Abstract

CD15 (Lewis X/Lex) is a fucosyl (3-fucosly-N-acetyl-lactosamine) moiety found on membrane proteins of various cancer cells. These include renal cancer, prostate and bladder cancers, acute leukemias, hepatocellular carcinoma, breast cancer and melanoma. The antigen plays an espe-cially significant role in renal cell carcinoma. Its high expression serves as a good prognostic marker for patients and high hopes are related to its use in the immunotherapy of the tumor. The biological role of CD15 is the interaction with E-, L- and P-selectins (adhesion molecules) and al-lowing for the adhesion with the endothelial cells. In this way, cancer cells start to interact with the endothelium of blood vessels and consequently move out from the blood flow to the sur-rounding tissues. The blockage of antigen’s function results in reduced metastatic potential. Moreover, the molecule may be a therapeutic target against cancer in monoclonal antibod-ies-based therapies. CD15s is a sialyl derivative of CD15, that possess its own unique characteris-tics. Unlike high expression of CD15, which is a prognostic factor in Hodgkin lymphoma, CD15s relate to poor prognosis for the patients. Due to the high abundance in cancer cells, CD15 is con-sidered as a marker of Cancer Stem Cells. This review presents a comprehensive description of the role of CD15 and CD15s in cancer development and metastasis and overviews the clinical appli-cations of the anti-CD15 therapy.
