Blood test may reveal how rare cancer responds to treatment
NCT ID NCT07793240
First seen Aug 28, 2026 · Last updated Sep 02, 2026 · Updated 2 times
Summary
Researchers at Johns Hopkins are testing whether a blood test called Signatera can reliably detect tumor DNA in people with high-grade upper tract urothelial cancer, a rare cancer of the urinary tract. The study will collect blood samples before, during, and after treatment to see if changes in tumor DNA levels match how well the cancer responds. The goal is to learn whether this test can help design better future trials for perioperative therapy in this disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Signatera testing, a blood test that looks for tumor DNA fragments (ctDNA)
- What this could lead to
- If the test proves reliable, it could help doctors monitor how well treatment works and design better clinical trials for this rare cancer.
- What could go wrong
- This is a small, early study with only 20 participants. The test may not always detect cancer or match with patient outcomes, and it is not yet a proven tool for guiding treatment.
