BackgroundCentral nervous system (CNS) lymphoma is associated with poor outcomes. Autologous stem cell transplantation (ASCT) has been reported to improve outcomes when used as a consolidation strategy in primary CNS lymphoma (PCNSL) and as a salvage strategy in patients with disease relapse limited to the CNS. Herein, we describe our experience of using ASCT in PCNSL and secondary CNS lymphoma (SCNSL).Patients and MethodsWe evaluated clinical outcomes of 18 patients from 2 major academic centers with a median age of 55 (range, 46-72) years. Thirteen patients had PCNSL and 5 patients had SCNSL. Most of the cases were in the first (CR1) or second (CR2) complete remission (CR1 = 7, CR2 = 7) at the time of ASCT. Carmustine with thiotepa (n = 12, 67%) was the most commonly prescribed preparative regimen.ResultsThe median follow-up from ASCT for surviving patients was 12 (range, 0.9-115) months. The 2-year progression-free survival (PFS) and overall survival (OS) were 74% (95% confidence interval [CI], 48%-99%) and 80% (95% CI, 55%-100%), respectively. Two-year non-relapse mortality was 0%. The 2-year cumulative incidence of relapse/progression was 27% (95% CI, 10%-72%). In subgroup analysis of PCNSL patients, 2-year PFS, OS, and relapse were 71% (95% CI, 38%-100%), 71% (95% CI, 38%-100%), and 29% (95% CI, 9%-92%), respectively.ConclusionIn this retrospective study of patients with CNS lymphoma, consolidation with ASCT after high-dose methotrexate-based chemotherapy is safe and effective in reducing disease relapse. 相似文献

IntroductionStandard consolidation for primary diffuse large B cell lymphoma (DLBCL) of the central nervous system (CNS) (PCNSL) is not established. This single center, retrospective observational study aims to define the outcomes of consolidative high dose chemotherapy and autologous stem cell transplantation (HDC/ASCT) in patients with PCNSL and isolated secondary CNS DLBCL (SCNSL) and evaluate the prognostic factors.Patients and MethodsAll consecutive patients performed an HDC/ASCT for PCNSL or isolated SCNSLs between October 2012 and February 2022 were identified. Primary endpoints were progression-free survival (PFS) and overall survival (OS).ResultsAmong 35 patients included, 28 had PCNSL and 7 had isolated SCNSL. Median age was 51 (16-78). Males constituted 48.6%. Median follow-up after HDC/ASCT was 42.0 months. MATRIX (51.4%) and TEAM (80.0%) were the most frequent regimens of induction and conditioning, respectively. OS and PFS 1- and 2-year after HDC/ASCT were 68.0%, 57.0%, 58.0%, 48.0%, respectively. Increasing age, poor performance and comorbidities were associated with lower OS and PFS and higher non-relapse mortality (NRM). Complete response (CR) 1 at HDC/ACST was independently associated with higher OS and PFS [hazard ratio (HR): 4.67 and 6.99, respectively].ConclusionIn patients < 60 years consolidative HDC/ASCT yields promising OS and PFS. Patients ≥ 60 years may less likely benefit from consolidative HDC/ASCT and should be studied further in trials of novel agents, lower doses of consolidative radiotherapy and dose-adjusted conditioning regimens. Not only age, but also comorbidities, clinical performance and response to induction correlate with outcomes. Patients with isolated SCNSL may achieve similar outcomes. 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

There is currently no standard therapy for recurrent or chemotherapy-refractory central nervous system lymphoma (CNSL). Pemetrexed has been reported to have activity in patients with primary CNSL (PCNSL). The use of pemetrexed in secondary CNS lymphoma (SCNSL) has not previously been reported. Here we retrospectively review the outcomes and toxicities of standard and modified doses of pemetrexed as salvage therapy in 18 PCNSL and 12 SCNSL patients. The overall response rate for PCNSL patients was 64.7 %, all of whom achieved a complete response (CR). The median progression-free survival (PFS) was 5.8 months. For the SCNSL patients, RR was 58.3 % with 2 CR (16.7 %); the median PFS was 2.5 months. Grade ≥3 adverse events included leukopenia in 5 patients (16.7 %), neutropenia in 1 patient (3.3 %), and fatigue in 3 patients (10.0 %). 3 patients died while on treatment, 2 due to infections and 1 due to pulmonary embolism. Our results indicate that pemetrexed has activity as salvage therapy in recurrent PCNSL, even with modified dosing, but outcomes trend towards less favorable in SCNSL. 相似文献

