The Stereotactic Radiation Therapy (SRT) program is jointly operated by the Division of Neurosurgery at the Vancouver General Hospital and the BC Cancer Agency, under the auspices of the Stereotactic Therapy Operations Working Group. Although all patients are treated at the Vancouver Cancer Centre, the program serves as a resource for patients and their physicians throughout the province of British Columbia.

SRT is a specialized form of radiation treatment that utilizes a precisely focused beam of radiation to treat a small, stereotactically defined, target lesion while minimizing irradiation of adjacent normal structures. Our treatment technique utilizes a modified linear accelerator technology. Depending on the clinical circumstances, either a single large dose of radiation (single fraction SRT AKA radiosurgery) or multiple small doses over a 5 to 6 week period (fractionated SRT) is given. Some clinical examples that may be suitable for this technique include arteriovenous malformations, acoustic neuromas, small meningiomas, small pituitary adenomas and cerebral metastasis.

All patients to be considered for SRT are discussed in the interdisciplinary SRT Disposition Conference involving neurosurgeons, radiation oncologists, neuro-radiologists and medical physicists. It is held on the first and fourth Wednesdays of each month and referrals may be made by contacting Dr. Michael McKenzie, Dr. Roy Ma, or Dr. Brian Toyota or Dr. Andrew Lee. Whenever eligible, patients will be treated in the context of prospective clinical trials through the Radiation Therapy Oncology Group and Children's Cancer Study Group.

The members are: Andrew Lee, Gary Redekop, Roy Ma, Lorraine Geddes, Karen Goddard, Michael McKenzie, Marnie Besser; Brenda Clark, Brian Toyota, Sharon Allman, Christine Alexander, Emily Vollans, Richard Lee & Bob Harrison.
