Elderly aggressive-histology non-Hodgkin's lymphoma: first-line VNCOP-B regimen experience on 350 patients.

Age is a risk factor and a prognostic parameter in elderly aggressive-histology non-Hodgkin's lymphoma (NHL) patients. Several adapted chemotherapeutic regimens have recently been designed and tested on elderly patients. Several of these trials have shown that older aggressive-histology NHL patients can benefit from specific and adequate treatment capable of curing a percentage of these patients. Between January 1992 and September 1997, 350 previously untreated aggressive-histology NHL patients greater than 60 years of age were treated with a combination therapy including cyclophosphamide, mitoxantrone, vincristine, etoposide, bleomycin, and prednisone (VNCOP-B). Complete remission (CR) was achieved by 202 (58%) patients and partial remission (PR) by 87 (25%), whereas the remaining 61 (17%) patients were nonresponders. The overall response rate (CR + PR) was 83%. Clinical and hematologic toxicities were modest, because 71% of the patients received granulocyte colony-stimulating factor (G-CSF). The CR rates for the three age groups (60 to 69, 70 to 79, and >/=80 years) were similar: 61%, 59%, and 56%, respectively. At 5 years, the relapse-free survival rate was 65%, the overall survival rate was 49%, and the failure-free survival rate was 33%. In the multivariate analysis, prognostic factors associated with longer survival or longer relapse-free survival turned out to be localized disease stage (P =.001) and good performance status (P =.0002). Application of the International Prognostic Factor Index was significantly associated with outcome (P =.001). These data confirm on a large cohort of patients that the VNCOP-B regimen is effective in inducing good CR and relapse-free survival rates with only moderate toxic effects in elderly aggressive-histology NHL.     

Malignant lymphomas in the elderly: a single institute experience highlights future directions

In this study, our experience with the diagnostics and treatment of malignant lymphoma patients were analyzed, with a special consideration of the elderly. Between 1980 and 2005, there were 181 cases found (35%) among 517 non-Hodgkin's lymphoma (NHL) patients and 46 cases (8.1%) among 565 Hodgkin's lymphoma (HL) patients, who were at least 65 years old at the time of diagnosis. Comparing elderly patients to young ones, the time from first symptoms to diagnosis was significantly longer (NHL: 7.6 months versus 4.1 months, HL: 11.4 months versus 5.6 months). B-cell and indolent NHL-s were more common (92.8% versus 79.2% and 56.4% versus 35.1%) such as classical lymphocyte predominant (cLP) HL-s (30.4% versus 15.0%); however nodular sclerosis (NS) HL-s occurred less frequently (10.9% versus 32.2%). Stages were more advanced and comorbidity was more common. Primary therapies were more often inappropriate (NHL: 20.4% versus 5.1%, HL: 26.0% versus 6.0%); there were more complications, but less cases with complete remission (NHL: 17.1% versus 61.1%, HL: 63.0% versus 79.2%) and dose reductions were more commonly applied (NHL: 46.7% versus 17.2%, HL: 52.9% versus 11.3%). Remission rates were significantly worsened by dose reductions (NHL: 68.5% versus 34.5%, HL: 61.8% versus 44.4%). Appropriate therapies resulted in significantly better overall survival (OS) rates (log-rank<0.05). It can be concluded that more favourable results can be achieved in the remission and survival rates of elderly malignant lymphoma patients if the appropriate curative or palliative therapies, considering new and less toxic protocols such as supportive care, are chosen.     

