Local Consolidation After Sintilimab Plus Lenvatinib for Metastatic Liver Cancer

This study evaluates whether comprehensive local consolidative therapy added to continued sintilimab plus lenvatinib improves survival compared with continued sintilimab plus lenvatinib alone in patients with oligo-extrahepatic metastatic hepatocellular carcinoma. All enrolled participants receive induction treatment with sintilimab plus lenvatinib for 4 cycles. Participants who achieve disease control and are confirmed by central multidisciplinary review to be feasible for complete consolidation are randomized in a 1:1 ratio to receive either comprehensive local consolidative therapy followed by continued systemic therapy or continued systemic therapy alone. The primary outcome is overall survival.
