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

Table 4

Time to recurrence after curative resection predictive value of OS and RFS using different cut-off values.

Cut-off values of time to recurrence after curative resection (months)	Log-rank analyses for OS, value^1	Log-rank analyses for RFS, value^1
4	0.636	0.001
6	0.380	<0.001
9	0.006	<0.001
12	0.013	0.001
18	0.083	<0.001
24	0.089	0.002
36	0.683	0.004

OS: overall survival; RFS: recurrence-free survival; ¹log-rank test.
