Primary endpoint: Recurrence-free survival time (RFS). Secondary endpoints: safety (incidence of adverse events); time to recurrence (TTR); time to local recurrence (TTLR); 12-month recurrence-free survival rate; overall survival (OS); 12 months and 24 Month overall survival rate.~Treatment plan: Patients undergo radiofrequency ablation, 3-5 days after radiofrequency ablation, lenvatinib 12 mg (body weight ≥ 60 kg) or 8 mg (body weight <60 kg) orally, once a day; toripalimab is a fixed dose of 240 mg, once every 3 weeks, intravenous infusion on the first day of each cycle, the infusion time is no less than 60 minutes.Combination therapy until tumor recurrence, disease progression, death or intolerable toxicity occurs.
This study is a multi-center, prospective, single-arm, open-design phase II clinical study, mainly to explore the clinical effectiveness and safety of radiofrequency ablation combined with anti-PD-1 antibody toripalimab and lenvatinib in patients with short-term recurrence of hepatocellular carcinoma.
