T淋巴母细胞淋巴瘤自体干细胞移植后的长期随访观察 总被引:1,自引:0,他引:1
目的评价自体造血干细胞移植(autologous hematopoietic stem cell transplantation,AHSCT)治疗复发难治T淋巴母细胞淋巴瘤(TLBL)的临床疗效及安全性。方法本文回顾性分析AHSCT治疗后长期随访的TLBL16例,预处理方案主要为BEAM和BEAC。结果 15例患者可评价疗效,1例失访。中位随访37个月(12~132个月),中位无进展生存时间(PFS)34.5个月。预计中位总生存时间49月。1、3、5年总生存率分别为60%、53%、32%。初治患者一线治疗有效者,接受AHSCT者预计中位总生存时间为108个月,5年总生存率、无进展生存率分别为62%、63%;复发患者挽救治疗后接受AHSCT者,中位总生存时间为22.8个月,5年总生存率、无进展生存率分别为33%、22%。初始治疗未达CR/PR的难治患者,中位生存仅21个月,5年生存率和无进展生存率分别为20%和29%。结论 AHSCT常规化疗治疗TLBL安全、有效,可提高复发难治的T淋巴母细胞淋巴瘤的远期生存,延长初治TLBL患者的无进展生存期,但复发率仍偏高,值得开展大规模临床试验进一步深入研究。 相似文献

目的:探讨单纯Hyper-CVAD 方案与Hyper-CVAD 方案联合自体造血干细胞移植一线巩固治疗淋巴母细胞淋巴瘤(lymphoblastic lymphoma ,LL)的疗效。方法:回顾性分析26例青少年和成人初治采用改良Hyper-CVAD 方案的LL患者资料。其中,22例不伴骨髓受侵的患者中,11例接受单纯改良Hyper-CVAD 方案治疗,另外11例接受改良Hyper-CVAD 方案联合HDT/AHSCT 巩固治疗。结果:全组61.5%(16/26)的患者初治达完全缓解(complete remission ,CR)或不确定的CR(unconfirmedCR,CRu ),中位随访29.5 个月,5 年的总生存(overall survival,OS)率和无进展生存(progress-free survival ,PFS)率分别为66.8% 和50.2% 。22例无骨髓受侵的患者中,单纯Hyper-CVAD 组与联合HDT/AHSCT组的5 年OS率分别为60.0% 和70.7%(P=0.438),5 年PFS 率分别为43.6% 和62.3%(P=0.209),均无统计学差异。单因素预后分析结果显示,初治缓解后1 年内疾病进展或复发与预后不良相关(P=0.012)。 结论:改良Hyper-CVAD 方案是青少年和成人LL一线有效的治疗方案。对于无骨髓侵犯的患者,单纯改良HyperCVAD 已能取得较好疗效,联合HDT/AHSCT巩固治疗未能进一步改善预后。 相似文献

大剂量化疗联合自体造血干细胞移植(HDT-ASCT)是目前治疗复发难治的弥漫大B细胞淋巴瘤的标准方案,但其在滤泡性淋巴瘤、套细胞淋巴瘤及外周T细胞淋巴瘤治疗上的作用及地位存在争议。根据2010年NCCN非霍奇金淋巴瘤治疗指南建议,HDT-ASCT仍是治疗复发滤泡性淋巴瘤、初治套细胞淋巴瘤及外周T细胞淋巴瘤的重要方法,但需大规模的前瞻性临床试验证实其作用及验证不同类型淋巴瘤最佳的诱导、动员及维持治疗方案。对于HDT-ASCT在霍奇金淋巴瘤中的应用有很多问题需要解决,如预处理方案的选择、自体造血干细胞移植前的最佳化疗周期数、放疗在HDT-ASCT中的应用及二重癌发生的风险等。现就ASCT近年来的研究进展作一综述。 相似文献

