简要总结
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This laboratory study is looking at tumor samples from patients with lung cancer.
详细描述
OBJECTIVES:
Primary
- To determine the correlation between c-Met expression, mutation and amplification, with stage and overall survival in patients with adenocarcinoma (AC) of the lung.
Secondary
- To determine the correlation with epithelial mesenchymal transition (EMT), EGFR mutations and expression, Kras mutations, p53 mutations, c-CBL protein expression, mutation, loss of heterozygosity (LOH), DUB3 expression & regulation, and ALK translocation, with respect to survival.
- To determine the correlation with circulating c-Met and HGF in AC and evaluate prognostic implications of circulating markers in AC of lung.
- To determine (when available) levels of circulating Met and HGF in serum before and after surgery.

入选标准
- •Registration to Cancer and Leukemia Group B (CALGB) 140202
- •Institutional Review Board (IRB) review and approval at the institution where the laboratory work will be performed is required
- •Informed consent: the CALGB does not require that a separate consent form be signed for this study
- •The subject population to be studied in this protocol includes patients selected from CALGB 140202; all such patients have signed a written informed consent document meeting all federal, state, and institutional guidelines as part of entry into that trial
- •All samples to be studied were obtained and stored as part of CALGB 140202; the material and data obtained from the patient's protocol record will be used to obtain appropriate clinical information; in no instance will the patient be contacted directly
- •There should be no physical, psychological, social, or legal risks associated with this study; no invasive procedures are recommended or requested
- •All appropriate and necessary procedures will be utilized to maintain confidentiality; all patients who have had samples submitted for analysis will have their CALGB study number used to identify specimens
- •This study does not require direct patient contact and no specific risk or benefits to individuals involved in the trial are anticipated; it is likely, however, that the information gained will substantially help similar patients in the future

结局指标
主要结局
c-Met expression
时间窗: Baseline
The correlation of c-Met expression and stage will be tested using Fisher's exact test. The proportions of c-Met overexpressed in stage I and stage II or higher will be estimated as well as the confidence intervals. The correlation of c-Met expression and survival will be tested using log rank test. The hazard ratio and its confidence interval will be estimated using a Cox model with a single predictor. Summary statistics will be provided for all c-Met measures.
