CDX2
CDX2 is a commonly used immunostain in pathology. It is a nuclear stain.

- Colorectal adenocarcinoma ~ 90% of cases.[2]
Sometimes positive
- Stomach adenocarcinoma ~20-30% of cases.[2]
- Esophageal adenocarcinoma ~20-30% of cases.[2]
- Ovarian mucinous adenocarcinoma[1] ~20-30% of cases.[2]
- Endometrioid endometrial adenocarcinoma ~20-30% of cases.[2]
Negative or positive
- Yolk sac tumour (8 +ve of 20 cases[3]).
- Small bowel adenocarcinoma +ve/-ve (~43% +ve in series of 189 cases[4]).
Negative