Philadelphia chromosome-positive acute lymphoblastic leukemia in the elderly: prognostic factors and treatment outcome

Data on all patients diagnosed with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) aged 55 or older, seen in our institution over a 17-year period, were studied to determine the incidence and range of clinical and biological subtypes, and the outcome of different therapeutic approaches. Twenty-five Ph+ ALL cases (median age: 64 years) were diagnosed between 1986 and 2003 (28% of all B-lineage elderly ALL seen during this period). Karyotypic analysis was performed successfully in 22 cases, while 3 were only diagnosed by molecular biology analysis. All patients had B-cell lineage ALL. Co-expression of myeloid markers was observed in 20% of tested cases. One patient died before chemotherapy could be given. All other patients received "curative" treatment according to different protocols used during the period of study. Overall the complete remission (CR) rate was 76% (95% confidence interval, CI: 55-91%). Fifteen patients achieved CR after one course of chemotherapy and 4 patients after salvage therapy. Median disease-free survival (DFS) of the entire cohort was 5.6 months (95% CI: 4.5-8.4 months) and median overall survival was 10.1 months (95% CI: 7.9-13 months). In multivariate analysis, age>or=70 years was of poor prognostic value for achieving CR (p=0.05) and hyperleukocytosis at diagnosis was of poor prognostic value for overall survival (p=0.001). Overall survival duration was not significantly influenced by achieving CR. Ph+ ALL patients did not show a significant difference in terms of outcome as compared with Philadelphia-negative ALL patients. The very poor overall outcome in elderly patients with Ph+ ALL may be significantly improved by the introduction of imatinib mesylate into current treatment regimens.     

Autologous stem cell transplantation for anaplastic large-cell lymphomas: results of a prospective trial

Autologous stem cell transplantation (ASCT) in the front line treatment of non-Hodgkin's lymphoma (NHL) remains controversial. Anaplastic large-cell lymphoma (ALCL) is known to have its own clinical and biological features. The outcome of ALCL patients treated with high-dose chemotherapy and ASCT as part of their first-line therapy was analysed in 202 intermediate or high-grade NHL patients in a prospective randomized trial. First-line chemotherapy comprised two alternating anthracycline-containing regimens. Responding patients were autografted after a BEAM (BCNU, cytarabine, etoposide and melphalan) regimen. Patients with bulky or residual masses were irradiated. Fifteen patients with ALCL were identified by morphological and immunological features (CD30 was expressed in 14 out of 15 patients, three patients expressed B-cell markers, five patients expressed T-cell markers and seven patients did not express cell markers). Anaplastic lymphoma kinase (ALK) expression was confirmed in seven cases. The median age was 39 years with a predominant male sex ratio (2.75). Thirteen patients were stage >/= III and six presented with two or more adverse prognostic factors. According to the international age-adjusted prognostic index, the expected complete remission (CR), event-free survival (EFS) and overall survival (OS) rates were 69%, 71% and 69%. Two deaths were observed (one due to interstitial pneumonitis, one due to pulmonary carcinoma). All patients entered CR, no relapse occurred and EFS and survival reached 87% with a follow-up of more than 5 years. These results differ significantly from those observed in the other 176 lymphoma patients: event-free survival was only 53 +/- 5% and OS reached 60 +/- 4% with a median follow-up of 56 months (P = 0.006). Intensified chemotherapy with autologous stem cell support appeared effective in the treatment of ALCL, offering patients the real chance of a cure.     

Retrospective study of prognostic factors in non-Hodgkin lymphoma secondarily involving the central nervous system

The aim of this retrospective single-center study was to analyze the clinical characteristics and outcome of non-Hodgkin lymphoma (NHL) patients with central nervous system (CNS) involvement and to identify prognostic factors for survival. We searched our hospital records for NHL patients diagnosed with CNS involvement from 1982 to 2004, and 43 patients were identified. The median age was 63 years (range 23–88) and the median Karnofsky performance status was 55% (range 10–90). Treatment of CNS lymphoma included intrathecal chemotherapy in 33 patients (77%), systemic chemotherapy in 25 (58%), and radiotherapy in 16 (37%). Twenty-six patients showed a CNS response. The median survival after CNS manifestation was 5 months (range 2 days–82.5+months). Nine patients achieved long-term survival. Low lactate dehydrogenase (LDH) at CNS manifestation and a CNS response to therapy were favorable independent prognostic factors for survival in multivariate analysis (p=0.051 and p<0.0005, respectively), whereas a young age at initial diagnosis, initial CNS involvement, an initially normal LDH, and high-dose chemotherapy for CNS involvement were significant in univariate analysis. In conclusion, long-term survival can be achieved in patients with secondary CNS lymphoma. LDH at CNS manifestation and a CNS response to therapy were significantly associated with survival.     

