自体造血干细胞移植治疗多发性骨髓瘤

 自体造血干细胞移植（ASCT）治疗多发性骨髓瘤进展较大。与常规方案相比，ASCT提高了患者的完全缓解（CR）、无事件生存（EFS）和总生存率（OS）。高龄、肾衰竭并非ASCT的禁忌证。双次ASCT可提高CR率，对长期EFS率、OS率影响仍需观察。改进预处理方案、选择移植时机、改进移植后巩固治疗可以提高疗效。     

靶向新药时代自体造血干细胞移植在多发性骨髓瘤治疗中的作用

多发性骨髓瘤（MM）是浆细胞恶性克隆性疾病,自体干细胞移植（ASCT）的加入,增加了大剂量化疗在MM治疗中的优势,使部分患者达到长期生存.即使在靶向新药时代ASCT仍可以明显提高治疗的反应率.靶向新药在ASCT前后联合应用,可辅助提高ASCT的疗效,这是目前使用靶向新药的趋势,但其仍不能取代ASCT在MM治疗中的地位.研究更为合理、有效、低毒的治疗方案是今后的方向.     

硼替佐米联合沙利度胺和地塞米松方案序贯造血干细胞移植治疗初治多发性骨髓瘤的临床观察

目的探讨硼替佐米联合方案序贯造血干细胞移植治疗初治多发性骨髓瘤的疗效和相关毒副作用。方法选取2006年6月至2014年4月初治多发性骨髓瘤33例为研究对象,采用硼替佐米+沙利度胺+地塞米松(BTD)方案诱导治疗(2⁷个疗程),其中14例继以马法兰预处理后行造血干细胞移植;所有患者均接受沙利度胺+地塞米松(TD)或来那度胺+地塞米松(LD)方案维持治疗。随访57个疗程),其中14例继以马法兰预处理后行造血干细胞移植;所有患者均接受沙利度胺+地塞米松(TD)或来那度胺+地塞米松(LD)方案维持治疗。随访5⁹2个月,观察疗效及不良反应。结果 BTD方案诱导治疗后获得完全缓解(CR)、很好的部分缓解(VGPR)、部分缓解(PR)的例数分别为8例(24.2%)、11例(33.3%)、12例(36.4%),总有效率(ORR)为94.0%。14例移植患者中,移植后获VGPR 9例,单用BTD组和序贯移植组的中位随访时间分别为51和32个月,中位生存时间尚未获得,预期3年无进展生存率分别为42.3%和58.7%。BTD方案的不良反应主要为血细胞减少、周围神经病变、带状疱疹病毒感染、便秘、感染和乏力等,大多数患者给予对症治疗后可耐受。结论以硼替佐米联合诱导治疗并以造血干细胞移植序贯治疗多发性骨髓瘤,毒副反应可耐受,疗效显著,生存期较长。     

新药时代自体造血干细胞移植在多发性骨髓瘤中的应用前景*

自体干细胞移植（ASC T）在传统化疗时代已成为65岁以下初诊多发性骨髓瘤（MM）的标准一线治疗。随着新型靶向药物为基础的化疗在诱导、巩固和维持治疗阶段的广泛应用,MM的缓解率得到显著提高,因此是否需要ASCT成为了新药时代关注的焦点。目前现有的资料仍然支持ASCT是符合条件的初诊MM患者的一线治疗,新药作为ASCT前诱导治疗以及ASCT后巩固、维持治疗有助于进一步提高缓解率,延长无进展生存时间。但今后仍需要开展更多前瞻性临床试验进一步明确ASCT在MM中的作用、进一步优化治疗方案,以期实现MM治愈的目标。     

造血干细胞移植治疗多发性骨髓瘤

 自体造血干细胞移植（auto-HSCT）显著提高了65岁以下多发性骨髓瘤（MM）患者的疗效,早期进行auto-HSCT已成为年轻初发MM患者的标准治疗方法。美法仑200 mg／m2目前仍被认为是最佳的预处理方案。对于首次自体移植后未达到非常好的部分缓解（VGPR）及以上疗效的患者,推荐采用序贯双次auto-HSCT以进一步提高疗效。新的治疗MM药物在auto-HSCT前和预处理中的应用可提高自体干细胞移植（ASCT）疗效。异基因造血干细胞移植（allo-HSCT）虽然 完全缓解（CR）率较高,但因具有较高的移植相关毒性,患者的长期生存率并不比ASCT高。减低剂量的allo-HSCT由于预处理毒性小,移植相关死亡率低,将可能成为一种安全有效的治疗方法。ASCT结合非清髓的allo-HSCT的疗效目前还需大样本的研究来证实。     

