Abstract:Background and Aim
Surveillance of non-dysplastic Barrett’s esophagus (BE) is recommended to identify progression to dysplasia; however, the most cost-effective strategy remains unclear. Mutation or aberrant expression of p53 has been associated with the development of dysplasia in BE. We sought to determine if surveillance intervals for BE could be stratified based on p53 expression.
Methods
A Markov model was developed for non-dysplastic BE. Patients with non-dysplastic BE (NDBE) underwent p53 immunohistoch… Show more