BackgroundFollicular lymphoma (FL) is characterized by multiple relapses and progressively shorter response durations with subsequent therapies. Despite the development of numerous treatment strategies to reduce the risk of progression, optimal therapeutic strategies for patients with FL remain undefined. Radioimmunotherapy (RIT) with an anti-CD20 antibody linked to iodine-131 or to yttrium-90 has emerged as well-tolerated treatment after induction. We conducted a systematic literature review and meta-analyses to quantify the benefits of consolidative RIT.MethodsWe searched the CENTRAL and MEDLINE libraries, and conference abstracts for reports on phase II/III clinical trials that assessed RIT consolidation for patients with untreated FL. Extracted data included pretreatment disease status, patient characteristics, treatment regimen, response rates, progression-free survival (PFS), and overall survival (OS). Pooled estimates of complete response (CR), overall response (OR), 2- and 5-year PFS and OS rates were computed by using random effects models.ResultsEight studies (n = 783) were included in the meta-analyses. CR rates after RIT ranged from 69.0% to 96.5%, 2-year PFS ranged from 64.8% to 86.1%, and 5-year PFS ranged from 47.0% to 67.3%. The pooled estimates of the CR rate and OR rate were 82.7% (95% CI, 67.4%-91.7%) and 96.2% (95% CI, 90.4%-98.6%), respectively. The pooled estimates for 5-year PFS and OS were 57.6% (95% CI, 47.8%-66.9%) and 90.1% (95% CI, 83.9%-94.1%), respectively.ConclusionsWe believe that these aggregated data can further the discussion on RIT as a consolidation therapy and inform decisions on future study designs Additional studies are needed to compare the benefits of RIT consolidation to maintenance therapy with rituximab. 相似文献

BackgroundIn patients with presumed primary CNS lymphoma (PCNSL), a systemic manifestation is found only in a small minority. Although bone marrow biopsy (BMB) is recommended for staging, its diagnostic value is unclear.MethodsA retrospective analysis of 392 patients with presumed PCNSL from 3 university hospitals and 33 patients with secondary CNS lymphoma (SCNSL) and initial CNS involvement from a multicenter Germany-wide prospective registry was performed.ResultsA BMB was performed and documented in 320/392 patients with presumed PCNSL; 23 had pathologic results. One harbored the same lymphoma in the brain and bone marrow (BM), 22 showed findings in BM discordant to the histology of brain lymphoma; n = 12 harbored a low-grade lymphoma in the BM, the other showed B-cell proliferation but no proof of lymphoma (n = 5), monoclonal B cells (n = 3), or abnormalities not B-cell-associated (n = 2). In the group of SCNSL with initial CNS manifestation, 32/33 patients underwent BMB; 7 were documented with bone marrow involvement (BMI); 1 had concordant results in the brain and BM with no other systemic manifestation. Six had additional systemic lymphoma manifestations apart from the brain and BM.ConclusionsIn only 2 out of 352 (0.6%) patients with CNS lymphoma (320 presumed PCNSL and 32 SCNSL), BMB had an impact on diagnosis and treatment. While collected in a selected cohort, these findings challenge the value of BMB as part of routine staging in presumed PCNSL. 相似文献

