The purpose of the present study was to evaluate the clinical and pathological features and oncological outcomes of Brenner tumors (BT). Evaluation was performed on the data of 46 patients with BTs retrieved from the oncology clinic database and pathology reports between 2005 and 2020. The median (range) age of the patients was 52 (22-75) years. Median (range) tumor size was 52.5 (5.0-300) mm. The tumor was benign in 37 (80.4%), borderline in one (2.2%), and malignant in the remaining eight (17.4%). Ten (21.7%) of the tumors were detected incidentally. Mixed tumor, BT plus another ovarian pathology, was found in 13 (28.2%). Recurrence developed in 2/8 (25%) with malignant BT (MBT). The stage of these patients was 3C, and both received chemotherapy after surgery. BTs are rare and generally detected incidentally. MBTs are treated in the same way as epithelial tumors. Due to the rarity of these tumors, lymphadenectomy and optimal chemotherapy regimens are controversial issues.

Purpose: The aim of this study is to evaluate the oncologic outcome in patients with pure ovarian dysgerminomas treated and followed-up in our hospital. Methods: This study included 18 ovarian dysgerminoma patients with unilateral and/or bilateral salpingo-oophorectomy (BSO) ± hysterectomy+omentectomy+bilateral pelvic ± para-aortic lymphadenectomy+peritoneal cytologic sampling. Results: Four (22%) patients underwent definitive surgery, including type I hysterectomy and BSO. Only one of the remaining 14 patients underwent BSO because of bilateral streak gonad presence during intraoperative examination. Thirteen patients (72%) had conservative surgeries. In addition, staging surgeries were performed to all patients except for one patient with 16 weeks of pregnancy (patient #3) in the study group. Retroperitoneal lymphadenectomy was part of the staging procedure except for this pregnant patient. Lymph node metastasis was positive in four (22%) patients. Three (16%) patients recurred and none of them died because of disease during follow-up period. Two of the relapsed patients were treated with combination of surgery and chemotherapy, whereas the third patient received only chemotherapy for treatment. Conclusions: Fertility sparing surgery should be the choice of treatment in patients with pure ovarian dysgerminoma. In addition, staging surgery, including retroperitoneal lymph node dissection is obligatory for determining stage IA patients who are exempt from adjuvant chemotherapy. Close surveillance policy enables early detection of patients with recurrences in whom salvage therapy is highly curable.

We aimed to define the effect of tumor size on recurrence and survival rates in patients with stage I–II endometrioid-type endometrial cancer. A total of 550 patients who had total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic-paraaortic lymphadenectomy were included. Patients with extrauterine spread, sarcomatous components, or synchronized tumor and those who did not undergo lymphadenectomy or did not have data on tumor size were excluded. The median tumor size was 35 mm (range: 3–335 mm). According to the 2009 International Federation of Obstetrics and Gynecology (FIGO) criteria, 245 cases were defined as stage IA, 271 as stage IB, and 34 as stage II. The 5-year disease-free survival (DFS) rate was 92% and the 5-year disease-specific survival (DSS) rate was 99%. The effects of prognostic factors on DFS were evaluated. Older age, stage II disease, deep myometrial invasion, and receiving adjuvant radiotherapy were associated with decreased DFS. There was no statistically significant association between tumor size and DFS. The 5-year DFS for patients with a tumor diameter of 35 mm (P = 0.128). Tumor size was not a risk factor predicting recurrence in patients with stage I or II endometrioid-type endometrial cancer who had lymphadenectomy.

To evaluate uncommon types of borderline ovarian tumors (BOT) and define the clinical, surgical, and pathologic features. Seventeen patients who were treated in our hospital between 1990 and 2017 were identified. Patients’ data were collected from the gynecologic oncology clinic electronic database, patients’ files, and pathology reports. Conservative surgery was defined as preservation of the uterus and at least part of one ovary. The mean age was 47 (range, 22-70) years. Based on histopathologic tumor type, there was mixed tumor in five (29.4%) patients, endometrioid-type in nine (52.9%), seromusinous-type in two (11.8%), and Brenner-type in one (5.9%). Conservative surgery was performed in 4 patients. Two patients with endometrioid BOT had synchronous endometrial pathology, including one (11%) patient with endometrial cancer, one (11%) with endometrial hyperplasia without atypia, and 3 (33%) patients had endometriosis. The median follow-up was 19 (range, 1-137) months. No recurrence was observed during the follow-up period. In our small volume case series, it could be said that non-serous/non-mucinous BOT has excellent prognosis. However, endometrial pathology should be checked in endometrioid type.
