  • Title: Grading of gastric epithelial dysplasia. An interobserver study and analysis of diagnostic criteria.
    Author: Koktysz R, Zieliński KW, Kulig A.
    Journal: Pol J Pathol; 1997; 48(1):5-14. PubMed ID: 9200955.
    Abstract:
    One of the fundamental problems in the pathology of gastric epithelium is differentiation of reactive or regenerative proliferations, which are not precancerous from precancerous proliferations (i.e. dysplasia) and cancer. Diagnostic and interpretational difficulties, a need for a close cooperation between pathologists and clinicians and an attempt to more precisely assess gastric epithelial dysplasia prompted us to evaluate the usefulness of the current morphological criteria in the diagnosis and grading of gastric epithelial proliferations. The present study indicates that there are no sufficient grounds for grading of dysplasia, although the current morphological criteria permit establishment of a correct diagnosis. Therefore, the currently used three-grade classification of dysplasia may be successfully replaced with an easier two-grade classification or resigned totally.
