SCREEN FOR RISK FOR GASTRIC ADENOCARCINOMA
专利汇可以提供SCREEN FOR RISK FOR GASTRIC ADENOCARCINOMA专利检索，专利查询，专利分析的服务。并且It has been determined that a specific metaplastic lineage that contains immunoreactivity for a trefoil polypeptide, spasmolytic peptide, is associated with and gives rise to the vast majority of human adenocarcinomas. The identification of this Spasmolytic Polypeptide Expressing Metaplasia (SPEM) is a major factor for grading of biopsies of the stomach to assess risk for gastric cancer. It also forms the basis of a method for serological screening for those at risk for gastric cancer. In a preferred embodiment, antibodies to spasmolytic peptide (hSP) are used in immunostaining of biopsies of gastric tissue obtained by endoscopy for grading biopsies. Those patients having these cells, characterized by a morphology more typical of a type of cell present normally in the intestine and not stomach, Brunner's gland cells, are at risk of developing adenocarcinoma. Since these cells express hSP, antibodies or nucleic acid probes hybridizing to mRNA encoding hSP, can be used for rapid detection of the cells in tissue biopsies. The antibodies can also be used in serological tests for screening and following patients at risk for gastric cancer. In combination with evidence of previous or present infection with H. pylori, the test are predictive of the likelihood of developing adenocarcinoma.，下面是SCREEN FOR RISK FOR GASTRIC ADENOCARCINOMA专利的具体信息内容。
