Cancer Stem Cell Marker Bmi‐1 Expression is Associated with Basal‐like Phenotype and Poor Survival in Breast Cancer

Abstract

Bmi-1 status is an independent prognostic factor, which also is associated with tumor histological grade and basal-like phenotype. The high proportions of positive Bmi-1 expression in basal-like breast cancer may be related to the high aggressiveness behavior of this subtype of breast cancer.
