Axillary lymph node dissection versus sentinel lymph node biopsy alone for early breast cancer with sentinel node metastasis: A meta-analysis

摘要

Background: In early breast cancer patients with sentinel node metastasis, the effect of axillary lymph node dissection (ALND) is controversial. The purpose of this study is to compare the safety and efficacy of sentinel lymph node biopsy (SLNB) alone versus ALND in patients with early breast cancer and sentinel node metastasis.
