において、腫瘍径が大きく、摘出が困難な進行症例では、術前化学療法が考慮される。今回我々は、局所進行子宮頸部小細胞癌に術前後の化学療法を施行し、良好な経過を得られたので報告する。症例は76歳。多量の不正出血を主訴に来院した。子宮傍組織に至る86mm大の腫瘤を認め、IIB期と診断した。組織診はsmall cell carcinomaであった。術前化学療法としてイリノテカン+シスプラチン(CPT-P)療法を1コース施行したところ、著明な縮小を認めたため、直ちに広汎子宮全摘術、両側付属器摘出術、骨盤リンパ節郭清、傍大動脈リンパ節郭清を行った。術後に2コースを追加し、術後7ヵ月で再発なく外来経過観察中である。転移のない局所進行子宮頸部小細胞癌では、術前後の化学療法が奏功し、予後を改善する可能性がある。(著者抄録)

    過去10年間に当科で経験した正常胎児と全奇胎の双胎(CHMCF)3例について報告した。CHMCFの診断週数は12〜14週で、2例は排卵誘発による妊娠であった。母体合併症は妊娠悪阻が1例、性器出血が3例であった。診断後、妊娠継続に関するリスクについて十分な説明を行ったところ、2例は妊娠中絶を希望したが、残りの1例は希望により妊娠継続をしていた。だが、臨床的侵入奇胎のため妊娠21週1日目で人工妊娠中絶となった。3例中2例では続発性疾患(奇胎後hCG存続症1例、臨床的侵入奇胎1例)を認め、化学療法にて寛解が得られた。

    <ポイント>性器ヘルペスは単純ヘルペスウイルス(HSV)による性行為感染症である。臨床的に、初発と再発に分類され、さらに初発は初感染初発と非初感染初発にわけられる。病変からの検体を用いた病原診断、または、病歴、臨床症状、局所所見に基づいた臨床診断を行う。HSVの増殖を抑制する抗ウイルス薬が有効であり、アシクロビルもしくはバラシクロビルを使用する。妊婦が性器ヘルペスに罹患すると、産道感染をきたし新生児ヘルペスの原因となる。分娩時にヘルペス病変が外陰部にある場合には帝王切開が強く勧められる。初感染初発から1ヵ月以内か、再発または非初感染初発発症から1週間以内に分娩となる場合には予定帝王切開を考慮する。(著者抄録)

    47歳女。39歳時に腹腔鏡下子宮筋腫核出術、40歳時に甲状腺乳頭癌に対して甲状腺摘出術の既往があった。無月経、不正性器出血で受診した際に、骨盤内から後腹膜腔へ発達する巨大な腫瘍を指摘された。PET-CTでは腫瘍部位にFDGの有意な集積を認めず、有茎性漿膜下筋腫を疑った。原発不明腫瘍の診断で手術を施行した。病理組織では、腹腔鏡下子宮筋腫核出術の既往があることから、腹腔鏡下筋腫核出術後に発生した医原性parasitic myomaと推察した。当時の手術記録を取り寄せたところ、子宮後壁頸部近くの97mm大の筋腫を核出後、モルセレーターを使用し体外に摘出していた。その際の残存筋腫が栄養血管を獲得しながら発育し、後腹膜腔にまで達する巨大なparasitic myomaとなったと推測された。腫瘍および子宮頸部・体部細胞診において悪性所見は認めず、不正性器出血に関しては閉経周辺期の機能性子宮出血と考えられた。

