目的 评价Hyper-CVAD化疗方案治疗侵袭性T细胞淋巴瘤的效果和安全性.方法 对2009年9月至2010年12月在北京协和医院接受Hyper-CVAD方案诱导化疗的34例初诊侵袭性T细胞淋巴瘤患者的疗效和不良反应等资料进行回顾性分析,并进行生存分析.结果 34例患者接受Hyper-CVAD方案诱导化疗后,28例(82.4%)有治疗反应,其中10例(29.4%)获得完全缓解(CR);11例接受造血干细胞移植(包括1例同胞全合异基因造血干细胞移植).中位随访时间16个月(1~82个月),1、3年总生存(OS)率分别为70.2%、41.1%;1、3年无进展生存(PFS)率分别为49.3%、31.6%.化疗不良反应主要为骨髓抑制,18例(52.9%)发生Ⅳ级骨髓抑制;3例因严重感染死亡.Cox多因素分析显示,化疗能否达到CR是PFS的独立影响因素(HR=6.118,95%CI 1.327~28.206,P=0.020);骨髓是否受累(HR=0.270,95%CI 0.101~0.722,P=0.009)和化疗能否达到CR(HR=6.669,95%CI 1.754~25.354,P=0.005)是OS的独立影响因素.结论 Hyper-CVAD方案诱导化疗治疗侵袭性T细胞淋巴瘤的反应率高,但有效持续时间短,远期疗效不佳,同时骨髓抑制严重,感染发生率高.缓解后行自体造血干细胞移植可能提高侵袭性T细胞淋巴瘤的疗效.  相似文献

背景与目的:弥漫大B细胞淋巴瘤(diffuse large B cell lymphoma,DLBCL)根据基因表达可以分成有两种不同预后的亚型:生发中心B细胞样亚型(germinal centre B-cell lymphoma,GCB)和活化B细胞样亚型(non-germinal centre B-cell lymphoma,non-GCB).本文分析原发于淋巴结内DLBCL的临床特征、免疫亚型及预后,并探讨有效的治疗方法.方法:收集本院2003年-2009年诊治的70例结内DLBCL.分析其临床资料和IPI评分,用免疫组织化学染色分成GCB和non-GCB两类免疫亚型.治疗方法包括CHOP化疗及利妥昔单抗联合CHOP (R-CHOP)免疫化疗.用Kaplan-Meier法、log-rank检验和Cox回归模型对其临床资料、免疫亚型和治疗结果进行生存分析及单因素和多因素预后分析.结果:全组患者的5年生存期(overall survival,OS)为67.8%.其中CHOP化疗患者的5年OS为58.9%,R-CHOP免疫化疗患者为77.2%,免疫化疗明显优于单纯化疗(P=O.017).免疫亚型为GCB型患者5年OS为73%,non-GCB型患者为55.9%,两者差异无统计学意义(P=0.13).但进一步分析:用CHOP化疗的non-GCB型患者5年OS明显低于GCB型患者(43.5% vs 66.8%,P=0.042);而用R-CHOP免疫化疗的non-GCB型患者5年OS与GCB型患者差异无统计学意义(67.5% vs 80.4%,P=0.717).在nonGCB亚型中,R-CHOP免疫化疗5年OS明显优于CHOP化疗(73.3% vs 42.9%,P=0.02),提示R-CHOP免疫化疗能明显延长non-GCB亚型患者的长期生存.各临床因素与OS的关系:单因素分析表明年龄≥60岁、Ⅲ期、血清LDH升高、B症状和IPI≥3分均是预后不良的因素(P<0.05).Cox多因素回归模型分析结果显示,IPI评分对OS的影响有统计学意义(P<0.01),是独立的预后因素.结论:IPI可以预测结内DLBCL的预后和生存.采用免疫组化对DLBCL免疫分型对指导治疗有一定意义.R-CHOP免疫化疗能够显著提高结内DLBCL患者的长期生存率.  相似文献

非霍奇金淋巴瘤(non-hodgkin lymphoma,NHL)是一组起源于包括B-细胞、T细胞及NK细胞的异质性淋巴增殖性疾病.欧美国家B细胞淋巴瘤(B-NHL)约占80% ~85%[1].我国B细胞淋巴瘤发生率约占NHL的61.6%~74.2%[24].B-NHL包括弥漫大B细胞淋巴瘤、套细胞淋巴瘤、滤泡性淋巴瘤等.NHL的治疗包括化疗、放疗、免疫治疗、放射免疫治疗及造血干细胞移植.近10多年来,由于CD20单克隆抗体(单抗)的应用和自体造血干细胞移植(autologous stem cell transplantation,ASCT)作为巩固治疗使得B-NHL的疗效明显提高[5-6].然而,自体造血干细胞移植是作为该病一线巩固还是待疾病复发后作为挽救性治疗仍待进一步明确.  相似文献

