PURPOSE: This research study is studying biomarkers in blood samples from patients with refractory non-small cell lung cancer previously treated with sorafenib tosylate.
- To determine the mutation rates of BRAF, KRAS, and EGFR in patients with non-small cell lung cancer treated with sorafenib tosylate on protocol ECOG-2501.
- To determine the association between BRAF, KRAS, or EGFR mutation status and clinical benefits in patients treated with this regimen.
OUTLINE: This is a multicenter study.
DNA is isolated from archived plasma samples and analyzed for BRAF, KRAS, and EGFR mutations.
DNA analysis, mutation analysis, laboratory biomarker analysis

A previous meta-analysis (MA) found postoperative radiotherapy (PORT) in lung cancer patients to be detrimental in N0/N1 patients and equivocal in the N2 setting. We hypothesized that treatment plans ...
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)
Meta-analysis of randomized trials in which estimates of comparative treatment effects are visualized and interpreted from a network of interventions that may or may not have been evaluated directly against each other. Common considerations in network meta-analysis include conceptual and statistical heterogeneity and incoherence.
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)
Methods for performing three-dimensional measurement and motion analysis using stereoscopic radiographs.
The simultaneous analysis, on a microchip, of multiple samples or targets arranged in an array format.
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
