SBRT

What Is SBRT?

Stereotactic Body Radiation Therapy (SBRT) is an advanced form of external radiation that delivers high doses of radiation with extreme precision. Originally developed from techniques used in stereotactic radiosurgery for brain tumors, SBRT is now used to treat tumors throughout the body—especially those near sensitive organs or in areas prone to movement, like the chest and abdomen.

How It Works

Using 3D imaging and real-time tracking, SBRT pinpoints the exact shape, size, and location of a tumor—accurate to within 1–2 millimeters. Specialized equipment then delivers high-energy X-ray beams from multiple angles, concentrating the radiation on the tumor while minimizing exposure to nearby healthy tissue.

Technologies Behind SBRT

• 3D imaging for tumor mapping and localization
• Precise patient positioning and stabilization tools
• Real-time imaging using IGRT (Image-Guided Radiation Therapy)
• High-dose radiation beams sculpted to the tumor’s shape

When Is SBRT Recommended?

SBRT is often used as an alternative to surgery—especially for patients who are not surgical candidates or have hard-to-reach tumors. It is commonly used to treat:

• Lung cancer
• Liver cancer
• Pancreatic cancer
• Prostate cancer

Benefits of SBRT

• Fewer Treatment Sessions: Most SBRT treatments are completed in just 1–5 sessions over 1–2 weeks.
• Minimal Side Effects: Surrounding tissue is spared from excess radiation, helping reduce side effects.
• High Precision: Radiation is delivered only when the tumor is in the ideal position.

Potential Side Effects

SBRT is well tolerated by most patients, but side effects can vary based on the treatment area. For example:

• Lung cancer patients may experience a mild cough
• Liver or pancreatic patients may notice temporary nausea or diarrhea
• Prostate cancer patients may have increased urinary urgency

Your care team will work with you to manage any side effects and keep you comfortable throughout your treatment.
