About this study

Official title: A Pilot Project to Study the Expression of c-MET and p53 in Resected Lung Adenocarcinoma Specimens

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.

Read the detailed description

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.

OUTLINE: This is a multicenter study.

Previously collected tissue samples from patients enrolled in CALGB 140202 are assessed for mutation analysis of c-Met, EGFR, and K-ras. DNA is examined by PCR, followed by agarose gel electrophoresis; gene amplification of c-Met is examined by real time quantitative PCR; met/HF protein in serum is examined by ELISA; and c-Met, EGFR, p53, c-CBL, DUB3 enzyme, and ALK, and epithelial mesenchymal transition examined by IHC.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. c-Met expression

    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.

    Measured: Baseline

Secondary outcomes (8)
  1. EMT expression

    The correlation of EMT, EGFR mutations and expression, Kras mutations, p53 mutations, c-CBL protein expression, mutation, and LOH, DUB3 expression, and ALK translocation, circulating c-Met and HGF with respect to survival will be evaluated by Cox model with these markers as continuous predictors or by log rank test with these biomarkers dichotomized at certain cutoff points, such as median or ad hoc optimal cutoff points.

    Measured: Baseline

  2. Mutations in EGFR, Kras, p53, and c-CBL

    The correlation of EMT, EGFR mutations and expression, Kras mutations, p53 mutations, c-CBL protein expression, mutation, and LOH, DUB3 expression, and ALK translocation, circulating c-Met and HGF with respect to survival will be evaluated by Cox model with these markers as continuous predictors or by log rank test with these biomarkers dichotomized at certain cutoff points, such as median or ad hoc optimal cutoff points.

    Measured: Baseline

  3. c-CBL expression and LOH

    The correlation of EMT, EGFR mutations and expression, Kras mutations, p53 mutations, c-CBL protein expression, mutation, and LOH, DUB3 expression, and ALK translocation, circulating c-Met and HGF with respect to survival will be evaluated by Cox model with these markers as continuous predictors or by log rank test with these biomarkers dichotomized at certain cutoff points, such as median or ad hoc optimal cutoff points.

    Measured: Baseline

  4. DUB3 expression and regulation

    The correlation of EMT, EGFR mutations and expression, Kras mutations, p53 mutations, c-CBL protein expression, mutation, and LOH, DUB3 expression, and ALK translocation, circulating c-Met and HGF with respect to survival will be evaluated by Cox model with these markers as continuous predictors or by log rank test with these biomarkers dichotomized at certain cutoff points, such as median or ad hoc optimal cutoff points.

    Measured: Baseline

  5. ALK Translocation

    The correlation of EMT, EGFR mutations and expression, Kras mutations, p53 mutations, c-CBL protein expression, mutation, and LOH, DUB3 expression, and ALK translocation, circulating c-Met and HGF with respect to survival will be evaluated by Cox model with these markers as continuous predictors or by log rank test with these biomarkers dichotomized at certain cutoff points, such as median or ad hoc optimal cutoff points.

    Measured: Baseline

  6. Circulating c-Met and HGF in AC

    The correlation of EMT, EGFR mutations and expression, Kras mutations, p53 mutations, c-CBL protein expression, mutation, and LOH, DUB3 expression, and ALK translocation, circulating c-Met and HGF with respect to survival will be evaluated by Cox model with these markers as continuous predictors or by log rank test with these biomarkers dichotomized at certain cutoff points, such as median or ad hoc optimal cutoff points.

Questions about this trial

What is this clinical trial studying?

An observational study of Lung Cancer, run by Alliance for Clinical Trials in Oncology at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

c-Met expression (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2017.
