Lung fluid may replace biopsies for cancer testing
NCT ID NCT04806412
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at fluid from around the lungs (pleural effusion) in people with non-small cell lung cancer. Researchers want to see how often important cancer markers like PD-L1, ALK, and EGFR can be found in that fluid. They will also check if the amount of fluid tested affects the results. The goal is to learn whether this fluid can be used instead of a tissue biopsy to choose the right treatment.
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 study could help doctors use pleural fluid instead of tissue biopsies to guide lung cancer treatment, reducing the need for invasive procedures.
What could go wrong
This is an observational study, not a treatment trial. It only measures existing markers and does not test a new therapy, so it won't directly improve outcomes.
