The clinical manifestations and treatment of male breast cancer: a report of three cases

Male breast cancer is an extremely rare malignancy. We treated three male breast cancer patients. All three patients showed clinical N0 and received sentinel lymph node biopsy. Because the sentinel lymph node was positive for metastasis in one patient, a total mastectomy with axillary lymph node dissection was performed. The other two patients were negative for sentinel lymph node metastasis, and a simple mastectomy was performed. Two of the patients were postoperatively treated with tamoxifen; another patient was treated with adjuvant chemotherapy using taxotere and cyclophosphamide before tamoxifen. There was no recurrence in any of the three patients during an average follow-up period of 56.7 months (range 11.8–80.3). A sentinel lymph node biopsy is recommended for node staging in both male and female breast cancer patients as it is associated with a lower incidence of complications.
