Cardiotoxicity in Locally Advanced Lung Cancer Patients Treated With Chemoradiation Therapy

Patients will be treated with definitive concurrent chemoradiation with curative intent as determined by their medical and radiation oncologists. We will consider timing of initiation and discontinuation, type, and cumulative dose of platinum based chemotherapy. We will also consider dose, duration, and type of immunotherapy. Radiation therapy will be delivered via proton or proton therapy. Our primary radiation therapy dose-volume exposures are whole heart volumetric dose. As secondary exposures, we will comprehensively define radiation therapy dose parameters to the right ventricle, entire left ventricle, left ventricle segments, coronary arteries, and mean heart dose.
