目的:观察低剂量反应停(thalidomide)联合地塞米松治疗多发性骨髓瘤(MM)的疗效。方法:18例MM患者中10例为初治患者、8例为复发难治性患者。反应停初始剂量为50～100mg·d-1,每周增加50mg,2周后增加到200mg·d-1;至少每天100mg/d,服用3-6个月。同时联合地塞米松10mg·d-1,连服4天,每月1次。 结果:完全缓解(CR)3例,部分缓解(PR)6例,微缓解(MR)7例,无效2例。无不能耐受的副反应。结论: 地剂量反应停联合地塞米松治疗初发和复发难治性多发性骨髓瘤安全有效。
目的:观察沙利度胺联合地塞米松(TD)治疗初治多发性骨髓瘤(MM)的疗效和毒副反应。方法:25例初治MM患者,给予沙利度胺(100mg/d起,每周增加50mg~100mg/d到200mg/d)联合地塞米松40mg/d(d1~4,9~12,17~20),28天为一疗程,至少2个疗程。与既往18例使用VAD方案治疗MM初治患者作对照。结果:观察组25例中,14例部分缓解(56％),6例进步(24％),总有效率80%。对照组18例中,部分缓解13例,进步2例,总有效率83.3%。两组总有效率无显著性差异(Pgt;0.05),但主要副作用发生率观察组明显少于对照组(Plt;0.05)。结论:沙利度胺联合地塞米松(TD)治疗多发性骨髓瘤疗效高、副作用少和耐受性好,值得进一步的临床观察和推广。老年患者(年龄gt;65岁),地塞米松减量应用,可减少副作用,且不影响疗效的发挥。
目的 构建含小鼠血管内皮生长因子（mVEGF）的重组慢病毒表达载体，包装成病毒颗粒后感染NS-1小鼠骨髓瘤细胞株，以便进一步探索VEGF在骨髓瘤病理生理机制中的作用。 方法 聚合酶链反应法扩增mVEGF基因，克隆入含嘌呤霉素抗性的pCDH慢病毒表达载体，构建出表达mVEGF的慢病毒表达载体pCDH-mVEGF；采用磷酸钙法将慢病毒系统三质粒pCDH-mVEGF、psPAX2、pMD2.G共转染293FT细胞包装病毒，分别收集转染后48 h和72 h病毒上清并感染靶细胞NS-1，初次感染72 h后开始采用嘌呤霉素筛选稳定株，筛选2周后采用ELISA法检测稳定株细胞培养上清中mVEGF的表达，建立出稳定高表达mVEGF的NS-1小鼠骨髓瘤细胞株。 结果 成功构建重组慢病毒表达质粒pCDH-mVEGF，并包装成慢病毒颗粒，感染NS-1细胞株后获得靶基因的稳定高表达。 结论 成功构建出含mVEGF的慢病毒表达载体pCDH-mVEGF，慢病毒系统能有效介导目的基因在NS-1小鼠骨髓瘤细胞株中稳定表达，病毒包装成功并能有效感染NS-1细胞，为进一步探索VEGF在骨髓瘤病理生理机制中的作用奠定了基础。
Objective To assess the effectiveness and safety of thalidomide for treating multiple myeloma in China. Methods Randomized controlled trials (RCTs) of thalidomide for multiple myeloma were collected from CNKI (1979 to 2008), CBMdisc (1979 to 2008), and VIP (1989 to 2008) databases. Other relevant journals were also handsearched. The methodological quality of the included studies was evaluated, and data analyses were performed using the Cochrane Collaboration’s software RevMan 4.3. Results A total of 9 RCTs involving 324 patients were included. As for the total effective rate and complete remission rate, significant differences were found between thalidomide + MP vs. MP alone (RR=1.34, 95%CI 1.05 to 1.70; RR=1.77, 95%CI 1.26 to 2.49) and thalidomide + VAD vs. VAD alone (RR=1.45, 95%CI 1.20 to 1.75; RR=1.73, 95%CI 1.25 to 2.39). Conclusion According to the domestic evidence, treatment for multiple myeloma with thalidomide can improve the total effective rate and the complete remission rate. However, more high–quality, large-sample, randomized, double-blind, controlled trials are required.
【摘要】 目的 探讨多发性骨髓瘤的临床特征及不同方案的疗效。 方法 回顾性分析2006年2月-2010年8月110例多发性骨髓瘤的临床特征及治疗情况，对不同方案的疗效进行比较。 结果 110例患者中Ⅲ期73例，40例伴发有基础疾病；24例接受MP方案，部分缓解10例，无变化1例，疾病进展8例，总有效率41.7%；其余86例接受联合化学疗法的患者完全缓解18例，部分缓解17例，轻微缓解30例，无变化17例，疾病进展4例，总有效率40.7%；两组总有效率差异无统计学意义（Plt;0.05）。联合化疗中PAD方案的总有效率最高，为62.5%。110例患者的中位生存期32.6个月，3年生存率为34.5%，加入沙利度胺组，总有效率为35.8%，3年生存率36.5%，联合硼替佐米治疗组总有效率为75%。 结论 多发性骨髓瘤患者多为晚期，有基础疾病，化疗后易感染，联合化疗组的有效率较MP方案高，但两组的总生存率无差异，加用新药沙利度胺或硼替佐米可以提高有效率。【Abstract】 Objective To analyze the clinical characteristics and clinical outcomes of patients with multiple myeloma treated with different regimens. Methods We retrospectively analyzed the clinical characteristics and treatments of 110 patients with multiple myeloma treated between February 2006 and August 2010, and compared the clinical outcomes of different treatment regimens. Results Seventy-three out of the 110 patients were at stage Ⅲ, and 40 patients had one or two more fundamental diseases. Twenty-two patients received MP regimen, among whom 10 gained partial alleviation, 1 had no change and 8 were aggravated with a total effective rate of 41.7%. Another 86 cases received combination chemotherapy, and among them, 18 gained complete alleviation, 17 attained partial alleviation, 30 achieved mild alleviation, 17 had no change, and 4 were aggravated with a total effective rate of 40.7%. In terms of the total effective rate, there was no statistical difference between these two groups. PAD-treated group had a highest effective rate of 62.5%. The median survival time for all the patients was 32.6 months; 3-year survival rate was 34.5%. For patients treated with thalidomide, the total effective rate and 3-year survival rate were 35.8% and 36.5% respectively, while for patients treated with bortezomib, the effective rate was 75%. Conclusions Patients with multiple myeloma at a late stage complicated with fundamental diseases can develop infections after chemotherapy. Total effective rate of combination chemotherapy is higher than that of MP treatment, but survival rate of the two treatments have no statistical difference. The effective rate can be increased after the using of novel agents such as thalidomide and bortezomib.
