To the Editor: Based on randomized studies (1, 2), immune checkpoint inhibition (ICI) for advanced non-small cell lung cancer (NSCLC) is a growing treatment modality with established efficacy and safety. Stereotactic radiation therapy (SRT), including radiosurgery and hypofractionated protocols, is a standard treatment for limited intracranial metastatic disease. Furthermore, with technology advances in SRT, more than 10 lesions could be treated simultaneously (3).
