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

Summary

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.
