A 69-year-old man was diagnosed with chronic myelogenous leukemia (CML) and treated with dasatinib. After two years on dasatinib, the patient achieved complete molecular response, but dasatinib treatment was discontinued due to exacerbation of pleural effusion. Nilotinib and imatinib were started but stopped due to an increase in pleural effusion. Thoracentesis was performed and he was diagnosed with human herpesvirus 8-unrelated primary effusion lymphoma (PEL)-like lymphoma. Complex chromosomal abnormality, including BCL6 rearrangement, was found on chromosome analysis. To the best of our knowledge, this is the first report of PEL-like lymphoma following tyrosine kinase inhibitor treatment for CML.
一名69岁男性被诊断为慢性粒细胞白血病(CML),并接受达沙替尼治疗。使用达沙替尼两年后,患者达到完全分子反应,但由于胸腔积液加重而停用达沙替尼。随后开始使用尼洛替尼和伊马替尼,但因胸腔积液增加而停药。进行了胸腔穿刺术,他被诊断为人疱疹病毒8无关的原发性渗出性淋巴瘤(PEL)样淋巴瘤。染色体分析发现了包括BCL6重排在内的复杂染色体异常。据我们所知,这是酪氨酸激酶抑制剂治疗CML后发生PEL样淋巴瘤的首例报告。
