Two patients (2/18) were prepubertal (<10 years), twelve (12/18) were pubertal (10-19 years), and four (4/18) were post-pubertal (≥20 years). The main clinical manifestations of 17 patients who were first diagnosed in our hospital were abnormal vaginal bleeding (8 cases, 8/17), abdominal pain and distension (6 cases, 6/17) and pelvic mass (3 cases, 3/17). Imaging examination showed that the median maximum diameter of the tumor was 10 cm (range: 5-37 cm), and ascites or pelvic effusion was present in 5 cases. Carbohydrate antigen 125 (CA<sub>125</sub>) level was >35.0 kU/L in 7 cases. All patients underwent fertility-preserving surgery and were classified as International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ [stage Ⅰa in 10 cases (10/18); stage Ⅰc in 8 cases (8/18)]. Six patients received platinum-based adjuvant chemotherapy after surgery, including 5 cases of BEP regimen (bleomycin+etoposide+cisplatin) and 1 case of PVB regimen (cisplatin+vincristine+bleomycin). Pathological examination showed that the tumors were unilateral in all cases, 8 cases (8/18) on the left side and 10 cases (10/18) on the right side. Macroscopically, the tumors were predominantly solid or cystic-solid. Microscopically, the tumors were mainly manifested as diffuse lamellar or multinodular solid tumors with variable number and size of follicular structures, and the follicular cavity was filled with basophilic or eosinophilic secretion. The cytoplasm was abundant with variable mitotic figures. Immunohistochemical staining showed that more than one sex cord mesenchymal marker was positive in all cases, epithelial membrane antigen (EMA) was negative, and cell proliferation-associated nuclear antigen (Ki-67) index was 5%-60%. Molecular analysis identified wild-type FOXL2 and DICER1 hotspot mutations in seven cases. One patient with recurrence harbored a TP53 nonsense mutation and a CDKN2A missense mutation, confirming anaplastic JGCT. The median follow-up time was 75.6 months (range: 4.1-201.4 months). One patient (1/18) developed pelvic and abdominal metastasis 23 months after the initial surgery. Among the 6 patients with premenarche, 4 patients had regular menstruation after surgery, and the other 2 patients were still young. The menstruation of patients with irregular menstruation before operation returned to normal after surgery.","PeriodicalId":10050,"journal":{"name":"中华妇产科杂志","volume":"61 8","pages":"658-668"},"PeriodicalIF":0.0,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148905138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The administration time, as well as the start and end times of cystoscopy, were recorded, along with the duration required for ureteral urine staining. <b>Results:</b> From March 2005 to March 2025, over the past 20 years, the Fourth Medical Center, Chinese PLA General Hospital has performed a total of 1 825 TVHUS. 10 to 15 minutes before the scheduled cystoscopy during the operation, water-soluble vitamin for injection was intravenously dripped.

Pregnant women were stratified into three groups according to their pre-pregnancy BMI: non-overweight/obesity, overweight and obesity. Multivariate logistic regression was used to analyze the effect of pre-pregnancy BMI on PE.
