Abstract

BACKGROUND
AND METHODS: The Gastrointestinal Pathology Study Group of the Korean Society of Pathologists developed a standardized pathology reporting format for gastric cancer in collaboration with the Korean Gastric Cancer Association. RESULTS: The diagnostic parameters are divided into two part: the standard part and the optional part. The standard part contains most of the items listed in the Japanese classification, the TNM classification by UICC, the WHO classification, and the Korean Gastric Cancer Association classification. Therefore, the standard part is adequate for routine surgical pathology service. We included detailed descriptions on each item.
CONCLUSIONS
The authors anticipate that this standardization can improve the diagnostic accuracy and decrease the discrepancies that occur in the pathologic diagnosis of gastric cancer. Furthermore, the standard format can encourage large scale multi-institutional collaborative studies.
