Transarterial Radioembolization for Unresectable Hepatocellular Carcinoma: Real-Life Efficacy and Safety Analysis of Korean Patients.

ABSTRACT: Transarterial radioembolization (TARE) has become widely used in the treatment of HCC, one of the most common causes of cancer mortality worldwide. Here we investigated the long-term clinical outcomes of patients with hepatocellular carcinoma (HCC) treated with TARE in a multi-medical center in Korea. A total of 149 patients treated with TARE from 2008-2014 were recruited. The pre-treatment HCC stage was classified according to the BCLC stage, of which C and D were defined as advanced HCC. Advanced HCC stage and Child-Turcotte-Pugh (CTP) score A were identified in 62 (42%) and 134 (90%) patients, respectively. Portal vein thrombosis (PVT) was identified in 58 patients (38.9%). The median time to progression (TTP) was 14 months, and the median overall survival (OS) and progression-free survival (PFS) were 18.6 and 8.9 months, respectively. The overall tumor response was 47%, and the disease control rate was 78%. OS and PFS differed significantly according to the presence of liver cirrhosis, extrahepatic metastasis, tumor response and curative treatment after TARE (all, p < 0.05). Multiple tumors and major PVT were other independent factors related to OS, while the des-gamma carboxy protein level predicted PFS (all, p < 0.05). Tumor size was an independent predictor of tumor response. TTP, OS and PFS all differed among BCLC stages. The serious adverse effect after TARE was clinically not significant. Therefore, TARE is safe and effective in treating early to advanced HCCs.

Project description:IntroductionGiven the relatively short life expectancy of patients with hepatocellular carcinoma (HCC), quality of life (QOL) plays a significant role in treatment selection. This analysis aimed to compare time to deterioration (TTD) in QOL with transarterial radioembolization (TARE) and atezolizumab-bevacizumab, as well as sorafenib, in advanced and unresectable HCC.MethodsPatient-level data from SARAH (TARE using SIR-Spheres® Y-90 resin microspheres [SIR-Spheres] versus sorafenib) and aggregate data from IMbrave150 (atezolizumab-bevacizumab versus sorafenib) randomized controlled trials were used to conduct an anchored matching-adjusted indirect comparison (MAIC). Patients with a Child-Pugh score B in SARAH were excluded to align with exclusion criteria in IMbrave150. To identify potential effect modifiers for adjustment, the literature was searched and multivariate Cox proportional hazards models were implemented using SARAH data. Patients from SARAH were then weighted to balance with baseline characteristics from IMbrave150. Median TTD in QOL and hazard ratios (HRs) were calculated.ResultsFour potential effect modifiers were identified and used for adjustment: cause of disease (viral/non-viral), macrovascular invasion, Eastern Cooperative Oncology Group performance score, and alpha-fetoprotein level. The MAIC included 217 patients from SARAH (TARE = 94; sorafenib = 123). Median TTD in QOL was 11.23 and 8.64 months for atezolizumab-bevacizumab and TARE, respectively (HR = 1.06; 95% confidence interval [CI] 0.75-1.50; p = 0.725). A sensitivity analysis was conducted adjusting for cause of disease defined as hepatitis B/hepatitis C/non-viral: median TTD in QOL was higher for TARE compared with atezolizumab-bevacizumab (19.88 vs 11.23 months; HR = 0.66; 95% CI 0.36-1.19; p = 0.163). Sorafenib resulted in the shortest TTD in QOL, with statistically significant differences in both base case and sensitivity analyses.ConclusionTARE using SIR-Spheres may achieve similar TTD in QOL compared with atezolizumab-bevacizumab, as the analyses found no statistically significant differences between these two interventions. Both TARE using SIR-Spheres and atezolizumab-bevacizumab seem to be more efficacious than sorafenib in maintaining QOL.

Project description:PurposeThis study aimed to assess the efficacy and safety of a triple therapy that comprises transarterial chemoembolization (TACE), antiangiogenic-targeted therapy, and programmed death-1 (PD-1) inhibitors in a real-world cohort of patients with unresectable hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT).MethodsConsecutive patients treated with TACE combined with antiangiogenic therapy and PD-1 inhibitors at the Eastern Hepatobiliary Surgery Hospital between June 2019 and May 2021 were enrolled. The baseline characteristics and treatment course of the patients were recorded. The tumor response was evaluated based on the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and HCC-specific modified RECIST (mRECIST). The overall survival (OS) and progression-free survival (PFS) of the patients were analyzed using the Kaplan-Meier method. Adverse events (AEs) were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.ResultsAs of the data cutoff on 30 August 2021, the median follow-up time was 10.0 (3.9-28.4) months. A total of 39 eligible patients were included. The objective response rate (ORR) and the disease control rate (DCR) were 35.9% and 74.4% according to the RECIST 1.1, and 48.7% and 84.6% according to mRECIST criteria, respectively. The median OS and PFS were 14.0 and 9.2 months, respectively. Moreover, 34 (87.2%) patients experienced at least one treatment-related AE and 8 (20.5%) patients experienced grade 3/4 treatment-related AEs. The most common treatment- and laboratory-related AEs were hypertension (46.2%) and decreased albumin (53.8%), respectively. No treatment-related mortality occurred during the study period.ConclusionsTACE combined with antiangiogenic-targeted therapy and immune checkpoint inhibitors may have promising anticancer activity in unresectable HCC patients with PVTT. AEs were manageable, with no unexpected overlapping toxicities.
