Abstract

Aggressive surgical cytoreduction has been shown to have a positive impact on survival of patients with ovarian cancer. After first-line chemotherapy, 47% of patients relapse within 5 years, and median survival after second line chemotherapy is 10—15 months. Adding intraperitoneal chemohyperthermia (IPCH) to surgical cytoreduction could further control ceolomic spread of disease. The aim of this study was to determine morbidity and mortality, regional relapse-free survival and, preliminarily, overall survival after combining cytoreductive surgery with IPCH for the treatment of peritoneal carcinomatosis from ovarian epithelial cancer relapsed after prior chemotherapy. Thirty women affected with such a relapse were included. Patients underwent extensive cytoreductive surgery including tumor resections and peritonectomy, followed by intraoperative IPCH with cisplatin. Complete surgical cytoreduction down to nodules less than 2.5 mm (CC0—CC1) was obtained in 23 patients (77%). One patient died postoperatively from a pulmonary embolism. Major postoperative morbidity was 5/30 (16.7%). We registered one case of anastomotic leakage, a spontaneous ileum perforation, a postoperative cholecystitis, a hydrothorax, and one patient with bone marrow toxicity. Kaplan-Meier estimates of median locoregional relapse-free survival and median overall survival were 17.1 months and 28.1 months, respectively. Patients with CC0—CC1 had locoregional relapse-free and overall survival rates of 24.4 and 37.8 months, whereas the remainder had survival rates of 4.1 and 11.0 months. We concluded that cytoreductive surgery combined with IPCH is feasible with acceptable morbidity and mortality and seems to promise good results in selected patients affected with peritoneal carcinomatosis from ovarian cancer.
