Abstract
Waldenström Macroglobulinemia (WM) is a rare indolent lymphoma with heterogeneous clinical presentation. As there are no randomised trials suggesting the best treatment option in treatment-naive patients, guidelines suggest either rituximab-combining regimens or BTK-inhibitors (BTKi) as feasible alternatives. Several factors play in the decision-making process: patients’ age and fitness, disease characteristics and genotype. Chemoimmunotherapy (CIT) represents a fixed-duration, less expensive and effective option, able to achieve prolonged time-to-next treatment even in patients with unfavourable genotypes. Immunosuppression and treatment-related second cancers may represent serious concerns. Proteasome-inhibitor-based regimens are effective with rapid disease control, although bortezomib-related neuropathy discourages the choice of these agents and treatment schedules may not be easily manageable in the elderly. BTKi have demonstrated high rates of response and prolonged survival together with the convenience of an oral administration and limited cytopenias. However, outcomes are impacted by genotype and some concerns remain, in particular the continuous drug exposure that may result in extra-haematological complications and drug resistance. Although next-generation BTKi have improved treatment tolerance, the question whether BTKi should be offered as frontline therapy to every patient is still debated. Giving fixed-duration schedule, prolonged time-to-next treatment and outcomes independent of genotype, CIT is still our preferred choice in WM. However, BTKi remain a valuable option in frail patients unsuitable for CIT.

Abstract
Waldenström macroglobulinemia (WM) is an indolent low-grade non-Hodgkin lymphoma characterized by bone marrow infiltration by lymphoplasmacytic cells and associated clonal IgM paraproteinemia. Recent insights into the biology and genomic characteristics of WM have provided a further platform for more targeted therapies. Despite the high response rates and better depth and duration of responses, the disease remains incurable. This review focuses on use of the high-dose therapy with either autologous or allogeneic hematopoietic stem cell transplantation.

Abstract
Waldenstrom's macroglobulinemia (WM) is an indolent B-cell lymphoma, which is highly chemosensitive, with an overall response rate over 90% to novel agents. However, most patients eventually relapse after response to first-line chemotherapy, necessitating further treatment. The possibility of long-lasting remission after high-dose cytotoxic chemotherapy followed by stem cell rescue is high in WM due to the chemosensitive nature of the disease and lower proliferative activity compared to multiple myeloma. In this paper, we have reviewed current evidence on autologous (auto-) and allogeneic (allo-) stem cell transplantation (SCT) in WM. Auto-SCT can be safely performed in WM and is recommended as second-line treatment or beyond in eligible patients. It is associated with extremely low transplant-related mortality. Allo-SCT is effective in WM with incremental benefit due to graft-versus-WM effect, but is associated with high non-relapse mortality of 30%, hence should be preferably considered investigational as part of clinical trials in selected patients who have exhausted other treatment options.

Abstract
Waldenström macroglobulinemia (WM) is a rare, indolent, and monoclonal immunoglobulin M-associated lymphoplasmacytic disorder with unique clinicopathologic characteristics. Over the past decade, remarkable progress has occurred on both the diagnostic and therapeutic fronts in WM. A deeper understanding of the disease biology emanates from the seminal discoveries of myeloid differentiation primary response 88 (MYD88) L265P somatic mutation in the vast majority of cases and C-X-C chemokine receptor, type 4, mutations in about a third of patients. Although WM remains an incurable malignancy, and the indications to initiate treatment are largely unchanged, the therapeutic armamentarium continues to expand. Acknowledging the paucity of high-level evidence from large randomized controlled trials, herein, we evaluate the genomic aberrations and provide a strategic framework for the management in the frontline as well as the relapsed/refractory settings of symptomatic WM.

Abstract
Waldenström macroglobulinemia (WM) is a distinct hematologic malignancy characterized by a lymphoplasmacytic bone marrow infiltration and the presence of immunoglobulin (Ig)M monoclonal protein. Patients typically present at an advanced age, and a substantial proportion are asymptomatic at diagnosis. A unifying diagnosis of WM may be missed by an unsuspecting hematologist, as symptomatic patients present with a multitude of non-specific manifestations. Although constitutional and neuropathy-related symptoms predominate, concomitant IgM-induced hyperviscosity-associated features can provide useful diagnostic clues. There are specific indications for initiation of therapy. This review focuses on the most up-to-date management strategies of WM, in addition to highlighting the recent discoveries of MYD88 and CXCR4 mutations that have shed unprecedented light on the complex signaling pathways, and opened avenues for novel therapeutic targeting. Although WM remains incurable, with the rapid emergence and integration of effective novel therapies, its clinical course appears poised to improve in the foreseeable future.

Abstract
SUMMARY Over the last seven decades, Waldenström macroglobulinemia (WM) has changed from a clinical observation by an astute clinician to an uncommon, but well-defined clinical–pathologic entity. Similarly, therapeutic advances have evolved and now parallel our increasing understanding of the biology of WM. Very recently, the discovery of a highly prevalent somatic gene mutation has provided new understanding that challenges us to further individualize management of this disease. This article is intended to chronicle the 70-year development of our knowledge, treatment options and limitations that bring us to our current approach to WM, as well as the challenge for international collaboration in order to enable us to develop the most efficient path to optimal patient care.

