摘  要:目的探讨多重荧光原位杂交(m u ltip lex fluorescence in s itu hybrid ization,M-F ISH)在多发性骨髓瘤(m u ltip le m ye lom a,MM)复杂核型异常(com p lex chrom osom a l aberrations,CCA s)检测中的价值。方法联合应用常规细胞遗传学(conven tiona l cytogenetics,CC)方法及M-F ISH分析2例伴有复杂核型的MM患者。结果M-F ISH证实了MM原有的异常染色体+5,+7,+9,-13,+15,de l(6)(q16q26),add(2)(p25),der(4)t(4;?)(p11;?),add(22)(q11),并确定了add(2)(p25),der(4)t(4;?)(p11;?),add(22)(q11)的具体来源;同时也发现了CC分析未能发现或不能识别的der(6)t(6;17)(q?;?),der(7)t(1;7)(?;q21)×2,de l(9)(q21),der(9)t(1;9)(?;q21),de l(16p12),充分显示了M-F ISH的优越性。结论M-F ISH对于检测MM的CCA s具有优势,是精确分析染色体核型不可缺少的技术。Objective To explore the value of multiplex fluorescence in situ hybridization (M-FISH) in the detection of the complex chromosomal aberrations (CCAs) in multiple myeloma (MM). Methods Two MM patients with CCAs were analyzed by combining the conventional eytogeneties (CC) and M-FISH. Results M-FISH confirmed the aberrations which were previously detected by CC, +5, + 7, + 9, + 13, + 15, del ( 6 ) (q 16q 26 ), add ( 2 ) ( p 25 ), der (4) t (4; ? ) (p 11 ; ? ), add(22 ) (q11); and also found the specific source of add(2) (p25),der(4)t(4;?) (p11;?),add(22) (q11); detected der(6)t(6; 17) (q?; ?) ,der(7)t(1 ;7) (? ;q21) × 2,del (9) (q21) ,der (9)t(1; 9) (? ;q21) ,del (16p12) ,which were undetected or unidentified by CC analysis. Conclusions M-FISH has proved to be useful in characterization of the CCAs in MM, and it is an essential method to refine the karyotype analysis.
