NCT ID NCT05523583
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at 165 adults newly diagnosed with lung or head & neck cancer who smoked. Researchers interviewed them by phone about their smoking and drinking habits, and followed up at 3, 6, and 12 months. The goal was to understand what makes it harder or easier for patients to quit, so better support can be offered.
