Few patients with nonfavorable risk (NFR) acute leukemia and myeloid dysplasia syndrome (AL/MDS) undergo allogeneic transplantation (HCT). We assessed whether this could be improved by integrating HCT/leukemia care and the use of haploidentical donors. Of 256 consecutive patients aged <75 years who received initial therapy at our center for NFR AL/MDS from 2016 to 2021, 147 (57%) underwent planned HCT (70% for patients aged <60 years). In the logistic regression analysis, age (OR 1.50 per 10-year increment; P < .001) and race (Black vs White [OR 2.05; P = .023]) were significant factors for failure to receive HCT. Reasons for no HCT included comorbidities (37%), poor KPS, lack of caregiver support, refractory malignancy (19% each), and patient refusal (17%). Lack of donor or insurance were rarely cited (3% each). In older patients (≥60 years), comorbidities (49 vs 15%; P < .001) and KPS (25% vs 10%; P = .06) were more common, and lack of caregivers was less common (13% vs 30%; P = .031). In Black vs White patients, lack of caregivers (37% vs 11%; P = .002) was more frequent. The median time from initial treatment to HCT was 118 days and was similar for Black and White patients. Landmark analysis showed that HCT within 6 months of the initial treatment produced better survival. Multivariable analysis showed that HCT resulted in a significant survival benefit (HR 0.60; P = .020). With the above approach, most of the currently treated patients aged <75 years can access planned HCT. Black patients remain at greater risk of not receiving HCT.
在非不良风险(NFR)急性白血病和骨髓增生异常综合征(AL/MDS)的患者中,很少有接受异基因移植(HCT)的患者。我们评估了通过整合 HCT/白血病护理和使用半相合供体是否可以改善这种情况。在 2016 年至 2021 年期间,我们中心对 256 名年龄<75 岁的连续 NFR AL/MDS 患者进行了初始治疗,其中 147 名(57%)接受了计划 HCT(<60 岁患者的比例为 70%)。在逻辑回归分析中,年龄(每增加 10 岁,OR 1.50;P<0.001)和种族(黑人与白人[OR 2.05;P=0.023])是未接受 HCT 的显著因素。未进行 HCT 的原因包括合并症(37%)、较差的 KPS、缺乏护理人员支持、恶性肿瘤难治性(各占 19%)和患者拒绝(17%)。缺乏供体或保险很少被提及(各占 3%)。在年龄较大的患者(≥60 岁)中,合并症(49%比 15%;P<0.001)和 KPS(25%比 10%;P=0.06)更常见,而缺乏护理人员的情况较少(13%比 30%;P=0.031)。与白人患者相比,黑人患者的护理人员缺乏(37%比 11%;P=0.002)更为常见。从初始治疗到 HCT 的中位时间为 118 天,黑人和白人患者之间相似。 landmark 分析显示,初始治疗后 6 个月内进行 HCT 可获得更好的生存。多变量分析显示,HCT 可显著提高生存率(HR 0.60;P=0.020)。通过上述方法,目前大部分<75 岁的治疗患者都可以接受计划 HCT。黑人患者仍然面临不能接受 HCT 的更大风险。
