Calcitriol in Preventing Lung Cancer in Smokers and Former Smokers at High Risk of Lung Cancer
RATIONALE: Calcitriol may prevent lung cancer in patients with metaplasia or dysplasia of the lungs.
PURPOSE: This clinical trial is studying the side effects and best dose of calcitriol in preventing lung cancer in current smokers and former smokers at high risk of lung cancer.

- To establish the safety of calcitriol in patients at high risk of lung cancer.
- To determine the dose-limiting toxicities of calcitriol in these patients.
OUTLINE: Patients receive oral calcitriol on day 1. Courses repeat every 2 weeks for 3 months in absence of unacceptable toxicity.
Patients undergo blood collection periodically for pharmacokinetic and molecular analysis.
After completion of study therapy, patients are followed periodically.
