Diagnostic performances of pepsinogens and gastrin-17 for atrophic gastritis and gastric cancer in Mongolian subjects.

In Mongolia, gastric cancer morbidity and mortality are high, and more than 80 percent of cases are diagnosed at an advanced stage. This study aimed to evaluate pepsinogens (PGIs) and gastrin-17 (G-17) levels and to determine the diagnostic performances for gastric cancer and chronic atrophic gastritis among Mongolian individuals. We enrolled a total of 120 subjects, including gastric cancer (40), atrophic gastritis (40), and healthy control (40), matched by age (±2) and sex.

Determining Gastric Cancer-Related Risk Factors in Mongolian Population Using ABC(D) Method: A Matched Case-Control Study.

Objective: We aimed to identify gastric cancer-related risk factors and evaluate the efficacy of screening ABC(D) method in determining high risk  gastric cancer individuals in Mongolian population.

Methods: A total of 240 participants (120 gastric cancer patients and 120 healthy individuals) were included in this study. Data were collecting using a structured questionnaire consisting of 56 questions covering 5 categories.
