Comparison of radiofrequency ablation combined with sorafenib or sorafenib alone in patients with ECOG performance score 1: identifying optimal candidates.

ABSTRACT: Background:Sorafenib has been recommended as the first-line treatment and shown to prolong the median overall survival (OS) of patients with advanced unresectable hepatocellular carcinoma (HCC). Recently, a growing number of earlier studies showed the application of radiofrequency ablation (RFA) plus sorafenib in patients diagnosed at the advanced-stage HCC. This study aimed to compare the outcomes of RFA plus sorafenib versus sorafenib alone and identify prognostic factors related to OS for BCLC stage C patients with PS 1 but without vascular invasion or extrahepatic spread. Methods:A total of 276 consecutive patients in BCLC stage C with PS 1 but without vascular invasion or extrahepatic spread were enrolled in this retrospective study. Survival analyses were performed using the Kaplan-Meier analysis, and the log-rank test examined the statistical differences between the transarterial chemoembolization (TACE) and sorafenib groups. Univariate and multivariate Cox regression analyses were performed to investigate the prognostic factors for OS. Results:Based on the Kaplan-Meier curves, patients treated with RFA plus sorafenib showed better OS than those undergoing sorafenib, with respective OS at 1, 3 and 5 years (84.0%, 43.1%, 22.8% vs. 55.6%, 29.6%, 4.8%, Log-rank P<0.001). The univariate analysis and multivariate analysis showed that tumor size, tumor number, treatment method, albumin, bilirubin, and the Child-Pugh score were associated with OS. According to the subgroups analyses based on the tumor size and tumor number, there were significant differences in OS among overall subsets except in patients with tumor number ?4 between RFA plus sorafenib and sorafenib therapy. Conclusions:RFA plus sorafenib provided better prognostic performance than sorafenib, which should be suggested as an alternative treatment modality compared with sorafenib for BCLC stage C patients with PS 1 but without vascular invasion or extrahepatic spread.

Project description:BackgroundSorafenib has been recommended as the first-line treatment and shown to prolong median overall survival (OS) of patients with advanced unresectable hepatocellular carcinoma (HCC). Recently, a growing amount of research has supported the application of transarterial chemoembolization (TACE) in patients with advanced-stage HCC. The aim of this study was to compare the outcomes of TACE and sorafenib and identify the prognostic factors related to OS for Barcelona Clinic Liver Cancer (BCLC) stage C patients with PS 1 but without vascular invasion or extrahepatic spread.MethodsA total of 323 consecutive patients in BCLC stage C with PS 1 but without vascular invasion or extrahepatic spread were enrolled in this retrospective study. Survival analyses were performed using the Kaplan-Meier analysis, and the statistical differences between the TACE and sorafenib groups were examined by the log-rank test. Univariate and multivariate Cox regression analyses were performed to investigate the prognostic factors for OS.ResultsBased on the Kaplan-Meier curves, patients treated with TACE showed a better OS than those undergoing sorafenib, with respective OS at 1, 3, and 5 years (67.7%, 41.5%, 23.2% vs. 55.6%, 29.6%, 4.8%; log-rank P=0.002). The univariate analysis indicated that tumor size, tumor number, and treatment method, along with platelet (PLT), white blood cell (WBC), and α-fetoprotein (AFP) count, were associated with OS. The multivariate analysis demonstrated that tumor size, tumor number, and treatment method were significant prognostic factors for OS. According to the subgroups analyses based on the tumor size and tumor number, there were significant differences in OS among overall subsets between TACE and sorafenib therapy.ConclusionsTACE provided better prognostic performance than sorafenib and should be suggested as an alternative treatment modality to sorafenib for BCLC stage C patients with PS 1 but without vascular invasion or extrahepatic spread.

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:ObjectivesWe aimed to compare the therapeutic outcomes of radiofrequency ablation (RFA) and microwave ablation (MWA) as first-line therapies in patients with small single perivascular hepatocellular carcinoma (HCC).MethodsA total of 144 eligible patients with small (≤ 3 cm) single perivascular (proximity to hepatic and portal veins) HCC who underwent RFA (N = 70) or MWA (N = 74) as first-line treatment were included. The overall survival (OS), disease-free survival (DFS), and local tumor progression (LTP) rates between the two ablation modalities were compared. The inverse probability of treatment weighting (IPTW) method was used to reduce selection bias. Subgroup analysis was performed according to the type of hepatic vessels.ResultsAfter a median follow-up time of 38.2 months, there were no significant differences in OS (5-year OS: RFA 77.7% vs. MWA 74.6%; p = 0.600) and DFS (5-year DFS: RFA 24.7% vs. MWA 40.4%; p = 0.570). However, a significantly higher LTP rate was observed in the RFA group than the MWA group (5-year LTP: RFA 24.3% vs. MWA 8.4%; p = 0.030). IPTW-adjusted analyses revealed similar results. The treatment modality (RFA vs. MWA: HR 7.861, 95% CI 1.642-37.635, p = 0.010) was an independent prognostic factor for LTP. We observed a significant interaction effect of ablation modality and type of peritumoral vessel on LTP (p = 0.034). For patients with periportal HCC, the LTP rate was significantly higher in the RFA group than in the MWA group (p = 0.045). However, this difference was not observed in patients with perivenous HCC (p = 0.116).ConclusionsIn patients with a small single periportal HCC, MWA exhibited better tumor control than RFA.Key points• Microwave ablation exhibited better local tumor control than radiofrequency ablation for small single periportal hepatocellular carcinoma. • There was a significant interaction between the treatment effect of ablation modality and type of peritumoral vessel on local tumor progression. • The type of peritumoral vessel is vital in choosing ablation modalities for hepatocellular carcinoma.
