简要总结
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.
详细描述
OBJECTIVES:
Primary
- 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.
