Recently, a new preparative regimen for older patients with aggressive CD20-positive B-cell lymphoma utilizing standard-dose 0.4 mCi/kg 90Y ibritumomab tiuxetan combined with high-dose BEAM followed by ASCT showed a CR rate of 92% with a follow-up of 9 months. Finally, high-dose radioimmunotherapy with 90Y ibritumomab tiuxetan and high-dose cyclophosphamide/etoposide followed by ASCT for poor-risk or relapsed B-cell NHL have been reported, with a 2-year DFS of 80%. The use of conventional dose of Yttrium did not need heavy radioprotection procedures, and can be widely distributed in transplant centers.
