What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

Researchers at Vietnam National Cancer Hospital are testing whether adding one structured cognitive behavioral therapy (CBT) session to standard brief counseling helps cancer patients remain smoke-free. The trial enrolls 498 adults who smoked at cancer diagnosis and have stayed completely abstinent since. All participants receive brief relapse-prevention counseling, then half are randomly assigned to also get a single CBT-based session. The study follows participants for three months to see who avoids smoking even a puff.

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 (CBT) session for smoking relapse prevention
What this could lead to
If it works, this could offer a low-cost, easy-to-deliver way to help cancer patients stay smoke-free after quitting at diagnosis, potentially improving treatment outcomes and quality of life.
What could go wrong
This is a small, short-term study in one hospital in Vietnam, so results may not apply to other settings or patient groups. The extra CBT session may not add enough benefit beyond standard brief counseling, and self-reported abstinence can be less reliable than biological testing.
