This collaborative guideline considers several questions related to defining margins for patients who have reached breast-conserving surgery and WBI. It delineates when margins are positive and the necessary width to consider the margin negative. It also addresses the interaction between margin width and systemic therapy; biologic subtype; radiation therapy technique, fractionation and boost; invasive lobular carcinoma or lobular carcinoma in situ; and young age.
