MIRD dose estimate report No. 20: radiation absorbed-dose estimates for 111In- and 90Y-ibritumomab tiuxetan.
UNLABELLED Absorbed-dose calculations provide a scientific basis for evaluating the biologic effects associated with administered radiopharmaceuticals. In cancer therapy, radiation dosimetry supports treatment planning, dose-response analyses, predictions of therapy effectiveness, and completeness of patient medical records. In this study, we evaluated the organ radiation absorbed doses from in...
متن کاملAccurate dose calibrator activity measurement of 90Y-ibritumomab tiuxetan.
UNLABELLED This investigation examined the accuracy of dose calibrator activity measurement of the beta-emitting radiopharmaceutical (90)Y-ibritumomab tiuxetan. METHODS Five different facilities independently measured (90)Y in a 10-mL syringe geometry with 30 dose calibrator models from 3 different manufacturers. The activities ranged from 81.4 MBq (2.2 mCi) to 1,406 MBq (38 mCi) over the vol...
متن کاملQuantification of dose nonuniformities by voxel-based dosimetry in patients receiving 90Y-ibritumomab-tiuxetan.
UNLABELLED Abstract Objective: To assess the impact of nonuniform dose distribution within lesions and tumor-involved organs of patients receiving Zevalin(®), and to discuss possible implications of equivalent uniform biological effective doses (EU-BED) on treatment efficacy and toxicity. MATLAB™ -based software for voxel-based dosimetry was adopted for this purpose. METHODS Eleven lesions fr...
متن کاملDetection of 90Y extravasation by bremsstrahlung imaging for patients undergoing 90Y-ibritumomab tiuxetan therapy.
UNLABELLED Extravasation of therapeutic (90)Y-ibritumomab tiuxetan can cause significant injury. Detection of extravasated (90)Y using a γ-camera for patients undergoing (90)Y-ibritumomab tiuxetan therapy is a challenge because of the inherently low efficiency of bremsstrahlung imaging and the interference of prompt and scattered photons from (111)In that are still present in the body at the ti...
متن کاملRelapsed follicular lymphoma sequentially treated with rituximab and 90Y-ibritumomab tiuxetan. Case report.
BACKGROUND Monoclonal antibodies have dramatically changed the treatment possibilities for follicular lymphoma. (90)Y-ibritumomab tiuxetan (Zevalin) is the first radioimmunotherapy agent approved for the treatment of relapsed and resistant follicular lymphoma patients. Long-term benefit was observed especially for patients achieving CR after radioimmunotherapy. METHODS AND RESULTS A 65-year-o...
