Advances in Stereotactic Body Radiation Therapy for Lung Cancer.

Stereotactic body radiation therapy (SBRT) delivers curative-intent radiation to patients with early-stage non-small cell lung cancer and inoperable thoracic lesions. With improved techniques in tumor delineation, motion management, and delivery of radiation treatments, the therapeutic window within the thorax is able to be maximized. Ongoing technological advances enable highly targeted ablative radiation therapy while sparing adjacent sensitive organs at risk. Further applications of SBRT with combinatorial immunotherapy, the usage of particle therapy, and for patients with more advanced stages of lung cancer and other histologies mark exciting possibilities for the role of SBRT within the thorax.
