Differentiated thyroid carcinomas usually show good uptake and response to I-131 ablative treatment. In this study, 90 patients following near total thyroidectomy who were referred to our institute for I-131 therapy are retrospectively studied. The patients are divided in two groups. Group 1 revealed complete ablation after one dose of I-131. Group 2 needed more than one dose of I-131 for...
131-radioiodine has been widely used as an effective radionuclide for treatment of patients with thyroid diseases. The purpose of this study was to investigate the genotoxic effects of iodine-131 in human cultured lymphocytes. Whole blood samples from human volunteers were incubated with iodine-131 (10, 50, 100 µCi/1.5ml) for 2 h. The lymphocytes were mitogenically stimulated to allow for evalu...
Radioimmunotherapy is an established treatment modality in Non-Hodgkin's lymphoma. The only two commercially available radioimmunotherapies - (90)Y-ibritumomab tiuxetan is expensive and (131)I-tositumomab has been discontinued from commercial production. In resource limited environment, self-labelling (131)I-rituximab might be the only viable practical option. We reported our pioneer experience...
I-131 uptake in the breast has been described with a variety of normal and pathologic conditions. We present the case of a 38-year-old female who received 317 millicuries of radioactive I-131 treatment for papillary thyroid carcinoma. Post-treatment scan demonstrated I-131 uptake in an area of fat necrosis in the breast.
PURPOSE to compare lesion detectability of I-123 MIBG scintigraphy with that of high-dose I-131 MIBG and to evaluate incremental benefit of SPECT/CT over planar image for the detection and localization of the lesions in patients with I-131 MIBG therapy for malignant pheochromocytoma/paraganglioma and neuroblastoma. MATERIALS AND METHODS we retrospectively investigated 16 patients with maligna...
UNLABELLED The prevention of tumor recurrence after curative treatment of hepatocellular carcinoma (HCC) is unresolved. Postoperative intraarterial injection of (131)I-labeled lipiodol has been proposed as adjuvant treatment. The aim of this prospective randomized trial was to evaluate if a single dose of postoperative adjuvant intraarterial (131)I-lipiodol (vs. unlabeled lipiodol) could reduce...
PURPOSE The expression of extra domain B (ED-B) fibronectin is always associated with angiogenic processes and can be exclusively observed in tissues undergoing growth and/or extensive remodeling. Due to this selective expression, ED-B fibronectin is an interesting target for radioimmunotherapy of malignant diseases. The aim of this study was to identify the most appropriate ED-B-targeting radi...
Reactions between purified plasminogen and streptokinase, labelled with (131)I and (125)I respectively, were investigated by polyacrylamide-gel discontinuous electrophoresis. A molecular complex consisting of both (131)I-labelled plasminogen and (125)I-labelled streptokinase migrated between plasminogen and streptokinase. This complex contained bovine plasminogen activator activity. The relativ...
Targeted radioimmunotherapy in non-Hodgkin's B-cell lymphoma (NHL) offers an efficacious therapy and minimal toxicity compared to conventional chemotherapy. Iodine 131 tositumomab ((131)I-TST) is a murine monoclonal antibody against the CD20 cell surface protein and is directly covalently conjugated to (131)I, a radioactive beta and gamma emitter. While initially approved for use in relapsed, r...
