Extrapolating Prognostic Factors of Primary Curative Resection to Postresection Recurrences Hepatocellular Carcinoma Treatable by Radiofrequency Ablation

Table 2

Multivariate analysis of the factors associated with OS of recurrent HCC patients undergoing RFA.

Risk factor	Hazard ratio	95% CI	value^1
Tumor differentiation (>II), yes/no	1.878	1.077-3.275	0.026
Time to recurrence after curative resection (≤9 months), yes/no	1.828	1.066-3.135	0.028
GGT (>50 IU/l), yes/no	2.186	1.271-3.760	0.005
AFP (>20 ng/ml), yes/no	1.929	1.133-3.284	0.016

OS: overall survival; RFA: radiofrequency ablation; CI: confidence interval; GGT: γ-glutamyltranspeptidase; AFP: alpha-fetoprotein; ¹Cox proportional hazard model.
