Breast conserving surgery (BCS), also known as quadrantectomy, sectorectomy, or lumpectomy, consists of surgical removal of the primary tumor, with negative margins and whole breast radiotherapy (RT). The addition of RT to conservative surgery reduces the local recurrence rate by 50%, with an impact on mortality at 15 years, according to a meta-analysis by the Early Breast Cancer Trialists Collaborative Group (EBCTCG), showing that the omission of radiotherapy in BCS is not recommended.

It showed increased LR rates significantly associated with young age (<50 years), estrogen receptor negative, grade III, more than 4 positive lymph nodes and re-intervention. CrossRefGoogle Scholar
