OUTLINE: This is a dose-escalation, multicenter study. Patients receive filgrastim (G-CSF) subcutaneously (SC) with or without chemotherapy on days -28 to -14 and peripheral blood stem cell (PBSC) collection on days -14 to -11. If an adequate number of CD34+ cells are not harvested, bone marrow may be collected. Patients receive pretherapy imaging with indium In 111 monoclonal antibody MN-14 IV for up to 40 minutes on day -7 followed by whole body imaging on days -7 to 0. Patients receive yttrium Y 90 monoclonal antibody MN-14 (Y90 MOAB MN-14) IV for up to 40 minutes on day 0. PBSC or bone marrow is reinfused on days 6 to 14, depending on antibody clearance. Patients receive G-CSF SC or IV until blood counts recover. Cohorts of 3-6 patients receive escalating doses of Y90 MOAB MN-14 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Patients are followed weekly for 2 months, monthly for 6 months, and then every 6 months for 5 years.
