Abstract
In the past decade, the therapeutic arsenal for multiple sclerosis has expanded greatly. Newer more potent disease modifying therapies (DMTs) with varying mechanisms of actions are increasingly used early in the disease course. These newer DMTs include oral therapies (teriflunomide, dimethyl fumarate, fingolimod, siponimod, ozanimod, and cladribine) and infusion therapies (natalizumab, alemtuzumab, and ocrelizumab), and are associated with better control of disease activity and long-term outcomes in patients with MS compared to older injectable therapies (interferon beta and glatiramer acetate). However, they are associated with safety concerns and subsequent monitoring requirements. Adverse events are initially observed in phase 2 and 3 clinical trials, and further long-term data are collected in phase 3 extension studies, case series, and post-marketing reports, which highlight the need to periodically re-evaluate and adjust monitoring strategies to optimize treatment safety in an individualized approach.

Abstract
Although cladribine has been reported to be an active purine analog against indolent B-cell non-Hodgkin lymphoma (B-NHL), there are few reports of combination use of cladribine and rituximab. This multicenter phase II study evaluated the efficacy and toxicity of cladribine with rituximab (R-2-CdA) therapy in relapsed or refractory indolent B-NHL. Twenty patients with the median age of 58.5 yrs (range, 42-72) were enrolled and received R-2-CdA therapy from April 2005 to July 2007. The median number of prior regimens was 2 (range, 1-3), and fifteen patients (75%) were previously treated with rituximab-containing regimens. Disease histology included follicular lymphoma in 16 patients, MALT lymphoma in two patients, nodal marginal B-cell lymphoma in one patient, and lymphoplasmacytic lymphoma in one patient. The overall response rate (ORR) was 90%, with a complete response rate (CRR) of 70%. Estimated median progression-free survival (PFS) time was 22.4 months (95%CI, 10.9-32.6 months) at a median follow-up time of 27 months (range, 12-43). Two-year PFS and 2-yr overall survival (OS) were 52.6% (95%CI, 31.0-73.2%) and 89.5% (95%CI, 66.1-97.3%), respectively. Grade 3 or grade 4 toxicities were neutropenia in 74% and thrombocytopenia in 11%. R-2-CdA therapy was demonstrated to have a high activity with durable PFS and acceptable toxicity in relapsed or refractory indolent B-NHL mostly pretreated with rituximab-containing therapy. Although a large-scale trial is needed for confirmation, R-2-CdA therapy could be a good salvage therapy option in relapsed or refractory indolent B-NHL.

Abstract
Before the contemporary development of rationally designed antineoplastic therapies, cladribine was identified as a lymphocyte-specific agent. Its profound impact on the natural history of hairy cell leukemia, with responses approaching 100% and a median duration of response of nearly a decade after only a single 7-day course, is well known and revolutionized the treatment of hairy cell leukemia. However, cladribine's impressive activity in other lymphoproliferative disorders has been generally underappreciated. Multiple single-arm phase 2 trials have demonstrated cladribine's potency across the full spectrum of lymphoid malignancies. In a limited number of phase 3 trials and cross-study analyses, cladribine compared favorably with fludarabine, another purine nucleoside analog that is more commonly used in the treatment of indolent lymphoid malignancies. Cladribine has been noted to have particular activity among lymphoid disorders with few effective therapies, specifically, chronic lymphocytic leukemia, lymphoplasmacytic lymphoma, marginal zone lymphoma, and mantle cell lymphoma. Recently approved novel agents may act in synergy with cladribine for these conditions and should be incorporated into future clinical studies.

Abstract
BACKGROUND The objective of this study was to determine the efficacy and toxicity of 2-chlorodeoxyadenosine (2-CdA) in patients with untreated, indolent non-Hodgkin lymphoma (NHL). METHODS For this multicenter, single-arm, Phase II study, 44 patients with treatment-naive, stage III or IV, indolent NHL (International Working Formulation subtypes A, B, and C) were enrolled. Patients received 0.14 mg/kg per day of 2-CdA as a 2-hour bolus infusion for 5 consecutive days every 28 days until maximal response or a total of 6 cycles. RESULTS Thirty-eight patients were eligible for response evaluation. The overall response rate was 100% (95% confidence interval [95% CI], 90.8-100%), and the complete response rate was 31.6% (95% CI, 17.5-48.7%). In the intent-to-treat population, the median failure-free survival was 2.0 years (95% CI, 1.3-3.4 years), and the overall survival rate was 7.0 years (95% CI, 4.3-9.4 years). Six patients had sustained remissions that lasted a median of 8.7 years (range, from 5.9 years to > or =11 years). Although 68% of patients experienced at least 1 grade 3 or 4 event, consisting primarily of myelosuppression, severe infections were rare, with only 8 grade 3 infections. Four late malignancies (prostate adenocarcinoma, ductal carcinoma in situ, and myelodysplasia) and 4 patients with large cell transformation were reported. CONCLUSIONS 2-CdA is an active, well-tolerated therapy for patients with untreated, indolent NHL.

Abstract
A multicenter trial was performed to confirm the therapeutic efficacy and the toxicity profile of the combination of cladribine, cyclophosphamide and prednisone in low-grade non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL). Twenty-three adults with previously treated (61%) or untreated (39%) NHL International Working Formulation A or Binet B and C CLL were administered cladribine 0.1 mg/kg/day as a subcutaneous bolus for 5 days, intravenous cyclophosphamide 500 mg/m2 on day 1, and oral prednisone 40 mg/m2 on days 1-5, every 4 weeks. Unexpected early hematological toxicities led to dose modifications for pretreated patients who received cladribine for 3 days only up to a maximum of five courses. Responses were observed in 75%, with 7 patients obtaining a complete clinical and hematological response. Median duration of complete response was 9 months. Median time to progression or relapse was 31 months. Myelosuppression and infections were dose limiting whereas posttreatment complications, including fatalities, resulted from infections. Median overall survival time from trial entry was 60 months. Activity of the combination of cladribine, cyclophosphamide and prednisone was confirmed. However, in the specific setting of a multicenter trial, unexpected fatal infectious episodes occurred in pretreated patients. Great caution is thus required in these susceptible patients and the routine use of corticosteroids should probably be abandoned.

