Axillary Dissection <i>vs</i>. no Axillary Dissection in Breast Cancer Patients With Positive Sentinel Lymph Node: A Single Institution Experience

BACKGROUND/AIM: Axillary surgery of breast cancer patients is undergoing a paradigm shift, as axillary lymph node dissection's (ALND) usefulness is being questioned in the treatment of patients with tumor-positive sentinel lymph node biopsy (SLNB). The aim of this study was to investigate the overall survival (OS) and relapse-free survival (RFS) of patients with positive SLNB treated with ALND or not. PATIENTS AND METHODS: We investigated 617 consecutive patients with cN0 operable breast cancer with positive SLNB undergoing mastectomy or conservative surgery. A total of 406 patients underwent ALND and 211 were managed expectantly. RESULTS: No significant difference in OS and RFS was found between the two groups. The incidence of loco-regional recurrence in the SLNB-only group and the ALND group was low and not significant. CONCLUSION: The type of breast cancer surgery and the omission of ALND does not improve OS or RSF rate in cases with metastatic SLN.
