Immunohistochemical profiling studies carried out on female breast cancer has been extrapolated to breast cancer in males. Although, we do not know if it really reflects the reality of this pathology in males patients since the studies are often retrospective and studying a limited number of patients. The objectives was to describe particualrities of breast cancer in males and analyze the evolutionary characteristics and study the molecular profile of this rare disease in Tunisian men. It is a retrospective, descriptive and analytic study carried out over a period of 15 years in the departments of gynecology-obstetrics, general surgery, medical carcinology and anatomopathology of the Farhat Hached Teaching Hospital in Sousse, Tunisia. Fourty five patients were included.The most common histological type was invasive ductal carcinoma (95% of our patients). Our series was divided into 3 immunohistochemical groups with a majority group: luminal A (68.2%), followed by luminal B (27.3%) and only one patient had a triple negative type tumor (4.5%).The Overall survival rate (OSR) at 5 and 10 years was 83.2% and 76.8% respectively. Recurrence-free survival (RFS) at 5 and 10 years was 64.5% and 58.6%, respectively. The OSR was influenced significantly by age, clinical and histological size of the tumor, the presence of distant metastases and the occurrence of recurrence. Recurrence-free survival (RFS) was influenced by age, clinical and histological size of the tumor, and infiltration of the dermis. Breast cancer in males has similarities with women's breast cancer. However, it remains diagnosed at a later stage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
