RESUMO
BACKGROUND: The effect of velamentous cord insertion (VCI) on perinatal outcomes in twin pregnancies is unclear due to conflicting findings. This retrospective study aimed to examine VCI prevalence and related risk factors in twin pregnancies and its association with adverse perinatal outcomes. METHODS: Women with twin pregnancies who delivered between January 2012 and December 2021 in a single tertiary hospital were included. The participants were divided into dichorionic (DC) and monochorionic diamniotic (MCDA) groups, and their maternal and fetal characteristics and VCI rates were compared. Logistic regression models were used to identify risk factors for VCI and VCI-related perinatal outcomes. RESULTS: Among the 694 twin pregnancies included in this study, the VCI rate was significantly higher in MCDA than in DC twins. Body mass index and MCDA twins were significant risk factors for VCI, whereas assisted reproductive technology pregnancy was a significant protective factor against VCI. In DC twins, VCI did not affect perinatal outcomes. In MCDA twins, VCI was a significant risk factor for fetal growth restriction, twin-to-twin transfusion syndrome, and preterm birth at <36 weeks. CONCLUSIONS: VCI was a prominent risk factor for adverse perinatal outcomes only in MCDA twins. Antenatal sonographic assessment of the umbilical cord insertion site would be beneficial.
RESUMO
PURPOSE: To assess the impact of the interpregnancy interval (IPI) after cesarean delivery on the risks of adverse perinatal events during subsequent pregnancies. METHODS: We retrospectively examined perinatal outcomes of subsequent pregnancies of women whose most recent birth experience involved cesarean delivery at our hospital between January 2014 and December 2019. IPI was defined as the time between live birth and subsequent conception. Three IPI groups: < 18 months, 18-60 months, and > 60 months, were assessed. The risks of preterm birth, preeclampsia, placenta previa, placental abruption, fetal growth restriction, and successful vaginal birth were compared among the three IPI groups using uni- and multivariate analyses. RESULTS: We registered 592 births after cesarean delivery: 178, 288, and 126 in the IPI < 18 months, 18-60 months, and > 60 months groups, respectively. The groups did not differ significantly regarding perinatal outcomes. The multivariate analysis revealed no significant differences in the risks of adverse perinatal outcomes among all groups. The odds ratios (ORs) for preterm birth at < 37 weeks of gestation were 1.24 and 1.64 for those in the < 18 months and > 60 months groups, respectively (P = 0.362 and P = 0.055, respectively). The groups did not differ significantly regarding vaginal birth success rate (ORs 1.72 for the < 18 months group, 0.49 for the > 60 months group; P = 0.486 and P = 0.446, respectively). CONCLUSION: After cesarean delivery, IPIs shorter than 18 months and longer than 60 months do not significantly impact the risks of adverse perinatal outcomes or successful vaginal birth compared with IPIs of 18-60 months.