While various tools such as the International Prognostic Index (IPI) and its derivatives exist for risk-stratification of diffuse large B-cell lymphoma (DLBCL) at diagnosis, patient and disease characteristics capable of predicting outcome after high-dose chemotherapy followed by autologous stem cell transplantation (HDC/ASCT) are not clearly defined. We retrospectively analyzed medical records of 111 DLBCL patients (78 relapsed and 33 refractory) who underwent HDC/ASCT at our institution from 2010-2015. After a median follow-up time of 4.6 years (interquartile range [IQR] 2.2-8.1), the likelihood of 5-year progression-free survival (PFS) was 62.2% (95% CI, 53.4%-72.4%) and the likelihood of 5-year overall survival (OS) was 68.9% (95% CI, 60.7%-78.2%). More than three chemotherapy regimens prior to ASCT was the only variable associated with lower likelihood of PFS (P = .004) and OS (P = 0.026). Male gender and high IPI score at time of ASCT were also associated with lower likelihood of PFS (P = .043; P = .013). NCCN IPI and age-adjusted IPI at time of ASCT were not predictive of outcome following ASCT. Patients with refractory and relapsed disease had similar outcomes post-ASCT (P = .207 for PFS, P = .073 for OS).  相似文献

PURPOSE: To determine the treatment outcome and clinical factors that are of prognostic significance for children and adolescents with relapsed or refractory Hodgkin's disease (HD) who received treatment with high-dose chemotherapy and autologous hematopoietic stem-cell transplantation (HSCT). PATIENTS AND METHODS: Fifty-three consecutive children and adolescents 21 years of age or younger with relapsed or refractory HD underwent HSCT. RESULTS: At day 100 after transplantation, 29 patients (55%) were in a complete remission or maintained a continuous complete response, six (11%) had a partial response, and 11 (21%) failed to respond or had progressive disease. The failure-free survival (FFS) at 5 years was 31%, and overall survival was 43%. Twenty-one patients died of progressive HD, and nine died secondary to transplantation-related complications, including two secondary leukemias. Prognostic factors important for FFS were normal pretransplantation lactate dehydrogenase levels (5-year FFS = 42%), compared with patients with elevated LDH levels (5-year FFS = 0%) (P < .001), and disease sensitivity at the time of HSCT with FFS in untreated relapse, sensitive disease, and resistant disease 44%, 35%, and 9%, respectively (P = .06). There was no statistically significant difference in FFS or overall survival between age subgroups that were analyzed (< 13, 13 to 18, 19 to 21) or in comparison with an adult cohort. CONCLUSION: HSCT is an effective treatment modality that can result in long-term cures and should be considered for children and adolescents with relapsed HD.  相似文献

Abstract

We report the outcomes of 45 patients with relapsed or refractory aggressive non-Hodgkin's lymphoma (NHL) treated with a combination of ifosfamide, carboplatinum and etoposide (ICE) and 28 patients treated with a combination of ifosfamide, methotrexate and etoposide (IMVP) during two 5-year periods. The response rate (RR) to ICE was 47%, 2-year overall survival (OS) 31% and 2-year event-free survival (EFS) 22%. These results were similar to those obtained with IMVP (RR 39%, 2-year OS 23%, 2-year EFS 13%; p=0.355 for RR, 0.275 for OS, 0.668 for EFS). Higher IPI scores and refractoriness to treatment were negative prognostic factors, immunophenotype (B vs. T) had no influence on prognosis. Changing from IMVP to ICE does not substantially improve the outcome of patients with relapsed or refractory aggressive NHL. Patients with relapsed/refractory aggressive B-NHL do not have a superior out-come in comparison to those with T-NHL if treated with chemotherapy alone.  相似文献

