The incidence of esophageal adenocarcinoma has increased dramatically over the past 20 years. The causes for this change in incidence and the genetic defects that underlie tumorigenesis are unknown. We performed loss of heterozygosity (LOH) studies in esophageal adenocarcinomas in an effort to map the location of tumor suppressor genes involved in the initiation or progression of this cancer. A genome-wide search for LOH was undertaken using microsatellite repeat polymorphisms and a panel of 27 tumor and matched normal DNAs. This is the first report of an allelotype analysis of esophageal adenocarcinomas. We observed frequent loss of sequences on the short arm of chromosome 17 in the region of the TP53 gene. We also identified a region on 4q lost in more than half of the tumors investigated. The high rate of LOH for 4q sequences speaks to the involvement of an as yet unidentified tumor suppressor gene in esophageal adenocarcinoma tumorigenesis.
