Phase 3

Conditions
Hepatocellular Carcinoma
Interventions
Registration Number
NCT06089369
Lead Sponsor
Tongji Hospital
Brief Summary

To compare the impact on recurrence risk of adjuvant Sintilimab (a recombinant fully human anti-PD-1 monoclonal antibody) for patients with hepatocellular carcinoma and microvascular invasion (MVI) after hepatectomy.

Detailed Description

This study is a prospective, multicenter, open-label, randomized controlled clinical trial, aiming to recruit 360 patients with MVI-positive HCC who have undergone surgical resection. The patients will be randomly divided into three groups: the first group will receive six months of adjuvant therapy with Sintilimab (200 mg every three weeks for a total of 9 cycles), the second group will receive one year of adjuvant therapy with Sintilimab (200 mg every three weeks for a total of 18 cycles), and the Active surveillance group will be closely followed postoperatively. A maximum of one postoperative adjuvant TACE is permitted.
