Can a single talk session help cancer patients quit smoking?
NCT ID NCT07822464
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers test whether adding one structured cognitive behavioral therapy session to standard brief quit-smoking advice helps cancer patients stop smoking. The trial enrolls 446 adults with cancer in Vietnam who smoked at diagnosis and still smoke. Everyone gets brief counseling, and half also receive a longer CBT-based session. The main goal is to see who reports not smoking at all in the week before a three-month check-in.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a single structured cognitive behavioral therapy session for smoking cessation, added to brief quit-smoking counseling
- What this could lead to
- If it works, this could offer a low-cost way to help cancer patients quit smoking, which may improve their treatment outcomes and quality of life.
- What could go wrong
- The trial relies on self-reported smoking, with no biochemical checks, so some people may not report accurately. A single counseling session may not be enough to help people quit, especially during cancer treatment.
