Background: Waldenström's macroglobulinaemia
addressed in clinical research and guidelines to improve (WM) is defined as a lymphoplasmacytic lymphoma care for WM patients in the Netherlands.
primarily located in the bone marrow, accompanied by an immunoglobulin M (IgM) monoclonal protein in the serum. The symptoms are highly variable, which K e y W o r d s
can sometimes lead to a diagnostic delay. Currently, there is a wide range of therapeutic options used for the Waldenström's macroglobulinaemia, M-protein, immuno- management of WM but no approved therapeutic agents are available specifically for this disease.
Methods: An online survey was prepared and sent out to haematologists and haemato-oncologists in the Netherlands, together with an invitational letter to participate. Information was gathered about the preferred Waldenström's macroglobulinaemia (WM) is a methods of diagnosing and treating patients with WM in non-Hodgkin's lymphoma, characterised by infiltration general, and about the last WM patient diagnosed in their of the bone marrow with small lymphocytes, lymphoplasmacytic cells and plasma cells, accompanied Results: 83 (31.8%) responses were obtained, out of which by secretion of monoclonal immunoglobulin M (IgM) 68 (81.9%) contained responses to all three parts of the protein in the serum.1 WM is a rare disease, with an survey. The respondents most commonly used either overall incidence of approximately 3 per million people rituximab-CVP or chlorambucil as first-line treatment, per year and about 75-100 newly diagnosed patients in the whereas rituximab in combination with purine analogues Netherlands per year.

Most worked at an academic rituximab and corticosteroids. Many aspects must be taken hospital (38.6%) or at a HOVON level C (31.3%) hospital, into account when deciding on a certain treatment regimen which represents hospitals equipped to give intensive for a WM patient, which may be recognised as quite a treatment.

In the third part, physicians were asked about their last patient diagnosed with WM, the symptoms that led to the suspicion of WM, the therapeutic management of that patient and the time before a response was detected.

Since WM is considered a type of NHL, and treatment when a certain level of IgM or M-protein is effectiveness has been shown in one randomised trial, present, usually between 30g/l and 50 g/l.