自体造血干细胞移植治疗多发性骨髓瘤预处理方案的研究进展

大剂量美法仑(Mel)是多发性骨髓瘤(MM)疗效最肯定的预处理方案.全身放疗(TBI)联合Mel的疗效不优于单用Mel,但不良反应增加.在年轻患者中Mel 200 mg/m2疗效优于Mel 100~140 mg/m2.MelBU、TBC、BCV、MET、MTC、MelBCNU、VMel、MTC以及含有苯达莫司汀的预处理方案可获得同大剂量Mel类似的治疗效果.新预处理方案的效果需要更多临床试验证实.     

Novel agents-based regimens as induction treatment prior to autologous stem-cell transplantation in newly diagnosed multiple myeloma: a meta-analysis of randomized controlled trials

To investigate the effect of novel agents like bortezomib, lenalidomide and thalidomide as part of induction treatment prior to autologous stem-cell transplantation (ASCT) for previously untreated patients with multiple myeloma, we performed a meta-analysis of randomized controlled trials (RCTs). Medline, Embase, the Cochrane controlled trials register and the Science Citation Index were searched for RCTs of novel agents as part of induction therapy before ASCT. Three RCTs of bortezomib, two RCTs of thalidomide and no RCT of lenalidomide were identified, covering a total of 2,316 subjects. Due to different mechanisms of action, we performed a subgroup analysis by type of agent (thalidomide or bortezomib). The weighted risk ratios of a complete response (CR) were 4.25 [95% CI: 2.44-7.41] (p < 0.001) for bortezomib and 1.66 [95% CI: 1.15-2.38] (p = 0.007) for thalidomide, respectively. The summary hazard ratios for progression-free survival (PFS) were 0.73 [95% CI: 0.59-0.89] (p = 0.002) for bortezomib and 0.68 [95% CI: 0.59-0.79] (p < 0.001) for thalidomide, respectively. The corresponding ratios for overall survival (OS) were 0.87 [95% CI: 0.64-1.18] (p = 0.37) and 0.88 [95% CI: 0.73-1.05] (p = 0.14), respectively. Additionally, there was a statistically significant heterogeneity between subgroups (thalidomide and bortezomib) for CR (p = 0.005) but nonsignificant for PFS (p = 0.64) and OS (p = 0.97). In conclusion, our analysis showed novel agents as induction treatment prior to ASCT improved CR and PFS but not OS.     

Comparison between autologous and allogeneic stem cell transplantation as salvage therapy for multiple myeloma relapsing/progressing after autologous stem cell transplantation

Allogeneic stem cell transplantation (allo‐SCT) offers a clinical option to young patients with multiple myeloma (MM) relapsing/progressing after autologous SCT (ASCT); however, this claim remains debatable. Thus, in this retrospective study, we analyzed 526 patients with MM who underwent SCT for MM relapsing/progressing after the prior ASCT using the registry data of the Japan Society for Hematopoietic Cell Transplantation (2001‐2015) and compared overall survival (OS) between allo‐SCT (n = 192) and autologous stem cell retransplantation groups (ReASCT; n = 334) based on risk factor points. Significant adverse factors for OS in all patients were (1) male sex, (2) less than partial response to SCT, (3) performance status of 2 to 4, and (4) short duration from the prior ASCT. We scored factor 2 as 1 point, factor 3 as 2 points, and factor 4 as 0, 1, or 2 points for more than 30, 9 to 30, or less than 9 months, respectively. We categorized patients into three risk subgroups based on their total points (0, 1‐3, and 4‐5 points), indicating the usefulness of this scoring system for prognosis prediction and treatment selection. Subgroup comparison revealed OS after ReASCT to be higher than that after allo‐SCT in the intermediate‐risk subgroup comprising the largest population (28.2% vs 21.5%, P < .004). We observed no significant advantages of allo‐SCT over ReASCT in the low‐ and high‐risk subgroups. These findings suggest that ReASCT is more advantageous than allo‐SCT in many patients with MM relapsing/progressing after the prior ASCT. However, long‐term survival patients were noted only in the allo‐SCT group, and allo‐SCT could exhibit clinical efficacy, particularly in the low‐risk group. While further examination is warranted, allo‐SCT could be a potential tool for a specific population with MM relapsing/progressing after the prior ASCT.     

