RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and RNA and identify biomarkers related to cancer.
PURPOSE: This laboratory study is looking at biomarkers in tumor tissue and blood samples from patients with non-small cell lung cancer.
Condition or disease | Intervention/treatment |
---|---|
Lung Cancer | Genetic: DNA analysis Genetic: RNA analysis Genetic: fluorescence in situ hybridization Genetic: gene expression analysis Genetic: mutation analysis Genetic: polymerase chain reaction Genetic: reverse transcriptase-polymerase chain reaction Other: laboratory biomarker analysis |
OBJECTIVES:
Primary
- Identify mutations in epidermal growth factor receptor (EGFR) in non-small cell lung cancer specimens from clinical trial CASE-2507.
- Investigate EGFR DNA copy-number changes.
- Determine abnormalities of other pathways, such as the c-MET and PI3K pathways as potential mechanisms of resistance.
OUTLINE: This is a multicenter study.
DNA and RNA are extracted from tumor samples. Genomic DNA is analyzed using real-time PCR/ reverse transcriptase PCR analysis and/or FISH analysis in order to study resistance mechanisms such as secondary EGFR mutations and the c-MET and PI3K pathways. RNA is analyzed using TaqMan quantitative PCR in order to determine the copy number of EGFR expressed in these tissues. Peripheral blood samples are used to isolate peripheral blood mononuclear cells positive for epithelial cell adhesion molecule (EpCAM).
