Traditional
management strategies for patients with spinal tumors have undergone
considerable changes during the last 15years.
Significant improvements in digital imaging, computer processing, and treatment
planning have provided the basis for the application of stereotactic techniques,
now the standard of care for intracranial pathology, to spinal pathology.
In addition, certain of these improvements have also allowed us to progress from
frame-based to frameless systems which now act to accurately assure the delivery
of high doses of radiation to a precisely defined target volume while sparing
injury to adjacent normal tissues.
In this
article we will describe the evolution from yesterday's standards for radiation
therapy to the current state of the art for the treatment of patients with
spinal tumors.
This
presentation will include a discussion of radiation dosing and toxicity, the
overall process of extracranial radiation delivery, and the current state of the
art regarding Cyberknife, Novalis, and tomotherapy.
Additional discussion relating current research protocols and future directions
for the management of benign tumors of the spine will also be presented.
