Abstract:
Objective To analyze the risk factors of hepatocellular carcinoma (HCC) recurrence after liver transplantation based on 18F-FDG PET/CT.Method We respectively analyzed 54 cases of HCC patients who accepted liver transplantation from 2008 September to 2012 November.The clinicopathological features of 54 patients were analyzed by univariate and multivariate analysis to determine the risk factors of HCC recurrence after liver transplantation.The ROC curve was drawn to determine the optimal cutoff value of T/B that affects HCC recurrence after liver transplantation.Result The total incidence of HCC recurrence was 48.1％ (26/54); the disease-free survival (DFS) rate of 0.5 year,1 year and 2 years after transplantation in 54 patients was 92.6％,66.7％,52.2％,49.1 ％ and 49.1％ respectively.The univariate analysis results showed that there were 5 variables to affect HCC recurrence,namely PET imaging,tumor size,tumor number,preoperative AFP level,and tumor degree.On ROC curve analysis,the optimal cutoff value for T/B was 1.69.The multivariate analysis concluded that T/B,and preoperative AFP level were independent factors.Conclusion T/B ＞1.69 and preoperative AFP level ＞400 μg/L are important biological factors of HCC recurrence after liver transplantation.
