Tyrosine kinase inhibitor treated chronic myelogenous leukemia patients with monosomy 7 arising in Philadelphia chromosome negative (Ph-) cells tend to evolve into MDS/AML. However, monosomy 7 in Ph- cells can be a transient finding, and it is not an absolute indication of the emergence of a new myeloid malignancy.
酪氨酸激酶抑制剂治疗的慢性髓性白血病患者,若费城染色体阴性(Ph-)细胞中出现7号染色体单体,则往往会演变为骨髓增生异常综合征/急性髓系白血病。然而,Ph-细胞中的7号染色体单体可能是一个短暂的发现,并非新的髓系恶性肿瘤出现的绝对指征。
