Cdx2 Information for Pathologists
Homeobox gene that encodes a nuclear transcription factor critical for intestinal embryonic development; relatively specific for intestinal epithelium (but see positive staining below). Terminology Also called caudal-related homeobox gene 2, caudal type homeobox transcription factor 2. Homologue of Drosophila melanogaster homeobox gene-caudal. Uses by pathologists
Common Uses By Pathologists:
Fairly specific marker of GI origin for adenocarcinomas, but also stains selected adenocarcinomas of other sites indicated below (Am J Surg Pathol 2003;27:303); can use to determine origin of metastatic adenocarcinoma as part of panel (Arch Pathol Lab Med 2007;131:1561). Distinguish primary and secondary colorectal adenocarcinomas (Arch Pathol Lab Med 2005;129:920). Distinguish primary bladder adenocarcinoma (CDX2-, villin-) from colorectal carcinoma extending / metastatic to bladder (CDX2+, villin+, Mod Pathol 2005;18:1217). Distinguish mucinous bronchioloalveolar adenocarcinoma (CDX2-) from metastatic mucinous colorectal adenocarcinoma (CDX2+, Am J Clin Pathol 2004;122:421). Microscopic (histologic) images
