BRD4 and hepatocellular carcinoma: Consequently, via multivariate survival analysis, BRD4/8/9 expressions were independently associated with worse DFS, and BRD8 was also independently correlated with unfavorable OS, suggesting BRD4/8/9 were promising prognostic factors in HCC patients although BRD4 and BRD9 were not independent predictors of OS in HCC patients.
