Brief Summary
This is a prospective, randomized, controlled, exploratory Phase II clinical study. Approximately 60 eligible patients with hepatocellular carcinoma and portal vein tumor thrombus who have received three cycles of target-immunotherapy induction and have non-progressive disease will be enrolled. All patients must be considered unresectable or unable to tolerate surgical resection by MDT review and must provide written informed consent. Participants will be randomized 2:1. Forty patients will undergo open or percutaneous IRE followed by continuation of the original target-immunotherapy regimen; twenty patients will continue the original treatment regimen alone. OS, PFS, tumor response, QoL, safety, and postoperative outcomes will be observed.
