RESUMO
OBJECTIVE: To observe the safety and efficacy of rehepatectomy and radiofrequency ablation for patientswith recurrent hepatocellular carcinoma(HCC).METHODS: A consecutive sample of 159 recurrent HCC patients whounderwent rehepatectomy(n=77) or radiofrequency ablation(n=82) from January 2005 to December 2014 were analyzedretrospectively. Propensity score analysis was used. The Kaplan-Meier method was used for survival analysis.RESULTS: Propensity score analysis chose 41 pair patients. Patients in the radiofrequency ablation group were with lower rate ofperioperative mortality and morbidiy,shorter length of hospital stay. When calculate the survival time from the date ofrehepatectomy or radiofrequency ablation,or calculate the survival time from the date of the first hepatectomy,the twoarms showed similar overall survival(P=0.258,0.820). Moreover,overall survival were similar after propensity scoreanalysis(P=0.443,0.917).CONCLUSION: Radiofrequency ablation was safety,associated with shorter length of hospitalstay and similar long-term overall survival with rehepatectomy for recurrent HCC.
