Concurrent transarterial radioembolization and combination atezolizumab/bevacizumab treatment of infiltrative hepatocellular carcinoma with portal vein tumor thrombosis: a case report.

ABSTRACT: Treatment options for advanced hepatocellular carcinoma (HCC) have been rapidly evolving. Herein, we describe a patient with advanced HCC and portal vein tumor thrombosis (PVTT) who responded decisively to a multidisciplinary approach. The patient had an ill-defined infiltrative HCC (diffuse subtype), with several intrahepatic metastasis and tumor invasion of left portal vein. Concurrent use of transarterial radioembolization (TARE) and systemic therapeutics (atezolizumab + bevacizumab) ultimately proved successful. There was marked reduction in tumor volume after TARE and an additional three cycles of atezolizumab plus bevacizumab. This concurrent treatment was well tolerated, without adverse events during immunotherapy. The impressive results achieved suggest that concurrent TARE and combination atezolizumab/bevacizumab is a promising treatment approach for advanced HCC with PVTT.

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.
