Prognosis is a prediction of the probable course of a condition or disease.
There is no definitely known cause of WM. As is the case with most cancers, there are probably multiple risk factors involved – some may be inherited predisposing genetic factors and some may be due to environmental or occupational exposures during one’s lifetime.
Waldenstrom’s macroglobulinemia (WM) is a lymphoma, or cancer of the lymphatic system. It is sometimes referred to as a lymphoplasmacytic lymphoma (LPL) with an associated monoclonal IgM paraprotein. The disease occurs in a type of white blood cell called a B-lymphocyte or B-cell, which normally matures into a plasma cell whose job is to manufacture immunoglobulins (antibodies) to help the body fight infection.
The bone marrow biopsy (BMB) is the definitive test for confirming the diagnosis of WM.
This procedure can be performed in a physician’s office or in a monitored setting (such as a hospital) under local anesthetic or light sedation. The specimen is usually obtained from the posterior iliac crest (back of the hip bone) by using a large-bore needle, although in some cases it may be taken from the sternum (breast bone) or other bones.
Both a liquid bone marrow sample (bone marrow aspiration) and a solid bone sample (bone marrow biopsy) may be taken during the procedure.
One of the primary means of assessing a WM patient’s disease status is periodic blood tests. Among the more common test sets are the Comprehensive Metabolic Panel (CMP), Complete Blood Count (CBC), and Immunoglobulins.
Each of the sets serves a specific purpose, as detailed below. There are several items in each set; explanations of each item, along with their typical reference ranges of normal values are provided in further detail in PDF format.
Below are some useful common terms that you may find in lab reports, hear your oncologist use, or read in medical articles about Waldenstrom’s macroglobulinemia.
Terms are also available in the glossaries of the IWMF booklets entitled Basic Immunology and Questions and Answers, which are located on this website in IWMF Publications.
A diagnosis of WM can be a daunting experience, especially when trying to fully understand new medical terminology and acronyms. Below is a guide to some commonly asked questions about WM and how best to manage your disease, organized into five key categories.