Abstract
BACKGROUND In vitro studies have shown synergistic or additive interactions between rituximab and purine nucleoside analogues. The results of recent clinical trials seem to confirm these preclinical observations. METHODS For the current study, the authors evaluated the feasibility, efficacy, and toxicity of combined regimens that consisted of either rituximab plus cladribine (2-CdA) (the RC regimen) or RC plus cyclophosphamide (the RCC regimen) in the treatment of patients with heavily pretreated, indolent lymphoid malignancies. Fifty-four adult patients with recurrent or refractory, low-grade non-Hodgkin lymphoma (LG-NHL) and B-cell chronic lymphocytic leukemia (B-CLL) were treated according to the RC/RCC regimens. The RC protocol consisted of intravenous rituximab at a dose of 375 mg/m(2) on Day 1 and 2-CdA at a dose of .12 mg/kg per day on Days 2 through 6. The RCC protocol consisted of rituximab at a dose of 375 mg/m(2) on Day 1, 2-CdA at a dose of 0.12 mg/m(2) on Days 2 through 4, and intravenous cyclophosphamide at a dose of 250 mg/m(2) per day on Days 2 to 4. The RC/RCC courses were repeated at 4-week intervals. RESULTS Thirty-three patients with B-CLL, 12 patients with LG-NHL and 9 patients with mantle cell lymphoma (MCL) entered the study. Thirty-three patients (61%) had recurrent disease after prior therapy, and 21 patients (39%) had refractory disease. Thirty-one patients were treated on the RC regimen, and 23 patients were treated on the RCC regimen. Six patients (11%) achieved a complete response, and 33 patients (60%) achieved a partial response. The median failure-free survival of responders was 10.5 months. The treatment revealed tolerability, with episodes of severe neutropenia (Grade 3 and 4 [according to World Health Organization criteria]) observed in 6 patients (11%), episodes of Grade 3 and 4 infections observed in 11 patients (20%), and episodes of Grade 3-4 thrombocytopenia observed in 4 patients (7%). CONCLUSIONS The RC and RCC regimens were highly effective and well tolerated modalities of treatment in heavily pretreated patients with indolent lymphoproliferative disorders.

Abstract
We conducted a phase II study to evaluate the efficacy and safety of cladribine (2-chlorodeoxyadenosine [2-CdA]) for patients with refractory or relapsed indolent B-cell lymphoma or mycosis fungoides. Forty-five patients were enrolled, and 43 patients, including 34 with follicular lymphoma, were eligible. 2-CdA was given by continuous intravenous infusion at a dose of 0.09 mg/kg daily for 7 consecutive days, and this schedule was repeated every 4 weeks up to a maximum of 6 cycles. The overall and complete response rates were 58.1% (25/43; 90% confidence interval, 44.5%-70.9%) and 14.0% (6/43), respectively. The disease progression-free proportions of all 43 eligible and all 25 responding patients at 2 years were 30.3% and 48.1%, respectively. Neutropenia and thrombocytopenia of grade 3 or 4 were observed in 53.3% and 37.8% of patients, respectively, with prolonged cytopenia observed in patients with increased numbers of treatment cycles. Nonhematologic toxicities of grade 3 or greater included diarrhea, arrhythmia, malaise, and gastrointestinal bleeding in 1 patient each, an increase in glutamic-pyruvic transaminase level in 2 patients, and infection in 5 patients. Two treatment-related deaths were observed. Four patients developed myelodysplastic syndrome (MDS) at 13 months to 2 years after completion of the 2-CdA treatments. 2-CdA is an active agent with acceptable toxicity for refractory or relapsed indolent lymphoma; however, prolonged myelosuppression and the potential development of MDS should be carefully monitored.

Abstract
The term indolent in describing a non-Hodgkin's lymphoma (NHL) generally refers to a group of B-cell NHLs composed of predominantly small cells that make up several categories, including follicular lymphoma, small lymphocytic lymphoma, and lymphoma of mucosa-associated lymphoid tissue. Most patients with follicular lymphoma respond to therapy, and the average survival time in large series is approximately 10 years. Patients who achieve a complete remission with initial treatment have an approximately 25% chance of remaining free of disease for 10 years. However, this means that more than 80% of patients will require salvage therapy. Cladribine is a newer purine analogue and is of particular interest because it is resistant to deamination by adenosine deaminase. It is cytotoxic to both proliferating and resting lymphocytes, making it an attractive agent for the treatment of indolent NHL. In this review article, we summarize the current treatment approaches for indolent NHL and the results of cladribine monotherapy studies in Japan and cladribine studies in Germany that have focused on a combination therapy with mitoxantrone. Cladribine is a potent inhibitor of DNA repair. The combination of a DNA-damaging agent with an inhibitor of DNA repair constitutes the rationale for combining cladribine with mitoxantrone. A German study has demonstrated that the combination of reduced-dose cladribine and mitoxantrone is a highly active regimen with favorable toxicity profiles. Cladribine is highly effective as a single agent and in combination with mitoxantrone in the treatment of indolent NHL, and its availability broadens the range of therapeutic options for indolent NHL.

Abstract
Zevalin (ibritumomab tiuxetan; IDEC Pharmaceuticals Corporation, San Diego, CA, USA) was approved by the United States Food and Drug Administration on February 19, 2002, following 9 years of clinical development. Six clinical studies supported the Zevalin Biologics License Application. The Zevalin regimen is indicated for the treatment of patients with relapsed or refractory low-grade, follicular, or transformed B-cell non-Hodgkin's lymphoma (NHL), and for those with follicular NHL refractory to Rituxan (rituximab, MabThera; IDEC Pharmaceuticals Corporation, San Diego, CA and Genentech, South San Francisco, CA). In the year following FDA approval, approximately 1300 patients were treated in clinical trials or with the commercially available product.

Abstract
Adult T-cell leukemia-lymphoma (ATL) is a retrovirus-associated T-cell malignancy with an extremely poor prognosis; the median survival time of ATL patients with the acute or lymphoma type is less than 1 year with various combination chemotherapies. Cladribine (2-chlorodeoxyadenosine; 2-CdA), a purine analog resistant to degradation by adenosine deaminase, has shown definitive clinical activity against various lymphoid malignancies, including hairy cell leukemia, indolent lymphoma, and cutaneous T-cell lymphoma. An in vitro study showed the sensitivity of T-lymphoblastoid cell lines to cladribine, and a preceding Japanese phase I study of cladribine showed that 1 refractory patient with ATL achieved an objective response. To evaluate the therapeutic efficacy of cladribine in treating ATL, we conducted a multicenter phase II study. The plan was to administer cladribine to 30 ATL patients as 0.09 mg/kg per day by 7-day continuous intravenous infusion every 4 weeks for up to 3 courses. Before the planned interim analysis, 16 patients with relapsed or refractory ATL were enrolled, 15 of whom were eligible. Only 1 of the 15 eligible patients showed an objective response (overall response rate, 7%; 90% confidence interval, 0% to 28%), and 11 patients (73%) showed progressive disease, mostly during the first course of treatment. Because the upper limit of the 90% confidence interval of the overall response rate did not reach 30% in the interim analysis, the Independent Monitoring Committee advised us to discontinue patient enrollment. In conclusion, cladribine is not worthy of further investigation for the treatment of ATL.

