RecruitingProcedureCardiovascular Injury and Cardiac Fitness in Locally Advanced Non-Small Cell Lung Cancer Patients Receiving Model Based Personalized ChemoradiationThis study assesses cardiovascular injury and cardiac fitness in patients with non-small cell lung cancer that has spread to nearby tissue or lymph nodes (locally advanced) receiving model based personalized chemoradiation. The goal of this study is to learn more about the risk of developing heart disease as a result of chemoradiation treatment for lung cancer. Researchers also want to learn if the risk can be reduced by using a patient's individual risk profile to guide cancer treatment and help protect the heart.
