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

Table 3

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

Risk factor	Hazard ratio	95% CI	value^1
Tumor differentiation (>II), yes/no	1.497	1.022-2.192	0.038
Time to recurrence after curative resection (≤9 months), yes/no	2.400	1.687-3.414	<0.001
GGT (>50 IU/l), yes/no	1.496	1.050-2.133	0.026
Tumor number, multiple/single	1.681	1.075-2.628	0.023

RFS: recurrence-free survival; RFA: radiofrequency ablation; CI: confidence interval; GGT: γ-glutamyltranspeptidase; ¹Cox proportional hazard model.
