We report a case of acute myeloid leukaemia (AML), FAB classification M2, associated with tetrasomy 8. This chromosomal aberration was detected using conventional cytogenetics and flourescent in-situ hybridization (FISH). Using FISH, the pre-treatment cells with tetrasomy 8 were disomic for chromosome 7. A small number of tetrasomy 8 cells were found post-treatment, but these were tetrasomic for chromosome 7. The significance of this is considered, and the literature regarding tetrasomy 8 in acute myeloid leukaemia is reviewed.
我们报告一例急性髓系白血病(AML),FAB分类为M2,伴有8号染色体四体。使用传统细胞遗传学和荧光原位杂交(FISH)检测到这种染色体畸变。使用FISH技术,发现预处理时带有8号染色体四体的细胞7号染色体为二体。治疗后发现少量8号染色体四体细胞,但这些细胞7号染色体为四体。我们探讨了这一现象的意义,并回顾了有关急性髓系白血病中8号染色体四体的文献。
