目的 测定多发性骨髓瘤(MM)患者血清胱抑素C (Cys-C) 的水平,探讨Cys-C与国际分期体系(ISS)、血β2-微球蛋白、溶骨性损害等指标的关系。 方法 收集2008年1月-2010年9月32例初治和8例复发的MM患者作为研究对象,同时收集40例健康体检者的检查资料作为对照组,测定血清Cys-C、血肌酐(Scr)、血β2-微球蛋白。采用核素全身骨显像(ECT)观察患者的溶骨性病变部位数。 结果 患者血清Cys-C水平(1.40 mg/L)明显高于健康对照组(0.90 mg/L)(P<0.01);在MM患者中Cys-C比Scr更敏感,能反映肾小球滤过率;血清Cys-C水平与ISS分期晚,血β2-微球蛋白升高以及溶骨性病变进展密切相关。 结论 MM患者的Cys-C水平高于健康者。Cys-C是骨髓瘤肾损害的早期敏感标志物,与肿瘤负荷及溶骨性损害密切相关,可作为评价肿瘤负荷的潜在指标。Objective To evaluate the serum levels of cystatin-C in patients with multiple myeloma (MM), and to explore its possible correlations with clinical data, including ISS stage, serum β2-microglobulin, and advanced lytic lesions. Methods From January 2008 to September 2010, serum cystatin-C, creatinine (Scr), and β2-microglobulin in 32 patients with MM, 8 patients with relapsed disease, and in 40 healthy controls were detected by automatic biochemistry analyzer detection. According to skeleton ECT, grading of osteolytic lesion was observed. Results The levels of serum cystatin-C of patients with MM were significantly higher than those of the controls. Serum cystatin-C could reflect the glomerular filtration rate , and was more sensitive than Scr in patients with renal lesion. Serum cystatin-C had ber correlations with advanced ISS stages, high levels of serum β2-microglobulin, and extensive bone diseases. Conclusion Serum cystatin-C is a sensitive marker of renal lesion in patients with MM, it could be a potential indicator to assess the tumor burden.
ObjectiveTo systematically review the effect of thalidomide as first-line therapy on postrelapse survival rate of patients with multiple myeloma (MM). MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 1, 2007) and Web of Science were searched to collect randomized controlled trials (RCTs) about thalidomide as first-line therapy for MM from 2006 to 2011. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.1 software. ResultsA total of 16 RCTs involving 6097 patients were included. The results of meta-analysis showed that, compared with the chemotherapy alone group, early application of thalidomide could significantly decrease the postrelapse survival rate (HR=1.23, 95%CI 1.05 to 1.45, P=0.002). Subgroup analysis showed that, compared with the chemotherapy alone group, thalidomide maintenance therapy after autologous stem cell transplantation (ASCT) couldn’t decrease the postrelapse survival rate (HR=0.90, 95%CI 0.57 to 1.41, P=0.64), but thalidomide induction therapy before ASCT (HR=1.21, 95%CI 1.01 to 1.45, P=0.04) and thalidomide induction therapy before ASCT combined maintenance therapy after ASCT (HR=1.41, 95%CI 1.13 to1.76, P=0.002) could significantly decrease the postrelapse survival rate. ConclusionCurrent evidence shows that, thalidomide maintenance therapy after ASCT for MM is a better therapy regimen. It couldn’t decrease the survival rate after recurrence, but could increase the disease-free survival (DFS) and overall survival (OS) of patients with MM. Due to the limited quality of included studies, the above conclusion still needs to be verified by more high quality studies.
ObjectiveTo systematically review the efficacy and safety of non-myeloablative stem cell transplantation (NST) for the treatment of multiple myeloma (MM) after first autologous stem cell transplantation. MethodsSuch databases as The Cochrane Library (Issue 5, 2013), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were electronically searched to collect studies investigated the efficacy and safety of NST and non-NST for the treatment of MM after first autologous stem cell transplantation from the date of their establishment to June 13th 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of the included studies. Then meta-analysis was performed using RevMan 5.1 software. ResultsSeven studies involving 1 961 participants were included, of which 626 cases were in the NST group and 1 335 cases were in the non-NST group. The results of meta-analysis showed that no significant difference was found between both groups in the overall survival rate (HR=1.06, 95%CI 0.78 to 1.44, P=0.69) and progress-free survival rate (HR=0.92, 95%CI 0.76 to 1.11, P=0.39). However, there were significant differences in the complete remission rate (RR=1.29, 95%CI 1.13 to 1.48, P=0.000 2) and treatment-related mortality rate (RR=3.40, 95%CI 2.27 to 5.07, P < 0.000 01). ConclusionThe efficacy of NST is not superior to non-NST for patients with MM which has received first autologous stem cell transplantation. It is not sufficient to recommend NST as the first-line treatment of MM based on the currently available evidence.
