From: Impact of follow-up interval on patients with hepatocellular carcinoma after curative ablation
The OS and RFS curves with 95% CIs and risk tables and the recurrence patterns for all HCC patients treated with ablation. a The RFS of 616 patients. The 1, 2- and 5-year RFS rates were 68.9, 46.9 and 19.3%, respectively. b The OS of 616 patients. The1-, 2- and 5-year OS rates were 98.2, 91.8 and 72.7%, respectively. c The probability density plot of recurrence showed that relapse cases centered in the first 2 years after ablation. d The hazard rate of recurrence curve showed that the recurrence hazard peaked during the first 2 years after ablation
