Popis: 376 Background: Older adults with acute myeloid leukemia (AML) have identified home time (HT) as a critical outcome influencing their treatment selection. However, few studies have characterized HT in this disease setting. Methods: We conducted a retrospective, observational study of adults age ≥60 diagnosed with AML from 2015 to 2020 at University of North Carolina Health. First-line therapy was classified by intensity: low (hypomethylating agent [HMA]), intermediate (HMA+Venetoclax), and high (anthracycline-based). The primary outcome was cumulative HT days from time of diagnosis. A day was defined as HT if an individual was not hospitalized and did not utilize emergency department services or ambulatory oncology clinics. Secondary outcomes were proportion of days at home (PDH) and overall survival (OS). Covariates included demographics and disease risk by ELN 2017 criteria. HT was evaluated via summary statistics with comparisons among treatment groups made via linear (for HT / PDH) or Cox proportional hazard (for OS) regression models adjusted for age & ELN risk. PDH was further adjusted for log of follow up time. Median OS was calculated via the Kaplan-Meier method. Results: 197 individuals were identified. Mean age was 71 (range 60-95), 79% were white, and 59% male. 38% received high-intensity therapy, 33% received low, and 29% intermediate. Mean age was lower in the high-intensity group (66 vs 74 in low, 75 in intermediate; Kruskal-Wallis p < 0.0001). Mean HT was 284 days, and median survival was 10.3 months (95% CI 8.4-12.7). Mean HT was greater in the high-intensity group at 409 days (CI 310-508) vs. 243 (158-328) in low and 169 (121-216) in the intermediate group (Table). The high-intensity group had greater median OS at 19.9 months vs. 8.8 (low) or 7.7 (intermediate) but a lower mean adjusted PDH (high: 0.60 vs. low: 0.73 vs. intermediate: 0.75; p < 0.0001). In adjusted models, these differences remained statistically significant. Mean HT, median OS, and mean adjusted PDH did not differ significantly between the low & intermediate groups. Conclusions: Older adults with AML spend a tremendous amount of time - roughly 40% of days - engaged in oncology care. Although receiving high-intensity therapy was associated with longer OS, increases in HT were more modest, indicating that much of the survival gains were spent engaged in care. Shared treatment decision-making should incorporate patient preferences for securing HT versus attempting to prolong survival.[Table: see text]
