 OUTLINE: After completion of induction or salvage chemotherapy, patients receive immunotherapy comprising anti-CD3 x anti-CD20-armed ATC IV weekly for 2 weeks. At least 1-3 weeks after the second infusion, patients receive high-dose chemotherapy and then undergo autologous peripheral blood stem cell transplantation. Patients then undergo leukapheresis for G-CSF-mobilized autologous T-cells.