Abstract
Waldenström's macroglobulinemia is a distinct disorder characterized by a monoclonal immunoglobulin M paraprotein and morphological evidence of lymphoplasmacytic lymphoma. It is relatively rare, accounting for approximately 2% of all hematological malignancies. The aim of treatment for patients with Waldenström's macroglobulinemia should be to improve the quality and duration of life with minimal side effects in the most cost-effective manner. It is not yet clear if achievement of a complete remission confers clinical benefit and it is possible that prolonging therapy to maximal response may increase toxicity without extra benefit. Plasma exchange is indicated for the acute management of patients with severe problems due to a circulating paraprotein. There are no comparative data but alkylating agent-based treatments, combination therapy or purine analogs are all suitable choices for the initial therapy of patients requiring treatment. In younger patients, in whom high-dose treatment is contemplated, there is a role for the use of rituximab; however, it should be administered with caution in patients with high levels of immunoglobulin M paraprotein or signs of hyperviscosity because of the risk of 'flare' in the paraprotein level and consequent adverse clinical events.

Abstract
Waldenström macroglobulinemia is a B-cell malignancy with lymphoplasmacytic infiltration in the bone marrow or lymphatic tissue and a monoclonal immunoglobulin M protein (IgM) in the serum. It is incurable with current therapy, and the decision to treat patients as well as the choice of treatment can be complex. Using a risk-adapted approach, we provide recommendations on timing and choice of therapy. Patients with smoldering or asymptomatic Waldenström macroglobulinemia and preserved hematologic function should be observed without therapy. Symptomatic patients with modest hematologic compromise, IgM-related neuropathy that requires therapy, or hemolytic anemia unresponsive to corticosteroids should receive standard doses of rituximab alone without maintenance therapy. Patients who have severe constitutional symptoms, profound hematologic compromise, symptomatic bulky disease, or hyperviscosity should be treated with the DRC (dexamethasone, rituximab, cyclophosphamide) regimen. Any patient with symptoms of hyperviscosity should first be treated with plasmapheresis. For patients who experience relapse after a response to initial therapy of more than 2 years' duration, the original therapy should be repeated. For patients who had an inadequate response to initial therapy or a response of less than 2 years' duration, an alternative agent or combination should be used. Autologous stem cell transplant should be considered in all eligible patients with relapsed disease.

Abstract
Waldenström macroglobulinemia (WM) is a B-cell disorder characterized primarily by bone marrow infiltration with lymphoplasmacytic cells (LPCs), along with demonstration of an IgM monoclonal gammopathy in the blood. WM remains incurable, with 5-6 yr median overall survival for patients with symptomatic WM. The main therapeutic options include alkylating agents, nucleoside analogues, and rituximab, either in monotherapy or in combination. Studies involving combination chemotherapy are ongoing, and preliminary results are encouraging. However, there are several limitations to these approaches. The complete response rate is low and the treatment free survival are short in many patients, no specific agent or regimen has been shown to be superior to another, and no treatment has been specifically approved for WM. As such, novel therapeutic agents are needed for the treatment of WM. In ongoing efforts, we and others have sought to exploit advances made in the understanding of the biology of WM so as to develop new targeted therapeutics for this malignancy. These efforts have led to the development of proteasome inhibitors, of them bortezomib, several Akt/mTor inhibitors, such as perifosine and Rad001, and immunomodulatory agents such as thalidomide and lenalidomide. Many agents and monoclonal antibodies are currently being tested in clinical trials and seem promising. This report provides an update of the current preclinical studies and clinical efforts for the development of novel agents in the treatment of WM.

Abstract
Lymphoplasmacytic lymphoma (LL) is incurable by standard therapy (median survival: 60 months). UK transplant registry data 1984-2003 identified 18 cases of histologically verified LL (median age: 50 years, range: 38-58 years). Nine patients received high dose chemotherapy [plus total body irradiation (TBI) in 1/9] and autologous peripheral blood stem cells (PBSC). Disease status at transplant was complete remission (2), partial remission (5), primary refractory (1) or relapse (1). Transplant related mortality (TRM) at 12 months was 0%. Median follow-up is 44 months with 4 year disease free survival 43% and overall survival 73%. Karnofsky performance status (KPS) is 80-100%. The nine allografted patients (median age: 49 years, range: 39-56 years) were conditioned with standard TBI (2), BEAM (2) or FLU-MEL (5) and received PBSC from HLA-matched sibling (8) or unrelated (1) donors. Disease status at transplant was partial remission (7) or primary refractory (2). TRM at 12 months was 44%. Complications included graft failure (2), grades I-II acute graft versus host disease (aGVHD) (2), grades III-IV aGVHD (3) and chronic GVHD (4). Median follow-up is 32 months with 4 year disease free survival 44% and overall survival 56%. KPS is 70-100%.

Abstract
Over time, Waldenström macroglobulinaemia (WM) has evolved conceptually from a clinical syndrome to a distinct clinicopathological entity. Progress is being made in standardization of the disease definition and treatment response criteria, although nosologic controversies persist. According to the Second International Workshop on WM, the disease is defined as a B-cell neoplasm characterized by a lymphoplasmacytic infiltrate in the bone marrow, with an associated immunoglobulin (Ig) M paraprotein. Disease symptoms are often divided into those related to tumour infiltration and those related to the rheological effects of the monoclonal IgM. As with other low-grade lymphomas, asymptomatic patients are observed only, with treatment reserved for symptomatic patients. There is no standard treatment for WM and choices include rituximab, alkylating agents, purine nucleoside analogues, alone or in combination, as well as autologous peripheral blood stem cell transplant in eligible patients. Novel treatments, such as bortezomib, oblimersen sodium, perifosine and others are being evaluated.

