Breast conservation among older patients with early‐stage breast cancer: Locoregional recurrence following adjuvant radiation or hormonal therapy

Abstract

For patients with breast cancer undergoing breast‐conserving surgery (BCS), adjuvant radiation (RT) and hormonal therapy (HT) reduce the risk of locoregional recurrence (LRR). Although several studies have evaluated adjuvant HT ± RT, the outcomes of HT versus RT monotherapy remain less clear. In this study, the risk of LRR is characterized among older patients with early‐stage breast cancer following adjuvant RT alone, HT alone, neither, or both.
