Efficacy of intraperitoneal continuous hyperthermic chemotherapy as consolidation therapy in patients with advanced epithelial ovarian cancer: A long-term follow-up

Abstract

This trial was performed to determine the efficacy and progression-free and overall survivals of patients with advanced ovarian cancer who had been treated with intraperitoneal hyperthermic chemotherapy (IPHC). Ten patients with advanced ovarian cancer participated in this trial and were treated with IPHC. The median progression-free and overall survival rates for all patients treated in this study were 41.2 and 70.2 months, respectively. Two of ten patients received optimal primary cytoreduction surgery followed by IPHC; four of ten, optimal interval debulking surgery followed by IPHC; and four of ten, negative second-look operation followed by IPHC. The groups had 5 and 14.5, 17.75 and 38, and 82.75 and 130.25 months median progression-free and overall survival rates, respectively. Grades 3-4 toxicity included myelosuppresion, and nephropathy was detected. One patient required blood transfusions due to grade 4 anemia and thrombocytopenia. Another patient developed grade 3 nephrotoxicity but did not require continuous hemodialysis. IPHC was feasible, produced manageable toxicity, and showed promise for the treatment of advanced ovarian cancer. Negative second-look laparotomy followed by IPHC was especially effective when consolidation intraperitoneal chemotherapy had been indicated. It produced excellent median progression-free and overall survival rates.
