Adjuvant Immune Checkpoint Inhibitors in Postoperative Hepatocellular Carcinoma

Hepatic resection is the best treatment for patients with early stage hepatocellular carcinoma (HCC) or selected intermediate or advanced disease. However, the postoperative 5-years recurrent rate is up to 70%, for whom recurrence is a major cause of death. In recent years, several immune checkpoint inhibitors have been approved in advanced HCC by official guidelines. At the same time, four randomizead controlled trials about adjvuant immune checkpoint inhibitors for postoperative HCC are ongoing. However, no study about the safety and efficacy of adjuvant immune checkpoint inhibitors for such patients in clinical practice was reported. Therefore, the investigators plan to investigate the safety and efficacy of adjuvant immune checkpoint inhibitors for patients with high-risk factor of HCC recurrence after curative hepatectomy in a prospective cohort study.
