Introduction to PRaG Therapy

PRaG therapy is an innovative cancer treatment regimen that based on radiotherapy, PD-1/PD-L1 inhibitors, and granulocyte-macrophage colony-stimulating factor (GM-CSF) to enhance the body’s immune response against tumors. This approach aims to modulate the tumor microenvironment, making it more responsive to immunotherapy. Radiotherapy utilizes high-dose radiation to target and kill cancer cells, while also inducing immunogenic…
