6. Survival Outcomes of Ovarian-Sparing Surgery for Early-Stage Adult Granulosa Cell Tumor.
PMID:日期:2026-10-02Evidence regarding the oncologic safety of ovarian-preserving surgery for the management of early-stage adult granulosa cell tumors remains limited and inconsistent. To examine overall survival among premenopausal patients with early-stage adult granulosa cell tumors undergoing ovarian-sparing surgery (cystectomy or unilateral salpingo-oophorectomy), in comparison to bilateral salpingo-oophorectomy. This retrospective cohort study utilized the National Cancer Database to identify female patients aged 18-49 years with histologically confirmed stage IA or IC adult granulosa cell tumors diagnosed between 2004 and 2021. Patients were categorized by surgical approach: ovarian cystectomy, unilateral salpingo-oophorectomy or bilateral salpingo-oophorectomy. Propensity score-based inverse probability of treatment weighting was used to account for differences in baseline patient characteristics across the surgical groups. Two- and five-year overall survival was estimated based on Kaplan-Meier methods after applying inverse probability of treatment weighting. The association between surgical group and survival was estimated using Cox proportional hazards regression with inverse probability of treatment weighting and adjustment for treatment factors (hysterectomy, lymphadenectomy, and chemotherapy). Of 851 patients identified, 76 (8.9%) underwent cystectomy, 445 (52.3%) underwent unilateral salpingo-oophorectomy and 330 (38.8%) underwent bilateral salpingo-oophorectomy. Concurrent hysterectomy was performed in 82.7% of the bilateral salpingo-oophorectomy group, compared with 22.9% of the unilateral salpingo-oophorectomy group. Younger patients (aged 18-39) more frequently underwent ovarian-sparing procedures, while those aged 40-49 more frequently underwent bilateral salpingo-oophorectomy (P < .001). Median follow-up was 77.5 months (interquartile range: 39.2-135.8). After inverse probability of treatment weighting and adjustment for treatment factors, there was no significant difference in overall survival across the surgical groups (adjusted hazard ratio [95% confidence interval]: 0.72 [0.23-2.28] for cystectomy versus bilateral salpingo-oophorectomy and 1.06 [0.53-2.15] for unilateral salpingo-oophorectomy versus bilateral salpingo-oophorectomy). Findings remained consistent when the analysis was stratified by age (18-39 and 40-49 years) and stage (IA and IC). Among patients aged 18-49 with early-stage adult granulosa cell tumors, ovarian-preserving surgery (cystectomy or unilateral salpingo-oophorectomy) was associated with overall survival comparable to bilateral salpingo-oophorectomy. Further research comparing recurrence and disease-free survival across these surgical groups is needed to facilitate clinical decision-making.

8. Transcervical Balloon Cervical Ripening and Risk of Uterine Rupture After Previous Cesarean Delivery: A Systematic Review and Meta-analysis.
8. 经宫颈球囊促宫颈成熟与既往剖宫产术后子宫破裂风险：一项系统评价和荟萃分析PMID:日期:2026-09-29To estimate comparator-specific associations between transcervical balloon cervical ripening and complete uterine rupture during trial of labor after cesarean. PubMed/MEDLINE, Embase, CINAHL, Cochrane CENTRAL, Web of Science, and Google Scholar were searched from inception through June 2026 without language restriction, plus reference lists and trial registries (PROSPERO CRD420261444368). Studies of trial of labor after a previous low-transverse cesarean delivery that used a Foley, single-balloon, or double-balloon catheter for cervical ripening were included. Comparative observational studies with spontaneous labor, oxytocin, or prostaglandins as comparators were included in the quantitative synthesis. Amniotomy alone was a prespecified eligible comparator; however, no study reported a separable amniotomy-only arm, precluding quantitative pooling of this comparison. Single-arm cohorts were summarized descriptively, while randomized trials were synthesized qualitatively. Primary analyses were restricted to studies reporting complete uterine rupture separately. Because balloon placement was followed by amniotomy, oxytocin, or both in nearly every protocol, the exposure is designated a balloon-based induction strategy rather than the catheter in isolation. Risk of bias was assessed with ROBINS-I, the Newcastle-Ottawa Scale, and Cochrane RoB 2; certainty was rated with GRADE. Comparator-specific odds ratios (ORs) and absolute risk differences were estimated with Mantel-Haenszel methods, with Peto and DerSimonian-Laird models as sensitivity