- Abstract
Allogeneic SCT is an effective therapy for lymphoma. Reduced-intensity conditioning (RIC) reduces non-relapse mortality (NRM) associated with myeloablative conditioning but relapse rates are high when performed in active disease. This study was designed to explore the safety and outcome of ibritumomab tiuxetan (Zevalin) combined with RIC in patients with advanced lymphoma. The study included 12 patients, median age 54 years (37–62), with a median of four prior treatments (2–6) and active disease documented on PET–CT. Zevalin 0.4 mCi/kg was given on day −14 and fludarabine combined with BU (n=6) or melphalan (n=6) was started on day −6. GVHD prevention was tapered 3 months after SCT to augment the graft-versus-lymphoma effect. All patients engrafted, a median of 14 days after SCT. Eighty-three percent achieved CR/PR. With a median follow-up of 21 months (12–37), 2-year PFS is 33%. Only three patients relapsed; cumulative incidence 25%. NRM was 42%, predominantly due to acute GVHD. Zevalin–RIC is feasible with consistent engraftment, acceptable organ toxicity, but high rates of acute GVHD. The low incidence of relapse suggests augmented anti-lymphoma effect. Zevalin–RIC merits further study. Better results may be achieved in patients earlier in disease course and with longer duration of immune-suppression.Bone Marrow Transplantation (2008) 41, 355–361; doi:10.1038/sj.bmt.1705919; published online 19 November 2007
