Abstract

BACKGROUND/AIM: Uniform treatment of hepatocellular carcinoma (HCC) with molecular targeted drugs (e.g., sorafenib) results in a poor overall tumor response when tumor subtyping is absent. Patient stratification based on actionable gene expression is a method that can potentially improve the effectiveness of these drugs. Here we aimed to identify the clinical application of actionable genes in predicting response to sorafenib.

METHODS: Through quantitative real-time reverse transcription PCR, we analyzed the expression levels of seven actionable genes (

RESULTS: The responders had significantly higher TBS values than the nonresponders. With an area under the curve of 0.779, a TBS combining

CONCLUSIONS: Our findings on patient stratification based on actionable molecular subtyping potentially provide a therapeutic strategy for improving sorafenib's effectiveness in treating HCC.
