[Breast cancer in men: incidence and types of associated previous synchronous and metachronous cancers].
Male breast cancer represents about only 1% of all breast cancers. We have analysed a retrospective, multicentric series of 404 patients, initially non-metastatic, with mean age of 63 years. The 5 and 10-year overall survival rates were 65 and 36% respectively. Sixty-eight patients developed secondary cancer. From ten patients who already presented with cancer (2.5%) 3 cases corresponded to prostatic cancer treated by estrogen. Four had synchronous cancer (1%). Three and eight patients respectively had a synchronous and metachronous contralateral breast cancer (2.7% of bilateral cancer). Forty-three other patients (10.6%) developed metachronous cancer. The main tumor types were: prostate (9), lung (6), colon and rectum (6), esophagus (4). Four patients developed various hematologic malignancies and 14 patients, various types of solid tumors. From these 43 patients, 27 died; 19 as a result of secondary cancer. This represents 9% of all deaths among the 404 patients. While the bilateral cancer rate is similar to women, the second cancer rate appears to be higher in men. From hematological malignancies, chemotherapy and radiotherapy do not seem to contribute to this high incidence of second cancer.
