In a multivariate analysis of breast cancer cases, the expression of YB-1 was better than HER-2 or ER in predicting reduced BCSS

YB-1 was approximately equal to the power of tumor grade yet not as accurate as tumor size or nodal status in predicting reduced BCSS. BCSS, breast cancer specific survival; CI, confidence interval; ER, estrogen receptor; HER, human epidermal growth factor receptor; HR, hazard ratio; YB-1 = Y-box binding protein-1.
