|Official Title:||The Identification, Validation and Implemention of Prognostic and/or Predictive Biomarkers for Adjuvant Chemotherapy in Early Stage Non-Small Cell Lung Cancer (NSCLC)|
- Validation of the 15-gene prognostic and predictive mRNA signature by quantitative Nuclease Protection Assay (qNPA) assay and NanoString assay [ Time Frame: Post-RNA extraction from tissue ]
- Prognostic and predictive value of known potential oncogenic mutations and gene copy variations of novel genomic aberrations on disease free survival (DFS) and overall survival (OS) [ Time Frame: Post-RNA extraction from tissue ]Survival curves will be estimated using Kaplan-Meier methods and compared with the log-rank test. The hypothesis of constant risk ratio over time in the Cox proportional hazards (PH) model will be tested by introducing a time-dependent interaction with the marker or using Schoenfeld's residuals.

Ancillary-Correlative (laboratory biomarkre analysis)
Archived RNA and DNA samples are analyzed for gene expression, mutations, and variations by RT-qPCR, MassARRAY, molecular inversion probe assay, and microarray assays. Results are then compared with patients' clinical outcomes.

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.
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.
