Long-term results favor allogeneic over autologous hematopoietic stem cell transplantation in patients with refractory or recurrent indolent non-Hodgkin's lymphoma.

BACKGROUND: The aim of this study was to compare the outcomes of high-dose therapy (HDT) and allogeneic versus autologous hematopoietic stem cell transplantation (SCT) in patients with refractory or recurrent indolent non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: From January 1991 to March 2000, 112 patients underwent HDT followed by either autologous (68 patients) or allogeneic (44 patients) SCT for refractory or recurrent indolent NHL. Prior conventional chemotherapy had failed in all patients. RESULTS: The two groups were similar with respect to age at transplantation, gender, histological subtypes, number of chemotherapy regimens received before transplantation and International Prognostic Index scores. The median time from diagnosis to transplantation was longer in the autologous than in the allogeneic SCT group (46 versus 27 months, P = 0.002). In the allogeneic SCT group the median follow-up time was 53 months (range 21-113), and the overall survival (OS) and disease-free survival (DFS) rates were 49% and 45%, respectively. After a median follow-up time of 71 months (range 22-109), in the autologous SCT group, the OS and DFS rates were 34% and 17%, respectively. Patients who underwent autologous SCT were more likely to have chemosensitive disease (P <0.001) and were more likely to be in complete remission at the time of transplantation (P = 0.001) than those who underwent allogeneic SCT. However, the probability of disease progression was significantly higher in the autologous SCT group than in the allogeneic SCT group (74% versus 19%, P = 0.003). CONCLUSIONS: Patients who undergo HDT with allogeneic SCT for refractory or recurrent indolent NHL have lower relapse rates but higher treatment-related mortality rates than patients who undergo autologous SCT. However, with the development of non-myeloablative preparative regimens, which can decrease treatment-related mortality, patients with recurrent indolent NHL should be considered for controlled trials of allogeneic transplantation if they have a human leukocyte antigen-identical donor.

Autologous stem cell transplantation in patients with primary amyloidosis: a nation-wide survey

Due to poor prognosis with conventional therapy, high-dose therapy (HDT) with autologous stem cell transplantation (ASCT) is considered for treatment in patients with primary amyloidosis (AL). Only single centre series are available on the feasibility and efficacy of this approach. Altogether 20 AL patients (11 males, 9 females, median age 54 years) were included in HDT protocols in 5 Finnish transplant centres between 1997 and 2003. Twelve patients were mobilized with granulocyte colony-stimulating factor (G-CSF) alone and 8 patients with a combination of cyclophosphamide and G-CSF. Sixteen patients (80%) went on to high-dose melphalan. Early transplant-related mortality was 25%. Nine out of 11 evaluable patients showed improvement or stabilization of AL. The overall survival of the transplanted patients is 69% (median follow-up 13 months). After a median follow-up of 26 months for the living patients, only 2 patients (18%) have shown progression of AL. This retrospective nation-wide analysis shows that HDT with ASCT leads to improvement or stabilization of AL in the majority of the patients who survive the immediate posttransplant period. A randomized multicentre trial is needed to show whether ASCT is superior to conventional therapy in patients with AL.     

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。      

Outpatient Autologous Stem Cell Transplants for Multiple Myeloma: Analysis of Safety and Outcomes in a Tertiary Care Center