Between January 1990 and April 2001, 115 patients received high-dose chemotherapy (HDT) followed by autologous stem cell transplantation (ASCT) for relapsed or refractory Hodgkin lymphoma (HL). With a median follow-up of 58 months (range, 1 - 175 months), 5-year progression-free survival (PFS) and overall survival (OS) were 46% and 58%, respectively. Twelve patients with primary refractory disease had a 5-year PFS of 41% and OS of 58%, not significantly different from those of the remaining cohort. Early and overall regimen related mortality were 7% and 16%, respectively. Male gender (P = 0.04) and a time to relapse (TTR) < 12 months (P = 0.03) were associated with decreased OS by univariate analysis. In multivariate analysis, TTR < 12 months remained statistically significant (P = 0.04). We have confirmed that HDT and ASCT result in long-term survival for a proportion of patients with relapsed or refractory HL. All patients, including those with primary refractory disease, benefited from HDT and ASCT.  相似文献

BackgroundPatients with diffuse large B-cell lymphoma (DLBCL) who are not cured by initial therapy sometimes experience disease-free survival after autologous stem cell transplantation. Chemotherapy responsiveness before transplantation is a major predictor of outcome. Patients not responding to second-line regimens may receive third-line therapy in the hopes of achieving response, but outcome data are limited.Patients and MethodsWe identified patients with relapsed or refractory DLBCL at Weill Cornell Medical Center for whom data on responses to second-line chemotherapy were available.ResultsA total of 74 patients with relapsed or refractory DLBCL who underwent second-line chemotherapy between 1996 and 2007 were identified. Of these patients, 27 (36%) did not respond. The median overall survival of nonresponding patients was 4 months, and only 1 patient (4%) survived for 1 year. The choice of third-line aggressive chemotherapy instead of less intensive approaches did not confer a survival benefit.ConclusionOur data demonstrate that patients with recurrent DLBCL not responding to second-line chemotherapy demonstrate dismal outcomes. Trials of novel regimens should be prioritized as management strategies for these patients. Our data provide an important benchmark in the evaluation of the potential clinical value of such approaches.  相似文献

Background: Dose intensification and autologous stem cell transplantation as front-line therapy in non-Hodgkin's lymphoma patients (NHL) is a matter for debate, although preliminary data suggest a role for it in patients at high risk of resistance or relapse according to the international prognostic index (IPI).Purpose and study design: To compare retrospectively the clinical outcome of two cohorts of NHL patients with high-risk IPI treated with MACOP-B for 12 weeks (38 patients) or high-dose chemotherapy (44 patients) including eight weeks of MACOP-B, one or two intensification cycles with mitoxanthrone, dexamethasone, high-dose ara-C and finally BEAM chemotherapy with autologous hemopoietic progenitor cell transplantation.Results: The actuarial estimate of event (progression, relapse or death)-free survival (EFS) at three years was better (58% vs. 41%, P = 0.08) for patients treated with the intensive regimen even though the overall survival did not show a statistically significant difference (63% vs. 50%, P = 0.27). Multivariate analysis showed that the high-dose chemotherapy program was the only independent variable correlating with a reduction in the event rate.Conclusion: Early autologous stem-cell transplantation might improve the clinical outcome of high-risk patients according to IPI.  相似文献

BACKGROUND: The International Prognostic Factors Project on Advanced Hodgkin's Disease developed a seven-factor prognostic score consisting of serum albumin, hemoglobin, gender, stage, age, leukocytosis and lymphocytopenia for newly diagnosed Hodgkin's disease patients who receive chemotherapy. The purpose of this study was to determine whether this prognostic score would also be useful for Hodgkin's disease patients undergoing autologous hematopoietic stem cell transplantation. PATIENTS AND METHODS: We performed a retrospective review of 379 patients who had autologous transplants for Hodgkin's disease, at the University of Nebraska Medical Center between October 1984 and December 1999. Multivariate analysis was performed to determine whether the prognostic factors identified by the International Prognostic Factors Project adversely influenced event-free survival (EFS) or overall survival (OS). RESULTS: Low serum albumin, anemia, age and lymphocytopenia were associated with poorer EFS and OS. Gender, stage and leukocytosis were not associated with significantly poorer outcomes. Estimated 10-year EFS was 38%, 23% and 7% for patients with 0-1, 2-3 or > or =4 of the adverse prognostic characteristics identified by the International Prognostic Factors Project, respectively. CONCLUSIONS: The prognostic score for advanced disease is also useful for relapsed and refractory Hodgkin's disease patients undergoing high-dose therapy followed by autologous hematopoietic stem cell transplantation.  相似文献
