The purpose of this study was to investigate the biological behavior of male breast cancer. We evaluated 11 cases of male breast cancer with respect to tumor growth, extent of disease, hormone receptor status, and histological grade of the malignancy, in comparison with 241 cases of female breast cancer. The duration of symptoms was 8.6 +/- 9.1 months in males and 8.5 +/- 18.6 months in females. The incidences of stages I, II, and III were 46%, 27%, and 27%, respectively, in male breast cancer, and 38%, 49%, and 13% in female breast cancer. Metastasis to the lymph node was negative in 60% of the male patients and 54% of the female patients. All cases of male breast cancer were histologically grade I according to Bloom's classification; the histological grades were as follows for the female breast cancer cases: grade I in 99 patients, grade II in 87, and grade III in 55. The rates of hormone receptor positively were 89% for ER and 86% for PgR in male breast cancer, and 64% for ER and 44% for PgR in female breast cancer. Therefore, there was no significant difference in the growth of male breast cancer and female breast cancer, but in male breast cancer the rate of hormone receptor positivity was high, endocrine therapy was effective, and the histological grade was low. Accordingly, the result following appropriate treatment of male breast cancer should be at least comparable to the results with female breast cancer.
