A prognostic impact of interleukin 32 (IL-32) as an immune marker in patients with bladder cancer

Abstract

Background. Urinary bladder cancer is a prevalent global health concern. IL-32 is a cytokine that promotes inflammation and has been shown in multiple studies to suppress the development of cancer cells and trigger cell death in different types of cancer cells. Materials and methods. Expression of 32 interleukins was determined using an immunohistochemistry technique, which uses analysis of the exact concentrations and locations of specific compounds in tissues. This is done by using antibodies, antibodies that react with the target protein (in this case IL-32), then identifying the sites where the active protein is located. The study included 114 diagnosed bladder cancer samples and 10 healthy controls. Results. By analyzing the expression of IL-32 using IHC technology on both bladder tissue from cancer patients and healthy bladder tissue that was considered a control, the results of evaluating IL-32 levels in bladder tissue from cancer patients showed a high level. Conclusion. High levels of IL-32 indicate disease progression or a poor outcome, while low levels can indicate an improvement or a good outcome. This is consistent with the fundamental aim of this study: the possibility of using IL-32 as a diagnostic or prognostic marker for disease progression and outcome prediction in cancer patients.
