摘  要:目的探讨恶性血液病伴有t(3;3)(q21;q26)或inv(3)(q21q26)患者临床及实验室特点。方法骨髓细胞24h短期培养后制备染色体标本,R技术显带后进行核型分析;链霉卵白素-碱性磷酸酶(Streptavidin-AKP,SAP)法检测小巨核细胞;流式细胞仪间接免疫荧光法检测白细胞表面抗原,综合分析临床和实验室资料。结果9例染色体核型为t(3;3)(q21;q26)或inv(3)(q21q26)的患者均存在明显的病态造血,对化学治疗反应差,其中1例行异基因造血干细胞移植后短期复发。结论3q21q26综合征可见于各型恶性血液病,具有独特的临床特征,预后极差。Objective To investigate the chnical and laboratory characteristics of various hematopoietic malignant patients with t(3;3)(q21;q26) or inv(3) (q21q26). Methods Bone marrow samples were collected at presentation, prepared by short-time unstimulated culture and R-binding, and karyotyped by conventional cytogenetical assay (CCA) ; megalokaryocytes were detected by Streptavidin-AKP(SAP) ; immunotype of the leukemia cells was tested by flow cytometric anylysis of surface antigens (FACS). Results All of the 9 hematopoietic malignant patients with t(3;3) (q21 ;q26) or inv(3) (q21q26) manifested myelodysplasia and poor treatment response, One of them relapsed shortly after allogenic hemotopoietic stem cell transplantation (allo-HSCT). Conclusion Patients with 3q21q26 rearrangement can be found in various hematopoietic malignances and demonstrate an unique entity. These patients show poor treatment response and have extremely poor prognosis.
