唯一与特定染色体异常相关的骨髓增生性疾病是慢性髓性白血病,它与t(9;22)(q34;q11.2)或这种异常的变体有关。del(13)(q12 q14)与骨髓纤维化相关; t(5;12)(q33;p13)与嗜酸性粒细胞增多相关; del(20 q11)、+8和+9与真性红细胞增多症相关,但这些异常可在各种恶性血液病中观察到。骨髓增生性疾病中最常见的染色体异常按频率顺序为t(9;22)(q34;q11.2)、-Y、+8、+9、-7、del(20)(q11 q13)、del(13)(q12 q14)、del(5)(q13 q33)和del(12)(p12)。新的荧光标记DNA技术可用于骨髓增生性疾病,以研究不足的骨髓或血液标本,并监测已知染色体异常患者的疾病状态,但它们并不比传统的染色体研究更敏感。
The only myeloproliferative disorder associated with any specific chromosome anomaly is chronic myeloid leukemia, which is linked with t(9;22)(q34;q11.2) or a variant of this anomaly. An association exists for del(13)(q12q14) and myelofibrosis; t(5;12)(q33;p13) and eosinophilia; and del(20q11), +8, and +9 and polycythemia vera, but these anomalies can be seen in various hematologic malignancies. The most common chromosomal anomalies among myeloproliferative disorders in order of frequency are t(9;22)(q34;q11.2), -Y, +8, +9, -7, del(20)(q11q13), del(13)(q12q14), del(5)(q13q33), and del(12)(p12). New fluorescent-labeled DNA techniques are useful for myeloproliferative disorders to study inadequate bone marrow or blood specimens and to monitor disease status among patients with known chromosome anomalies, but they are not more sensitive than conventional chromosome studies.
