The objective of this study was to propose a model for predicting whether a patient would require dose adjustment. Methods This retrospective observational study included patients treated with lenalidomide and dexamethasone from June 2014 to September 2018 at a tertiary hospital. Demographic variables, patient functional status, disease, analytical data specific to myeloma, and treatment-related variables were collected. Univariate and machine learning (logistic regression and classification and regression trees model) analyses were also performed. Kaplan–Meier analysis was used to determine the time of toxicity onset. Only lenalidomide (and not dexamethasone) related dose reductions are included. Results A total of 64 patients received lenalidomide-dexamethasone. 69% (44) required dose reduction or discontinuation of treatment due to len...
