Abstract

Background: The aim of this study was to evaluate clinical-pathological parameters with impact on overall survival (OS) in male breast carcinoma (MBC). Methodology: We assessed OS at 5 years and at 10 years respectively, as well as OS according to age, tumor size, microscopic type, histological grade, axillary lymph node status, and molecular profile. Results:Two hundred seventeen cases, with a mean age of 62 (range: 18- 85), right breast involvement (52.53%), invasive carcinoma of no special type (86.63%), G2 histological grade (55.4%), T2 (54.41%), N+ (65.89%) and Luminal A molecular subtype (85.29%) were identified. ER, PR and AR were positive in 89.71%, 83.82% and 93.29% of cases, respectively. HER2 was overexpressed in 8.33% of cases and a high Ki67 proliferation index was present in 75% of cases. The 5-year OS was 67.2%, whereas 10-year OS was 48.5%; OS was 92.7% at 5 years and 73.8% at 10 years in axillary lymph node (LN) negative cases, while OS was 59.7% at 5 years and 41.3% at 10 years in axillary LN positive cases (p=0.003). Conclusions: Age at diagnosis ( 60 years), larger tumor size, presence of LN metastases and absence of oncological treatment are negative factors influencing prognosis, with only axillary LN status (p=0.005) and triple negative molecular profile (p=0.05) being statistically significant unfavorable independent prognostic parameters in a multivariate analysis.
