Abstract BACKGROUND: Tumed sequential treatment with fludarabine/cyclophosphamide/rituximab (FC-R) followed by Y-90 ibritumomab tiuxetan (IT) radioimmunotherapy may improve progression-free survival in patients (pts) with CD20+ NHL. However, even unpretreated pts submitted to four to six cycles of a fludarabine-containing combination and then IT at an Y-90 activity of 15 MBq/kg will experience severe prolonged, transfusion-dependent and only partially reversible pancytopenia, thus limiting its use in a non-curative setting (Jurczak et al., ASH 2005). AIM: We report on a trial including anthracycline-pretreated pts with relapsing CD20+ lymphoma > age 50 and unsuitable for myeloablative tr…