Symptom burden after autologous stem cell transplantation for multiple myeloma

BACKGROUND: Multiple myeloma (MM) is the most common indication for high-dose chemotherapy with autologous stem cell transplantation (ASCT) in the U.S. and can be associated with substantial morbidity. Thorough assessment and understanding of symptoms and risk factors for symptom development after ASCT are logical first steps toward developing strategies aimed at reducing the symptom burden associated with this procedure. METHODS: The authors performed a prospective evaluation of symptom burden among 64 patients with myeloma who underwent ASCT. Symptom data were collected using the M. D. Anderson Symptom Inventory (MDASI) at 4 time points: baseline, the day of stem cell infusion (Day 0), nadir of counts, and Day 30. Univariate analysis was performed to correlate pretransplantation variables with post-transplantation symptom burden at these time points. RESULTS: MDASI scores increased significantly throughout transplantation, with most patients returning to baseline by Day 30 after the procedure. Patients with the highest MDASI scores at baseline had the highest MDASI scores at nadir (P= .02). Patients with prolonged time to transplantation and women had a trend toward higher nadir global symptom severity scores. These groups, as well as patients aged >60 years, had a trend toward higher nadir interference scores. CONCLUSIONS: ASCT for MM was associated with significant but reversible symptom burden during the first 30 days, and the baseline symptom burden was the most important predictor of symptom burden after transplantation. The MDASI was useful as a tool for following the symptom burden associated with ASCT and may be used to evaluate interventions aimed at reducing transplantation-related morbidity in these patients.

Efficacy of up-front treatment with a double stem cell transplantation in multiple myeloma

BACKGROUND: We report the outcome of 53 patients with multiple myeloma (MM), who received autologous stem cell transplantation (ASCT) from April 1996 to September 2004 at our institution and who survived for more than 3 months after the transplant. METHODS: Following the first ASCT, 36 patients underwent an up-front second SCT, which consisted of either an ASCT (n = 24) or a reduced-intensity conditioning allogeneic stem cell transplant (RIST) (n = 12). Seventeen patients were given maintenance treatment. RESULTS: Seventy-seven percent of the patients (n = 41) showed an objective response to the initial therapy prior to the first ASCT. Overall, 60.4% (32 out of 53) and 32.1% (17 out of 53) of the patients had a complete response (CR) and partial response (PR) after the first ASCT, respectively. At the time of analysis, 34 patients (64.2%) were still alive. With a median follow-up of 32 months (range 9-98), the estimated progression-free survival (PFS) and overall survival (OS) at 5 years were 17.0 and 34.9%, respectively. Multivariate analysis revealed that the second SCT, normal hemoglobin and <50% marrow plasma cells were associated with an improved PFS. A second SCT, CR to the first SCT, female gender and an absence of advanced bone lesions were associated with a better OS. CONCLUSIONS: A second SCT is the most significant factor for an improved PFS and OS after the first ASCT (P < 0.001, respectively). Up-front double SCT is needed to improve the OS and PFS in patients with MM.     

The tumor kinetics of multiple myeloma following autologous stem cell transplantation as assessed by measuring serum-free light chains