Abstract
Indolent non-Hodgkin's lymphoma is the commonest form of lymphoma in the USA and Europe, with a long natural history with multiple responses and relapses. Indolent lymphomas include follicular lymphomas (the more frequent subtype), immunocytoma, and small lymphocytic lymphomas according to the Revised European-American Lymphoma classification. The tendency has been to use simple oral medication until patients have more advanced aggressive disease but new agents such as the purine analogues have led to re-evaluation of this approach. The newer purine analogues -- fludarabine, 2-chlorodeoxyadenosine (cladribine) and deoxycoformycin (pentostatin) -- are a group of potently lymphotoxic antimetabolite molecules. Their activity in the indolent non-Hodgkin's lymphomas, in particular in the follicular subtype, may be due to their unique ability as antimetabolites to inhibit resting as well as dividing cells. Within the last decade they have moved from salvage therapy to front-line studies. Further insight into the mechanism of action of the purine analogues will to lead to further advances in this group of diseases.

Abstract
The interactions of 2-chlorodeoxyadenosine (2-CdA, cladribine) and three anthracyclines: doxorubicin (DOX), idarubicin (IDA) and mitoxantrone (MIT) were evaluated on murine leukemias P388 and L1210. Prolongation of survival time of animals receiving drugs in combination compared to mice treated with drugs in monotherapy was tested. We have also evaluated interactions of the cytostatics on murine leukemias in vitro by measuring their inhibitory effects on P388 and L1210 cell proliferation. We have observed a synergistic effect of MIT and IDA in combination with 2-CdA on P388 leukemia resulting in an increase of life span (ILS)=226% in case of MIT+2-CdA and ILS=126% in the case of IDA+2-CdA, whereas 2-CdA used as a sole drug resulted in an ILS=47%. The survival time of animals inoculated with P388 leukemic cells and treated with DOX+ 2-CdA was similar to ILS gained by DOX monotherapy (178% and 200% respectively). The mice bearing L1210 leukemia receiving combined chemotherapy lived significantly longer than the animals on single agent regimens. The animals treated with schedule 2-CdA+MIT lived significantly longer (P=0.004) as compared to the groups receiving drugs in monotherapy (ILS of 2-CdA+MIT group=60%, ILS of MIT group 33%, and 2-CdA group 33%). Finally, combination of DOX or IDA with 2-CdA resulted in ILS =73% (2-CdA+DOX regimen), and ILS=60% in case of 2-CdA+IDA regimen, which is significantly higher than ILS gained on monotherapy schedules. In vitro tests revealed that all tested anthracyclines enhance the antiproliferative activity of 2-CdA against L1210 and P388 leukemic cells (P<0.05). Our study has shown that all anthracyclines potentiate 2-CdA antileukemic activity, both in vivo and in vitro. It failed however to point the best one to be combined with cladribine. We suggests that further clinical trials with such combinations are needed.

Abstract
PURPOSE To assess the efficacy and toxicity of liposomal daunorubicin administered as a two-hour intravenous infusion to patients with relapsed or refractory non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS Eligible patients had relapsed or refractory NHL with measurable or evaluable disease, and low grade, select intermediate grade, or mantle cell pathologic types. Prior exposure to an anthracycline or anthracenedione was allowed. Liposomal daunorubicin at a dose of 100 mg/m2 was given intravenously over a minimum of 120 minutes every 3 weeks. as a single agent. RESULTS Thirty-three patients were accrued: twenty-three (70%) had low-grade histologies; six (18%) had intermediate-grade histologies (follicular large-cell and diffuse small cleaved); and four (12%) patients had mantle-cell lymphoma. Eighteen (55%) had received two or more prior regimens; fourteen (42%) received a prior anthracycline. A median of six cycles of liposomal daunorubicin were administered (range 1-15). Of 31 patients evaluable for response, 2 complete and 10 partial remissions were documented for a major response rate of 39% (95% confidence interval (CI): 22%-58%). The median duration of response was 19.5 months (range 4.3-41.1+). Six responders (50%) had received a prior anthracycline; one responder had mantle-cell histology. The major toxicities were grade 3 or 4 neutropenia in 26 patients (79%), mild to moderate nausea in 22 (67%), and fatigue in 16 (48%). CONCLUSIONS Liposomal daunorubicin at 100 mg/m2 every three weeks has activity in patients with relapsed or refractory NHL, including patients with prior exposure to an anthracycline. Further studies of liposomal daunorubicin in combination with other agents are warranted.

Abstract
PURPOSE The purpose of this article is to review the historical development and recent advances in the application of monoclonal antibodies for the treatment of lymphoma. OVERVIEW The history of clinical applications of monoclonal antibodies has been intertwined with that of lymphomas. The first report of a complete remission in 1981 described a patient with follicular lymphoma who was treated with a murine anti-idiotype antibody. Later that decade there appeared additional encouraging reports of radiolabeled monoclonal antibodies, immunotoxins, and other antibodies with antitumor effects against lymphoma and chronic lymphocytic leukemia. Monoclonal antibodies as a treatment of malignancy became reality in late 1997 when the US Food and Drug Administration approved the anti-CD20 chimeric monoclonal antibody rituximab for the treatment of B-cell lymphoma. Since that time an anti-CD25 monoclonal antibody (dacliximab) and an anti-CD25 immunotoxin fusion product (denileukin diftitox) have become clinically available. Several radio- labeled antibodies, including the murine anti-CD20 products (131)I-tositumomab and (90)Y-ibritumomab tiuxetan, are in advanced stages of clinical testing as are other unlabeled monoclonal antibodies with antilymphoma activity. Other antilymphoma immunotoxins that react with CD25, CD19, and CD22 also have shown promise. CLINICAL IMPLICATIONS The therapeutic arsenal against lymphoma has been significantly changed by the addition of these antibody products that are active as single agents, and are synergistic, additive, or both with other antilymphoma treatments.

