[Male breast cancer: 19 case reports]

Breast cancer is rarely encountered in men. In developed countries, it accounts for less than 1% of cancers in men, whereas in women it represents about 23% of all cancers. A retrospective review was performed on 19 cases of men who underwent surgery for breast carcinoma between 1989 and 2000. The aim of this work was to analyse epidemiological and etiological aspects, circumstances of discovery, pathological characteristics, therapy modalities as well as prognostic factors. The mean age was 65.3 years. A high incidence of overweight, diabetes, hypertension and hypercholesterolemia was found. The most frequent clinical presentation was a firm subareolar lump, at a low stage (stage I 23% and stage II 41%). The most common pathological type was an infiltrating ductal carcinoma (89%). Hormone receptors where most often positive (92% for oestrogen and 100% for progesterone receptors). 84% of patients underwent simple mastectomy and axillary dissection, 74% chest wall irradiation after surgery, 26% received chemotherapy and 42% hormonal therapy. Median follow-up was 52 months. The estimated 2-year overall survival (OS) and disease-free survival (DFS) was respectively 93% and 87.5% and the 5-year OS and DFS respectively 86% and 75%. The management of male and female breast carcinoma is identical, as well as their prognosis at equal stages. However male breast carcinoma is more often diagnosed at a more advanced stage, thus a breast screening in men would permit a sooner diagnosis and a better prognosis.
