Brief Summary:
Current dose escalation regimens with and without chemotherapy have failed to achieve improved local control and overall survival over standard of care therapy to date. Difficulties with dose escalation have been largely due to dose limiting toxicities of surrounding normal organs, in particular to the normal lung parenchyma, and esophagus. Real time, online adaptive planning using magnetic resonance imaging (MRI) could achieve significant volume reduction of primary lung disease over the course of therapy, thereby reducing dose to normal structures, and providing a mechanism in which to dose escalate safely, and more effectively with accurate target delineation.
The investigators hypothesize that MRI based adaptive planning will provide a novel method to dose escalate safely with acceptable organ at risk doses. In addition, further improvements in radiotherapy targeting accuracy, normal tissue avoidance, and conformality of target-tissue coverage will be achieved through the use of 4D real-time tracking which is derived by deformably registering daily MR and planning MR (MRsim) and Computed Tomography Simulator (CTsim) with advanced non-rigid image-registration tools.
Detailed Description:
This study is a single-arm phase II study of adaptive radiotherapy using ViewRay MRI based imaging in locally Advanced non-small cell lung cancer patients. Randomization is not applicable.
