Introduction

Cardiovascular disease (CVD) is the leading cause of death in women diagnosed with endometrial cancer. There is clinical evidence that exercise significantly reduces the risks of CVD and cancer recurrence; however, it is unclear whether there is value for money in integrating exercise into clinical cancer care for this population. This paper aimed to assess the long-term cost effectiveness of a 12-week supervised exercise intervention, compared with standard care, for women diagnosed with early-stage endometrial cancer.

Methods

A cost-utility analysis was conducted from the Australian health system perspective for a time horizon of five years using a five percent discount rate. A Markov cohort model was designed with six mutually exclusive health states: no CVD; post-stroke; post-coronary heart diseases; post-heart failure; post-cancer recurrence; and death. The model was populated from the best evidence available in the literature. The incremental cost-effectiveness ratio (ICER) and net monetary benefit were reported. Uncertainty in the results was explored using deterministic and probabilistic sensitivity analyses.

Results

Over the time horizon of five years, the incremental cost of supervised exercise versus standard care was AUD358 (USD236.74) and the incremental quality-adjusted life-year (QALY) was 0.079, resulting in an ICER of AUD5,148 (USD3,404) per QALY gained. The incremental net monetary benefit was AUD3,589 (USD2,373.24) and the likelihood that the supervised exercise intervention was cost effective at a willingness-to-pay threshold of AUD50,000 (USD33,062.75) per QALY was 99.5 percent.

Conclusions

This is the first economic evaluation of exercise for endometrial cancer survivors. The results suggest that exercise is cost effective in this population. Given the low uncertainty in the outcomes, efforts should focus on implementation of exercise as part of clinical cancer care.
