Adoption of Hypofractionated and Ultrahypofractionated Adjuvant Radiation Therapy for Breast Cancer Across Main and Community Centers Within a Single Healthcare System

The present study shows that recent trial evidence supporting the use of shorter RT treatments changed practice among providers more rapidly at our main academic center versus our community sites. The reasons for this difference are not known; however, standardization of treatment by implementation of an adjuvant RT treatment algorithm may facilitate uniform care among patients with breast cancer and we are investigating the impact of this approach.
