A Trial of Integrating SBRT With Targeted Therapy in Stage IV Oncogene-driven NSCLC

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. The investigational intervention in this study is SBRT with proton or photon radiation (explained below). "Investigational" means that the intervention is being studied. SBRT and proton radiation therapy are FDA approved radiation delivery systems. However, using it as a treatment for stage IV NSCLC is still investigational. SBRT is a specialized, technologically advanced type of external beam radiation therapy that pinpoints high doses of radiation directly on the cancer. Because of high precision, these treatments spare healthy tissue and are associated with fewer side effects. SBRT is very different from conventional therapy where radiation is delivered in small doses given daily over the course of several weeks. For SBRT, the total dose of radiation is typically administered in 4-5 daily sessions. SBRT can be delivered with standard, so called photon radiation, or proton beam. Neither of these two types of radiation is generally superior over the other. There are technical differences between these two, and depending on tumor location, size, shape, and other factors, the investigators will decide which type of radiation to use for which treatment. After the screening procedures confirm you are eligible to participate in the research study: \- Each participant will receive stereotactic treatment course (SBRT with protons or photons) to the area of their tumor.
