ABSTRACT
Purpose:To explore the possibility of non-sent inel lymph node (NSN) metastases in early breast carcinoma patients with positi ve sentinel lymph node (SLN) and its clinical significance. Methods:The incidence and related clinical factors of NSN metas tases were analyzed in 84 early breast carcinoma patients with positive sentinel lymph node, who underwent radical mastectomy. Results:The metastatic NSN was identified in 41 of the 84 pati ents with positive sentinel lymph node (48.8%), the incidence of NSN metastases was related to primary tumor size, SLN metastatic focus size and HER-2 expressi on status, the incidence rate of NSN metastases is proportional to the size of t he primary tumor and metastatic SLN focus, patients with positive HER-2 expres sion have a high NSN metastases rate. Conclusions:The early breast carcinoma patients with
