Abstract Background We investigatedthe association between time-averaged area under the curve (AAUC) of cytomegalovirus (CMV) viral load (VL) by day 100 and overall survival (OS) at 1-year after hematopoietic cell transplantation (HCT). Methods In a retrospective cohort study, including patients receiving HCT between June 2010 and December 2017 from Memorial Sloan Kettering Cancer Center, AAUC was calculated for patients with detected VL. Patients were categorized into non-controllers (Q4) and controllers (Q1–Q3) using the highest AAUC quartile as cutoff. Cox models were used to estimate the association between AAUC and OS. Patients with non-detected CMV VL were categorized into elite-controllers (recipient+ [R+] or R−/donor+ [D+]) and R−/D−. Results The study (N = 952) included 282 controllers, 93 non-controllers, 275 elite-controllers, and 302 R−/D−. OS was 80.1% and 58.1% for controllers and non-controllers, respectively. In multivariable models, non-controllers had worse OS versus controllers (adjusted hazard ratio [HR] = 2.65; 95% confidence interval [CI], 1.71–4.12). In landmark analyses, controllers had similar OS as elite-controllers (HR = 1.26; 95% CI, .83–1.91) or R−/D− (HR = 0.98; 95% CI, .64–1.5). Conclusions Non-controllers had worse OS 1-year post-HCT. Controllers had similar OS as elite-controllers or R−/D−. Future studies are needed to validate our AAUC cutoff across different cohorts and CMV management strategies.
