Objective: To explore the impact of the expression levels of interleukin-17 (IL-17) in blood and urine on the prediction of bladder cancer. Methods: The study population consisted of bladder cancer patients diagnosed at our hospital between March 2022 and October 2023, included as the experimental group, and a healthy control group consisting of individuals undergoing physical examinations during the same period. The blood and urine IL-17 levels between the two groups were compared and analyzed. Results: A total of 31 patients were included in the experimental group and 34 in the control group. The blood and urine IL-17 levels in the experimental group were both significantly higher than those in the control group (P<0.05 for both). Additionally, a higher difference in IL-17 levels was observed in serum compared to urine samples. Conclusion: Interleukin-17 is an effective immunomarker for predicting the occurrence and progression of bladder cancer.
