Abstract
Background: Male breast cancer is a rare entity, with an approximate rate of 1.1 / 100 000 in the US, with an average age of 67 years. In all cases a genetic study must be performed, in order to find mutations in known genes, and after the resolution of the disease, based on the results, a contralateral prophylactic mastectomy should be considered.
Clinical case: 53 -year-old male diagnosed with right breast cancer, infiltrating ductal adenocarcinoma type, clinical stage IIB, breast cancer on 2 immediate family history, mutations of the BRCA1 gene and positive hormone receptors and Her2/Neu. He was treated with modified radical mastectomy in diseased side with subsequent neoadjuvant chemotherapy/radiotherapy. After a year of follow-up and a free behavior of disease, contralateral prophylactic mastectomy was performed. The patient progressed satisfactorily, following up to 18 months since the beginning, with no tumor activity data.
Conclusions: Breast cancer in male patient has a worse prognosis than female patients, due to lower amount of tissue in breast exposed to an earlier chest spread and a different biological behavior, also a higher risk of prostate and pancreatic cancer is associated. Studies of adequate methodological quality are scarce, so that decisions are based on guidelines for breast cancer in women.