    子宮体部扁平上皮癌(primary endometrial squamous cell carcinoma:PESCC)は非常に稀な症例である。今回われわれは子宮留膿腫に伴う発熱・腹痛を初発症状として発見され、治療を行った子宮体部扁平上皮癌の1症例を経験したので報告する。患者は79歳、4経妊2経産、50歳で閉続。内分泌疾患精査のため。当院内科入院中に下腹部痛と発熱の症状が出現し、腹部CTにて子宮腫大と子宮内腔の液体貯留を認めたため、当科へ紹介となった。経腟超音波・骨盤MRIでは子宮底部に充実性腫瘤を認め、子宮体癌が疑われたが、子宮内膜組織診では異型を認めなかった。しかし、初診時の腫瘍マーカー検査にてSCC抗原が97.9ng/mlと異常高値であったため、全身検索目的にてFDG-PETを施行したところ、子宮体部腫瘍に一致して強い集積を認めた。そのため子宮体部悪性腫瘍を疑い、初診の2ヵ月後に腹式単純子宮全摘術+両側付属器切除術を施行した。術後病理組織診断で、子宮体部原発扁平上皮癌Ic期と診断された。年齢を考慮し後療法は施行せずに外来にて経過観寮中であるが、術後15ヵ月で再発兆候を認めていない。(著者抄録)

    An ectopic ovary is a very rare condition. A 27-year-old woman underwent laparoscopy because of a dermoid cyst on the right ovary and was found to have a cystic mass in the mesentery of the sigmoid colon. Despite thorough inspection, her left ovary was not found in the usual place. The left infundibulopelvic ligament was also nonexistent. Pathological examination revealed ovarian stromata in the cystic mass in the mesentery of the sigmoid colon.

    卵巣腫瘍症例におけるDVTの術前診断の指針について検討した.2006年1月~2010年6月の間に,当科で術前に血漿D-dimer値を測定した卵巣腫瘍193例(良性115例,境界悪性15例,悪性63例)を対象とした.主治医の判断で術前に下肢静脈ドップラー超音波検査を施行したのは32例(良性9例,境界悪性6例,悪性17例)で,DVTと診断された症例は18例(良性5例,境界悪性2例,悪性11例)であった.DVTの有無と良・悪性別,年齢別,症状の有無,最大腫瘍径,血漿D-dimer値などの項目との関係について解析したところ,DVTと診断された症例の割合は,良性腫瘍に比し悪性腫瘍で有意に高く,下肢の腫脹・浮腫・疼痛・熱感などの症状を有する症例は,症状がない症例に比し有意にDVTと診断された症例が多いことが明らかになった.またDVTの有無と,最大腫瘍径値,BMIの多寡等との間には有意な関連を認めなかったが,血漿D-dimer値が高い症例でDVTと診断されることが多かった.DVTと診断した18例は,すべて血漿D-dimer値が3.0μg/ml以上であったが,一方でDVTに関連した臨床症状のなかった症例が6例あった.本検討により,DVTに関連した臨床症状のある症例や,術前の血漿D-dimer値が少なくとも3.0μg/ml以上の症例であれば,全例術前に下肢静脈ドップラー超音波検査を施行しDVTをスクリーニングすることが重要であると考えられた.〔産婦の進歩63(3):271-276,2011(平成23年8月)〕

    <B>Objectives:</B> The purpose of this study was to determine the feasibility and radicality of endoscopic radical hysterectomy (ERH) and endoscopic modified radical hysterectomy (EmRH) combined with pelvic lymphadenectomy (ELND) in invasive cervical cancer patients.<BR><B>Methods:</B> Five patients with invasive cervical cancer underwent ERH or EmRH between May 2003 and March 2007 at Hokkaido University Hospital. Two patients with stage I a adenocarcinoma underwent an EmRH, and two patients with stage I b1 and one patient with stage II a underwent an ERH. All patients gave their informed consent to this experimental procedure before surgery.<BR><B>Results:</B> The median age of patients was 39 years (range, 33-45 years), and the median body mass index was 20.2 kg/m<SUP>2</SUP> (range, 18.5-23.7 kg/m<SUP>2</SUP>). The maximum tumor diameter was 20mm in 1 patient, and ≤10mm in 4 patients. The pathologic subtype was squamous cell carcinoma in 2 patients, and adenocarcinoma in 3 patients. The median operative time was 734 min (range, 583-974 min), the median blood loss was 890 ml(range, 280-2650 ml), the median number of lymph nodes removed was 77 (range, 47-103), and the median length of vaginal cuff removed was 20mm(range, 10-25mm). The median duration of hospitalization post-operatively was 16 days (range, 13-23 days). A post-surgical infection occurred in one patient, but no severe complications were noted. There were no relapses after a mean follow-up period of 31.8 months (range, 15-71 months).<BR><B>Conclusions:</B> An ERH or EmRH with ELND is feasible and might be beneficial for early invasive cervical cancer.

