RESUMEN

To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) and TACE alone for hepatocellular carcinoma (HCC), Pubmed, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Datebases were searched for the randomized controlled trials (RCTs) and retrospective cohort studies from the establishment of the databases to January 2014. The bibliographies of the included studies were searched, too. After study selection, assessment, data collection and analysis were undertaken, 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 associated 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 treatment (OR=3.90, 95% CI=2.37-6.42, 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). Meta-analyses showed that the combination of RFA and TACE was associated with a significantly lower progressive disease (PD) rate (OR=0.15, 95% CI=0.05-0.43, P=0.0005). The rate of AFP reducing or returning to normal in serum in RFA plus TACE group was obviously lower than TACE alone group (OR=4.62, 95% CI 2.56-8.34, P<0.00001). The effect of TACE plus RFA for HCC is better than TACE mono-therapy. The combined therapy can elevate the patients' overall survival rate, tumor necrosis rate and the rate of AFP reducing or returning to normal in serum and decrease local recurrence rate, PD rate compared with TACE alone.

RESUMEN

<p><b>OBJECTIVE</b>To explore the therapeutic efficacy of a combined treatment modality using transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) to treat hepatocellular carcinoma (HCC) complicated with main branch intraportal vein tumor thrombosis (PVTT).</p><p><b>METHODS</b>Clinical data was collected retrospectively for patients diagnosed with and treated for HCC plus main branch PVTT at our hospital between January 2007 and January 2010. The total study population (n = 51) consisted of 38 males and 13 females, with an average of 50.1 years (range: 24-73). Among these patients, 26 had been treated with TACE + PEI (group A) and 25 had been treated with TACE alone (group B). Short-term changes in PVTT (i.e. disappearance, shrinkage, and/or stability) and tumor (i.e. complete response, partial response, and/or stable disease) were assessed by using the t-test (continuous variables) or the Chi-squared or Fisher's exact tests (categorical variables). Between-group differences in survival time were assessed by the Kaplan-Meier analysis and log-rank test.</p><p><b>RESULTS</b>The follow-up time ranged from 3-24 months after treatment, and no serious treatment-related complications were recorded for any of the patients (0/51). The time of TACE treatment was significantly longer for the patients receiving the combination therapy (group A: 3.21.4 vs. group B: 2.40.9, t = 2.22, P = 0.032). The patients in group A received between 2-8 PEI treatments. The TACE + PEI combined treatment showed significantly better therapeutic efficacy for PVTT (group A: 19/26 vs. group B: 10/25, X2 = 5.685, P = 0.019). The tumor response was significantly better in patients treated with TACE + PEI at post-treatment month 3 (group A: 20/26 vs. group B: 18/25, X2 = 0.163, P = 0.705) and month 6 (group A: 17/20 vs. 10/19, X2 = 2.58, P = 0.027). Finally, the average survival time was significantly better in patients treated with TACE + PEI (group A: 12.856.02 months (range: 5-23) vs. group B: 8.653.39 months (range: 4-16), t = 3.051, P = 0.004).</p><p><b>CONCLUSION</b>TACE + PEI combination therapy for main branch PVTT in HCC patients is more efficacious than TACE alone, and is associated with a longer survival time.</p>
