Nerve-Sparing radiation may help men keep sexual function after prostate cancer treatment

NCT ID NCT03525262

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial is testing whether a special type of radiation therapy (SAbR) that avoids the nerves involved in erections can help preserve sexual function in men with localized prostate cancer. About 124 men will be randomly assigned to receive standard SAbR or a version that spares these nerves. The main goal is to see if the nerve-sparing approach leads to less decline in erectile function, while still controlling the cancer effectively.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Stereotactic ablative body radiotherapy (SAbR) with or without neurovascular sparing

What this could lead to

If successful, this approach could help men with prostate cancer maintain sexual function after radiotherapy without compromising cancer treatment.

What could go wrong

This is a phase 2 trial with only 124 participants, so results may not apply to everyone. The nerve-sparing technique might not preserve function as hoped, or could increase the risk of cancer recurrence in the spared area.