Abstract
PurposeAlkylating agents and the anti-CD20 monoclonal antibody rituximab are among appropriate choices for the primary treatment of symptomatic patients with Waldenström macroglobulinemia (WM), and they induce at least a partial response in 30% to 50% of patients. To improve these results, we designed a phase II study that included previously untreated symptomatic patients with WM who received a combination of dexamethasone, rituximab, and cyclophosphamide (DRC).Patients and MethodsSeventy-two patients were treated with dexamethasone 20 mg intravenously followed by rituximab 375 mg/m2intravenously on day 1 and cyclophosphamide 100 mg/m2orally bid on days 1 to 5 (total dose, 1,000 mg/m2). This regimen was repeated every 21 days for 6 months. Patients' median age was 69 years and many had features of advanced disease such as anemia (57%), hypoalbuminemia (40%), and elevated serum beta2-microglobulin (43%).ResultsOn an intent-to-treat basis, 83% of patients (95% CI, 73% to 91%) achieved a response, including 7% complete, 67% partial, and 9% minor responses. The median time to response was 4.1 months. The 2-year progression-free survival rate for all patients was 67%; for patients who responded to DRC, it was 80%. The 2-year disease-specific survival rate was 90%. Treatment with DRC was well tolerated, with 9% of patients experiencing grade 3 or 4 neutropenia and approximately 20% of patients experiencing some form of toxicity related to rituximab.ConclusionOur large, multicenter trial showed that the non–stem-cell toxic DRC regimen is an active, well-tolerated treatment for symptomatic patients with WM.

Abstract
The role of allogeneic stem cell transplantation (SCT) in Waldenstrom's macroglobulinaemia (WM) is not yet clear, as published data on allogeneic SCT in WM are limited. We present a retrospective study of allogeneic SCT in five patients with WM. Median age was 56 years (range 40-60 years). All patients were heavily pretreated. Conditioning therapy with busulphan and cyclophosphamide was used for all patients and all were given cyclosporine and methotrexate for graft-versus-host disease prophylaxis. With a median follow-up of 32 months (range 2-43), all except one are alive and disease free. Progressive, delayed decline in serum IgM levels were noted in all the patients, suggesting an active graft-versus-Waldenstrom's effect. With the limited available data, it appears that allogeneic SCT is a useful treatment option for advanced WM.

Abstract
Waldenstrom's macroglobulinemia is defined by bone marrow lymphoplasmacytic infiltration and by production of monoclonal IgM. Treatment is employed only to symptomatic patients. Alkylating agents (chlorambucil), nucleoside analogues and rituximab are reasonable choices for primary therapy. Combination therapy either with nucleoside analogues with alkylating agents and/or rituximab or rituximab with chemotherapy such as CHOP or cyclophosphamide are also reasonable frontline treatment options for WM patients. Several factors should be taken into account when choosing the most appropriate primary treatment. These factors include the age of the patient and possible co-morbidities, the presence of cytopenias and especially thrombocytopenia, the presence of symptoms and signs indicative of hyperviscosity, the need for rapid disease control due to severe symptoms, significant splenomegaly or lymphadenopathy, symptomatic peripheral neuropathy and whether the patient is candidate for autologous stem cell transplantation. For patients with refractory or relapsing disease, the use of an alternate first-line agent is reasonable. Outside the setting of a clinical trial, the administration of high-dose therapy should be reserved only for patients refractory to alkylating agents, purine nucleoside and rituximab. For patients who develop resistance to all three classes of agents, alemtuzumab, thalidomide with or without dexamethasone or bortezomib could be tried.

Abstract
Purine analogues have been shown to be active in a variety of B- and T-cell malignancies. Among them, pentostatin is also a tight binding inhibitor of adenosine deaminase (ADA), a key enzyme of purine metabolism. ADA is present in all human tissues, with the highest levels in the lymphoid system. Early clinical trials with pentostatin used high doses for acute lymphoblastic leukemias, which were characterized by high levels of ADA. Through the efforts of a few investigators, low-dose regimens that are active and well tolerated for indolent lymphoid malignancies have been developed. Myelosuppressive adverse effects have been shown to be minimal using these schedules. Lymphoplasmacytic lymphoma (LL) is an indolent chronic B-cell lymphoproliferative disorder moderately responsive to alkylating agents. All of the purine analogues have shown activity in LL. However, the advantage of pentostatin over the other agents is the relatively specific toxicity to lymphoid cells and the paucity of myelosuppression as a single agent. No direct comparisons of the agents have been investigated, although pentostatin may be considered to be preferred since it has not been associated with toxicity to myeloid progenitors in colony assays. This is of significance for patients who might benefit from high-dose chemotherapy with autologous stem cell transplantation.

