Molecular Predictors of Lung Cancer Behavior
Vanderbilt-Ingram Cancer Center
Summary
RATIONALE: Using samples of blood, urine, sputum, and lung tissue from patients at high risk of cancer for laboratory studies may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at molecular predictors of cancer in patients at high risk of lung cancer.
Description
OBJECTIVES: * To use fixed lung tissue for histological evaluation and fresh tissue samples for molecular studies to study DNA, RNA, and protein abnormalities in lung preneoplastic and neoplastic lesions. * To use proteomic techniques, including matrix-assisted laser desorption ionization-mass spectrometry (MALDI-MS), to develop a method of diagnosing and staging both pre-invasive and invasive lesions, using less invasive methods. OUTLINE: Blood, urine, nasal cell, and sputum samples are collected. Lung tissue samples are also collected using fluorescence bronchoscopy and epithelial cell col…

Interventions
- Geneticcomparative genomic hybridization
Collection of sputum, blood, urine, and a small amount of lung tissue.
- Geneticgene expression microarray analysis
Collection of sputum, blood, urine, and a small amount of lung tissue.
- Geneticproteomic profiling analysis
Collection of sputum, blood, urine, and a small amount of lung tissue.
- Otherbiologic sample preservation procedure
Collection of sputum, blood, urine, and a small amount of lung tissue.
- Procedurenasal brushing
Using a brush, superficial cells are removed from the nose.
- ProcedureBlood draw
Venous blood will be collected
- ProcedureUrine collection
Subjects will be asked to provide a urine specimen.
- Proceduresputum sample
Prior to their bronchoscopy, subjects will be asked for a sputum specimen. This is a collection of mucous that you cough up.
- Procedurefluorescence bronchoscopy with airway biopsy
A flexible tube attached to a fluorescent light source will be inserted into the subject's mouth or nose to reach the airway. Samples of the lining of the airway will be taken, as well as bronchial secretions and epithelial cell from brushings of the lining of the airway.
- Procedurefine needle aspiration of the lung
A small needle is inserted into the lung to collect tissue. This procedure will only be performed if the patient's physician orders it.
- Procedurethoracentesis
A small needle is inserted into the patient's lung cavity and a small amount of fluid is collected. This procedure will only be performed if the patient's physician orders it.
