ABSTRACT
<p><b>OBJECTIVE</b>To investigate the prevlance of 1q21 amplification in patients with multiple myeloma (MM) and its correlation with the progression and prognosis of the disease.</p><p><b>METHODS</b>1q21 amplification was detected in 48 patients with MM using cytoplasmic light chain immunofluorescence with fluorescence in situ hybridization analysis (cIg-FISH) and interphase fluorescence in situ hybridization (I-FISH) analysis combined with CD138 immunomagnetic cell sorting (MACS).</p><p><b>RESULTS</b>1q21 amplification (≥ 3 red signals) was detected in 26/48(54.2%) cases by cIg-FISH and 31/48 (64.6%) cases by I-FISH combined with CD138 MACS. There was a good consistency between the two methods (P>0.05). The mortality of patients with 1q21 amplification was significantly higher than those without (P< 0.05). No significant difference was detected in terms of sex, age, Durie-Salmon stage, subgroup and international staging system (ISS) stage between patients with 1q21 amplification and those without (P>0.05).</p><p><b>CONCLUSION</b>The frequency of 1q21 amplification in MM is high. There was also an association between the amplification and poor prognosis. cIg-FISH is consistent with CD138 MACS combined with I-FISH.</p>
