Clinical significance of cytogenetics and interphase fluorescence in situ hybridization analysis in newly diagnosed multiple myeloma in Taiwan.
BACKGROUND The incidence of multiple myeloma (MM) is lower in Asia than in Western countries. However, it is not known whether cytogenetic abnormalities (CA) characteristic of MM in Asia differ from those documented in the West. PATIENTS AND METHODS We analyzed CA by conventional cytogenetics (CG) and/or fluorescence in situ hybridization (FISH), assessed their clinical significance in 150 Ch...
متن کاملCytogenetics of multiple myeloma.
Great studies of multiple myeloma (MM) strongly suggested that specific chromosomal changes are of prognostic significance in patients with MM1. We have performed cytogenetic analysis and recently fluorescent in situ hybridization (FISH) on 43 cases of MM. Clonal chromosomal changes were present in 24 (56%) cases. Hyperdiploid karyotype was found in 12 (50%) cases, hypodiploid in 8 (33%) cases,...
متن کاملThe value of fluorescence in situ hybridization for the detection of 11q in multiple myeloma.
BACKGROUND AND OBJECTIVES A large number of chromosomal abnormalities have been detected in multiple myeloma (MM). The most frequent are chromosome 13q deletions and translocations affecting the immunoglobulin heavy chain gene (IGH). Recent studies using comparative genomic hybridization (CGH) have shown that gains of 11q represent one of the most frequent genomic changes in MM. However CGH is ...
متن کاملValidation of interphase fluorescence in situ hybridization (iFISH) for multiple myeloma using CD138 positive cells
BACKGROUND Multiple myeloma is a plasma cell neoplasm with acquired genetic abnormalities of clinical and prognostic importance. Multiple myeloma differs from other hematologic malignancies due to a high fraction of low proliferating malignant plasma cells and the paucity of plasma cells in bone marrow aspiration samples, making cytogenetic analysis a challenge. An abnormal karyotype is found i...
متن کاملMultiple myeloma: high incidence of chromosomal aneuploidy as detected by interphase fluorescence in situ hybridization.
Because metaphase cytogenetic studies in multiple myeloma (MM) are hampered by a low proliferative activity of myeloma cells in vitro, interphase cytogenetics by means of fluorescence in situ hybridization (FISH) should improve the detection of chromosomal abnormalities in MM. We therefore investigated chromosomal aneuploidy in 36 patients with MM using interphase FISH and alpha-satellite DNA p...
