Radioiodine is regularly used in the treatment of thyroid cancer to eliminate residual malignant tissue after thyroidectomy and to treat metastasis. Because of the low dose of radioiodine used to treat thyroid cancer patients, leukemia is an uncommon complication of exposure to radioiodine. Here, we present a patient who developed therapy-related acute myeloid leukemia with inv(16)(p13.1q22);CB...

Complaints of a dry mouth (xerostomia) and sialoadenitis are frequent side effects of radioiodine treatment in differentiated thyroid cancer (DTC) patients. However, detailed prospective data on alterations in salivary gland functioning after radioiodine treatment (131I) are scarce. Therefore, the primary aim of this study was to prospectively assess the effect of high-activity radioiodine trea...

Various studies have demonstrated the safety and efficacy of recombinant human thyroid-stimulating hormone (rhTSH) for radioiodine remnant ablation. On this basis, rhTSH was approved in Europe for the radioiodine ablation of low-risk differentiated thyroid cancer (DTC) during thyroid hormone therapy with L-thyroxine (L-T4). Moreover, in December 2007, the US Federal Drug Administration approved...

OBJECTIVE To determine whether clinical and biochemical features of Graves' disease at presentation predict response to medical and radioiodine treatment. METHODS We carried out a retrospective 10-year study of 194 consecutive Saudi subjects with Graves' disease who were treated with antithyroid drugs, radioiodine therapy, or both, between January 1995 and December 2004 at King Khalid Univers...

UNLABELLED The long-term dental safety profile of high-dose radioiodine therapy remained elusive despite more than 6 decades of clinical use. METHODS In a cohort study, we investigated the incidence of sialadenitis, xerostomia, caries, and tooth extractions after high-dose radioiodine therapy for differentiated thyroid cancer and explored risk factors by multiple regression models. RESULTS ...

Radioiodine treatment-induced hypothyroid psychosis is uncommon. Our literature search shows only three cases of hypothyroid psychosis developed within 3 months after the radioiodine treatment. Our case represents the first case of radioiodine-induced hypothyroidism presenting as psychosis much later (14 years) after the radioiodine treatment. A 60-year-old Chinese lady, with long-standing prim...

Hyperthyroidism is a common disease and one of the best methods for its treatment is radioiodine therapy. Treatment with antithyroid drugs brings patients to euthyroidism before radioiodine therapy. Antithyroid drugs should be discontinued before radioiodine therapy to increase thyroid uptake. The purpose of this study was to determine the optimal time of methimazole (MTZ) discontinuation...

UNLABELLED We studied the scintigraphic and associated clinical characteristics of radioiodine breast uptake in nonbreastfeeding thyroid cancer patients undergoing routine whole-body radioiodine scanning. METHODS We performed a retrospective review of the radioiodine scans and medical records of 30 prospectively collected cases. RESULTS Twenty-three nonpregnant patients had discontinued bre...

Radioiodine therapy is known as the most effective treatment of differentiated thyroid carcinoma (DTC) to ablate remnant thyroid tissue after surgery. In patients with DTC treated with radioiodine, internal radiation dosimetry of radioiodine is useful for radiation risk assessment. The aim of this study is to describe a method to estimate the absorbed dose to the blood using medical internal ra...

OBJECTIVE To evaluate the role of lithium (Li) as an adjuvant in radioiodine therapy of hyperthyroidism. METHODS A randomized controlled trial was carried out on 350 hyperthyroid patients with a mean follow-up period of 32.3 +/- 9.8 months (range, 12-60 months). The patients were randomized into two groups with 175 patients in each group: (1) radioiodine group (controls)-no lithium was given ...
