Lung tumors

The modern evolution in radiotherapy is highly dependent on the continuous introduction of novel technologies that facilitate modulation of the tumor and normal tissue differential response. Magnetic resonance-guided radiation therapy (MRgRT) is one of such developments. Lung malignancies are associated with significant motion and/or proximity to organs at risk. MRgRT lends itself well to the management of such tumors and can potentially improve tumor control, survival, and patients’ quality of life. In this chapter, we present the potential benefits and challenges of magnetic resonance imaging in lung cancer, explore the current evidence on MRgRT, which have primarily focused on dosimetric benefits in early and locally advanced stage lung cancer and inform on currently initiated trials assessing its safety and efficacy.
