Eligibility Criteria

• * Patients with either monoclonal gammopathy of unknown significance age \>= 18 years old.
• * Both criteria must be met:
• * Serum monoclonal protein \< 3 g/dL or urinary monoclonal protein \< 500 mg per 24 hours and clonal bone marrow plasma cells \< 10%

• * OR Patients with smoldering multiple myeloma age \>= 18 years old.
• * Both criteria must be met:
• * Serum monoclonal protein \>= 3 g/dL or urinary monoclonal protein \>= 500 mg per 24 hours and/or clonal bone marrow plasma cells 10-60%
• * Absence of myeloma defining events or amyloidosis
• * Patients must be enrolled in clinical trials for SMM or MGUS at MD Anderson Cancer Center, including protocols PA15-0575 (NCT02726750) (Prospective observational study of clinical and genomic predictors of progression to myeloma in asymptomatic monoclonal gammopathies); 2015-0148 (Phase II single arm trial of Isatuximab in patients with intermediate and high risk smoldering multiple myeloma); and 2015-0371 (NCT02603887) (Pilot single arm, single center, open label trial of Pembrolizumab in patients with intermediate and high risk smoldering multiple myeloma) and any future clinical trials for MGUS and/or SMM that open at MD Anderson Cancer Center.
• * Only patients who are English or Spanish speaking are eligible.

• * Clonal bone marrow plasma cell percentage \>= 60%
• * Involved: uninvolved serum free light chain ratio \>= 100 measured by Freelite assay (The Binding Site Group, Birmingham, United Kingdom \[UK\])
• * \>1 focal lesions on magnetic resonance imaging (MRI) studies, if the patient has an MRI done per eligibility criteria (each focal lesion must be 5 mm or more in size)
