A therapeutic cancer vaccine consisting of autologous dendritic cells (DCs) fused with autologous tumor cells with potential immunostimulatory and antineoplastic activities. Autologous dendritic cell-tumor fusion vaccine is generated in vitro by mixing DCs and irradiated tumor cells harvested from individual patients and treating them with polyethylene glycol (PEG) to produce DC-tumor cell fusion hybrid cells. Upon administration, autologous dendritic cell-tumor fusion vaccine may elicit antitumor humoral and cellular immune responses.
