Objectives: The aim of this retrospective study is to assess the incidence of morbidity and mortality related to cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) and to evaluate their predictors, in patients with peritoneal metastasis of ovarian origin. Methods: A retrospective multicenter study was carried out investigating results from eight Italian institutions. A total of 276 patients met inclusion criteria. Predictors of morbidity and mortality were evaluated with univariate and multivariate analysis. Results: Overall morbidity was 71.4%, and severe complications occurred in 23.9% of the sample; 60-day mortality was 4.3%. According to univariate logistic regression models, grade 3-4 morbidity was related to Peritoneal Cancer Index (PCI) (OR 1.06; 95% CI 1.02-1.09; p<0.001), number of intraoperative blood transfusions (OR 1.21; 95% CI 1.10-1.34; p<0.001), Completeness of Cytoreduction (CC) score (OR 1.68; 95% CI 1.16-2.44; p=0.006) and number of anastomoses (OR 1.32; 95% CI 1.00-1.73; p=0.046). However, at themultivariate logistic regression analysis, only the number of intraoperative blood transfusions (OR 1.17; 95% CI 1.5-1.30; p=0.004) and PCI (OR 1.04; 95% CI 1.01-1.08; p=0.010) resulted as key predictors of severe morbidity. Furthermore, using multivariate logistic regression model, ECOG score (OR 2.45; 95% CI 1.21-4.93; p=0.012) and the number of severe complications (OR 2.16; 95% CI 1.03-4.52; p=0.042) were recorded as predictors of exitus within 60 days. Conclusions: The combination of CRS and HIPEC for treating peritoneal metastasis of ovarian origin has acceptable morbidity and mortality and, therefore, it can be considered as an option in selected patients.

Abstract

Methods: A retrospective multicenter study was carried out investigating results from eight Italian institutions. A total of 276 patients met inclusion criteria. Predictors of morbidity and mortality were evaluated with univariate and multivariate analysis. Results: Overall morbidity was 71.4%, and severe complications occurred in 23.9% of the sample; 60-day mortality was 4.3%. According to univariate logistic regression models, grade 3-4 morbidity was related to Peritoneal Cancer Index (PCI) (OR 1.06; 95% CI 1.02-1.09; p<0.001), number of intraoperative blood transfusions (OR 1.21; 95% CI 1.10-1.34; p<0.001), Completeness of Cytoreduction (CC) score (OR 1.68; 95% CI 1.16-2.44; p=0.006) and number of anastomoses (OR 1.32; 95% CI 1.00-1.73; p=0.046).