BackgroundAutologous stem cell transplant (ASCT) is the preferred consolidation strategy to treat eligible patients with multiple myeloma (MM) and related plasma cell dyscrasias. Given the increasing volume of patients and longer wait time, outpatient ASCT for MM is the standard of care at the Vancouver General Hospital.Patients and MethodsPatients with MM, POEMS syndrome, and amyloidosis undergoing ASCT were included in this analysis. We analyzed patient characteristics, the number of patients requiring admission, duration of admission, 30-day and 100-day mortality, and overall survival.ResultsBetween January 2007 and June 2016, 724 patients underwent 752 ASCTs. Of these, 702 were first ASCTs, 44 were second, and 6 were third. The median age was 60 years (interquartile range [IQR], 54-65 years). Reasons for ASCTs were MM (96.9%) amyloidosis (2.4%), and POEMS syndrome (0.7%). There were 431 (59.5%) males in this group. The median time from diagnosis to transplant was 5 months. Conditioning was melphalan 200 mg/m² for 89.6% of the patients. Admission to the inpatient ward was required by 245 (32.6%) patients within the first 30 days. The median time to admission was 9 days post-transplant (IQR, 5-13 days). The median duration of admission was 6 days (IQR, 3-9 days). The day 100 all-cause mortality rate was 0.9%, and transplant-related mortality was 0.4%.ConclusionOutpatient ASCT is a safe and feasible treatment strategy with low transplant-related mortality. Overall resource utilization is significantly lower than inpatient ASCT: however, this requires a multidisciplinary approach with close follow-up.     

IgD multiple myeloma a descriptive report of 17 cases: survival and response to therapy

Background

Immunoglobulin D multiple myeloma (MM) is rare and has a poorer prognosis than other MM isotypes.

Design and methods

Seventeen patients (pts) diagnosed from 1993 to 2009 with IgD MM were selected from six institutions of Multiple Myeloma Latium-Region GIMEMA Working Group.

Results

Median age was 55 years, 14 patients had bone lesions, eight had renal impairment with estimated glomerular filtration rate (eGFR) < 50 ml/min, one serum calcium ≥ 12 mg/dl, 11 had lambda light chains, five stage III of ISS, six with chromosomal abnormalities. Six pts received conventional chemotherapy (CT): five melphalan + steroids based regimens. Eleven underwent high-doses of chemotherapy with autologous stem cell transplantation (HDT/ASCT), five single and six tandem ASCT: six received bortezomib and/or thalidomide as induction therapy and five VAD. Thalidomide maintenance was used in two pts: one in HDT/ASCT and one in CT group; bortezomib was used in one patient after HDT/ASCT. At a median follow up of 38 (range 19-60) and 50 months (range 17-148) for pts treated with CT and HDT/ASCT, respectively, the overall response rate (ORR) was 83% and 90%. In the group of patients treated with CT, median overall survival (OS) was 34 months (95% CI 15- 54 months), median progression free survival (PFS) was 18 months (95% CI 3-33 months) and median duration of response (DOR) was 7 months (95% CI 5-9 months). Median OS, PFS and DOR were not reached at the time of this analysis in the HDT/ASCT group of patients. Death was observed in 27.3% of pts treated with HDT/ASCT and in 66.7% undergone CT.

Conclusions

Despite the retrospective analysis and the small number of pts our study showed that the use of HDT/ASCT seems to improve also the prognosis of IgD MM patients. Treatment options including new drugs, before and after stem cell transplantation, may further improve the outcomes of 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.     

Engraftment and outcomes following autologous stem cell transplantation in Hodgkin lymphoma patients mobilized with plerixafor

Plerixafor has been used to improve peripheral blood stem cell (PBSC) mobilization in multiple myeloma, non‐Hodgkin lymphoma, and very recently in Hodgkin lymphoma (HL) patients. Because prior studies have suggested that mobilization with plerixafor affects the composition of mobilized cells, there are concerns that this may in turn adversely impact the immune reconstitution and longer term outcomes of transplanted patients. However, data on the engraftment characteristics and long‐term post‐transplant outcomes in patients transplanted with plerixafor‐mobilized PBSCs are lacking. This retrospective study examined the post‐transplant outcomes of 105 consecutive adult HL patients, and compared the post‐transplant outcomes of 21 patients who received plerixafor in addition to G‐CSF ± chemotherapy because of poor mobilization with those of 84 patients who mobilized well without plerixafor. Despite collecting significantly lower CD34+ cell doses (median of 3.41 vs. 6.05 × 10⁶/kg, p < 0.0001) than control patients and requiring more collection days, plerixafor‐mobilized patients showed comparable early engraftment characteristics, except for slightly delayed neutrophil engraftment (median: 11 vs.10 days, p = 0.002) and lower median neutrophil counts (2.1 vs. 2.6 × 10⁹/L, p = 0.04) at one month after transplant. No significant differences were observed in longer term post‐transplant outcomes, including cell counts at 3, 6, and 12 months, RBC and platelet transfusion support during the first 120 days, relapse incidence, overall and progression‐free survival rates up to two years post transplant. The use of plerixafor not only enabled poorly mobilizing HL patients to collect enough PBSCs to proceed to ASCT, but also to have similar post‐transplant outcomes compared to patients who mobilized well with conventional regimens.