目的 总结多发性骨髓瘤(multiple myeloma, MM)的发病特征及临床特征,分析比较不同治疗方案对MM的疗效及不同类型与不同临床特征的MM治疗效果。 方法 回顾性分析2003年1月-2008年1月128例MM患者的发病和临床特征,以及与治疗效果的关系,并对不同治疗方案、不同类型间的疗效进行比较。 结果 MM患者发病的中位年龄为59岁,临床上以不明原因的骨痛、贫血、感染和球蛋白增高为主要表现。128例患者中行方案一(马法兰、强的松/地塞米松、反应停)的总有效率为53.3%(32/60);方案二(环磷酰胺、长春新碱、马法兰、强的松、卡氮芥、阿霉素)为44.4%(8/18);方案三(长春新碱、阿霉素/表阿霉素/脂质体阿霉素、地塞米松)为68.5%(24/35),方案四(硼替佐米、地塞米松/反应停)的总有效率为86.6%(13/15)。方案一和方案二间、方案三和方案四间疗效差异无统计学意义(Pgt;0.05),方案三、方案四的疗效均优于方案一和方案二(Plt;0.05)。IgG型总有效率为63.2%(48/76),IgA型为60.9%(14/23),kappa轻链型为42.8%(6/14),lammda轻链型为46.2%(6/13)。IgG型和IgA型间的疗效差异无统计学意义(Pgt;0.05),但IgG型、IgA型的疗效均优于kappa轻链型和lammda型(Plt;0.05)。不同类型及使用不同方案的患者,其中位生存期及3年和5年的生存率差异无统计学意义(Pgt;0.05)。 结论 MM患者发病高峰年龄介于40~70岁,骨痛和贫血是最常见的首发症状。长春新碱、阿霉素/表阿霉素/脂质体阿霉素、地塞米松以及硼替佐米、地塞米松/反应停方案总体疗效相当,但后者完全缓解率高于前者。
ObjectiveTo investigate the efficacy and safety of bortezomib combined with dexamethasone and thalidomide regimens on aged patients with multiple myeloma. MethodsA total of 166 multiple myeloma patients were selected between January 2009 and June 2013; all patients were assigned to regimens of T-VD or T-VAD named T-VD group or T-VAD group (with 25 patients in T-VD group and 29 in T-VAD group). Efficacies and toxicities were analyzed and compared after two cycles. ResultsOverall response rate (OR) in T-VD group was 84.0%; there was 6 patients achieved complete response (OR) or very good partial response (VGPR) (24.0%). However, Overall response rate (OR) in T-VAD group was 48.3%; there was only one patient achieved CR or VGPR (3.4%); significant difference between two groups was found (χ2=7.513, P<0.05). The major adverse reactions were debilitation, nausea, vomiting, myelo-suppression, cardiac toxicity, and peripheral neuropathy. There were highest incidence of nausea and vomiting in T-VAD group compared to T-VD group (χ2=5.794, P<0.05). ConclusionBortezomib combined with dexamethasone and thalidomide regimens is effective and safe, which can be widely used for aged patients with multiple myeloma.
目的:探讨蛋白酶体抑制剂——硼替佐米对初治多发性骨髓瘤的疗效及对移植造血干细胞采集的影响。方法:对一例初发的中年男性多发性骨髓瘤患者使用硼替佐米+地塞米松+反应停(VTD)的方案进行化疗,获得缓解后采集外周血造血干细胞。结果:应用以硼替佐米为基础的方案治疗3个疗程后,患者即获得完全缓解;完成4个疗程化疗后成功采集足够数量的外周血造血干细胞;完成6个疗程化疗后,进入维持治疗,至今已完全缓解17个月。治疗过程中除恶心、呕吐外无其他明显不良反应。结论:硼替佐米用于初治多发性骨髓瘤有良好的治疗效果,不良反应少,不影响造血干细胞采集。
目的:多发性骨髓瘤(Multiple Myeloma,MM)患者约有80%伴有贫血,临床上多数患者以输血方式纠正贫血。重组人促红细胞生成素(recombinant human erythropoietin, rHuEPO)用于治疗MM患者的贫血尽管有效,但以何等剂量、应用多长时间疗效较佳尚无定论。目的: 观察持续使用大剂量rHuEPO对MM患者贫血的纠正作用及效果。方法:87例诊断明确的多发性骨髓瘤伴有贫血的患者,开始连续每天使用重组人促红细胞生成素4万单位,皮下注射,共5d;以后每周使用一次,每次4万单位皮下注射,间断补充铁剂。对照组90例选自同期住院的诊断明确的多发性骨髓瘤患者,当其贫血症状明显时或血红蛋白水平低于60 g/L时,给予输血纠正其贫血,使多数患者血红蛋白水平维持在80 g/L~100 g/L以上。两组患者化疗方案不做特殊规定,整过研究观察期6月。结果: rHuEPO组在使用rHuEPO后2周其血红蛋白开始上升,中位反应时间16d;1月半至2月血红蛋白可升至正常水平,达正常血红蛋白水平的中位时间51d。进入研究后3月和6月时,rHuEPO组生活幸福感指数(INLH)明显优于输血组,分别为6927±318(Plt;005)和7216±283(Plt;001)与5835±289和5776±324。6月后,rHuEPO组平均每例直接费用成本1075440元,明显低于输血组需要达到同样效果所需的每例2070420元。结论:大剂量rHuEPO治疗MM相关性贫血优于输血,其起效快、疗效好,患者生活幸福感改善明显,费用成本低,安全性较好。