This study aimed to evaluate the differences in the impact on maternal renal function between singleton and twin pregnancies in the second half of pregnancy. It retrospectively enrolled 1711 pregnant women consisting of 1547 singleton pregnancies and 164 twin pregnancies from Japanese Red Cross Aichi Medical Center Nagoya Daiichi Hospital from January 2019 to June 2021. Patients underwent renal function tests (serum blood urea nitrogen, creatinine, and estimated glomerular filtration rate (eGFR)) at least one month before delivery. The main outcome measure was maternal renal dysfunction, defined as a serum creatinine level above 0.8 mg/dL. The serum creatinine level was significantly higher and the eGFR was significantly lower in twin than in singleton pregnancies (p < 0.001). In addition, the rate of renal dysfunction was significantly higher in twin than in singleton pregnancies (7.9% vs. 2.6%; p < 0.01). Multivariate analysis revealed that twin pregnancy (odds ratio (OR) 3.38), nulliparity (OR 2.31), and preeclampsia (OR 3.64) were significant risk factors for maternal renal dysfunction. Maternal renal dysfunction was observed in 13 twin pregnancies, all of which recovered to within normal limits during the early months of the postpartum period. Twin pregnancy is a significant risk factor for maternal renal dysfunction; renal function should be carefully monitored in twin pregnancies.
RESUMO
OBJECTIVES: We compared the pregnancy prolongation effect attributable to cervical cerclage to that achieved by conservative management, and determined the cervical length for which cervical cerclage is effective. METHODS: We retrospectively examined medical records of 281 women admitted to our hospital between January 2013 and December 2017 for management of threatened preterm birth at 22-28 weeks of gestation. Obstetricians determined suitability for cervical cerclage, which was performed using the McDonald procedure in all cases. Of the 281 subjects, 71 underwent cervical cerclage (cerclage group); the other 210 received conservative therapy (non-cerclage group). We recorded maternal and neonatal characteristics of all patients. The two groups were compared in terms of length of extension of pregnancy and weeks of gestation at delivery. Multivariate analysis was performed to identify factors associated with extension of time to delivery. RESULTS: Our analyses revealed that the cerclage group was hospitalized earlier in pregnancy than the non-cerclage group (23.7 ± 1.5 weeks vs. 26.4 ± 1.9 weeks, p < .001) and had shorter cervixes (6.0 ± 9.4 mm vs. 16.9 ± 13.0 mm, p < .001). The two groups did not differ significantly in terms of gestational weeks at delivery. Multivariate analysis regarding extension of pregnancy revealed significant differences in extension of pregnancy related with cervical cerclage (26.65 days, 95% CI 17.0 - 36.3, p < .001) and cervical length <10 mm (-27.4 days, 95% CI -36.0--18.8, p < .001). While the time to delivery was extended by cervical cerclage in women with short cervixes (<25 mm), the two groups did not differ when cervical length was ≥15 mm. CONCLUSIONS: Cervical cerclage was a significant positive factor and short cervix was a significant negative factor for elongating pregnancy. In primigravida and multigravida women with no history of preterm birth, when the cervix is short (<10 mm), cervical cerclage should be recommended.

OBJECTIVE: The aim of this study was to examine the risk factors for antepartum hemorrhage (APH) in women with placenta previa. METHODS: In this retrospective cohort study, we analyzed the medical records of 233 women with singleton pregnancies presenting with placenta previa whose deliveries were performed at our hospital between January 2009 and July 2018. RESULTS: Of the 233 women included in this study, 130 (55.8%) had APH. In the APH group, the gestational age and neonatal birth weight were significantly lower compared with the no hemorrhage group. Maternal age <30 years and multiparity were identified as significant risk factors for APH in both the univariate and multivariate analyses. Focusing on the previous route of delivery in multiparous women, the risk of APH was significantly higher in multiparous women who had experienced at least one vaginal delivery compared with nulliparous women (adjusted odds ratio (OR): 3.42 [95% confidence interval: 1.83-6.38]). CONCLUSION: We showed that women with placenta previa who were under 30 years old and who had a history of vaginal delivery may be at significant risk of experiencing APH.

OBJECTIVE: This study aimed to evaluate the success rate of vaginal delivery, the reasons for unplanned caesarean delivery, the rate of umbilical cord prolapse and the risk of umbilical cord prolapse in twin deliveries. DESIGN: Retrospective cohort study. SETTING: Single institution. PARTICIPANTS: This study included 455 women pregnant with twins (307 dichorionic and 148 monochorionic) who attempted vaginal delivery from January 2009 to August 2018. The following criteria were considered for vaginal delivery: diamniotic twins, cephalic presentation of the first twin, no history of uterine scar, no other indications for caesarean delivery, no major structural abnormality in either twin and no fetal aneuploidy. RESULTS: The rate of vaginal delivery of both twins was 89.5% (407 of 455), caesarean delivery of both twins was 7.7% (35 of 455) and caesarean delivery of only the second twin was 2.9% (13 of 455). The major reasons for unplanned caesarean delivery were arrest of labour and non-reassuring fetal heart rate pattern. The rate of umbilical cord prolapse in the second twin was 1.8% (8 of 455). Multivariate analysis revealed that abnormal umbilical cord insertion in the second twin (velamentous or marginal) was the only significant factor for umbilical cord prolapse in the second twin (OR, 5.05, 95% CI 1.139 to 22.472, p=0.033). CONCLUSIONS: Abnormal umbilical cord insertion in the second twin (velamentous or marginal) was a significant factor for umbilical cord prolapse during delivery. Antenatal assessment of the second twin's umbilical cord insertion using ultrasonography would be beneficial.

