放疗联合CTLA-4单抗的机制与临床研究进展

放疗是肿瘤治疗三大手段之一,近年来伴随着免疫治疗的飞速发展,放疗联合免疫治疗的理论与实践方式也愈发得到关注。人细胞毒性T细胞抗原4(CTLA-4)抑制剂是免疫治疗的重要药物之一,在黑色素瘤、肺癌等癌种的治疗中都显示出巨大的应用潜力,因而其与放疗联用的机制与方式也成为目前关注的重点。本文梳理了近年来CTLA-4单抗与放疗联用的基础与临床研究实践,为下一步开展相关研究提供参考。

Research progress on combined treatment of radiotherapy and anti-CTLA-4 antibody

Radiotherapy (RT) is one of the three prevailing therapeutics for tumors. With rapid development of immunotherapy (IM), the combination of IM and RT has gainned increasingly widespread attention. Cytotoxic T lymphocyte associated protein-4(CTLA-4) inhibitor is an important checkpoint target in immune activation and regulation, which exerts significant anti-tumor effects in melanoma and non-small cell lung cancer, etc. Accordingly, the combination of RT and anti-CTLA-4 antibody has become a hot spot. This article reviews research progress on pre-clinical and clinical evidences of RT combined with anti-CTLA-4 antibody, which provides evidence for further exploration in this field.
