Afterwards, CRCs were assigned into two groups regarding their CDX2 expression (CDX2 groups): CRCs that showed a CRC expression that was on the 10th percentile and below (range: 0–60% of tumour cells; n = 102, 10%) were categorised as CDX2-low/absent and CRCs with a CDX2 expression above the 10th percentile (61–100% tumour cells; n = 901, 90%) were categorised as CDX2- high. This evidence concerns the gene CDX2 and neoplasm.
