OBJECTIVE: In the follow-up of patients with differentiated thyroid cancer (DTC), several patients had elevated serum levels of antithyroglobulin antibody (TgAb), undetectable serum thyroglobulin (Tg), and negative radioiodine whole body scan (131 I-WBS). We describe the use of neck ultrasonography (US) and fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) imaging in these patients to investigate this clinically challenging problem and propose treating...

Radioiodine therapy in the treatment of differentiated thyroid carcinoma (DTC) is used in clinical practice for the ablation of thyroid residues and/or destruction of tumour tissue. Whole-body scintigraphy for visualization of the spatial 131I distribution performed by a gamma camera (GC) is a standard procedure in DTC patients after application of radioiodine therapy. A common problem is the precise topographic localization of regions where radioiodine is accumulated even in SPECT imaging. SPECT/CT can provide precise topographic localization of regions where radioiodine is accumulated, but it is often unavailable, especially in developing countries because of the high price of the equipment...

BACKGROUND: An elevated thyroid stimulating hormone (TSH) level is essential for the uptake of radioiodine into thyroid remnants and residual thyroid cancer in patients undergoing high-dose radioiodine therapy (HD-RIT). Recently, the use of recombinant human thyroid stimulating hormone (rh- TSH) has increased in preference over the conventional method of thyroid hormone withdrawal (THW). However, the clinical influences of the two methods, aside from the therapeutic effects, have not been widely evaluated...

CONTEXT: The number of metastatic lymph nodes (LNs) and the ratio of metastatic LN (LR) have been reported as predictors of recurrence in papillary thyroid carcinoma (PTC), while the role of LR or the number of metastatic LNs on the clinical response remains unclear. OBJECTIVE: We aimed to compare the prognostic value of LR and the number of metastatic LNs on clinical response in PTC. DESIGN/SETTING/PATIENTS: A total of 384 PTC patients with LN metastases were enrolled in this study, all of whom underwent total or near total thyroidectomy and subsequent radioiodine ablation...

INTRODUCTION: Due to a limited number of hospital beds dedicated to radioiodine therapy (RIT) in some countries, a fractionated dose of radioiodine may be considered as the ablation therapy of differentiated thyroid cancer (DTC). The aim of the study was to compare the late effects of ablation therapy with single and fractionated dose of radioiodine in patients with DTC. PATIENTS AND METHODS: Patients with low-risk DTC referred to our institution 5-16 weeks after thyroidectomy, treated with 2...

OBJECTIVES: To assess the yield of neck ultrasound (US) when serum thyroglobulin (Tg) is undetectable (<0.1 ng/mL) compared to elevated serum Tg in patients with differentiated papillary thyroid carcinoma (PTC) treated with thyroidectomy and radioactive iodine 131 (RAI) ablation. METHODS: A retrospective chart review was conducted from 2010 through 2015 at an academic institution evaluating US results in patients with serum Tg levels obtained within 6 months of a neck US examination after thyroidectomy and RAI...

Background Monopolar radiofrequency ablation is currently deemed an exotic treatment option for benign thyroid nodules in many central European countries. The aim of this study was to prospectively evaluate safety and efficacy of this method in a large patient cohort following its introduction in Austria. Patients and methods Peri- and post-interventional complications were analyzed for 277 patients. Efficacy was determined for 300 and 154 nodules at, respectively, 3 and 12 months post-treatment. All treatments were performed with an internally-cooled 18G radiofrequency electrode using a free-hand, so-called "moving-shot" technique following subcutaneous and local perithyroidal anesthesia...

RATIONALE: Long-term recurrence rate of differentiated thyroid carcinoma has been reported to be as high as 30%. Repeat surgery may be challenging due to normal tissue plane distortion secondary to postoperative fibrosis, especially for small-sized recurrences. Recently, radiofrequency ablation (RFA) has been suggested to be a safe and effective alternative for high-risk patients or those who refuse surgery. Nonetheless, the efficacy of RFA remains questionable for densely calcified lymph nodes, which would have an increased likelihood of leaving residues after RFA...

PURPOSE: To investigate the use of conventional ultrasound and contrast-enhanced ultrasound (CEUS) in assessing local therapeutic response of percutaneous laser ablation (PLA) for papillary thyroid microcarcinoma (PTMC). METHODS: Sixty-four patients with 64 PTMCs who were referred to our hospital from November 2013 to July 2016 were treated with PLA. The extent of ablation was assessed by CEUS at 10-20 min and 7 days after PLA. The size and volume of the ablation zone were evaluated on conventional ultrasound at 1 h, 1, 3, 6 and 12 months, and every half-year thereafter, and recurrences were also recorded...

Thyroid cancer is an endocrine malignancy whose prevalence is increasing in the United States. Nearly 57,000 new cases of thyroid cancer are estimated to be diagnosed in 2017. The standard of care for differentiated thyroid cancer is thyroidectomy followed by ablation of thyroid remnants with high-dose radioactive iodine (131 I). Apart from thyroid glands,131 I accumulates in cells of salivary glands and compromises its function. Xerostomia is, therefore, a frequent and often persistent complaint of patients...

PURPOSE: Thyroid dysfunction affects the outcomes of atrial fibrillation (AF) catheter ablation. However, it remains unclear if the variations in thyroid function, especially in the triiodothyronine levels, are associated with AF recurrence in euthyroid subjects. This study investigated the associations of thyroid hormone levels with arrhythmia recurrence after AF catheter ablation in euthyroid patients. METHODS: A total of 1115 consecutive AF patients who underwent catheter ablation were prospectively enrolled and had their thyroid function measured prior to the procedure...

Differentiated thyroid cancer (DTC) has a good prognosis overall; however, lifelong follow-up is required for many cases. Radioiodine planar imaging with iodine-123 (I-123) or radioiodine-131 (I-131) remains the standard in the follow-up after initial surgery and ablation of residual thyroid tissue using I-131 therapy. Radioiodine imaging is also used in risk-stratifying and for staging of thyroid cancer, and in long-term follow-up. Unfortunately, the lack of anatomical detail on planar gamma camera imaging and superimposition of areas presenting with increased radioiodine uptake can make accurate diagnosis and localization of radioiodine-avid metastatic disease challenging, leading to false positive results and potentially to over-treatment of patients...

BACKGROUND: Women of reproductive age with differentiated thyroid cancer (DTC) often need to receive radioactive iodine (RAI) treatment after surgery. In contrast to the well documented effect of RAI on testicular function, the potential negative effects of this treatment on ovarian reserve have been largely dismissed. The objective of this pilot study was to examine the possibility that RAI treatment is deleterious to the ovarian reserve by prospectively measuring the concentration of anti-Müllerian hormone (AMH) after this treatment...

RATIONALE: Iodine-131 (I-131) is a sensitive marker for the detection of differentiated thyroid cancer (DTC). I-131 whole-body scintigraphy (WBS) has been used widely in evaluation of DTC patient. However, I-131 WBS exists many false-positive uptake of I-131 because radioiodine uptake can also be seen in healthy tissue or in a variety of benign and malignant non-thyroidal tumors. PATIENT CONCERNS: A 44-year-old woman with a papillary thyroid carcinoma for the purpose of ablation therapy after a total thyroidectomy...
