Scientists hunt for genetic clues in prostate cancer blood samples
NCT ID NCT00923221
First seen Oct 31, 2025 · Last updated Jun 22, 2026 · Updated 35 times
Summary
This study collects blood samples from 1,000 men with prostate cancer to look for genetic differences that might explain why some cancers stop responding to hormone therapy. Participants give blood at clinic visits, and researchers analyze DNA and other genetic material. No treatment is given—the goal is to better understand the disease.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this research could help identify genetic markers that predict which prostate cancers may become harder to treat.
What could go wrong
This is an observational study, not a treatment trial. It may not lead directly to new therapies, and genetic findings may not apply to all patients.
