Smoldering multiple myeloma represents approximately 10% to 15% of all myeloma cases, but more thorough evaluation may decrease that number in the future. Risk stratification is important in this patient population to avoid overtreatment or undertreatment. Patients with low-risk disease can be observed without treatment, but those at higher-risk should be enrolled on clinical trials. If a clinical trial is not an option in these patients, a time-limited intervention with lenalidomide ± dexamethasone can be considered.

The presence of monoclonal proteins is common, with a prevalence in the United States around 5% that increases with age. Although most patients are asymptomatic, most cases are caused by a clonal plasma cell disorder. Monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM) are asymptomatic precursor conditions with variable risk of progression to multiple myeloma. In recent years, significant progress has been made to better understand the factors that lead to the development of symptoms and progression to myeloma. This review summarizes the current diagnosis treatment guidelines for MGUS and SMM and highlights recent advances that underscore a shifting paradigm in the evaluation and management of plasma cell precursor conditions.

Background: Obesity, and in particular severe obesity, is increasingly prevalent in the United States. Epidemiological studies have shown an association in multiple myeloma (MM) between obesity and mortality (Teras et al, Br J Haematol 2014). Autologous peripheral blood stem cell transplantation (autoPBSCT) remains a crucial aspect of treating MM, and the NCCN Guidelines recommend all eligible patients be evaluated for transplant. There is limited data analyzing the relationship between severe obesity and transplant outcomes in MM patients in the era of modern therapy, routine post-transplant maintenance, and genetic-based risk stratification. Methods: We retrospectively reviewed consecutive patients undergoing autoPBSCT for MM at our institution from 2010–2017. Patients were categorized by body mass index (BMI) and Revised International Staging System (R-ISS) score. Patients were followed from time of first transplant until death. Surviving patients and those lost to follow-up were censored at last point of contact. Cox proportional hazard regression models and associated log-rank tests were used to assess whether age, BMI, lag time between diagnosis and transplant, and R-ISS score were associated with risk of death. Post-transplant hospital length of stay (LOS) was evaluated using generalized linear models with response following a gamma distribution. Results: 314 patients (59.2% male) were included. BMI was categorized as nonobese ([16, 30) kg/m2; n=178, 56.7%), obese ([30, 35) kg/m2; n=72, 22.9%) or severely obese ([35, 55) kg/m2; n=64, 20.4%) and was not found to be associated with risk of death following transplant, either independently (P=.17) or when adjusting for age, sex, lag, and R-ISS (P=.26). As expected, R-ISS score was associated (P=.006) with risk of death after transplant. No association was found between mean LOS and BMI (P=.875). Kaplan-Meier mortality estimates are shown in . Conclusions: Obesity and severe obesity were not associated with an increased risk of mortality for MM patients receiving autoPBSCT. Although severe obesity is a health hazard, this should not be used to exclude patients from transplant.

Multiple myeloma (MM) is caused by the neoplastic proliferation of plasma cells. These neoplastic plasma cells proliferate and produce monoclonal immunoglobulin in the bone marrow causing skeletal damage, a hallmark of multiple myeloma. Other MM-related complications include hypercalcemia, renal insufficiency, anemia, and infections. The NCCN Multiple Myeloma Panel members have developed guidelines for the management of patients with various plasma cell dyscrasias, including solitary plasmacytoma, smoldering myeloma, multiple myeloma, systemic light chain amyloidosis, and Waldenström's macroglobulinemia. The recommendations specific to the diagnosis and treatment of patients with newly diagnosed MM are discussed in this article.

Multiple myeloma is a malignant neoplasm of plasma cells that accumulate in bone marrow, leading to bone destruction and marrow failure. This manuscript discusses the management of patients with solitary plasmacytoma, smoldering multiple myeloma, and newly diagnosed multiple myeloma.
