摘  要:目的 研究荧光原位杂交(fluorescence in situ hybridization,FISH)技术在骨髓增生异常综合征(myelodysplastic syndrome,MDS)的诊断、细胞遗传学及预后评估中的重要意义.方法 对2010年12月-2015年4月山西医科大学第二医院收集的113例MDS患者进行FISH检测,分析细胞遗传学在MDS患者中的表达和意义.结果 ①113例MDS患者依据WHO(2008)分型诊断标准,难治性血细胞减少伴单系发育异常(refractory cytopenia with unipa-rental dysplasia,RCUD)占16.0%(18/113)、难治性贫血伴环状铁幼粒细胞(refractory anemia with ringed sideroblasts,RARS)占2.6%(3/118)、难治性血细胞减少伴多系发育异常(refractory cytopenia with multiple dysplasia,RCMD)占28.3%(32/113)、难治性贫血伴原始细胞增多(re-fractory anemia with excess blasts,RAEB)占44.2%(50/113)、MDS-未分类(MDS-U)占8.0%(9/113)、5q-综合征占0.9%(1/113).44.2%(50/113)的MDS患者具有异常染色体,依次为+8(23.9%)、-5/5q-(15.9%)、-7/7q-(14.2%)、20q-(9.7%)、-Y(2.7%),复杂核型占8.0%(9/113);其中仅伴染色体数目异常者24(21.2%)例,伴染色体结构异常者17(15.0%)例,同时伴有数目和结构异常者13(11.5%)例;MDS各亚型患者中,RCUD组染色体异常率最高,约占50%(9/18),后依次为RAEB组异常率占48.0%(24/50)、RCMD组异常率占43.8%(14/32)、RARS组异常率占33.3%(1/3);根据修订的国际预后积分系统(IPSS-R)进行危险度分层,非常低危组占0.9%(1/113),低危组占23.0%(26/113),中危组占31.9%(36/113),高危组占31.9%(36/113),非常高危组占12.4%(14/113);②单体核型组与非单体核型组相比,有低的血小板计数(P=0.039).结论 FISH检测对MDS的诊断、预后分析、指导治疗具有重要价值;将是否合并的单体核型列入预后分层中,可能对提高预后分层准确性有意义.Objective To study the importance of fluorescence in situ hybridization ( FISH ) in the diagnosis , cytogenetics and prognosis evaluation of myelodysplastic syndrome ' s ( MDS ) . Methods Retrospectively analyzed the expression and the significance of cytogenetics in 113 MDS patients with FISH in the Second Hospital Shanxi Medical University from December 2010 to April 2015 . Results ①Ac-cording to WHO ( 2008 ) classification and diagnosis of MDS , the 113 patients included 16 . 0%( 18/113 ) Refractory cytopenia with unilineage dyspiasia ( RCUD ) , 2 . 6% ( 3/118 ) refractory anemia with ringed sideroblasts ( RARS ) , 28 . 3% ( 32/113 ) refractory cytopenia with mutilineage dysplasia ( RC-MD ) , 44 . 2%( 50/113 ) refractory anemia with excess blast ( RAEB ) , 8 . 0% ( 9/113 ) myelodys-plastic syndrome , unclassified ( MDS-U ) , and 0 . 9% ( 1/113 ) MDS associated with isolated del ( 5 q ) . The MDS patients with abnormal cytogenetics accounted for 44 . 2%( 50/113 ) , and order is +8(23. 9%), -5/5q-(15. 9%), -7/7q-(14. 2%), 20q-(9. 7%), -Y(2. 7%), and complex karyotype 8 . 0%( 9/113 ) . In all the cases , 24 ( 21 . 2%) patients have abnormal number of chromo-somes 17 ( 15 . 0%) patients have abnormal structure of chromosomes , 13 ( 11 . 5%) patients exhibit both number and structural abnormalities in chromosomes . Among all subsets of MDS patients , RCUD has the highest cytogenetic abnormal rate ( ~50%, 9/18 ) , the abnormal rate in RAEB group for 48 . 0%( 24/50 ) , RCMD for 43 . 8%( 4/32 ) , RARS for 33 . 3 ( 1/3 ) . According to the Revised Internation-al Prognostic Scoring System ( IPSS-R ) , very low subgroup accounting for 0 . 9% ( 1/113 ) , low sub-group accounting for 23 . 0% ( 26/113 ) , intermediate subgroup accounting for 31 . 9% ( 36/113 ) , high subgroup accounting for 31 . 9%( 36/113 ) , and very high subgroup accounting for 12 . 4%( 14/113 ) . ②The plat
