Testis dosimetry in individual patients by combining a small-scale dosimetry model and pharmacokinetic modeling-application of (111)In-Ibritumomab Tiuxetan (Zevalin(®)).
A heterogeneous distribution of radionuclides emitting low-energy electrons in the testicles may result in a significant difference between an absorbed dose to the radiosensitive spermatogonia and the mean absorbed dose to the whole testis. This study focused on absorbed dose distribution in patients at a finer scale than normally available in clinical dosimetry, which was accomplished by combi...
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 کاملRadiation safety considerations with yttrium 90 ibritumomab tiuxetan (Zevalin).
Radioimmunotherapy is a recently approved treatment modality for non-Hodgkin's lymphoma that enables physicians to target cytotoxic localized radiation to tumor sites without using external-beam sources. Because it uses a pure beta emitter for therapy, (90)Y ibritumomab tiuxetan can be safely and routinely administered in an outpatient procedure, with few discharge instructions, and minimal ris...
متن کاملImaging and dosing in radioimmunotherapy with yttrium 90 ibritumomab tiuxetan (Zevalin).
Yttrium 90 ibritumomab tiuxetan consists of the murine monoclonal antibody ibritumomab securely bound to the second-generation chelator tiuxetan, which attaches the high-energy pure beta emitter (90)Y, for therapy, or the gamma emitter indium 111, for imaging. The biodistribution of the therapeutic dose of (90)Y ibritumomab tiuxetan can be predicted by using an imaging dose of the antibody labe...
متن کاملSafety and efficacy of radioimmunotherapy with yttrium 90 ibritumomab tiuxetan (Zevalin).
Patients with low-grade, follicular non-Hodgkin's lymphoma usually present with advanced disease, which is not considered curable with conventional therapies. New approaches are needed to improve the outcomes in patients with this disease. Yttrium 90 ibritumomab tiuxetan (Zevalin; Biogen Idec Inc, Cambridge, MA), is highly effective, with overall response rates of 73% to 83% and complete respon...
