Intensity-Modulated Radiation Therapy (IMRT)   

Stereotactic Radiosurgery (SRS) and Stereotactic Radiobody Treatment (SBRT)

Stereotactic Radiosurgery (SRS) is not actual surgery – it’s a type of radiation treatment that gives a large dose of radiation to a small tumor area.

The term SRS usually refers to treatment in the brain while and the term Stereotactic Radiobody Therapy (SBRT) refers to the same type of treatment in other parts of the body. These noninvasive treatments use hundreds of highly focused radiation beams to attack tumor cells.

SRS and SBRT can lead to better outcomes and fewer side effects than conventional radiation therapy since the radiation beams are much smaller. Treatment can be delivered in as little as one to five sessions.

SRS and SBRT work by distorting and destroying the DNA of tumor cells, much the same way as other forms of radiation. As a result, these cells lose their ability to reproduce and expire.

SRS and SBRT can deliver precisely targeted beams with remarkable accuracy using fewer high-dose treatments than traditional radiation therapy, which can help preserve healthy tissue and cognitive function in cases of brain tumors.

Who is a Candidate for SRS or SBRT?

This sophisticated technology allows us to target and track specific tumors, including those difficult to reach or considered inoperable. Specific types of SRS include targeted therapy for:

  • Kidney Cancer
  • Liver Cancer
  • Lung Cancer
  • Malignant and Benign Tumors and Lesions within the Brain and Other Parts of the Body
  • Nervous System Tumors
  • Pancreatic Cancer
  • Prostate Cancer

SRS and SBRT are not options for everyone. Your care team will help determine if you are a candidate for this type of treatment.