    Background: Submucosal myoma has been treated with hysteroscopic transcervical resection (TCR) . However, in cases of unstalked submucosal myoma over 3cm in diameter, TCR could lead to not only extended operation time but also extensive thermal damage on endometrium by electrocoagulation. In this study, we validated the feasibility and utility of total Laparoscopic approach for submucosal myoma treatment.<BR>Materials and Methods: Total laparoscopic myomectomy (TLM) was performed on 12 women with submucosal myoma. Our TLM procedure was as follows: a balloon catheter was detained in the uterine cavity to evaluate the degree of submucosal projection by sonohysterography. Culdotomy was performed to set acrylic vaginal pipe into intraperitoneal cavity as a larger access port. After intramyometrial injection of vasopressin, a transverse incision was made to extract myomas. As myomectomy progressed, endometrium filled with indigocarmine through a detained balloon catheter appeared transparent-blue bulge, which helped easy recognition of endometrial injury. Uterine wall was sutured layer by layer without tucking the endometrium into myometrium. The enucleated nodules were removed via a vaginal pipe.<BR>Results: The median size of dominant submucosal myomas was 5cm, the median blood loss was 120ml and the median operating time was 162 minutes. There was no correlation between the degree of submucosal projection and endometrial defect. Minimal endometrial damage was observed and one of 3 infertile patients was pregnant after surgery.<BR>Conclusion: TLM was feasible in the cases of submucosal myoma as well as intramural and subserosal myomas.

    卵巣癌の標準化学療法はpaclitaxel/carboplatin併用療法である。このregimenは初回治療はもとより、症例によっては再発時にも用いられる。そのため、投与回数が重なった時にcarboplatinの急性過敏症反応を起こすことがある。最近、われわれはcarboplatinによる急性過敏症反応を3症例経験した。症状は頻脈、胸部苦悶感、呼吸困難などであった。そのような症例に対しcisplatinを用いた脱感作療法を行ったところ、全例にプラチナ製剤の再投与が可能であった。この方法は安全で、プラチナ感受性のある症例には有用であると考えられたので報告する。(著者抄録)

    目的:我々は広汎子宮全摘術に下腹神経、骨盤内臓神経、骨盤神経叢およびその膀胱枝の系統的温存を併用してきた。骨盤神経叢子宮枝を選択的に切断し骨盤神経叢と傍腟結合織を分離させる手技が重要である。我々の行う術式の有用性を尿流動態学的検査で検証する。方法:対象は広汎子宮全摘術を行った子宮頸癌49例でA群:系統的自律神経温存を行った43例(1b1期17例、1b2期10例、2a期4例、2b期12例)、B群:系統的自律神経温存を行わなかった6例(1b1期4例、2b期2例)である。術前、術後1、3、6、12ヵ月の各時点において最大尿意時膀胱コンプライアンス(Cves)、最大尿流量率(MFR)、最大尿流量時腹腔内圧(PabdQmax)、最大尿流量時排尿筋圧(PdetQmax)、残尿量(Resid)を求めた。各パラメータの経時的推移はrepeated measure one-way ANOVAで解析し、有意差ありと判定された場合にFisher's protected least significant difference法を用いて各時点間の有意差を検討した。尿意についても評価を行った。成績:年齢、進行期分布、腫瘍径、切除腟長は両群間で差を認めなかった。A群においてCves、MFR、Residは術前と術後12ヵ月の間に差を認めなかった。PabdQmaxは手術により増加、PdetQmaxは低下したが、B群と比較してその影響は有意に小さいことが示された。A群で尿意の異常を認めた例は7%に過ぎなかったが、B群の67%で尿意が減弱した。結論:骨盤神経叢子宮枝を選択的に切断し、骨盤神経叢と傍腟結合織の分離を行う系統的自律神経温存法は切除腟長を縮小することなく膀胱機能温存を可能とするために重要な手技である。(著者抄録)

