Stereotactic Radiation Offers New Hope for Many Cancer Patients

March 10, 2017

About 60% of all cancer patients will be treated with radiation therapy at some point during their care. What that therapy looks like has been undergoing a rapid transformation in recent years. Thanks to technological advances and research in radiation oncology, stereotactic radiation has taken its place as an advanced tool in today’s cancer fighting arsenal. It has proven  its ability to eradicate certain tumors with surgical precision, opening up new and effective treatments for patients who previously had little or no options.

So what is stereotactic radiation and how is it different from traditional radiation therapy?

  • Stereotactic treatments deliver high doses of localized radiation with pinpoint accuracy to eradicate tumors.
  • Traditional radiation therapy is given in small doses over several weeks. Stereotactic approaches can often be delivered over a few days.
  • These procedures minimize the effect on healthy tissue resulting in limited side effects.

There are different types of stereotactic applications depending on the part of the body being treated. Stereotactic Radiosurgery (SRS) is used to treat cancers in the brain, either in conjunction with or instead of surgery. Compass radiologists routinely perform SRS at our Vancouver and Rose Quarter centers or at the Gamma Knife Center of Oregon depending on the circumstances.

Stereotactic Body Radiation Therapy (SBRT) uses the same principle of delivering high doses of radiation with pinpoint accuracy as SRS does, only the location of the tumor is different. Some commonly treated sites include primary and secondary tumors in the lung, liver, pancreas and adrenal glands. In addition, because SBRT is quick and applicable to multiple areas, it may offer a reasonable chance of remission for patients with low volume metastatic disease or those with recurrent disease who develop metastatic sites.

Without a doubt, SBRT is a rapidly evolving technology and we will likely see it applied to more areas. As with all rapidly evolving technologies, widespread information about their availability and applications sometimes lags behind. We encourage patients to ask their doctors if they may benefit from stereotactic radiation therapy.

It is important to note, when to apply stereotactic approaches in radiation oncology involves complex treatment decisions. As early adopters of SRS and SBRT, Compass radiation oncologists are on the leading edge of developing and applying stereotactic radiation as part of our comprehensive approach to evidence based cancer care. While these procedures are not appropriate for every patient, they are offering new hope for an increasing number of patients who previously had very few options.
