(2020) Sahin Uysal, Nihal; Boyraz, Gokhan; Usubutun, Alp; Tuncer, Zafer S.; 0000-0001-5385-5502; 32779347; AAA-9475-2020
Aim The aim of the study was to evaluate the results of the laparotomies due to gynecological pathologies in breast cancer patients and to assess the distribution of gynecological pathologies and the clinical and laboratory findings contributing to the diagnosis. Methods This study was conducted between years 2002 and 2011 at Hacettepe University Hospital. We obtained information about 86 consecutive breast cancer patients, including age, time of diagnosis and pathology of breast cancer, hormone receptor status, history of endocrine therapy, presenting symptoms, ultrasonography findings, CA 125 levels, endometrial biopsy results, type of gynecological surgery and pathology results. Data were analyzed with the use of SPSS software. Results Twenty-one (24.4%) out of 86 patients had endometrial pathology, and 24 (27.9%) had adnexal pathology. Fourteen patients (16.2%) had malignant pathology, and of them, 11 had ovarian cancer 3 had endometrial cancer. There were five abnormal cytological findings: 2 ASCUS, 1 LSIL, 1 ASC-H and 1 adenocarcinoma. The patient with the cytology report of adenocarcinoma had the final diagnosis of endometrial cancer. Of the patients, 67 (77.9%) used tamoxifen, whereas 19 (22.1%) did not. Thirty-three patients (38.4%) with gynecological pathologies were detected incidentally during routine follow-up of breast cancer. Conclusion This study supports the increase of the gynecological pathology incidence in breast cancer patients and the recommendation of close gynecological follow-up in these patients. Asymptomatic patients might also develop genital cancer. The ultrasonographic appearance of the adnexal masses or endometrial thickness and any abnormal vaginal bleeding or high CA 125 levels are important parameters for evaluating breast cancer patients.

Objective: To determine factors influencing overall survival following recurrence (OSFR) in women with low-risk endometrial cancer (EC) treated with surgery alone. Methods: A multicenter, retrospective department database review was performed to identify patients with recurrent "low-risk EC" (patients having less than 50% myometrial invasion [MMI] with grade 1 or 2 endometrioid EC) at 10 gynecologic oncology centers in Turkey. Demographic, clinicopathological, and survival data were collected. Results: We identified 67 patients who developed recurrence of their EC after initially being diagnosed and treated for low-risk EC. For the entire study cohort, the median time to recurrence (TTR) was 23 months (95% confidence interval [CI]=11.5-34.5; standard error [SE]=5.8) and the median OSFR was 59 months (95% CI=12.7-105.2; SE=23.5). We observed 32 (47.8%) isolated vaginal recurrences, 6 (9%) nodal failures, 19 (28.4%) peritoneal failures, and 10 (14.9%) hematogenous disseminations. Overall, 45 relapses (67.2%) were loco-regional whereas 22 (32.8%) were extrapelvic. According to the Gynecologic Oncology Group (GOG) Trial-99, 7 (10.4%) out of 67 women with recurrent low-risk EC were qualified as high-intermediate risk (HIR). The 5-year OSFR rate was significantly higher for patients with TTR >= 36 months compared to those with TTR <36 months (74.3% compared to 33%, p=0.001). On multivariate analysis for OSFR, TTR <36 months (hazard ratio [HR]=8.46; 95% CI=1.65-43.36; p=0.010) and presence of HIR criteria (HR=4.62; 95% CI=1.69-12.58; p=0.003) were significant predictors. Conclusion: Low-risk EC patients recurring earlier than 36 months and those carrying HIR criteria seem more likely to succumb to their tumors after recurrence.
Is the Oncological Outcome of Early Stage Uterine Carcinosarcoma Different from That of Grade 3 Endometrioid Adenocarcinoma?
(2021) Gungorduk, Kemal; Plett, Helmut; Gulseren, Varol; Meydanli, Mutlu; Boyraz, Gokhan; Ozdemir, Isa Aykut; Sahin, Hanifi; Senol, Taylan; Yildirim, Nuri; Turan, Taner; Oge, Tufan; Gokcu, Mehmet; Taskin, Salih; Ayhan, Ali; Ataseven, Beyhan; 33249415; AAJ-5802-2021
Aim: The clinicopathologic characteristics, recurrence patterns, and survival of patients with grade 3 endometrial cancer (G3-EAC) and uterine carcinosarcoma (UCS) were compared. Materials and Methods: The medical records of patients treated for G3-EAC and UCS between January 1996 and December 2016 at 11 gynecologic oncology centers in Turkey and Germany were analyzed. Results: Of all patients included in the study, 161 (45.1%) were diagnosed with UCS and 196 (54.9%) with G3-EAC at FIGO stage I-II (early stage) disease. The recurrence rate was higher in patients with UCS than in those with G3-EAC (17.4 vs. 9.2%, p = 0.02). The 5-year disease-free survival (DFS; 75.2 and 80.8%, respectively; p = 0.03) and overall survival (OS; 79.4 and 83.4%, respectively; p = 0.04) rates were significantly lower in the UCS group compared to the G3-EAC group. UCS histology was an independent prognostic factor for decreased 5-year DFS (HR 1.8, 95% CI 1.2-3.2; p = 0.034) and OS (HR 2.7, 95% CI 1.3-6.9; p = 0.041) rates. Conclusions: The recurrence rate was higher in UCS patients than in G3-EAC patients, regardless of disease stage. DFS and OS were of shorter duration in UCS than in G3-EAC patients. Adequate systematic lymphadenectomy and omentectomy were an independent prognostic factor for increased 5-year DFS and OS rates.