BackgroundThe purpose of this study was to assess prognostic factors and outcome of patients with relapsed/refractory Hodgkin's lymphoma (HL) who received high-dose chemotherapy and autologous stem-cell transplant (ASCT).Patients and methodsData on 195 patients who received ASCT between 1985 and June 2005 were reviewed. Median time from first treatment to ASCT was 2.6 years (0.4–27.3). Demography at ASCT was 61% stage IV, median age 31 years (18–69), median prior treatment (tx) regimens 3 (2–7), median Hasenclever index 3 (0–6); 150 patients had responding disease [54 complete remission (CR), 96 partial remission (PR)], and 45 patients had untested relapse/refractory disease.ResultsPost-ASCT, 61% (119/195) patients attained CR with an overall response (CR + PR) of 85%. Twelve patients had nonrelapse mortality. Of 119 patients attaining CR, 27 relapsed: 3 after attaining CR for >5 years and 1 after attaining CR for >10 years. Median overall survival (OS)/progression-free survival (PFS) from ASCT was 9 years/2.9 years. Five-year OS/PFS was 55% of 44% and 10-year OS/PFS was 49.4% of 37% for whole group. Twenty (10%) patients developed second cancer (seven secondary acute myeloid leukaemia (AML)/myelodysplastic syndrome (MDS)). Probability of developing second cancer at 10 years was 14.7% (95% confidence interval 8.9% to 23.8%) and 24.8% at 19 years.ConclusionThese data provide the longest follow-up reported for patients receiving ASCT for relapsed/refractory HL. In addition to previously described prognostic factors, our data show that Hasenclever index <3 influences outcome favorably and attaining CR at ASCT leads to a better outcome. 相似文献

This study was conducted to evaluate the efficacy and safety of Rituximab, Gemcitabine, Cisplatin, and Dexamethasone (R-GDP) in relapsed or refractory aggressive B-Cell Non-Hodgkin's Lymphoma (NHL). Treatments consisted of rituximab 375?mg/m(2), i.v. on day 1; gemcitabine 1,000?mg/m(2), i.v. on days 1 and 8, dexamethasone 40?mg i.v. on days 1-4, and cisplatin 25?mg/m(2) i.v. on days 1-3, every 21?days. The primary end-points were the overall survival (OS) and progression-free survival (PFS). Secondary endpoints included response rate (ORR; CR) and toxicities. Eligible patients could then proceed to high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) or receive up to six treatment cycles. From January 2005 to December 2010, 50 successive patients at Tianjin cancer hospital lymphoma department were enrolled in this study. All patients were recurrent or refractory aggressive B-cell NHL, including diffuse large B-cell lymphoma (n?=?30) and follicular lymphoma grade 3b (n?=?20). The median follow-up time was 42?months (range, 12-70). After two cycles, the overall response rate was 72.0?%, with a CR/CRu rate of 56?%. The 2-year OS and PFS of all patients were 70.0 and 48.0?%, respectively. Grade III-IV neutropenia and thrombocytopenia occurred in 34 and 40?% of patients, respectively. Twenty-one patients (42?%) proceeded to ASCT. Higher International Prognostic Index and refractory disease were independently associated with worse survival and progression-free survival. R-GDP chemotherapy in patients with refractory or relapsed aggressive B-Cell NHL was effective as a salvage therapy and helpful for HDC/ASCT. 相似文献

