Correlations among endoscopic, histologic and serologic diagnoses for the assessment of atrophic gastritis

Atrophic gastritis is a precancerous condition, which can be diagnosed by several methods. However, there is no consensus for the standard method. The aim of this study was to evaluate the correlations among endoscopic, histologic, and serologic findings for the diagnosis of atrophic gastritis. From March 2003 to August 2013, a total of 2,558 subjects were enrolled. Endoscopic atrophic gastritis was graded by Kimura-Takemoto classification and histological atrophic gastritis was assessed by updated Sydney system. Serological assessment of atrophic gastritis was based on serum pepsinogen test. The serum pepsinogen I/II ratio showed a significant decreasing nature when the extent of atrophy increased (R(2)=0.837, P
