Blood Samples From Patients With Non-Small Cell Lung Cancer and From Healthy Volunteers

Completed
Conditions
Lung Cancer
Interventions
Other: Mass Spectrometry
Registration Number
NCT00897234
Lead Sponsor
University of Minnesota
Brief Summary

RATIONALE: Studying samples of blood 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 research study is looking at blood samples from patients with non-small cell lung cancer and from healthy volunteers.

Detailed Description

OBJECTIVES:

* Measure plasma cathepsin D levels in patients with non-small cell lung cancer and in healthy volunteers using mass spectometry.

* Measure fatty acid synthase levels in these patients and healthy volunteers using mass spectometry.

OUTLINE: Blood samples are collected from patients and healthy volunteers to measure the levels of cathepsin D and fatty acid synthase by proteomic profiling and mass spectrometry.
