Cumulative RFS rate without LC. The PC group contained eight patients with LC and the SR group contained 19 patients with LC. The corresponding RFS rates at one, three and five years after PC and SR were 87.50, 50.00 and 37.50%, respectively, in the PC group without LC and 84.2, 57.89 and 36.84%, respectively, in the SR group without LC. There were no significant differences between these two groups, as determined using the log-rank test (P=0.819). RFS, recurrence-free survival; LC, liver cirrhosis; PC, percutaneous cryosurgery; SR, surgical resection.
