Timing tumor DNA tests after chemo: a small study
NCT ID NCT06141772
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study measured how levels of circulating tumor DNA (ctDNA) change in the hours after the first round of chemotherapy in 24 people with diffuse large B cell lymphoma. The goal was to find the best time to take blood samples for monitoring the cancer. Researchers hope that a better understanding of ctDNA timing could improve how doctors track 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 could help doctors know the best time to test for tumor DNA after chemotherapy, improving how they monitor the disease.
What could go wrong
This is a very small, completed study with only 24 participants. It is designed to gather information, not to test a new treatment, so it may not lead to any direct patient benefit.
