摘要
目的评价自体造血干细胞移植(ASCT)治疗多发性骨髓瘤(MM)的疗效及其对预后的影响。方法回顾性分析2004年5月至2011年8月苏州大学附属第一医院血液科接受ASCT治疗的27例MM患者的临床资料,通过与同期经诱导化疗达良好部分缓解(VGPR)或以上疗效后巩固化疗的28例患者进行比较,分析ASCT对缓解程度、无进展生存(PFS)和总生存(0s)时间的影响以及MM患者的相关预后因素。结果所有患者移植后造血均顺利重建,无移植相关死亡。移植后完全缓解(CR)率由移植前的25.9%(7/27)提高到70.4%(19/27)(P〈0.01)。ASCT组、非ASCT组的预计5年PFS率分别为56.2%(未达中位PFS时间)和24.9%(中位PFS时间为29个月)(P〈0.05)。ASCT组、非ASCT组预计5年0S率分别为52.2%(未达中位0s时间)和33.1%(中位0S时间为60个月)(P〉0.05)。ASCT组患者相关预后因素分析发现移植后是否接受维持/巩固治疗与PFS(P=0.010)及OS(P=0.008)密切相关;接受以硼替佐米为主的方案诱导治疗,缓解后早期行自体移植,并接受维持治疗的患者PFS时间延长(P=0.010)。结论ASCT可以进一步提高患者的CR率,延长PFS,并可能会延长OS。新型靶向药物加入移植前后的诱导及巩固/维持治疗可优化ASCT,对改善MM患者的预后具有重要意义。
Objective To evaluate the efficacy and prognostic factors of autologous hematopoietic stem cell transplantation (ASCT) in multiple myeloma (MM) patients. Methods Retrospective analysis was performed in 27 MM patients undergoing ASCT at our hospital from May 2004 to August 2011. After comparing with 28 patients achieving very good partial response (VGPR) or better outcome and not undergoing ASCT, the impact on the extent of response, progression-free survival (PFS) and overall survival (OS) as well as related prognostic factors of MM patients were analyzed. Results All patients successfully underwent hematopoietic reconstruction without transplantation-related mortalityl The complete remission (CR) rate of ASCT group increased from 25.9% (7/27) at pre-ASCT to 70. 4% (19/27) at post-ASCT ( P 〈 0. 01 ). The estimated 5-year rate of progression-free survival was 56. 2% ( median not reached) in the ASCT group and 24. 9% (median 29 months) in the non-ASCT group (P 〈0. 05). The 5-year probability of overall survival was 52. 2% (median not reached) in the ASCT group and 33.1% (median 60 months) in the non-ASCT group (P 〉 0. 05 ). Univariate analysis in ASCT group demonstrated that maintenance/ consolidation therapy was associated with PFS ( P = 0. 010 ) and OS ( P = 0. 008 ). Patients on induction therapy containing boretizomib and early ASCT maintenance therapy all survived,without disease progression until final follow-up (P =0. 010). Conclusions ASCT can further increase the CR rate, prolong PFS and probably OS. The incorporation of novel agents into induction, consolidation and maintenance phases hasoptimized the anti-myeloma activity of ASCT and may be important for improved long-term outcomes.
