We recently assessed the expression and prognostic relevance of six immunohistochemical markers (Ki67, p53, biglycan (BGN), receptor for hyaluronan-mediated motility (RHAMM), and insulin-like growth factor II mRNA binding protein 3 (IMP3)) in urachal adenocarcinomas. Here, TP53 is linked to bladder urachal adenocarcinoma.
