Dendritic Cell Cancer Vaccines for Treatment of Colon Cancer

Abstract Despite advances in treatment modalities, colorectal cancer (CRC) still accounts for about half a million deaths yearly worldwide. The majority of metastatic CRC are unresectable, and of those who undergo resection, few are cured. Advances in chemotherapy and targeted therapy have improved survival, but options remain limited, making the case for incorporating novel modalities in CRC treatment paradigm. Our improved understanding of the tumor immune microenvironment had led to the development of novel immunotherapeutic agents that have been tested in clinical trials such as cancer vaccines. Cancer vaccines are designed to activate the effector immune cells in order to generate an immune response against tumors. Dendritic cell vaccines offer potential benefits for CRC patients but requires further evaluation. We reviewed the role of dendritic cells in the colorectal tumor microenvironment and dendritic cancer vaccine studies in colorectal cancer.
