Description

For patients undergoing breast conserving surgery (BCS) for breast cancer, cavity shave margin (CSM) resection has correlated to positive margin rate reductions, ranging from 50% to over 70%, and occult multifocal disease identification, ranging from 8% to 19%. There is a paucity of data on the impact of CSM on locoregional recurrence (LRR), therefore our study sought to compare whether rates of recurrence differed between partial mastectomy with CSM versus without.
