Stopping smoking before bronchoscopy or CT‑guided lung biopsy

Smoking Cessation Before Intervention in Patients With Pulmonary Nodules Requiring Further Diagnosis

RWTH Aachen University · NCT07322796

This project tests whether offering immediate quit-smoking support and measuring nicotine markers helps people who smoke and are having a bronchoscopy or CT‑guided lung biopsy stop smoking.

What this trial studies

This is an observational program for people who currently smoke and present with a suspicious round lung lesion; they are urgently advised to quit and offered connections to smoking‑cessation counseling and pharmacotherapy if desired. Nicotine dependence is measured with the Fagerström test and biochemical markers (COHb from blood gas and urine cotinine) are taken at baseline, at the planned result discussion after inpatient histological confirmation (bronchoscopy or CT‑guided puncture), and again at 3 months. The team also records age, gender, height, weight, medications, comorbidities, and body plethysmography data. Participation does not change the clinical course or treatment decisions for the diagnostic workup.

Who should consider this trial

Good fit: Active smokers who present to the pneumology outpatient clinic for evaluation of a suspicious pulmonary nodule and who are willing to participate in counseling and biochemical testing are ideal candidates.

Not a fit: People who do not smoke, who are unwilling to engage in cessation efforts, or who have medical conditions or treatments that make study measurements unevaluable are unlikely to benefit from this program.

Why it matters

Potential benefit: If successful, more patients with suspicious lung nodules may quit smoking, lowering their future risk of tobacco‑related illness and improving overall health outcomes.

How similar studies have performed: Smoking-cessation counseling with biochemical verification has helped smokers quit in other clinical settings, although applying it specifically around bronchoscopy or CT‑guided biopsy timing is relatively novel.
