A 12-year-old girl presented with a history of cervical mass, and one week of throat discomfort and dyspnea. Five years ago, the patient was diagnosed as Hashimoto's thyroiditis and hyperthyroidism; she received antithyroid drug treatment, but the result was not satisfactory. B-ultrasonic showed that the size of thyroid gland was 8.1 cm×3.2 cm in the left and 8.2 cm×4.8 cm in the right. After iodine 131 combined with radiofrequency ablation (RFA) treatment, throat discomfort and recumbent breathing difficulties disappeared, and B-ultrasonic showed that the size of thyroid reduced to 2...

Accumulating evidence indicates that cancer stem cells (CSCs) are the cause of tumor drug/radio-resistance or distant metastasis; therefore, it is essential to eliminate CSCs to cure cancer completely. The purpose of this study was to utilize radioimmunotherapy (RIT) to target CD133(+) colonic CSCs and observe whether this prevented tumor development, by assessing the maximum tolerated dose (MTD) of HCT116 tumor-bearing nude mice with escalating doses of 131I-AC133.1 monoclonal antibody (mAb), and determining the therapeutic efficacy of RIT with 131I-AC133...

BACKGROUND: Patients with newly diagnosed high-risk (HR) neuroblastoma (NBL) still have a poor outcome, despite multi-modality intensive therapy. This poor outcome necessitates the search for new therapies, such as treatment with (131)I-meta-iodobenzylguanidine ((131)I-MIBG). OBJECTIVES: To assess the efficacy and adverse effects of (131)I-MIBG therapy in patients with newly diagnosed HR NBL. SEARCH METHODS: We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library 2016, Issue 3), MEDLINE (PubMed) (1945 to 25 April 2016) and Embase (Ovid) (1980 to 25 April 2016)...

BACKGROUND: 18-Fluorodeoxyglucose positron emission tomography (FDG-PET) has established a role in the evaluation of several malignancies. However, its precise clinical role in the neural crest cell tumors continues to evolve. PURPOSE: The purpose of this study was to compare iodine-131 metaiodobenzylguanidine ((131)I-MIBG) and FDG-PET of head to head in patients with neural crest tumors both qualitatively and semiquantitatively and to determine their clinical utility in disease status evaluation and further management...

To protect bone marrow from over-irradiation, maximum permissible activity (MPA) of iodine-131 ((131)I) to treat thyroid cancer is that which limits absorbed dose to blood (as a surrogate of marrow) to < 200 cGy. The conventional approach (Method-1) requires repeated gamma-camera whole-body measurements along with blood samples. We sought to determine whether reliable MPA values can be obtained by simplified procedures. Methods: Data acquired over multiple time points were examined retrospectively for 65 thyroid cancer patients, referred to determine (131)I uptake and MPA for initial treatment following thyroidectomy (N = 39), including 17 patients with compromised renal function and 22 patients with known (N = 16) or suspected (N = 6) metastases...

BACKGROUND: Chinese data of efficacy of low- and high-dose of radioiodine for thyroid remnant is still absent. The aim of the study is to investigate whether the low-dose of radioiodine is as effective as high-dose for remnant ablation in Chinese patients. METHODS: Patients presenting for radioiodine ablation in our department were included. Inclusion criteria were an age of 16 years or older; total or near total thyroidectomy; tumor-node-metastasis (TNM) stage of pT1-3, any N stage and M0...

Molecular imaging using radiopharmaceuticals has a clear role in visualising the presence and extent of tumour at diagnosis and monitoring response to therapy. Such imaging provides prognostic and predictive information relevant to management, e.g. by quantifying active tumour mass using positron emission tomography/computed tomography (PET/CT). As these techniques require only pharmacologically inactive doses, age and potential frailty are generally not important. However, this may be different for therapy involving radionuclides because the radiation can impact normal bodily function (e...

Integrin α3β1 has been shown to be a novel candidate target for the imaging and specific therapy of non-small-cell lung cancer. We have previously reported on a peptide containing a novel motif of NGXG that specifically binds to the integrin α3 receptor on lung cancer cells using a one-bead one-peptide combinatorial library. In this study, we developed the peptide cNGEGQQc-based therapeutic agent labeling with radionuclide iodine-131 (I) and evaluated its characteristics including stability, biodistribution, antitumor activity, and safety...

