Despite a significant correlation between UCA1 expression and HCC disease-free survival both in univariate and in multivariate regression analyses, the extent of the association by Kaplan-Meier event analysis with log rank method showed no significance (mean survival time, high = 50.17 ± 4.71 and low = 52.92 ± 4.64 months, resp.; log rank P = 0.616, Figure 2(C)). Here, UCA1 is linked to hepatocellular carcinoma.
