Prognostic factors of hepatocellular carcinoma survival after radiofrequency ablation: A US population-based study.

Objective: To determine the survival outcome and prognostic factors of hepatocellular carcinoma (HCC) survival in patients who underwent radiofrequency ablation (RFA).

Methods: The Surveillance, Epidemiology and End Results (SEER) database was queried: There were 2588 HCC patients from 2004 to 2012 who underwent RFA. The Kaplan-Meier curves and the multivariate Cox regression analysis were used to assess the prognostic factors.
