Summary

Although sorafenib is the standard treatment for hepatocellular carcinoma with portal vein invasion, the outcome of these patients remains very poor, with a median survival time of 5.5 to 7.2 months. It has been demonstrated that first-line treatment with transarterial chemoembolization plus radiotherapy could provide more favorable survival than sorafenib alone. However, intrahepatic dissemination and distant metastasis remains the major recurrence pattern after treatment in these patients; therefore, searching for new strategies to improve efficacy is necessary. Immunotherapy targeting the PD-1/PD-L1 checkpoints has demonstrated promising activity in advanced HCC. Combining radiotherapy with immune checkpoints showed promising response rates and improved survival in several solid tumor types. The aim of this randomized study was to investigate the efficacy and safety of stereotactic body radiotherapy followed by sintilimab (an anti-PD-1 antibody) compared with stereotactic body radiotherapy alone for hepatocellular carcinoma with portal vein invasion after arterially directed therapy.

Description

A total of 116 HCC patients with portal vein invasion after arterially directed therapy (transarterial chemoembolization or hepatic arterial infusion chemotherapy) will be randomized to two treatment arms using a 1:1 ratio: SBRT + PD-1 arm or SBRT alone arm. Patients in both arms will receive stereotactic body radiotherapy (SBRT) using volumetric arc therapy. The prescribed dose is 30-54 Gy in 3-6 fractions over 1-2 weeks. In the SBRT + PD-1 arm, sintilimab is administered intravenously at 200 mg every 3 weeks for up to 1 year. The first course of sintilimab will be given within 4-6 weeks after completion of SBRT.
