Brief 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.

Detailed 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 collection. Samples are studied by genetic and proteomic analyses, including comparative genomic hybridization, expression microarray, and protein profiling.

Interventions

PROCEDUREUrine collection

Subjects will be asked to provide a urine specimen.

Using a brush, superficial cells are removed from the nose.

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.

PROCEDUREBlood draw

Venous blood will be collected

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.

Design outcomes

Primary

MeasureTime frameDescription
To quantitate the molecular changes during lung cancer developmentAfter collection of designated samplesAs a part of the study nasal brushing specimens, sputum, blood, urine, and a small amount of other tissue will be collected during standard of care procedures (bronchial epithelial, trans-thoracic fine needle aspiration (FNA) and thoracentesis as part of patient work up. Clinical diagnosis is the primary goal of the procedure. All the research specimens are collected after the primary goal of the procedure is met.

Secondary

MeasureTime frameDescription
Develop a method to diagnose and stage pre-invasive and invasive lesionsAfter collection of designated samplesUse of proteomic techniques in the laboratory to find a method of diagnosing lung tissue as benign or malignant rather than relying on invasive open-chest surgery for a diagnosis
