Breast Cancer in Men: Characteristics Epidemiological, Clinicopathological and Therapeutic

Background: Breast cancer is the leading malignancy in women, but it is relatively rare in men, accounting for 1% of all breast cancers. In Morocco, its incidence is 0.8/ 100,000 in men. This condition epidemiology, therapeutic and prognostic remains unknown given the scarcity of reported series. The objective of this work is to identify the epidemiological, clinical, pathological and therapeutic of this cancer in men. Results: Six patients were diagnosed with breast cancer with a ratio of 6/1277 cases. The mean age of patients was 63.3 ± 9.7 ans; the most common histological type was invasive ductal carcinoma (83.3%). The grade 2 SBR has a majority (66.7%), while that of SBR 3 is less represented (33.3%). A positive estrogen receptor (66.7% of cases) and progesterone (50.0% of cases) was noted. The HER2 receptor is overexpressed in 25% of cases. The treatment was essentially surgical (83.3%). Additional treatment included adjuvant chemotherapy (50.0%), radiotherapy (50.0%) and hormonal therapy (16.7%) was administered. Discussion/Conclusion: Breast cancer in men is rare and appears to have a very close clinical, histological characteristics and prognosis to those of elderly women. The diagnosis is usually late and tumors are treated in advanced stages. An improved prognosis requires better awareness for early detection.