Abstract
We report two patients with primary cutaneous B-cell lymphoma who were treated with rituximab, a new anti-CD20 monoclonal antibody. The first patient, who had a diffuse large B-cell lymphoma of the lower leg, achieved an 85% improvement. The second patient, who had a primary cutaneous B-cell lymphoma, which had undergone high-grade transformation and systemic spread, achieved a minor response of approximately 30%. Both patients subsequently relapsed. The first patient achieved complete clearance with a second course of rituximab given with systemic chemotherapy, but again relapsed. Treatment with rituximab has been reported to produce response rates of 48% in relapsed systemic low-grade or follicular lymphoma, but there are no previous reports of the use of rituximab in primary cutaneous B-cell lymphoma.

Abstract
Because of their substantial in vitro synergy, we conducted a dose-escalation study of cyclophosphamide (CP) added to 2-chloro-2'-deoxyadenosine (CdA) in patients with previously treated chronic lymphocytic leukemia and non-Hodgkin's lymphoma. CdA was given at a fixed dose (5.6 mg/m2/day) as a 2-h intravenous (i.v.) infusion, immediately followed by a 1-h i.v. infusion of CP, for 3 days. The initial daily CP dose was 200 mg/m2, and was escalated by 100 mg/m2 increments in successive cohorts of three to six patients to determine the maximum-tolerated dose (MTD). Additional patients were included at the MTD to extend toxicity and response analysis. Twenty-six patients received 68 cycles of chemotherapy. The MTD of CP after CdA 5.6 mg/m2, was 300 mg/m2. Acute neutropenia was the dose-limiting toxicity of this regimen, which was otherwise well tolerated. Delivery of repeated cycles was not feasible in eight patients (31%) because of prolonged thrombocytopenia. Severe infections were seen in three of 68 cycles (4%). The overall response rate was 58% (15 of 26; 95% CI, 36-76%), with 15% complete responses and 42% partial responses. These data show the feasibility of the association of CdA with CP. Given the response rate observed, further studies of this regimen are warranted in untreated patients, in particular with chronic lymphocytic leukemia and with Waldenström macroglobulinemia.

Abstract
BACKGROUND Oncologic literature cites many different definitions of critical response measurements. PATIENTS AND METHODS Response criteria (RC) for non-Hodgkin's lymphoma (NHL) were developed by lymphoma experts, endorsed by international lymphoma clinicians, and applied to a 166-patient rituximab (Rituxan, MabThera) trial by a third-party, blinded panel of NHL experts (LEXCOR). Retrospectively, we analyzed this data using variations of the original RC and comparing with recently published RC. RESULTS The definition of a 'normal' lymph node affected the complete response (CR) rate (< or = 1.0 x 1.0 cm, 6%; < or = 1.5 x 1.5 cm, 18%; < or = 2.0 x 2.0 cm, 28%); overall response rate (ORR) was not affected. CR rates increased progressively without > or = 28 days response confirmation: 12% vs. 6% (< or = 1.0 x 1.0 cm), 26% vs. 18% (< or = 1.5 x 1.5 cm), and 36% vs. 28% (< or = 2.0 x 2.0 cm). CR rate and duration of response (DR) were unaffected when only the six largest, rather than all lesions, were measured. When the new RC were applied, CR rate (32%) was higher and DR (13.9 months) and time to progression (15.6 months) were shorter in complete responders. CONCLUSIONS Standard RC must be consistently and rigorously applied for accurate comparisons between studies.

Abstract
BACKGROUND It is unclear whether the purine analogs fludarabine (Flu) and cladribine (CdA) are non-resistant. PATIENTS AND METHODS Sixty patients with relapsed or refractory low-grade NHL were randomly allocated to initial treatment with either Flu 25 mg/m2, or CdA 0.14 mg/kg, each for five consecutive days every four weeks. Upon treatment failure, eligible patients were crossed over to the other study drug. RESULTS Overall response and CR were 68% and 48% with Flu, and 72% and 38% with CdA, respectively. For responders, actuarial three-year progression-free survival was 58% with Flu and 52% with CdA. Treatment with both drugs was well tolerated, with toxic effects primarily hematological. Two patients (8%) in the Flu group and 15 patients (47%, P = 0.001) in the CdA group were taken off study because of persistent hematological toxicity. After cross over, none of seven refractory patients responded, while eight of nine previously responsive patients achieved second responses. CONCLUSIONS Our study confirms that Flu and CdA have similar response rates and durations. However, further studies are required to optimize the CdA schedule and dosage in order to ameliorate its toxic profile while maintaining antitumor activity. The two drugs appear to be cross-resistant.

Abstract
Aim of this multicenter-study was to evaluate rate and duration of remissions and to examine toxicity of cladribine in low-grade lymphomas as first-line therapy or in first relapse using intermittent 2-hour-infusion of cladribine. A total of 294 courses, median of 5 courses per patient, were administered to 66 evaluable patients (53 previously untreated, 13 relapsed) with 5 mg/m2 cladribine given as intermittent 2-hour-infusion over 5 consecutive days for a maximum of 6 cycles every four weeks. Entities: 26 follicle center, 20 lymphoplasmacytoid, 12 mantle cell, 6 T-cell, 2 marginal zone lymphomas. Fifty of 66 patients responded to cladribine corresponding to an overall response rate of 76% (95% confidence interval (95% CI): 64%-85%) with 38% CR (95% CI: 26%-51%) and a median time of remission duration of 23 months (range 6-45+). The overall survival rate at 48 months was 72%. For 49 previously untreated patients with B-cell lymphomas the overall response rate was 86% (95% CI: 73%-94%) with a high CR rate of 43% (95% CI: 29%-58%). Response rate for the group of 23 previously untreated patients with follicle center lymphomas was high with 96% overall response (95% CI: 78%-100%) and 57% CR rate (95% CI: 34%-77%). Cladribine also showed activity in patients with mantle cell lymphomas achieving a response rate of 58% (95% CI: 28%-85%). Myelosuppression was the major toxicity with 17% neutropenia grade 3 and 4. Thrombocytopenia was rare with only 2% grade 3 and 4. A prolonged CD4-lymphocytopenia was observed in all patients. Life threatening complications were not observed. These results confirm the major single-agent activity of cladribine in a large cohort of patients with untreated low-grade lymphomas using the intermittent 2-hour-infusion dosage-regimen. To improve treatment results furthermore, cladribine should be combined with other agents active in low-grade lymphomas.

