Radiation Treatments

Stereotactic Body Radiotherapy (SBRT)

Martha Jefferson Hospital offers Stereotactic Body Radiotherapy, a state-of-the-art form of radiotherapy similar to stereotactic radiosurgery, for treatment of selective non-cranial tumors with stereotactic precision. A high dose of ablative radiation is delivered in 1 to 5 sessions to tumors in the lung, spine or liver. For mobile cancers, such as lung or liver lesions, a 4-D CT is obtained in the planning process in order to adapt the radiation delivery to target motion. During treatment, the patient is immobilized in a special body cast to ensure reproducibility and minimize movement. Image-guided radiotherapy is critical both before and during the SBRT treatment for targeting accuracy. Results of treatment with SBRT are highly encouraging. A number of trials report cure rates comparable to surgery for Stage I non-small cell lung cancer. For patients with liver or spine metastases, SBRT offers a noninvasive targeted therapy with excellent local control rates and minimal side effects.
