Is the use of radiation therapy after mastectomy cost-effective?
With the publication of two randomized trials showing an improvement in overall survival after the use of postmastectomy radiation therapy, interest in the use of radiation therapy in this setting has been rekindled. These results are in contrast to those reported in the most recent meta-analysis of the Early Breast Cancer Trialists' Collaborative Group, in which a statistically significant survival benefit was not detected. Although evidence of a survival benefit was sufficient in the past for an intervention to gain acceptance, payers are increasingly interested in knowing whether its use is also cost-effective. This article briefly reviews the methods used in performing cost-effectiveness analyses, summarizes the results of one published and a second preliminary cost-effectiveness analysis of postmastectomy radiation therapy, and highlights several areas for future research.
