OBJECTIVES: A recent randomized controlled trial demonstrated an overall survival benefit to the addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to neoadjuvant chemotherapy (NACT) for stage III epithelial ovarian cancer (EOC). The objective of the current study was to quantify the cost-effectiveness of HIPEC in this setting. METHODS: A decision analytic cost-effectiveness model was designed from a payer perspective to compare 2 surgical management strategies for EOC: (1) interval cytoreductive surgery (ICS); (2) ICS + HIPEC. Overall survival and ostomy rates with HIPEC were modeled from published studies. We assumed that 25% of each arm would later undergo secondary cytoreductive surgery, with the ICS arm eligible for HIPEC at that time. Costs were obtained from Medicare data, published studies, and the financial department of an academic hospital. Quality of life was not different between the arms; we assigned utilities based on a prior time-trade off study of ovarian cancer treatment. A Monte Carlo probabilistic sensitivity analysis was performed in the base case; primary outcome was the incremental cost-effectiveness ratio (ICER), expressed in 2017 US Dollars/quality-adjusted life years (QALYs). RESULTS: ICS was the least costly strategy at $78,849, compared to ICS + HIPEC at $79,954. ICS + HIPEC was more effective than ICS (2.9 QALYs versus 2.45 QALYs for ICS). ICS + HIPEC was highly cost-effective, with an ICER of $2436/QALY compared to ICS. In one-way sensitivity analyses, probability of ostomy reversal and use of HIPEC at secondary cytoreduction did not substantially impact the cost-effectiveness of ICS + HIPEC. CONCLUSION: ICS + HIPEC constitutes cost-effective management of stage III EOC when NACT is performed.