analyses; potentially overlapping Swedish cohorts were not pooled. Eighteen nonrandomized studies and two randomized trials contributed 28,035 study observations, including 5,516 balloon exposures. Relative to prostaglandin induction, balloon ripening showed lower odds of complete uterine rupture across three cohorts (Mantel-Haenszel OR, 0.43; 95% confidence interval [CI], 0.26-0.72; risk difference, -19 per 1,000 [95% CI, -31 to -7] across four cohorts); a potentially overlapping Swedish cohort and a cohort reporting a combined rupture/dehiscence endpoint gave concordant estimates, and one trial recorded no ruptures. No difference was detected versus oxytocin alone (OR, 0.24; 95% CI, 0.05-1.18) or spontaneous labor (seven cohorts; OR, 1.29; 95% CI, 0.90-1.84; OR, 1.09 [95% CI, 0.73-1.62] excluding the most influential cohort). Across all pharmacologic comparators the OR was 0.40 (95% CI, 0.25-0.66), whereas dehiscence was reported more often after balloon-based induction (five studies; OR, 1.86; 95% CI, 1.06-3.29), with concordant estimates against oxytocin-based induction (OR, 1.80; 95% CI, 0.83-3.92), spontaneous labor (OR, 2.24; 95% CI, 0.91-5.52), and prostaglandins (OR, 1.09; 95% CI, 0.15-7.84; P = .80 for subgroup difference). Certainty was very low throughout. A balloon-based induction strategy was not associated with an increase in complete uterine rupture compared with spontaneous labor or oxytocin alone and showed lower odds than prostaglandin induction. Because amniotomy, oxytocin, or both almost always followed catheter placement, these estimates cannot be attributed to the catheter alone. Mechanical ripening therefore remains reasonable in carefully selected candidates when induction is indicated, with counseling, continuous monitoring, and immediate access to emergency cesarean delivery.

9. Selective Reduction in Monochorionic Pregnancies With Selective Fetal Growth Restriction: A Systematic Review and Meta-analysis.
9. 选择性胎儿生长受限的单绒毛膜妊娠中的选择性减胎：系统评价与荟萃分析PMID:日期:2026-09-29To estimate the rates of co-twin intrauterine fetal demise (IUFD), co-twin neonatal demise, and gestational age (GA) at delivery in monochorionic (MC) pregnancies complicated by selective fetal growth restriction (sFGR) undergoing selective reduction (SR) and stratify the outcomes according to the surgical technique. PubMed, Embase, Cochrane Library, Scopus, and Web of Science were searched from inception through May 2026. Studies were eligible if they reported MC pregnancies complicated by sFGR undergoing SR with data on co-twin IUFD or neonatal demise and GA at delivery. This systematic review and meta-analysis was conducted per PRISMA guidelines and registered on INPLASY (INPLASY202580001). Pooled estimates were calculated using random-effects meta-analysis, and technique differences were evaluated using meta-analytic tests for subgroup differences. Post hoc binomial generalized linear mixed models (GLMMs) assessed the robustness of dichotomous outcomes without continuity correction. I quantified heterogeneity across studies. A total of 22 studies, including 686 pregnancies, met the inclusion criteria and were eligible for quantitative synthesis. The overall rates of co-twin IUFD and co-twin neonatal death were 15% and 4%, respectively, and the GA at delivery was 35.4 weeks (95% CI, 34.2-36.6). In the primary indirect study-level subgroup analysis, pooled co-twin IUFD was higher in RFA than BCC studies (20% vs 9%; P=0.02). In the GLMM sensitivity analysis, the estimated rates remained higher in RFA than BCC studies (14.8% vs 6.6%), but the subgroup difference was not statistically significant (P=0.06). The only direct within-study comparison included 24 sFGR pregnancies and showed no significant difference in co-twin IUFD (BCC, 0/5; RFA, 3/19; P=1.00). Co-twin neonatal death rates were comparable (BCC, 5% vs RFA, 3%). GA at delivery was lower in cases undergoing BCC compared with RFA (34.5 weeks vs 36.8 weeks, respectively; P=0.039). These unadjusted comparisons may be confounded by differences in study and case characteristics. In MC pregnancies complicated by sFGR undergoing SR, pooled risks of co-twin IUFD and neonatal death were approximately 15% and 4%, respectively. The primary analysis suggested lower co-twin IUFD and earlier delivery in BCC than RFA studies; however, the IUFD difference was not statistically significant in the GLMM sensitivity analysis, and all technique comparisons were indirect, unadjusted, potentially confounded , and the single direct comparison was small and inconclusive. Available evidence does not establish an advantage of BCC or RFA.