Guideline for the laboratory diagnosis of functional iron deficiency

Patients with aggressive non‐Hodgkin lymphoma (NHL) who relapse after autologous stem cell transplantation (ASCT) have a poor prognosis. Additional therapy is often poorly tolerated, and new treatment modalities are needed. This efficacy and safety study was a retrospective analysis of two phase II trials (NHL‐002 and NHL‐003) that studied single‐agent lenalidomide in patients with relapsed/refractory aggressive NHL with prior (n = 87) compared with no prior ASCT (n = 179). The overall response rate in the ASCT group was 39% [14% complete response (CR)], including 29% in patients with diffuse large B‐cell lymphoma, 63% in mantle cell lymphoma, and 60% in transformed lymphoma. The timing of transplant relative to receiving lenalidomide had no effect on outcomes. Median progression‐free survival for the ASCT group was 3·7 months (16·9 months for patients in CR; 7·3 months for partial responders) at a median 12·5‐month follow‐up. Median response duration was 7·9 months. Regardless of prior ASCT, lenalidomide monotherapy was efficacious in heavily pretreated patients with aggressive, relapsed/refractory NHL, with a safety profile that was consistent with prior studies of single‐agent lenalidomide.     

VB-CHEP chemotherapy regimen for aggressive non-Hodgkin's lymphomas

Abstract: Despite intensive search for the optimal combination chemotherapy for aggressive non-Hodgkin's lymphoma (NHL), the CHOP (cyclophosphamide, adriamycin, vincristine and prednisolone) regimen is still the standard therapy. We investigated the clinical efficacy of a new combination regimen consisting of vincristine, bleomycin–cyclophosphamide, adriamycin, etoposide and prednisolone (VB-CHEP) in patients with aggressive NHL. A total of 29 patients with aggressive NHL was enrolled into the protocol. Eight patients were consolidated with cisplatin and cytarabine and 5 patients received radiotherapy for bulky disease. Objective response was achieved in 82.8% of the patients. Complete remission (CR) and partial remission rates were 72.4%, and 10.3%, respectively. CR rate was significantly lower in patients with advanced stage, extranodal disease and bone marrow involvement. Median follow-up time is 34+ months; 17 patients are disease-free while 12 died and only 2 patients with CR have relapsed so far. Median response duration is 29+ months and the median survival is 48+ months. The survival rate is 69% in the first year and 66% in the second year. A total of 152 cycles were evaluated for toxicity. Major hematological toxicity was myelosuppression and neutropenia, detected in 50.65%, was mostly grades 1–2. Neutropenic fever occurred in only 11 cycles. The side effects of the consolidation therapy were also acceptable. We conclude that the VB-CHEP regimen with consolidation therapy for high-risk patients may be an effective treatment for advanced stage aggressive NHL.     

Philadelphia Chromosome-positive Acute Lymphoblastic Leukemia in the Elderly: Prognostic Factors and Treatment Outcome

