Radioiodine (RAI)-refractory thyroid cancer is an uncommon entity, occurring with an estimated incidence of 4-5 cases/year/million people. RAI refractoriness is more frequent in older patients, in those with large metastases, in poorly differentiated thyroid cancer, and in those tumors with high 18-fluordeoxyglucose uptake on PET/CT. These patients have a 10-year survival rate of less than 10%. In recent years, new therapeutic agents with molecular targets have become available, with multikinase inhibitors (MKIs) being the most investigated drugs...

PURPOSE: To determine the thyroid clearance effective half-life (Ʈ) with a common handheld electronic dosimeter (ED) in patients undergoing radioiodine treatment for hyperthyroidism. METHODS: Dose rates from twelve inpatients were measured daily with an ED and with a clinical uptake counter. The ED was attached to the patient with two different setups, one using a cervical collar and another employing a neck strap. Estimation of Ʈ was performed by linear regression analysis of the log of both the ED and the uptake counter measurements versus time...

BACKGROUND Ankylosing spondylitis (AS) is a chronic inflammatory disease that predominantly affects the axial skeleton. The ability of anti-TNF-α agents to reduce disease activity in patients with axial spondyloarthritis (axSpA), including AS, has been demonstrated in multiple randomized trials and several meta-analyses. Reports on the efficacy of rituximab in treatment of AS have described good results. We report on a patient with AS who failed anti-TNF-α therapy but showed good clinical improvement with rituximab therapy...

Currently, patients with radioiodine refractory differentiated thyroid cancer (RAIR-DTC) have limited treatment options. In this study, we aimed to assess the short-term efficacy and safety of apatinib in RAIR-DTC. Ten adult patients were prospectively enrolled to receive oral apatinib (750 mg q.d). The primary endpoints were change in serum thyroglobulin (Tg) concentration, disease control rate (DCR) and objective response rate (ORR) based on RECIST 1.1 criteria. The secondary endpoints included change in glucose metabolism, evaluated by maximum standard uptake value (SUVmax), and safety...

PURPOSE: Exercise-induced arterial hypoxemia (EIAH) has been reported in patients with juvenile thyroid cancer treated with radioiodine for lung metastases. This retrospective study tested the hypothesis that EIAH is due to ventilation-perfusion-mismatch in this rare pulmonary condition. METHOD: 50 patients (age 13 -23 years) treated for juvenile thyroid carcinoma and lung metastasis with 131I and 24 controls with thyroid cancer but without lung metastases and prior 131I-treatment were assessed in a state of acute hypothyroidism by computed tomography of the lungs, pulmonary function testing, cardiopulmonary exercise test with measurements of gas exchange, oxygen saturation, alveolar-arterial difference in pO2 (p(A-a)O2) and pCO2 (p(ET-a)CO2)...

INTRODUCTION: Diagnostic I-123 scans have been shown to underestimate the disease burden in differentiated thyroid cancer (DTC) when compared to I-131 post treatment scans, especially in children and patients who have had prior Radioiodine (RAI) therapy and/or distant metastasis.I-124 PET/CT has been shown to be highly effective in imaging DTC related metastatic disease. METHODS: We performed a systematic review and meta-analysis of studies investigating the sensitivity and specificity of I-124 PET/CT in identifying lesions amenable to RAI therapy as confirmed by I-131 post-treatment scanning...

BACKGROUND: Radioiodine ((131) I) is effective treatment for hyperthyroidism in cats, but optimal dose to restore euthyroidism without inducing hypothyroidism is unclear. Treatment-induced hypothyroidism can lead to azotemia and reduced duration of survival. OBJECTIVE: To compare efficacy and short-term outcomes of low-dose (131) I versus higher, standard-dose (131) I as treatment for hyperthyroidism. ANIMALS: A total of 189 client-owned cats undergoing (131) I treatment for mild-to-moderate hyperthyroidism (serum T4 ≥ 4...

BACKGROUND: The ATA guidelines do not recommend prophylactic central compartment neck dissection in patients with T1-T2 papillary thyroid carcinoma (PTC) with no clinical evidence of lymph node metastasis, however patients' staging is recommended. Lymph node metastasis may be present also in small PTC, but preoperative ultrasound identifies suspicious cervical lymphadenopathy in 20-30% of patients. The role of sentinel lymph node biopsy (SLNB) remain open to debate. It has been shown that the identification rate of SLN in PTC patients is improved using a radiotracer compared to a dye technique...

AIMS: When a fixed activity of radioiodine is given for differentiated thyroid cancer (DTC), absorbed doses of radioiodine can vary widely and are not usually measured. Leeds Cancer Centre has routinely used a form of lesion-specific dosimetry for radioiodine patients. This study investigated if the results of dosimetry influenced treatment decisions for patients with advanced DTC. MATERIALS AND METHODS: Since 2005, patients with regionally advanced/metastatic DTC, who underwent radioiodine treatment together with dosimetry, were included in this study...