目的 探讨单纯CHOP样方案与CHOP样方案+高剂量治疗联合造血干细胞移植(HDT-HSCT)一线巩固治疗淋巴母细胞淋巴瘤(LBL)的疗效.方法 63例有完整治疗及随访记录的LBL患者,初治均采用标准CHOP样方案,42例获得完全缓解(CR)或不确定CR(CRu).其中26例接受HDT-HSCT巩固治疗,16例单纯进行6~8个周期CHOP样方案治疗.结果 63例患者中,初治总缓解率为82.5%.中位随访24个月时,5年生存率为31.2%,5年无病生存率为29.3%.接受HDT-HSCT巩固治疗的26例患者,5年生存率为59.8%;单纯CHOP样方案治疗的16例患者,5年生存率为14.6%,差异有统计学意义(P=0.004).单因素预后分析结果显示,年龄、骨髓侵犯、初治缓解情况与预后有关(均P<0.05).18例骨髓受侵的患者中,3例接受异基因造血干细胞移植(allo-HSCT)的患者在随访22、32和37个月时仍生存,而4例接受自体造血干细胞移植(auto-HSCT)的患者,均在14个月内死亡.结论 单纯应用CHOP样方案治疗LBL疗效欠佳.HDT-HSCT作为一线巩固治疗有可能提高LBL患者的总生存率和无病生存率.骨髓受侵的LBL患者,allo-HSCT的效果优于auto-HSCT. 相似文献

IntroductionDuring the past decade, interstitial pneumonia (IP) is one of the newly recognized adverse events regarding rituximab therapy. However, disease characteristics of IP after autologous hematopoietic stem cell transplantation (ASCT) have not been well-described since the introduction of rituximab.Patients and MethodsWe retrospectively analyzed 103 patients with B-cell non-Hodgkin lymphoma undergoing ASCT. A propensity scoring system was applied in our analysis to eliminate potential confounding factors of covariates.ResultsThe total number of patients who developed IP was nine. Five patients developed IP among 57 patients previously treated with rituximab, and four patients developed IP among 46 who were rituximab-naïve. Cumulative incidence of IP was 7.8% at 1 year. Among the patients using rituximab, one patient had IP during the peri-engraftment period (cytomegalovirus infection), three patients had IP between 3 and 12 months (Pneumocystis pneumonia [PCP, n = 1] and unknown cause [n = 2]), and the other one patient had IP 3.3 years after ASCT (unknown cause). Four patients in the rituximab-naïve group developed IP between 3 and 12 months (PCP [n = 1] and unknown cause [n = 3]). All nine patients had symptomatic episodes before IP, three of which died of IP or secondary infections. Patients receiving a total body irradiation conditioning regimen had a higher risk of IP (odds ratio = 3.6, P < .001), whereas the incidence was not affected by rituximab usage (P = .85, Log-rank test).ConclusionThis study shows that the rituximab usage was not identified as a risk factor of IP and that total body irradiation was the only independent risk factor for IP. Close monitoring is encouraged when symptomatic unexplained episodes are identified during follow-up examinations after ASCT. 相似文献

BackgroundHigh-dose therapy and autologous stem cell transplantation (ASCT) improves outcomes for patients with mantle cell lymphoma (MCL), but relapse ultimately occurs in most patients. Recently presented interim results from a phase III prospective trial suggest maintenance rituximab (MR) after ASCT for MCL improves progression-free survival (PFS). The maturation of these data and any benefit of MR on overall survival (OS) remain to be defined.Patients and methodsIn this retrospective study, we examined a cohort of consecutive patients with MCL that underwent ASCT for MCL at our center and evaluated their outcomes according to whether they received MR after ASCT (n = 50) or did not (n = 107). MR was treated as a time-dependent covariate to account for variation in timing of its initiation.ResultsMR was associated with an improved PFS [hazard ratio (HR) 0.44; confidence interval (CI) (0.24–0.80), P = 0.007] and overall survival (OS; HR 0.46; CI 0.23–0.93, P = 0.03) following a multivariate adjustment for confounding factors with a median follow-up of ∼5 years. Grade 4 neutropenia was increased (34% versus 18%, P = 0.04) in the MR group, but no effect on the rate of mortality unrelated to relapse was observed.ConclusionsThese data support that MR after ASCT for MCL confers a benefit in PFS and additionally suggest it may improve OS. General application of this strategy will require confirmation of benefit in prospective randomized trials. 相似文献

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. 相似文献
