Implication

Retrospective study evaluates loco-regional recurrence in breast cancer patients omitting axillary dissection, suggesting favorable outcomes.

Key Points

To evaluate the oncological outcomes in breast cancer patients with sentinel lymph node micrometastases undergoing mastectomy without axillary lymph node dissection.
Retrospective single-center study of 79 breast cancer patients from 2007 to 2020.
Patients underwent mastectomy without completion axillary lymph node dissection or post-mastectomy radiotherapy.
Analysis included clinicopathological characteristics and oncological outcomes.
Estimated 5-year loco-regional recurrence-free survival (LRFS) was 97.1%.
5-year distant disease-free survival (DDFS) was 94.6%.
5-year breast cancer-specific survival (BCSS) was 95.5%.