背景与目的:原发性中枢神经系统淋巴瘤(primary central nervous system lymphoma,PCNSL)是发生在脑、脊髓、脑膜或眼的罕见侵袭型非霍奇金淋巴瘤,无CNS之外的部位累及。PCNSL与其他类型淋巴瘤相比,患者生存期短,预后差,且复发率高,未经治疗的患者的中位生存期仅为3个月。近年来研究发现C-MYC、BCL-2、BCL-6、Ki-67等指标在一定程度上影响PCNSL患者预后。因此,通过分析PCNSL相关蛋白表达、治疗方式及其他临床因素对患者预后的影响, 希望为该病的临床治疗及预后评价进一步积累资料。方法:回顾性分析自2013年6月—2021年5月于大连医科大学附属第二医院治疗的42例经病理学检查明确诊断为原发性中枢神经系统弥漫大B细胞淋巴瘤患者的临床资料,包括性别、年龄、病灶数量、美国东部肿瘤协作组(Eastern Cooperative Oncology Group,ECOG)评分、血清乳酸脱氢酶(lactate dehydrogenase,LDH)、病灶是否累及深部脑组织、治疗方案、病理学Hans分型及C-MYC、BCL-2、BCL-6、Ki-67等生物标志物,结合随访调查,了解患者生存时间及生存状况,应用Kaplan-Meier法及log-rank检验分析影响患者无进展生存期(progression-free survival,PFS)和总生存期(overall survival,OS)的预后相关因素,多因素分析采用COX回归模型。结果:42例PCNSL患者中位发病年龄61岁,男女比例为1.33∶1.00,颅脑增强MRI病灶多呈均匀明显强化。所有患者均接受含有大剂量甲氨蝶呤(high-dose methotrexate,HD-MTX)方案化疗,治疗后评价完全缓解(complete response,CR)20例、部分缓解(partial response,PR)5例,疾病稳定(stable disease,SD)11例,疾病进展(progressive disease,PD)6例。中位PFS为21个月,中位OS为34个月,1年PFS率为63.7%,2年PFS率为47.0%;1年OS率为70.8%,2年OS率为55.6%。单因素分析结果显示,影响PFS的因素是HD-MTX多药联合化疗、鞘内化疗及联合利妥昔单抗。影响OS的因素是ECOG评分≥2、C-MYC(+)、BCL-2及C-MYC双表达、HD-MTX多药联合化疗、鞘内化疗及联合利妥昔单抗。多因素分析结果显示:利妥昔单抗治疗是影响PFS的独立预后因素(P=0.020),ECOG评分、利妥昔单抗是影响OS的独立预后因素(P=0.007;P=0.046)。与未接受巩固治疗的患者相比,接受巩固治疗患者的中位PFS及OS较高;进一步的亚组分析显示,自体干细胞移植(autologous stem cell transplantation,ASCT)组的中位PFS及OS较全脑放疗(whole brain radiation therapy,WBRT)组高,但差异无统计学意义。结论:PCNSL多发于中老年人,男性多于女性,影像学缺乏特异性。ECOG评分≥2与PCNSL患者较差的OS相关。C-MYC(+)、BCL-2及C-MYC双表达可作为指导危险分层的预后标志物。以HD-MTX为基础的多药联合化疗已经成为PCNSL的首选治疗手段,利妥昔单抗的应用可延长生存期。在全身化疗的基础上,联合局部鞘内化疗可以改善预后。进一步的巩固治疗主要包括ASCT及WBRT,可延长PFS及OS,ASCT可以取得与WBRT相似的疗效,且可避免WBRT的晚期神经毒性,但本研究中因样本量及随访时间的限制,未得出明确的统计学结果。 相似文献

BackgroundThe best consolidation strategy after induction chemotherapy in Primary CNS Lymphoma (PCNSL) remains controversial. Our objective is to estimate the overall survival (OS) for autologous stem cell transplantation (ASCT) versus whole brain radiation (WBRT) in the consolidation setting. We also sought to evaluate the factors affecting treatment selectionMethodsWe identified 1620 patients with PCNSL who received chemotherapy followed by either ASCT or WBRT between 2004 and 2015 from the National Cancer Database. A propensity score weighting methodology was used to compare survival outcomes. Factors affecting treatment selection were investigated using a logistic regression model. Annual percentage change (APC) was calculated to assess the trend of ASCT use.ResultsOnly 12.2% of patients received ASCT, and this proportion rose steadily between 2004 and 2015, with APC of +23%. Treatment selection was affected by age, type of area, distance from the treating facility, and level of education. With a median follow-up of 68.4 months, adjusted-median OS was 91.4 months and not reached for WBRT and ASCT groups, respectively (P < .001). 5-year OS was 74.4% in the ASCT group versus 58.7% in the WBRT group (HR 0.40, 95% CI 0.27-0.60, P -value < .01).ConclusionSocioeconomic factors affect the selection of consolidative treatment in patients with PCNSL which can alter outcomes. Frequency of consolidative ASCT is increasing for patients with PCNSL. This is the first and largest cohort study, to our knowledge, to show an OS advantage in favor of ASCT. This OS benefit needs to be confirmed in a randomized controlled fashion. 相似文献

