Interferon-α for TP53 Myeloid Malignancy Post Allo-HSCT

Leukemia-associated immunophenotyping (LAIPs) was performed by flow cytometry at +1 month and +2 month after HSCT. If MRD was negative on two consecutive flow cytometry assays, interferon-α prophylaxis was initiated on day +75 after transplantation, and cyclosporine was tapered on day +100 after transplantation. The dose of interferon-α was 3 million units/time, subcutaneously injected twice a week. Cycles were given every 4 weeks until hematologic relapse or up to 6 cycles.
