Transarterial chemoembolization in combination with local therapies for hepatocellular carcinoma: a meta-analysis.

ABSTRACT: BACKGROUND: In previous randomized trials, transarterial chemoembolization (TACE) has shown an improvement of survival rate in hepatocellular carcinoma (HCC) when combined with radiofrequency ablation (RFA), percutaneous ethanol injection (PEI) or other therapies. The aim of this meta-analysis was to evaluate the effectiveness of combination therapy of TACE with RFA, PEI, radiotherapy (RT), three-dimensional conformal radiation therapy (3D-CRT) or High-Intensity Focused Ultrasound (HIFU). METHODS: Randomized or nonrandomized studies comparing TACE combined with RFA, PEI, RT, 3D-CRT or HIFU with TACE alone for HCC were included. Meta-analysis was performed using a fix-effects model in RCTs and a random-effects model among the observational studies. RESULTS: 10 randomized trials and 18 observational studies matched the selection criteria, including 2497 patients (682 in RCTs, 1815 in non-RCTs). Meta-analysis of RCTs showed that the combination of TACE and PEI ((RR)(1-)year=1.10, 95%CI=0.99-1.22, p=0.073; (RR)(3-)year=2.32, 95%CI=1.52-3.53, p<0.001), TACE+RT ((RR)(1-)year=1.37, 95%CI=1.11-1.70, p=0.004; (RR)(3-)year=2.32, 95%CI=1.44-3.75, p=0.001) were associated with higher survival rates. The results of observational studies were in good consistency with that of RCTs. Furthermore, TACE plus 3D-CRT ((RR)1 -year=1.22, 95%CI=1.06-1.41, p=0.005; (RR)(3-)year=2.05, 95%CI=1.48-2.84, p<0.001) and TACE plus HIFU ((RR)(1-)year=1.16, 95%CI=1.01-1.33, p=0.033; (RR)(3-)year=1.66, 95%CI=1.12-2.45, p=0.011) have introduced marked survival benefit when pooling results from observational studies. CONCLUSIONS: This meta-analysis demonstrated that TACE combined with local treatments, especially PEI, HIFU or 3D-CRT could improve the overall survival status than performing TACE alone. Importantly, these results need to be validated in further high-quality clinical trials.

Project description:BackgroundDrug-eluting embolic transarterial chemoembolization (DEE-TACE) is an advance in TACE technique. However, at present there is insufficient evidence to support that DEE-TACE is superior to conventional TACE (cTACE) for hepatocellular carcinoma (HCC). The aim of this meta-analysis is to evaluate the efficacy and safety of TACE with CalliSpheres® microspheres (CSM-TACE) compared with cTACE in patients with HCC.Data sourcesPubMed, Embase, Web of Science, CNKI and Wanfang Databases were searched to identify relevant articles published before March 26, 2020. The data regarding treatment response, survival profile, adverse events and liver function indexes were retrieved.ResultsA total of 16 studies with 1454 HCC patients (722 treated with CSM-TACE and 732 with cTACE) were included. Patients receiving CSM-TACE had higher 1-month complete response (CR), objective response rate (ORR), disease control rate (DCR) (odds ratio (OR): 2.00, 95% confidence interval (95% CI): 1.29-3.09; OR: 2.87, 95% CI: 2.15-3.83; OR: 2.01, 95% CI: 1.37-2.95, respectively), 3-month CR, ORR, DCR (OR: 4.04, 95%CI: 2.46-6.64; OR: 3.39, 95%CI: 2.45-4.70; OR: 1.71, 95%CI: 1.14-2.55 respectively), and 6-month CR, ORR, DCR (OR: 4.02, 95%CI: 2.26-7.16; OR: 3.00, 95%CI: 2.05-4.38; OR: 2.66, 95%CI: 1.70-4.16 respectively) than those treated with cTACE. Furthermore, CSM-TACE exhibited a trend toward improved progression free survival (hazard ratio (HR): 0.86, 95%CI: 0.67-1.11) and overall survival (HR: 0.79, 95%CI: 0.59-1.07) over cTACE although these differences did not reach statistical significance. In terms of safety, the two TACE treatments showed similar post-treatment pain (OR: 0.84, 95%CI: 0.55-1.28), fever (OR: 0.99, 95%CI: 0.60-1.63), nausea/vomiting (OR: 0.84, 95% CI: 0.60-1.17), as well as 1-month follow-up alanine aminotransferase (Mean difference (MD): -3.66, 95%CI: -10.38-3.07), aspartate aminotransferase (MD: -2.30, 95%CI: -8.91-4.31) and total bilirubin (MD: -0.15, 95%CI: -2.26-1.96).ConclusionCSM-TACE displays superior treatment response, non-inferior survival profile and safety over cTACE in HCC patients.

Project description:BACKGROUND:Transarterial chemoembolization (TACE) is the recommended treatment for hepatocellular carcinoma (HCC) patients at Barcelona Clinic Liver Cancer (BCLC) B-stage, whereas sorafenib is an orally administered small molecule target drug for BCLC C-stage. This updated systemic review and meta-analysis focuses on identifying the efficacy of the combination of TACE with sorafenib, which remains controversial despite years of exploration. METHODS:PubMed, EMBASE, Scopus and the Cochrane Library were systematically reviewed to search for studies published from January 1990 to May 2017. Studies focusing on the efficacy of combination therapy for unresectable HCC were eligible. The hazard ratio (HR) with 95% confidence intervals (95% CIs) for time to progression (TTP), overall survival (OS), disease control rate (DCR) and aetiology were collected. The data were then analysed through fixed/random effects meta-analysis models with STATA 13.0. The incidence and severity of treatment-related adverse events (AEs) were also evaluated. RESULTS:Twenty-seven studies were included. Thirteen non-comparative studies reported median OS (ranging from 18.5 to 20.4 months), median TTP (ranging from 7 to 13.9 months) and DCR (ranging from 18.4 to 95%). Fourteen comparative studies provided median OS (ranging from 7.0 to 29.7 months) and median TTP (ranging from 2.6 to 10.2 months). Five comparative studies provided DCR (ranging from 32 to 97.2%). Forest plots showed that combination therapy significantly improved TTP (HR?=?0.66, 95% CI 0.50-0.81, P?=?0.002) rather than OS (HR?=?0.63, 95% CI 0.55-0.71, P?=?0.058), compared to TACE alone. DCR increased significantly in the combination therapy group (OR?=?2.93, 95% CI 1.59-5.41, P?=?0.005). Additional forest plots were drawn and no significant differences were observed with regard to survival outcome among various aetiologies. Forest plots for separate analysis of regions showed the HR for TTP was 0.62 (95% CI 0.45-0.79, P?=?0.002) in the Asian countries group, and 0.82 (95% CI 0.59-1.05, P?=?0.504)) in western countries. The HR for OS was 0.61 (95% CI 0.48-0.75, P?=?0.050) in the Asian countries group and was 0.88 (95% CI 0.56-1.20, P?=?0.845) in western countries. These data may indicate positive TTP outcome in Asian patients but not in European patients while no positive findings regarding OS were observed in either region. The most common AEs included fatigue, hand-foot skin reaction, diarrhoea and hypertension. CONCLUSIONS:Combination therapy may benefit unresectable HCC patients in terms of prolonged TTP and DCR. More well-designed studies are needed to investigate its superiority for OS.