Abstract
Adverse events are common in the elderly when they undergo potent chemotherapy and the reasons for this are various. Therefore, chemotherapy for elderly patients with non-Hodgkin's lymphoma (NHL) must differ from that for non-elderly patients. Age is one of the poor prognostic factors for NHL and the main reason for this is reduced antitumour effect due to decreased dose and increased adverse effects. However, many of these elderly patients also die from causes other than lymphoma. The usual approach to the treatment of indolent NHL is to use drugs with few adverse effects such as nucleoside analogs. Multidrug therapy is used for intermediate grade NHL and the most commonly used regimen is CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone). In recent years, many clinical trials have been performed in elderly patients with NHL. The results of these trials indicate that a significantly better prognosis is achieved with anthracycline (cytostatic antibiotics) containing regimens. The elderly population will continue to grow and so it is necessary to establish more effective treatment options for NHL in the elderly.

Abstract
The feasibility of combining cladribine with cyclophosphamide and prednisone in the management of indolent lymphoid malignancies was determined. Nineteen patients [nine chronic lymphocytic leukaemia (CLL), seven non-Hodgkin's lymphoma (NHL) and three macroglobulinaemia (M))] received cladribine 0.1 mg kg(-1) per day as a subcutaneous bolus injection on days 1-3 (up to 5 injections) with intravenous cyclophosphamide 500 mg m(-2) on day 1 and oral prednisone 40 mg (m-2) on days 1-5 at 4-weekly intervals up to a maximum of six courses. A total of 80 courses were given. Overall response rate was 88%, with four patients achieving a complete clinical and haematological response and 12 achieving a partial response. Neutropenia WHO grade 4 in two patients and WHO grade 3 infection in one patient were the limiting toxicities on treatment. During the follow-up, WHO grade >3 haematological complications occurred in five patients and WHO grade >3 non-haematological complications in five patients. There were no treatment-related deaths. This study demonstrates the feasibility of the cladribine/cyclophosphamide/prednisone (CCP) combination that appears highly active and safe in the management of indolent lymphoid malignancies.

Abstract
BACKGROUND Cladribine (2-chlorodeoxyadenosine) is a purine nucleoside analog with cytotoxic activity against both resting and proliferating cells. Clinical studies with cladribine have reported antitumor activity against various hematologic malignancies. METHODS The authors studied responses to cladribine among patients with low and intermediate grade non-Hodgkin's lymphoma that had been refractory to or relapsed after prior chemotherapy. Cladribine was given intravenously over 2 hours at a dose of 0.14 mg/kg daily for 5 consecutive days, repeated every 4 weeks. RESULTS Twenty-eight patients (16 males, 12 females) with a median age of 58 years (range, 41-75 years) were accrued. Twenty-three patients had low grade and 5 had intermediate grade lymphoma. Stage IV disease was present in 22 (79%), and 17 (61%) had systemic B-symptoms. The majority (57%) had received 2 or more prior chemotherapy regimens (median, 2; range, 1-5); 6 had had prior fludarabine therapy. Major responses were documented in 32% (9 of 28 patients), with 4 complete remissions (CR) and 5 partial remissions (PR) after a median of 4 cycles (range, 1-9). One CR occurred in one patient with intermediate grade diffuse large cell lymphoma, and three of six patients who had had prior fludarabine therapy experienced CR or PR with cladribine. Severe hematologic toxicities included reversible neutropenia, protracted thrombocytopenia, and lymphopenia. Other reported adverse effects included mild-to-moderate fatigue, nausea, and diarrhea. CONCLUSIONS Cladribine is an active single agent in the treatment of patients with refractory or relapsed advanced stage indolent lymphoma, with major responses in one third of patients.

Abstract
Therapy-related myelodysplastic syndrome (t-MDS) and acute nonlymphocytic leukemia (t-ANLL) are dramatic complications of cancer chemotherapy. Drugs like plant alkaloids or antimetabolites have not been reported to cause either t-MDS or t-ANLL. Monosomy 7(-7) and trisomy 8(+8) are among the most common abnormalities in myelodysplastic syndromes. Both abnormalities in two different clones of the same patient are very rarely reported. Such a myelodysplastic syndrome occurring shortly after treatment with an antimetabolite, the adenosine analogue cladribine (1-chlorodeoxadenosine), and involved field radiotherapy is reported here.

Abstract
IDEC-C2B8 is a chimeric monoclonal antibody (MoAb) directed against the B-cell–specific antigen CD20 expressed on non-Hodgkin's lymphomas (NHL). The MoAb mediates complement and antibody-dependent cell-mediated cytotoxicity and has direct antiproliferative effects against malignant B-cell lines in vitro. Phase I trials of single doses up to 500 mg/m2 and 4 weekly doses of 375 mg/m2 showed clinical responses with no dose-limiting toxicity. We conducted a phase II, multicenter study evaluating four weekly infusions of 375 mg/m2 IDEC-C2B8 in patients with relapsed low-grade or follicular NHL (Working Formulation groups A-D). Patients were monitored for adverse events, antibody pharmacokinetics, and clinical response. Thirty-seven patients with a median age of 58 years (range, 29 to 81 years) were treated. All patients had relapsed after chemotherapy (median of 2 prior regimens) and 54% had failed aggressive chemotherapy. Infusional side effects (grade 1-2) consisting of mild fever, chills, respiratory symptoms, and occasionally hypotension were observed mostly with the initial antibody infusion and were rare with subsequent doses. Peripheral blood B-cell depletion occurred rapidly, with recovery beginning 6 months posttreatment. There were no significant changes in mean IgG levels and infections were not increased over what would be expected in this population. Clinical remissions were observed in 17 patients (3 complete remissions and 14 partial remissions), yielding an intent to treat response rate of 46%. The onset of these tumor responses was as soon as 1 month posttreatment and reached a maximum by 4 months posttreatment. In the 17 responders, the median time to progression was 10.2 months (5 patients exceeding 20 months). Likelihood of tumor response was associated with a follicular histology, with the ability to sustain a high serum level of antibody after the first infusion, and with a longer duration of remission to prior chemotherapy. One patient developed a detectable but not quantifiable immune response to the antibody that had no clinical significance. IDEC-C2B8 in a dose of 375 mg/m2 weekly for 4 weeks has antitumor activity in patients with relapsed low-grade or follicular NHL. Results with this brief, outpatient treatment compare favorably with results with standard chemotherapy, and IDEC-C2B8 has a better safety profile. Further studies evaluating IDEC-C2B8 in other types of lymphoma either alone or combined with chemotherapy are warranted.

