Integration of Radiation and Reconstruction After Mastectomy.

Postmastectomy radiation therapy (PMRT) is a mainstay of local therapy for many breast cancer patients. Patients undergoing mastectomy typically are offered options for breast reconstruction. For patients who are candidates for PMRT, there are ongoing challenges with combining optimal radiation technique to prioritize oncologic outcomes, against the goals of minimizing toxicity and achieving the best reconstruction outcomes. The process by which these decisions are made continues to evolve as surgical and radiation techniques have improved and expanded, and as more patients with different risk profiles for local recurrence are receiving PMRT. We review the considerations regarding the different types of reconstruction and timing with radiation treatment. We also review the technical radiation consideration such as dose-fractionation, use of bolus and scar boost, exploring the controversies associated with the nuanced decisions regarding radiation and reconstructive surgery which are influenced by variables that are under continued investigation.
