Audit of local recurrence following breast conservation surgery with 5-mm target margin and hypofractionated 40-Gray breast radiotherapy for invasive breast cancer

Abstract

Our treatment regimen, combining BCS with a 5-mm target margin and hypofractionated 40-Gy RT, results in an extremely low rate of IBTR, and compares favourably with the target IBTR rate of <5% defined by the Association of Breast Surgeons (ABS) at BASO guidelines.
