The incidence of both esophageal adenocarcinoma (EAC) and esophagogastric junctional adenocarcinoma (EGJA) has increased rapidly in the U.S. among Whites, while other esophageal cancer histological types have decreased. EAC and EGJA share many clinical, epidemiological and molecular features; however, despite well-established risk factors, the mechanisms by which these factors increase risk of EAC and EGJA are not well understood. This suggests a need to identify biomarkers that may serve as a link to understanding the mechanisms through which established risk factors, such as obesity and smoking, affect risk of EAC and EGJA. Recently, advances in the development of metabolite profiling technologies, or metabolomics, have emerged as a way to comprehensively study metabolism, metabolites and other small molecules in tissues and body fluids. Applications of metabolomic platforms in distinguishing disease states, such as cardiovascular disease and diabetes, have shown promise in furthering our understanding of mechanisms of disease.
Overall, there is limited data on the relationship between metabolic profiles and risk of EAC or EGJA. To the best of the NCI's knowledge, no studies have attempted a prospective analysis of metabolites in pre-diagnostic samples in relation to EAC or EGJA risk. The NCI will use a method that produces high-throughput results suitable for an epidemiologic study. Liquid chromatography/mass spectrometry (LC-MS) and gas chromatography/mass spectrometry (GC-MS) will be used for the detection of metabolites and is ideal for complex biofluids, such as blood. Among other features, MS methods allow for resolution of metabolites and the ability to focus on quantifying a single analyte or a small number of potentially relevant analytes in a biological sample. Results should provide the NCI an inroad into understanding the mechanisms underlying the etiology of EAC and EGJA.
The NCI will send 200 blood samples from EAC and EGJA cases and controls. Samples are to be run on both the Liquid Chromatography Mass-Spectrometry (MS) and Gas Chromatography MS platforms, with linkage of raw MS output to named and unnamed biochemicals.
The Contractor shall conduct metabolite measurements of 282 known metabolites and provide quantitative results. One aliquot of each serum sample will be shipped from the NCI biorepository to the contractor. At the facilities, 150 μL serum samples shall be analyzed simultaneously using liquid chromatography/mass spectrometry (LC/MS) followed by gas chromatography/mass spectroscopy to measure 282 known metabolites. Quantitative metabolite concentrations will be identified from the integrated raw detector counts from the mass spectrometers. Upon completion of specimen measurement and processing, quantitative metabolite concentrations shall be emailed to NCI.
This is a replication study. All previous assay work to measure metabolites within the NCI cohort studies have been conducted by Metabolon Inc. For scientific comparability in a replication study, it is critical that the laboratory measurements of these analytes be carried out in the same laboratory and on the same platform.
