Pattern of Recurrence and Survival Outcomes in Non-Metastatic Triple-Negative Breast Cancer; A Retrospective Analysis

Abstract

OBJECTIVE Triple-negative breast cancer (TNBC) is an aggressive heterogeneous cancer and carries poor prognosis. The study was conducted to analyze the recurrence pattern and survival outcome in TNBC patients. METHODS A retrospective analysis was performed for 171 consecutive non-metastatic TNBC patients. Chi-square test, Kaplan-Meier method, and Cox-regression analysis were used for statistical analysis. P nodes (regional+non regional) > brain > bone > liver > contralateral breast. The disease-free survival (DFS) and overall survival (OS) were 64.3% and 78.4%, respectively. High-grade tumor, nodal metastasis,
