Repeat Surgery After Breast Conservation for the Treatment of Stage 0 to II Breast Carcinoma A Report From the National Cancer Data Base, 2004-2010

摘要

IMPORTANCE Although complete excision of breast cancer is accepted as the best means to reduce local recurrence and thereby improve survival, there is currently no standard margin width for breast conservation surgery. As a result, significant variability exists in the number of additional operations or repeat surgeries patients undergo to establish tumor-negative margins.
