摘要: A case of ANLL following a myelodysplastic syndrome, probably resulting from occupational exposure to ionizing irradiation, with two cytogenetically unrelated clones, hexasomy 8 and trisomy 11, was investigated by conventional cytogenetics FISH. Significant quantitative differences between data obtained metaphase interphase analysis the clone were observed. difference in sensitivity chemotherapy clones found: while markedly decreased response treatment, 11 remained unchanged.