Abstract
The diagnosis of Waldenström's macroglobulinemia (WM) requires evidence of bone-marrow infiltration by lymphoplasmacytoid lymphoma and detection of serum monoclonal protein of IgM type. The normal counterpart of the WM malignant cell is believed to be a postgerminal-center B cell. The clinical manifestations and laboratory abnormalities associated with WM are related to direct tumor infiltration and to the amount and specific properties of IgM. Asymptomatic patients should be followed without treatment. When treatment is indicated, the three main choices for systemic frontline treatment are chlorambucil, the nucleoside analogues fludarabine or cladribine and the monoclonal antibody rituximab. There is evidence that high-dose therapy with autologous stem-cell transplantation is effective even in patients with advanced and resistant disease. Patient's age, hemoglobin and serum beta2-microglobulin before treatment are important prognostic variables which correlate with survival.

Abstract
PURPOSE To review the diagnostic criteria, prognostic factors, response criteria, and treatment options of patients with Waldenstrom's macroglobulinemia (WM). METHODS A review of published reports was facilitated by the use of a MEDLINE computer search and by manual search of the Index Medicus. RESULTS WM should be regarded as a distinct clinicopathologic entity and confined to those patients with lymphoplasmacytoid lymphoma who have demonstrable serum immunoglobulin M monoclonal protein. Treatment decisions should rely on specific clinical and laboratory criteria. Initiation of therapy should not be based on serum monoclonal protein levels per se. The three main choices for systemic primary treatment of symptomatic patients with WM include alkylating agents (chlorambucil), nucleoside analogs (fludarabine and cladribine), and the monoclonal antibody rituximab. There are no data from prospective randomized studies to recommend the use of one first-line agent over another, although consideration of a patient's candidacy for autologous stem-cell transplantation (ASCT) should be taken into account to avoid stem cell-damaging agents. There are preliminary data to suggest that combinations of nucleoside analogs and alkylating agents with or without rituximab may improve response rates at the expense of higher toxicity. CONCLUSION WM is a distinct low-grade lymphoproliferative disorder. When therapy is indicated, alkylating agents, nucleoside analogs, and rituximab are reasonable choices. Several factors, including the presence of cytopenias, need for rapid disease control, candidacy for ASCT, age, and comorbidities, should be taken into consideration when choosing the most appropriate primary treatment.

Abstract
Waldenstrom's macroglobulinemia (WM) is a rare chronic B-cell lymphoproliferative disorder characterized by macroglobulin (immunoglobulin M; IgM) paraproteinemia. The clinical manifestations associated with WM can be related to those of direct organ tumor infiltration, hyperviscosity and tissue deposition of IgM. Treatment must be individualized according to the nature of the clinical manifestations. Plasmapheresis has a role in patients whose symptoms are caused by increased serum viscosity. Chlorambucil was first used with response rates varying between 31% and 72% and is now probably the most commonly used oral agent. Melphalan and cyclophosphamide may have similar clinical efficacy. The addition of corticosteroids does not seem to increase response rates and the use of combination chemotherapy in the first-line setting is not recommended. Fludarabine and cladribine are cross-resistant and induce a response in 30%-60% of patients who have had prior therapy with alkylating agents and as many as 100% of previously untreated patients. Thirty-five percent to 50% of patients respond to single rituximab therapy, with limited toxicity. There are no data from prospective randomized studies to guide the choice between alkylating agents, nucleoside analogues, and rituximab for first-line therapy of WM. Autologous and allogeneic stem cell transplantation may be considered for patients with primary refractory/relapsing disease, especially in the younger age groups. Thalidomide alone or in combination with steroids/clarithromycin may be a useful salvage regimen for some heavily pretreated patients with cytopenia, even though toxicity is considerable. Splenectomy is rarely indicated.

Abstract
Waldenström macroglobulinemia (WM) is a low-grade lymphoproliferative disorder characterized by the presence of an immunoglobulin M monoclonal protein in the blood and monoclonal small lymphocytes and lymphoplasmacytoid cells in the marrow. The disease is uncommon and there is a lack of clear diagnostic criteria. WM is treatable but not curable and long-term survival is possible. Therefore, the treating physician needs to carefully balance the risks and benefits of treatment. Treatments are aimed at relieving symptoms resulting from marrow infiltration and the hyperviscosity syndrome. Therapies available for initiation of treatment include alkylating agents, purine nucleoside analogs, and rituximab. Chlorambucil has been the mainstay of treatment for many years and remains useful, especially in older patients. Rituximab has become an important new therapy for this disease because of its positive treatment responses, acceptable toxicity, and lack of therapy-associated myelosuppression and myelodysplasia. Currently, rituximab is being combined with chemotherapy. Other options of treatment include interferon and corticosteroids. Emerging therapies include stem cell transplantation (autologous and allogeneic) for younger patients. Currently, there are few comparative data on which to state an absolute opinion concerning the best available treatment for patients with WM.

Abstract
This report concerns a patient with IgM AL amyloidosis due to a B cell lymphoproliferative disorder who was successfully treated with VAD and subsequent high-dose melphalan followed by autologous stem cell support. After this chemotherapeutic regimen, the patient showed complete hematological remission and improvement in nephrotic syndrome. These findings suggest that high-dose melphalan may also be effective for lymphoplasmacytoid cells producing monoclonal IgM which are phenotypically distinct from plasma cells. Myeloablative therapies, such as high-dose melphalan, should definitely be considered as a treatment option for AL amyloidosis, irrespective of the type of precursor immunoglobulin.

