Due to the low proliferative rate of tumor cells in the
early stage of MM, CC analysis of metaphase cells is
likely to miss detecting the primary genomic aberrations
in non-dividing tumor cells. Furthermore, some small
chromosomal rearrangements in MM may be cryptic to
chromosome banding analysis. Thus FISH, which is
effective for analysis of interphase nuclei and small
chromosomal aberrations, is recognized as the most
robust genetic test for characterizing the known cytogenetic abnormalities in MM. Nevertheless, integration
of data from the multiple genetic profiling techniques
including CC, FISH, RT-PCR, and gene mutation analysis, among others, would provide comprehensive information for better stratification of MM patients with
diagnostic and prognostic significance
