Therefore, these aberrations have clinical and biological significance. T(3;12)(q26;p13), which is a recurrent chromosomal aberration observed in myeloid malignancies, is typically associated with dysplasia of megakaryocytes, multilineage involvement, short duration of any blastic phase, and extremely poor prognosis. We have identified a recurrent reciprocal translocation between chromosomes 3 and 12 with different breakpoint at bands 3q21 in the malignant cells from a 28-year-old man. The patient was initially diagnosed as having Ph+ CML in the chronic phase. The t(3;12)(q21;p13) translocation occurred 4 years after the patient was first diagnosed with CML while undergoing tyrosine kinase inhibitor therapy. We confirmed the t(3;12)(q21;p13) translocation via fluorescence in situ hybridization assay by using whole-chromosome paint probes for chromosomes 3 and 12. Our findings demonstrate that, similar to other recurrent translocations involving 3q26 such as t(3;3) and t(3;21), the t(3;12)(q21;p13) translocation is implicated not only in myelodysplastic syndrome and acute myeloid leukemia but also in the progression of CML. These findings extend the disease spectrum of this cytogenetic aberration.展开更多

文摘目的:探讨酪氨酸激酶抑制剂(tyrosine kinase inhibitor,TKI)联合地西他滨、高三尖杉酯碱、干扰素方案在慢性髓性白血病急变期(blast phase chronic myeloid leukemia,CML-BP)患者缓解后维持治疗的疗效。方法:回顾性分析2015年6月至2021年12月就诊于郑州大学附属肿瘤医院经诱导治疗首次获得主要血液学反应的CML-BP患者的临床资料,采用log-rank检验比较TKI联合地西他滨、高三尖杉酯碱、干扰素组(n=18)与TKI联合传统化疗组(n=10)维持治疗患者的中位无事件生存时间、缓解持续时间和总生存时间。结果:共纳入28例患者,中位年龄46(24-58)岁。Kaplan-Meier生存分析显示,TKI联合地西他滨、高三尖杉酯碱、干扰素组较TKI联合传统化疗组的无事件中位生存时间(7.4 vs 4.3个月,P=0.043,HR=0.44,95%CI:0.17-1.14)、持续缓解中位时间(16.1 vs 6.6个月,P=0.005,HR=0.32,95%CI:0.11-0.89)及总生存中位时间(34.3 vs 13.5个月,P=0.006,HR=0.29,95%CI:0.10-0.82)均显著延长。结论:对于CML-BP且获得缓解的患者,TKI联合地西他滨、高三尖杉酯碱、干扰素方案较TKI联合传统化疗方案维持治疗可显著延长患者生存。
