摘要
目的评价一线自体造血干细胞移植(ASCT)治疗初诊多发性骨髓瘤(MM)患者的疗效,分析其预后相关因素。方法对给予沙利度胺和(或)硼替佐米为基础的诱导化疗并获得部分反应以上疗效的60例初诊MM患者,进行一线ASCT治疗,分析其总生存(OS)和无进展生存(PFS),并探讨国际分期系统(ISS)分期、治疗反应、荧光原位杂交(FISH)检测细胞遗传学异常与患者预后的相关性。结果随访至2012年12月31日,中位随访36.8(12.0~102.5)个月。全组患者预期中位OS和PFS时间分别为未达到和86.5个月。60例患者移植后均获得≥非常好的部分反应(VGPR),其中34例(56.7%)为完全反应(CR)。获得CR者的PFS时间较获得VGPR者长(P=0.030),而3年预期0s率差异无统计学意义(P=0.942)。ISS分期不影响患者的PFS时间(P=0.445)和OS率(P=0.467)。单因素分析显示IgH重排、p53缺失、13q14缺失和1q21扩增等细胞遗传学异常均为与患者生存相关的不良预后因素。去除合并t(4;14)/t(14;16)或p53缺失患者,13q14缺失及1q21扩增与PFS和0s均无相关性。t(4;14)影响患者的PFS而非0s。p53缺失的患者预后差,特别是合并其他细胞遗传学异常者,中位PFS和OS时间分别仅17和31个月。结论新药联合一线ASCT治疗初诊MM患者,可获得高质量的治疗反应,延长患者的PFS和OS时间。细胞遗传学异常和治疗反应是影响患者生存的主要因素。
Objective To explore the efficacy and prognosis of first-line autologous hematopoietic stem cell transplantation (ASCT) for newly diagnosed patients with multiple myeloma ( MM ). Methods From January 2005 to December 31, 2012, 60 patients with MM were enrolled. All patients received thalido mide or/and bortezomib-based induction therapy, then received high-dose melphalan (200 mg/m2) and autologous stem cell support to get a〉 partial response (PR) , and followed by thalidomide-dexamethasone (TD) + bortezomib as consolidation or maintenance treatment. With the follow up to December 31, 2012, the overall survival (OS) , progression free survival (PFS) and the prognostic factors, including ISS stage, response and fluorescent in situ hybridization (FISH) data of cytogenetics were analyzed. Results With a median follow up of 36.8 ( 12.0 - 102.5 ) months, the median OS and PFS estimate were not reached and 86.5 months, respectively. After transplantation, all ( 100% ) patients received very good partial response (VGPR), and 34 (56.7%) patients achieved complete response (CR) after consolidation or maintenance treatment. The patients that achieved CR resulted in long term PFS (P = 0. 030), with no difference in OS (P = 0.942). The univariate analysis showed that the abnormalities, including ! 3 q14 deletion, 1 q21 gain, IgH location and p53 deletion had the prognostic impacts. If the t(4;14) or p53 deletion was excluded, there would be no correlation between 13q14 deletion or 1 q21 gain with PFS and OS. The patients with p53 deletion had a worst survival. Conclusion There has been significant improvement in the outcome for young MM patients by using ASCT and novel drugs. Cytogenetic abnormalities and response to therapy are the mainfactors affecting the survival of patients.
