Abstract:
:Although reports have suggested the incomplete type of intestinal metaplasia (IM) had a close correlation with carcinoma, considerable data showed no apparent relationship between the particular type of IM and the intestinal type carcinoma. The purpose of this study was to establish a novel classification of IM using brain-type glycogen phosphorylase (BGP) from a carcinogenetic viewpoint. The only isoform expressed in gastric cancer was BGP using polymerase chain reaction analysis. We studied 136 specimens with gastric carcinoma and the adjacent IM using specific anti-BGP antibody with its correlation to subtypes of IM, proliferating cell nuclear antigen-labeling index, and various oncogene products. Brain-type glycogen phosphorylase was expressed in 80.5% of the intestinal type and 18.8% of the diffuse type of carcinoma and in 87.5% and 41.6% in the generative zone of IM adjacent to cancer foci, respectively, whereas no reactivity was observed in the normal gastric mucosa. The proportion of the positivity in the cancer and IM was significantly greater in the intestinal-type carcinoma than in the diffuse type. The expression of BGP in the generative cells of IM had no significant correlation with the conventional type of IM. Intestinal metaplasias with BGP expression were significantly higher in a proliferating state than in those without BGP, and some of them that were coexpressed accumulated p53 in the generative cells. The relationship between IM with BGP in the generative cells and intestinal-type carcinoma was apparently closer than the conventional subtype of IM and gastric cancer. Intestinal-type carcinoma might arise from some of these proliferating cells with BGP.
