KRT19 and neoplasm: A Cox-Regression showed that alcohol (p=.026, Exp(B)=1.666, 95% CI 1.098-3.069) and tumor grading (p=.024, Exp(B)=1.916, 95% CI 1.0601-3.049) were significant predictors for the differences in OS between patients with positive and patients with negative CK19 immunoreactivity, whereas in DSS no demographic or prognostic factor was a statistically significant risk factor.