Data on all patients diagnosed with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) aged 55 or older, seen in our institution over a 17-year period, were studied to determine the incidence and range of clinical and biological subtypes, and the outcome of different therapeutic approaches. Twenty-five Ph+ ALL cases (median age: 64 years) were diagnosed between 1986 and 2003 (28% of all B-lineage elderly ALL seen during this period). Karyotypic analysis was performed successfully in 22 cases, while 3 were only diagnosed by molecular biology analysis. All patients had B-cell lineage ALL. Co-expression of myeloid markers was observed in 20% of tested cases. One patient died before chemotherapy could be given. All other patients received "curative" treatment according to different protocols used during the period of study. Overall the complete remission (CR) rate was 76% (95% confidence interval, CI: 55-91%). Fifteen patients achieved CR after one course of chemotherapy and 4 patients after salvage therapy. Median disease-free survival (DFS) of the entire cohort was 5.6 months (95% CI: 4.5-8.4 months) and median overall survival was 10.1 months (95% CI: 7.9-13 months). In multivariate analysis, age≥70 years was of poor prognostic value for achieving CR ( p =0.05) and hyperleukocytosis at diagnosis was of poor prognostic value for overall survival ( p =0.001). Overall survival duration was not significantly influenced by achieving CR. Ph+ ALL patients did not show a significant difference in terms of outcome as compared with Philadelphia-negative ALL patients. The very poor overall outcome in elderly patients with Ph+ ALL may be significantly improved by the introduction of imatinib mesylate into current treatment regimens.     

Long-term Results of a Multicenter Randomized, Comparative Trial of Modified CHOP versus THP-COP versus THP-COPE Regimens in Elderly Patients with Non-Hodgkin’s Lymphoma

In treating elderly non-Hodgkin's lymphoma (NHL) patients, it is particularly important to use drugs that have a low incidence of adverse events and high efficacy. In this multicenter study, THP (pirarubicin)-COP (cyclophosphamide, vincristine, and prednisolone) was compared to two thirds dosage of full CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) regimen with regard to both adverse events and efficacy. For a third group, etoposide (E) was added to the THP-COP regimen (THP-COPE) in order to achieve high dose-intensity. Subjects were 486 previously untreated patients, aged 65 or older (range, 65-92 years; median, 74 years), with NHL. Subjects were randomly assigned to receive THP-COP, two thirds CHOP, or THP-COPE. Four hundred and forty-three patients were assessed for response and followed for 8 years after the last subject registered. The complete remission rates for the THP-COP, CHOP, and THP-COPE groups were 42.5%, 41.4%, and 48.0%, respectively. There was no difference in overall survival or progression-free survival among these 3 groups. In aggressive lymphoma, there was also no difference in complete response (CR) rate (45.3% in THP-COP, 44.9% in CHOP, 48.0% in THP-COPE), overall survival, and progression-free survival among these groups.The 5- and 8-year survival rates for all patients were 29.4% and 18.7%, respectively.The 5- and 8-year survival rates for patients with aggressive lymphoma were 27.4% and 17.4%, respectively. Although long-term survival for patients with aggressive lymphoma on our regimens was not worse compared to previous reports, the CR rate was lower. Because severe adverse events were not observed, higher dose chemotherapy may be directed to achieve better CR rates. In patients with T-cell-type lymphoma, the CR rate was greater after treatment with THP-COP (51.4%) or THP-COPE (57.7%) compared to treatment with CHOP (19.4%). Pirarubicin may be more useful for T-cell lymphoma than doxorubicin. Because adverse cardiac events were reported only in CHOP, adverse cardiac events might be low in the THP group.     

Intensive cytotoxic therapy followed by autologous bone marrow transplantation for non-Hodgkin's lymphoma of high-grade malignancy

Fourteen patients with non-Hodgkin's lymphoma (NHL) of high-grade malignancy were treated with cyclophosphamide and total body irradiation followed by autologous bone marrow transplantation (ABMT). All patients were pretreated with conventional chemotherapy. Three of four patients with drug-resistant disease achieved complete remission (CR), but relapse occurred within six months. Four patients in partial remission (PR) achieved CR; one died because of sepsis, two relapsed within six months, and one is still in CR 28+ months later. Six were treated in CR, five in first CR, and one in second CR. From these six patients (who received this treatment as consolidation therapy), five are in unmaintained CR seven to 31+ months after ABMT (one patient died of a secondary illness). There were two therapy-related deaths, both in patients with a poor clinical condition. Toxicity of this treatment was mild for those receiving transplants who were in better condition. These preliminary results suggest that intensive cytoreductive therapy followed by ABMT may improve disease-free survival in patients in NHL of high-grade malignancy in CR.     

