自体造血干细胞移植对多发性骨髓瘤患者预后的影响

目的 探讨自体造血干细胞移植(ASCT)在多发性骨髓瘤(MM)治疗中的地位以及对预后的影响.方法 回顾分析1998年10月至2007年2月接受ASCT治疗的28例MM患者(A组)的临床和随访资料,并与同期未行ASCT的MM患者,包括接近完全缓解(nCR)或以上缓解的23例(B组)和仅获得部分缓解(PR)的25例(C组)患者进行比较.分析 ASCT对缓解程度的影响并采用Kaplan-Meier法比较3组患者的缓解持续时间(DOR)、疾病进展时间(TTP)和生存(OS)时间.结果 移植前未达到nCR的8例患者[7例PR和1例轻微缓解(MR)]移植后均达到nCR或以上缓解(3例CR,5例nCR),A组完全缓解(CR)率由移植前的10.7%(3例)提高到42.9%(12例).A组中位DOR(33个月)较B组(17个月)和C组(18个月)延长,差异有统计学意义;A组中位TTP(45个月)较C组(28个月)延长,差异有统计学意义,但与B组(43个月)无明显差异;中位随访时间为30(4～79)个月,A组和B组OS时间较C组长,但随访结束时未显示出差异有统计学意义.结论 ASCT可进一步增强患者的缓解程度,延长患者的DOR和TTP,并可能延长OS时间,改善生存质量;ASCT对TTP的延长得益于更好程度的缓解,因此对其他治疗不能达到很好缓解的MM患者可以通过ASCT改善预后.

The impact of autologous stem cell transplantation on the prognosis in multiple myeloma

OBJECTIVE: To evaluate the efficacy of autologous stem cell transplantation (ASCT) in the treatment of multiple myeloma (MM) and its impact on the prognosis of MM. METHODS: Retrospective analysis was performed in 28 patients with MM (group A) treated with ASCT in our hospital from October 1998 to February 2007, compared with those not received ASCT in the same time period including 23 patients with near complete response (nCR) or better (group B) and 25 patients with partial response (PR) (group C). The duration of response (DOR), time to progression (TTP) and overall survival (OS) were compared by Kaplan-Meier method in the 3 groups. RESULTS: Eight patients without nCR or better (7 in PR and 1 in MR) after ASCT achieved CR (2 cases) and nCR (5 cases). Complete response (CR) rate was 10.7% (3 cases) and 42.9% (12 cases) before and after ASCT respectively in group A. DOR was 33 months for group A, 17 months for group B and 18 months for group C, and TTP was 45, 43 and 28 months respectively. After a median follow-up of 30 months, patients in group A and in group B had a trenel of longer OS than in group C although there was no statistically significant difference. CONCLUSIONS: ASCT can further enhance the response, prolong the DOR and TTP and probably OS, and therefore improve the quality of life in MM. MM patients not achieved good response by non-ASCT therapy may benefit from ASCT.
