SBRT for prostate cancer

What is SBRT?

Stereotactic body radiation therapy (SBRT) uses advanced imaging techniques to deliver a targeted radiation dose to a tumor. The radiation is focused on the tumor with millimeter precision. The result is that less healthy tissue gets damaged by radiation. Preserving healthy tissue is important for cancer patients whose tumors are near or in essential organs.

How it works

Before treatment, markers are placed around the tumor. SBRT uses an advanced coordinate system to precisely locate the tumor to ensure proper placement of the tracking devices. During treatment, we deliver concentrated, highly focused radiation treatment. The custom mapping provided by the coordinate system plans the radiation to account for a patient's anatomy, breathing and organ motion.

Throughout the treatment, the intensity and direction of the beams are constantly modulated to target the tumor and spare healthy tissue. The beams are also adjusted for any movement from breathing or digestion.

SBRT may be used to deliver a single high dose of radiation, or several fractionated radiation doses (usually up to five treatments over a period of days).

SBRT for prostate cancer

During SBRT for prostate cancer, we use the Calypso® system to deliver concentrated, highly focused prostate cancer radiation therapy.

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.
