Webinar Recap: Augmented SBRT for Prostate Cancer
Date: September 25, 2025
On September 25th, leading oncology experts gathered virtually to share the latest advancements in precision techniques for prostate cancer treatment. The webinar featured insightful presentations focused on improving patient outcomes while minimizing side effects.
Here’s a summary of the main conclusions shared by the speakers:
Prof. Filippo Alongi
- MRgRT is a concrete and available option for precision RT in several clinical settings.
- The advantages of MR imaging over CBCT are evident (not only) in soft tissue and are crucial in many cases for improving precision.
- MR adaptive capabilities are robust and useful for real-time organ sparing and PTV targeting.
- Real tumor tracking is feasible and reliable without impacting treatment time.
- New potential indications are emerging. Our experience with more than 1,000 patients confirms the value of this new approach as a step forward in SBRT.

Prof. Stefano Arcangeli
Augmented prostate SBRT requires:
- Careful patient selection
- High-resolution imaging
- Dose escalation for higher-risk tumors
- Monitoring and correction of target motion
- Reducing exposure to the intraprostatic urethra

Prof. Thomas Zilli
Augmented SBRT with a single fraction:
- Feasible
- Non-invasive
- With low side effects (urethra-sparing & intrafraction motion control)
- With minimal impact on quality of life
However, longer follow-up and further studies are needed before single-fraction treatment can be considered an alternative option.

Prof. Giulia Marvaso
- SBRT is an attractive, non-invasive option for selected patients.
- SBRT is competitive with surgery or ADT in terms of tumor control and toxicity.
- Wider use is expected.
- While awaiting more evidence, the ESTRO ACROP consensus can serve as a helpful guide for practitioners.

Prof. Piet Ost
Improving patient outcomes through technology is possible:
- Improved planning and delivery with SBRT reduces dose to organs at risk, improves target coverage, lowers toxicity, and enhances outcomes.
- Improved image guidance and adaptation with ASBRT further reduces margins, lowering dose to organs at risk, reducing toxicity (mostly bowel), and improving target coverage and outcomes.
- Improved patient selection can also optimize results. Thorough patient assessment prior to radiotherapy helps identify the ideal candidates.
