Microsatellite alterations in phenotypically normal esophageal squamous epithelium and metaplasia-dysplasiaadenocarcinoma sequence

Abstract

The sequence of metaplasia-dysplasia-adenocarcinoma is associated with microsatellite alterations, including MSI and LOH. The MSI and LOH may be the early genetic events during esophageal carcinogenesis, and genetic alterations at the D3S1616, D5S346 and D3S123 loci may play a role in the progress of microsatellite alterations.
