OBJECTIVES:
I. Validation of the 15-gene prognostic and predictive messenger (m) ribonucleic acid (RNA) signature on Lung Adjuvant Cisplatin Evaluation (LACE)-Bio formalin-fixed, paraffin-embedded tissue (FFPE) tumor samples.
II. Exploratory evaluation of the prognostic and predictive values of known potential oncogenic mutations using LACE-Bio FFPE tumor samples.
III. Exploratory evaluation of the prognostic and predictive values of gene copy variations using LACE-Bio FFPE tumor samples.
IV. Exploratory identification and evaluation of prognostic and predictive value of novel genomic aberrations discovered by Next Generation Sequencing on LACE-Bio tumor samples.
OUTLINE:
Archived RNA and DNA samples are analyzed for gene expression, mutations, and variations by reverse transcriptase (RT)-polymerase chain reaction (qPCR), mass spectrometry (MassARRAY), molecular inversion probe assay, and microarray assays. Results are then compared with patients' clinical outcomes.
