Study of Tissue Samples From Patients With Stage I Non-Small Cell Lung Cancer Enrolled on Research Study CALGB-140202
Recruitment status was Active, not recruiting
RATIONALE: Studying the genes expressed in samples of tumor tissue from patients with cancer may help doctors identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.
PURPOSE: This research study is looking at tissue samples from patients with stage I non-small cell lung cancer enrolled on research study CALGB-140202.
Genetic: gene expression analysis
Genetic: microarray analysis
Genetic: reverse transcriptase-polymerase chain reaction
Other: laboratory biomarker analysis
|Official Title:||A Validation of the 64-Gene Signature Using Affymetrix-HG_U133A Array in Stage I NSCLC From the CALGB Lung Cancer Study (140202)|
- Overall survival, defined as the time from surgery to death of any cause [ Designated as safety issue: No ]
- Disease-free survival, defined as time from surgery to any recurrence (local or regional), second primary tumor, distant metastasis, or death of any cause [ Designated as safety issue: No ]
|Study Start Date:||July 2009|
- Determine whether the 64-gene signature can accurately predict the prognosis for survival of patients with stage I non-small cell lung cancer (NSCLC).
OUTLINE: RNA is purified from tissue samples obtained by the CALGB Lung Cancer Study (CALGB-140202). The RNA samples are used for gene expression analysis using the 64-gene signature and an Affymetrix-HG_U133A array. Reverse-transcriptase PCR may also be performed on selected samples.
