Abstract:
Interleukin 17 (IL17) is a cytokine involved in immune regulation and has been increasingly recognized for its role in cancer progression. This systematic review aims to integrate data on IL17's role in various tumors to better understand its implications for cancer prognosis and treatment. The review included 105 studies (27.6% experimental and 72.4% clinical). Clinical studies involved 9266 patients: 31.2% males, 60.0% females, and 8.8% with undefined gender. IL17A and IL17 were the most studied subtypes (36.2% and 33.3%, respectively). Breast cancer (26.7%), colorectal carcinoma (13.3%), and hematologic malignancies (10.5%) were the most researched neoplasms. IL17A promoted tumor growth in breast cancer and correlated with poor outcomes in colorectal, breast, and lung cancers. IL17 also played a significant role in immune modulation in gliomas and other tumors. IL17A significantly influences tumor growth and prognosis across various cancers, with notable roles in immune modulation and poor outcomes in multiple cancer types.
