We used molecular biology techniques to study the genetic events associated
with the development of human esophageal cancer. Point mutations of the p53
tumor suppressor gene were detected in one of 10 squamous cell and one of
14 adenocarcinomas of the esophagus, a frequency that implicates this gene
in tumorigenesis. However, the finding of p53 mutations in Barrett's
epithelium adjacent to adenocarcinomas may have clinical implications for
p53 as a premalignant marker for esophageal cancer.
