Klinefelter syndrome (KS) is a sex chromosome disorder and has been reported to be associated with increased risk for malignancies. We report a 22-year-old male patient who was diagnosed to have chronic myeloid leukemia in chronic phase. Bone marrow cytogenetic examination revealed karyotype 47, XXY, t (9; 22)(q34, q11) suggestive of KS with presence of Philadelphia chromosome. The patient was treated with oral imatinib mesylate (400 mg/day). Complete hematological response was achieved after 2 months of therapy. The bcr-abl/abl transcript percentage measured from peripheral blood at baseline, 1 and 2 years after imatinib were 97%, 1.99%, 0.007%, respectively. He remains in complete hematological and major molecular remission after 2 years of continued imatinib therapy.
克兰费尔特综合征（KS）是一种性染色体疾病，据报道其患恶性肿瘤的风险增加。我们报告一名22岁男性患者，其被诊断为慢性期慢性髓性白血病。骨髓细胞遗传学检查显示核型为47, XXY，t（9；22）（q34，q11），提示患有KS并存在费城染色体。该患者接受口服甲磺酸伊马替尼（400毫克/天）治疗。治疗2个月后达到完全血液学缓解。在伊马替尼治疗前、治疗1年和2年后，从外周血测得的bcr-abl/abl转录本百分比分别为97%、1.99%、0.007%。在持续伊马替尼治疗2年后，他仍处于完全血液学缓解和主要分子缓解状态。
