Research progress on combined treatment of radiotherapy and anti-CTLA-4 antibody / 中华放射肿瘤学杂志

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.
