The purpose of this study is to obtain bone marrow and peripheral blood samples, along with clinical data from patients with Multiple Myeloma (MM), Waldenstrom's Macroglobulinemia (WM), Smoldering MM, and other lymphoplasmacytic lymphomas (LPL) including but not limited to MGUS and IgG or IgA LPL. These samples will become part of a tissue bank and will be used in ongoing studies to find out more about the causes and biology of MM, WM and LPL; to identify what factors result in normal cells becoming cancer; to determine how to improve treatment options; to study how the immune system identifies abnormal cells; and to evaluate the immune function in these diseases. The investigators will also study the tumor cells at the level of the participant's genes to develop treatment strategies as well as to better understand how biologic differences affect patient outcomes.