In multiple myeloma, changes in serum-free immunoglobulin light chains (FLC) are a more rapid indicator of treatment response than intact immunoglobulin due to their shorter serum half-life. The present study analysed the changes in serum FLC after autologous peripheral blood stem cell transplantation (PBSCT) in 19 patients. The majority of myeloma patients (18 of 19) undergoing PBSCT had a rapid fall in FLC concentrations. In all 11 of 19 patients with raised tumor FLC, it fell within 48 h following high-dose melphalan. In patients with monoclonal intact immunoglobulin, the tumor FLC fell quicker (median half-life 4.3 days) than the monoclonal intact immunoglobulin (median half-life 14 days). FLC recovery occurred after (13 of 19) or around the time of neutrophil engraftment (6 of 19). With a median follow up of 220 days post-transplant, 16 of 19 patients have a normal FLC ratio and 3 of 19 have an elevated tumor FLC/abnormal ratio. FLC assays provided a sensitive monitor of changes in tumor and non-tumor plasma cells after PBSCT. This assay is potentially valuable as a marker of chemosensitivity, as an indicator of residual tumor and indicated time to lymphocyte engraftment. Further follow-up is required to ascertain whether differences in the kinetics of FLC responses have any prognostic clinical utility.     

新药诱导后自体干细胞移植巩固治疗对不同危险度骨髓瘤患者的作用探讨*

目的：探讨自体造血干细胞移植（autologous hematopoietic stem cell transplantation ,ASCT）作为新药诱导后的巩固治疗对不同危险分层骨髓瘤患者的无进展生存时间（progression-freesurvival ,PFS）及总生存时间（over all survival,OS）的影响。方法：回顾性分析2006年8 月至2011年7 月在本科行自体干细胞移植巩固治疗的67例多发性骨髓瘤患者,根据ISS 分期及FISH检测结果为基础的最新IMWG 预后标准分为高危组17例,中危组24例,低危组26例。另选取同时期67例接受化疗作为巩固治疗的骨髓瘤患者进行年龄、危险分层配对,比较移植组与化疗组的PFS 和OS差异。所有患者前期均接受硼替佐米和/或沙利度胺为主的诱导治疗。结果：所有患者诱导治疗后均达到部分缓解（partial remissive disease ,PR）以上疗效,移植组与化疗组vs . 接近完全缓解率（nCR/CR）差异无统计学意义（44.8% vs. 37.3% ,P=0.380）。 巩固治疗后,高、中、低危移植组患者中位nCR/CR率分别由47.1% ,37.5% ,50.0% 增加为62.9% ,62.5% ,61.5% 。高危患者移植巩固后中位PFS（30.5 个月vs. 11.2 月,P<0.001）和OS（85.5 vs. 34个月,P=0.015）均明显延长;中危移植组和化疗组中位PFS 和OS无统计学差异（P>0.05）;低危移植组患者与化疗组相比,中位PFS 延长（34.8 vs. 17.6 个月,P=0.012）,OS差异无统计学意义（P>0.05）。 结论：在硼替佐米和/或沙利度胺为基础的新药诱导治疗后,高危骨髓瘤患者更能从自体造血干细胞移植巩固治疗中获益,进而延长生存。     

Addition of bortezomib to high-dose cyclophosphamide therapy as a conditioning regimen for autologous peripheral blood stem cell harvest leads to an increased yield of hematopoietic stem cells

Peripheral blood stem cell harvest (PBSCH) is a crucial procedure for autologous stem cell transplantation in patients with multiple myeloma. We herein report a retrospective study to verify the usefulness of bortezomib and high-dose cyclophosphamide therapy (Bor-HDCY) as a conditioning regimen for PBSCH. Thirty-three patients were evaluated. The median age at the first apheresis was 61 (interquartile range, 53–64) years old, and 18 (54.5%) patients were male. Bor-HDCY was performed in 15 patients, and HDCY was performed in 18. In the patients who underwent Bor-HDCY, the CD34⁺ cell count at the first apheresis was significantly higher than in the others (P<0.01), and the total CD34⁺ cell count also tended to be high (P=0.0933). In terms of apheresis days, two-thirds of the patients who underwent HDCY had two-day apheresis, whereas most who underwent Bor-HDCY had one-day apheresis. According to univariate analysis, Bor-HDCY (P<0.01), VRd (Bor, lenalidomide, and dexamethasone) as induction therapy (P=0.0529), and ≥VGPR before PBSCH (P=0.0767) were factors associated with a higher CD34⁺ cell count at first apheresis. Although multivariate analysis showed that there were no independently significant factors influencing the CD34⁺ cell count at the first apheresis, the stepwise selection method revealed that only the Bor-HDCY regimen remained in the final model (P<0.005). Bor-HDCY may be a useful conditioning regimen for increasing the CD34⁺ cell yield.
