Biomarkers and Dysplastic Respiratory Epithelium
University of Colorado, Denver
Summary
RATIONALE: Studying samples of sputum and tissue in the laboratory from patients with dysplasia or cancer may help doctors identify and learn more about biomarkers related to cancer. It may also help the study of cancer in the future. PURPOSE: This laboratory study is looking at biomarkers in patients with respiratory tract dysplasia or lung cancer, head and neck cancer, or aerodigestive tract cancer.
Description
OBJECTIVES: Primary * Determine intermediate biomarkers of premalignant respiratory epithelial lesions, such as genetic mutations or altered growth factor expression, in patients with dysplasia of the respiratory epithelium or lung cancer, head and neck cancer, or aerodigestive tract cancer. Secondary * Establish a tissue repository of normal and dysplastic respiratory epithelium from endobronchial forceps and brush biopsy tissue from these patients and from normal volunteers. OUTLINE: Patients are stratified according to presence of extensive and severe dysplasia of the respiratory epith…