The efficacy and toxicity of 2-chlorodeoxyadenosine (2-CdA) in cutaneous T-cell lymphoproliferative disorders was examined. Between February 1991 and April 1996, 25 patients with relapsed or refractory cutaneous T-cell lymphoproliferative disorders (24 mycosis fungoides or Sezary syndrome, one Ki-1+ anaplastic large cell lymphoma) were treated with 2-CdA initially administered by continuous intravenous infusion at a dose of 0.1 mg/kg/d for 7 days (13 patients). The infusion duration was subsequently reduced to 5 days (9 patients) because of prohibitive hematologic toxicity. Three patients were treated at the same daily dose by bolus injection over two hours for 5 days. Cycles were administered at 28 day intervals. Seventeen patients received more than one cycle. An overall response rate of 24% was achieved. Three patients (12%) had a complete response with a median duration of 4.5 months (range, 2.5 to 16). Three (12%) had a partial response with a median duration of 2 months (range, 2 to 4). Nineteen patients (76%) had no response. The most significant toxicities encountered were myelosuppression (64%) and infectious complications (64%). 2-CdA has activity as a single agent in patients with previously treated relapsed T-cell lymphoproliferative disorders.

Abstract
The purpose of our study was to determine the efficacy of 2-chlorodeoxyadenosine (2-CdA) administered in 2-hour intravenous infusions in previously treated patients with low grade non-Hodgkin's lymphoma (LGNHL). We treated 94 LGNHL patients with 2-CdA at a dosage of 0.12 mg/kg/24h in 2-hour intravenous infusion for 5 consecutive days. The treatment consisted of from 1 to 7 courses (median 3), repeated usually at monthly intervals. All patients were refractory to or relapsed after standard chemotherapy. Of these 94 patients 78 (83%) had clinical stage IV of the disease. Complete response (CR) was obtained in 12 (12.8%) and partial response (PR) in 36 (38.3%) giving an overall response rate of 51.1%. In 12 (12.8%) grade 4 thrombocytopenia with haemorrhagic diathesis was noted, grade 4 neutropenia was observed in 12 (12.8%) and infections complicated the course of treatment in 38 (40.4%) patients. 2-CdA treatment was the cause of death of 3 patients. The results of our study show that 2-CdA given in 2-hour infusions is an effective agent in advanced, heavily pretreated patients with LGNHL.

Abstract
BACKGROUND The promising results of fludarabine (FLU) in chronic lymphocytic leukemia have prompted its extensive evaluation in low-grade non-Hodgkin's lymphoma (LG-NHL). Its different mechanisms of action make FLU an attractive partner for combination with other cytostatic agents. PATIENTS AND METHODS We used a three-drug combination of FLU (25 mg/m2 i.v. on days one to three), mitoxantrone (10 mg/m2 i.v. on day one) and prednisone (40 mg given orally on days one to five) (FMP) to treat 48 patients with recurrent LG-NHL. RESULTS Of the 48 patients, 17 (35%) achieved complete responses (CR), 23 (48%) partial responses, while the remaining 8 (17%) showed no benefit from the treatment. The risk of lower CR rate was significantly correlated with the presence of advanced stage (IV) (P = 0.01), the number of previous regimens (> or = 3) (P = 0.006), and the follicular histologic subtype (P = 0.02). The major toxic effects observed were neutropenia and infections; there was only one fatality, due to drug-related side effects. CONCLUSIONS These data confirm the significant efficacy of the FMP fludarabine-mitoxantrone combination regimen in obtaining a good remission rate with moderate toxicity in a particular subset of recurrent LG-NHL.

Abstract
In order to evaluate efficacy and safety of 2-chlorodeoxyadenosine (2-CdA) as primary therapy of low grade non Hodgkin's lymphoma, a phase II trial of 2-CdA was initiated in patients with previously untreated advanced low grade lymphoma. Fourteen previously untreated patients with stage III and IV low grade lymphoma were enrolled. Patients received 2-CdA 0.1 mg/kg/d by continuous infusion for 7 days every 28 days, for 1-6 cycles of therapy (median 3.5). Results showed one complete response and nine partial responses for an overall response rate of 75%. Until now there have only been three responding patients who have had progressive disease, with a median follow-up time of 18 months. The major toxicity was bone marrow suppression and nine patients stopped therapy prior to a planned six cycles because of prolonged cytopenias, primarily thrombocytopenia. Fifteen of 50 cycles of therapy were associated with neutropenic febrile episodes and there was one septic death secondary to Listeriosis. It seems from this small group of patients that 2-CdA is an active agent in previously untreated low grade lymphoma. Myelosuppression is cumulative and limits the number of cycles of therapy which can be given. Future exploration of different doses or schedules of this active agent is warranted.

Abstract
2-Chlorodeoxyadenosine (2-CdA) is a purine analog with cytotoxic activity on both resting and cycling lymphocytes which has been used as salvage therapy in advanced/resistant chronic lymphoproliferative disorders. In our study 39 patients (19 B-CLL, 5 B-PLL, 9 low-grade B-NHL, 5 CTCL and 1 high-grade T-NHL) who relapsed or became resistant after 1-4 chemotherapy regimens were treated with 2-CdA 6 mg/m2 per day by 2 h infusion for 5 d every 28 d. The overall clinical response rate, including complete remission (CR) and partial remission (PR), was 66%. Two of 19 (10%) B-CLL patients achieved a CR lasting 9 months, while 11/19 B-CLL (58%) and 4/5 B-PLL (3 B-PLL/B-CLL and 1 B-PLL) (80%) achieved a PR. Interestingly, 5 of 6 patients who had been previously treated with fludarabine obtained a clinical response (2 CR and 3 PR). One of 9 (11%) low-grade B-NHL patients achieved a CR and relapsed after 26 months, and 5/9 (55%) achieved a PR. One of 5 (20%) CTCL achieved a CR lasting 32 months, while 2/5 (40%) achieved a PR. The overall mean duration of PR was 7.4 months and no differences were observed among different groups of patients. Toxicity was acceptable, as only a transient severe hematological impairment was observed in 20% of the patients while nonhematological toxicity was not documented. Two patients died because of bacterial pneumonia, 1 of meningitis due to Listeria and 9 from progression of the disease. In conclusion, treatment with 2-CdA in heavily pretreated patients with chronic lymphoproliferative disorders is well tolerated and obtains high response rates, even in patients relapsed after treatment with fludarabine.

