A cell-based cancer vaccine consisting of autologous dendritic cells (DCs) pulsed with mesothelioma tumor lysate with potential immunostimulating and antineoplastic activities. Upon administration, mesothelioma tumor lysate-pulsed autologous dendritic cell vaccine may stimulate the host immune system to mount a specific cytotoxic T lymphocyte (CTL) response against mesothelioma tumor cells, resulting in tumor cell lysis.
