BACKGROUND & OBJECTIVES Irradiation with 131I is used for the treatment of various thyroid disorders. It is likely that radioiodine while in systemic circulation may cause some adverse effects on antioxidative enzymes present in red blood cells (RBCs). Zinc, on the other hand, has been reported to maintain the integrity of cells under certain toxic conditions. The present study was conducted to...
Thyroid carcinoma is primarily treated by surgery combined with radioactive 131iodine (131I) treatment; however, certain patients exhibit resistance to 131I treatment. Previous research indicated that nuclear factor‑κB (NF‑κB) was associated with resistance to 131I in cancer cells. The present study aimed to investigate the effects of NF‑κB on 131I uptake and apoptosis in thyroid carcinoma cell...
OBJECTIVE The objective of this study, in addition to confirming that therapy with 131I causes oxidative stress, was to evaluate the effect of supplementation with vitamins C and E and selenium on this phenomenon by measuring plasma 8-epi-PGF2a, a marker of lipid peroxidation. SUBJECTS AND METHODS Forty patients with thyroid cancer submitted to thyroidectomy, who received 3.7 GBq 131I after l...
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...
We applaud Ghobrial and Witzig for their comprehensive and balanced article on "Radioimmunotherapy: A New Treatment Modality for B-cell NonHodgkin's Lymphoma." These authors have provided a review that will serve the oncologist and oncology patient well. They have not engaged in arcane and tedious discussion of which anti-CD20 monoclonal antibody (ibritumomab tiuxetan [Zevalin] or tositumomab/i...
With the success of targeted monoclonal antibody therapy in non-Hodgkin's lymphoma, attempts were made to further improve efficacy through the addition of a radioisotope. A goal of radioimmunotherapy is to utilize the monoclonal antibody to deliver radiation to a tumor bed with relatively limited toxicity to the surrounding normal tissues. I-131 Tositumomab is an iodine-131 labeled anti-CD20 mu...
This study measured the growth over time of experimental coronary artery (CA) thrombi by radiolabeled fibrinogen uptake. 125I-fibrinogen was injected into dogs and 24 hours later CA thrombi were induced by electrical current. Twenty-four hours after CA thrombus induction, 131I-albumin (group A) or 131I-fibrinogen (group B) was injected. At 48 hours after thrombi induction, the thrombi were remo...
BACKGROUND Thyroid dysfunction after exposure to low or moderate doses of radioactive iodine-131 (131I) at a young age is a public health concern. However, quantitative data are sparse concerning 131I-related risk of these common diseases. OBJECTIVE Our goal was to assess the prevalence of thyroid dysfunction in association with 131I exposure during childhood (≤ 18 years) due to fallout from ...
In vitro multicell spheroids from a human melanoma cell line and the human colon cancer cell line HT29, used as control, have been established as a model of poorly vascularized micrometastases in vivo. The antimelanoma monoclonal antibody 96.5 was radiolabeled with 131I at specific radioactivities from 1.85 to 3.96 GBq/mg. Cytotoxicity of 131I-96.5 to the spheroids, at an initial size of 300 mi...