Abstract
Waldenstrom's macroglobulinemia is a rare form of indolent lymphoma characterized by the production of a monoclonal immunoglobulin M protein, and complications such as hyperviscosity, cytopenias and peripheral neuropathy. Conventional treatment approaches are based on alkylators or nucleoside analogs, but in the absence of a clearly superior regimen, a broad array of alternative therapies exists. Choices range from biological agents to combination chemotherapy to stem-cell transplantation. A rational approach therefore must be based on careful patient assessment and individualization of therapy.

Abstract
Waldenström macroglobulinemia (WM) is a lymphoid neoplasm characterised by a monoclonal lymphoplasmacytic expansion accompanied by a serum monoclonal immunoglobulin M (IgM). In some patients, the monoclonal protein will lead to a characteristic hyperviscosity syndrome. Although indolent, WM is incurable and most patients eventually succumb to disease progression. Thus, we need to better understand the natural history and biology of the disease. Recent work has shown that half of patients with WM harbour deletions in the long arm of chromosome 6. Increasing evidence suggests the disease is a defined pathological entity and not purely a clinical syndrome. Current therapeutic modalities include alkylator agents, purine nucleoside analogues, and rituximab. The optimum initial therapeutic strategy is not yet defined, and current clinical trials are addressing the role of combination therapy. In this review, we summarise the current understanding of the pathogenesis, clinical and laboratory features, prognostic factors, and therapeutic options for patients with WM. We also discuss current knowledge of WM and available therapies.

Abstract
Published data on transplantation in Waldenstrom's macroglobulinemia (WM) are still limited. We present a retrospective multicentric study of 27 WM patients who underwent 19 autologous (median age, 54 years) and 10 allogeneic (median age, 46 years) transplantations. Median time between diagnosis and transplantation was 36 months; 66% of patients had received three or more treatment lines and 72 % had chemosensitive disease. High-dose therapy (HDT) and autologous transplantation induced a 95% response rate (RR), including 10 major responses. With a median follow-up of 18 months, 12 patients are alive at 10 to 81 months and eight are free of disease progression at 10 to 34 months. The toxic mortality rate (TRM) was 6%. Allogeneic transplantation was preceded by HDT in nine patients and by a nonmyeloablative regimen in one patient. The RR was 80%, including seven major responses. With a median follow-up of 20.5 months, six patients are alive and free of progression at 3 to 76 months. Four patients died, all from toxicity, resulting in a TRM of 40%. HDT followed by autologous transplantation is feasible in WM, even in heavily pretreated patients, with some prolonged responses but a high relapse rate. Conversely, allogeneic transplantation is more toxic, but likely induces a graft-versus-WM effect and may, for some patients, result in long-term disease control.

Abstract
Twelve patients with Waldenstrom's macroglobulinemia (WM) underwent treatment with the nonmyelosuppressive combination regimen BLT-D: clarithomycin (Biaxin [BXN], Abbott Laboratories, Abbott Park, IL) 500 mg orally twice daily, low-dose thalidomide (THAL) 50 mg orally escalated to 200 mg daily, and dexamethasone (DXM) 40 mg orally once weekly all with modification for toxicity. Omeprazole (correction of omepraxole) 20 mgm orally twice daily for 2 days with the DXM, and enteric-coated aspirin 81 mg orally daily were also administered. Twelve patients have been evaluated. All had previously received at least one purine analogue or alkylating agent. Five had a reduction in either leukocytes and/or platelets prior to treatment, of which three were disease-related. Median age was 62 years. All patients received a minimum of 6 weeks of therapy. Of the 12 patients, 10 had a significant response (83%) consisting of three near complete, three major, four partial, and two minor responses. Four of five had restoration of reduced blood counts. Two with minor responses did not receive sufficient dose escalation due to toxicity. Median time on therapy was 7 months (range, 3 to 28 months). Patients were removed from therapy primarily due to neurotoxicity. Drug resistance occurred in three patients, with one transformation to large cell lymphoma. Toxicity was as follows: gastrointestinal (primarily constipation), 42%; neurological, 100%; endocrine, 42%, and thrombotic, 8%. Most toxicities were World Health Organization (WHO) grade 1 or 2; however, neurological toxicity was more prominent and severe in WM patients than in myeloma. BLT-D is effective in WM. Because of its toxicity, predominantly neurological, BLT-D may best serve as an induction regimen or to "rescue" patients with refractory disease or disease-related low counts.

Abstract
This presentation represents consensus recommendations for the treatment of patients with Waldenstrom's macroglobulinemia (WM), which were prepared in conjunction with the second International Workshop held in Athens, Greece during September 2002. The faculty adopted the following statements for the management of patients with Waldenstrom's macroglobulinemia: (1) Alkylating agents, nucleoside analogues, and rituximab are reasonable choices for first line therapy of WM. (2) Both cladribine and fludarabine are reasonable choices for the therapy of WM. (3) Combinations of alkylating agents, nucleoside analogues, or rituximab should at this time be encouraged in the context of a clinical trial. (4) In WM, rituximab can cause a sudden rise in serum IgM and viscosity levels in certain patients, which may lead to complications, therefore close monitoring of these parameters and symptoms of hyperviscosity is recommended for WM patients undergoing rituximab therapy. (5) For relapsed disease, it is reasonable to use an alternate first line agent or re-use of the same agent; however, since autologous stem cell transplantation may have a role in treating patients with relapsed disease it is recommended that for patients in whom autologous transplantation is seriously being considered, exposure to alkylator or nucleoside analogue drugs should be limited. (6) Combination chemotherapy for patients who can tolerate myelotoxic therapy, thalidomide alone or with dexamethasone, can reasonably be considered to have relapsed. (7) Autologous stem cell transplantation may be considered for patients with refractory or relapsing disease. (8) Allogeneic transplantation should only be undertaken in the context of a clinical trial. (9) Plasmapheresis should be considered as interim therapy until definitive therapy can be initiated. (10) Rituximab should be considered for patients with IgM-related neuropathies. (11) Corticosteroids may be useful in the treatment of symptomatic mixed cryoglobulinemia. (12) Splenectomy is rarely indicated but has been used to manage painful splenomegaly and hypersplenism.

