SUPREMO Ten-Year Results: Chest‑Wall Irradiation After Mastectomy Lowers Local Recurrence but Does Not Improve 10‑Year Survival in Intermediate‑Risk Breast Cancer
The SUPREMO randomized trial found that postmastectomy chest‑wall irradiation reduces chest‑wall recurrence but does not improve 10‑year overall survival for intermediate‑risk breast cancer; a large real‑world analysis supports no overall survival benefit except possibly for pT3N0 disease.
