131I–Tositumomab in lymphoma
Radioimmunoconjugates are radioisotope-bound monoclonal antibodies that target radiation specifically to sites of lymphoma involvement. Initial studies of (131)I-tositumomab in non-Hodgkin lymphoma (NHL) have suggested benefit in patients with relapsed or refractory indolent disease. However, the routine adoption of this agent is tempered by concerns about associated toxicities and unclear long...
متن کاملPredicting hematologic toxicity in patients undergoing radioimmunotherapy with 90Y-ibritumomab tiuxetan or 131I-tositumomab.
UNLABELLED This study aimed at identifying clinical factors for predicting hematologic toxicity after radioimmunotherapy with (90)Y-ibritumomab tiuxetan or (131)I-tositumomab in clinical practice. METHODS Hematologic data were available from 14 non-Hodgkin lymphoma patients treated with (90)Y-ibritumomab tiuxetan and 18 who received (131)I-tositumomab. The percentage baseline at nadir and 4 w...
متن کاملUpdate on hybrid conjugate-view SPECT tumor dosimetry and response in 131I-tositumomab therapy of previously untreated lymphoma patients.
UNLABELLED A study of the use of (131)I-labeled tositumomab, preceded by an unlabeled tositumomab predose, for therapy of 76 previously untreated non-Hodgkin's lymphoma patients has been completed at the University of Michigan. Fifty-two of the 76 treated patients were imaged once during therapy with SPECT to assist in dosimetric estimation. In this article, the patient's average tumor dose, es...
متن کاملPatient-specific dosimetry for 131I thyroid cancer therapy using 124I PET and 3-dimensional-internal dosimetry (3D-ID) software.
UNLABELLED Compared with conventional, whole-organ, S-factor-based dosimetry, 3-dimensional (3D), patient-specific dosimetry better accounts for radionuclide distribution and anatomic patient variability. Its accuracy, however, is limited by the quality of the cumulated activity information that is provided as input. This input has typically been obtained from SPECT and planar imaging studies. ...
متن کاملRadioimmunotherapy with tositumomab and iodine-131 tositumomab for low-grade non-Hodgkin lymphoma: nursing implications.
PURPOSE/OBJECTIVES To review radioimmunotherapy approaches for low-grade non-Hodgkin lymphoma (NHL) with a focus on tositumomab and iodine-131 tositumomab (Bexxar, Corixa Corporation, Seattle, WA, and GlaxoSmithKline, Philadelphia, PA). Nursing implications for Bexxar therapy are reviewed, including radiation safety, patient education, and the management of therapy-related toxicities. DATA SO...