Treatment of elderly patients with intermediate- and high-grade non-Hodgkin's lymphoma: a retrospective population-based study

PURPOSE AND METHODS: Nowadays more people are becoming older. The median age of a patient with non-Hodgkin's lymphoma (NHL) at diagnosis is over 60 years. The incidence of NHL in elderly has increased in the last decades. Therefore, in the future, NHL will be diagnosed more often in the elderly. Data of all patients in the south-east of the Netherlands with newly diagnosed NHL between January 1991 and January 1995 were analysed in a retrospective multicentre population-based study to investigate if and how elderly patients (> 60 years) with advanced NHL (Ann Arbor Staging > or = IIB) of intermediate- and high-grade malignancy were treated. Treatment modalities applied, outcome, and causes of death were evaluated. Treatment was considered inadequate if it deviated from the standard anthracycline-containing chemotherapy (CNOP/CHOP) for a minimum of six cycles. RESULTS: The entry criteria were met by 68 patients. Of these patients, 57 (83.8%) were treated and 11 (16.2%) were not treated. The treatment consisted of CHOP (36 patients), CNOP (6 patients), chlorambucil (13 patients), or COP (2 patients). Forty-two of 68 patients had adequate treatment, but 14 of 42 (33.3%) patients had a suboptimal numbers of cycles (< 6). Of 28 patients with adequate chemotherapy, only 16 had the optimal number of cycles and dose; the result is that the treatment of 76.5% (52/68) of patients differed from that of their younger counterparts. The most important reason for treatment not being optimal was high age (23%) or poor performance (35%). In the appropriately treated patients, 62.5% (10/16) had a complete response. Survival in the CHOP/CNOP-treated group was better than in other groups. The main cause of death in the total study group was NHL. The results cannot be explained by the different international prognostic index. CONCLUSION: A significant subset (76.5%) of elderly people with intermediate/high-grade NHL received suboptimal therapy, mainly because of a suboptimal performance status. However, a significant part of the patients (23%) were not treated optimally because of high age, despite a good performance. For improving the overall survival in the elderly, it is not only the schedule that is important, but also the intention to treat the elderly patient.     

Allogeneic bone marrow transplantation in aggressive non-Hodgkin's lymphoma (excluding Burkitt and lymphoblastic lymphoma): a series of 73 patients from the SFGM database

The place of allogeneic bone marrow transplantation (BMT) in the treatment of aggressive non-Hodgkin's lymphoma (NHL) remains controversial. We conducted a retrospective study of French experience in allografting NHL between 1984 and 1994. To improve the homogeneity of the study population, cases of low-grade, Burkitt and lymphoblastic NHL were excluded. 73 patients were included in the analysis. Median age at transplantation was 35 years (range 9-61 years); 64 patients were in stage IV and 45 had bone marrow involvement at diagnosis. At the time of transplantation, 46 patients had sensitive disease (25 in complete remission; CR). The overall survival (OS) and progression-free survival (PFS) rates were 41% and 40% respectively at 5 years (median follow-up of survivors 90 months). The probability of disease progression was 30% at 5 years, and only one relapse occurred after 15 months. 32 patients died of transplantation-related complications. In multivariate analysis, pretransplant complete remission was the main factor associated with longer survival (OS at 60 months of 76% among the 25 patients in CR at transplant and of 23% among the 48 patients not in CR at transplant). Neither acute nor chronic graft-versus-host disease (GvHD) influenced the relapse rate. In conclusion, in this high-risk population the overall results of allogeneic BMT were encouraging, despite a high transplant-related mortality rate. We believe this procedure should be studied further in prospective controlled trials.     

