Objective: This study aimed to compare the thiol/disulfide balance, myeloperoxidase, and ischemia-modified albumin levels in the follicular fluid (FF) of poor ovarian response (POR) and normal ovarian response (NOR) women who received intracytoplasmic sperm injection (ICSI). Methods: The study was performed between March 2021 and April 2022 at the Department of Obstetrics and Gynecology, Center for Reproductive Medicine, Ankara City Hospital. The study included 27 POR and 35 NOR women who underwent ICSI. FF was obtained after the controlled ovarian stimulation cycle. The FF thiol/disulfide balance was detected using spectrophotometric methods. A correlation analysis was conducted to determine whether these oxidative stress markers could contribute to predicting oocyte quality. Results: Disulfide levels were significantly higher in the NOR group than in the POR group (p=0.014). The number of fertilized egg (2PN) oocytes was positively correlated with the total thiol level (r=0.258, p=0.046). The disulfide level was positively correlated with the anti-Müllerian hormone level (r=0.262, p=0.039) and the total number of retrieved oocytes (r=0.335, p=0.008). Conclusion The disulfide levels differed significantly between the NOR and POR groups. The statistically significant differences of fewer metaphase II oocytes and lower percentage of good-quality embryos in the NOR group compared to the POR group might have resulted from the NOR group’s elevated disulfide levels. The total thiol levels correlated with the total of 2PN oocytes. Future studies should examine the thiol/disulfide balance at assisted reproductive technology centers to predict which oocytes could be fertilized.

Objective: To define the clinical, histopathological features and the prognostic factors affecting survival in patients with adult granulosa cell tumors of the ovary (AGCT). Methods: A 322 patients whose final pathologic outcome was AGCT treated at nine tertiary oncology centers between 1988 and 2021 participated in the study. Results: The mean age of the patients was 51.3±11.8 years and ranged from 21 to 82 years.According to the International Federation of Gynecology and Obstetrics 2014, 250 (77.6%) patients were stage I, 24 (7.5%) patients were stage II, 20 (6.2%) patients were stage III, and 3 (7.8%) were stage IV. Lymphadenectomy was added to the surgical procedure in 210(65.2%) patients. Lymph node involvement was noted in seven (3.3%) patients. Peritoneal cytology was positive in 19 (5.9%) patients, and 13 (4%) had metastases in the omentum. Of 285 patients who underwent hysterectomy, 19 (6.7%) had complex hyperplasia with atypia/ endometrial intraepithelial neoplasia, and 8 (2.8%) had grade 1 endometrioid endometrial carcinoma. It was found that 93 (28.9%) patients in the study group received adjuvant treatment. Bleomycin, etoposide, cisplatin was the most commonly used chemotherapy protocol. The median follow-up time of the study group was 41 months (range, 1–276months). It was noted that 34 (10.6%) patients relapsed during this period, and 9 (2.8%)patients died because of the disease. The entire cohort had a 5-year disease-free survival (DFS) of 86% and a 5-year disease-specific survival of 98%. Recurrences were observed only in the pelvis in 13 patients and the extra-abdominal region in 7 patients. The recurrence rate increased 6.168-fold in patients with positive peritoneal cytology (95% confidence interval [CI]=1.914–19.878; p=0.002), 3.755-fold in stage II–IV (95% CI=1.275–11.063; p=0.016), and 2.517-fold in postmenopausal women (95% CI=1.017–6.233; p=0.046) increased. Conclusion In this study, lymph node involvement was detected in 3.3% of patients with AGCT. Therefore, it was concluded that lymphadenectomy can be avoided in primary surgical treatment. Positive peritoneal cytology, stage, and menopausal status were independent prognostic predictors of DFS.
