VINCI is a unique database for cross sectional and longitudinal analysis. The objective of this retrospective analysis was to compare characteristics and outcome of MBC with FBC in veterans. Methods: Detailed demographics, diagnosis, treatment and outcome of all patients diagnosed with breast cancer between 1998 and 2016 at 152 VA medical centers were obtained and analyzed with Chi-square and t-test univariate statistics. Results: In total 9765 patients' records were reviewed, 1613 MBC were compared with 8152 FBC. The mean age at diagnosis is 68.5 and 57.3 years for MBC and FBC, respectively (Table1). After a median follow up of 3.5 years, 48% MBC and 22% FBC died. Breast cancer mortality is 18% and 9% in MBC and FBC, respectively. A cox regression survival analysis indicates that males were 33% (Hazard Ratio 1.33, P=<0.0001) more l...