The Role of Intensive Therapy and Autologous Blood and Marrow Transplantation for Chemotherapy-Sensitive Relapsed and Primary Refractory Non-Hodgkin’s Lymphoma: Identification of Major Prognostic Groups

Patients with intermediate grade non-Hodgkin's lymphoma (NHL) who relapse or fail to achieve a complete remission after anthracycline-containing induction regimens have a poor outcome with conventional-dose salvage treatment. This outcome may be improved with intensive therapy and autologous transplantation (ABMT) but even in patients with proven chemotherapy-sensitive disease, relapse rates of up to 60% are observed. Reliable and powerful prognostic indicators are needed to identify appropriate patients for this expensive procedure and those subjects to whom alternative or additional treatment should be offered. We were interested in testing the hypothesis that tumour burden, and hence remission status immediately prior to transplant, is an important prognostic indicator of survival. We aggressively treated patients with conventional-dose salvage chemotherapy to maximum tumour response, and tested, by multivariate regression analysis, predictors of outcome post-transplant. We studied 81 consecutive patients with intermediate grade and immunoblastic NHL who achieved either a partial (PR) or complete remission (CR) following repetitive cycles of conventional-dose salvage therapy. Intensive therapy consisted of etoposide (60 mg/kg) and intravenous melphalan (160–180 mg/m²) with or without total body irradiation (TBI) followed by infusion of autologous unpurged bone marrow and/or blood cells. The predicted 4-year survival and progression-free survival (PFS) with a median follow-up of 37 months was 58% and 48% (95% confidence interval (CI) 37–55%), respectively. The only factor predictive of outcome was remission status at transplant (P = 0.0001). The PFS at 4 years for the CR group was 61% (95% CI 53–75%). In contrast, only 25% (95% CI 11–40%) of patients undergoing autotransplant in PR were progression free at 4 years. We conclude that remission status at transplant after maximum tumour reduction is a powerful prognostic indicator.     

Massive chemotherapy with autologous bone marrow transplantation in 50 cases of bad prognosis non-Hodgkin''s lymphoma

50 cases of advanced, intermediate (18) and high grade (32) non-Hodgkin's lymphoma (NHL) including 16 with Burkitt lymphoma have been treated with very high dose chemotherapy and autologous bone marrow transplantation (ABMT). These cases represent a retrospective analysis of the combined experience of a recently established collaborative group. 31 patients were treated with a protocol used in Lyon, 12 with that used in Marseille and seven with that used in London. Although the details of drug administration differed, each protocol was based on high dose alkylating agent (cyclophosphamide or melphalan), BCNU and cytosine arabinoside. 16 patients had drug resistant progressive NHL. Of these 11 responded to high dose treatment (nine CR, two PR). The duration of CR in this group was short (median 104d) and only one patient was in CR at 1 year. 19 patients had relapsed on previous therapy but were still responding to conventional rescue therapy. Following high dose therapy 47% of these patients are in continuous CR with a median time of observation of 300 d (73-962 d). Seven patients were partial responders to conventional induction therapy. Of these, six had a CR with high dose treatment and are still in CR (range 39-1230 d, median 200 d). Eight patients received high dose therapy as intensification after a long delay to CR with conventional treatment. Of these, four are alive and in remission 124-763 d after treatment. The high dose protocols produced significant morbidity with 25 patients (50%) having major or minor treatment-related complications, and there were seven treatment related deaths (14%). However, these results indicate that durable responses can be obtained with high dose chemotherapy in patients who have been heavily treated and indicate a role for this type of treatment at an earlier stage in advanced non-Hodgkin's lymphoma.     

Acute lymphoblastic leukemia in the elderly: The Edouard Herriot Hospital experience

