The results of personificated ovarian cancer patients with peritoneal carcinomatosis treatment

Abstract

The objective: to analyse of the experience of cytoreductive surgery using and hypenermic intraperitoneal chemperfusion (HIPEC) in patients with ovarian cancer IIIC stage, as well as overall and relapse-free survival in such patients. Materials and methods. 119 patients with ovarian cancer of the IIIC stage were involved into the study from 2013 to 2020 and they were treated at the University Clinic of Odessa National Medical University. Patients were divided into two groups: the clinical control group (n=53) included persons after suboptimal cytoreduction; the patients of the main group (n=66) had optimal or complete cytoreduction, and in some cases with subsequent intraoperative hyperthermic intraperitoneal chemotherapy. During the initial analysis of these groups, time (preoperative period, duration of surgery, number of postoperative bed-days), as well as the presence of complications in the postoperative period were determined. Results. In the main group there was an increase operation time due to large surgery volumes and the implementation of the HIPEC procedure with primary cytoreduction (p=0.001). In the postoperative period, an increase in the number of bed-days in the hospital in patients of the main group in relation to the control group was established, especially in those who had HIPEC (p=0.001). There was an increase in the number of surgical complications of class III-IV according to the Clavien-Dindo classification (from 5 % to 22.2 %) in patients after HIPEC. An increase in relapse-free survival from 10 months in the control group to 13-19 months in the main group was revealed. The recurrence median in the postoperative period in the control group was 10±1.3 months, and after interval cytoreduction and primary cytoreduction with HIPEC – 13±1.5 and 19±6.3 months, respectively. The index of relapse-free survival in the first 6 months in the control group was 63.2 %, in patients after optimal or complete cytoreduction – 88.0 %, in patients after optimal or complete cytoreduction and HIPEC – 90.4 %. One-year recurrence-free survival rate was 37.5 %, 63.2 % and 60.1 %, respectively, the average values of overall survival – 27.7±4.1 months versus 24.5±1.8 and 24.1±2.2 months, respectively. Conclusions. Cytoreductive surgery and methods of intraoperative hyperthermic intraperitoneal chemotherapy are perspective options of treatment of patients with peritoneal carcinomatosis by ovarian cancer regarding recurrence of the disease and survival, although they are accompanied by more postoperative complications and number of bed-days in hospital.