高剂量化放疗联合自体造血干细胞移植治疗霍奇金淋巴瘤11例报告

背景与目的：高剂量化放疗（high dose chemoradiotherapy,HDT)联合自体造血干细胞移植（autologous hemotopoietic stem cell,ASCT)巳成为复发与耐药霍奇金淋巴瘤（HL）患者重要的解救治疗手段之一,但对于初治晚期患者的作用还不明确。本论文的目的是进一步评价HDT联合ASCT在HL综合治疗中的地位,特别是探讨其对于初治晚期具有明显不良预后因素患者的作用。方法：11例复发和具有不良预后因素的晚期HL患者,其中初始9例,复发2例;自体骨髓移植（autologus bone marrow transplantation,ABMT)1例,自体外周血干细胞移植（autologous peripheral bllod stem cell transplantation,APBSCT)10例。诱导治疗后4例完全缓解（CR）,7例部分缓解（PR）。7例采用高剂量化疗联合全身照射（total body irradiation,TBI)或全淋巴结照射（total lymph node irradiation,TLI)/次全淋巴结照射（subtatal lymph node irradiation,STLI)作用预处理方案,4例采用单纯高剂量化疗作为预处理方案。5例患者于移植后进行了原发部位的补量放疗。结果：移植前达CR者为巩固治疗,达PR后移植后2例达CR,1例达PR,4例稳定（SD）;SD者均为骨受侵。中位随访13（1-84）个月,所有患者全部生存。4例无病生存;4例骨受侵者疾病无进展生存;3例复发,其中1例经复发部位放疗后,目前又无瘤生存42个月,另外2例正进一步治疗中;根据寿命表法分析,全组6年累积疾病无进展生存率（progression-free survival,PTS)为55.68%,6年累积总生存率（OS）为100%;初治患者6年PFS为62.5%。移植相关毒性主要为IV度骨髓抑制,未见明显心、肝、肾毒性,无移植相关死亡。结论：HDT联合ASCT是治疗复发和具有不良预后因素的晚期HL的一种值得进一步探讨的方法。     

High-dose therapy and autologous stem cell transplantation for chemoresistant Hodgkin lymphoma: the Seattle experience

BACKGROUND.: High-dose therapy (HDT) with autologous stem cell transplantation (ASCT) is the standard treatment for patients with chemosensitive relapsed/refractory Hodgkin lymphoma (HL), but this therapy is commonly denied to patients with resistant disease. We explored the utility of HDT and ASCT for chemoresistant HL because there are few established therapies for these patients. METHODS.: Sixty-four chemoresistant HL patients underwent HDT followed by ASCT at our center. Baseline characteristics included median age = 35 years (range, 14-59 years), stage III/IV = 49 (77%), nodular sclerosis histology = 51 (80%), and prior radiation = 32 (50%). Twenty-six patients (41%) received total body irradiation (TBI)-based regimens, and 38 (59%) underwent non-TBI conditioning. RESULTS.: The estimated 5-year overall survival (OS) and progression-free survival (PFS) were 31% and 17%, respectively (median follow-up = 4.2 years). Multivariate analysis only identified year of transplant as independently associated with improved OS (P = .008) and PFS (P = .04), with patients receiving transplants in later years having better outcome. The probabilities of 3-year PFS for patients receiving transplants during 1986 to 1989, 1990 to July 1993, August 1993 to 1999, and 2000 to 2005 were 9%, 21%, 33%, and 31%, respectively. CONCLUSIONS.: These data suggest that HDT and ASCT may result in prolonged remissions and survival for a subset of chemoresistant HL patients, with improved outcomes in patients receiving transplants more recently.

