目的  增加對治療相關性繼發白血病的認識。 方法  報道非霍奇金淋巴瘤治療后2年繼發急性髓細胞白血病M6型1例,結合文獻討論治療相關性白血病的發病機制、治療、預后。 結果  1例73歲非霍奇金淋巴瘤患者接受R(Rituxmab,利妥昔單抗)-CHOP環磷酰胺+多柔比星+長春新堿+潑尼松方案規律化學治療。治療結束24+個月后,經骨髓涂片及細胞免疫分型診斷為急性髓細胞白血病M6型,染色體檢查為:44~48,XY,del(5)(q12q33),-8,-10,der(12)t(4;12)(q11-q12;p13),其一般情況急劇惡化并死亡。 結論  治療相關性白血病的發生可能與烷化劑等化療藥物使用和免疫受損等有關,利妥昔單抗導致第二腫瘤的發生暫時不能除外。治療相關性白血病常伴有復雜染色體核型,其病情發展迅速,治療效果差,生存期明顯縮短。
Objective  To improve the understanding of secondary therapy-related leukemia. Methods  The clinical data of one patient with non-Hodgkin lymphoma which transformed into acute myeloid leukemia M6 2 years after chemotherapy were studied. We discussed the pathogenesis, treatment and prognosis of therapy-related leukemia with literature review. Results  A 73-year-old patient diagnosed to have non-Hodgkin’s lymphoma accepted R-CHOP chemotherapy.Two years after the treatment, the disease finally developed into acute myeloid leukemia M6 confirmed by cytogenetics, bone marrow morphology and flowcytometry analysis. The chromosome analysis demonstrated complex karyotypes as 44-48, XY, del (5) (q12q33), -8, -10, der (12) t (4; 12) (q11-q12; p13). His general status deteriorated rapidly and soon after the patient died. Conclusions  Occurrence of therapy-related leukemia may be due to the administration of alkylating agents, topoisomerase inhibitors and damage of immune function. Therapy-related leukemia often occurs with complex karyotypes and progresses rapidly with poor treatment response.
