The study aimed to assess the frequency of Langer’s arch in patients undergoing axillary dissection for breast cancer.

From January-2015 to March-2020, in a general hospital in México City, female patients undergoing axillary dissection for breast cancer were studied. The analysis involved: demographic and anthropometric data, type of surgical treatment, histopathologic diagnosis, number of lymph nodes harvested, and frequency of Langer’s arch finding.

The sample studied was 123 axillary dissections. The mean age of the patients was 59 ± 10.5-years. Modified radical mastectomy was done in 117 cases (95.1%). Ductal carcinoma occurred in 96 cases (78%). The mean number of lymph nodes harvested was 24 ± 6.5. Langer’s arch finding occurred in 33 cases (26.8%).

Langer’s arch is frequent in our patients undergoing axillary dissection for breast cancer.
