Official title
Radical-Dose Image Guided Radiation Therapy in Treating Patients With Metastatic Non-small Cell Lung Cancer Undergoing Immunotherapy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase II trial studies how well radical-dose image guided radiation therapy works in treating patients with non-small cell lung cancer that has spread to other places in the body who are undergoing immunotherapy. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving radical-dose image guided radiation therapy to patients with non-small cell lung cancer may help to improve response to immunotherapy anti-cancer treatment.
