Background: Hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) has been recently proposed to treat peritoneal carcinomatosis arising from colon adenocarcinoma, which is usually regarded as a lethal clinical entity. The purpose of this study was to evaluate the clinical outcome of this combined treatment. Methods: A retrospective study of 46 patients treated for peritoneal carcinomatosis from colon adenocarcinoma was performed. Thirty-four patients were treated with complete cytoreductive surgery immediately followed by intraoperative HIIC with mitomycin C and cisplatin. The clinical outcome of these 34 patients was analyzed; the median follow-up period was 14.5 months. Results: No postoperative deaths were reported. The postoperative morbidity rate was 35%. No severe locoregional or systemic toxicity was observed. The 2-year overall survival was 31%, and the median survival time and the median time to local disease progression were 18 and 13 months, respectively. Survival and local disease control in patients with well- and moderately differentiated colon adenocarcinoma were significantly better than in those with poorly differentiated tumors. Conclusions: Considering the dismal prognosis of this condition, HIIC seems to achieve encouraging results in a selected group of patients affected with resectable peritoneal carcinomatosis arising from colon adenocarcinoma. These findings support the conduction of formal phase III randomized trials.

Abstract

Background: Hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) has been recently proposed to treat peritoneal carcinomatosis arising from colon adenocarcinoma, which is usually regarded as a lethal clinical entity. The purpose of this study was to evaluate the clinical outcome of this combined treatment. Methods: A retrospective study of 46 patients treated for peritoneal carcinomatosis from colon adenocarcinoma was performed. Thirty-four patients were treated with complete cytoreductive surgery immediately followed by intraoperative HIIC with mitomycin C and cisplatin. The clinical outcome of these 34 patients was analyzed; the median follow-up period was 14.5 months. Results: No postoperative deaths were reported. The postoperative morbidity rate was 35%. No severe locoregional or systemic toxicity was observed. The 2-year overall survival was 31%, and the median survival time and the median time to local disease progression were 18 and 13 months, respectively. Survival and local disease control in patients with well- and moderately differentiated colon adenocarcinoma were significantly better than in those with poorly differentiated tumors. Conclusions: Considering the dismal prognosis of this condition, HIIC seems to achieve encouraging results in a selected group of patients affected with resectable peritoneal carcinomatosis arising from colon adenocarcinoma. These findings support the conduction of formal phase III randomized trials.
