Summary
This phase II/III trial compares the addition of radiation therapy to the usual treatment (immunotherapy with or without chemotherapy) versus (vs.) usual treatment alone in treating patients with non-small cell lung cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic) whose tumor is also negative for a molecular marker called PD-L1. Stereotactic body radiation therapy (SBRT) is a type of radiation therapy that uses high energy x-rays to kill tumor cells and shrink tumors. This method uses special equipment to position a patient and precisely deliver radiation to tumors with fewer doses over a shorter period and may cause less damage to normal tissue than conventional radiation therapy. Immunotherapy with monoclonal antibodies, such as nivolumab, ipilimumab may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The addition of radiation therapy to usual treatment may stop the cancer from growing and increase the life of patients with advanced non-small cell lung cancer who are PD-L1 negative.
