Stereotactic External-Beam radiation Therapy, sometimes called SBRT is now being used to treat Small Cell Lung Cancer, and Sarcomas that have metastasized to the lungs. The high doses used in thoracic SBRT can sometimes cause adverse effects ranging from mild rib fatigue and transient esophagitis , to fatal events such as pneumonitis or hemorrhage.
Stereotactic radiosurgery provides an efficient, safe, and minimal invasive treatment alternative [15] for patients diagnosed with malignant, benign and functional indications in the brain and spine, including but not limited to both primary and secondary tumors. [16] Stereotactic radiosurgery is a well-described management option for most ...
During treatment, the image guidance system captures 3D images, tracks the movement of tumors, and guides the robotic arm to accurately aim the treatment beam at the moving tumor. [2] The system is designed for stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT).
Each individual beam is of relatively low intensity, so the radiation has little effect on intervening brain tissue and is concentrated only at the tumor itself. Gamma Knife radiosurgery has proven effective for patients with benign or malignant brain tumors up to 4 cm (1.6 in) in size, vascular malformations such as an arteriovenous ...

Stereotactic radiosurgery (SRS) is when doctors use a single or several stereotactic radiation treatments of the brain or spine. Stereotactic body radiation therapy (SBRT) refers to one or several stereotactic radiation treatments with the body, such as the lungs.
Radiation therapy is commonly used to treat known tumor occurrence in the brain, either with highly precise stereotactic radiation or therapeutic cranial irradiation. By contrast, PCI is intended as preemptive treatment in patients with no known current intracranial tumor, but with high likelihood for harboring occult microscopic disease and ...
WBRT may be administered in combination with stereotactic radiosurgery (SRS), surgery, or systemic therapies. [1] While these can improve survival for some patients with single brain metastasis, a 2021 systematic review of the literature found inconsistent results for overall survival. [1]
