10733 Background: Male breast is an uncommon disease, accounting for <1% of all malingnancies in the man. In contrast to women with breast cancer, men with breast cancer are older and have more advanced disease. Methods: Data regarding 25 male patients who underwent surgery for breast cancer in the our Istitution between January 1994 and December 2005 were analyzed. The main characteristics of these patients included: median age 64 years (range 32–87); positivity family cancer history: specific 4 pts, non-specific 3, no circumstance 18; risk factors: obesity 6 pts, gynaecomastia 4, diabetes 5, liver transplant 1. Five cases of second neoplasia were observed: 2 patient with prostate cancer, 1 synchronous colon carcinoma, 1 head and neck cancer, 1 pancreatic cancer. Results: All but one pts (with syncrhronous metastases at presentation) underwent mastectomy. Pathological characteristics included: pT1 tumors 3 pts (12%); pT2 7 pts (28%), pT3 2 (8%), pT4 13 (52 %); infiltrating ductal carcinomas in 88% of cases; axillary lymph node involvement in 12 (50%); 22 patients had estrogen- and progesterone-receptor positive tumors, 2 pts negative, 1 pts unknown. After surgery 14 pts received RT, 13 pts hormonotherapy and 16 patients adjuvant chemotherapy (7 CMF, 9 anthracyclin-based therapy). Median disease free survival was 41.5 months (range 5–116).With a median follow-up of 66 months, we observed 12 deaths (10 pts for progressive disease) and the overall survival rate was 52% (13 pts; 11 disease-free). According to the family cancer history we observed 5/7 (71%) and 7/18 (39%) deaths in positive and negative cases, respectively. Conclusions: The approach to male breast cancer patients is similar to that for female patients. Our data confirm the suspected epidemiologic risk factors such as prostate cancer, gynecomastia and dietary factors; furthermore, cases with family cancer history seems to have a worse prognosis.
