Objective To compare clinical effect of percutaneous radiofrequency ablation (RFA) and open repeated hepatectomy (ORH) in treatment of liver cancer with late recurrence (recurrence time >12 months) and single tumor diameter ≤5 cm.Methods The patients with advanced intrahepatic recurrence after first operation for liver cancer in this hospital from January 2013 to December 2019 were retrospectively collected, who were treated with ORH (ORH group) or percutaneous RFA (RFA group) and met the inclusion criteria. The overall survival rate and disease-free survival rate of the two groups were compared after 1∶1 matching by propensity score matching (PSM), while the factors affecting survival were stratified.Results A total of 244 patients with recurrent liver cancer were collected, including 134 patients in the ORH group, 110 patients in the RFA group. The patients in the two groups were matched with 1∶1 by PSM, 90 patients in each group. The median overall survival time of the ORH group and the RFA group was 54 months and 45 months, respectively. There were no significant differences in the curves of cumulative overall survival and cumulative disease-free survival between the two groups (P=0.221, P=0.199). The incidence of severe complications in the ORH group was higher than that in the RFA group (10.00% versus 2.22%, P=0.029). A further subgroup analysis showed that the overall survival time of the ORH group was longer than that of the RFA group when the diameter of recurrent liver cancer was 3 to 5 cm (P=0.035), which had no significant differences for the patients with AFP (>400 μg/L or ≤400 μg/L), tumors number (single or multiple), and tumor diameter ≤3 cm between the two groups (P>0.05).Conclusions Percutaneous RFA is effective and safe in treatment of advanced recurrent liver cancer, its overall survival and disease-free survival are similar to ORH treatment. However, when diameter of recurrent tumor is3–5 cm, ORH treatment has a advantage in prolonging survival time of patients.
