relenvatinib in the tatment of recurrence of hepatocellular carcinoma after liver transplantation

Conditions: Hepatocellular Carcinoma; Liver Transplantation

Summary: the aim of this study is to evaluate the efficacy and safety of lenvatinib in the treatment of recurrence of hepatocellular carcinoma after liver transplantation.

the research is an open, one-arm, single-center study. 40 patients with recurrence of hepatocellular carcinoma after liver transplantation are included according to the criteria of admission. the enrolled patients are treated with lenvatinib (dose: body weight \< 60 kg: 8 mg/day, body weight ≥ 60 kg 12 mg/day). the baseline data of patients are collected before allocation. serum and imaging examination are checked regularly every month to monitor the recurrence of hepatocellular carcinoma and the side effects of lenvatinib. the efficacy and safety of lenvatinib in the treatment of recurrence of hepatocellular carcinoma are observed, and the clinicopathological factors affecting the efficacy of lenvatinib are analyzed. when side effects of lenvatinib occur, the dosage can be reduced according to the patients' condition until discontinuation. when tumor advances, a multidisciplinary team will draw up specific treatment plans according to the patients' condition.
