Abstract

Objectives: Our purpose was to assess the cost-effectiveness of intraperitoneal chemohyperthermia (IPCH) compared to palliative chemotherapy (STANDARD) against peritoneal carcinomatosis arising from colorectal cancer.

Methods: We performed a retrospective study of 96 patients whose peritoneal carcinomatosis had been diagnosed between January 1998 and December 2003 and treated either with IPCH or with palliative chemotherapy in French comprehensive cancer centers. Patients were followed up over a 3-year period. Effectiveness was measured by restricted mean survival at 3 years. The Bang and Tsiatis method was used to handle cost-censored data. The confidence limits of the mean cost per patient in each group and the mean incremental cost per life-year saved were computed using 1000 bootstrapreplicates. We also computed an acceptability curve for the incremental cost-effectiveness ratio (ICER).

Results: We found that IPCH improved survival and was more costly than STANDARD treatment. Over a 3-year observation period, IPCH yielded an average survival gain of 8.3 months at the additional cost of euro58,086 (95% confidence interval 35,893-112,839) per life-year saved.

Conclusion: The ICER of IPCH is acceptable given the severity and burden of peritoneal carcinomatosis for which there is no alternative curative treatment.
