Stereotactic Body Radiotherapy

SBRT precisely targets prostate cancer with fewer sessions, reducing side effects and treatment time.
It’s ideal for patients with low- to intermediate-risk prostate cancer seeking effective and convenient care.

Stereotactic Body Radiotherapy (SBRT) for Prostate Cancer

SBRT is an advanced radiation treatment that precisely delivers high-dose radiation to prostate tumors in fewer sessions. This targeted approach reduces side effects and offers convenience for patients with low-risk and intermediate-risk prostate cancer.

What Is SBRT?

Stereotactic Body Radiotherapy (SBRT) uses specialized imaging and advanced technology to target prostate cancer accurately. It delivers a very high dose of radiation directly to cancer cells while sparing healthy tissue.

SBRT typically involves only five or fewer treatment sessions, making it a shorter and more convenient option compared to traditional radiation therapy.

Latest Research on SBRT

Recent studies highlight SBRT as a safe and effective option for treating low-risk and intermediate-risk prostate cancer:

  • A large study involving over 2,000 men showed SBRT provided excellent long-term control of prostate cancer with minimal severe side effects.
  • The PACE-B clinical trial demonstrated that SBRT delivered in five sessions was just as effective as traditional longer-course radiation therapy, maintaining excellent biochemical control.
  • Emerging research suggests even shorter SBRT protocols (such as two-session treatments) may become common practice for intermediate-risk prostate cancer patients in the future.

Benefits of SBRT

  • Fewer Treatment Sessions: Typically only 5 sessions or fewer, compared to weeks of traditional radiation therapy.
  • Highly Accurate: Advanced imaging precisely targets cancer, sparing healthy tissue.
  • Convenience: Shorter overall treatment time allows patients to quickly return to their normal lives.

Possible Side Effects of SBRT

SBRT has fewer side effects due to its precision, but some temporary effects may include:

  • Mild urinary irritation or increased urgency
  • Temporary bowel changes
  • Fatigue, usually mild and temporary

Most side effects improve within weeks after treatment ends.

Is SBRT Right for You?

SBRT is best suited for patients with:

  • Low-risk prostate cancer
  • Intermediate-risk prostate cancer
  • Few urinary symptoms

Discuss your eligibility with your radiation oncologist, who can help determine if SBRT is the best treatment option for your situation.

SBRT offers a precise, convenient, and effective treatment for prostate cancer, supported by strong evidence of long-term success.
