In a prospective study of 42 patients with myelofibrosis with myeloid metaplasia (MMM), peripheral blood (PB) and bone marrow (BM) interphase cytogenetics and PB CD34 enumeration were performed concomitantly with BM karyotype analysis. Interphase cytogenetics was performed with a panel of fluorescence in situ hybridization (FISH) probes that were capable of detecting most of the known recurrent cytogenetic lesions in MMM. There was a close concordance in the results of interphase cytogenetics between PB and BM, regardless of the PB CD34 count. In general, FISH-detectable abnormalities were also detected by BM karyotype. Although complementary, interphase cytogenetics may not always provide the necessary karyotypic information in MMM.