BACKGROUND: There are few studies developing a scoring system for short-term survival of patients with gynecologic malignancy. METHODS: Seventy-three terminally ill patients with gynecologic malignancy who were admitted to our palliative care unit (PCU) from June 2009 to February 2018 were included. We accumulated routine blood data within 3 months before PCU discharge. Receiver-operating characteristic analysis was performed on each blood factor, and area under the curve (AUC) was calculated to determine the predictive value for 14-day survival after the blood test. Multivariable logistic regression analysis was performed to identify significant independent prognostic factors of 14-day mortality. To develop a scoring system for 14-day mortality, laboratory prognostic score for gynecologic malignancy (G-LPS) was calculated using the sum of indices of the independent prognostic factors. RESULTS: Multivariable analysis showed that 6 of 24 indices, namely, C-reactive protein ≥ 13.3 mg/dL, total bilirubin ≥ 1.1 mg/dL, sodium < 131 mEq/L, blood urea nitrogen ≥ 28 mg/dL, white blood cell count ≥ 17.7 × 103/µL, and eosinophil level < 0.2%, were significant independent factors of 14-day survival. G-LPS was obtained from the sum of the six indices. The AUC was 0.7977 at the optimal cut-off value of G-LPS 3. G-LPS 3 predicted death within 14 days with a sensitivity of 72% and a specificity of 79%. CONCLUSIONS: Six of the 24 laboratory indices were identified as independent prognostic factors of 14-day mortality in terminally ill patients with gynecologic malignancy. G-LPS showed acceptable ability of predicting 14-day survival.

Objective: We examined the impact of the abruption severity and the onset-to-delivery time on the maternal and neonatal outcomes of cases of clinically diagnosed placental abruption (PA).Material and methods: We investigated 84 patients who were diagnosed with PA at our hospital from January 2009 to September 2017. We classified the patients with PA into three groups based on the extent of the abruption: (1) mild abruption, <20%; (2) moderate abruption, 20-49%; (3) severe abruption, ≥50%, which was defined by the attending obstetricians at the time of delivery. The neonatal outcome was measured by the umbilical artery pH and the maternal outcome was measured by the obstetric disseminated intravascular coagulation score (DIC score).Results: The rate of hypertensive disorders of pregnancy in the moderate abruption group was significantly lower than that in other groups (p = .010). The umbilical artery pH was below 7.00 in 29 cases. The umbilical artery pH of the severe abruption group (6.92) was the lowest and was significantly lower in comparison to other groups (mild group [7.24], p < .001; moderate group [7.11], p < .05). There was a significant correlation between the onset-to-delivery time and the umbilical artery pH in the moderate group (R = -0.43). The maternal DIC scores in the three groups did not differ to a statistically significant extent.Conclusions: The severity of placental separation is significantly correlated with poor neonatal outcomes and there was a significant negative correlation between the onset-to-delivery time and the umbilical artery pH in moderate abruption.

