Cost Effectiveness of Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Management of Colorectal Peritoneal Carcinomatosis.

Abstract

BACKGROUND:

Peritoneal carcinomatosis from colorectal cancer is a stage 4 disease for which palliative chemotherapy has traditionally been considered the mainstay of treatment. Since the development of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) by Sugarbaker, this combined method treatment has resulted in improved survival outcomes with acceptable morbidity for selected patients with peritoneal carcinomatosis. This study examined the cost effectiveness of CRS and HIPEC compared with palliative chemotherapy for patients with peritoneal carcinomatosis from colorectal cancer within the context of the Singaporean health care system.

METHODS:

A retrospective review of patients with peritoneal carcinomatosis from histologically proven colorectal cancer treated at the National Cancer Centre Singapore (NCCS) was conducted.

RESULTS:

The average cost of CRS and HIPEC per patient was S$83,680.26, and the median overall survival period was 47 months. The calculated cost per life year attained for a patient who underwent CRS and HIPEC was S$21,365.19 per life year. In comparison, the average cost of palliative chemotherapy was S$44,478.87, with a median overall survival of 9 months, and the calculated cost per life year attained for a patient in this treatment group was S$59,305.16 per life year.

CONCLUSION:

The findings show that CRS and HIPEC results in prolonged survival for selected patients with colorectal peritoneal carcinomatosis and a lower cost per life year attained than for the traditionally used palliative chemotherapy. It should logically be the preferred treatment of choice for selected patients with colorectal peritoneal metastasis.
