• severe
  • In moderate to severe antrum or body gastritis with atrophy, additional corpus biopsy resulted in increased sensitivity to 16.67% compare to single antrum biopsy. (biomedcentral.com)
  • In moderate to severe gastritis with atrophy, biopsy-based test should include the corpus for avoiding false negative results. (biomedcentral.com)
  • atrophy
  • This study aimed to evaluate the site and sensitivity of biopsy-based tests in terms of degree of gastritis with atrophy. (biomedcentral.com)
  • The sensitivity, specificity, positive predictive rate and negative predictive rate of biopsy-based tests at the gastric antrum and body were calculated in terms of degree of gastritis with atrophy. (biomedcentral.com)
  • This prospectively designed study used the combination method as gold standard to investigate the correlation among sensitivity of biopsy-based test, biopsy location, degree of gastritis with atrophy, and H. pylori prevalence rate. (biomedcentral.com)
  • junction
  • The cardia is defined as the region following the "z-line" of the gastroesophageal junction, the point at which the epithelium changes from stratified squamous to columnar. (wikipedia.org)
  • esophageal adenocarcinoma
  • Some studies suggested that H. pylori strains positive for Cag A (strains strongly associated with the development of corpus gastritis) may be particularly protective against the development of esophageal adenocarcinoma [ 7-9 ]. (uptodate.com)
