  • Title: Gene alterations in intestinal metaplasia and gastric cancer.
    Author: Tahara E, Kuniyasu H, Yasui W, Yokozaki H.
    Journal: Eur J Gastroenterol Hepatol; 1994 Dec; 6 Suppl 1():S97-102. PubMed ID: 7735945.
    Abstract:
    PURPOSE: To review genetic alterations in precancerous lesions and adenocarcinoma of the stomach. RESULTS: Telomere reduction, tpr-met oncogenic rearrangement, overexpression of cripto, p53 mutations, adenomatous polyposis coli gene mutations and K-ras mutations, which are frequently associated with the well differentiated or intestinal type of stomach cancer, were found in intestinal metaplasia and adenoma of the stomach. CONCLUSIONS: Among these genetic alterations, reduction of telomere repeat arrays might be the initial step in the genetic instability of stomach carcinogenesis. Some of the well differentiated type stomach cancers may develop by an accumulation of multiple gene changes similar to those of colorectal cancer.
