Reasons for re-excision after lumpectomy for breast cancer: insight from the American Society of Breast Surgeons Mastery(SM) database.

摘要

Half of re-excisions after initial lumpectomy were performed for margins that are positive. Most of the remainder were for negative close (<1-2 mm) margins. This information corroborates surgeon survey data regarding reasons for re-excision and provides proof of concept the Mastery(SM) Program can capture surgical outcome data in real time, providing opportunity and a method for future performance improvement.
