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.
【摘要】 目的 探討自體造血干細胞移植(autologous hematopoietic stem cell transplantation,auto-HSCT)治療侵襲性NK/T細胞淋巴瘤的療效。 方法 對我科2005年1月16日收治的1例侵襲性NK/T細胞淋巴瘤患者的造血干細胞移植和隨訪資料進行回顧性分析,并復習國內外相關文獻。 結果 患者為37歲女性,診斷結外鼻型NK/T細胞淋巴瘤,系統性,經CHOAP和ICE方案化學療法、手術、局部放射治療控制病情良好后,采集自體骨髓造血干細胞,行auto-HSCT,預處理方案為全身放射治療+ECy;移植+29 d造血功能即順利重建;移植后密切隨訪,患者一直處于完全緩解,至今已存活67個月。 結論 auto-HSCT治療侵襲性NK/T細胞淋巴瘤療效肯定、可靠。【Abstract】 Objective To explore the therapeutic effect of autologous hematopoietic stem cell transplantation (auto-HSCT) on aggressive NK/T lymphoma. Methods The clinical data of one patient with aggressive NK/T lymphoma diagnosed in January 2005 were retrospectively analyzed, and the relevant domestic literatures were analyzed. Results This thirty-seven-year-old female patient had good disease control after undergoing chemotherapy with CHOAP and ICE regimens, surgery, and locoregional radiotherapy. After that, she had been collected enough bone marrow-derived hematopoietic stem cells, then underwent auto-HSCT with these cells. The conditioning regimen was TBI plus ECy. On the +29th day after transplantation,the hematopoietic reconstruction was successful. During the follow-up period, the patient was in complete remission status all along and her disease-free survival (DFS) was 67 months. Conclusion Auto-HSCT is effective on aggressive NK/T lymphoma.
【摘要】 目的 探討對自體造血干細胞移植(autologous hematopoietic stem cell transplantation,auto-HSCT)后復發的非霍奇金淋巴瘤患者再進行異基因造血干細胞移植(allogeneic hematopoietic stem cell transplantation,allo-HSCT)治療的臨床療效。 方法 收集2000年1月-2010年12月難治性惡性淋巴瘤采用auto-HSCT后復發患者11例,病程27個月~6.5年。所有患者在auto-HSCT前均為復發難治性病例,auto-HSCT后,完全緩解8例,部分緩解3例,自體移植后中位復發時間15個月,患者復發后采用異基因親緣造血干細胞移植,人類白細胞抗原(human leukocyte antigen,HLA)全相合(6/6)6例,5/6相合3例,4/6相合2例;性別相同6例,性別不同5例。預處理方案為FBC方案,即氟達拉濱30 mg/m2 1~5 d,白消安12~14 mg/kg分4 d口服,環磷酰胺120 mg/kg分2 d使用。移植物均為外周血造血干細胞加骨髓。移植物抗宿主病(graft-versus-host disease,GVHD)的預防:HLA全相合采用環孢素+短程甲氨蝶呤+嗎替麥考酚酯,不全相合采用抗胸腺細胞球蛋白+環孢素+短程甲氨蝶呤+嗎替麥考酚酯。 結果 11例患者全部獲得造血重建,急性GVHD發生6例(54.55%),其中Ⅰ度、Ⅱ度4例,Ⅲ度、Ⅳ度各1例;1例Ⅳ度GVHD因合并感染死亡,5例均得到有效控制;發生慢性GVHD 7例(63.64%),其中有2例急性GVHD轉為慢性,4例局限型,3例廣泛型。隨訪8個月~9年,有4例分別于移植后8、15、21、34個月疾病復發,另外6例仍生存。 結論 allo-HSCT對于auto-HSCT后復發的非霍奇金淋巴瘤患者仍是一種有效的挽救性治療手段。【Abstract】 Objective To explore the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) on relapsing non-Hodgkin′s lymphoma after autologous stem cell transplantation (auto-HSCT). Methods The clinical data of 11 patients with recurrent non-Hodgkin′s lymphoma after auto-HSCT from January 2000 to December 2010 were collected, including nine males and 2 females with the median age of 39 years (13-48 years old), and the median duration of the disease was 3 years (27 months-6.5 years). All patients were relapsed or refractory cases. After auto-HSCT, complete remission was found in 8 and partial remission was in 3. The recurrence median time after auto-HSCT was 15 months. The patients underwent allo-HSCT after the recurrence of the disease. In the 11 patients, human leukocyte antigen (HLA) full matched (6/6) in 6, 5/6 matched in 3, and 4/6 matched in 2; the same gender in 6 and different gender in 5. FBC conditioning regimen: fludarabine 30 mg/m2 for 1-5 days, BU 12-14 mg/kg in 4 days of oral, CY 120 mg/kg in 2 days. Grafts are peripheral blood stem cells plus bone marrow. Prevention of graft-versus-host disease (GVHD): HLA full-matched by CsA+short-term MTX+MMF and mismatched by ATG+CsA+short-term MTX+MMF. Results All of the 11 patients received hematopoietic reconstruction, acute GVHD occurred in 6 cases (54.55%), including degree Ⅰ plus Ⅱ in 4, degree Ⅲ in 1 and degree Ⅳ in 1. One patient died of infection due to degree Ⅳ GVHD, and the rest had been effectively controlled. Chronic GVHD occurred in 7 patients (63.64%); limited type was in 4 in and extensive type was in 3. During the follow-up period of 8 months-9 years, 4 patients relapsed 8, 15, 21, and 34 months after transplantation, and the other 6 patients was still alive. Conclusion Allo-HSCT is effective on relapsing non-Hodgkin′s lymphoma after auto-HSCT.
