Cost-effectiveness analysis of a randomized study comparing radiosurgery with radiosurgery and whole brain radiation therapy in patients with 1 to 3 brain metastases.
2012
Methods: We carried out a decision analysis populated with data from patients with brain metastasis in a concurrent trial randomized to either stereotactic radiosurgery (SRS) and observation or SRS and whole brain radiation therapy. Outcomes included actual life years saved (LYS), quality-adjusted life years (QALYs), and incremental costeffectiveness ratio (ICER). Costs used were from the healthcare perspective and utilities were captured through a time-trade-off method, using 10-year, 5-year, and 1-year time horizons. One-way sensitivity analyses were carried out to determine robustness of the decision analysis model.
