摘要
目的研究伴11p15/NUP98重排急性白血病的临床特点。方法运用常规染色体核型分析检测伴11p15异常的急性白血病患者,应用NUP98双色探针进行FISH验证,观察其临床特点和治疗效果。结果 598例初发AL中检出6例11p15异常,男1例,女5例,中位年龄39岁;分别为M5 3例,M2、M4和ALL各1例;经FISH验证均累及NUP98基因;患者中位生存期9个月。结论伴11p15异常的AL常累及NUP98基因,主要发生于女性,中位年龄偏低,多见于AML;临床表现以贫血、血小板少、白细胞高为主;伴11p15/NUP98重排的急性白血病对常规化疗反应差,预后不良,对异基因造血干细胞移植效果欠佳。
Objective To observe the clinical features and therapeutic effect of 11p15/NUP98 rearrange-ments in acute leukemia. Methods A total of 598 newly diagnosed acute leukemia patients were detected by con-ventional cytogenetics analysis and fluorescence in situ hybridization（FISH）with the NUP98 double color probe,and the clinical data were analyzed retrospectively in the patients with 11p15/NUP98 abnormality. Results Sixcases with 11p15/NUP98 rearrangement were found with a median age of 39 years old,one patient is male,the oth-ers are females. Three patients had acute monocytic leukemia（M5）,one patient had acute monocytic leukemia（M2）,one patient had acute monocytic leukemia（M4）,and one patient had acute lymphoblastic leukemia. 11p15/NUP98 abnormality was detectable in all the patients. The median survival in all the patients was 9 months. Conclusions Acute leukaemia with 11p15 abnormality frequently involves NUP98 gene and mainly occurrs in women.Patients with lower median age mainly developed in acute monocytic leukemia. The major clinical manifestationsare anemia,low platelets and hyperleukocytosis. Acute leukemia with 11p15/NUP98 rearrangement is poorly re-sponsive to routine chemotherapies and to allogeneic hematopoietic stem cell transplantation,and thus has poorprognosis.
