Increased Magnetic Resonance Imaging Surveillance to Reduce the Rate of Symptomatic Brain Metastasis in Patients Treated with Radiation Therapy for Stage III, Locally Advanced Non-Squamous Non-Small Cell Lung Cancer

Trial Status: active

This phase II trial tests how well increased magnetic resonance imaging (MRI) surveillance works in reducing the rate of symptomatic cancer that has spread to the brain (brain metastasis) in patients treated with radiation therapy for stage III non-squamous non-small cell lung cancer (NSCLC) that has spread to nearby tissue or lymph nodes (locally advanced). An MRI allows doctors to see and take pictures of the brain. MRI is a form of imaging that uses radiofrequency waves and a strong magnetic field rather than x-rays to provide detailed pictures of internal organs and tissues. The technique is valuable for the diagnosis of many pathologic conditions, including metastatic disease. During the MRI, patients may receive an injection of a chemical called gadolinium. This is called a contrast agent and helps to see parts of the brain better. Researchers want to learn if increasing surveillance of the brain using MRI after radiation therapy will allow them to find brain metastasis before it causes symptoms.
