TL;DR
This study compares a new method of stem cell transplant without freezing to the traditional method in newly diagnosed multiple myeloma patients.
Contribution
The study introduces a cryopreservation-free integrated autologous stem cell transplant model and evaluates its safety and efficacy.
Findings
The new model showed higher rates of very good partial or complete remission before transplant.
It had lower rates of severe mucositis and bacterial infections compared to the traditional method.
The new model showed similar overall survival and recurrence rates as the traditional method.
Abstract
探讨无冻存一体化自体造血干细胞移植模式在多发性骨髓瘤(MM)患者中的疗效和安全性。 纳入2020年7月31日至2022年12月31日在电子科技大学附属医院四川省人民医院接受自体造血干细胞移植的新诊断多发性骨髓瘤(NDMM)患者96例,对其临床资料进行回顾性分析。41例患者接受无冻存一体化移植模式(观察组),造血干细胞动员采集后冷藏于医用输血冰箱(4 °C)并立即启动美法仑预处理,预处理结束24 h后回输自体造血干细胞;55例患者接受传统移植模式(对照组),造血干细胞动员采集后液氮冷冻保存,择期启动移植流程。两组患者均采用G-CSF联合普乐沙福进行自体造血干细胞动员。 ①观察组移植前疾病状态为非常好的部分缓解(VGPR)及完全缓解(CR)患者占比显著高于对照组[82.9%(34/41)对60.0%(33/55),P=0.016]。②与对照组相比,观察组1级口腔黏膜炎的发生率较高(P<0.001),但2、3级口腔黏膜炎的发生率较低(P=0.004,P=0.048),两组均未发生≥4级口腔黏膜炎;观察组1级腹泻的发生率较高(P=0.002),3级腹泻的发生率较低(P=0.007),4级腹泻的发生率差异无统计学意义(P=0.506),两组均未发生5级腹泻。③观察组细菌感染发生率低于对照组(34.1%对65.5%,P=0.002),真菌感染(29.3%对31.4%,P=0.863)、病毒感染(4.88%对3.64%,P=0.831)发生率差异无统计学意义。④观察组与对照组粒细胞植入时间和血小板植入时间差异无统计学意义[10(8~20)d对11(8~17)d,P=0.501;13(10~21)d对15(10~20)d,P=0.245]。⑤移植后100 d前所有患者均未使用来那度胺治疗。移植后30 d,观察组CTL、NK、Th细胞计数低于对照组(P<0.001,P=0.049,P=0.002),NKT细胞计数高于对照组(P=0.024)。移植后100…