    1988〜2001年に妊孕能温存治療を行った悪性卵巣腫瘍50例を対象とし,治療成績,卵巣機能への影響を検討した.初回手術は患側附属器摘出49例,両側腫瘍核出1例であり,片側附属器摘出例中46例に対側卵巣楔状切除,21例に大網切除,17例に後腹膜リンパ節摘出を施行した.33例に術後化学療法を施行し,etoposideを5回以上投与した群では排卵回復までの期間は有意に遅延していた.CAP療法を6コース施行した漿液性腺癌1例では卵巣機能が廃絶した.妊娠を希望した21例中,妊娠は8例に認めた.手術治療のみでも高い治癒率が期待できるIa期,grade 1の上皮性悪性腫瘍や境界悪性腫瘍,抗癌剤感受性の高い悪性胚細胞腫瘍例において,治療が過剰にならないことが妊娠率向上につながると考えられた

    We experienced anesthetic management for ECT in a patient with psychiatric disease during the third trimester of pregnancy. The 24 year-old patient had been on oral antipsychotics prescribed to treat schizophrenia for ten years. Her signs and symptoms deteriorated during pregnancy in spite of increased doses of antipsychotics. With tocolytic agent administered intravenously, anesthesia was induced by intravenous thiamylal immediately followed by intravenous suxamethonium for muscle relaxation. Alternative current was applied on both side of the head after the sufficient anesthesia had been obtained. The patient received intermittent mandatory ventilation by breathing mask with 100% oxygen during the procedure. Along with monitoring of maternal hemodynamic variables and arterial oxygen saturation (Spo2), fetal heart rate and uterine contraction were recorded by cardiotocogram throughout the procedure. At the first two treatments, the patient showed neither significant uterine contraction nor fetal heart rate changes. At the third treatment, continuous uterine contraction refractory to tocolysis was recorded for six minutes, resulting in fetal bradycardia. At the sixth treatment, general anesthesia was induced and maintained by sevoflurane in oxygen followed by suxamethonium for muscle relaxation. The uterine contraction was remarkably diminished and fetal heart rate remained unchanged during the procedure. In conclusion, inhalation anesthesia is beneficial for ECT in the last stage of pregnancy to reduce uterine contraction by potential uterine relaxation effect of anesthetics.

    PROBLEM: The aim of this study was to elucidate fetomaternal risks in systemic lupus erythematosus (SLE)-complicated pregnancy. METHOD OF STUDY: Pregnancy course, complications, and fetal outcome in 82 pregnancies of 55 patients with SLE were investigated. RESULTS: These 82 pregnancies resulted in 14 fetal losses and 66 live births. Without clinical manifestation of SLE-flare, 4 of 8 patients who had low serum complement activity during the pregnancies delivered small-for-date neonates. The rate of the intrauterine growth retardation was significantly higher than that observed in pregnancies with normal complement activity. The frequency of premature deliveries (60%) in patients who received more than 15 mg/day of prednisolone was significantly high when compared with pregnancies maintained by 0-15 mg/day (13.1%). CONCLUSIONS: These data demonstrate the preconceptional and perinatal management necessary in SLE and suggest that the pregnancy with hypocomplementemia, the disease activity, and/or a relatively high maintenance dose of corticosteroid should be carefully managed and monitored.