新药时代造血干细胞移植在多发性骨髓瘤治疗中的地位

 与传统化疗相比,自体造血干细胞移植可提高多发性骨髓瘤（MM）患者的缓解率,延长无进展生存期,是治疗MM的一线方案。但近年来,基于新型药物的联合诱导、巩固和维持治疗提高了MM的治疗效果,对自体造血干细胞移植的地位构成了挑战。异基因造血干细胞移植虽然具有治愈MM的潜能,但移植相关死亡率高,患者的总体生存并未获益。而减低剂量预处理异基因移植虽降低了移植相关死亡率,具有一定的移植物抗骨髓瘤作用,但移植物抗宿主病的发生率高。文章总结了MM干细胞移植相关的临床试验结果,旨在定义新药时代造血干细胞移植在MM治疗中的地位。     

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。     

Prolonged survival after second autologous transplantation and lenalidomide maintenance for salvage treatment of myeloma patients at first relapse after prior autograft

Autologous stem cell transplantation (ASCT) as part of the primary therapy in multiple myeloma (MM) is standard practice. In contrast, the role of a second ASCT (ASCT2) and subsequent lenalidomide maintenance for relapsed disease remains unclear. In this study, we analysed 86 consecutive MM patients with a first relapse after prior ASCT receiving either a second ASCT or conventional chemotherapy. After a median follow‐up of 37.7 months since first relapse, 54 (62.8%) patients were still alive and 29 (33.7%) without progression. Sixty‐one (71.0%) patients received ASCT2 and had better progression‐free survival (PFS) (30.2 versus 13.0 mo; P = .0262) and overall survival (OS) rates (129.6 versus 33.5 mo; P = .0003) compared with 25 (29.0%) patients with conventional treatment. Patients relapsing later than 12 months after ASCT1 benefitted from a second ASCT with better PFS2 (P = .0179) and OS2 (P = .0009). Finally, lenalidomide maintenance after ASCT2 was associated with longer PFS (41.0 vs 21.6 mo; P = .0034) and better OS (not yet reached vs 129.6 mo; P = .0434) compared with patients without maintenance. Our data suggest that a second ASCT and lenalidomide maintenance given at first relapse in MM after prior ASCT are associated with better survival rates.     

High-dose therapy and autologous stem-cell transplantation can improve event-free survival for indolent lymphoma: a study using patients as their own controls

BACKGROUND: High-dose therapy (HDT) and autologous stem-cell transplantation (ASCT) remain controversial for indolent lymphoma patients. METHODS: The study was designed to evaluate the benefit of this strategy by retrospectively comparing for each patient the event-free survival (EFS) after ASCT with the duration of the disease phase just before the phase including ASCT (ie, the last qualifying phase, LQP). RESULTS: A total of 109 indolent lymphoma (mostly follicular lymphoma) patients were treated with HDT and ASCT. Before ASCT, patients experienced a median of 2 disease phases (range, 1-4). After a median 5-year follow-up from ASCT, overall survival was 67% and EFS was 43%. When each of the 92 patients experiencing recurrence was taken as her/his own control, EFS was longer after ASCT than the duration of LQP (62%, P < .01). During LQP, 86 patients (93%) experienced recurrence in less than 5 years, compared with only 58 (63%) who experienced recurrence in the 5 years after ASCT (P < .01). CONCLUSION: HDT and ASCT can significantly increase EFS in comparison with the duration of the LQP for indolent lymphoma patients and can change disease course. This methodology has been found useful for evaluating new strategies, especially with monoclonal antibodies.     