目的 评价国内干扰素（INF）治疗多发性骨髓瘤（MM）的疗效与安全性。 方法 计算机检索中国期刊全文数据库（1989年－2011年）、中国生物医学文献数据库（1989年-2011年）和中文科技期刊全文数据库（1989年－2011年），并手工检索所有纳入文献的参考文献，纳入INF治疗MM的随机对照试验（RCT）。评价纳入研究的方法学质量并进行资料提取后，采用RevMan 5.0软件进行Meta分析。 结果 共纳入10个RCT，包括366例患者。Meta分析显示，INF联合美法仑+泼尼松（MP） 方案与单用MP方案比较，其总有效率差异有统计学意义[OR=4.52，95% CI（1.84，11.10），P=0.001]；INF联合长春新碱+多柔比星+地塞米松/泼尼松[VAD（P）]与单用VAD（P）方案比较，其总有效率[OR=4.13，95% CI（1.53，11.14），P=0.005]和完全缓解率[OR=3.88，95% CI （1.49，10.16），P=0.006]差异也均有统计学意义；INF+其他化疗方案与单用化疗方案比较，其总有效率[OR=2.57，95%CI（1.11，5.96），P=0.03]和完全缓解率[OR=3.17，95% CI（1.21，8.27），P=0.02]，差异均有统计学意义。 结论 目前国内研究结果表明，INF与化疗联合运用能增加MM治疗的总有效率和缓解率，但由于纳入研究样本量小且质量较低，上述结论尚需要高质量、大样本的随机与双盲对照试验加以分析。
Objcetive To assess the efficacy and safety of lenalidomide plus dexamethasone (LD) compared with placebo plus dexamethasone (PD) for relapsed or refractory multiple myeloma. Methods Data were searched in The Cochrane Library (Issue 3, 2010), MEDLINE (with PubMed, 1966 to Nov. 2010), EMbase (1984 to Nov. 2010), CBMdisc (1978 to Nov. 2010), and CNKI (1979 to Nov. 2010), and also searched in clinical trials register for ongoing studies and completed studies with unpublished data. The references of the included studies and relevant supplement or conference abstracts were handsearched. Randomized controlled trials were included. The data were extracted, and then the quality of the included studies was assessed by two reviewers independently. RevMan 5.0 software was used for meta-analyses for studies with low heterogeneity. Results Two studies involving 704 participants were included. One was high quality study, while the other was unclear about randomization and allocation concealment. The adverse outcomes of LD, such as mortality (RR=0.78, 95%CI 0.62 to 0.97, P=0.03) and incidence of disease progression (RR=0.16, 95%CI 0.08 to 0.34, Plt;0.000 01), were better than those of PD, which had significant differences. The overall response rate was higher in the LD group than in the PD group (RR=2.75, 95%CI 2.22 to 3.41, Plt;0.000 01). The incidence of thrombotic event (RR=3.20, 95%CI 1.78 to 5.73, Plt;0.000 1), the Grade Three and Grade Four neutropenia (RR=10.20, 95%CI 5.76 to 18.08, Plt;0.000 01), the Grade Three and Grade Four thrombocytopenia (RR=2.08, 95%CI 1.28 to 3.38, P=0.003), and the incidence of drug withdrawal or dosage reduction due to adverse reactions (RR=1.34, 95%CI 1.21 to 1.49, Plt;0.000 01) were all higher in the LD group than in the PD group. Conclusion The efficacy of LD is superior to that of PD for relapsed or refractory multiple myeloma, but the incidence of drug adverse events, such as thrombosis, Grade Three or Grader Four neutropenia or thrombocytopenia, is also higher than that of PD, which has to be prevented positively.
Objective To investigate the causal relationship between resistin and multiple myeloma (MM). Methods A two-sample Mendelian randomization analysis was conducted using genetic variants (SNPs) associated with resistin as instrumental variables and MM genome-wide association study (GWAS) data as the outcome event. Five analysis methods, including inverse-variance weighted (IVW), MR-Egger, weighted median, weighted model, and simple model were used to assess the causal impact of resistin on the risk of MM. Results None of the five analysis methods showed a causal relationship between resistin and multiple myeloma (P>0.05). Sensitivity analysis indicated consistent and robust results, with no evidence of horizontal pleiotropy, heterogeneity, outliers, or individual SNPs influencing the findings. Conclusion This Mendelian randomization study provides no support for a causal relationship between resistin and the risk of multiple myeloma.
