Abstract
The spectrum of plasma cell disorders is broad. Monoclonal gammopathy of undetermined significance and smoldering multiple myeloma are asymptomatic disorders characterized by monoclonal plasma cell proliferation in the bone marrow in the absence of end-organ damage. Waldenström macroglobulinemia typically involves an ontogenically less mature lymphoplasmacytic bone marrow cell and is characterized by secretion of a monoclonal IgM protein. Solitary plasmacytoma is the only known potentially curable plasma cell disorder. Finally, AL (immunoglobulin light chain) amyloidosis and POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome are disorders characterized by low tumor burden but profound multisystemic disease. Updated diagnostic criteria for these disorders, risk stratification models to determine prognosis, and the current management of these diverse entitles are discussed in this review.

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 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'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
BACKGROUND IFN alpha are cytokines used for a number of years in the treatment of certain hemopathies, i.e. of a myeloid and lymphoid etiology. IFN alpha are a family of polypeptides produced by eukaryote cells in response to various stimulant agents. The first trials using this cytokine in humans were carried out by H. Strander in the years 1965-1970. IFN alpha contain anti-viral, anti-proliferative and immunomodulatory properties. The access of clinicians to IFN alpha molecules, in addition to elements produced by genetic engineering for approximately the past 20 years, has permitted a number of therapeutic trials to be carried out. In hematology the clinical interest of IFN alpha was primarily in chronic myeloid and lymphoid proliferating syndromes. Certain indications have to date been well demonstrated. However, the impact of IFN alpha on therapeutic care of certain hemopathies as compared to conventional treatment remains controversial. At the same time, the frequency of side effects from treatment with IFN alpha and its cost should be taken into consideration. CURRENT POSITION AND MAJOR POINTS The therapeutic trials carried out over the past ten years have proven the interest of IFN alpha in, essentially, two diseases: on one hand chronic myeloid leukemia with the acquisition of cytogenetic remission and on the other malignant non-Hodgkin's follicular type lymphoma. However, as regards other hemopathies the place of IFN alpha remains debatable. PERSPECTIVES The future of IFN alpha use in the treatment of hemopathies appears to be linked to its association with new treatments, an association, however, where its efficacy and superiority should be demonstrated. This is the case in chronic myeloid leukemia where IFN alpha could be associated with aracytine or the inhibitors of tyrosine kinase. Also, in the treatment of malignant non-Hodgkin's lymphomas as well as the studies concerning the association between IFN alpha and monoclonal antibodies, in particular antibody anti-CD 20.

Abstract
Waldenström's macroglobulinemia is a rare malignant disorder of B lymphocytes. There are no studies on the use of interferon-alpha (IFN-alpha) as frontline therapy in this disease. Between April 1991 and September 2000, we treated 21 newly diagnosed patients using 8 mg/m(2) chlorambucil and 40 mg/m(2) prednisone p.o. daily for 10 days and 3 megaU/m(2) IFN-alpha three times a week. Patients who responded after induction continued receiving IFN until relapse or death. We found a high frequency of peripheral neuropathy (43%) and grade 3 diffuse marrow fibrosis (43%). Objective response was achieved in 12 (57%) patients, including 4 (19%) complete responders. Median time from treatment to response was 8 months (range 3-18). Median progression-free survival was 70 months (95% CI 47-93), and overall survival was 91 months (95% CI 50-132). Patients who achieved objective response lived longer (91 vs. 33 months, p < 0.03), as did patients who had lactic dehydrogenase (LDH) < 180 U/L (89 vs. 54 months, p < 0.01). Grade 3 hematologic toxicity was observed during induction in 5 patients. IFN-alpha is an effective agent for the induction and maintenance treatment of Waldenström's macroglobulinemia patients. LDH > 180 U/L and failure to respond are adverse prognostic factors.

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
A randomized phase II multicenter clinical trial comparing the efficacy of fludarabine (FAMP) to that of the association of cyclophosphamide, doxorubicin and prednisone (CAP) in 92 patients with Waldenstrom's macroglobulinemia in first relapse or with primarily resistant disease, was conducted on the behalf of the 'Groupe Coopératif Macroglobulinémie'. The main analysis of this study failed to demonstrate a clear cut benefit of FAMP in terms of overall survival (OS), although a significant benefit in terms of time to disease progression and event-free survival (EFS) was noted. In this rare disorder, where few randomized trials have been conducted, we took advantage of this trial to assess treatment differences while integrating quality of life considerations. We thus performed a quality-adjusted survival analysis, using the quality-adjusted time without symptoms or toxicity (Q-TWiST) approach. Four health states differing in terms of quality of life (QoL) were defined, namely treatment-related toxicity, treatment free of toxicity, no treatment or symptoms, and relapse. The average time spent in these health states (TOX, CT, TWiST and REL, respectively) were then weighted by utility coefficients reflecting relative QoL value according to that of TWiST and summed up giving the so-called Q-TWiST. No difference was found between randomized groups in terms of mean CT. Mean TOX in the two groups were similarly close except when considering alopecia as a relevant toxic event. By contrast, mean TWiST was 5.9 months longer in the FAMP group than in the CAP group (P = 0.006). Unsurprisingly, given the absence of difference in OS but the difference in EFS in favor of the FAMP group, mean REL was increased by 6.8 months in the CAP group (P = 0.047). As a result, benefit of FAMP in terms of average Q-TWiST only relied on the value of the utility coefficient attributed to REL (U(REL)), with a significant benefit when UREL ranged from 0 to 0.28, ie in patients undergoing poor QoL after relapse, which is likely.

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.

Abstract
Waldenström's macroglobulinemia is an unusual low-grade lymphoplasmacytic lymphoma characterized by the production of monoclonal IgM. The clinical manifestations associated with WM can be classified as those related to direct tumor infiltration, by the amount and specific properties of circulating IgM, and by the deposition of IgM in various tissues. Asymptomatic patients should be followed without treatment. The management of the disease relies on the administration of systemic chemotherapy to reduce tumor load and on the application of plasmapheresis to remove circulating IgM. Standard treatment consists of oral chlorambucil, which induces response in at least 50% of patients, resulting in a median survival of approximately 5 years. Nucleoside analogues (cladribine, fludarabine) are effective in most previously untreated patients. These agents are the treatment of choice for patients with disease resistant to alkylating agents. New treatment approaches include high-dose therapy with stem-cell support and administration of monoclonal anti-CD20 antibodies.
