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.

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.

Ages Eligible for Study:  45 Years and above,  Genders Eligible for Study:  Both
