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.

次要结局

  • EMT expression(Baseline)
  • Mutations in EGFR, Kras, p53, and c-CBL(Baseline)
  • Circulating c-Met and HGF in AC(Baseline)
  • c-CBL expression and LOH(Baseline)
  • DUB3 expression and regulation(Baseline)
  • ALK Translocation(Baseline)
  • Prognostic implications of circulating markers in AC of lung(Baseline)
  • Levels of circulating Met and HGF in serum before and after surgery (when available)(At time of surgery)
