The data from the study suggested that the hepatoid type and the yolk sac tumor‐like type are derived from liver cell metaplasia and yolk sac cell metaplasia of common poorly differentiated medullary adenocarcinoma, respectively. The fetal gastrointestinal type seemed to be a result of the imitation of fetal gastrointestinal epithelium by common tubular adenocarcinoma. The hepatoid type was also the most common in the file of AFP‐producing gastric carcinoma. Unfortunately, most of the hepatoid types seemed to be highly malignant.","PeriodicalId":75413,"journal":{"name":"Acta pathologica japonica","volume":"43 11","pages":"654-61"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1440-1827.1993.tb02549.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18515979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, there was no significant difference in the mean sinusoidal radius or in the distribution of 1/(radius)4 values between the normal liver and the cirrhotic liver. Resistance changes of the lattice sinusoidal model, where resistance of each sinusoidal branch is proportional only to its length, were then studied. In the lattice model analysis, the resistance between the two endpoints becomes larger as the cycle rank of the network model decreases.

In situ hybridization of EBER-1 was applied to paraffin sections from 1848 carcinomas observed in 1795 cases and EBV involvement was detected based on uniform hybridization in carcinoma cells. Epstein-Barr virus was detected in 6.6% of lesions and 6.7% of cases. The rate of EBV involvement did not vary significantly for each city and there was no correlation with underlying gastric cancer mortality rates. Thus, geographic variation of gastric cancer rates within Japan cannot be explained in terms of EBV involvement. Epstein-Barr virus-related gastric carcinoma is one of the most common EBV-related tumors in Japan. The involvement of EBV was significantly more frequent among males than among females, mainly for cancers occurring in the upper and middle part of the stomach, and exhibited more variation by cell type among males.
