Brief summary
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. Celecoxib may be effective in preventing lung cancer in tobacco smokers. PURPOSE: Phase II trial to study the effectiveness of celecoxib in preventing non-small cell lung cancer in tobacco smokers.
Detailed description
OBJECTIVES: * Determine the efficacy and feasibility of celecoxib for chemoprevention of primary non-small cell lung cancer in high-risk tobacco smokers. * Determine the safety and long-term side effects of this drug in this population. OUTLINE: Patients receive oral celecoxib twice daily for 6 months. Patients are followed at 2 weeks and then at 6 months. PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study within 6 months.
Interventions
Dosing will occur for a total of 6 months. 400 mg by mouth twice daily.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluate the expression of Cox-2 and PGE2 in the lungs of tobacco smokers. | 1 year |

Secondary
| Measure | Time frame |
|---|---|
| Determine the effects of Cox-2 inhibition on biomarkers of field cancerization on histopathologic abnormalities in patients at risk for primary NSCLC | 2 years |
| Study the potential role of PGE2 and its regulation by Cox-2 specific inhibitors on antitumor immunity within the lung microenvironment | 2 years |
