Optimized multiplex IgH/ras PCR: a tool for quantitative monitoring of B-lymphoproliferative disorders.
The use of quantitative PCR is recommended to monitor the level of residual hematological malignancies. The proposed multiplex IgH/ras PCR uses a co-amplification of the clonal CDR3 rearrangement of the immunoglobulin heavy chain gene (IgH) as a disease marker and a segment of the Hras 1 gene containing codon 61 (ras) as a control gene. Serial dilutions of stored diagnostic DNAs are examined together in the same PCR at a sub-plateau phase and, after analysis by densitometry, the amount of CDR3 product is related to the ras product. An increase of this ratio at comparable amounts of DNA is viewed as an increase of malignant cells. This endpoint PCR quantifying approach appears to be applicable in monitoring B-lymphoproliferative disorders as was shown to be true in B-cell non-Hodgkin's lymphoma and may provide information on disease activity and treatment outcome.
