First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to find genetic changes in lung tissue and blood that could predict how squamous cell lung cancer progresses. Researchers planned to collect samples from 200 patients undergoing lung procedures, but the study was stopped early with only 22 participants. No treatment was given; the goal was purely to gather information.
