The prognostic importance of triple negative breast carcinoma

There is a current debate on whether triple negative breast carcinomas (estrogen receptor--ER-negative, progesterone receptor--PR-negative and HER2-negative) have a poor prognosis. Our aim in this retrospective study was to determine whether triple negative feature is a prognostic factor for disease-free survival (DFS) in 322 breast carcinoma patients, of whom 80 (24.8%) had triple negative tumor histology. In the multivariate analysis, tumor subgroup (triple vs non-triple, p<0.0001; hazard ratio [HR], 4.2; 95% confidence interval [95%CI], 2.2-8.2) was a significant factor related to relapse, in addition to number of metastatic nodes (>4 vs
