Methods The clinical data of four patients with multiple myeloma who underwent Velcade-based chemotherapy between January 2006 and November 2010 were retrospectively analyzed. The therapeutic effect was observed. Results After 3-6 courses (mean 4 courses) of Velcade-based chemotherapy, 3 patients obtained complete remission (CR) and above response, and the sufficient peripheral blood hematopoietic stem cells were collected successfully. The peripheral blood hematopoietic stem cells were collected once in three patients and twice in one patient. Sufficient number of hematopoietic stem cells (mean CD34 positive-cell 8.43×106/kg) were collected which fully met the collection requirements. Conclusion Velcade-based chemotherapy has advantages of fast action and good therapeutic effect, which can improve the collection of autologous stem cells in patients with newly-diagnosed multiple myeloma.
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.
ObjectiveTo analyze the efficacy, hospitalization cost and cost-effect of different treatments for multiple myeloma, so as to provide references for the treatment and development medical insurance payment policy of multiple myeloma.MethodsA total of 60 cases of multiple myeloma patients who were treated in the General Hospital of Shenyang Military Command from January 1st, 2013 to December 31st, 2017 were included. According to the treatment method, they were categorized into the traditional treatment group (n=37) and novel drug treatment group (n=23). The total response rate and hospitalisation expenses for patients with medical insurance of the two groups were calculated and compared, and cost-effectiveness analysis was then performed.ResultsThe overall response rate in patients in traditional treatment group was 56.76% (21/37), and in novel drug treatment group was 82.61% (19/23) (χ2=4.366, P=0.039). The annual average drug fee, annual average novel drug fee, secondary average drug fee, secondary average novel drug fee, annual average total cost, and secondary average total cost of the medical insurance patients in the novel drug treatment group were significantly higher than those in the traditional treatment group (P<0.05). The annual average cost of personal and coordinated payment for the medical insurance patients in the novel drug treatment group were 172 229.53 yuan and 48 237.51 yuan, respectively, which were significantly higher than the traditional treatment group (P<0.01). The cost-effectiveness ratio of the traditional treatment group was 884.44 yuan/%, the novel drug treatment group was 2 821.80 yuan/%, the cost-effective incremental ratio was 7 075.75 yuan/%, the incremental cost-effective ratio was 7 075.75 yuan/%, and the sensitivity analysis was consistent with the results.ConclusionsThe total response rate of novel drug treatment is significantly higher than traditional treatment. However, novel drug treatment costs higher, and patient's economic burden is also higher. The traditional treatment is superior to novel drug treatment in cost-effectiveness analysis.
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。
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。
