Abstract
Classical prognostic factors of breast cancer are correlated to disease-free survival and overall survival (OS); their precise role is less known on metastatic disease. A total of 511 breast cancer patients without initial metastasis were treated. OS was divided in time to distant recurrence and metastatic survival (MS). Age, Scarff-Bloom-Richardson (SBR) grade, hormone receptor, axillary node involvement, and Nottingham prognostic index predicted MS in univariate analysis. Multivariate analysis retained age, SBR grade, and axillary lymph node involvement as significant independent prognostic factors. Interactions are still present between initial parameters and MS. The clinician has to take into account for treatment choice.
