Primary Outcome Measures:
  • The prevalence of early gastric cancer in gastric intestinal metaplasia(GIM) patient from 5 year-follow-up in Thai population [ Time Frame: Up to 5 years ]
    In Thailand, gastric cancer patients usually presented with advance stage and carried the dismal prognosis. GIM is a well known precancerous lesion. The appropriate follow-up period in high risk GIM patient can increase the prevalence of early gastric cancer and reduce the mortality rate of gastric cancer
