Abstract
1 min readAbstract Background/Aim: Hepatocellular carcinoma patients (HCC) related with non-alcoholic steatohepatitis (NASH) has been recently reported to be not responsive to immune-checkpoint inhibitor treatment (ICI). This study aimed to evaluate therapeutic efficacy in non-alcoholic fatty liver disease (NAFLD)/NASH-related unresectable-HCC (u-HCC) treated with lenvatinib.Material/Methods: Five-hundred-thirty u-HCC with Child-Pugh A were enrolled, and divided into the NAFLD/NASH (n=103) and Viral/Alcohol (n=427) groups. Clinical features were compared in a retrospective manner.Results: Progression-free survival (PFS) was better in the NAFLD/NASH than the Viral/Alcohol group (median 9.3 vs. 7.5 months, P=0.012), while there was no significant difference in overall survival (OS) (20.5 vs. 16.9 months, P=0.057). In Cox-hazard analysis of prognostic factors for PFS, elevated AFP (≥400ng/mL) (HR1.294, P=0.014), elevated ALT (≥30 U/L) (HR1.247, P=0.029), modified ALBI grade 2b (HR1.236, P=0.047), and NAFLD/NASH etiology (HR0.763, P=0.036) were significant prognostic factors. NAFLD/NASH etiology was not a significant prognostic factor in Cox-hazard analysis for OS (HR0.750, P=0.076), whereas AFP (≥400ng/mL) (HR1.402, P=0.009), later line use (HR0.737, P=0.0137), BCLC C stage (HR1.297, P=0.035), and modified ALBI grade 2b (HR1.875, P<0.001) were significant.Conclusion: ICI is reportedly not effective for NAFLD/NASH-related HCC, while lenvatinib can improve the prognosis of u-HCC irrespective of HCC etiology or its line of treatment.
