Purpose: To investigate the clinico-pathological prognostic factors and treatment outcomes in patients with ovarian yolk sac tumors (YST).Methods: A multicenter, retrospective department database review was performed to identify patients with ovarian YST who underwent surgery between 2000 and 2017 at seven Gynecologic Oncology Centers in Turkey.Results: The study group consisted of 99 consecutive patients with a mean age of 23.9 years. While 52 patients had early stage (stage I-II) disease, the remaining 47 patients had advanced stage (stage III-IV) disease. The uterus was preserved in 74 (74.8%) of the cases. The absence of gross residual disease following surgery was achieved in 76.8% of the cases. Of the 54 patients with lymph node dissection (LND), lymph node metastasis was detected in 10 (18.5%) patients. Of the 99 patients, only 3 patients did not receive adjuvant therapy, and most of the patients (91.9%) received BEP (bleomycin, etoposide, cisplatin) chemotherapy. Disease recurred in 21 (21.2%) patients. The 5-year disease-free survival (DFS) and overall survival (OS) in the entire cohort were 79.2% and 81.3%, respectively. In multivariate analysis, only residual disease following initial surgery was found to be significantly associated with DFS and OS in patients with ovarian YST (p = 0.026 and p = 0.001, respectively).Conclusions: Our results demonstrate the significance of achieving no visible residual disease in patients with ovarian YST. Fertility-sparing approach for patients with no visible residual disease affected neither DFS nor OS. Although high lymphatic involvement rate was detected, the benefit of LND could not be demonstrated. [ABSTRACT FROM AUTHOR]- Published

Purpose: To investigate clinicopathological characteristics and oncological outcome of women with microinvasive BOTs.Methods: A retrospective multicenter case-control study was conducted on 902 patients with BOT, who underwent surgery from January 2002 to December 2015 at six participating gynecologic oncology centers from Turkey. Among 902 patients, 69 had microinvasive BOT. For every patient with microinvasive BOT, two controls were randomly selected from another database based on decade of age and stage of disease at diagnosis. The clinical-pathological characteristics and oncological outcomes were compared between BOT patients with and without stromal microinvasion. Risk factors for poor oncological outcomes were investigated in a multivariate analysis model. Overall survival (OS) and disease-free survival (DFS) were estimated using the Kaplan-Meier method.Results: Patients with microinvasive BOT had a significantly higher rate of recurrence than patients without microinvasive BOT (17.4 vs 7.8%, OR 3.55, %95 CI 1.091-11.59, p = 0.03). Stage at diagnosis (stage I versus II/III) and type of surgery (cystectomy versus others) were found as other significant prognostic factors for recurrence in multivariate analysis (OR 8.63, %95 CI 2.48-29.9, p = 0.001 and OR 19.4, %95 CI 3.59-105.6, p = 0.001, respectively). Stromal microinvasion was found as a prognostic factor for significantly shorter DFS (26.7 vs 11.9 months, p = 0.031, log rank). However, there was no significant difference in OS between two groups (p = 0.99, log rank).Conclusion: Stromal microinvasion is significantly associated with decreased DFS. In addition, our study confirms that the risk of recurrence is higher in patients with microinvasive BOT. [ABSTRACT FROM AUTHOR]- Published

The study aim to determine the clinicopathological factors for disease-free survival (DFS) and overall survival (OS) in women with vulvar cancer and to analyze the the possible effect of metformin on survival of the patients. From 2011 to 2017, medical records of 142 patients who underwent primary radical surgery for VC at 6 referral centers in Turkey were collected, retrospectively. The median age of the cohort was 67.0 years. 124 patients underwent radical surgery and inguinofemoral lymphadenectomy. The overall recurrence rate was 33.8% within a median follow-up time of 22 months. Five-year DFS and OS rates were 55.8% and 62.6%, respectively. Multivariate analysis showed surgical margin (HR:6.4, p= 0.017 for DFS; HR:13.6, p=0.009 for OS) and lymph node metastasis (HR: 4.1, p= 0.014 for DFS; HR: 6.3, p= 0.020 for OS) were the independent prognostic factors. There was no statistically difference in DFS and OS for patients who had used metformin. [ABSTRACT FROM AUTHOR]

Abstract: Objective(s). : To evaluate the relationship between preoperative platelet counts and prognostic factors extensively, among endometrial cancer patients, especially with respect to cervical involvement. Methods. : One-hundred fifty-five patients with endometrial carcinoma, who underwent surgery as the initial treatment consisting peritoneal cytology, total abdominal hysterectomy, bilateral salpingo-oophorectomy, systematic pelvic-paraaortic lymphadenectomy, and omentectomy were retrospectively analyzed. Results. : There were no differences with respect to age, histological type (endometrioid vs. non-endometrioid), depth of myometrial invasion, peritoneal cytology, LVSI, and lymphatic metastasis. However, advanced stage (stages III and IV), poorly differentiated tumor grade (grade 3), the presence of cervical and adnexal involvements were associated with significantly higher median preoperative platelet counts. Accepting 325.000/μl platelet count as a threshold value, multivariate analysis revealed cervical involvement (P = 0.008; OR = 1.84, 95% CI:1.17–2.89) and presence of high grade histology (P = 0.014; OR = 2.23, 95% CI:1.18–4.23, for grade 3 disease) to be significantly associated with higher platelet count. At a cut-off value of 326.000/μl, 42.3% sensitivity and 82.8% specificity for the prediction of cervical involvement was observed under receiver operator characteristic curve method. Conclusion(s). : Higher preoperative platelet counts, even in conditions with normal range (150.000–400.000/μl), may reflect poor prognostic factors such as cervical involvement and high grade among patients with endometrial carcinoma. Also, the higher platelet count should be taken into consideration for the necessity of radical hysterectomy. [Copyright &y& Elsevier]

WOS: 000338633500049, PubMed: 24870768, Background: To evaluate the incidence, diagnosis and management of GTN among 28 centers in Turkey. Materials and Methods: A retrospective study was designed to include GTN patients attending 28 centers in the 10-year period between January 2003 and May 2013. Demographical characteristics of the patients, histopathological diagnosis, the International Federation of Gynecology and Obstetrics (FIGO) anatomical and prognostic scores, use of single-agent and multi-agent chemotherapy, surgical interventions and prognosis were evaluated. Results: From 2003-2013, there were 1,173,235 deliveries and 456 GTN cases at the 28 centers. The incidence was calculated to be 0.38 per 1,000 deliveries. According to the evaluated data of 364 patients, the median age at diagnosis was 31 years (range, 15-59 years). A histopathological diagnosis was present for 45.1% of the patients, and invasive mole, choriocarcinoma and PSTTs were diagnosed in 22.3% (n=81), 18.1% (n=66) and 4.7% (n=17) of the patients, respectively. Regarding final prognosis, 352 (96.7%) of the patients had remission, and 7 (1.9%) had persistence, whereas the disease was mortal for 5 (1.4%) of the patients. Conclusions: Because of the differences between countries, it is important to provide national registration systems and special clinics for the accurate diagnosis and treatment of GTN.
