Abstract The effect of radiotherapy on anti-tumor immunity is bidirectional, immunotherapy, especially the combination of immune checkpoint inhibitors (ICIs) and radiotherapy, can produce synergistic effects on anti-tumor immunity. Compared with conventional radiotherapy, stereotactic ablative body radiotherapy (SABR) can achieve high-precision and high-dose irradiation on target lesions, and has stronger anti-tumor immune activation effect. At the same time, due to the steep dose gradient, SABR can better protect the surrounding normal tissues, which is an effective means for the rapid control of local lesions in advanced non-small cell lung cancer (NSCLC). ICIs are an important component of standard treatment for advanced NSCLC. There is growing evidence that SABR in combination with ICIs can benefit patients with advanced NSCLC. This article reviews the biological basis and clinical research progress on the combination of these two therapies, aiming to provide reference for the domestic counterparts to better use this new treatment model.
