Reduced‐intensity conditioning with fludarabine/busulfan versus fludarabine/low‐dose melphalan in patients with non‐Hodgkin lymphoma undergoing allogeneic haematopoietic stem cell transplantation

Reduced-intensity conditioning regimens are commonly used in allogeneic haematopoietic cell transplantation for non-Hodgkin lymphoma (NHL); however, the optimal regimen remains unknown. In this study, the outcomes of adult patients with NHL who received fludarabine plus reduced-dose busulfan (6.4 mg/kg; Flu/Bu2) (n = 286) and fludarabine plus low-dose melphalan (80 or 100 mg/m
