Clinical feasibility and oncological safety of non-radioactive targeted axillary dissection after neoadjuvant chemotherapy in biopsy-proven node-positive breast cancer: a prospective diagnostic and prognostic study.

ABSTRACT:

Background

Targeted axillary dissection (TAD) includes biopsy of clipped lymph node and sentinel lymph nodes. However, clinical evidence regarding clinical feasibility and oncological safety of non-radioactive TAD in a real-world cohort remains limited.

Methods

In this prospective registry study, patients routinely underwent clip insertion into biopsy-confirmed lymph node. Eligible patients received neoadjuvant chemotherapy followed by axillary surgery. Main endpoints included the false-negative rate (FNR) of TAD and nodal recurrence rate.

Results

Data from 353 eligible patients were analyzed. After completion of neoadjuvant chemotherapy, 85 patients directly proceeded to axillary lymph node dissection (ALND), furthermore, TAD with or without ALND was performed in 152
