      • Long segment Barrett's esophagus patients who have not progressed beyond low grade dysplasia
      • Cancer patients still living
      • Cancer patients who have passed away
    • Phenotype (3): TREATMENT phenotype
      • Using a proton pump inhibitor at the time of specimen collection
      • Status post chemotherapy
      • Status post radiation therapy
      • Status post combination chemoradiation therapy
