肝细胞癌的免疫治疗进展
Advances in immunotherapy for hepatocellular carcinoma
原发性肝癌(PLC)是全球发病率和病死率均较高的常见恶性肿瘤。肝细胞癌(HCC)是PLC的主要类型,在亚洲多由乙型肝炎病毒感染引起。尽管近年来在靶向治疗和局部治疗方面取得了进展,但其5年生存率依然较低,提示现有治疗手段疗效有限。免疫治疗的出现,特别是免疫检查点抑制剂(ICI),为PLC患者带来了新的希望。然而,由于肝脏独特的免疫微环境,免疫治疗在HCC中的疗效仍面临严峻挑战。本文综述了近年来肝癌免疫治疗的研究进展,重点讨论ICI、联合治疗、新兴疗法以及未来的发展方向。
Primary liver cancer (PLC) is a prevalent malignancy with high incidence and mortality rates globally. Hepatocellular carcinoma (HCC), primarily resulting from hepatitis B virus infections in Asia, constitutes most PLC cases. Despite advancements in targeted therapies and localized treatments, the 5-year survival rate remains low, indicating limited efficacy of current approaches. The advent of immunotherapy, particularly immune checkpoint inhibitors (ICIs), has brought new hope for patients with PLC. However, the liver's unique immune microenvironment presents significant challenges to the effectiveness of immunotherapy in HCC. This article reviews recent research developments in liver cancer immunotherapy, focusing on ICIs, combination therapies, emerging treatments, and prospective future directions.
