Dendritic Cell Vaccines Presenting Autologous Tumor Antigens from Self-renewing Cancer Cells in Metastatic Renal Cell Carcinoma

Metastatic renal cell cancer is typically resistant to chemotherapy but does respond to vascular endothelial growth factor receptor signal transduction inhibition and to a variety of immunotherapies, including interleukin (IL)-2 and monoclonal antibodies that inhibit immune checkpoints. Enhanced immune recognition of tumor antigens may improve clinical outcomes. The objective of this study was to investigate the effects of a patient-specific approach utilizing autologous dendritic cell vaccines and self-renewing autologous tumor cells in patients with metastatic renal cell carcinoma.
