NST is becoming a widely accepted method for allogeneic HSCT. Much experience has been gained, and the biology, indications and limitations are becoming clearer. Nonmyeloablative conditioning allows consistent engraftment of allografts from matched related, unrelated, and even partially matched donors. ⋯ Identification of tumor antigens will lead the way to ex-vivo generation and expansion of tumor specific cytotoxic T-lymphocytes to be used as potent immunotherapy without the hazards of GVHD. Allogeneic transplantation is rapidly changing from administration of supralethal doses of chemotherapy and radiation, trying to physically eliminate the 'last tumor cell', to the more subtle and tolerated sophisticated immunotherapy. This effort will focus on specific induction of HVG tolerance followed by induction of tumor-specific GVT effect to cure the underlying malignancy.
