Lenvatinib Combined with Tislelizumab and TACE Applied As Neoadjuvant Regimen for the Patients of CNLC Stage IB and IIA Hepatocellular Carcinoma with High-risk Recurrence Factors

Summary

This is a monocenter, single-arm, open-label study to evaluate the efficacy and safety of Lenvatinib combined with Tislelizumab and TACE applied as neoadjuvant regimen for the patients of CNLC stage IB and IIA hepatocellular carcinoma with high risk of recurrence Primary outcome: Major pathological response (MPR) Secondary outcomes: pathological complete response (pCR), R0 resection rate, objective response rate (ORR), disease control rate (DCR), treatment-related adverse events (TRAE)