Abstract
Histologically indolent lymphomas which represent 40-50% of all non-Hodgkin's lymphomas encompass small lymphocytic lymphomas, follicular lymphomas and other entities more recently described such as mantle cell and marginal zone lymphomas. Their management has benefited from new drugs such as interferon alpha the purine analogues and new treatment modalities especially autologous stem cell transplantation.

Abstract
PURPOSE This phase II multi-institutional trial was designed to assess response and toxicity of 2-chlorodeoxyadenosine (2-CDA) in patients with previously untreated follicular lymphoma. The clinical significance of detecting cells carrying the t(14;18) translocation (bcl-2/JH rearrangement) in peripheral blood and bone marrow by polymerase chain reaction (PCR) before, during and after treatment was also examined. PATIENTS AND METHODS Between May 1993 and October 1995, 37 patients were accrued: male/female: 15/22, median age 51 years (range: 20-78), stage III/IV: 9/28. Patients received a total 2-CDA dose of 0.7 mg/kg as continuous s.c. or i.v. infusions over 7 days, every 28 days for a maximum of 5 cycles. A total of 165 cycles were administered. In 25 patients, blood and bone marrow before, during and after treatment were available for PCR analysis of the bcl-2/JH rearrangements. RESULTS All 37 patients were evaluable for response and toxicity. The overall response rate was 84% (95% confidence interval, 68%-94%) with 14% CR (n = 5) and 70% PR (n = 26) and a median time to treatment failure of 15.7 months. bcl-2/JH rearrangement in peripheral blood and/or bone marrow was found in 10/25 of patients (40%) before treatment and 5 of these became repeatedly negative after 2-CDA therapy. There was no apparent association between bcl-2/ JH result and response. In 11 patients, 2-CDA was stopped because of progressive disease (n = 4), myelotoxicity (grade 2-3, n = 4), and other causes (n = 3, pulmonary embolism, metabolic disorder, and patient's decision). Four patients (11%) suffered from infections (grade 2-3). In 6 patients, persistent thrombocytopenia of 7.5 months (range: 3-21) occurred after completion of the 5 cycles. CONCLUSION 2-CDA is active in untreated follicular lymphomas, but time to treatment failure suggests no advantage compared with standard treatment and toxicity on haematopoietic stem cells appears to be more pronounced. Molecular remission is induced in a considerable proportion of patients with disappearance of the bcl-2/JH rearrangement, and its possible significance as a predictive factor for quality of response and relapse warrants further study.

Abstract
BACKGROUND: The incidence of non-Hodgkin's lymphoma in the elderly continues to increase. There has been a tendency among some treating physicians to minimize appropriate workup and treatment, which may product a negative effect on outcomes. METHODS: Several characteristics of non-Hodgkin's lymphoma in the elderly are reviewed, including classification and staging, pathophysiology, clinical presentation, and treatment strategies. RESULTS: The Working Formulation remains the principal classification used. In order and younger individuals, the prevalence of histologic subtypes and the stage at presentation are similar. Regardless of the regimen chosen, doxorubicin or mitoxantrone should be included if optimal responses are to be obtained. New purine analogs extend the therapeutic armamentarium. CONCLUSIONS: Advanced age and comorbidities can impair the capability for treatments to control non-Hodgkin's lymphoma. To enhance results, more studies that focus on the elderly are needed on drug combinations and the new purine analogs.

Abstract
The anticancer drug 2-chloro-2'-deoxyadenosine (CdA) belongs to the family of purine nucleoside analogs. CdA is exquisitely cytotoxic both to the dividing and to the non-dividing lymphocyte, which supports its use in lymphoproliferative disorders of low-grade malignancy. Indeed, the best clinical results with CdA are achieved in hairy-cell leukemia, in chronic lymphocytic leukemia, in Waldenström's macroglobulinemia and in low-grade malignant lymphoma. Most patients with hairy-cell leukemia achieve a complete response with a single course of CdA. However, the disease is not eradicated and a fraction of complete responders will eventually relapse. In chronic lymphocytic leukemia and in malignant lymphoma, complete or partial responses can be achieved in approximately 40% of previously treated patients, even after classical chemotherapy has failed. However, few responses sustain beyond 1 to 2 years, while longer unmaintained responses may be obtained in Waldenström's macroglobulinemia. More responses (70-80%) are achieved in patients with chronic lymphoproliferative disorders treated de novo with CdA but their impact on survival remains to be established. More than 10 years after its first use in clinical practice, late adverse consequences of the severe and sustained immunosuppression induced by CdA have not been reported but should still be closely monitored.

Abstract
Infection is a common adverse event after therapy with nucleoside analogs, including 2-chlorodeoxyadenosine (CdA). However, the incidence of CdA-related infections has been poorly documented. In this study we compare, in the same patient population, the incidence of infectious episodes during the 6-month period before CdA to their incidence during the 6 months after initiating therapy. Ninety-five patients with hematological malignancies were studied. The incidence of infectious episodes almost doubled after CdA (0.87 vs. 0.47 during the pre-CdA period). The following factors were associated with an increased risk of infection after therapy: a history of previous chemotherapy, infection during the pre-CdA period and a diagnosis of chronic lymphocytic leukemia or of non-Hodgkin's lymphoma. Age, neutrophil and lymphocyte count at onset of CdA and time interval between diagnosis and therapy with CdA did not correlate with the infectious risk. The pattern of infections was modified after therapy with an increase of herpes virus infections ( 1 vs. 8 episodes, p=0.04) and of fever of unknown origin (6 vs. 17 episodes, p=0.03). In conclusion, a population at high risk for developing infectious complications after CdA therapy can be identified. Specific measures aimed at reducing the incidence of infectious events should concentrate on this population.

Abstract
In an area of lymphoma classification still being defined, marginal-zone lymphomas have distinctive immunohistochemical and cytogenetic features that distinguish them from mantle-cell and follicular lymphomas. There are three subtypes: the extranodal mucosa-associated lymphoid tissue (MALT) lymphomas, the nodal monocytoid B-cell (MBCL) lymphomas, and the splenic marginal-zone lymphomas. The MALT lymphomas represent the neoplastic counterpart of the gut-associated lymphoid tissue, which extends from the jejunum to the rectum. They arise in sites usually containing no lymphoid tissue, such as the stomach, thyroid, and salivary gland. Gastric MALT lymphomas, the most common, are associated with Helicobacter pylori. The MBCL lymphomas closely resemble MALT lymphomas and unlike other non-Hodgkin's lymphomas are commonly composite. Therapy for these lymphomas may include radiation therapy or surgery when disease is of limited extent. However, gastrectomy for gastric MALT lymphomas is not in favor because of the efficacy of antibiotic regimens that can eliminate H. pylori infection. Splenectomy may be indicated for splenic lymphomas. Purine analogs are promising therapeutic agents because they are specific for lymphoid cells. Also, they may prove useful in indolent cancers such as these, because of their activity against dividing and resting cells. Purine analogs may be considered as second-line therapy after alkylating agents for these lymphomas.