OBJECTIVE: Amiodarone-induced thyrotoxicosis (AIT) is caused by aminodaroneas a side effect of cardiovascular disease treatment. Based on the differences in their pathological and physiological mechanisms, many methods have been developed so far to differentiate AIT subtypes such as color flow Doppler sonography (CFDS)and 24 h radioiodine uptake (RAIU). However, these methods suffer from inadequate accuracy in distinguishing different types of AITs and sometimes lead to misdiagnosis and delayed treatments...

Radioiodine has served an important role in the diagnostic workup and treatment of patients with differentiated thyroid cancer for more than 6 decades. The interpretation of radioiodine scintigraphic studies should be performed in conjunction with a comprehensive history, histopathologic correlation, and pertinent laboratory values, as well as correlation with available anatomic images and the findings from physical examination. A thorough understanding of the physiology and biodistribution of radioiodine is critical when interpreting radioiodine scintigraphic studies to avoid misinterpretation of physiologic and nonthyroid pathologic variants as thyroid cancer metastases...

Background. Use of radioactive iodine (RAI) ablation has been reported to vary significantly between studies. We explored variation in RAI ablation care patterns between seven thyroid cancer treatment centers in Canada. Methods. The Canadian Collaborative Network for Cancer of the Thyroid (CANNECT) is a collaborative registry to describe and analyze patterns of care for thyroid cancer. We analyzed data from seven participating centers on RAI ablation in patients diagnosed with well-differentiated (papillary and follicular) thyroid cancer between 2000 and 2010...

INTRODUCTION: Radioiodine ablation of remnant thyroid tissue is an important adjuvant therapy of differentiated thyroid carcinoma (DTC) after thyroidectomy. Elevated serum thyroid-stimulating hormone (TSH) level is necessary for successful ablation. The optimum level of serum TSH level necessary for successful radioiodine ablation of well-DTC is, however, yet to be defined. We aimed to determine whether higher serum TSH level will result in a better rate of complete ablation of well-DTC using iodine-131 (I) following initial thyroidectomy...

: Metastatic thyroid cancer is an uncommon condition to be present at the time of pregnancy, but presents a challenging paradigm of care. Clinicians must balance the competing interests of long-term maternal health, best achieved by iatrogenic hyperthyroidism, regular radioiodine therapy and avoidance of dietary iodine, against the priority to care for the developing foetus, with inevitable compromise. Additionally, epidemiological and cellular data support the role of oestrogen as a growth factor for benign and malignant thyrocytes, although communicating the magnitude of this risk to patients and caregivers, as well as the uncertain impact of any pregnancy on long-term prognosis, remains challenging...

Radionuclide therapy using I-131 is commonly used for the treatment of benign thyroid diseases. The therapeutic dose to be administered is calculated based on the type of disease, the volume of the thyroid, and the measured uptake percentage. This methodology assumes a similar biological half-life of iodine, whereas in reality a large variation in biological half-life is observed. More knowledge about the actual biological half-life of iodine for individual patients will improve the quantification of the delivered radiation dose during radioiodine therapy and could aid the evaluation of the success of the therapy...

PURPOSE: Recent studies have suggested that a low dose (LD) of radioiodine (RAI) is sufficient to treat differentiated thyroid cancer (DTC) even in patients with intermediate risk. However, these studies evaluated the efficacy of RAI therapy, irrespective of the results of the whole-body scan (WBS). The aim of the present study was to evaluate the response to LD and high-dose (HD) RAI therapy using two different criteria (with and without WBS results) and the reclassification system according to the revised 2015 guidelines of the American Thyroid Association in Korean intermediate-risk DTC patients...

Thyroid cancer is the most common endocrine malignancy, the global incidence rate of which is rapidly rising. Surgery and radioiodine therapies are common and effective treatments only for nonmetastasized primary tumors. Therefore, effective treatment modalities are imperative for patients with radioiodine-resistant thyroid cancer. Honokiol, a biophenolic compound derived from Magnolia spp., has been shown have diverse biological and pharmacological activities, including anti-inflammatory, antioxidative, antiangiogenic, and anticancer properties...

CONTEXT: For many years, total thyroidectomy (TTx) and radioiodine remnant ablation (RRA) represented the initial treatment of differentiated thyroid cancer (DTC). There is currently much debate surrounding the clinical impact of RRA, particularly in low (LR) and intermediate (IR) risk DTC. OBJECTIVE: To evaluate the role of postoperative High-Sensitive Thyroglobulin on L-thyroxine (LT4-HSTg) and postoperative neck ultrasound (nUS) in risk re-stratification and decision to perform RRA...
