A predictive score for optimal cytoreduction at interval debulking surgery in epithelial ovarian cancer: a two- centers experience.

ABSTRACT: BACKGROUND:Optimal cytoreduction (macroscopic Residual Tumor, RT?=?0) is the best survival predictor factor in epithelial ovarian cancer (EOC). It doesn't exist a consolidated criteria to predict optimal surgical resection at interval debulking surgery (IDS). The aim of this study is to develop a predictive model of complete cytoreduction at IDS. METHODS:We, retrospectively, analyzed 93 out of 432 patients, with advanced EOC, underwent neoadjuvant chemotherapy (NACT) and IDS from January 2010 to December 2016 in two referral cancer centers. The correlation between clinical-pathological variables and residual disease at IDS has been investigated with univariate and multivariate analysis. A predictive score of cytoreduction (PSC) has been created by combining all significant variables. The performance of each single variable and PSC has been reported and the correlation of all significant variables with progression free survival (PFS) has been assessed. RESULTS:At IDS, 65 patients (69,8%) had complete cytoreduction with no residual disease (R?=?0). Three criteria independently predicted R?>?0: age???60 years (p?=?0.014), CA-125 before NACT >?550 UI/dl (p?=?0.044), and Peritoneal Cancer Index (PCI)?>?16 (p??16, a PSC???3 and the presence of R?>?0 after IDS were all significantly associated with shorter PFS (p??0). The PSC should be prospectively validated in a larger series of EOC patients undergoing NACT-IDS.