Abstract
Despite effectiveness of standard chemotherapy regimens, complete responses are infrequent in Waldenstrom's macroglobulinemia (WM) and there are no cures. Since WM shares certain biological and clinical features with myeloma, including responsiveness to alkylating agents, evaluation of high-dose therapy (HDT) with transplant, which is effective in myeloma, is an obvious next step in an effort to achieve high response rates and improve survival. Due to the indolent nature of the disease and older patients with comorbidities, such evaluations have been infrequent in the past. We have evaluated the safety and efficacy of high-dose melphalan with peripheral blood stem cell (PBSC) support in eight patients between the ages of 45 and 69 years with WM. Adequate numbers of stem cells were collected in six patients; however, two patients with more extensive prior fludarabine therapy failed to collect adequate cells and required a second attempt at stem cell collection. Seven patients were treated with melphalan 200 mg/m(2), including two patients who received tandem transplants; one patient received melphalan 140 mg/m(2) with total body irradiation (TBI). There was no treatment-related mortality and toxicities were manageable. Recovery of bone marrow after transplant was prompt except in one patient with extensive prior use of fludarabine. All the eight patients achieved at least partial response (PR), including one complete response (CR). Five patients are alive and with out relapse (77+ to 6+ months post-transplant). Other investigators have reported similar experience suggesting safety and efficacy of HDT in WM. However, therapy with purine analogues leads to stem cell damage with decreased ability to collect adequate numbers of stem cells. This suggests that the PBSCs should preferably be procured prior to extensive use of purine analogues. Future strategies in WM will include a plan to evaluate the role of HDT along with biological agents, role of purging using rituximab, post-HDT maintenance strategies (including immunotherapy), and evaluation of nonmyeloablative regimens containing fludarabine to achieve higher response rates and improve survival.

Abstract
Waldenstrom's macroglobulinemia (WM) is a chronic lymphoproliferative disorder characterized by lymphoplasmacytic infiltrate and a monoclonal IgM serum peak. Treatment includes cytotoxic chemotherapy with alkylators, or purine nucleoside analogues and monoclonal anti-CD20 antibody. The role of stem cell transplantation (SCT) in WM has not been established. We identified 24 published cases of WM treated with high-dose chemotherapy (HDC) followed by autologous SCT (ASCT). The median age was 50 years; half of the patients had refractory disease and received a variety of preparative regimens. Nine complete and 14 partial responses were observed, with one early death. Fifteen patients were alive and well at follow-ups ranging from 1 to 132 months. Six additional patients, with a median age of 45 years (range, 30 to 62), who received allogeneic SCT have been reported. All were heavily pretreated with refractory or relapsed disease. Median time from diagnosis to transplant was 3.1 years (range, 1.3 to 7). Two patients died of complications of the procedure while one died of disease progression. Three patients were alive and well between 5 and 112 months post-transplant. The small number of reported patients precludes any significant conclusion except that SCT is feasible in WM and long-term disease control can be achieved in selected patients with autologous or allogeneic SCT, even in those with refractory disease.

Abstract
Waldenström's macroglobulinaemia is a rare B-cell malignancy. It is prevalent in the sixth and seventh decades, the median age at diagnosis being 63 years. Conventional treatment has involved alkylator therapy, especially chlorambucil given daily at a low dose or intermittently at a higher dose. Purine analogues, used initially as salvage therapy in refractory disease, are increasingly used for initial therapy. However, purine analogue therapy entails significant complications, including immunosuppression, pancytopenia and autoimmune haemolysis. Moreover, it is unclear whether purine analogues extend survival. All of these need to be considered before initiation of therapy. More recently, anti-CD20 monoclonal antibody and thalidomide have been used with a 30% response in treated patients. High-dose therapy with stem cell support achieves a partial response in a majority of patients receiving this modality of therapy. The median survival of 5 years has not improved considerably since the introduction of purine analogues. Complete response is still uncommon; using all available modalities of therapy may increase the complete response rate and improve survival. Great strides in understanding the malignant cell, the microenvironment and the potential interactions have identified potential targets for therapy in multiple myeloma. These agents may also be useful in Waldenström's macroglobulinaemia. Since this is a rare malignancy, all patients should be treated with well-designed clinical protocols to achieve improvement in outcome.

