Hand-foot skin reaction (HFSR) and overall survival (OS) in the phase 3 RESORCE trial of regorafenib for treatment of hepatocellular carcinoma (HCC) progressing on sorafenib

Skin toxicity is a known adverse effect of multikinase inhibitors, and was shown to be a predictor of OS in patients (pts) with HCC treated with sorafenib (Reig M, 2014). In the RESORCE trial, regorafenib improved OS versus placebo in pts with HCC progressing on sorafenib (HR 0.62, 95% CI 0.50, 0.78; Bruix J, 2017). This retrospective analysis explored whether HFSR with regorafenib was associated with OS in RESORCE.
