RATIONALE: Studying the genes expressed in samples of blood and lung fluid in the laboratory from patients receiving budesonide and formoterol may help doctors learn more about the effect of budesonide and formoterol on gene expression and biomarkers.
PURPOSE: This clinical trial is studying genes in blood and lung fluid samples from patients with chronic obstructive pulmonary disease, with or without a previous diagnosis of lung cancer, or with asthma treated with budesonide and formoterol.
Full description
OBJECTIVES:
OUTLINE: Patients receive budesonide/formoterol fumarate dihydrate inhalation aerosol (Symbicort Turbuhaler) twice daily for 4 weeks in the absence of disease progression or unacceptable toxicities.
Patients undergo blood sample collection and bronchoscopy at baseline and at 4 weeks. Blood and bronchoalveolar fluid samples are analyzed for inflammatory biomarker measurements. Bronchial brushing cell samples are analyzed by comparative genomic hybridization array, whole genome methylation array, and gene expression profiling.
After completion of study treatment, patients are followed at 1 week by telephone interview.
