Their results showed that CDX2 expression loss was related to the right side of the colon [3–6, 11, 14, 16, 17, 19, 20, 22, 23, 25–29], dMMR [3–6, 11, 14, 16–18, 20–23, 25, 28, 29], poorly differentiated (high grade) CRC [3–5, 11, 14, 15, 17–19, 21, 23, 25] and mucinous CRC [3, 5, 6, 29]. Here, CDX2 is linked to colorectal carcinoma.