INTRODUCTION: Increased body mass index (BMI) is known to be associated with the high prevalence of Differentiated Thyroid Cancers (DTC); however data on its impact on survival outcome after thyroidectomy and adjuvant therapy is scanty. OBJECTIVE: We aimed to evaluate the impact of BMI on overall survival (OS) and disease free survival (DFS) rates in patients with DTC. METHODS: Between 2000 and 2011, 209 patients with DTC (papillary, follicular, hurthle cell) were treated with thyroidectomy followed by adjuvant radioactive iodine-131 (RAI) therapy and thyroid-stimulating hormone (TSH) suppression...

A 25-year-old woman had total thyroidectomy and iodine-131 ablation therapy for papillary thyroid carcinoma. Whole body imaging on the 7(th) day of therapeutic activity demonstrated radioiodine uptake in the remnant tissue and intense heterogeneous uptake at the sacral region prominently in the posterior image. Initial interpretation was suspicious for sacral metastasis. Technetium-99m-methylene diphosphonate bone scan demonstrated normal bone uptake and the absence of left kidney. On blood-pool phase of bone scan, the absence of left renal activity and an extra area of uptake in the sacral region suggestive of pelvic kidney were noticed...

The modern military battlefields are characterized by the use of nonconventional weapons such as encountered in the conflicts of the Gulf War I and Gulf War II. Recent warfare in Iraq, Afghanistan, and the Balkans has introduced radioactive weapons to the modern war zone scenarios. This presents the military medicine with a new area of radioactive warfare with the potential large scale contamination of military and civilian targets with the variety of radioactive isotopes further enhanced by the clandestine use of radioactive materials in the terrorist radioactive warfare...

In the case of a nuclear reactor accident the release contains a high proportion of iodine-131 that can be inhaled or ingested by members of the public. Iodine-131 is naturally retained in the thyroid and increases the thyroid cancer risk. Since the radiation induced thyroid cancer risk is greater for children than for adults, the thyroid dose to children should be assessed as accurately as possible. For that purpose direct measurements should be carried out with age-specific calibration factors but, currently, there is no age-specific thyroid phantoms allowing a robust measurement protocol...

As a result of the nuclear accident at the Fukushima Daiichi nuclear power station (FDNPS) after the Great East Japan Earthquake on March 11, 2011, volatile radionuclides including iodine-131 were released into the environment and contaminated open-field vegetables, raw milk, tap water, etc. It is important for the health care of residents to correctly comprehend the level of their exposure to radioactive substances released following the accident. However, an evaluation of the internal exposure doses of residents of Fukushima Prefecture as a result of the ingestion of foods, which is indicated in the report issued by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR)1 is based on a number of assumptions...

Iodine-131 (I-131) is often used in thyroid diagnostics and therapy. External and internal exposure to radioiodine can lead to molecular and cellular damage in peripheral blood lymphocytes. The aim of this study was to explore the influence of low and high doses of I-131 on susceptibility to ionizing radiation. Study groups consisted of 30 individuals free of thyroid diseases, 41 patients exposed diagnostically to low doses of I-131, and 37 hyperthyroidism patients exposed therapeutically to high doses. The standardized DNA repair competence assay was used to test the efficacy of the fast DNA repair process in G0 cells...

Down syndrome characterized by trisomy of chromosome 21 is frequently associated with thyroid dysfunctions due to underlying autoimmune disorders. Hypothyroidism is the commonest thyroid dysfunction and hyperthyroidism, usually Graves' disease, is far less common. On literature review, we came across approximately 112 cases reported so far with the first such case report in 1946. The published data from India on hyperthyroidism in Down syndrome is of three case reports. We report one such patient, an adult male of 28 years who was administered Iodine-131 as a definitive treatment after 9-10 years of initial diagnosis...

The whole-body iodine-131 scintigraphy is an imaging technique in monitoring patients with a history of thyroid cancer. Although the rate of false positives is negligible, it is not nonexistent. We report the case of an intervened and treated patient for thyroid cancer with good clinical and biochemical response. Scintigraphic findings were consistent with unsuspected bone metastasis. Fused SPECT/CT data allowed accurate diagnosis of giant diaphragmatic hernia associated with intrathoracic stomach, a very rare pathology that can lead to false positive results...

PURPOSE: Adrenal venous sampling is generally considered the gold standard to identify unilateral hormone production in cases of primary hyperaldosteronism. The aim of this study is to evaluate whether the iodine-131-6-β-iodomethyl-19-norcholesterol (NP-59) test may represent an alternative in selected cases. METHODS: Patients submitted to laparoscopic adrenalectomy for suspected primary hyperaldosteronism (n = 27) were retrospectively reviewed. When nuclear medicine tests were preoperatively performed, their results were compared with the histopathologic findings and clinical improvement...
