造血干细胞移植治疗多发性骨髓瘤的研究进展

 【摘要】　造血干细胞移植（HSCT）是治疗多发性骨髓瘤（MM）的一线方案。自体造血干细胞移植（auto-HSCT）可提高患者缓解率,延长生存期。首次auto-HSCT后,未获得非常好的部分缓解及以上疗效的患者,可行二次auto-HSCT进一步改善疗效。异基因造血干细胞移植（allo-HSCT）具有治愈MM的潜能,但移植相关死亡率高,患者生存并未获益。减低剂量的allo-HSCT相关死亡率低,但复发率高,也未显示出生存优势。序贯auto-HSCT及allo-HSCT也未使患者生存明显获益。总结近期HSCT的研究进展。     

血管免疫母细胞性T细胞淋巴瘤治疗研究进展

血管免疫母细胞性T细胞淋巴瘤(AITL)是一种系统性、侵袭性外周T细胞淋巴瘤,目前仍然缺乏标准治疗方案.联合化疗没有明显改善预后且缓解持续时间短;靶向药物和免疫抑制治疗研究样本小,不能明确疗效;大剂量化疗联合自体造血干细胞移植(HDT-ASCT)和异基因造血干细胞移植(allo-HSCT)虽然都取得了显著疗效,但HDT-ASCT具有高复发率、远期继发肿瘤等诸多风险,allo-HSCT亦因移植相关死亡率较高而有待进一步探讨.文章就近年来AITL的治疗研究进展加以综述.

自体或异体间充质干细胞移植对造血重建的影响

目的 初步探讨自体或异体间充质干细胞(MSC)移植对造血重建的影响.方法 采用含血清培养体系培养扩增自体或供者骨髓以及来自胚胎的MSC,例1为系统性红斑狼疮(SLE);例2为非霍奇金淋巴瘤(NHL),患者在造血干细胞移植(HSCT)前先输注自体MSC,然后进行自体HSCT;例3为阵发性睡眠性血红蛋白尿(PNH),在HSCT前先输注供者MSC,然后进行同基因异体HSCT;例4为慢性粒细胞白血病(CML),行异基因HSCT;例5为淋巴瘤行自体HSCT,在移植后造血恢复缓慢(分别为+129天,+78天)移植来自胚胎的MSC.结果 例1、例2和例3患者MSC和HSCT联合无明显不良反应.中性粒细胞≥0.5×109/L和血小板≥20×109/L的时间分别为移植后1、10、10和1、8、33 d.粒细胞缺乏时间分别为0、7、12 d;输注来自胚胎MSC的患者(例4、例5),1个月内造血仍无恢复,MSC移植失败.结论 MSC移植时机掌握很重要,与HSCT同时进行,可以促进造血重建,而在移植后一些造血重建缓慢的患者再进行MSC移植的疗效还有待进一步研究.

Abstract：

Objective To investigate the impact of auto and allogenic mesenchymal stem cells (MSC) transplantation on hematopoietic reconstitution. Methods MSC from auto, donor bone marrow or embryonic tissue were cultured and expanded in vitro in the serum culture system. Five patients received hematopoietic stem cell transplantation (HSCT) were investigated. Case 1 of systemic lupus erythematosus and Case 2 of non-hodgkin' s lymphoma (NHL) received auto MSC transplant before auto-HSCT. Case 3 of paroxysmal nocturnal hemoglobinuria received HLA-identical allogenic MSC transplant before HLA-identical allo-HSCT.Case 4 of chronic myelocytic leukemia and Case 5 of NHL had delayed hematopoietic reconstitution (129th and 78th day, respectively) after allo- and auto-HSCT, respectively, and received MSC from embryonic tissue.Results Case 1, 2 and 3 had no manifested side effects after MSC transplantation combined with HSCT.Neutrophil count of case 1, 2, and 3 were over 0.5 ×109/L at 1st, 10th and 10th day, respectively, platelet count were over 20 ×109/L at 1st, 8th and 33th day, respectively, and agranulocytosis at Ost, 7th and 12th day, respectively. The treatment of embryonic tissue MSC transplant was confirmed to fail for Case 4 and 5.Conclusion The time of MSC transplant has a great impact on hematopoietic reconstitution. MSC transplantation and HSCT performed simultaneously can improve hematopoietic reconstitution. However, the impact of MSC on patients with delayed hematopoietic reconstitution after HSCT needs further study.     

