Observational Prospective Research Study In Monoclonal Gammopathies leadINg to Myeloma

PRIMARY OBJECTIVE: I. To determine the rate of progression to multiple myeloma after 3 years of follow up. SECONDARY OBJECTIVES: I. To describe baseline patient characteristics and clinical variables. II. To identify molecular and genetic correlates that may predict for progression to multiple myeloma (MM). OUTLINE: Patients undergo collection of blood samples every 6 months for 3 years. Patients may also undergo a biopsy, x-rays, positron emission tomography (PET)/computed tomography (CT) scans, and/or magnetic resonance imaging (MRI) scans to check the status of disease at the discretion of the treating physician. After completion of 3 years on study, patients are followed up every 6-12 months thereafter.
