Predictive Biomarkers for Pneumonitis After Chemoradiotherapy and Immunotherapy in Patients With Non-small Cell Lung Cancer

This study looks at the side effects of chemotherapy and radiation (chemoradiation) followed by immunotherapy in patients with non-small cell lung cancer, with a particular focus on lung inflammation (pneumonitis). By collecting blood, stool and saliva samples, and data from lung function tests, researchers may be able to create a database of information about treatment and side effects in patients with non-small cell lung cancer who are receiving chemoradiation followed by immunotherapy. The information gained from this study may also help researchers find signs of problems with lung function earlier rather than later, since lung function is checked more often than routine care. This may improve how quickly these issues can be treated, and future patients may benefit from what is learned.
