Background: TARE has been the preferred choice of locoregional therapy to advanced HCC in recent years. We attempted to identify factors contributing to the success of TARE in this retrospective review. Methods: HCC patients who received at least one TARE between 1/1/2015 and 8/30/22 at Ohio State University were included in this study. The patient's baseline characteristics at diagnosis (BLC) were extracted by chart review with post-procedural complications and survival outcomes. Descriptive statistics and log-rank test for survival outcomes were conducted using JMP Pro 16 (SAS Institute Inc., Cary, NC). Results: Our cohort had 144 patients with median age of diagnosis (dx) of 65 years, 81 % Caucasians, 81% males, 5% and 51% with hepatitis B and C, respectively; 24% and 21% ascites (As) and hepatic encephalopathy (HE) at dx, respectively; 72% (n=125) had just one procedure (24 had two planned procedures which were considered as 1), 12% (17) and 1% (2) had second and third procedures for recurrence, respectively. Immune checkpoint inhibitor (ICI) and other systemic therapy (tyrosine kinase inhibitor (TKI) or ramucirumab (Ram)) were given to 27% (5 before and 34 after TARE) and 24% (5 before and 30 after TARE), respectively. Other HCC-related BLC includes the number of lesions 1 vs 2-3 vs multiple = 45% vs 33% vs 22%; single lobe vs two lobes = 66 vs 33%; portal vein tumor thrombosis (PVTT) = in main portal vein vs. non-main veins (left or right or lower level) vs no PVTT = 14% vs 10% vs 76%. Median overall survival (OS) and time to recurrence after the first TARE (TTR) were 11 and 4 months (m), respectively. The only BLC that significantly influenced TTR was As (3 vs 4 m, p=0.008). Factors impacting OS were discussed in the table. Follow-up imaging (median = 3m) was available for response evaluation in 107/144 (indeterminate response (IR) reported in 25), and the response noted was reflective of OS (objective response vs. disease progression vs indeterminate, 22 vs 6 vs 8.5 m, p<0.001). Conclusions: Careful patient selection based on BLC and the use of ICI (before or after) could improve the outcomes in HCC patients treated with TRAE. Larger prospective studies are needed to validate the study.
