Envafolimab combined with Lenvatinib will be started on the day of TACE, and the subsequent TACE will be performed on demand. Patients will receive the treatment continuously until disease progression or intolerance. Tumor imaging evaluation will be performed according to RECIST V1.1 criteria every 6 weeks. Safety will be assessed with CTCAE 5.0. Adverse events throughout and within 30 days of the end of the study will be recorded (severe adverse events or adverse events associated with Envafolimab will be recorded within 90 days after the end of treatment).Treatment will last for 2 years or until disease progression, withdrawal of informed consent, loss of visit, or death.
