METHODS Patients with CBF AML who underwent HSCT in complete remission (first or second) from January 2007 through December 2018 were included in this analysis. RESULTS MRD by polymerase chain reaction at HSCT was assessed in 50 of 76 patients, and 44 (88%) had evidence of MRD (MRDpos). MRDpos patients had 3-year overall survival (OS) and leukemia-free survival (LFS) rates of 69.3% and 66.3%, respectively. Six MRD-negative patients had 3-year OS and LFS rates of 100% and 100%, respectively. Thirty-five of the 70 evaluable patients (50%) had a day +100 MRD assessment by RT-PCR, and 14 (40%) were MRDpos. The presence of MRD by RT-PCR on day +100 was not associated with lower estimates of LFS (75% vs 82.2%; P = .3) but was associated with a higher relapse incidence, although the difference did not reach statistical significance (27.6% vs 9.7%; P = .2). CONCLUSIONS Durable complete remissions can be achieved in patients with CBF AML with HSCT even if they are MRDpos by RT-PCR at HSCT. The clinical impact of frequent MRD monitoring for identifying a group at high risk for early relapse and then for determining the best time point for therapeutic interventions to prevent impending relapse warrants investigation in prospectively designed clinical trials. © 2020 American Cancer Society.BACKGROUND Approximately 60% to 80% of people with Parkinson's disease (PD) experience cognitive impairment that impacts on their quality of life. Cognitive decline is a core feature of the disease and can often present before