Data on all patients with acute lymphoblastic leukemia (ALL) aged 60 or older, referred to our institution over a 18-year period, were studied to determine the incidence and range of clinical and biological subtypes, and the outcome of different therapeutic approaches. Sixty-nine ALL cases (median age: 68 years) were diagnosed between 1980 and 1998 (18% of all adult ALL seen during this period). Ten of them (14%) had a past history of previous malignancy. Karyotypic analysis was performed successfully in 42 cases. Ten patients were diagnosed as Philadelphia chromosome positive (Ph(+)) ALL. Immunophenotyping was performed in 63 cases. Fifty-six patients had B-cell lineage ALL. T lymphoid markers were observed only in 5 cases. Co-expression of myeloid markers was observed in 19% of tested cases. Five patients died before any chemotherapy could be given. All other patients received "curative" treatment according to different protocols used during the period of study. Overall complete remission (CR) rate of these patients was 62% (95% confidence interval (CI): 50-74%). Thirty-nine patients achieved CR after one course of chemotherapy and 4 patients after salvage therapy. Median disease-free survival (DFS) of the entire cohort was 8.3 months (95% CI: 5-12.8 months) and median overall survival was 7 months (95% CI: 6-10 months). In multivariate analysis, the presence of hemorrhage (P = 0.02) was a poor prognostic for CR achievement. Higher WHO performance status (P = 0.003) and the presence of hemorrhage (P = 0.01) at diagnosis were poor prognostics for overall survival. When patients were stratified into three groups according to the time of admission, survival appeared significantly longer for patients admitted between July 1992 and December 1998 (median overall survival at 10 months) than for patients admitted before July 1992 (P = 0.04). "Age-adapted" therapy appeared superior to "young adult-like" therapy in terms of CR rate (96% versus 60%; P = 0.007). However, "age-adapted" therapy did not show any advantage in terms of DFS or overall survival, making the difference in CR rates questionable. We conclude that the pejorative overall outcome in elderly ALL points to the need for new therapeutic trials taking into account the specific characteristics of ALL in this age group.     

Autotransplants for histologically transformed follicular non-Hodgkin's lymphoma

Histological transformation from a follicular non-Hodgkin's lymphoma (NHL) to a higher grade lymphoma carries a poor prognosis despite treatment with aggressive anthracycline-based chemotherapy. We retrospectively analysed 35 patients with histologically transformed NHL who underwent high-dose therapy and autotransplantation at our centre. Patients up to 65 years old were eligible for autotransplant at the time of transformation or with subsequent relapses, provided that chemosensitivity to a salvage regimen could be demonstrated. All patients received high-dose therapy [etoposide 60 mg/kg, melphalan 160 mg/m2 and fractionated total body irradiation (TBI) 12 Gy] followed by unpurged autologous bone marrow or blood stem cell rescue. Most patients (69%) had advanced stage disease (stages 3--4) at transformation and bone marrow involvement was common (49%). Twenty-six (74%) patients were in partial remission (PR) and nine (26%) in complete remission (CR) at the time of transplant. Median duration from transformation to transplant was 10.9 months (range, 5.2 months--4.6 years). At a median follow up of 52 months after autotransplant, 19 (54%) patients had died. Causes of death were progressive lymphoma in nine patients (26%), treatment-related mortality (TRM) in seven (20%) and myelodysplasia in three (8%). Only five patients in our cohort were > 60 years old, but all died as a result of treatment-related causes (mostly pulmonary infections). Five-year overall survival and progression-free survival from time of transplant were 37% and 36% respectively. Using multivariate analysis of factors including gender, age, stage, extranodal disease, disease bulk, B symptoms, number of prior therapies, relapse status and CR/PR status at transplant, only advanced age significantly predicted for survival from autotransplant (P = 0.002). Our survival data are comparable to previous reports of autotransplantation for transformed NHL and suggest a benefit over standard chemotherapy alone in selected patients. However, our high TRM cautions the use of aggressive therapy, including TBI, in patients over 60 years old.     

Lenalidomide plus rituximab can produce durable clinical responses in patients with relapsed or refractory,indolent non‐Hodgkin lymphoma

