Comparative genomic hybridisation identifies two variants of smoldering multiple myeloma.
Two variants of smoldering multiple myeloma (SMM) have been recognised: (i) an evolving type, characterised by a progressive increase in the M-protein size and short time to progression to overt multiple myeloma (MM) and (ii) a non-evolving type, with a long-lasting, stable M-protein and longer time to progression. Comparative genomic hybridisation (CGH) analyses in both subtypes of SMM (seven evolving and eight non-evolving SMM) were performed. Evolving SMM showed cytogenetic changes consistent with those found in de novo symptomatic MM (1q gains, chromosome 13 deletions) while the non-evolving variant showed no 1q gains and deletions were uncommon.
