Background This study was conducted to compare the staging systems for the prediction of long-term disease status in patients with well-differentiated thyroid carcinoma (WDTC), and find out the earliest postoperative period predictor of long-term persistence/recurrence of disease. Methods Patients with WDTC (n=356, age 41.5 ± 12.7 years) followed for at least 5 years (12.3 ± 5.0 years) after thyroidectomy and 131I remnant ablation at a tertiary regional hospital in Taiwan were retrospectively studied. Each patient was risk-stratified using the American Joint Cancer Committee (AJCC) (stage I-IV), American Thyroid Association (ATA) (low, intermediate, high risk) staging systems after operation and first 131I remnant ablation and using response to initial therapy reclassification (RTR) (excellent, indeterminate, biochemical incomplete, structural incomplete response) system, which is determined 6-24 months after the first 131I ablation...

As a co-receptor for vascular endothelial growth factor‑3 (VEGF‑3), neuropilin receptor type‑2 (NRP‑2) plays a central role in lymphangiogenesis and angiogenesis. Recently, mounting data of evidence show that NRP‑2 is overexpressed in several human cancers, and its overexpression is often associated with poor prognosis. Therefore, it is necessary for us to develop an affinity reagent for noninvasive imaging of NRP‑2 expression because it may be possible to provide early cancer diagnosis, more accurate prognosis, and better treatment planning...

PURPOSE: The aims of the current study were to explore plasma lncRNAs as a novel biomarker panel for the diagnosis of non-131I-avid lung metastases of PTC and to investigate the plasma lncRNA expression levels associated with survival in PTC patients with lung metastases. METHODS: The expression of lncRNAs was examined using an lncRNA microarray chip. The lncRNAs with the most significant difference in expression between PTC patients with non-131I-avid lung metastases and PTC patients with 131I-avid lung metastases were verified by quantitative reverse-transcription polymerase chain reaction...

BACKGROUND: Little objective pediatric data exist to guide the optimal time needed to achieve thyroid-stimulating hormone (TSH) levels ≥30 μIU/mL prior to performing 131I or 123I whole-body scan (WBS) imaging in children with thyroid cancer in the post-thyroidectomy period or after hormone discontinuation. METHODS: Retrospective study of patients aged 5-19 years who underwent WBS. Patient data collection included type and duration of withdrawal (liothyronine [L-T3], levothyroxine [L-T4], or post-thyroidectomy status without hormonal replacement) and TSH measured prior to WBS (level and timing)...

A 66-year-old woman with a history of papillary thyroid cancer status after total thyroidectomy underwent I radioiodine ablation therapy 3 months after surgery. Posttherapy whole body planar imaging revealed focal intense I uptake in the posterior right abdomen. SPECT/CT of this region localized the uptake to the medial lower pole of the right kidney. Further evaluation with MRI demonstrated a correlative suspicious right renal mass. The patient underwent right partial nephrectomy with pathology demonstrating that the renal mass was of thyroidal origin (papillary subtype)...

PURPOSE: TgAb have been proposed as tumor markers in DTC. Recent evidence links TgAb levels with DTC aggressiveness. We aimed to evaluate the relationship between TgAb and tumor glucose metabolism in DTC patients. METHODS: Seventy-one DTC patients who underwent (18)F-FDG PET/CT were included. According to TgAb value and trends, patients were divided into TgAb positive (TgAb+) or negative (TgAb-) as well as in patients with increasing (Inc-TgAb) or decreasing (Dec-TgAb) trend...

Metal-organic complexes (MOCs) are emerging developing functional materials, the different categories of metal ions and organic biomolecules provide great possibilities for the morphologies, sizes, and properties of the products. Enlightened by the previous works of folate-nickel nanotubes (FA-Ni NTs), herein, a series of metal ions are tested to coordinate with folate (FA) by the solvothermal method, among which the folate-cobalt(II) complex is formed to be a scaffold for the nanotube with the length of 150-500 nm and inner diameter of 6-11 nm, while the other metal ions fail...

Interpretation of iodine I whole-body scintigraphy can be challenging, as there are many nonpathologic findings that may present with increased radiotracer uptake. Radiotracer uptake has been reported in the literature involving the salivary glands, thymus, renal cysts, skin contamination, and other benign etiologies. We present the case of an incidental right wrist ganglion cyst demonstrating persistent increased uptake on I whole-body scintigraphy.

OBJECTIVE: Radioactive iodine therapy (RAIT) is established as an efficient means of treating toxic goiter (TG) globally. The field of nuclear medicine (NM) still appears novel to many Nigerian clinicians and patients. A culturally embedded dread of radiation may raise ethical and moral concerns about potential adverse effects in the wake of RAIT in our setting. An adverse drug reaction may be described as "a response to a drug which is noxious and unintended, and which occurs at doses normally used in man"...

A 65-year-old woman presented with increased human thyroglobulin (3.3 ng/mL) 5 years after resection of a papillary thyroid carcinoma and successful I radioiodine therapy. I whole-body scintigraphy showed a small focus ventrally in the right lower neck, leading to suspicion of a papillary thyroid carcinoma recurrence. I-PET/CT and real-time PET/US fusion matched to a small hypoechoic/anechoic ovoid structure situated between the right sternoclavicular joint and the brachiocephalic trunk. After surgical resection, histology allowed a diagnosis of thymic cyst...

Cardiovascular system is essentially affected by thyroid hormones by way of their genomic and non-genomic effects. Untreated overt thyroid dysfunction is associated with higher cardiovascular risk. Although it has been studied more than 3 decades, in subclinical thyroid dysfunction the negative effect on cardiovascular system is much more controversial. Large meta-analyses within last 10 years have shown that subclinical hyperthyroidism is associated with higher cardiovascular risk than subclinical hypothyroidism...

: SPECT/CT detects radioiodine-positive cervical lymph node metastases (LNMs) of differentiated thyroid carcinoma (DTC) at the time of postsurgical radioablation (RA). Preliminary evidence indicates that the majority of LNMs are successfully treated by RA. The aim of this study was to confirm this evidence in a bicentric setting and to evaluate whether size is a predictor for successful elimination. PATIENTS AND METHODS: Since 01/2007 and 05/2008, respectively, SPECT/spiral-CT is performed routinely in all patients with DTC at RA in two University Clinics...

: Germany has developed into a country with a nationwide largely sufficient iodine supply due to improved alimentary iodine supply. The reduction of iodine uptake in focal autonomies induced by reduced iodine avidity was evaluated by Gotthardt et al. 2006, showing a significant decline of pertechnetate uptake up to the year 2004. AIM: This study was intended to carry this investigation forward to the present day to analyze the course of a conjectural stabilization of iodine uptake values...
