Choosing Wisely? Patterns and Correlates of the Use of Hypofractionated Whole Breast Radiation Therapy in the State of Michigan

Abstract

Hypofractionated whole breast radiation therapy (HRT) reduces the cost and burden of adjuvant RT for breast cancer and has equivalent outcomes to standard fractionation for appropriate patients. Recent studies have suggested that utilization of HRT is low and variable. We investigated patterns and correlates of HRT in a consortium of RT practices in Michigan to determine variation at the practice level and whether use reflects individualization based on potentially relevant patient characteristics (such as habitus, age, chemotherapy receipt, or laterality).
