Sentinel lymph node biopsy in patients with male breast carcinoma.

abstract
BACKGROUND: Sentinel lymph node biopsy (SLNB) is now a widely implemented technique for evaluating the axilla in women with early stage breast carcinoma. Men who develop breast carcinoma are at similar risk as their female counterparts of developing the morbidities related to axillary dissection. SLNB is aimed at preventing these morbidities. In this study, the authors evaluated the role of SLNB in the treatment of men with early stage breast carcinoma. METHODS: Among the 1692 patients who underwent SLNB at the Memorial Sloan-Kettering Cancer Center, 16 men with breast carcinoma were identified. The charts and records of these 16 patients were reviewed retrospectively. RESULTS: The mean patient age was 57.2 years. The mean tumor size was 1.3 cm. In 15 of 16 patients (93.75%) and in all patients with T1 tumors, one or more sentinel lymph nodes were successfully identified. SLNB failed in one patient, who had a T2 tumor (3 cm). Ten of the 15 patients had negative sentinel lymph nodes (66.7%). Four of these patients had no additional lymph nodes removed, whereas six patients had additional lymph nodes removed, all of which were negative. Two patients (13.3%) had positive sentinel lymph nodes on frozen-section analysis and underwent immediate completion axillary dissection: Both had additional positive lymph nodes. Three patients (20.0%) had positive sentinel lymph nodes on further sectioning or immunohistochemistry, and two patients underwent completion axillary dissection: Neither patient had additional positive lymph nodes. The third patient had one immunohistochemically positive lymph node and did not undergo completion axillary dissection. CONCLUSIONS: SLNB for patients with breast carcinoma was as successful in men as it has been shown to be in women and may be offered as a management option to men with early stage breast carcinoma by surgeons who are experienced with the technique.
