Esophageal Cancer Clinical Trial
Genetic and Environmental Risk Factors Related to Esophageal Cancer
Summary
RATIONALE: Gathering information about genes, cigarette smoking, and diet may help doctors learn more about risk factors that may cause esophageal cancer.
PURPOSE: This clinical trial is studying genetic and environmental risk factors related to esophageal cancer.
Full Description
OBJECTIVES:
Examine the role of several genetically-determined factors in combination with cigarette smoking and diet in the etiology and prevention of esophageal cancer.
Identify polymorphisms in metabolizing enzymes (e.g., phase I or II metabolism [GSTM1, GSTT1,CYP1A1, CYP3A5, mEH, NQO1, GSTP1], DNA repair [XRCC1, ERCC2], free-radical formation [MPO, MnSOD], inflammatory genes [ IL1-beta], metastatic potential [MMP1], and cell cycle or tumor suppression [p21, p53]) and related path genes of susceptibility for esophageal cancer.
OUTLINE: Blood and tumor tissue samples are collected. DNA purified from these samples is analyzed using DNA-based assays to determine polymorphisms in various related gene pathways.
Patients complete questionnaires concerning environmental, smoking and diet habits.
PROJECTED ACCRUAL: A total of 1,000 tissue samples from patients and healthy participants (750 patients and 250 healthy participants) will be accrued for this study.
