UNLABELLED Technical aspects and results of the dosimetric assessments of postoperative radioiodine ablation in the framework of an international, prospective, controlled, randomized, comparative study of the effectiveness of ablation therapy with 3.7 GBq (131)I in differentiated thyroid cancer after stimulation with recombinant human TSH (rhTSH) or by thyroid hormone withdrawal (THW) are prese...
RATIONALE Post-therapy or diagnostic whole-body radioiodine scintigraphy is widely employed to evaluate the residual, recurrence, or metastases of differentiated thyroid carcinoma because of the high sensitivity and accuracy. However, it has pitfalls. PATIENT CONCERNS We described a 63-year-old male with a history of papillary thyroid carcinoma who was referred for iodine-131 ablation therapy...
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...
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...
Introduction:The maximum tolerable activity (MTA) of I-131 in radioiodine therapy is an established surrogate quantity to ensure that the therapeutic activity does not produce severe damages to the bone marrow and lung. The aim of this study was to estimate the MTAs for high-risk patients using I-124 pre-therapy dosimetry and to compare the results with published literature. <...
Radioiodine uptake is not commonly seen by the thymus gland. On the contrary, the gland is slowly replaced by fat after puberty. Herein, we present 2 patients with papillary thyroid carcinoma, follicular variant, and cervical lymph node involvement. After total/near-total thyroidectomy, the patients received I for ablation therapy. On posttreatment radioiodine scintigraphy, mediastinal I uptake...
INTRODUCTION Radioactive iodine has been used for more than 50 years for the treatment of thyroid diseases. Differentiated thyroid cancers have the ability to trap iodine. Therefore, radioiodine can be used both diagnostically and therapeutically. In the follow-up of patients, it is critical to interpret radioiodine scans correctly. CASE PRESENTATION Non-physiological Iodine-131 (I-131) extra...
Introduction. Although follicular thyroid carcinoma is a rare malignant tumor, up to 20% of the patients are threatened by potential complications resulting from infiltrating tumor growth into surrounding tissues. Case report. A 66year-old female came to hospital with the presence of a growing thyroid nodule of the left lobe. Ultrasonic examination showed a 8 cm hypoechoic nodule in the left lo...
Diagnostic whole-body scan is a standard procedure in patients with thyroid cancer prior to the application of a therapeutic dose of 131I. Unfortunately, administration of the radioisotope in a diagnostic dose may decrease further radioiodine uptake-the phenomenon called "thyroid stunning". We estimated radiation absorbed dose-dependent changes in genetic material, in particular in the sodium i...
