[Cancer of the breast in men. 106 cases].
In a retrospective and multicentre study 106 cases treated from 1970 to 1985 were analysed. The patients' median age was 64 years. TNM classification showed 20 T1, 48 T2, 2 T3, 32 T4 and 4 Tx. Twenty one patients had clinical gynaecomastia; 99 underwent surgery and 85 radiotherapy; 32 received adjuvant chemotherapy or hormonal therapy. The main histological type was ductal infiltrating carcinoma; 82 axillary dissections were performed, and positive lymph nodes were found in 67 percent of the cases. Hormone receptors were positive in 15 out of 20 measured cases. Five and 10 years overall survival rates (Kaplan-Meier) were 57 and 37 percent, and corrected survival rates 68 and 55 percent respectively. The main prognostic factor remains the clinical size of the tumour (T) and histologically axillary node status (pN). Eleven patients developed a second metachronous cancer. The aetiology of male breast cancer is a poorly known as that of female breast cancer. Nevertheless, imbalance among oestrogens and androgens due to metabolic, infectious or pharmacological causes is probably responsible, at least in part, for this cancer. An on-going multicentre prospective national trial tries to address this question.