Autologous stem cell transplantation for elderly patients with newly diagnosed multiple myeloma in the era of novel agents

BackgroundHigh-dose therapy (HDT) with autologous stem cell transplantation (ASCT) is considered the standard of care for multiple myeloma (MM) patients <65 years. Safety and outcome of ASCT for patients >65 years is currently uncertain, especially since the introduction of novel agents for induction and maintenance therapy. Furthermore, there are no conclusive data available on risk assessment in elderly patients treated with HDT.Patients and methodsWe retrospectively analyzed 202 patients ≥60 years with newly diagnosed MM who underwent ASCT at our institution. Patients were stratified by age into three groups (60–64, 65–69 and 70–75 years). For safety assessment, we compared data about hospitalization, hematopoetic reconstitution and early mortality. Remission before and after ASCT was analyzed according to age and application of novel agents. Event-free (EFS) and overall survival (OS) were analyzed to identify impact of age, remission before/after ASCT and maintenance therapy as well as ISS score and cytogenetic aberrations on outcome in elderly patients.ResultsThe assessment of safety, remission before/after ASCT as well as EFS and OS showed no significant differences between the three groups (median EFS: 60–64 years: 27 months; 65–69 years: 23 months; 70–75 years: 23 months; median OS: not reached). Patients receiving novel agents as part of induction therapy achieved significantly higher nCR + CR rates than patients treated without novel agents. In Cox regression analysis, ISS and cytogenetics as well as remission after ASCT had the highest prognostic impact on EFS and OS. Maintenance therapy was associated with longer EFS in uni- and multivariate analyses.ConclusionASCT is feasible for selected patients >65 and >70 years without increased mortality. Age at transplantation has no prognostic significance on outcome after ASCT. Novel agents during induction therapy and maintenance therapy improves outcome of older patients eligible for ASCT. ISS and cytogenetic analysis should be carried out routinely for risk assessment.     

异基因造血干细胞移植在年轻多发性骨髓瘤患者治疗中的应用

目的探讨异基因造血干细胞移植在年轻多发性骨髓瘤治疗中的疗效及安全性。方法回顾性分析我科2003年4月至2012年6月行清髓异基因造血干细胞移植(allo-SCT）的22例多发性骨髓瘤患者,中位年龄为44.5岁（30～54岁）。所有患者随访至2012年10月。中位随访时间11月（0.9～92月）。结果22例患者移植前完全缓解率为13.6%,移植后完全缓解率达63.6%。100天内移植相关死亡率（TRM）为9.1%。1年内TRM为22.7%。1年内的复发率为13.6%。随访期内总生存率为68.2%,无进展生存率为50%。多因素分析未显示年龄、性别、移植前缓解状态及诊断至移植时长是影响总生存期的独立危险因素。结论清髓的异基因造血干细胞移植用于年轻多发性骨髓瘤患者具有较好的疗效及安全性,且一年内复发率较低。     

自体造血干细胞移植治疗多发性骨髓瘤的疗效及预后影响因素分析

目的:探讨自体造血干细胞移植治疗多发性骨髓瘤（MM）的疗效和影响MM患者预后的因素。方法:回顾性分析我院2012年01月至2019年12月37例接受自体造血干细胞移植的MM患者的临床资料,中位随访时间为55（1～91）个月。对37例患者的反应深度、无进展生存时间（PFS）、总生存时间（OS）和影响预后的相关因素进行分析。结果:移植后3月内疗效达到完全缓解率和深度缓解率均优于移植前（P＜0.01,P＜0.05）,移植前后总有效率（ORR）比较无统计学意义（P＞0.05）。患者3年、5年OS率为97.0%、81.4%;3年、5年PFS率为62.7%、51.0%;中位PFS和OS均未获得。单因素分析结果表明移植后3月内疗效获得深度缓解较未获得患者无论是OS 还是PFS均较优 (P均＜0.01);诱导化疗后获得深度缓解可明显延长OS（P＜0.05）;DS分期Ⅰ-Ⅱ期、mSMART3.0危险分层标危患者相比DS分期Ⅲ期、高危患者PFS均有明显优势(P＜0.05)。Cox 多因素回归分析显示,移植后3月内疗效达深度缓解是PFS和OS的独立预后因素,mSMART3.0危险分层也是PFS的独立预后因素。结论:自体造血干细胞移植可以提高 MM 患者的反应深度。移植前后疗效、DS分期和mSMART3.0危险分层均可影响MM患者生存率。移植后3月内疗效达深度缓解是PFS 和OS的独立预后因素,mSMART3.0危险分层也是PFS的独立预后因素。     

