Post-HSCT maintenance therapy became standard practice in 2021, utilizing agents like venetoclax, decitabine, azacitidine, blinatumomab, DLI, and targeted therapies. Primary outcomes were overall survival (OS) and disease-free survival (DFS); secondary outcomes included relapse rate and treatment-related toxicities.</p><p><strong>Results: </strong>Among 94 patients (64 with ALL, 30 with AML), ALL patients receiving maintenance therapy had an OS of 78% versus 47% without maintenance (p=0.02); DFS was 64% with maintenance and 45% without (p=0.12).
