Sphingosine-1-Phosphate (S1P) is a bioactive phospholipid molecule that regulates multiple signaling pathways through its interaction with sphingosine-1-phosphate receptors (S1PRs). In cancer tissues, S1P is not only associated with the survival of cancer cells, but also related to the angiogenesis, inflammatory responses, and immune evasion in the tumor microenvironment (TME). Various inhibitors of the S1P kinase have shown significant anti-tumor effects in pre-clinical studies by directly inhibiting tumor growth and metastasis, and enhancing the therapeutic potential of both chemotherapy and immunotherapy. Nevertheless, the complex and pleiotropic nature of the S1P signaling pathway presents considerable challenges for the development of targeted therapeutic strategies. This paper reviews the biological functions and research progress of S1P and its related pathways in cancer, offering novel insights and potential directions for cancer therapy.