Abstract
Low-grade follicular lymphomas, follicular small cleaved and follicular mixed, generally follow an indolent but progressive course. Although available therapies induce responses, continuous relapse occurs. In investigating potential therapeutic regimens, researchers have sought regimens that will result in a postchemotherapy survival plateau rather than a pattern of continuous relapse. The newer, purine analogs, 2'-deoxycoformycin, fludarabine, and 2-chlorodeoxyadenosine have shown activity in the low-grade B-cell lymphomas, especially with the follicular histologic subtype. Response rates in studies of previously untreated patients approach 100%. The newer purine analogs are emerging as an important treatment approach for indolent B-cell lymphomas, but the impact on survival remains to be assessed.

Abstract
Three analogues of the purine 2-deoxyadenosine are available for the treatment of low grade lymphoproliferative disorders: pentostatin, cladribine and fludarabine. They have some common features in their mode of action, but differ both in their detailed pharmacology and the extent to which they have activity against specific lymphoid malignancies. Studies defining the scope of these drugs as single agents are now being followed by plans to exploit their potential synergy with other agents and clinically to define useful combination therapies.

Abstract
Low-grade non-Hodgkin's lymphoma (NHL) presents a formidable treatment challenge to oncologists. This review evaluates the various methods of disease and patient management. The natural history of various subtypes of low-grade NHL and the classification according to the National Cancer Institute Working Formulation are discussed in this review. Additionally, the various therapies in use; radiotherapy alone and combined with chemotherapy, chemotherapy with single alkylating agents such as chlorambucil and combination therapies, autologous and allogenic bone marrow transplantation, and therapy with purine analogs, such as chlorodeoxyadenosine and fludarabine. Patient survival in various studies using these treatment modalities are discussed. Treatment options need to be combined with the use of prognostic models, such as the International Index for optimal care of this difficult-to-treat group of patients.

Abstract
Lymphoid neoplasia is a complex area comprising multiple diseases with varied pathology, treatment, and outcome. The non-Hodgkin's lymphomas are reviewed here. Non-Hodgkin's lymphomas, collectively, represent the sixth most common cancer in the United States as well as the sixth most common cause of cancer deaths. The overall incidence of non-Hodgkin's lymphoma has risen steadily over the past four decades. Although some of this is attributable to human immunodeficiency virus (HIV)-associated lymphoma, HIV-associated disease accounts for only a small part of the increase in lymphoma. As our knowledge of normal as well as neoplastic lymphoid development has expanded on the basis of histopathology as well as adjunct cellular and molecular techniques, multiple classifications have been proposed to take these into account. The clinical relevance to our understanding of non-Hodgkin's lymphoma is the concept that various lymphoid cancers are counterparts of stages of normal lymphoid development. Stages of lymphoid development in terms of cell surface markers and immunoglobulin gene rearrangements have been well characterized. These are particularly applicable to the early B-cell development, which is antigen-independent and occurs in the bone marrow. Diseases correlating with these stages are largely acute lymphocytic and lymphoblastic leukemia/lymphoma and high-grade lymphomas, such as Burkitt's lymphomas. Much has been learned recently about subsequent antigen-dependent B-cell development in secondary lymphoid organs to improve our understanding of the corresponding stages of B-cell neoplasia. Many of these stages correlate with more recently described entities such as mantle cell and marginal zone lymphomas. Histologic study remains crucial in determining the subtype of NHLs, whereas immunohistochemistry, surface phenotype, and molecular studies are useful in selected cases. Although some lymphoma classifications may be better in terms of understanding the lymphoma biology, the working formulation remains useful to guide clinical decision making. Lymphomas classified as low grade are considered incurable with standard therapy when diagnosed, as is usual, at advanced stages. Different subtypes may have different median survivals, but the goal has typically been palliation, whereas experimental approaches are clearly needed. Intermediate and high-grade lymphomas are potentially curable with aggressive combination chemotherapy. Recent evidence suggests that CHOP chemotherapy is as effective as more complex regimens. Still, 40% to 50% of patients are cured. Prognostic factor analysis has allowed separation of subgroups with much better survival in whom CHOP is adequate versus those with much poorer survival in whom experimental approaches are rational. Additional subtypes of lymphomas have been described and characterized since the working formulation was developed, including mucosa-associated lymphoid tissue tumors (MALT-oma), mantle zone lymphoma, anaplastic large cell lymphoma and AILD-like T-cell lymphoma. Approaches to these entities are still being optimized. Newer approaches, including high-dose therapy with stem cell support, biologic agents, and newer chemotherapeutic agents are discussed, as are special situations such as localized lymphoma of certain sites and lymphoma in immunosuppressed patients.

Abstract
Fludarabine (FLU) is a new antimetabolite chemotherapeutic agent with promising therapeutic activity in the lymphoproliferative disorders and in particular in low-grade non-Hodgkin's lymphoma (LG-NHL). In order to evaluate FLU in combination with other antineoplastic agents, we used a three-drug combination of FLU, mitoxantrone and prednisone (FMP) to treat 18 patients with recurrent LG-NHL. The FMP regimen was as follows: FLU, 25 mg/m2 i.v. on days 1 to 3; mitoxantrone, 10 mg/m2 i.v. on day 1; prednisone 40 mg i.v. on days 1 to 5. Of the 18 patients, 4 (22%) achieved complete response (CR), 9 (50%) partial response, and the remaining 5 showed no benefit from the treatment. The 4 CR patients are still in remission after 4, 6, 6, and 8 months, respectively. The median duration of overall survival of all patients was 9 months. The major toxic effects observed were neutropenia (50%) and infections and/or febrile episodes (17%); no fatalities due to drug side effects occurred. These results confirm the efficacy of the fludarabine-mitoxantrone combination-containing regimen in inducting a good remission rate with moderate side effects in recurrent LG-NHL.
