This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This early trial tested a less invasive treatment for prostate cancer called microwave ablation, which uses heat to kill tumor cells. One man with prostate cancer received the ablation before his scheduled prostate removal surgery. The goal was to see if the procedure is safe and how much tissue it kills, which could lead to a treatment that avoids major surgery and its side effects.

What this could mean

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

Active substance
microwave ablation
What this could lead to
If this approach works, it could point toward a less invasive treatment for prostate cancer that avoids major surgery and its side effects.
What could go wrong
This was a very small, early study with only one participant, so results may not apply to others. The procedure also carries risks like bleeding or infection.