High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a therapeutic option for patients with relapsed follicular lymphoma (FL). The clinical characteristics and outcomes of FL relapse after ASCT in the rituximab era have not yet been fully elucidated. We retrospectively reviewed 414 FL patients treated with ASCT between 2000 and 2014 in four hematology departments. All patients received rituximab as a first-line treatment. We specifically analyzed the clinical characteristics, treatment strategies at relapse, and outcomes of 95 patients (23%) who relapsed after ASCT. The patients (median age, 57 y) received a median of two lines of therapy (range, 2-6) prior to ASCT, with 92% in complete response (CR) or partial response (PR) before ASCT. Histological transformation at relapse after ASCT was observed in 20% of the patients. Treatment at relapse after ASCT consisted of chemotherapy with or without rituximab (n = 45/90, 50%), targeted agents (18%), rituximab monotherapy (14%), or consolidation allogeneic transplantation after induction chemotherapy (12%) and radiotherapy (6%). After relapse, the median progression-free survival (PFS) and overall survival (OS) were 1 year (95% CI, 0.541-1.579) and 5.5 years (95% CI, 1.910-9.099), respectively. In the multivariate analysis, histological transformation (HT) was associated with OS (P = .044; HR 2.439; 95% CI, 1.025-5.806), and a high FLIPI score at relapse was associated with PFS (P = .028; HR 2.469; 95% CI, 1.104-5.521). This retrospective study showed that the period of PFS of patients who relapsed after ASCT is short. A biopsy should be performed for these patients to document the HT. Our results indicate that new treatment strategies will need to be developed for these patients. 相似文献

BackgroundHigh-dose chemotherapy followed by autologous stem-cell transplantation (HCT–ASCT) is a promising approach in eligible patients with primary central nervous system lymphoma (PCNSL). We report long-term data of patients who were treated according to HCT–ASCT containing protocols.Patients and methodsWe analyzed survival and relapse rates in 43 (<67 years) immunocompetent patients with newly diagnosed PCNSL being treated according to two different high-dose methotrexate-based protocols followed by high-dose carmustine/thiotepa (BCNU/TT) plus ASCT (±whole brain irradiation). Analysis was conducted for all patients (intention-to-treat) and those patients who actually received HCT–ASCT (per-protocol).ResultsThirty-four patients achieved complete remission, of those 12 relapsed (35%), while 6 of them relapsed 5 years after diagnosis. After a median follow-up of 120 months, median overall survival (OS) was reached after 104 months. Two- and 5-year OS was 81% and 70% and 2- and 5-year event-free survival (EFS) was 81% and 67%, respectively. In per-protocol analysis (N = 34), 5-year OS and EFS was 82% and 79%, respectively. HCT–ASCT associated related mortality was not observed.ConclusionsSequential high-dose MTX containing chemotherapy followed by high-dose carmustine/thiotepa plus ASCT (±whole brain irradiation) is safe and leads to high survival rates in eligible patients with newly diagnosed PCNSL. 相似文献

BACKGROUND: The reported probability of survival of patients with Hodgkin's disease (HD) following high-dose chemotherapy with autologous stem cell transplantation (HDC/ASCT) is 35-65% at 5 years. The Polish Lymphoma Research Group investigated retrospectively prognostic factors for overall survival (OS) and event-free survival (EFS), and the risk of secondary malignancies in a large series of patients who underwent HDC/ASCT. PATIENTS AND METHODS: The data of 341 consecutive patients treated in 10 centers from 1990 to 2002 were collected and analyzed. RESULTS: The actuarial 5-year OS and EFS were 64% [95% confidence interval (CI) 57% to 71%] and 45% (95% CI 39% to 51%), respectively. In the multivariate model, unfavorable prognostic factors for EFS were less than partial response at the time of ASCT [relative risk (RR), 2.92 (95% CI 1.68-5.08); P<0.001] and three or more previous chemotherapy lines (RR, 2.16; 95% CI 1.42-3.30; P<0.001). These two factors were also associated with unfavorable OS (RR, 3.32; 95% CI 1.90-5.79; P<0.001 and RR, 2.34, 95% CI 1.51-3.64; P<0.001). Five-year cumulative risk of secondary malignancy was 8.4% (95% CI 2% to 13%) and the only identified risk factor was splenectomy (P=0.02). CONCLUSIONS: HDC/ASCT should be considered early in the course of disease for patients with a response after standard therapy. 相似文献

