Effectiveness of drug-eluting bead transarterial chemoembolization versus conventional transarterial chemoembolization for small hepatocellular carcinoma in Child-Pugh class A patients.

ABSTRACT:

Background

This study aimed to compare the therapeutic effectiveness including progression-free survival (PFS), overall survival (OS), and safety of conventional transarterial chemoembolization (cTACE) and drug-eluting bead transarterial chemoembolization (DEB-TACE) in a superselective fashion for the patients with nodular hepatocellular carcinoma (HCC) (n ⩽ 5) and Child-Pugh class A.

Methods

A total of 198 consecutive patients with nodular HCCs (n ⩽ 5) and Child-Pugh class A liver function who were initially treated with cTACE (n = 125) or DEB-TACE (n = 57) were included retrospectively. The primary endpoint was PFS. Secondary endpoints included time-to-target lesion progression (TTTLP), OS, and safety.

Results

The median follow up was 62 months (range, 1-87 months). The PFS was significantly longer in the cTACE group than in the DEB-TACE group (median, 18 months versus 7 months; hazard ratio [HR] = 0.658, log-rank p = 0.031), whereas OS was comparable (log-rank p = 0.299). TTTLP was significantly longer in the cTACE group than in the DEB-TACE group (median, 34 months versus 11 months; log-rank p < 0.001). In the stratification analysis based on tumor size, the cTACE group showed significantly longer TTTLP than the DEB-TACE group in the 1.0-2.0 cm and 2.1-3.0 cm subgroups (HR = 0.188, log-rank p < 0.001 and HR = 0.410, p = 0.015, respectively) but not in the 3.1-5.0 cm and 5.1-10.0 cm subgroups (all p > 0.05). Postembolization syndrome occurred more frequently in the cTACE group than in the DEB-TACE group (p = 0.006).

Conclusions

DEB-TACE is followed by significantly shorter PFS than cTACE in patients with nodular HCCs (n ⩽ 5) and Child-Pugh class A, although OS is comparable. Postembolization syndrome occurs more frequently in cTACE than in DEB-TACE.

Project description:BACKGROUND:Optimal administration of transarterial chemoembolization (TACE), the standard approach for intermediate-stage hepatocellular carcinoma (HCC), requires clinical and technical expertise. We sought to evaluate whether TACE retains its effectiveness when administered across a broad range of health care settings. Furthermore, as the use of yttrium(90) (Y(90)) radioembolization has been increasing, we explored the comparative effectiveness of Y(90) as an alternative to TACE. METHODS:Patients with HCC diagnosed from 2004 through 2009 treated initially with TACE or Y(90) were identified from the SEER-Medicare linkage. Key covariates included prediagnosis ?-fetoprotein (AFP) screening, complications of cirrhosis, and tumor extent. Effect of treatment, patient, and health care system factors on overall survival (OS) was evaluated using multivariable Cox proportional hazards. Stratified OS estimates are provided. Propensity score (PS) weighting was used to compare effectiveness of Y(90) with TACE. RESULTS:Of 1528 patients who underwent intra-arterial embolization, 577 received concurrent chemotherapy (eg, TACE). Median OS was 21 months (95% CI, 18-23) following TACE and 9 months (95% CI, 1-41) following Y(90). Refined survival estimates stratified by stage, AFP screening, and liver comorbidity are presented. The 90-day mortality rate after TACE was 21% to 25% in patients with extrahepatic spread or vascular invasion. In the PS-weighted analysis, Y(90) was associated with inferior survival, with an adjusted hazard ratio of 1.39 (95% CI, 1.02-1.90). CONCLUSIONS:The effectiveness of TACE is generalizable to Medicare patients receiving care in a variety of treatment settings. However, early posttreatment mortality is high in patients with advanced disease. We found no evidence of improved outcomes with Y(90) compared with TACE. Survival estimates from this large cohort can be used to provide prognostic information to patients considering palliative TACE.

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.
