This article provides information on the diagnosis and management of smouldering myeloma, a precursor condition to multiple myeloma. It discusses various diagnostic tests and imaging techniques used to identify smouldering myeloma and emphasizes the importance of restaging if there is evidence of progression. The article also provides recommendations for screening and initial investigations for suspected myeloma. Additionally, it discusses risk stratification models and treatment options for smouldering myeloma, including the use of lenalidomide. The article concludes by highlighting ongoing clinical trials and the need for further research in the treatment of smouldering myeloma. [Extracted from the article]

Summary: The presence of a serum monoclonal component has been associated with poor outcomes in some lymphomas. However, data in follicular lymphoma (FL) are scarce. We studied 311 FL patients diagnosed at a single institution, for whom information on serum immunofixation electrophoresis (sIFE) at diagnosis was available. Baseline characteristics and outcomes were compared between patients with a positive (+sIFE) and a negative sIFE (−sIFE). sIFE was positive in 82 patients (26%). Baseline features were comparable between both groups, except for an older age and higher proportion of elevated β2‐microglobulin levels in the +sIFE group. With a median follow‐up of 4.6 years, a +sIFE was associated with a higher risk of early relapse (POD24, 27% vs. 15%, P = 0·02), shorter progression‐free survival (PFS; 42% vs. 52% at 5 years, P = 0·008), and shorter overall survival (OS; 59% vs. 77% at 10 years, P = 0·046). In patients >60 years, a +sIFE was an independent predictor of OS [hazard ratio (HR) = 2·4, 95% confidence interval (CI): 1·2–5·0; P = 0·02]. Approximately one quarter of patients with FL has a +sIFE at diagnosis, which is a predictor of poor outcome. These findings encourage further investigation of its relationship with B‐cell biology and the tumour microenvironment. [ABSTRACT FROM AUTHOR]

Summary: Skeletal survey (SS) continues to be used in the community to detect bone disease in patients with multiple myeloma (MM). While the false‐negative rate is high, the specificity of SS is less well characterised. Here, we compare the diagnostic accuracy of SS compared to 18F‐FDG‐PET/CT (positron emission tomography/computed tomography) in 79 patients referred to our tertiary centre with a diagnosis of smouldering MM. SS had a specificity of 83·1% (95% confidence interval: 72·0–90·5%). This study reinforces the importance of using more specific imaging techniques to avoid inaccurate diagnosis that could lead to the risks associated with unnecessary therapy in patients with smouldering MM.
