No statistically significant correlations were identified between PMS2 expression loss and endoscopic tumor appearance (p = 0.662), tumor stage (p = 0.92), Ki-67 proliferation index (p = 1.00), CK7 expression loss (p = 1.00), CK20 expression loss (p = 0.797), CDX2 expression loss (p = 0.505), NLR (p = 0.271), or PLR (p = 0.079). Here, MKI67 is linked to neoplasm.
