Male breast cancer: an 11 year review of 66 patients.

A review was conducted of 66 men with carcinoma of the breast seen at this institution between 1981 and 1992. The results of the study suggest that there are many similarities between breast cancer in men and women. The most common clinical presentation was a lump in the breast. The majority of tumors were T1 or T2, and infiltrating ductal carcinoma was the predominant histological type. Axillary nodal status and histological grade were predictive of survival. The pattern of recurrence and survival rates were similar to those seen in women. Some differences, however, were evident. Tumors were centrally located in the majority of patients and there was a high frequency of nipple involvement. The hormone receptor positivity rate was high and the median age at presentation was older. In comparison to a previous report of the same disease from this institution 10 years ago, fewer patients underwent radical surgical procedures and more patients received adjuvant systemic therapy. These approaches are justified since there are many biological similarities between breast cancer in men and women.
