Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Polymorphisms in various pathways, DNA repair, free-radical formation, inflammatory genes, metastatic potential, and cell cycle or tumor suppression in blood samples [ Designated as safety issue: No ]
  • Comparison of presence or absence of variant polymorphisms between cases and controls [ Designated as safety issue: No ]
  • Correlation between polymorphisms in blood samples and polymorphisms in tissue specimens [ Designated as safety issue: No ]
  • Analyses of dietary factors and Helicobacter pylori infection (previous vs current) [ Designated as safety issue: No ]

Estimated Enrollment: 1000
Detailed Description:


  • 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.
