    The Preoperative Albumin Level Is an Independent Prognostic Factor for Optimally Debulked Epithelial Ovarian Cancer
    (2017) Ayhan, Ali; Gunakan, Emre; Alyazici, Irem; Haberal, Nihan; Altundag, Ozden; Dursun, Polat; https://orcid.org/0000-0003-0197-6622; 28875365; AAJ-5802-2021; W-9219-2019
    Purpose A low albumin level has been reported to be a prognostic factor for various cancers. The aim of this study was to determine the association between preoperative serum albumin level and survival in patients with epithelial ovarian cancer (EOC). Methods Records of 337 patients with EOC that underwent optimal cytoreductive surgery were retrospectively reviewed. Threshold albumin level was planned as 32.5 g L-1 due to the statistical analyses. Results Mean overall survival was 51.5 months. Area under the ROC curve was found statistically significant for the discriminative role of albumin for survival outcome (AUC = 0.857, 95% CI 0.813-0.90, P < 0.001). The best cut-off point for albumin was determined as 32.5 g L-1. The sensitivity rate, specificity rate, positive and negative predictive values, and accuracy rate for this cut-off level were found 67.2, 91.2, 81.2, 83.1, and 82.5%, respectively. Preoperative hypoalbuminemia was noted in 101 (30.0%) of the patients, of which 6.2% had an albumin level < 25 g L-1. The albumin level was independently and significantly associated with overall survival (HR 2.6; 95% CI 2.1-3.1; P < 0.001). Subgroup analysis showed that patients with an albumin level < 32.5 and >= 32.5 g L-1 had mean estimated overall survival of 40.6 and 96.0 months, respectively. Age, stage, and presence of ascites were the other independent significant factors. Conclusions The preoperative albumin level is an independent prognostic factor for overall survival in optimally debulked EOC patients. Further investigations about preoperative albumin level in prognostic models will contribute to the literature.

    Oncologic outcomes in patients undergoing maximal or optimal cytoreductive surgery for Stage 3C serous ovarian, tubal or peritoneal carcinomas
    (2019) Gurkan, Damla; Akin, Aylin Ceren; Sahin, Hanifi; Tohma, Yusuf Aytac; Sahin, Eda Adeviye; Gunakan, Emre; Iflazoglu, Nidal; Haberal, Asuman Nihan; Ayhan, Ali; 0000-0001-9418-4733; 31482736
    The aim of this study was to evaluate overall survival (OS) and disease-free survival (DFS) of patients with Stage 3C serous ovarian, tubal and peritoneal carcinomas. A retrospective analysis of 111 patients who underwent maximal or optimal cytoreductive surgery was performed. Patients were divided into three groups as ovarian cancer (n = 47), tubal cancer (n = 24) and peritoneal cancer (n = 40). Median follow-up was 30 months. There was no significant difference in DFS and OS among the groups. Complete cytoreduction was an independent prognostic factor for DFS in all groups (HR 2.3, 95% CI 1.14-4.93; p=.020). Positive peritoneal cytology (HR 2.2, 95% CI 1.02-4.78; p=.044), and retroperitoneal lymph node involvement (HR 2.3, 95% CI1.11-4.89; p=.025) were independent risk factors for decreased OS, and extended cytoreduction (HR 2.7, 95% CI 1.05-6.99; p=.039) were independent risk factors for increased OS. In conclusion, these malignancies should be considered a single entity during treatment.IMPACT STATEMENT What is already known on this subject? Epithelial ovarian cancer is the second most common gynaecological cancer in women worldwide. There are different histological types including ovarian, tubal and peritoneal carcinomas in which malignant cells form in the tissue covering the ovary or lining the fallopian tube of peritoneum. Recent data have supported the view that these malignancies should be considered a single entity and should be treated the same way. What the results of this study add? In the present study, we evaluated overall survival and disease-free survival of patients with Stage 3C ovarian, tubal and peritoneal cancer undergoing maximal or optimal cytoreductive surgery. We found similar oncologic outcomes in all patient groups. To the best of our knowledge, this is the first study to compare oncologic outcomes of these similar and often confused malignancies in the literature. We, therefore, believe that the present study provides additional information to the body of knowledge on this topic. s are of these findings for clinical practice and/or further research? This study is important, as it indicates similar oncologic outcomes in patients undergoing maximal or optimal cytoreductive surgery for Stage 3C ovarian, tubal and peritoneal cancer. Based on these findings, clinicians should keep in mind that these malignancies should be considered a single clinical entity and be treated the same way. We believe that our study would pave the way for further studies regarding this subject.
