BACKGROUND/AIMS Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, and it has a poor prognosis and few therapeutic options. Radiotherapy is one of the most effective forms of cancer treatment, and P53 protein is one of the key molecules determining how a cell responds to radiotherapy. The aim of this study was to determine the therapeutic efficacy of iodine-131 in three...
Iodine-131 is a radioisotope that is routinely used for the treatment of differentiated thyroid cancer after total or near-total thyroidectomy. However, there is some evidence that iodine-131 can induce liver injury . Here we report a rare case of drug-induced liver injury (DILI) caused by iodine-131 in a patient with regional lymph node metastasis after total thyroidectomy. A 47-year-old woman...
RADIOACTIVE iodine (iodine-131) has been used extensively during the past 30 years for the treatment of hyperthyroidism and has been shown to control this disorder in the majority of cases in which it has been used. There have been varying reports of the incidence of post-radiation hypothyroidism which has been reported to be as high as 70 per cent in patients followed up for 10 years (Beling a...
Monitoring of air and milk samples is done routinely around nuclear facilities that release iodine-131 to the environment. Results from these measurements are used to calculate dose rates to the thyroids of people who live near such facilities. These calculated dose rates have large uncertainty factors associated with them due to the complexity of predicting the movement of iodine-131 through t...
To evaluate the effects of simple compensated fixed-dose iodine-131 therapy for thyrotoxicosis, the long-term results for 74 patients treated with a fixed dose of iodine-131 ranging from 5 to 12 mCi (185 to 444 MBq) were evaluated in the first 2 years of a trial. The dose selected was loosely based on the gross size of the thyroid gland. Routine antithyroid drug therapy was given for a minimum ...
In research institute for nuclear medicine (Tehran University of Medical Sciences) 50 patients with follicular thyroid carcinoma were evaluted retrospectively. The purpose of the study was assesment of the response of iodine-131 therapy. The best result were achieved when the patient treated with iodine-131 for the first time, in the 4th decade of life, with total thyroidectomy and no met...
self-instructional publications designed to increase the primary care provider’s knowledge of hazardous substances in the environment and to aid in the evaluation of potentially exposed patients. This course is also available on the ATSDR Web site, www.atsdr.cdc. gov/HEC/CSEM/. See page 3 for more information about continuing medical education credits, continuing nursing education units, contin...
Significant differences in findings were seen between the intake amounts of iodine-131 that were derived from direct measurements and the estimated intake from environmental monitoring data at the Fukushima accident. To clarify these discrepancies, we have investigated the iodine-131 and tellurium-132 body burdens of five human subjects, who after being exposed to a radioactive plume, underwent...
sodium iodide-131 is administrated for treatment of hyperthyroidism and thyroid cancer. iodine-131 has multiple routs of excretion (urine, saliva, sweat, milk, feces, exhalation) from the body. patients receiving sodium iodide-131 therapy exposes other persons and the environment to unwanted radiation and contamination. the major source of radiation dose from administration of iodine-131 is ext...
