Abstract

The Polymerase Chain Reaction (PCR) was used to evaluate minimal residual disease in 21 Ph+ CML patients at various intervals after allogeneic bone-marrow transplantation (AMBT) by amplification of bcr-abl cDNA. All patients were cytogenetically Ph- at the moment of molecular analysis. Of these 76% were PCR negative, 24% positive for bcr-abl transcripts. 100% of the Cyclosporine A/Methotrexate treated patients (7/7) were negative. Severe chronic GvHD was twice as frequent in PCR positive patients (60%) than in negative ones (31%). The only patient who relapsed during follow up was PCR positive. The two longest survivors were PCR negative. These data are still insufficient for assessing the predictive value of PCR analysis in CML.