Abstract
Waldenström's macroglobulinaemia (WM) is most usefully defined as a distinct chronic lymphoproliferative disorder with characteristic marrow morphology and phenotype; although nodal morphology if available will reveal a lymphoplasmacytoid lymphoma, the presence of a significant IgM paraprotein defines the clinical features of the disease. The clonal cell is a B-cell expressing IgM, CD19, and CD20 but not IgD, CD5, CD10 or CD23 and has somatic hypermutation of immunoglobulin heavy chain variable regions consistent with a post-germinal centre origin. Treatment of WM has been dependent on alkylating agents with or without coriticosteroids for many years, supplemented by the use of therapeutic plasmapheresis in the initial stages for patients at risk from the clinical consequences of hyperviscosity. This approach to treatment results in response rates of approximately 60% with a median survival of about 60 months. There is increasing evidence to show that the purine analogues fludarabine and cladribine which are active in the treatment of patients who are resistant to alkylating agents such as chlorambucil may be able to achieve higher response rates when used as initial therapy. A prospective trial is being undertaken to compare fludarabine and chlorambucil as initial treatment; because of the effect of subsequent active treatment on patients who do not respond to the first treatment choice, the long-term outcome may be similar for both groups. Recent advances in therapy include the use of therapeutic monoclonal antibodies such as rituximab and the use of autologous or allogeneic transplant procedures for selected patients.

Abstract
Waldenstrom's macroglobulinemia is a lymphoplasmacytic disorder characterized by a monoclonal IgM protein, anemia, hepatosplenomegaly, and hyperviscosity. With the increasing use of screening chemistry evaluations, many patients are diagnosed without symptoms and are candidates for observation with no therapeutic intervention until symptoms develop. Plasma exchange can be useful to manage hyperviscosity but does not address the infiltrative process in the bone marrow, which requires cytoreductive therapy. This review covers current regimens that have been used to manage Waldenstrom's macroglobulinemia, including alkylating agents, purine nucleoside analogs, and rituximab. The value of steroids, radiotherapy, stem cell transplantation, and splenectomy is also reviewed. The lack of phase III studies does not permit an algorithm that would be appropriate for all patients. Treatment needs to be individualized based on patient age, the clinical manifestations of Waldenström's, and the patient's potential for developing toxic side effects of the selected treatment regimen.

Abstract
Waldenstrom's macroglobulinemia (WM) is a low-grade lymphoplasmacytoid malignancy of unknown etiology. It primarily affects elderly patients and is characterized by a monoclonal IgM component, varying degrees of cytopenias, lymphadenopathy and manifestations related to hyperviscosity syndromes. WM is usually treated with single agent nucleoside analogues or alkylating agents that often provide high response rates and durable remissions. Recurrence of the disease after primary therapy is not uncommon, and resistance to both alkylating agents and nucleoside analogs eventually emerges. Small numbers of patients have undergone high-dose chemotherapy (HDC) with either autologous (n = 24) or allogeneic (n = 6) stem cell transplantation (SCT) as treatment for this disease. Most patients in both groups achieved remission. Results are promising and a more in-depth analysis of possible applications of this treatment modality is attempted with this mini-review.

Abstract
Few reports are available on the treatment of patients with Waldenström macroglobulinemia (WM) and primary or secondary resistance to alkylating-agent-based regimens. From December 1993 through December 1997, 92 patients with WM resistant to first-line therapy (42) or with first relapse (50) after alkylating-agent therapy were randomly assigned to receive fludarabine (25 mg/m(2) of body-surface area on days 1-5) or cyclophosphamide, doxorubicin (Adriamycin), and prednisone (CAP; 750 mg/m(2) cyclophosphamide and 25 mg/m(2) doxorubicin on day 1 and 40 mg/m(2) prednisone on days 1-5). The first end point evaluated was the response rate after 6 treatment courses. Forty-five patients received CAP and 45 received fludarabine. Two patients died before the first course of chemotherapy. No statistical differences were observed between the 2 treatment arms with respect to hematologic toxicity or infections. Mucositis and alopecia occurred significantly more often in patients treated with CAP. Partial responses were obtained in 14 patients (30%) treated with fludarabine and 5 patients (11%) treated with CAP (P =.019). Responses were more durable in patients treated with fludarabine (19 months versus 3 months), and the event-free survival rate was significantly higher in this group (P <.01). Forty-four patients died, 22 in the fludarabine group and 22 in the CAP group. There was no statistical difference in the median overall survival time in the 2 study arms. Fludarabine was thus more active than CAP in salvage therapy of WM and should be tested as first-line therapy in a randomized comparison with alkylating agents.

Abstract
We report a 62-year-old male who underwent non-myeloablative allogeneic peripheral blood stem cell transplantation (PBSCT) because of his life-threatening severe pancytopenia due to refractory Waldenström's macroglobulinemia. This therapy was performed safely and he made a marked recovery from his cytopenia that had not been improved with any other therapy. Bone marrow aspirates showed post-transplant mixed chimerism during engraftment, and became completely donor-derived after a series of GVHD symptoms, without subsequent donor lymphocyte infusion. Our results suggest that non-myeloablative allogeneic PBSCT could be a good alternative for patients suffering from multi-drug resistant Waldenström's macroglobulinemia.