Purpose: We developed and evaluated a regimen including fotemustine, teniposide and dexamethasone (FTD)for treating patients with central nervous system (CNS) lymphoma based on pharmacokinetic properties ofindividual agents and in combination. Patients and Methods: In a comparison study, 8 patients with primaryCNS lymphoma (PCNSL) and 8 with secondary CNS lymphoma (SCNSL) were treated with FTD (comprisingfotemustine 100 mg/m2, 1h infusion, day 1; teniposide 60 mg/m2, >0.5 h infusion, on day 2, 3, 4; dexamethasone 40mg, 1h infusion, on day 1, 2, 3, 4 and 5; and methotrexate 12 mg, cytosine arabinoside 50 mg plus dexamethasone5 mg intrathecally, on day 2 and 7). Cycles were repeated every 3 weeks. After response assessment, patientsreceived whole brain radiotherapy. Results: Of the 8 PCNSL patients, 4 (50%) achieved CR and 3 (38%) PR, anoverall response rate of 88%. Four patients (50%) were in continuing remission at the end of this study after amedian follow-up of 30 months (range 10 to 56 months). Of the 8 SCNSL patients the overall response rate was63% (CR+PR: 38%+25%). All responses were achievable with predictable toxicity mainly reflecting reversiblemyelosuppression. Conclusion: This study suggests that FTD could be an effective treatment for CNS lymphoma,and is worthy of further evaluation. 相似文献

IntroductionSynchronous involvement of the central nervous system (CNS) at the diagnosis of systemic non-Hodgkin lymphoma (NHL) is associated with an increased risk for relapse despite complete remission to initial therapy. High-dose chemotherapy with a CNS-directed conditioning regimen followed by autologous stem cell transplantation (ASCT) holds promise as a consolidative approach.Patients and MethodsWe conducted a retrospective analysis of all patients with systemic B-cell NHL and synchronous CNS involvement who received upfront consolidation with high-dose chemotherapy with thiotepa, busulfan, cyclophosphamide, and ASCT while in first complete remission between July 2008 and June 2016 at 2 partner academic institutions.ResultsTwenty patients were identified through the transplant database. The median age at diagnosis was 53 years (range, 37-65 years). The majority had diffuse large B-cell lymphoma histology (n = 17; 85%). The sites of CNS involvement were parenchymal (n = 12; 60%) and leptomeningeal disease (n = 9; 45%). All patients received systemic and CNS-directed therapy prior to transplant, with the most common approaches being R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisolone) (n = 13; 65%) and high-dose intravenous methotrexate (n = 16; 80%), respectively. With a median follow up of 4.4 years after ASCT (range, 2 months-8.5 years), the Kaplan-Meier estimates of 4-year progression-free and overall survival were 77% (95% confidence interval, 48%-91%) and 82% (95% confidence interval, 54%-94%), respectively.ConclusionCNS-directed high-dose chemotherapy and ASCT provides durable remission for patients with synchronous aggressive lymphoma and should be strongly considered as consolidative therapy for eligible patients with systemic NHL with CNS involvement in first complete remission. 相似文献

The present study aimed to analyse the treatment outcome of IMVP-16/Pd (ifosfamide, methotrexate, etoposide and prednisone) followed by high-dose chemotherapy and autologous stem cell transplantation (HDC/ASCT) for patients with peripheral T-cell lymphomas (PTCLs) who were previously treated with CHOP. Since 1995, 32 PTCL patients were treated with IMPV-16/Pd. Nine of 32 patients achieved a response (5 demonstrating complete response (CR) and 4 partial response), with an overall response rate of 28.1% (95% onfidence interval 0.12-0.45). Considering histopathologic subtypes, 3 of 4 relapsed natural killer (NK)/T-cell lymphoma patients (75%) achieved CR, but only 1 of 6 in non-NK/T-cell lymphoma patients (16.7%) achieved CR (P = 0.19). Six of 9 IMVP-16/Pd sensitive patients underwent HDC/ASCT. Three of them relapsed after 3, 4 and 15 months, respectively, of HDC/ASCT. Estimated 3-year overall survival and progression-free survival rates were 14.2% and 12.2%, respectively. Multivariate analysis revealed that responsiveness to first-line CHOP was a significant prognostic factor (P < 0.05). These results indicate that IMVP-16/Pd followed by HDC/ASCT appears to be an effective salvage regimen, especially for NK/T-cell lymphoma. 相似文献

