Prognostic relevant fators of liver transplantation in adults with hepatocellular carcinoma: a retrospective analysis / 中华器官移植杂志

ABSTRACT

Objective To investigate the prognostic relevant factors of hepatocellular carcinoma (HCC) in recipients following liver transplantation (LT).Methods The clinical data of 147 cases of HCC undergoing LT between Aug. 2004 and Feb. 2011 in Nanfang Hospital were studied retrospectively.Those of significance in 14 relevant factors involving gender,age,blood-type,CTP,model of end-stage liver disease (MELD),alpha-fetoprotein (AFP),tumor number,cumulative diameter of tumor,tumor occupying proportion of the liver,bilobar involvement,envelope invasion,macrovascular invasion,and microvascular invasion (MVI),HCC histology differentiation,which were based on univariate analysis with Log-Rank,were analyzed by means of Multivariate Cox proportional hazard regression model to screen out independently relevant ones.Results 143 cases were followed up.The follow-up duration ranged from 6 to 84 months.The 1- and 3-year cumulative survival rate was 75.2％ and 54.7％ respectively.The tumor free 1- and 3-year cumulative survival rate was 70％ and 59％ respectively.Univariate ananlysis revealed that age,AFP,tumor number,cumulative diameter of tumor,tumor occupying proportion of the liver,bilobar involvement,envelope invasion,macrovascular invasion,and MVI had significant difference, In a Cox model,MVI,macrovascular invasion and AFP≥ 400 μg/L were independent prognostic factors.Conclusion MVI,macrovascular invasion and AFP are the main prognostic risk fators.Intervention and non-tumor technique should be performed preoperatively and intraoperatively,respectively.
