John Muir Health has the most comprehensive, patient-centric neuro-oncology program in the East Bay. One highly specialized treatment capability available to our patients is stereotactic radiosurgery (SRS)/stereotactic body radio therapy (SBRT). John Muir Health was the first health system in the East Bay to offer this radiation-based treatment, which precisely targets the tumor while restricting to a minimum the dose delivered to nearby healthy tissues. SRS/SBRT provides a pain-free, safe and effective means to treat brain and spinal cancers.
A multi-disciplinary staff, including specialists from the fields of radiation oncology, neurosurgery, medical oncology, radiology, neuropsychology, medical physics, and other health care specialists work together to provide individualized treatment. The entire team, including the referring physician, is updated and consulted throughout the duration of treatment.
Frameless delivery – no need to mount a localization frame to the patient’s skull – can be used, achieving the high precision necessary to safely deliver SRS/SRBT. The micro-multileaf collimator, or “beam shaper,” automatically and precisely shapes the photon beam to match a tumor’s preregistered outline from every angle. The system delivers a continuous, even distribution of the prescribed dose as it rotates slowly around the patient’s head. For patients with primary and metastatic brain and spinal tumors that cannot be resected through traditional surgical interventions, this approach provides an alternative with a success rate that matches or betters results from conventional irradiation but with much less toxicity due to the fact that it targets the tumor and spares critical neurologic tissue.
