Stereotactic Body Radiation Therapy
Dr. Michael Payne, a radiation oncologist at Cancer Treatment Centers of America, discusses stereotactic body radiation therapy.
Stereotactic Body Radiation Therapy (SBRT) for Prostate Cancer
We use a form of external beam radiation therapy called stereotactic body radiation therapy (SBRT) to treat tumors in the prostate with pinpoint accuracy.
Prior to receiving SBRT thearpy, the technology’s specially designed coordinate system will precisely locate the tumor to ensure proper placement of tiny seed-like tracking devices. These seeds track the radiation, and help to spare the surrounding healthy tissues from radiation exposure.
During SBRT, we use the Calypso® system to deliver concentrated, highly focused prostate cancer radiation therapy. Our doctors may deliver a single high dose of radiation, or a few fractionated radiation doses (usually up to five treatments over a period of days).
SBRT offers a promising option for patients who have early-stage prostate cancer. This technology may also be used to treat medically inoperable tumors or tumors that have recurred after previous radiation treatments.
Advantages of SBRT
- SBRT therapy uses custom mapping to account for a patient’s anatomy, breathing and organ motion.
- SBRT allows us to treat prostate tumors with less damage to healthy prostate tissue and nearby critical organs, like the bladder and rectum.
- During SBRT prostate cancer treatments, we can deliver a high-dose radiation treatment, so patients are often able to complete their therapy in a shorter time than with standard radiation treatment.
