Popis: Abstract Background Extended first‐line therapy (1LT) has improved clinical outcomes in newly diagnosed multiple myeloma (NDMM). This retrospective study of NDMM patients evaluated the relationship between dose‐attenuation of 1LT and duration of therapy (DOT) and DOT on outcomes. Methods Adults with NDMM not undergoing stem cell transplant (SCT) from January 1, 2012 toMarch 31, 2018 from the Integrated Oncology Network were included; 300 were randomly selected for chart review. 1LT DOT, time to next treatment (TTNT), progression‐free survival (PFS), and overall survival (OS) were estimated using Kaplan–Meier analysis. Marginal structural models evaluated relationships between DOT and TTNT, PFS, and OS at 2 years accounting for confounders and survival bias from the time‐dependent nature of DOT. Results Of 300 chart‐reviewed patients, 93 were excluded for incomplete data or meeting exclusion criteria. Among 207 NDMM patients, median age was 74 years; 146 (70.5%) did not receive dose‐attenuation during 1LT. Patients with short DOT were older, frailer, with a higher comorbidity burden, and a significantly lower proportion had an Eastern Cooperative Oncology Group PS = 0. As DOT increased, more patients underwent dose‐attenuation (p
