Scientists hunt for cancer clues in sputum and tissue samples
NCT ID NCT00900419
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This research study collects sputum and tissue samples from 700 people with precancerous changes or certain cancers (lung, head and neck, esophageal). The goal is to find biomarkers—biological signs—that could help understand or detect these cancers earlier. Participants include those with severe dysplasia and those without it, for comparison.
