摘  要:目的探讨22号染色体三体(+22)在诊断inv(16)急性髓系白血病(AML)中的价值。方法采用红、绿荧光直接标记的双色断裂点分离的基因探针CBFβ对18例存在+22克隆异常的AML患者进行间期荧光原位杂交(FISH)检测,并与R显带常规细胞遗传学(CC)检测结果进行比较分析。应用多重荧光原位杂交(M—FISH)技术检测同时伴有+22和inv(16)的AML患者。结果18例存在+22的AML患者中,CC分析未发现inv(16)阳性,而FISH检测发现11例inv(16)阳性、1例del(16)(q22)。这11例阳性患者中,9例CC分析为单纯+22异常,1例伴有+8,1例患者为del(16)(q22),而FISH检测为inv(16)。M—FISH检测4例同时伴有+22和inv(16)的患者,除+22外,未发现其他异常。结论+22是预测inv(16)AML的重要标志,具有潜在的诊断inv(16)AML的价值。Objective To explore the value of trisomy 22 ( + 22) in the diagnosis of inv(16) acute myeloid leukemia (AML). Methods Interphase fluorescence in situ hybridization (FISH) was performed in 18 AML patients with + 22. The probe was two-color break apart probe for CBFβ with SpectrumRed on the centromerie side and SpectrumGreen on the telomeric side. The FISH results were compared with that of Rbanding conventional cytogenetics (CC). Multiplex FISH (M-FISH) was used to analyze the relationship of + 22 and inv(16). Results CC revealed inv(16) in none of the 18 AML with + 22, but FISH revealed inv (16) in 11 of them and del(16) (q22) in one. As CC results, 9 of the 11 cases were sole + 22, one complicated with trisomy 8, and one del(16) (q22). Four patients with +22 and inv(16) were analyzed by M- FISH and revealed + 22 only. Conclusion + 22 can be regarded as an important marker for the diagnosis of inv(16) AML.
