Cancer of the male breast: a review.

A review of 20 cases of male breast cancer in 17 patients from 1959 to 1990 was performed. The median age at presentation was 53.3 years (range: 29 to 79). At the time of diagnosis, 30% (6) patients were stage I, 65% (13) stage II, and 5% (1) stage IV. Surgery was the initial form of therapy in all cases either as a radical mastectomy, modified radical mastectomy, or total mastectomy. The median disease-free survival was 4.8 years with a 5-year disease-free survival of 41%, and with a 5-year overall survival of 47%. Seven patients are alive with no evidence of disease, two are alive with disease, five have died of disease, and two died of other causes. Estrogen receptor (ER) and progesterone receptor (PR) assays were performed on the tumors of 10 patients, with 80% being ER positive and 70% PR positive. The median disease-free survival for ER positive patients was 6 months with a 5-year disease-free survival of 12.5%. The overall median survival for this group was 2.9 years with an overall 5-year survival of 25%. In this review there was a high percentage of patients who were ER positive. The positive receptor status had value in predicting decreased survival.
