BACKGROUND Sensitive techniques for detection of minimal residual disease (MRD) at degrees of one leukaemic cell per 10(3)-10(6) cells (10(-3)-10(-6)) during follow-up of children with acute lymphoblastic leukaemia (ALL) can provide insight into the effectiveness of cytotoxic treatment. However, it is not yet clear how information on MRD can be applied to(More)
A large series of 202 childhood precursor-B cell acute lymphoblastic leukemia (ALL) patients was analyzed by Southern blotting (SB) for cross-lineage rearrangements and/or deletions in the T cell receptor TCRB, TCRG and TCRD loci. In 93% (187/201) of the precursor-B-ALL patients one or more genes were rearranged and/or deleted. TCRB gene rearrangements were(More)
