Item Can complete blood count inflammatory parameters in epithelial ovarian cancer contribute to prognosis? - a survival analysis(2019) Ceran, Mehmet Ufuk; Tasdemir, Umit; Colak, Eser; Gungor, Tayfun; 0000-0003-1923-2373; 0000-0002-8184-7531; 30744662SubjectiveThe aim of the present study was to investigate the prognostic significance of preoperative complete blood count inflammatory markers in women operated for invasive Epithelial Ovarian Cancer (EOC).MethodTwo hundred forty four patients that underwent operation with the diagnosis of invasive EOC between 2006 and 2014 were included in the study. The date of operation, date of recurrence and final mortality evaluations were performed for survival analysis. The sensitivity, specificity, PPV and NPV were separately calculated with ROC analysis. Survival analysis was carried out with Kaplan Meier-Log Rank Method.ResultsFive-years overall survival rate was 56, 9% and 5-year disease-free survival (DFS) rate was 45,5%. Advanced disease stage, moderate-poor tumor differentiation, and the presence of recurrence were determined to have significant inverse relation at mean survival and 5-year survival rates. Neutrophil/lymphocyte ratio (NLR) and Platelet lymphocyte ratio (PLR) had prognostic effect on both DFS and overall survival based upon the cut-off values determined in the study (PLR=231, s36, NLR=3,83). Histopathological subtypes were not found to have any prognostic value. In correlation analysis, PLR and NLR had positive correlation with each other and negative correlation with overall survival.ConclusionsInflammatory markers such as NLR and PLR have independent prognostic value for women who undergo surgery for invasive EOC.Item Does the primary route of spread have a prognostic significance in stage III non-serous epithelial ovarian cancer?(2018) Coban, Gonca; Sahin, Hanifi; Meydanli, Mehmet Mutlu; Sari, Mustafa Erkan; Yalcin, Ibrahim; Ozkan, Nazli Topfedaisi; Cuylan, Zeliha Firat; Erdem, Baki; Gungorduk, Kemal; Akbayir, Ozgur; Dede, Murat; Salman, Mustafa Coskun; Gungor, Tayfun; Ayhan, Ali; 0000-0002-3285-5519; 29506569; AAI-9974-2021Background: The purpose of this retrospective study was to determine the prognosis of non-serous epithelial ovarian cancer (EOC) patients with exclusively retroperitoneal lymph node (LN) metastases, and to compare the prognosis of these women to that of patients who had abdominal peritoneal involvement. Methods: A multicenter, retrospective department database review was performed to identify patients with stage III non-serous EOC at 7 gynecologic oncology centers in Turkey. Demographic, clinicopathological and survival data were collected. The patients were divided into three groups based on the initial sites of disease: 1) the retroperitoneal (RP) group included patients who had positive pelvic and / or para-aortic LNs only. 2) The intraperitoneal (IP) group included patients with > 2 cm IP dissemination outside of the pelvis. These patients all had a negative LN status, 3) The IP / RP group included patients with > 2 cm IP dissemination outside of the pelvis as well as positive LN status. Survival data were compared with regard to the groups. Results: We identified 179 women with stage III non-serous EOC who were treated at 7 participating centers during the study period. The median age of the patients was 53 years, and the median duration of follow-up was 39 months. There were 35 (19.6%) patients in the RP group, 72 (40.2%) in the IP group and 72 (40.2%) in the IP/RP group. The 5-year disease-free survival (DFS) rates for the RP, the IP, and IP/ RP groups were 66.4%, 37.6%, and 25.5%, respectively (p = 0.002). The 5-year overall survival (OS) rate for the RP group was significantly longer when compared to those of the IP, and the IP/RP groups (74.4% vs. 54%, and 36%, respectively; p = 0.011). However, we were not able to define "RP only disease" as an independent prognostic factor for increased DFS or OS. Conclusions: Primary non-serous EOC patients with node-positive-only disease seem to have better survival when compared to those with extra-pelvic peritoneal involvement.Item Comparison of stage III mucinous and serous ovarian cancer: a case-control study(2018) Ayhan, Ali; Cuylan, Zeliha Fırat; Karabuk, Emine; Oz, Murat; Turan, Ahmet Taner; Meydanli, Mehmet M.; Taskin, Salih; Sari, Mustafa Erkan; Sahin, Hanifi; Ulukent, Suat C.; Akbayir, Ozgur; Gungorduk, Kemal; Gungor, Tayfun; Kose, Mehmet F.; 30376858Background: The purpose of this case-control study was to compare the prognoses of women with stage III mucinous ovarian carcinoma (MOC) who received maximal or optimal cytoreduction followed by paclitaxel plus carboplatin chemotherapy to those of women with stage III serous epithelial ovarian cancer (EOC) treated in the similar manner. Methods: We performed a multicenter, retrospective review to identify patients with stage III MOC at seven gynecologic oncology departments in Turkey. Eighty-one women with MOC were included. Each case was matched to two women with stage III serous EOC in terms of age, tumor grade, substage of disease, and extent of residual disease. Survival estimates were measured using Kaplan-Meier plots. Variables predictive of outcome were analyzed using Cox regression models. Results: With a median follow-up of 54months, the median progression-free survival (PFS) for women with stage III MOC was 18.0months (95% CI; 13.8-22.1, SE: 2.13) compared to 29.0 months (95% CI; 24.04-33.95, SE: 2.52) in the serous group (p = 0.19). The 5-year overall survival rate of the MOC group was significantly lower than that of the serous EOC group (44.9% vs. 66.3%, respectively; p < 0.001). For the entire cohort, presence of multiple peritoneal implants (Hazard ratio [HR] 2.39; 95% confidence interval [CI], 1.38-4.14, p = 0.002) and mucinous histology (HR 2.28; 95% CI, 1.53-3.40, p < 0.001) were identified as independent predictors of decreased OS. Conclusion: Patients with MOC seem to be 2.3 times more likely to die of their tumors when compared to women with serous EOC.
