Current knowledge and key points. - This review summarizes the requirements of such therapies involving either activated lymphocytes, tumor-infiltrating lymphocytes or activated macrophages. It focuses more particularly on the promising approaches that represent antigen presenting cells such as macrophages and antigen-loaded dendritic cells in the development of safe and effective cancer vaccines. Future prospects and projects. - Standardized procedures for macrophages and dendritic cell generation, as well as preliminary results of clinical applications in patients with either prostate cancer or melanoma, are also discussed.
