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 pancreatic cancer
For pancreatic cancer patients who aren’t able to undergo surgery, our advanced technologies like SBRT allow us to deliver radiation with pinpoint accuracy to medically inoperable tumors, or to tumors that have recurred after previous radiation treatments.
Prior to SBRT treatment, the technology’s specially designed coordinate system precisely locates the tumor to ensure proper placement of tiny seed-like tracking devices. These seeds track the radiation, and help to reduce damage to surrounding healthy tissues.
During SBRT, we use the Trilogy™ system to deliver concentrated, highly focused radiation treatments. SBRT uses custom mapping to account for a patient’s anatomy, breathing and organ motion.
Depending on your personal pancreatic cancer treatment plan, our doctors may use SBRT to deliver a single high dose of radiation, or a few fractionated radiation doses (usually up to five treatments over a period of days).
