Efficacy and Safety of Super-hyperfractionation Pulse Radiotherapy Combined With ICIs for Advanced NSCLC

Recruiting now · Not applicable

Conditions studied: Lung Cancer, Immune Checkpoint Inhibitor, Radiotherapy

In brief

Investigators intend to combine low-dose hypersensitivity with high-dose immunopotentiation effect, and use super-hyperfractionation pulse radiotherapy, which is expected to achieve the effect of in situ vaccine that can enhance tumor killing, protect normal tissues, reduce immune cell damage and enhance tumor immunogenicity at the same time, and play a stronger immunopotentiation effect in combined immunotherapy. Thereby inducing a stronger abscopal effect of radiotherapy.
