Blood test may spot returning prostate cancer earlier
NCT ID NCT07334275
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a special blood test can find tiny bits of tumor DNA left after prostate cancer surgery. The goal is to see if this test can better predict if the cancer will come back early in high-risk patients. About 50 men with high-risk prostate cancer will give blood samples before and after surgery to check for this DNA.
