Male breast cancer: a clinicopathological study of an Egyptian population (Alexandria experience).

ABSTRACT

AIM OF THE STUDY The purpose of this retrospective study is to evaluate the clinicopathological features and treatment results of male breast cancer presented to our tertiary referral center. MATERIAL AND METHODS: Between January 1998 and December 2005, a total of 39 men with breast cancer treated at Alexandria Main University Hospital and their medical records were reviewed. RESULTS: The median age of patients was 59 years. Only 3 (7.7%) patients had positive family history. All patients presented by breast swellings that were associated with axillary mass in about one third of them. Around 80% had hormone receptor positive (estrogen and/or progesterone receptors). Two third of patients had advanced T-stage (T3 and T4). Left sided breast cancer occurred in 51.3%. Infiltrating ductal carcinoma was the most common type of histology encountered and grade 2 was the predominant grade of tumor. Modified radical mastectomy was the most common (87.2%) type of surgery done followed by chemotherapy for 32 patients and loco-regional radiotherapy for 20 patients. Tamoxifen was administered in 31 patients. Distant relapse occurred in 7 patients (17.9%) and local recurrence occurred in 2 patients (5.1%). The 5-year disease-free survival (DFS) was 82% and the 5-year overall survival (OS) rate was 84%. Only negative axillary lymph node and positive hormone receptor status were significantly associated with favorable DFS and OS. T-stage, grade of tumor and type of chemotherapy given had no statistically significant impact on either DFS or OS. CONCLUSIONS: Male breast cancer is still under-investigated and further researches are warranted.
