Myelodysplastic/myeloproliferative overlap neoplasms (MDS/MPN) are rare hematological malignancies. We analyzed the outcomes of 75 patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) for MDS/MPN. Graft-versus-host disease (GvHD) prophylaxis included post-transplantation cyclophosphamide (PTCy) in 71% of patients, with 44 (59%) receiving a combination of anti-thymocyte globulin (ATG) and PTCy. The median follow-up was 44.4 months. Primary graft failure occurred in three patients (4%). The incidence of grade III-IV acute GvHD at day 100 was 13% (95% CI: 6-22). At 2 years, the incidence of moderate-severe chronic GvHD, non-relapse mortality (NRM), relapse, GvHD-free/relapse-free survival (GRFS), and overall survival (OS) was 31.7% (95% CI 20.7-43.2), 37.9% (26-49), 17.4% (95% CI: 10-27), 24.8% (95% CI: 15-36), and 51.6% (95% CI: 39-63), respectively. PTCy-based GvHD prophylaxis seemed to be associated with improved OS (HR: 0.5, 95% CI: 0.3-0.9, p = 0.03), NRM (HR: 0.4, 95% CI: 0.2-0.9, p = 0.03), and GRFS (HR: 0.5, 95% CI: 0.3-0.8, 0.009). On multivariable analysis, the use of the PTCy-containing regimen seemed to be associated with improved NRM (HR: 0.41; 95% CI: 0.2-0.8; p = 0.03), GRFS (HR: 0.47; 95% CI: 0.3-0.8; p = 0.009), and OS (HR: 0.49; 95% CI: 0.2-0.9; p = 0.03) without an increased risk of relapse.
骨髓增生异常/骨髓增殖性重叠肿瘤(MDS/MPN)是罕见的血液系统恶性肿瘤。我们分析了75例接受异基因造血干细胞移植(HSCT)治疗MDS/MPN患者的预后情况。移植物抗宿主病(GvHD)预防措施包括71%的患者使用移植后环磷酰胺(PTCy),其中44例(59%)接受了抗胸腺细胞球蛋白(ATG)与PTCy的联合治疗。中位随访时间为44.4个月。3例患者(4%)发生原发性移植失败。100天时III-IV级急性GvHD的发生率为13%(95%CI:6-22)。2年时,中重度慢性GvHD、非复发死亡率(NRM)、复发率、无GvHD/无复发生存率(GRFS)和总生存率(OS)分别为31.7%(95%CI 20.7-43.2)、37.9%(26-49)、17.4%(95%CI:10-27)、24.8%(95%CI:15-36)和51.6%(95%CI:39-63)。基于PTCy的GvHD预防似乎与OS改善(HR:0.5,95%CI:0.3-0.9,p = 0.03)、NRM改善(HR:0.4,95%CI:0.2-0.9,p = 0.03)和GRFS改善(HR:0.5,95%CI:0.3-0.8,p = 0.009)相关。多变量分析显示,使用含PTCy方案似乎与NRM改善(HR:0.41;95%CI:0.2-0.8;p = 0.03)、GRFS改善(HR:0.47;95%CI:0.3-0.8;p = 0.009)和OS改善(HR:0.49;95%CI:0.2-0.9;p = 0.03)相关,且复发风险未增加。