BackgroundTumor regression after antiviral therapy (AT) is in favor of an etiological role of hepatitis C virus (HCV) in non-Hodgkin's B-cell lymphomas (NHL).Patients and methodsWe carried out a cohort study of 704 consecutive HIV-negative, HCV-positive patients with indolent NHL diagnosed and treated from 1993 to 2009 in 39 centers of the Fondazione Italiana Linfomi; 134 patients were managed with AT for lymphoma control.ResultsFor entire cohort, 5-year overall survival (OS) was 78% [95% confidence interval (CI): 74%–82%] and 5-year progression-free survival (PFS) was 48% (95% CI: 44%–53%). In multivariate analysis, the use of AT during the patients’ life had positive impact on OS. Forty-four of the 100 patients treated with first-line AT achieved a complete remission (CR) and 33 a partial response (PR). HCV-RNA clearance was achieved in 80 patients and was related to lymphoma response. At a median follow-up of 3.6 years, 5-year PFS was 63% (95% CI: 50%–73%). CR + PR rate was 85% with AT as second-line treatment.ConclusionAT produces HCV-RNA clearance and consequent tumor regression in most patients with HCV-related indolent NHL. AT used at any time is associated with improved OS. Consequently, AT can be considered an option for patients with indolent lymphomas who do not need immediate cytoreductive treatment. 相似文献

IntroductionOptimal management of elderly patients with primary central nervous system lymphoma (PCNSL) after induction therapy is unclear. Whole-brain radiotherapy and autologous stem cell transplantation carry increased toxicity in patients older than 60 years of age, which might outweigh the benefits in this group. Temozolomide (TMZ) has established antineoplastic activity in the central nervous system in other disease states, with a favorable toxicity profile.Patients and MethodsWe report efficacy and tolerability in a series of 10 patients treated off-label with TMZ maintenance after completion of R-MPV (rituximab, methotrexate, procarbazine and vincristine) treatment for or primary diagnosed PCNSL.ResultsMedian progression-free survival (PFS) was 57 months, 2-year PFS was 67%, and 5-year PFS was 33%. Median overall survival (OS) was 63 months, 2-year OS was 88%, and 5-year OS was 57%. TMZ was generally well tolerated, with the most common toxicity of Grade 3 or higher being thrombocytopenia in 3 patients (30%).ConclusionThese outcomes suggest that TMZ might have activity for maintenance in elderly patients with PCNSL, when more aggressive treatments are contraindicated. 相似文献

Although induction immunochemotherapy including high‐dose cytarabine and rituximab followed by high‐dose chemotherapy (HDC) with autologous stem cell transplantation (ASCT) is recommended for younger patients (≤65 years old) with untreated mantle cell lymphoma (MCL), no standard induction and HDC regimen has been established. We conducted a phase II study of induction immunochemotherapy of R‐High‐CHOP/CHASER followed by HDC of LEED with ASCT in younger patients with untreated advanced MCL. Eligibility criteria included untreated MCL, stage II bulky to IV, and age 20‐65 years. Patients received 1 cycle of R‐High‐CHOP followed by 3 cycles of CHASER every 3 weeks. Peripheral blood stem cells (PBSC) were harvested during CHASER. LEED with ASCT was delivered to patients who responded to R‐High‐CHOP/CHASER. Primary endpoint was 2‐year progression‐free survival (PFS). From June 2008 to June 2012, 45 patients (median age 59 years; range 38‐65 years) were enrolled. PBSC were successfully harvested from 36 of 43 patients. Thirty‐five patients completed ASCT. Two‐year PFS was 77% (80% CI 68‐84), which met the primary endpoint. Five‐year PFS and overall survival were 52% (95% CI 34‐68%) and 71% (95% CI 51‐84%), respectively. Overall response and complete response rates after induction immunochemotherapy were 96% and 82%, respectively. The most common grade 4 toxicities were hematological. In younger patients with untreated MCL, R‐High‐CHOP/CHASER/LEED with ASCT showed high efficacy and acceptable toxicity, and it can now be considered a standard treatment option. 相似文献
