Transarterial Chemoembolization within First 3 Months of Sorafenib Initiation Improves Overall Survival in Hepatocellular Carcinoma: A Retrospective, Multi-Institutional Study with Propensity Matching.

ABSTRACT: PURPOSE:The impact of transarterial chemoembolization after initiation of sorafenib (SOR) has not been prospectively compared with SOR alone in unresectable hepatocellular carcinoma (HCC). The objective of this study was to assess whether SOR + transarterial chemoembolization provides benefit over SOR alone in this setting. MATERIALS AND METHODS:A retrospective cohort study with propensity matching using data from patients prescribed SOR for HCC at Veterans Health Administration hospitals from 2007 to 2015. The primary outcome was overall survival from the time of SOR prescription and stratified by receipt of transarterial chemoembolization within 90 days of SOR initiation. RESULTS:A total of 4,896 patients received SOR for HCC, of whom 232 (4.7%) underwent transarterial chemoembolization within 90 days. Patients receiving transarterial chemoembolization + SOR were highly selected, being younger and with less significant hepatic dysfunction, earlier Barcelona Clinic Liver Cancer stage (P < .0001), and fewer tumors with lower rates of macrovascular invasion (MVI) and metastases (all P < .0001) than SOR-alone patients. In unadjusted analysis, SOR + transarterial chemoembolization was associated with reduced mortality (hazard ratio [HR] 0.61, 95% confidence interval [CI] 0.53-0.71; P < .0001). After propensity matching, SOR + transarterial chemoembolization continued to show significant associations with reduced mortality with HR 0.75 (95% CI 0.62-0.92; P = .0005). Subgroup analysis suggests that the addition of transarterial chemoembolization to SOR improves outcomes in most patients, particularly those with Model for End-Stage Liver Disease score <15, platelets >50,000/?L, and >3 tumors with or without macrovascular invasion, without local invasion or metastases. CONCLUSIONS:Patients with unresectable HCC started on systemic therapy with SOR appear to benefit from adjuvant transarterial chemoembolization. Optimal application of multimodal therapy in this setting should be prospectively investigated.

Project description:AimsThe purpose of the present study was to compare the efficacies of transarterial chemoembolization (TACE) combined with sorafenib versus TACE monotherapy for treating patients with advanced hepatocellular carcinoma (HCC).MethodsWe enrolled 321 patients and selected 280 with advanced HCC (Barcelona Clinic Liver Cancer stage C) who underwent TACE therapy between February 2009 and February 2013. TACE alone (monotherapy group) was administered to 198 patients (70.7%), and the remaining 82 (29.3%) underwent repeat combined TACE and sorafenib therapy (combined group). To minimize selection bias, these latter 82 patients were matched using propensity-score matching at a 1∶2 ratio with 164 patients who received TACE monotherapy. The primary endpoints were overall survival (OS) and related subgroup analysis. The secondary endpoints were time to progression (TTP) and treatment-related adverse events.ResultsOf the respective patients in the combined and monotherapy groups, 64.6% and 49.2% had vascular invasion, 87.8% and 91.1% had extrahepatic metastasis, and 54.3% and 47.1% had both. In the propensity-score-matched cohort, the OS survival of the combined group was significantly higher compared with the monotherapy group (7.0 months vs. 4.9 months, respectively, P = 0.003). The TTP was significantly longer in the combined group (2.6 months vs. 1.9 months, respectively, P = 0.001). Subgroup analysis showed that the outcomes of patients with advanced HCC without main portal vein invasion who were treated with combined therapy were significantly better compared with those who received monotherapy (P<0.05). Univariate and subsequent multivariate analyses revealed that the addition of sorafenib was an independent predictor of favorable OS and TTP (adjusted hazard ratios, 0.63 and 0.62, respectively; P<0.05 for both).ConclusionSorafenib plus TACE was more effective than TACE monotherapy for treating patients with advanced HCC without main portal vein invasion. Future trials with larger samples are required to validate these preliminary findings.

Project description:BackgroundThe combination of tyrosine kinase inhibitors (TKIs) and transarterial chemoembolization (TACE) fulfills an important role in the treatment of unresectable hepatocellular carcinoma (uHCC). Among the combination therapies, both lenvatinib and sorafenib combined with TACE are recommended as first-¬line treatments for uHCC. However, at present, limited data are available concerning the efficacy and safety of these two combination therapies in uHCC.MethodsA detailed systematic search for studies on lenvatinib plus TACE (LEN+TACE) and sorafenib plus TACE (SOR+TACE) was conducted in the online databases PubMed, Embase and The Cochrane Library. The outcome data including overall survival (OS), progression free survival (PFS), time to progression (TTP), tumor response and adverse events (AEs), were independently extracted by two authors in a standardized way.ResultsOne randomized controlled trial and five cohort studies with 598 patients (LEN+TACE: 261, SOR+TACE: 337) were included in the meta-analysis. A higher rate of odds ratio (OR) for the objective response rate (ORR) [OR: 3.63; 95% confidence intervals (95% CI): 1.89-6.95; I squared statistic (I2) = 57%, P < 0.001] and disease control rate (DCR) (OR: 3.78; 95% CI: 2.00-7.16; I2 = 52%, P = 0.0001) were observed in the LEN+SOR group compared with the SOR+TACE group. The LEN+TACE group also had significant longer OS [hazard ratio (HR): 0.67; 95% CI: 0.52-0.85; I2 = 1%, P = 0.001], PFS (HR: 0.49; 95% CI: 0.38-0.62; I2 = 0%, P? 0.001) and TTP (HR: 0.62; 95% CI: 0.45-0.84; I2 = 0%, P = 0.002) compared with the SOR+TACE group. The incidence of hypertension (OR: 3.05; 95% CI: 1.45-6.39; P = 0.003) and proteinuria (OR: 5.25; 95% CI: 1.73-15.89; P = 0.003) were significantly higher in the LEN+TACE group than SOR+TACE group, while LEN+TACE group exhibited a lower rate of hand-foot-skin reaction (HFSR) (OR: 0.51; 95% CI: 0.27-0.95; P = 0.03) compared with the SOR+TACE group.ConclusionThe combination therapy of LEN+TACE showed significant superiority compared with SOR+TACE in terms of its efficacy for patients with uHCC. SOR+TACE should be recommended as a replacement therapy when serious AEs occur during the administration of LEN+TACE as the combination therapy.
