Cytogenetic analysis provides important information for diagnosis and prognosis in some tumors. But karyotype analysis can be difficult in some cases, because metaphase chromosomes are contracted. New techniques, such as fluorescence in situ hybridization and, more recently, spectral karyotyping, or SKY, based on the hybridization of 24 fluorescently… (More)
