Treatment Comparison: SBRT v. Conventional Radiation Therapy

Our center uses stereotactic body radiation therapy (SBRT) to treat a variety of tumors in practically any area of the body. But when compared to conventional radiation therapy do you know the most important differences? Here are some key distinctions between the two treatments:

  • Number of radiation beams – SBRT delivers more than 100 radiation beams from many angles compared to the 2-7 beams administered with conventional radiation therapy. The higher number of beams used with SBRT allows doctors to administer high doses of radiation to a very specific target area with less risk of harming surrounding healthy tissue.
  • Treatment length – Treatment with SBRT can typically be completed within a week, whereas conventional radiation therapy can take 6-7 weeks.
  • Accuracy – SBRT can be delivered to a tumor location within 1-5 millimeters of the tissue margin while the accuracy of conventional radiation therapy is around 20-30 millimeters.
  • Radiation dose – Doses of radiation are much higher when administered with SBRT compared to conventional radiation.

While these key differences in treatment are important, there are several factors in determining which treatment is right for your particular diagnosis. Call our center to learn more and discover if you are a candidate for CyberKnife treatment.
