Systemic Interleukins' Profile in Early and Advanced Colorectal Cancer.

Tumor microenvironment (TME) is characterized by mutual interactions of the tumor, stromal and immune cells. Early and advanced colorectal tumors differ in structure and present altered serum cytokine levels. Mutual crosstalk among TME infiltrating cells may shift the balance into immune suppressive or pro-inflammatory, antitumor response this way influencing patients' prognosis.

Serum cytokine profile as a potential prognostic tool in colorectal cancer patients - one center study.

Aim: Comparison of 14 cytokines levels between a control group and prospectively enrolled CRC patients to confirm their significance in CRC development. We tested if a model based on 14 cytokines levels could predict prognosis in Caucasian CRC patients treated with 5-FU based chemotherapy.

Background: Novel prognostic tools in colorectal cancer (CRC) are necessary to optimize treatment, reduce toxicity and chemotherapy (CHT) costs.
