Status and challenges of neoadjuvant immunotherapy for hepatocellular carcinoma / 中华外科杂志

ABSTRACT

With the development of modern liver surgical techniques and the progress of perioperative management,the survival rate after resection of hepatocellular carcinoma has been greatly improved,but the high recurrence and metastasis rate still limits the long-term survival after surgery. Preoperative neoadjuvant therapy has been confirmed to significantly reduce the postoperative recurrence rate and prolong survival in other types of cancer,but there has been a lack of effective systemic therapy for hepatocellular carcinoma for a long time,so the efficacy and regimen of neoadjuvant therapy for hepatocellular carcinoma are still controversial. PD-1/PD-L1 monoclonal antibody combined with anti-angiogenic targeted drugs has become a first-line regimen in systemic therapy for advanced hepatocellular carcinoma. This regimen has definite efficacy and high safety,bringing hope for neoadjuvant therapy of hepatocellular carcinoma. Recently,three clinical trials of neoadjuvant immunotherapy for hepatocellular carcinoma have been published internationally,which preliminarily suggest the efficacy and safety of neoadjuvant immunotherapy for hepatocellular carcinoma and lay a solid foundation for carrying out larger sample clinical studies in the future.
