Therapy-related myelodysplastic syndrome (t-MDS) after autologous stem cell transplantation (ASCT) is a rare complication with no curative option. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) may be considered for eligible patients and has been understudied in t-MDS. We report 47 consecutive patients with t-MDS after an ASCT who underwent allo-HSCT with a median age of 58 years (range, 30 to 71 years) at transplantation and a median follow-up of 22 months (range, 0.7 to 107). The median overall survival (OS) was 6.9 months (95% confidence interval [CI], 0 to 19 months). OS rates were 45% (29% to 60%) and 30% (15% to 45%) at 1 and 3 years after transplantation, respectively. On univariate analysis, prior therapy for t-MDS before allo-HSCT (P = .02) and mismatched donors (P = .004) were associated with poor OS. Three-year nonrelapse mortality (NRM) and relapse rates were 44% (25% to 63%) and 41% (22% to 61%), respectively. Mismatched donors (P < .001) were associated with higher NRM and a high-risk MDS (P = .008) with a higher relapse risk. On multivariate analysis, HLA mismatch was associated with higher NRM (hazard ratio, 6.21; 95% CI, 1.63 to 23.62; P = .007). In conclusion, our results suggest that one third of the patients who develop t-MDS after an ASCT for lymphoma are cured after an allo-HSCT. The use of mismatched donors with standard graft-versus-host disease prophylaxis should be avoided in such an indication for allo-HSCT. It will be worthwhile to see if the implementation of cyclophosphamide post-transplantation will improve the outcome with mismatched donors.

自体移植淋巴瘤后同种异体干细胞移植在治疗相关的骨髓增生异常中的作用:法语国家骨髓移植和细胞治疗学会的回顾性研究。

自体干细胞移植(ASCT)后与治疗相关的骨髓增生异常综合症(t-MDS)是一种罕见的并发症,没有治疗选择。异基因造血干细胞移植(allo-HSCT)可考虑用于符合条件的患者,并且已在t-MDS中进行了研究。我们报告了47例ASCT术后连续t-MDS患者,他们接受了all-HSCT移植时的中位年龄为58岁(范围为30至71岁),中位随访时间为22个月(范围为0.7至107岁)。 。中位总生存期(OS)为6.9个月(95%置信区间[CI],0到19个月)。移植后1年和3年的OS率分别为45%(29%至60%)和30%(15%至45%)。单因素分析表明,在同种-HSCT治疗前先行t-MDS治疗(P = .02)和供体不匹配(P = .004)与OS差有关。三年非复发死亡率(NRM)和复发率分别为44%(25%至63%)和41%(22%至61%)。不匹配的供体(P <.001)与较高的NRM和高风险的MDS(P = .008)相关,且具有较高的复发风险。在多变量分析中,HLA不匹配与较高的NRM相关(危险比,6.21; 95%CI,1.63至23.62; P = .007)。总之,我们的结果表明,针对异基因HSCT的淋巴瘤患者接受ASCT治疗后发展为t-MDS的患者中有三分之一可以治愈。在同种异体造血干细胞移植的适应症中,应避免使用不匹配的供体和标准的移植物抗宿主疾病预防措施。值得一提的是,移植后环磷酰胺的实施是否会改善供体不匹配的结果。分别。不匹配的供体(P <.001)与较高的NRM和高风险的MDS(P = .008)相关,且具有较高的复发风险。在多变量分析中,HLA不匹配与较高的NRM相关(危险比,6.21; 95%CI,1.63至23.62; P = .007)。总之,我们的结果表明,针对异基因HSCT的淋巴瘤患者接受ASCT治疗后发展为t-MDS的患者中有三分之一可以治愈。在同种异体造血干细胞移植的适应症中,应避免使用不匹配的供体和标准的移植物抗宿主疾病预防措施。值得一提的是,移植后环磷酰胺的实施是否会改善供体不匹配的结果。分别。不匹配的供体(P <.001)与较高的NRM和高风险的MDS(P = .008)相关,且具有较高的复发风险。在多变量分析中,HLA不匹配与较高的NRM相关(危险比,6.21; 95%CI,1.63至23.62; P = .007)。总之,我们的结果表明,针对异基因HSCT的淋巴瘤患者接受ASCT治疗后发展为t-MDS的患者中有三分之一可以治愈。在同种异体造血干细胞移植的适应症中,应避免使用不匹配的供体和标准的移植物抗宿主疾病预防措施。值得一提的是,移植后环磷酰胺的实施是否会改善供体不匹配的结果。HLA不匹配与较高的NRM相关(危险比,6.21; 95%CI,1.63至23.62; P = .007)。总之,我们的结果表明,针对异基因HSCT的淋巴瘤患者接受ASCT治疗后发展为t-MDS的患者中有三分之一可以治愈。在同种异体造血干细胞移植的适应症中,应避免使用不匹配的供体和标准的移植物抗宿主疾病预防措施。值得一提的是,移植后环磷酰胺的实施是否会改善供体不匹配的结果。HLA不匹配与较高的NRM相关(危险比,6.21; 95%CI,1.63至23.62; P = .007)。总之,我们的结果表明,针对异基因HSCT的淋巴瘤患者接受ASCT治疗后发展为t-MDS的患者中有三分之一可以治愈。在同种异体造血干细胞移植的适应症中,应避免使用不匹配的供体和标准的移植物抗宿主疾病预防措施。值得一提的是,移植后环磷酰胺的实施是否会改善供体不匹配的结果。在同种异体造血干细胞移植的适应症中,应避免使用不匹配的供体和标准的移植物抗宿主疾病预防措施。值得一提的是,移植后环磷酰胺的实施是否会改善供体不匹配的结果。在同种异体造血干细胞移植的适应症中,应避免使用不匹配的供体和标准的移植物抗宿主疾病预防措施。值得一提的是,移植后环磷酰胺的实施是否会改善供体不匹配的结果。
