OBJECTIVES: I. Determine the maximum tolerated dose and dose limiting toxicity of radioimmunotherapy using high dose yttrium Y 90 humanized anti-CD22 monoclonal antibody LL2 (Y90 MOAB hLL2) followed by autologous peripheral blood stem cell transplantation in patients with B cell lymphomas or Waldenstrom's macroglobulinemia. II. Determine the organ and tumor dosimetry for comparison to clinical measurement of toxicity and antitumor responses in these patients. III. Determine magnitude and duration of human anti-humanized LL2 antibody (HAhLL2) or anti-DOTA response in these patients. IV. Evaluate the extent and duration of antitumor response to this regimen in these patients.