异基因造血干细胞移植在复发难治淋巴瘤中的应用

复发难治淋巴瘤的治疗仍然是临床上的一大难题,目前主要以大剂量化疗联合自体造血干细胞移植及新药、细胞免疫治疗为主。近年减低强度预处理方案异基因造血干细胞移植（allo-HSCT）及替代供者的应用,使allo-HSCT成为复发难治淋巴瘤有价值的治疗选择。疾病特征、患者临床特点、替代供者的选择、预处理强度及移植相关并发症的管理等因素均影响着患者移植后的生存。allo-HSCT治疗复发难治淋巴瘤的数据主要来源于各移植中心的回顾性报道,前瞻性试验仍缺乏,移植患者的选择及移植时机的把握、移植物来源、预处理强度的选择等仍无统一的标准。文章将围绕这些方面对allo-HSCT在复发难治淋巴瘤中的应用进展进行介绍。

Low incidence of posttransplant lymphoproliferative disorder after allogeneic stem cell transplantation in patients with lymphoma treated with rituximab

Posttransplant lymphoproliferative disorder (PTLD) is a serious complication after hematopoietic stem cell transplantation (HSCT). Several studies of risk factors for PTLD have been reported; however, the probability of, and risk factors for, PTLD in patients with lymphoma is unknown. Japanese nationwide transplant registry data from 5270 patients with lymphoma after allogeneic HSCT were analyzed. Mature B-cell, T/NK-cell, and T-cell lymphoblastic subtypes accounted for 49%, 26%, and 9.6% of lymphoma cases, respectively. Rituximab was used in 1678 lymphoma patients, most of whom (89%) received HSCT for mature B-cell lymphoma. Thirty-one patients with lymphoma developed PTLD, representing a probability of 0.77% at 2 years post-HSCT, which did not differ significantly from that in patients with other diseases (P = .98). Year of HSCT after 2010 (hazard ratio [HR] = 5.6, 95% confidence interval [CI], 1.48-21.3), antithymocyte globulin (ATG) use in the conditioning regimen (HR = 4.5, 95% CI, 1.61-12.5), and no rituximab use before HSCT (HR = 3.2, 95% CI, 1.26-7.90) were identified as risk factors for PTLD. Probabilities of PTLD at 1 year post-HSCT according to rituximab and ATG use were 0.23% (rituximab+, ATG−), 0.75% (rituximab−, ATG−), 1.25% (rituximab+, ATG+), and 3.53% (rituximab−, ATG+). Regarding lymphoma subtypes, patients with mature B-cell lymphoma had the lowest incidence of PTLD (0.35% at 2 years). Among high-risk patients receiving ATG, the mortality rate due to infection was elevated in those previously treated with rituximab (22%) relative to those without (14%); however, the difference was not significant (P = .10). Rituximab use before HSCT significantly reduces the risk of PTLD. Adding rituximab to the conditioning regimen is potentially a good strategy to prevent the development of PTLD in high-risk patients.     

Reduced-Intensity Allogeneic Stem Cell Transplantation for Co-Emergence of Chemotherapy-Refractory Follicular Lymphoma and Therapy-Related Myelodysplastic Syndrome

A 54-year-old male was diagnosed with follicular lymphoma in September 2003. Despite multiple chemotherapies, including autologous hematopoietic stem cell transplantation (HSCT) with high-dose chemotherapy, the disease eventually relapsed. Additionally, bone marrow analysis revealed the co-emergence of therapy-related myelodysplastic syndrome (t-MDS) in February 2012. In March 2012, we performed related allogeneic HSCT for the treatment of both malignancies. This strategy was successful and the patient has remained free from both malignancies for 23 months. Allogeneic HSCT is a potent curative therapeutic option for both t-MDS and refractory follicular lymphoma.Key words: Therapy-related myelodysplastic syndrome, Follicular lymphoma, Allogeneic transplantation     

造血干细胞移植治疗外周T细胞淋巴瘤的进展

The general chemotherapy for Peripheral T-cell lymphoma(PTCL) featuring an active invasion has less curative effect and worse prognosis in comparison with that for B-cell non-Hodgkin's lymphoma(NHL).Studies in recent years suggest that hematopoietic stem cell transplantation(HSCT) has better curative effect on the PTCL;however,it is significant to do more studies on some aspects such as the methodology,punctuality,preconditioning,and pretreatment intensity of the transplantation,which are crucial to the cur...     

Prognostic Factors for the Long-Term Survival after Hematopoietic Stem Cell Transplantation in Patients with Hodgkin Lymphoma

Objectives: This study investigated the possible prognostic factors for the long-term survival (Cure Rate) of Hodgkin Lymphoma patients who underwent HSCT. Methods: This retrospective cohort study analyzed 116 Patients diagnosed with Hodgkin Lymphoma who received autologous hematopoietic stem cell transplantation (Auto-HSCT) between the years 2007 and 2014 and followed up until 2017. The information regarding patients’ survival had been collected using phone calls, and their pre-transplant information was available in the archived documents. Prognostic effects were investigated using long-term survival models. Results: Patients with obesity had five times higher odds of long-term survival (cure) than the others (P=0.06). Also, the recurrence experience after HSCT negatively impacted the curing potential by 78% (P=0.05). Also, with 32 years as the change point, patients younger than 32 had 76% fewer odds of surviving long-term (P=0.03), and Poor transfused stem cell dose of CD34+ (<0.16 × 106 cells/ml) reduced the odds of long-term survival by 92% (P=0.01). Conclusion: According to the statistical models used in this study, obesity can increase the curing potential of Hodgkin lymphoma after transplantation. Meanwhile, aging, poor transfused CD34+ cells, and recurrence after HSCT were associated with lower survival following HSCT.     

