A univariate analysis showed that high preoperative PLR (P = 0.002, χ2 = 9.542) and CRP (P = 0.009, χ2 = 6.899), location (P = 0.031, χ2 = 4.627), maximum tumor diameter (P < 0.001, χ2 = 33.482), physician (P = 0.012, χ2 = 6.347) and number of tumors (P = 0.048, χ2 = 3.912) were significantly related to the histological type of colorectal polyps. The gene discussed is CRP; the disease is neoplasm.
