All data, with the exception of the peripheral blood lymphocytes (PBL)% CD19⁺, have been reported previously in Billadeau et al.11

Bone marrow (BM) percent (%) based on Southern blot analysis of marrow DNA probed with a J(H) probe.

PBL% CD19⁺ is the percent of CD19⁺ cells detected by flow cytometry and calculated as described in Materials and Methods.

All values are initial diagnosis samples, except numbers in parentheses, which represent samples analyzed after 2 months of therapy.
