摘要 目的研究8号染色体三体(+8)异常在慢性淋巴细胞白血病(chronic lymphocytic leukemia,CLL)患者中的发生率、临床特征及其预后价值。方法在常规核型分析的基础上,采用组合荧光探针,运用间期荧光原位杂交技术检测151例初诊CLL患者中+8的发生情况。结果151例患者中仅两例(1.3%)存在+8,阳性细胞率分别为8%、10%,两例患者的染色体核型分别为47,XY,+8[2]/49,XY,+14,+20,+21[2]/46,XY[16]和47,XX,+8[2]/46,xx[18]。结论+8异常在CLL群体中少见,其与预后关系暂不明确。 Objective To investigate the incidence of trisomy 8 in chronic lymphocytic leukemia (CI.I.) and its significance in prognosis. Methods A panel of probes and fluorescence in situ hybridization (FISH) were used to detect trisomy 8 in 151 CLL patients combined with chromosome karyotype analysis. Results There were 2 patients (1.3 % ) with trisomy 8 in the 151 CLL patients, and the number of trisomy 8 cells was 8% and 10% respectively. The karyotypes were 47,XY,+8[2]/49,XY,+14,+20,+21[2]/ 46,XY[16], and47,XX,+8[2]/46,XX[18], respectively. Conclusion Trisomy 8 was rare inCLL, and its significance in prognosis of CLL still remains unknown.
