Abstract
Male breast cancer is rare. Median age at diagnosis is approximately 65 years, and > 35% of male breast cancers occur in elderly men. Retroareolar lump is the most frequent symptom, and 25-30% of tumours are T(4) lesions. Infiltrating ductal carcinoma represents almost 90% of the cases, and 10% are ductal carcinoma in situ. Axillary nodal involvement is present in 50-60% of the cases. Estrogen and progesterone receptors are positive in 75-92% and 54-77% of the cases. Mastectomy with axillary dissection remains the standard treatment. Sentinel lymph node biopsy could be proposed in small tumours (< or = 2 cm). Locoregional radiotherapy is very often indicated. Tamoxifen is the standard adjuvant treatment, but chemotherapy is proposed in young men with axillary nodal involvement and/or negative hormone receptors. Tumour size and, more particularly, histopathological axillary involvement are the strongest predictive factors for both locoregional recurrence and metastasis. Globally, the prognosis is similar to that in women (at identical stage), but the intercurrent death rate is higher due to the important impact of comorbidities and second neoplasm.Keywords