BACKGROUND: The aim of this study was to investigate how much the risks of recurrence and death are increased as a consequence of selecting fertility-sparing surgery (FSS) in young women with epithelial ovarian cancer (EOC). METHODS: After a central pathological review and search of the medical records from 14 collaborating hospitals, a non-randomized, observational cohort study was conducted between 1987 and 2015, including 1183 women with stage I EOC. Finally, a total of 285 patients with stage I EOC at reproductive age were recruited. Oncologic outcomes were compared between the FSS (N = 101) and radical surgery (RS) group (N = 184) using a propensity score (PS)-matching technique to adjust for relevant risk factors: the age, substage, histological type, grade, CA125 values, ascites cytology, ascites volume, and chemotherapy. RESULTS: During 66.0 months (median) of follow-up, 42 patients (14.7%) developed recurrence, and 31 patients (10.9%) died. In the original cohort, there was no significant difference in overall survival (OS) or recurrence-free survival (RFS) between the FSS and RS groups {Log-rank: OS (P = 0.838), RFS (P = 0.377)}. In the PS-matched cohort after adjustment for multiple clinicopathologic factors, there was no significant difference in RFS or OS between the FSS and RS groups {RFS (FSS vs. RS), HR: 1.262 (95% CI: 0.559-2.852), P = 0. 575; OS (FSS vs. RS), HR: 1.206 (95% CI: 0.460-3.163), P = 0.704}. CONCLUSIONS: After adjustment for clinicopathologic factors, FSS in itself may not worsen the oncologic outcome in young women with early-stage EOC. A large-scale clinical study is necessary to validate the findings.

Malignant ovarian neoplasm is one of the most lethal malignancies among cancers of the female reproductive system. Occasionally, these tumors originate from non-ovarian organs as metastatic lesions since the ovary is a frequent metastatic target of many cancers. However, there limited clinical information on metastatic ovarian carcinoma (MOC) and its hallmarks are unknown. During the period of 1986-2015, 4,284 patients with malignant ovarian neoplasm were identified using the Tokai Ovarian Tumor Study Group (TOTSG) database. Of these, excluding borderline malignant tumor, 3,478 patients with malignant ovarian cancer were extracted. The pathological slides were evaluated under central pathological review. Among them, a total of 143 (4.1%) patients with MOC were identified. The median age of patients with MOC was 54 (29-82) years. The most and second most frequent original tumors were colorectal (43%, N=62) and gastric (29%, N=42) carcinoma, respectively. The rates of carcinoma of the appendix, breast, and pancreas were 8, 6, and 4%, respectively. This is the one of the largest studies clarifying the rates of MOC among malignant ovarian neoplasms. Although the rate is low, we should keep in mind that MOC, particularly from colorectal and gastric cancer should be considered when encountering clinical practice of ovarian cancer.

The objective of this study was to estimate the frequency of possible occult metastasis through long-term survival analyses in patients with clear cell carcinoma (CCC) who had undergone complete resection. During the period of 1990-2015, 799 patients with stage I-IV CCC were identified in the TOTSG database. Of these, a total of 528 patients without a residual tumor were enrolled in the study and classified into four groups: Group 1: FIGO stage IA-IB (N=104), Group 2: FIGO stage IC1 (N=170), Group 3: FIGO stage IC2/IC3 (N=98), and Group 4: FIGO stage II-III (no residual tumor: N=156). Cumulative incidences of recurrence (CIR) and death (CID) were examined. The median age was 54, ranging from 29-87. The 5-year CIR / CID of each group were as follows: Group 1 (7.3% / 3.8%), Group 2 (14.3% / 10.2%), Group 3 (37.7% / 18.4%), and Group 4 (46.5% / 33.8%), respectively {P<0.0001 (recurrence) / P<0.0001 (death)}. Furthermore, confining analysis to relapsed patients, 1-, 2-, and 3-year CID after recurrence were 41.5, 60.9, and 73.9, respectively. Confining analyses to patients with sufficient information about adjuvant chemotherapy, the 5-year CIR / CID of stage IA-IC1 patients with or without chemotherapy were as follows: recurrence {13.0% (yes) / 9.6% (no)}, death {9.3% (yes) / 4.2% (no)}, respectively {P=0.947 (CIR) / P=0.224 (CID)}. CCC patients staged greater than IC2/ IC3 show a marked risk of mortality, even after complete surgical resection.
RESUMO
Management and treatment of stage I B1 cervical cancer during pregnancy depends on the estimated gestational age and personal desires. We report 4 cases of stage I B1 cervical cancer during pregnancy that were treated differently. Case 1: A 29- year-old woman, primipara, visited our hospital at 7 weeks' gestation. She was diagnosed with a stage I B1 cervical cancer by using conization at 12 weeks' gestation. She strongly desired childbirth and therefore was treated at 29 weeks' gestation with a simultaneous cesarean section and radical surgery. Case 2: A 26-year-old woman, para 1, was diagnosed with stage I B1 cervical cancer at 23 weeks' gestation. She was treated at 28 weeks' gestation with a simultaneous cesarean section and radical surgery. Case 3: A 36-year-old woman, para 7, at 18 weeks' gestation, visited our hospital because of a stage I A cervical cancer. She chose to undergo abortion and radical surgery, which were performed simultaneously at 21 weeks' gestation. After the surgery, she was diagnosed with a stage I B1 cervical cancer pathologically. Case 4: A 33-year-old woman, para 2, was diagnosed with a stage I B2 cervical cancer at 30 weeks' gestation and was treated with a simultaneous cesarean section and radical surgery at 31 weeks' gestation.

