Aggressive salvage treatments to improve patient outcome have been unsatisfactory. Therefore, we evaluated the efficacy of yttrium-90-ibritumomab tiuxetan (ZevalinĀ®; 90Y-IT) consolidation after early salvage chemotherapy with autologous stem cell transplantation. Thirty-seven patients with intermediate-high risk DLBCL not in complete remission (CR) after three cycles of rituximab, cyclophosphomide, doxorubicin, vincristine and prednisone (R-CHOP) were assessed retrospectively. After early salvage treatment, 70% achieved CR and 30% partial remission. Twenty patients underwent additional consolidation with 90Y-IT. During the 3-year follow-up, 50% in the 90Y-IT-treated group experienced relapse compared to 82.3% in the other cohort (p=0.002). Progression- and disease-free survival were significantly longer in the 90Y-IT group. However, probably due to the relatively short follow-up period, no difference in overall survival was observed. 90Y-IT consolidation after early salvage chemotherapy improves treatment responses and reduces the percentage of relapses without significant additional toxicities.