High-dose therapy/autologous hematopoietic stem cell transplantation in relapsed or refractory marginal zone non-Hodgkin lymphoma

The optimal therapy for patients who have relapsed or refractory marginal zone lymphoma has not been defined. We analyzed the clinical outcomes of 14 patients who had relapsed or refractory marginal zone lymphomas and underwent high-dose therapy/autologous hematopoietic stem cell transplantation (HDT/AHSCT) at the University of Nebraska from August 1992 to August 2008. The median age of patients was 48 years (range, 29 to 62 years). All patients had relapsed or refractory disease. There were three treatment-related deaths within 100 days of transplantation. With a median follow-up of 138 months, the median duration of failure-free survival is 108 months, and the median duration overall survival is 120 months. Only two patients have relapsed. Secondary malignancies were seen in three patients (myelodysplastic syndrome, n = 2; gastric carcinoma. n = 1). We conclude that HDT/AHSCT is feasible in patients who have relapsed/refractory marginal zone lymphomas. Approximately one- third of patients can achieve long-term disease-free survival.     

Autologous stem cell transplantation for patients with active Hodgkin's lymphoma: long-term outcome of 61 patients from a single institution

Sixty-one patients with refractory or relapsed Hodgkin's lymphoma (HL) underwent high-dose chemotherapy and autologous stem cell transplantation (ASCT). All patients had active HL at the time of ASCT: 13 patients had partial remission, 14 refractory disease, 18 sensitive relapse, 4 resistant relapse, and 12 nontreated relapse. Overall transplant-related mortality (TRM) was 16.4% at 1 year. Twenty-eight patients (46%) achieved complete remission (CR). Actuarial 5-year overall survival (OS) and progression-free survival (PFS) were 51% and 47%, respectively. Patients with positive gallium-67 scintigraphy at 3 - 6 months after transplantation had a worse PFS at 5 years (28%) than those with negative 67Ga scan (80%) (p = 0.016), whereas no statistical differences were observed between patients with residual mass and those in CR according to computed tomography scan. In multivariate analysis, bulky disease at diagnosis, bone marrow stem cells, and stage IV at transplant were the only adverse prognostic factors significantly influencing OS. Bulky disease at diagnosis and stage IV at transplant adversely influenced PFS. Although long-term outcome of patients with active HL at the time of ASCT is poor due to a high TRM and a low CR after transplantation, a subgroup of patients with no adverse prognostic factors at ASCT gain benefit from this treatment.     

Adequate Engraftment With Lower Hematopoietic Stem Cell Dose

BackgroundAdequate hematopoietic stem cell dose is required to proceed with autologous stem cell transplantation (ASCT).Patients and MethodsWe conducted a retrospective analysis of 108 patients with multiple myeloma and lymphoma who underwent ASCT with noncryopreserved stem cells at our center. Data were compared for patients who received stem cell dose < 2 × 10⁶/kg with those who received a higher dose.ResultsThe median CD34 dose collected in the lesser dose group was 1.76 × 10⁶/kg (1.22 to 1.97 × 10⁶/kg). Mean CD34 dose of the whole group was 4.96 ± 4.2 × 10⁶/kg. Neutrophil engraftment was similar in both groups (12 vs. 11 days) (P = .065). Similarly, platelet engraftment occurred in 12 versus 11 days in both groups (P = .017). Length of hospital stay was similar in both groups. There was no significant difference in the incidence of proven bacterial infections between the 2 groups. There was no transplant-related mortality in lower dose group.ConclusionASCT can be safely performed with lower hematopoietic stem cell dose in noncryopreserved setting.
