Stereotactic Radiation Therapy and Radiosurgery are special types of radiation treatments available at Thompson Cancer Survival Center. For patients with vertebral metastasis, which means their cancer has spread to the spine, Image-Guided Stereotactic Radiotherapy and Radiosurgery often allow physicians to continue radiation therapy even after patients have reached their tolerance with traditional radiation treatments.
To continue radiation treatment, the radiation oncology team combines Intensity Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT). IMRT allows the radiation to be shaped around the spinal cord, while IGRT allows the spinal cord and the tumor to be precisely positioned before the treatment so that the radiation hits the tumor - not the spinal cord.
Thompson's IGRT and radiotherapy treatment uses 3-D imaging to position the patient for treatments. CT images taken of the patient immediately before treatment are used to create a 3-D model of the patient. This method allows physicians to align the patient for treatment using the internal anatomy instead of implanted metal tracking markers or head frames. The entire treatment procedure lasts less than 30 minutes.
