Extracranial Stereotactic Radiation Delivery

Extracranial stereotactic radiation delivery, also known as stereotactic body radiation therapy (SBRT), involves delivering very potent doses of radiation to well-demarcated tumors in the neck, spine, chest, abdomen, and pelvis. Beyond just stereotactic targeting, it represents a formalism of treatment planning and conduct that facilitates the delivery of the most potent dose fractionation schedules ever considered in the field of radiation oncology. In doing so, it uses the most modern technologies to simultaneously hit the target and avoid normal innocent tissues. Clinical results already show that SBRT constitutes a new paradigm in cancer treatment that deserves careful implementation and assessment for the improvement in patient outcomes.