    Three cases of congenital Cytomegalovirus (CMV) infection were perinatally managed in Hokkaido University Hospital. In case 1, prenatal CT and MRI revealed dilation of ventlicles and calcification in the peliventriculararea. A male infant weighing 3,020g was born at 39 weeks of gestation (GW). He is 9 years old and has a severe hearing problem. In case 2, by prenatal ultrasound examinations, IUGR, dilation of ventricles, and hepatosplenomegaly were detected. A male infant weighing 1,800g was born at 38 GW, and died at 5 months after birth. Fetal ascites was first detected at 25 GW in case 3. Immunoglobulin (2.5g) was directly infused in to the fetal peritoneal cavity at 28 and 29 GW. At 34 GW, a male infant weighing 2,340g was born by cesarean section due to fetal distress. CMV DNA detected by PCR turned negative in neonatal ascites. He is 1 year old and has noneurological abnormality. Direct fetal infusion of immunoglobulin may be beneficial in treating congenital CMV infection.

    本研究では、aβ2GPI/HLA class Ⅱ測定法の不育症の原因検索や重症度診断における有用性を明らかする。また、HLA class Ⅱの新しい機能を応用し、不育症を引き起こす未知の抗原を探索する。ミスフォールド蛋白/HLA class Ⅱ複合体に対する自己抗体の新検出法が、抗リン脂質抗体症候群(APS)の診断や不育症の原因精査に有用かを調べる。この複合体抗体に起因する不育症の新たな治療法を開発し確立することを目的とする。また、検査法の標準化と汎用化のために、ELISAプレートやビーズを用いた測定法を新たに開発する。 今年度の研究実績を下に記す。 目的:不育症患者のaβ2GPI/HLA-DR7複合体(ネオ・セルフ)抗体と不育症との関係を明らかにすることを目的とした。対象と方法:2回以上の流産ないし1回以上の死産の既往がある不育症女性227人を対象とした。流死産歴無し、生産歴あり、抗リン脂質抗体(aPL)陰性、自己免疫疾患無しの女性208人をコントロールとした。コントロール女性の血清の99%ile を基準値として、対象でaβ2GPI/HLA-DR7抗体価を測定した。結果:52.6 U/mlが基準値となった。不育症女性227人中、52人(22.9%)が、aβ2GPI/HLA-DR7抗体陽性であった。不育症の原因/リスク因子が不明の121人中24人(19.8%)で、またAPS症状があるが基準aPLが陰性の114人中22人(19.3%)において、aβ2GPI/HLA-DR7抗体が陽性であることが初めて明らかになった。結論:これまで原因/リスク因子不明とされていた不育症女性の19.8%で陽性になったことから、aβ2GPI/HLA-DR7複合体抗体は、新たな不育症の原因である可能性が示された。前向きコホート研究や介入研究の臨床試験によって、因果関係の決定が今後期待される。Arthritis & Rheumatologyに投稿、リバイス中である。

    末梢血ではCD94陽性NK細胞およびBreg細胞中のCD43+CD27high B細胞の割合が不育症患者で増加する傾向を認めた。また、染色体正常流産脱落膜ではマクロファージのうちM1が増加する一方、M2の増加がみられず、M2への分化が初期の妊娠維持に好ましいことが明らかとなった。また、末梢血においてはNK細胞のCD44発現には変化はないものの、CD44陽性子宮NK細胞が染色体正常流産脱落膜で増加する傾向にあった。NK細胞上のCD44発現量については、末梢血による発現よりも脱落膜での発現が流産と関連する可能性があり、非妊時の末梢血よりも脱落膜に存在するNK細胞が重要であると考えられる。

    子宮内膜における月経周期および発がん過程に関する、PITX1遺伝子によるテロメレース制御機構について検討した。PITX1蛋白は、子宮体がん低分化症例の腫瘍部において発現を認めるものの、90%以上の体がん組織において発現を認めず、子宮体がんにおけるテロメレース高発現に関与している可能性が示唆された。一方、正常内膜腺にPITX1発現が明らかとなった。しかし、月経周期との関連、正常内膜から増殖症をへて体がんに至る段階については、明確な関連性を見出すことはできなかった。病理組織学的因子、予後、Ki-67,ERα,PR発現との関連を含め、解析対象となるデータが多岐にわたるため、今後も解析を継続する。
