Dose-escalated Adaptive Radiotherapy of Thoracic Disease for Small Cell Lung Cancer (DARTS): A Prospective Phase II Trial Evaluating Local Control of Adaptive Dose-escalated Radiotherapy

IIT-0015

The purpose of this study is to find out what effects of using adaptive radiotherapy to deliver chest radiation has on the ability to control lung cancer and side effects.
