RATIONALE: Studying samples of blood in the laboratory from patients receiving erlotinib hydrochloride may help doctors learn more about the effects of erlotinib hydrochloride on cells. It may also help doctors understand how well patients respond to treatment.
PURPOSE: This research study is studying biomarkers predicting response in patients with non-small cell lung cancer previously treated with erlotinib hydrochloride.
- To evaluate whether serum NGAL, MMP-9, NGAL/MMP-9 complex, and soluble E-cadherin can be utilized as biomarkers to predict response in patients with non-small cell lung cancer treated with erlotinib hydrochloride.
OUTLINE: Serum samples are analyzed for NGAL, MMP-9, NGAL/MMP-9, and soluble E-cadherin by ELISA and Luminex assays.

An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
The assay of INTERFERON-GAMMA released from lymphocytes after their exposure to a specific test antigen, to check for IMMUNOLOGIC MEMORY resulting from a previous exposure to the antigen. The amount of interferon-gamma released is usually assayed by an ENZYME-LINKED IMMUNOSORBENT ASSAY.
A method of detection of the number of cells in a sample secreting a specific molecule. Wtih this method a population of cells are plated over top of the immunosorbent substrate that captures the secreted molecules.
A genotoxicological technique for measuring DNA damage in an individual cell using single-cell gel electrophoresis. Cell DNA fragments assume a "comet with tail" formation on electrophoresis and are detected with an image analysis system. Alkaline assay conditions facilitate sensitive detection of single-strand damage.
Techniques for removal by adsorption and subsequent elution of a specific antibody or antigen using an immunosorbent containing the homologous antigen or antibody.