This phase II study evaluated the safety and efficacy of lenalidomide in combination with rituximab in patients with relapsed/refractory, indolent non‐Hodgkin lymphoma (NHL). Patients were treated with daily lenalidomide in 28‐d cycles and weekly rituximab for 4 weeks. Lenalidomide was continued until progression or unacceptable toxicity. Twenty‐two patients were assessed for FCGR3A polymorphisms. Thirty patients were enrolled; 27 were evaluable for response. The overall response rate (ORR) was 74% including 44% complete responses (CR); median progression‐free survival (PFS) was 12·4 months. The 13 rituximab refractory patients had an ORR of 61·5% (four CR/unconfirmed CR). The ORR was 77% in the 22 follicular lymphoma patients (nine CR/unconfirmed CR). At a median follow‐up time of 43 months, the median duration of response and time to next therapy were 15·4 and 37·4 months, respectively. Most common grade 3/4 adverse events were lymphopenia (45%), neutropenia (55%), fatigue (23%) and hyponatraemia (9%). The ORR and PFS in patients with low‐affinity FCGR3A polymorphisms (F/F and F/V) suggest that lenalidomide may improve the activity of rituximab in these patients. These data suggest that combining lenalidomide with rituximab can produce durable responses with acceptable toxicity in patients with indolent NHL.     

Autologous peripheral blood stem cell transplantation in children with non-Hodgkin’s lymphoma: a report from the Korean society of pediatric hematology-oncology

Recent development of stratified chemotherapeutic regimens has rapidly improved the survival rate of non-Hodgkin’s lymphoma (NHL) of childhood. Despite these improvements, the outcome for children with recurrent or refractory NHL remains dismal. We explored the use of high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (HDC/PBSCT) for children with either refractory or recurrent NHL, and we evaluated various factors influencing outcome of HDC/PBSCT. Thirty-three patients underwent HDC/PBSCT in 11 institutes were enrolled. All patients had refractory or recurrent NHL. Sex, stage at diagnosis, histologic subtype (lymphoblastic, Burkitt’s, and large-cell lymphoma), LDH level at diagnosis, disease status at transplantation, and preparative regimens for HDC/PBSCT were explored. In regard to the patients, six had Burkitt’s lymphoma, 13 had lymphoblastic lymphoma, and 14 had large-cell lymphoma. The 2-year event-free survival (EFS) was 59.1±9.3%. The EFS for Burkitt’s, lymphoblastic, and large-cell lymphoma was 66.7±27.2, 50.5±14.8, and 82.1±11.7%, respectively. In comparison with lymphoblastic and non-lymphoblastic lymphoma, the relative risk for lymphoblastic lymphoma was higher than the others (P=0.037). EFS between anaplastic large-cell and diffuse large-cell lymphoma was 100 and 55.6±24.9%, respectively (P=0.106). Status at transplantation was the most predictive factor for the survival after HDC/PBSCT (EFS for CR 70.8±9.5% vs non-CR 20.0±17.9%, P=0.008). Transplantation-related complications were minimal, and infection was the most prevalent complication. HDC/PBSCT is considered applicable to recurrent or refractory pediatric NHL patients safely and it could replace conventional chemotherapy. In this study, children with CR status at the time of HDC/PBSCT showed higher survival rate. However, refractory or recurrent lymphoblastic lymphoma patients showed dismal results. Therefore, new therapeutic modalities may be needed for this group of NHL patients.An erratum to this article can be found at     

大剂量化疗自体外周血干细胞移植生物治疗序贯疗法对67例非霍奇金淋巴瘤的疗效观察

目的评价大剂量化疗、自体外周血干细胞移植、生物治疗序贯疗法对非霍奇金淋巴瘤的疗效。方法2003年6月至2007年3月在第三军医大学新桥医院对67例中、高度恶性非霍奇金淋巴瘤(NHL)患者采用大剂量化疗、自体外周血干细胞移植、白介素-2(IL-2)生物治疗序贯治疗,观察其治疗效果和相关并发症。结果67例患者中,41例完全缓解期患者(NHL-CR),经上述序贯治疗,36例持续CR(87.8%),5例复发(RE,12.2%),其中1例死亡(2.4%);26例部分缓解患者(NHL-PR),达CR15例(57.7%),RE11例(42.3%),其中死亡5例(19.2%)。结论该序贯疗法治疗非霍奇金淋巴瘤安全有效,治疗前达到CR患者疗效更好。
