Since the establishment of methods to isolate genes encoding cytotoxic
T lymphocyte defined tumor antigens, several antigens have been ident
ified and characterized for suitability as target antigens for immunot
herapy. The development of innovative strategies to generate T cells t
argeting these antigens and lessons learned from clinical trials of ad
optive immunotherapy of viral diseases should facilitate the design of
clinical trials for specific adoptive immunotherapy of cancer.
