The levels of IL-8 determined by ELISA in the serum of the patients were found to be statistically correlated with the level of the carcinoembryonic antigen (CEA) determined in the preoperative serum of the patients (P-value =0.003, R= 0.64), with tumor stage (P -value =0.01, R= 0.57), with distant metastasis (P-value =0.008) and with C-reactive protein (P -value =0.003, R= 0.64). The gene discussed is CXCL8; the disease is neoplasm.
