(A) H&E-stained Barrett's esophagus biopsy specimen showing high-grade dysplasia at the end of follow-up after PDT. (B) Immunohistochemistry for Ki-67 with the Mib-1 antibody showing increased proliferation in epithelial cells. (C) p53 protein overexpression assessed by immunohistochemistry with the DO-7 antibody shows intense staining for p53 in virtually all nuclei. (Original magnification 10×.)
