title: Analysis of BCR/ABL abnormalities in mRNA from 20-year-old paraffin-embedded tissue for BCR/ABL rearrangement by polymerase chain reaction.
abstract: We studied whether it is possible to obtain sufficient mRNA from old paraffin-embedded samples of spleen and bone marrow for reverse transcription and polymerase chain reaction analysis. Spleen tissue from 6 subjects with chronic myelogenous leukemia was studied for rearrangement of BCR and ABL genes. Analysis was successful in 4 cases. These data indicate the feasibility of retrospective analysis of tissue samples of special interest by molecular techniques.
