OBJECTIVES: I. Evaluate the efficiency of tumor cell removal by immunomagnetic technique in patients with B cell malignancies. II. Determine toxicity of mobilized peripheral blood stem cell (PBSC) components of enriched CD34+ and depleted B cells in this patient population. III. Compare recovery with the use of this treatment regimen to the use of unmanipulated PBSC or CD34+ PBSC components in this patient population.
