Association between new plasma inflammatory markers and risk of colorectal neoplasms in individuals over 50 years old.

OBJECTIVE(S):The prognostic value of systemic cytokine profiles and inflammatory markers in colorectal cancer were explored by several studies. We want to know more about inflammatory biomarkers in colorectal adenoma and early cancer. METHOD:The level of 38 inflammatory markers in the plasma of 112 adenoma patients, 72 Tis-T1 staging of colorectal carcinoma patients, 34 T2-T4 staging of colorectal carcinoma patients and 53 normal subjects were detected and compared. RESULT(S):Eight inflammatory biomarkers (Eotaxin, GCSF, IL-4, IL-5, IL-17E, MCP-1, TNF-α and VEGF-A) have higher plasma concentrations in colorectal adenoma and cancer patients compared with normal participants over 50 years old. CONCLUSION(S):Inflammatory markers may have the prognostic value for colorectal adenoma and early-stage carcinoma.
