DPP4 and colorectal carcinoma: Hence, we compared the immune cell profile, including levels of lymphocyte, neutrophil, platelet (PLT), monocyte, albumin and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR) and prognostic nutritional index (PNI) in pre-operative and post-operative blood between CRC patients with and without DPP4-inhibitor treatment.
