Advanced Inoperable Non-Small Cell Lung Cancer Study

This is a phase III trial to compare the usual treatment for Locally Advanced Non-Small Cell Lung Cancer to the use of stereotactic body radiation therapy (SBRT) in addition to the usual treatment. SBRT is already commonly used in lung cancer treatment, but it has not routinely been added to the usual combination of radiation, chemotherapy, and immune therapy that doctors normally use. This study will help the study doctors find out if this different approach is better, the same, or worse than the usual approach.
