Protein and RNA Expression Patterns in Predicting Response to Treatment in Patients With Lung Cancer
RATIONALE: Studying samples of tumor tissue and blood in the laboratory from patients with cancer may help doctors learn more about changes that occur in RNA and identify protein expression patterns related to cancer. It may also help doctors predict how patients will respond to treatment.
PURPOSE: This research study is looking at protein and RNA expression patterns in predicting response to treatment in patients with lung cancer.
- To determine protein and/or RNA expression patterns capable of predicting tumor response to therapy in tumor tissue samples from patients with lung cancer or suspected of having lung cancer.
- To characterize the genes and proteins found to be predictive of response in order to help elucidate the molecular biology underlying cancer chemosensitivity.
OUTLINE: Patients undergo collection of tumor tissue by percutaneous fine needle aspiration, core biopsy, or during any medically indicated procedure involving removal of lung tissue. Tissue samples are analyzed by MALDI-MS and RNA microarrays for protein and gene expression patterns and for identification of genes and proteins predictive of treatment response. Blood samples are also collected to obtain normal DNA for analysis.
After completion of study, patients are followed periodically.

Medical and Biotech [MESH] Definitions
The simultaneous analysis, on a microchip, of multiple samples or targets arranged in an array format.
A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Molecular Diagnostic Techniques
MOLECULAR BIOLOGY techniques used in the diagnosis of disease. Included are such techniques as IN SITU HYBRIDIZATION of chromosomes for CYTOGENETIC ANALYSIS; OLIGONUCLEOTIDE ARRAY SEQUENCE ANALYSIS of gene expression patterns in disease states; identification of pathogenic organisms by analysis of species specific DNA sequences; and detection of mutations with POLYMERASE CHAIN REACTION.
Analysis based on the mathematical function first formulated by Jean-Baptiste-Joseph Fourier in 1807. The function, known as the Fourier transform, describes the sinusoidal pattern of any fluctuating pattern in the physical world in terms of its amplitude and its phase. It has broad applications in biomedicine, e.g., analysis of the x-ray crystallography data pivotal in identifying the double helical nature of DNA and in analysis of other molecules, including viruses, and the modified back-projection algorithm universally used in computerized tomography imaging, etc. (From Segen, The Dictionary of Modern Medicine, 1992)
A multistage process that includes the determination of a sequence (protein, carbohydrate, etc.), its fragmentation and analysis, and the interpretation of the resulting sequence information.
