BREAST CANCER IN MEN IN THE REPUBLIC OF BASHKORTOSTAN

Abstract

Breast cancer in men is 100 times less common than in women. The principles of treatment of breast cancer in men are still based on knowledge obtained during the treatment of women with a similar pathology. The article reviews 67 cases of all breast cancer stages in men. The majority (50.7%) of all patients who initiated therapy had stage III-IV tumors. In most cases, the patients had an infiltrating ductal carcinoma (52.2%). The combination and complex treatment methods accounted for 53.6% of all cases. The radical mastectomy (89.6%) was the most frequent method of operative intervention. 29 patients (43.3%) received preoperative chemotherapy. 36 patients received adjuvant treatment. The adjuvant treatment comprised chemotherapy (29 patients), and subsequently was supplemented with antihormonal therapy in patients with receptor-positive tumors. The anthracycline-containing chemotherapy was the most prevalent among treatment regimens (72.4%). In 7 patients with a locally diffused process, the treatment was supplemented with radiotherapy. 72.2% of patients had a clinically significant estrogen receptor (RE) expression in the tumor and 61% of patients had a progesterone receptor (RP) expression. 85.0% of patients with stages I-IIA breast cancers showed the relatively high 5-year survival rates, and 67.5% of patients with stage IIB cancers showed 5-year survival. The survival rates for stages III and IV cancer were 18.1% and 16.6%, respectively.
