Impact of resection and ablation for single hypovascular hepatocellular carcinoma ≤2 cm analysed with propensity score weighting

Background and Aims Small hypovascular hepatocellular carcinoma ( HCC ) ≤2 cm is biologically less aggressive than hypervascular one, however, the optimal treatment is still undetermined. The efficacy of surgical resection ( SR ), radiofrequency ablation ( RFA ) and percutaneous ethanol injection ( PEI ) was evaluated. Methods The 853 ( SR , 176; RFA , 491; PEI , 186) patients were enrolled who met Child‐Pugh A/B, single hypovascular HCC ≤2 cm...