Abstract
PURPOSE We performed a prospective phase II study to assess the activity of thalidomide in patients with Waldenstrom's macroglobulinemia (WM). PATIENTS AND METHODS Twenty patients with WM were treated with thalidomide at a starting dose of 200 mg daily with dose escalation in 200-mg increments every 14 days as tolerated to a maximum of 600 mg. All patients were symptomatic, their median age was 74 years, and 10 patients were previously untreated. RESULTS On an intent-to-treat basis, five (25%) of 20 patients achieved a partial response after treatment. Responses occurred in three of 10 previously untreated and in two of 10 pretreated patients. None of the patients treated during refractory relapse or with disease duration exceeding 2 years responded to thalidomide. Time to response was short, ranging between 0.8 months to 2.8 months. Adverse effects were common but reversible and consisted primarily of constipation, somnolence, fatigue, and mood changes. The daily dose of thalidomide was escalated to 600 mg in only five patients (25%), and in seven patients (35%), this agent was discontinued within 2 months because of intolerance. CONCLUSION Our data indicate that thalidomide has activity in WM but only low doses were tolerated in this elderly patient population. Confirmatory studies as well as studies that will combine thalidomide with chemotherapy or with rituximab may be relevant.

Abstract
Current information on Waldenström macroglobulinemia (WM) is based on retrospective or single-institution studies of patients requiring therapy. Between 1992 and 1998, 231 patients with WM were enrolled in a prospective observational multicenter clinical trial. Of these, 182 patients with symptomatic or progressive disease were treated with 4 to 8 cycles of therapy with a purine nucleoside analogue, fludarabine (FAMP; 30 mg/m(2) of body-surface area daily for 5 days every 28 days). A serum beta2-microglobulin (beta2M) level below 3 mg/L and a hemoglobin level of at least 120 g/L (12 g/dL) at presentation predicted a lower likelihood of requiring therapy. The overall rate of response to FAMP therapy was 36% (95% confidence interval, 29%-44%), with 2% complete remissions. Patients who were 70 years old or older had a substantially lower likelihood of response (odds ratio, 0.34; P =.004) than younger patients. On multivariate analysis, a serum beta2M level of 3 mg/L or higher, hemoglobin level below 120 g/L, and serum IgM level below 40 g/L [4 g/dL] were significant adverse prognostic factors for survival. We developed a simple staging system for WM by using these variables and identified 4 distinct subsets of patients with estimated 5-year overall survival rates of 87%, 64%, 53%, and 22%, and 5-year progression-free survival rates of 83%, 55%, 33%, and 12%. Prognosis in WM is highly variable and serum beta2M was the dominant predictor of a need for therapy and of survival. FAMP has activity against WM. Our staging system may provide guidance for a risk-based approach to the treatment of WM.

Abstract
Preliminary evidence suggests that high-dose chemotherapy followed by autologous or allogeneic stem cell transplantation may be effective in some patients with resistant Waldenstrom's macroglobulinemia. During the last 10 years, seven patients with Waldenstrom's macroglobulinemia have received transplants at the MD Anderson Cancer Center, four with autologous and three with allogeneic stem cells. Four patients achieved partial remission, and three patients have remained alive for at least 2 years. Our data confirm the feasibility of high-dose therapy in patients with macroglobulinemia and support the need for prospective studies of this modality in patients with chemosensitive disease.

Abstract
Waldenström's macroglobulinemia (WM) is a clinical syndrome with diverse prognoses, and not all patients require therapy at diagnosis. Serum beta2 microglobulin is a major prognostic determinant, and asymptomatic patients with low beta2 microglobulin levels and preserved hemoglobin can be observed over long periods without therapy. Low-dose alkylating agents and purine analogs are commonly employed as initial therapy but rarely yield complete remissions. Patients who are refractory to or have relapse after alkylator or purine analogue therapy can be salvaged with purine analogs. Improvement in outcome demands a comprehensive approach aimed at increasing and sustaining complete remissions. Such an approach should probably employ Rituxan (IDEX Pharmaceuticals, La Jolla, CA) in conjunction with induction therapy, peripheral stem cell procurement before purine analog therapy, and high-dose therapy followed by maintenance therapy with interferon.

Abstract
PURPOSE To review the clinical features, complications, and treatment of Waldenström's macroglobulinemia, a low-grade lymphoproliferative disorder that produces monoclonal immunoglobulin (Ig) M. METHODS A review of published reports was facilitated by the use of a MEDLINE computer search and by manual search of the Index Medicus. RESULTS The clinical manifestations associated with Waldenström's macroglobulinemia can be classified according to those related to direct tumor infiltration, to the amount and specific properties of circulating IgM, and to the deposition of IgM in various tissues. Asymptomatic patients should be followed without treatment. For symptomatic patients, standard treatment consists primarily of oral chlorambucil; nucleoside analogs, such as fludarabine and cladribine, are effective in one third of previously treated patients and in up to 80% of previously untreated patients. Preliminary evidence suggests that anti-CD20 monoclonal antibody may be active in about 30% of previously treated patients and that high-dose therapy with autologous stem-cell rescue is effective in most patients, including some with resistance to nucleoside analogs. CONCLUSION Waldenström's macroglobulinemia has a wide clinical spectrum that practicing physicians need to recognize early to reach the correct diagnosis. When therapy is indicated, oral chlorambucil is the standard primary treatment, but cladribine or fludarabine can be used when a rapid cytoreduction is desirable. Prospective randomized trials are required to elucidate the impact of nucleoside analogs on patients' survival. A nucleoside analog is the treatment of choice for patients who have been previously treated with an alkylating agent.
