Abstract
A cytological, immunophenotypical and cytogenetical study of 136 chronic B-cell proliferations (93 CLL, 43 B-cell lymphomas) was led in order to precise diagnosis and to characterize and appreciate chromosomal rearrangements. In this series, mainly selected on blood lymphocytosis criteria, B-CLL were twice more frequent than small B-cell lymphomas. Probes used revealed cryptic abnormalities, which remained unknown by conventional cytogenetics (CC). The frequency of clonal abnormalities (CC and FISH) was 74.8% for this series, with 74.4% for lymphomas and 75.3% for CLL, mainly of Binet stage A (69 A, 13 B, 1 C, 10 unspecified). Proportion was 88.4% in A stages and 84.6% in B stages. In CLL, 13q14 cryptic deletions and translocations were widely majority, 14q32 translocations and trisomy 12 being predominant in lymphoma series. Interphase FISH study of non-clonal metaphasic abnormalities with locus-specific probes often revealed unrecognised clones.
