A Comparative Study of Clinical Profile and Relapse Patterns in TRIPLE-NEGATIVE and NonTriple-Negative Breast Cancer Patients Treated with Curative Intent.

Molecular subtyping in breast cancer is recently emerging as an important determinant of treatment and outcomes, and triple negative breast cancer (TNBC) has been established as a distinct clinical entity with unique features and adverse outcomes. A retrospective analysis of a prospectively maintained computerized breast cancer database was performed, and all the non-metastatic female breast cancer patients undergoing potentially curative multimodality treatment between 2005 and 2012 were included for analysis. Patients with incomplete information regarding ER, PR, and HER2/neu status were excluded.