The allogeneic effect in non-Hodgkin's lymphoma

Allogeneic hematopoietic stem cell transplantation (HSCT) has been restricted to medically fit patients under the age of 55 years due to adverse effects of the intensive conditioning regimens. Autologous HSCT has not proven to be a particularly effective treatment for patients with low-grade non-Hodgkin's lymphoma (NHL). Much of the benefit of allogeneic HSCT appears to be mediated by a graft-vs.-tumor (GVT) effect. Reduced-intensity regimens in allogeneic HSCT have been developed to minimize conditioning regimen-related toxicities and to control the malignancy until a GVT effect is established. A number of studies investigating reduced-intensity allogeneic HSCT are discussed. Results from these studies suggest that indications for allogeneic transplant include patients with low-grade NHL with a sibling or matched donor who are under 60 years of age; young patients with mantle cell lymphoma who are in first remission and have a sibling or matched donor; patients with high-grade NHL who have already failed an autograft but have chemosensitive disease, and those under 30 years of age who have poor-risk disease and are in first remission. It is concluded that reduction in treatment-related mortality with reduced-intensity HSCT and the presence of GVT effects increases the applicability of allogeneic transplantation for NHL. However, treatment will be improved by optimizating conditioning regimens and a better understanding of patient selection criteria and the immune processes involved in graft-vs.-host disease and GVT.     

Recent progress in the treatment of malignant lymphoma

The present state of the art and developments in the treatment for Hodgkin's disease (HD), follicular lymphoma (FL), MALT lymphoma, and aggressive non-Hodgkin's lymphoma are reviewed. Four courses of ABVD therapy (ABVd therapy in Japan) followed by involved-field irradiation (IFRT), and 6 to 8 courses of ABVD (ABVd in Japan) are the current state art of the therapy for early stage HD and advanced stage HD, respectively. High-dose chemotherapy with autologous hematopoietic stem cell transplantation (auto-HSCT) is also the state of the art for refractory or relapsed HD within 1 year after complete remission (CR) produced by polychemotherapy. The prognosis of the patients with 3 or more International Prognostic Scores (IPS) is poor. New intensified polychemotherapy or auto-HSCT as up-front setting is under randomized phase III clinical trial in Europe and the USA. There is no state of the art therapy for indolent lymphoma including FL, or MALT. Promising results were reported from clinical studies using new anti-lymphoma drugs such as rituximab, iibritumomab, or purine analogs (cladribine and fludarabine), and auto-HSCT with effectively purged stem cells or allogeneic HSCT. These therapeutic strategies hold a possibility of cure for indolent lymphomas. Antibiotic treatment for Helicobacter pylori-positive localized gastric MALT lymphoma is the state of the art therapy. However, there is no standard therapy for advanced stage MALT lymphoma. Risk adapted therapy using the International Prognostic Index is essential for the treatment of aggressive NHL. Three courses of CHOP followed by IFRT for localized aggressive NHL and 8 courses of CHOP for the low-risk group of advanced stage aggressive NHL are the state of the art therapies, respectively. High-dose chemotherapy with auto-HSCT is also the state of the art for sensitive relapse patients with aggressive NHL. Although some clinical studies suggested that high-dose chemotherapy with auto-HSCT as up-front setting for high-intermediate or high-risk group aggressive NHL is more effective than conventional chemotherapy, the efficacy remains to be determined. The development of new therapeutic strategies with combined use of molecular targeting drugs such as rituximab, or new anti-lymphoma drugs such as purine analogs, and HSCT is desired for more effective therapy for refractory lymphomas.     

How to predict the outcome in mature T and NK cell lymphoma by currently used prognostic models?

To select an appropriate prognostic model in the treatment of mature T- and natural killer (NK) -cell lymphoma (peripheral T-cell lymphoma (PTCL) and NK-/T-cell lymphoma (NKTCL)) is crucial. This study investigated the usefulness of Ann Arbor staging classification International prognostic index (IPI), prognostic index for T-cell lymphoma (PIT) and International peripheral T-cell lymphoma Project score (IPTCLP). Between 2000 and 2009, 176 patients (122 males) with PTCL and NKTCL were diagnosed and treated from a single institute in Taiwan. The correlation between complete response (CR) rate, 3-year overall survival (OS), early mortality rate and four prognostic models was analyzed. Thirty-one patients received hematopoietic stem cell transplantation (HSCT) and were analyzed separately. Three-year OS rate was 34.7%, and anaplastic large-cell lymphoma harbored better outcome than others. IPI score had the lowest Akaike information criterion value (1081.197) and was the best score in predicting OS and early mortality (P=0.009). Ann Arbor stage classification can predict CR rate more precisely (P=0.006). OS was significantly better in patients who received HSCT, even in patients with unfavorable features compared with chemotherapy alone. All prognostic models were useful to evaluate the outcome of patients with PTCL and NKTCL but IPI score did best in predicting OS in PTCL and PIT score in NKTCL. This study also supported the role of HSCT in patients with high-risk or refractory PTCL or NKTCL.
