OBJECTIVE It is sometimes difficult to assess I-131 lung uptake at the initial I-131 therapy because of strong artifacts from I-131 uptake in the thyroid bed. The aim of this study was to analyze the lung uptake at the second I-131 therapy for lung metastasis in patients who did not have lung uptake at the initial therapy from differentiated thyroid carcinoma (DTC). Then, we also analyzed the r...

Neuroblastoma, which derives from neural crest, is the most common extracranial solid cancer in childhood. The tumors express the norepinephrine (NE) transporters on their cell membrane and take in metaiodobenzylguanidine (MIBG) via a NE transporter. Since iodine-131 (I-131) MIBG therapy was firstly reported, many trails of MIBG therapy in patients with neuroblastoma were performed. Though mono...

This is a retrospective study on clinical course and treatment response of patients with thyroid hot nodule, referred to nuclear medicine department of Shariati Hospital from 1360 to 1377. From the total 58 patients with average age of 43 yr and incidence peak of 40 yr, 81% were female and 19% were male. 64% of the patients were thyrotoxic and 36% were euthyroid at presentation. Thyrotoxi...

OBJECTIVE This study tested the hypothesis that administration of human recombinant thyroid-stimulating hormone (rhTSH: Thyrogen, thyrotropin alpha) could promote iodine-131 ((131)I) uptake in the therapy for metastatic or locally invasive differentiated thyroid cancer (DTC), obviating L-thyroxine suppressive therapy (L-T4) withdrawal and hypothyroidism in patients with advanced disease. METH...

We examined the merits of combinatorial hMUC1 vaccination and hNIS radioiodine gene therapy and evaluated its tumoricidal effects in an animal tumor model. CMNF (CT26 expressing hMUC1, hNIS, and firefly luciferase) cells were transplanted into 28 mice, and 4 and 11 days after tumor challenge, tumor-bearing mice were immunized i.m. with pcDNA3.1 or pcDNA-hMUC1 vaccine and subsequently administer...

differentiated thyroid carcinomas usually show good uptake and response to i-131 ablative treatment. in this study, 90 patients following near total thyroidectomy who were referred to our institute for i-131 therapy are retrospectively studied. the patients are divided in two groups. group 1 revealed complete ablation after one dose of i-131. group 2 needed more than one dose of i-131 for ablat...

BACKGROUND Radioactive iodine (I-131) is routinely used for the treatment of differentiated thyroid cancer following surgery. Drug-induced liver injury (DILI) is a leading cause of acute liver failure. Here we reported a rare case of diffuse hepatic uptake (DHU) of radioactive iodine (I-131) induced hepatotoxicity in patient with I-131 ablation therapy after thyroidectomy. CASE PRESENTATION A...

CONTEXT Data from a large cohort of patients with pulmonary metastases from differentiated thyroid cancer (DTC) were retrospectively analyzed. OBJECTIVE To assess the effect of radioiodine therapy and investigate the prognostic factors of survival for patients with pulmonary metastasis secondary to DTC. METHODS A total of 372 patients with pulmonary metastasis from DTC treated with (131)I e...

UNLABELLED The purpose of this study was to investigate the enhanced therapeutic effect of the combined use of shRNA (small hairpin RNA) therapy for the hexokinase II (HKII) gene and (131)I human sodium iodide symporter (hNIS) as a gene therapy for in vitro and in vivo treatment of anaplastic thyroid carcinoma cells (ARO) in an animal model. METHODS A recombinant lentivirus containing a plasm...