AIM: To assess whether FOXL2 p.C134W mutation may play a role in the development of human ovarian tumors in the Japanese, we investigated the FOXL2 codon 134 mutation and protein expression of inhibin-α, bone morphogenetic protein 2 (BMP2) and follistatin (FST) in Japanese patients with granulosa cell tumor (GCT) of the ovary and other ovarian tumors. METHODS: We analyzed 114 tumor tissues from ovarian tumors, including 44 adult-type and two juvenile-type GCT of the ovary and 68 ovarian tumors by DNA sequencing. Immunohistochemistry was also performed in the adult and juvenile GCT tissues by immunostaining inhibin-α, BMP2 and FST. RESULTS: We found the FOXL2 p.C134W mutation in 27 out of 44 (61.4%) adult-type GCT of the ovary, but none in other ovarian tumors. Histologically, all of the adult-type GCT sections were positive for inhibin-α, and the expression of BMP2 and FST was detected in 14 of 44 (31.8%) and zero of 47 (0%), respectively. No significant differences regarding the diagnosed age, preoperative serum carbohydrate antigen 125 levels, or BMP2 immunopositivity between the FOXL2 p.C134W mutation-positive and mutation-negative were found in the adult-type GCT patients. CONCLUSION: Our findings suggest that FOXL2 p.C134W mutation-positive adult-type GCT of the ovary may not be common in the Japanese as compared to the previous data.

The best treatment for recurrent granulosa cell tumor(GCT)is considered to be surgical resection, because the effects of chemotherapy or radiation on GCT are obscure. The common site of recurrence is the pelvic cavity, including the surface of the liver and intestine as tumor-dissemination-patterns. Between June 1988 and June 2011, we treated 15 patients with GCT at our hospital. The median follow-up time was 56(22-286)months. Ten patients were stage I, 3 were stage II, and 2 were stage III. No patients had residual lesions at the primary surgery area. Six patients have recurred, and the median disease free survival(DFS)was 85(15-128)months. Six patients had relapses in the pelvic cavity, 2 in the retroperitneal lymph nodes, and 1 in the upper abdomen. Two patients relapsed more than twice; however, the rapid detection of recurrence and surgical resection have kept all patients alive. Thirteen patients have no evidence of disease(NED), 2 are alive with disease(AWD), and no one has died of the disease(DOD). We suggest that maximal debulking surgery to achieve complete cytoreduction of recurrent GCT is the most important treatment for prolonging survival.

