Summary
Brief summary (as posted)
RATIONALE: Radiolabeled monoclonal antibodies can find cancer cells and carry cancer-killing substances to them without harming normal cells. This may be effective treatment for leukemia. PURPOSE: This phase I trial is studying the best dose of yttrium Y 90-labeled monoclonal antibody BU-12 in treating patients with advanced relapsed or refractory acute lymphoblastic leukemia or chronic lymphocytic leukemia.
