Abstract:
Immune checkpoint blockade can promote the tumor?specific cytotoxic T?lymphocyte ( CTL) response. However, only a small proportion of patients have good response to immune checkpoint blockade. It has been reported that radiotherapy combined with immune checkpoint blockade can promote antigen presentation, which further enhances the tumor?specific CTL response;moreover, the combined therapy achieves better treatment outcomes than radiotherapy alone or immune checkpoint blockade alone. The latest study has shown that radiotherapy combined with dual immune checkpoint blockade has better efficacy than radiotherapy combined with CTLA?4 blockade in patients with melanoma. Therefore, radiotherapy combined with immune checkpoint blockade will become a new approach for treating tumor. This paper reviews the research advances in the combined therapy.
