The bibliographies of the included studies were searched, too. After study selection, assessment, data collection and analysis were under- taken, we performed this meta-analysis by using the RevMan5.2 software. Seventeen studies involving 1116 patients met the inclusion criteria with 530 treated with RFA-plus-TACE and 586 with TACE alone. The results of meta-analysis showed that the combination of TACE and RFA was obviously as- sociated with higher 1-, 2-, and 3-year overall survival rates （OR1-year=3.98, 95% CI 2.87-5.51, P〈0.00001; OR2-year=3.03, 95% CI 2.10-4.38, P〈0.00001; OR3-year=7.02, 95% CI 4.14-11.92, P〈0.00001） than TACE alone. The tumor complete necrosis rate in patients treated with TACE and RFA was higher than that of TACE alone （OR=13.86, 95% CI 8.04-23.89, P〈0.00001）. And there was a significant difference in local recurrence rate between two different kinds of treatment （OR=0.24, 95%CI 0.14-0.44, P〈0.00001）. Additionally, combination of TACE and RFA was associated with higher complete tumor necrosis rates than TACE mono-therapy in the treatment of HCC. However, RFA plus TACE was found to be associated with a lower local recurrence rate than TACE monotherapy TACE-plus-RFA treatment was associated with a higher response rate （RR） than the TACE-alone treat- ment （OR=3.90, 95% CI=2.37-5.42, P〈0.00001）. TACE-plus-RFA treatment did not differ from the TACE-alone treatment in terms of stable disease （SD） rate （OR=0.38, 95% CI=0.11-1.26, P=-0.11）.
