Abstract: Objective response rate (ORR), overall survival (OS), progression-free survival (PFS) and toxicity were recorded. Results: Thirty-four patients were retrospectively enrolled between January 2016 and September 2021. Most patients received concurrent targeted therapy (70.6%) and/or post-RT (79.4%). The in-field ORR and disease control rates were 79.4% and 97.1%, respectively. The OS rates were 77.6% at 1 year and 36.3% at 2 years (median OS, 15.8 months). The median PFS and median in-field PFS were 4.2 months and not reached, respectively. The PFS and in-field PFS rates were 24.6% and 79.2% at 1 year, 19.7% and 72.0% at 2 years, respectively. An alpha-fetoprotein level > 1000 ng/mL was a significant prognostic factor for worse OS (HR, 5.674; 95% CI, 1.588– 20.276; p=0.008); in-field complete/partial response was a significant prognostic factor for better OS (HR, 0.116; 95% CI, 0.027– 0.499; p=0.004). The most common site of first failure was the lungs (13/34 patients, 38.2%), followed by the liver (7/34 patients, 20.6%). No patients developed radiation-induced liver disease or pulmonary embolism during follow-up. Conclusion: Combining RT and systemic therapy was safe and effective in treating patients with HCC with HVTT and IVCTT. [ABSTRACT FROM AUTHOR]
