GOAL The aim of this pilot study was to investigate the changes of circulating epithelial cells in the blood of patients with differentiated thyroid cancer after radioiodine-therapy with I-131. METHODS The cells were detected by fluorescence-microscopy via the epithelial-cell-adhesion-molecule (EpCAM), a molecule described to be over-expressed in most carcinoma tissues and also present on cir...

introduction: radioiodine therapy is an effective method for treating thyroid cancer carcinoma, but it has some affects on normal tissues, hence dosimetry of vital organs are important to weigh the risks and benefits of this method. the aim of this study is to measure the absorbed doses of important organs by mcnp (monte carlo n particle) simulation and comparing the results of different method...

introduction: there is a limited number of case reports published in the past decade confirming the radio-iodine presence in the tear. these observations as well as reported cases of salivary and lacrimal gland dysfunction after radioiodine therapy stimulated investigators to clarify whether lacrimal gland function can be affected post-radioiodine therapy. hence we planned a historical cohort s...

Ziel/Aim Restoration of iodine incorporation (redifferentiation) was achieved in previously radioiodine-refractory, unresectable thyroid carcinoma by mitogen-activated protein kinase (MAPK) inhibition. However, redifferentiation unsatisfactory BRAFV600E mutated (BRAF-MUT) thus far. Here we assess safety and efficacy therapy through genotype-guided MAPK-modulation patients with BRAF-MUT or wild ...

introduction: hyperthyroidism is a relatively common disorder caused by different etiologies. graves’ disease, and toxic-nodular goiter (plummer’s disease) are among the most common causes. treatment with radioiodine is considered to be the treatment of choice in many of the patients. higher biological half-life of ¹³¹i in hyperthyroid patients as compared with patients with differentiated thyr...

OBJECTIVE: To evaluate the changes in clinical parameters and in the approach to patients submitted to radioiodine therapy for Graves’ disease. MATERIALS AND METHODS: Dossiers of 226 patients submitted to radioiodine therapy for Graves’ disease in the period between January 1990 and December 2001 were retrospectively evaluated. For the purposes of statistical analysis, the 12-year period was su...

OBJECTIVE To evaluate the effects of pretreatment with the retinoid X receptor (RXR) agonist bexarotene on the efficacy of radioiodine therapy for metastases of differentiated thyroid carcinoma (DTC) with limited uptake of radioiodine (I-131). DESIGN An open prospective intervention study. METHODS Eight patients with metastases of DTC, with insufficient uptake of I-131 who showed increased ...

context: to evaluate treatment success and hypothyroidism following main methods of radioiodine therapy of toxic nodular goiter (tng); calculated versus fixed dose and high versus low dose of radioiodine. evidence acquisitions: we searched medline and scopus databases from inception till july 2013, for clinical trials that compared two different methods of radioiodine administration in tng. the...

OBJECTIVE To assess the predictability of outcome and evaluate the factors that may lead to treatment failure in patients with Graves' disease who are treated with a single dose of radioiodine. MATERIALS AND METHODS This is a retrospective study of 123 patients (M: 42; F: 81) with Graves' disease who received radioiodine therapy with a single fixed (10 mCi) dose for hyperthyroidism. Pretreatm...

background: induction of radioadaptive responses in cells pretreated with a low dose radiation before exposure to a high dose is well documented by many investigators. the aim of this study is to determine the frequency of chromosomal aberration in peripheral blood lymphocytes of patients treated by radioiodine (131i) for hyperthyroidism, with or without previous thyroid scan with 99mtc. materi...
