Abstract

Objectives The aim of the present study was to investigate the effect of treatment on IL-1, IL-6, IL-8 and neopterin levels in patients with non-muscle invasive bladder cancer (NMIBC). Methods Thirty patients with NMIBC and 30 age-matched controls were included in the study. Preoperative, postoperative first control (at two weeks after second transurethral resection of bladder tumor (TURBT)) and second control (at the end of intravesical immunotherapy) blood samples were analyzed by ELISA to determine IL-1, IL-6, IL-8 and neopterin levels. The mean cytokine levels of the patients were statistically compared as well as comparing the patients’ and controls’ levels. Results There were no statistically significant differences between the mean IL-1, IL-6, IL-8 and neopterin levels of the patient and control group before initial TURBT. In the patient group, there were no statistically significant differences in the IL-6 and IL-8 levels after both TURBT and intravesical BCG therapy. The mean of preoperative IL-1 and neopterin levels significantly decrease after TURBT (p<0.05=). However this reduction do not continue after intravesical BCG instillations. Conclusions The finding of this study showed that the IL-1, IL-6, IL-8 and neopterin levels of the patients with NMIBC were similar to the levels of healthy controls. The IL-1 and neopterin levels significantly decreased after TURBT. But this reductions did not continue after intravesical BCG instillation. These findings demonstrate that IL-1 and neopterin levels decrease after TURBT due to the reduction of tumor weight or tumor removal.
