Abstract

INTRODUCTIONRadioimmunotherapy (RIT), a novel agent developed by binding a radioisotope to a monoclonal antibody, is considered a treatment option for radiation‐sensitive tumors.1,2 Previous studies investigating the efficacy of RIT showed promising results for B‐cell non‐Hodgkin's lymphoma (NHL).3,4 Based on previous studies, 90Y‐ibritumomab tiuxetan (90Y‐ibritumomab tiuxetan; Zevalin; Biogen Idec Inc., San Diego, CA, USA and Schering AG, Berlin, Germany) is currently approved for the treatment of relapsed or refractory follicular lymphoma and consolidation after primary treatment.5 We performed a phase II study of single administration and repeated therapy with 131I‐rituximab as salvage therapy in patients with relapsed or refractory B‐cell NHL.6,7 We have confirmed the efficacy and safety of 131I‐rituximab in a previous study.Among the subtypes of NHL, follicular lymphoma and mantle cell lymphoma are sensitive to radiotherapy. Therefore, for patients with stages I–II follicular lymphoma, 24–30 Gy involved site radiation therapy (ISRT) is the recommended standard treatment.8 In contrast, rituximab‐containing combination therapy is regarded as the first treatment in patients with follicular lymphoma stages III or IV who do not respond well to local control therapy.8 RIT is approved for relapsed or refractory follicular lymphoma and consolidation after primary treatment; however, the long‐term follow‐up data are problematic in few cases.8,9
