    ObjectiveTo evaluate the efficacy of radiofrequency ablation for the treatment of postoperative recurrence of hepatocellular carcinoma and whether radiofrequency ablation can be used as first line treatment for recurrent hepatocellular carcinoma.MethodsThere were 213 patients with small recurrent hepatocellular carcinoma (tumor size of 3 cm or less and no more than 3 nodules) who treated in Liver Cancer Institute, Fudan University from January 2000 to December 2005. Among these patients 68 were treated with radiofrequency ablation and 145 were treated with repeated surgical resection. Kaplan-Meier method was used to evaluate the overall survival or disease free survival. Log-rank used to determine the survival difference between groups and COX proportional hazard was used for multivariate analysis to evaluate the risk factors for prognosis. The overall survival or disease free survival was calculated from the time treated with radiofrequency or repeated surgical resection.ResultsThe 1-, 3-, 5-years overall survival rates were 94.7%, 65.1%, 37.3% and 88.1%, 62.6%, 41.0% in radiofrequency ablation group and surgical repeated resection group, respectively. There was no significant difference between two groups (P = 0.693). However, the disease free survival was better in repeated surgical resection than in radiofrequency ablation, which were 79.4%, 48.1%, 34.4% and 58.0%, 27.8%, 12.4% in repeated surgical resection and radiofrequency ablation, respectively (P = 0.001). The interval between recurrence and initial hepatectomy with more than 2 years was independent factor favor to good prognosis.ConclusionsRadiofrequency ablation seems to be as effective as repeated surgical resection owing to comparable overall survival and can be considered as alternative therapy for surgical resection treatment of small recurrent hepatocellular carcinoma.
