ABSTRACT: Aim
The change in the levels of peripheral inflammatory markers together with EGFR in relation to 5- fluorouracil (5-FU) therapy was evaluated for their prognostic significance in colorectal cancer (CRC) patients.Patients and methods
Expression levels of COX2, IL6, IL1?, EGFR, IL10, and TNF? were determined with quantitative real-time PCR (qPCR) in the peripheral blood of 90 CRC patients. The inflammatory response was correlated with patients' clinical features, disease-free survival (DFS), and overall survival (OS).Results
After 6 months of 5-FU therapy, increased inflammatory response was found to be associated with smoking, T3 or T4 tumors, performance status (PS) III, positive lymph nodes, distant metastasis, and gastrointestinal (GIT) toxicity. The combination of COX2 with interleukins in a predictive equation for DFS was significant in patients with over-expression of EGFR. DFS and OS rates were reduced in patients with increased COX2, IL6, IL10, and TNF? expression with 5-FU therapy. Significant hazard of disease progression was associated with smoking (HR=1.27, P=0.004), 5-FU induction of COX2, and IL6 expression (HR=1.35, P=0.001 and HR=1.27, P=0.004, respectively). Moreover, smoking, 5-FU induction of IL6, TNF?, and IL10 expression are found to be independent prognostic factors for OS (P=0.003, 0.003, 0.002, and 0.002, respectively).Conclusion
The peripheral effects of 5-FU therapy have shown a significant impact on the treatment outcome of CRC patients.
