AGC-like EGCs predominate in the distal part of the stomach, while EGC-like AGCs predominate in the proximal part. When evaluating the depth of a gastric cancer, care should be taken not to underestimate measurements in proximal gastric cancers since they tend to be poorly-differentiated adenocarcinomas, in Lauren¡¯s diffuse type, and invade deeper than their endoscopic appearance might suggest.
