Fig. 2From: p53 immunostaining pattern is a useful surrogate marker for TP53 gene mutationsMucinous adenocarcinoma of the colon that experienced neo-adjuvant chemoradiation therapy but did not show any TP53 mutation. A Several strips or clusters of tumor cells are floating in the mucin pool (Hematoxylin & Eosin, × 10 objective lens). B TP53 overexpression pattern is noted (p53 immunohistochemistry, × 10 objective lens)Back to article page
