title: Allelotype of the adenoma-carcinoma sequence of the stomach.
abstract: In order to identify the significant allelic loss involving the gastric adenoma-carcinoma sequence, we used 49 genome-wide microsatellite markers in an allelotype study of 30 cases of stomach resections that harbored both adenomas and carcinomas. Frequent loss of heterozygosity was demonstrated on 12q (53.3%), 2p (50.0%), and 18p (50.0%) in adenomas and on 8q (80.0%), 2p (70.0%), 18p (66.7%), and 17p (61.9%) in carcinomas. Significant difference in the loss of heterozygosity rate between the adenoma and the carcinoma was noted on 17p. Our results suggested that the critical target of loss of heterozygosity in gastric adenomacarcinoma sequences may be the p53 gene on 17p.
