Abstract

Purpose: This study aimed to evaluate the efficacy and safety of the treatment with 90Y-ibritumomab tiuxetan following a short-course of rituximab with cyclophosphamide-adriamycin-vincristine-prednisone (R-CHOP) in high-risk elderly patients with previously untreated diffuse large B-cell lymphoma (DLBCL). Experimental Design: From December 2006 to October 2008, 55 high-risk elderly (age ≥60 years) untreated DLBCL patients were treated in seven Italian institutions with a short-course of chemotherapy consisting of four cycles of R-CHOP21 followed by 90Y-ibritumomab tiuxetan 6 to 10 weeks later. Results: Of the 55 patients, 48 underwent radioimmunotherapy. The overall response rate to the entire treatment regimen was 80%, including 73% complete remissions and 7% partial remissions. Eight (50%) of the 16 patients who achieved less than a complete response with CHOP improved their remission status after 90Y-ibritumomab tiuxetan administration. With a median follow-up of 18 months, the 2-year progression-free survival was estimated to be 85%, with a 2-year overall survival of 86%. 90Y-ibritumomab tiuxetan toxicity consisted of grade 3 to 4 hematologic toxicity in 28 of 48 patients, mainly neutropenia (23 patients) and thrombocytopenia (15 patients). Red cells and/or platelets transfusions were given to three patients. Conclusion: This study evaluated the feasibility, efficacy, and safety of a short-course R-CHOP21 regimen followed by 90Y-ibritumomab tiuxetan in high-risk elderly DLBCL patients.
