 The serum ABC classification determined by measuring serum H. pylori IgG antibody and serum pepsinogen levels is a simple and scientifically reliable method for mass screening of gastric cancer, by which a lower risk group of those not infected with H. pylori, Group A, is excluded from further endoscopic examination, and higher risk groups(Groups B, C, and D)are subjected to further endoscopic examination. The quality of images obtained by transnasal endoscopy is fully acceptable, and the present investigation indicated that the detection rate for gastric cancer was found to be a close equivalent to that of transoral high vision endoscopy. Furthermore, the serum ABC classification must be confirmed with the endoscopic ABC diagnosis since the serum ABC classification has several cutoff points and then a gray zone. Harmonization of serum ABC and endoscopic classification enables us to more precisely estimate the risk of gastric cancer. Moreover, higher risk groups and group that took eradication therapy for H. pylori should receive follow-up by a specialist.