BACKGROUND: It is controversial whether patients with stage I ovarian clear cell carcinoma (CCC) benefit from postoperative chemotherapy. This study was designed to evaluate the postoperative outcomes associated with the inclusion or exclusion of adjuvant therapy in these patients. METHODS: A total of 185 patients who were treated for stage I CCC between 1991 and 2007 were retrospectively evaluated. All of the patients had received comprehensive surgical staging, and their condition had been diagnosed by a central pathological review system. Only one patient with stage IB was excluded from this study. RESULTS: Median follow-up time was 62 months (range 7-191 months). Median age was 52 years (30-75 years). There were 41, 93, and 50 patients in stage IA, intraoperative capsule ruptured IC (rupture-IC), and all other-IC groups, respectively. The 5-year recurrence-free survival rates for the substage were 97.6%, 87.8%, and 70.4% (P < 0.001), respectively. Among 134 patients consisting of those in the stage IA and rupture-IC groups, 91 patients received adjuvant chemotherapy (AC) and 43 patients did not (non-AC). There was no significant survival difference in each substage group between the non-AC and AC groups in 5-year recurrence-free survival rate (stage IA, 100% vs 93.8%; rupture-IC, 94.1% vs 86.6%). Multivariate analysis demonstrated that there was no significant prognostic factor for both recurrence and survival among the IA and rupture-IC groups. Postoperative therapy, regimen, and chemotherapy cycles were not significantly affected. CONCLUSIONS: This study indicates that adjuvant chemotherapy does not contribute to the improving prognosis of stage IA ovarian CCC. Whereas the histological type is CCC, the routine adjuvant chemotherapy after comprehensive surgical staging may be unnecessary for patients with at least stage IA.

OBJECTIVE: We analyzed a large number of stage I clear cell carcinoma of the ovary (CCC) patients to estimate the survival impact of the capsule status in stage I CCC patients, particularly in comparison with non-CCC patients. METHODS: Clinicopathologic data on 564 patients with stage I epithelial ovarian cancer (EOC) collected under the central pathological review system were subjected to uni- and multivariable analyses to evaluate the disease-free survival (DFS) and overall survival (OS). RESULTS: There was no significant difference in both the OS and DFS of CCC patients between IA and IC(ir) (intraoperative capsule rupture) {IA vs. IC(ir); OS: P=0.1402, DFS: P=0.2701}. In contrast, CCC patients at IC(non-ir) {IC excluding for IC(ir), such as preoperative capsule rupture, positive ascites/washing, and surface involvement} showed a poorer OS and DFS than those at IC(ir), or those at the corresponding stage in non-CCC. In multivariable analysis, the capsule status was an independent prognostic factor of a poor OS and DFS {OS: HR, 2.832; 95% CI 1.156-6.938; P=0.023; DFS: HR, 4.327; 95% CI, 1.937-9.667; P=0.0004)} {In contrast, non-CCC: N.S. (OS/DFS)}. Furthermore, in CCC patients, intraperitoneal recurrences were more frequently observed in IC(non-ir) CCC than IA or IC(ir) CCC (P=0.0083) {In contrast, non-CCC: N.S.}. CONCLUSION: This study suggests that CCC patients other than those with intraoperative capsule rupture show a considerable risk for mortality despite adjuvant chemotherapy.

OBJECTIVES: The purpose of this study was to clarify the clinical outcome of patients with stage IA mucinous epithelial ovarian cancer (mEOC) treated with fertility-sparing surgery (FSS). METHODS: After a central pathological review and search of the medical records from multiple institutions, a total of 148 stage I mEOC patients were retrospectively evaluated in the current study. All mEOC patients were divided into three groups: group A (FSS; age, 40≥); groups B and C {radical surgery; age, 40≥ (B); 40< (C)}. Survival analysis was performed among these three groups using Kaplan-Meier methods. RESULTS: The median follow-up time of all mEOC patients was 71.6 (4.8-448.3) months. Among the 41 patients in group A, 27 patients (65.9%) had IA disease, and 14 (34.1%) had IC disease. Five-year overall survival (OS) and disease-free survival (DFS) rates of patients in the groups were as follows: group A, 97.3% (OS)/90.5% (DFS); group B, 94.4% (OS)/94.4% (DFS); group C; 97.3% (OS)/89.3% (DFS). Collectively, there was no significant difference in OS or DFS among these groups even though they were stratified to each substage (IA/IC) (OS, P=0.180; DFS, P=0.445, respectively). Furthermore, in multivariate analyses, the surgical procedure was not an independent prognostic factor for either OS or DFS (OS, HR: 0.340, 95% CI: 0.034-3.775, P=0.352; DFS, HR: 0.660, 95% CI: 0.142-3.070, P=0.596). CONCLUSIONS: Patients with stage I mEOC treated with FSS did not necessarily show a poorer prognosis than those receiving radical surgery.

