Abstract BACKGROUND: Infiltrating MBC represents less than 1\% of all male cancers. Our study details clinico-pathological features, treatments and prognostic factors in a large French cohort. MATERIAL AND METHODS: Four hundred and eighty-nine patients were collected from 1990 to 2005. Median age was 66 years (34\% over 70 years) and median follow-up 58 months. RESULTS: According to TN classification, we found T(1): 39\%, T(2): 41\%, T(3)T(4): 9\%, T(x): 11\% and N(1)N(2): 27\%. Lumpectomy (L) and mastectomy (M) were performed in 8.6\% and 91.4\% of the cases. Axillary dissection (AD), sentinel node biopsy or both were performed in 90\%, 2\% and 5\% of the cases, respectively. Ninety-five percent of tumours were ductal carcinomas; 47\% were pT(1), 20\% pT(2) and 33\% pT(3)-T(4). Axillary nodal involvement was present in 52.8\% cases. ER and PgR were positive in 92\% and 89\% cases. Radiotherapy (RT) was performed in 85\% of the patients. Hormonal treatment (HT) was delivered in 72\% of the cases. Tamoxifen and aromatase inhibitors were used in 85\% and 12\% of the cases; 34\% of the patients received chemotherapy (CT). Local recurrence (LR), nodal recurrences (NR) and metastases occurred in 2\%, 5\% and 22\% of the cases; 2\% and 10\% developed contralateral BC and second cancer. The 5- and 10-year overall survival (OS) rates were 81\% and 59\%; disease-specific survivals (DSS) were 89\% and 72\%. Death causes were BC 56\%, second cancer 8\%, complications 3\%, intercurrent disease 15\% and unknown 18\%. In a univariate analysis, metastatic risk factors were T stage (T1: 19\%, T(2): 26\%, T(3)T(4): 40\%; p=0.013), pN status (pN(0): 12\% pN(1-3): 26\% pN(>3): 44\%; p<0.0001) and presence of locoregional recurrence (62\% versus 18\% p<0.0001). In a multivariate analysis, axillary nodal involvement and high SBR remain prognostic factors. CONCLUSION: Earlier diagnosis and wide use of adjuvant treatments (RT/HT/CT) widely decreased LR and increased survival rates in MBC, reaching female ones. Prognostic factors were also very similar to female ones. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.
