Summary
Brief summary (as posted)
RATIONALE: Monoclonal antibodies can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Radioactive monoclonal antibodies, such as yttrium Y 90 monoclonal antibody, can find cancer cells and either kill them or carry cancer-killing substances to them without harming normal cells. PURPOSE: This phase I trial is studying the side effects and best dose of a yttrium Y 90 monoclonal antibody and how much radiation is taken in by the organs in the body in treating patients with advanced leukemia or other hematologic disorder.