BACKGROUND: Residual tumor size after primary surgery is the most important prognostic factor in advanced ovarian cancer. We conducted a retrospective study in Japanese women to evaluate the association of various residual disease diameters and histological subtypes with overall survival (OS) in patients with residual disease ≥1 cm. METHODS: Demographic and clinicopathological data were obtained from the Tokai Ovarian Tumor Study Group; 294 patients with International Federation of Gynecology and Obstetrics stage III and IV epithelial ovarian carcinoma who had undergone primary debulking surgery between 1986 and 2007 and had ≥1 cm residual tumor were identified. A Cox proportional hazards model was used to assess the association of prognostic factors with OS. RESULTS: Non-serous advanced ovarian cancer was associated with a significant increase in the risk of death. For serous ovarian cancer, residual tumor size was not an independent prognostic factor [multivariate hazard ratio (HR) = 1.63, 95% confidence interval (CI) = 0.96-2.79 (2-5 cm); HR = 1.25, 95% CI = 0.72-2.17 (>5 cm); trend P = 0.480], whereas taxane-based chemotherapy was associated with a better prognosis (HR = 0.66, 95% CI = 0.44-0.99, P = 0.046). For non-serous ovarian cancer, in contrast, residual tumor size was associated with an increased risk of death [multivariate HR = 0.87, 95% CI = 0.36-2.14 (2-5 cm); HR = 2.21, 95% CI = 0.96-5.08 (>5 cm); trend P = 0.067], whereas taxane-based chemotherapy was not a prognostic factor [HR = 0.70, 95% CI = 0.29-1.65, P = 0.409 (taxane-based)]. CONCLUSIONS: Although primary maximal cytoreduction is essential to improving OS in advanced ovarian cancer, our findings suggest the management of patients with suboptimal residual tumor should take into account differences between histological subtypes.

We investigated the results of cervical cytology, pathology of colposcopic biopsy and surgical specimen among 765 women suspected to have cervical intraepithelial neoplasia (CIN). Significantly more patients with cervical cytology class III b than class III a were diagnosed in CIN grade 3 on colposcopic biopsy. The concordance rate of colposcopic biopsy and surgical specimen was 79.8%, but we preoperatively diagnosed CIN grade 3 or more at 96.1% with colposcopic biopsy. In time course observation, CIN regressed in 26.3% of all patients, progressed in 19.3% and did not change in 54.4%. Many patients of CIN grade 2 progressed to grade 3 in two years. Significantly more patients of CIN grade 1 or 2 with cervical cytology class III b progressed than with class III a (p<0.05).

BACKGROUND: In epithelial ovarian cancer (EOC), fertility-sparing surgery (FSS) has mainly been chosen for stage IA disease. The purpose of this study was to clarify the clinical outcome of patients with clear-cell carcinoma of the ovary (CCC) who would usually undergo radical surgery. CASES: After a central pathological review and search of the medical records from multiple institutions between 1988 and 2005, a total of 10 CCC patients treated with FSS were retrospectively evaluated in the current study. The mean age was 35.9 years (range: 32-39 years). The median follow-up time was 35.4 months (range: 21.7-153.2 months). The stage was IA in 4 patients, and IC in 6 patients [IC(b) in 5 patients, and IC(2) in one]. Nine patients received adjuvant chemotherapy. Nine patients were alive and one patient with stage IC(2) died of the disease at a follow-up time of 36.8 months. Five pregnancies were observed in 4 patients. CONCLUSIONS: Although there is no worldwide criterion for FSS in CCC patients at present, it seems that, in selected patients, this surgical approach could be adopted. This should be investigated by additional studies in a larger series.
