Phase II study of regional treatment for peritoneal carcinomatosis

Abstract

Background Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy and early postoperative intraperitoneal chemotherapy is becoming an accepted treatment of carcinomatosis. Methods Between February 2000 and January 2008, there were 101 consecutive patients with carcinomatosis who were treated with cytoreductive surgery + hyperthermic intraperitoneal chemotherapy and early postoperative intraperitoneal chemotherapy. Patient and tumor characteristics, surgical details, complications, disease-free survival (DFS), and overall survival (OS) were recorded prospectively. Results The majority (82%) of patients, median age 49 years (range, 18–77 y), had complete macroscopic cytoreduction (completeness of cytoreduction score, 0) despite a generally extensive tumor burden. Perioperative mortality and grade III/IV morbidity rates were 4% and 39%, respectively. Preliminary median DFS and OS have not been defined for appendix tumors at a median follow-up period of 16 months (range, 1–86 mo). Median DFS and OS for colonic tumors are 8 months and 26 months, respectively, with a median follow-up period of 12 months (range, 1–48 mo). Conclusions Combined regional treatment is feasible and holds significant promise for the treatment of peritoneal carcinomatosis.
