REVIEW
Maureen Hatch, Elisabeth Cardis
2016 marked the 30th anniversary of the Chernobyl Nuclear Power Plant accident. We and others wrote reviews for the 25th anniversary. Since then, additional papers have appeared and it seems timely to highlight lessons learned. To present, not a systematic review, but a commentary drawing attention to notable findings. We include not only recent reports and updates on previous results, but key findings from prior Chernobyl studies. The dose-dependent increase in Papillary Thyroid Cancer (PTC) following childhood I-131 exposure in Ukraine and Belarus has now been shown to persist for decades...

Although radioiodine (131-I) can be used as treatment of hyperthyroidism for patients in hemodialysis, its use is limited and the experience is mainly related to differentiated thyroid carcinoma. We report a 58 years old female on hemodialysis with recurrent hyperthyroidism after propylthiouracil treatment. She was successfully treated with 131-I and four months after the intervention her euthyroid state was confirmed. We measured 131-I activity in blood, dialysate liquid and other waste products, as well as patient radiation exposure rates...

Renal metastasis of thyroid cancer is extremely rare. We report the case of a 62-year-old woman with Hürthle cell thyroid cancer (HCTC) with lungs, bones, and bilateral kidneys metastases. The renal metastatic lesions were clearly demonstrated by (131)I whole body scan (WBS) with SPECT/CT. However, they exhibited false-negative results in (18)F-FDG PET/CT, kidney ultrasonography, and contrast-enhanced CT scan. The findings imply that tumors have low glucose metabolism and are able to accumulate radioiodine, which is not commonly found in the relatively aggressive nature of HCTC...

In 2005, the term theragnostics (theranostics) was introduced for describing the use of imaging for therapy planning in radiation oncology. In nuclear medicine, this expression describes the use of tracers for predicting the absorbed doses in molecular radiotherapy and, thus, the safety and efficacy of a treatment. At present, the most successful groups of isotopes for this purpose are (123)I/(124)I/(131)I, (68)Ga/(177)Lu, and (111)In/(86)Y/(90)Y. The purpose of this review is to summarize available data on the dosimetry and dose-response relationships of several theranostic compounds, with a special focus on radioiodine therapy for differentiated thyroid cancer and peptide receptor radionuclide therapy...

Neeta Pandit-Taskar, Shakeel Modak
The norepinephrine transporter (NET) is essential for norepinephrine uptake at the synaptic terminals and adrenal chromaffin cells. In neuroendocrine tumors, NET can be targeted for imaging as well as therapy. One of the most widely used theranostic agents targeting NET is metaiodobenzylguanidine (MIBG), a guanethidine analog of norepinephrine. (123)I/(131)I-MIBG theranostics have been applied in the clinical evaluation and management of neuroendocrine tumors, especially in neuroblastoma, paraganglioma, and pheochromocytoma...

Theranostics, a modern approach combining therapeutics and diagnostics, is among the most promising concepts in nuclear medicine for optimizing and individualizing treatments for many cancer entities. Theranostics has been used in clinical routines in nuclear medicine for more than 60 y-as (131)I for diagnostic and therapeutic purposes in thyroid diseases. In this minireview, we provide a survey of the use of 2 different radioiodine isotopes for targeting the sodium-iodine symporter in thyroid cancer and nonthyroidal neoplasms as well as a brief summary of theranostics for neuroendocrine neoplasms and metastatic castration-refractory prostate cancer...

Iodine 131 (I-131), the principal component of nuclear fallout from the Chernobyl accident, concentrates in the thyroid gland and may pose risks to fetal development. To evaluate this, neonatal outcomes following the accident in April of 1986 were investigated in a cohort of 2582 in utero-exposed individuals from northern Ukraine for whom estimates of fetal thyroid I-131 dose were available. We carried out a retrospective review of cohort members' prenatal, delivery and newborn records. The relationships of dose with neonatal anthropometrics and gestational length were modeled via linear regression with adjustment for potentially confounding variables...

BACKGROUND: The purpose of this study was to evaluate the association between radioiodine (I-131) therapy for thyroid cancer and the risk of stroke in Taiwan. METHODS: A total of 10 104 of the patients aged 20 years or older, who were newly diagnosed with thyroid cancer during 2000-2010, were recruited and classified into 2 cohorts according to whether they received I-131 therapy through 1:1 propensity score matching. The cumulative Kaplan-Meier curves for the incidence of stroke in the 2 cohorts were compared using the log-rank test...

Amiodarone is a di-iodinated benzofuran derivative and is classified as a class III antiarrhythmic agent. It is one of the most powerful and effective antiarrhythmics, being a first-line agent due to its ability to treat ventricular and supraventricular dysrhythmias; since 1960 the drug has become one of the most frequently prescribed antiarrhythmics, despite its potentially serious, side effects. By far, one of the most challenging condition is the thyroid pathology induced by this drug. Each 200 mg tablet of amiodarone contains approximately 75 mg of iodine, 3-10% from each tablet being released as free iodine...

Ultrasound biomicroscopy (UBM) remains a potent tool in the diagnosis and characterization of uveal lesions. In the setting of malignancy, it can confirm both placement of and response to brachytherapy. We present a case of iris melanoma with aggressive BAP-1 mutation, treated successfully with I-131 brachytherapy which was both characterized and followed with UBM and thereafter discuss the current state of these modalities.

Ambient gamma dose rate (GDR) is the primary observation quantity for nuclear emergency management due to its high acquisition frequency and dense spatial deployment. However, ambient GDR is the sum of both cloud and ground shine, which hinders its effective utilization. In this study, an automatic method is proposed to identify the radioactive plume passage and to separate the cloud and ground shine in the total GDR. The new method is evaluated against a synthetic GDR dataset generated by JRODOS (Real Time On-line Decision Support) System and compared with another method (Hirayama, H...

PURPOSE: Due to variations in biological half-life, accurate thyroid dosimetry for I-131 therapy is not trivial in clinical practice. In recent publications, systems are described to measure the uptake of I-131 in the thyroid repeatedly over time. In this work, we present a method to calculate patient specific pharmacokinetics and absorbed dose using such a collar detector system (CoTI) in combination with a SPECT acquisition and a two-compartment model fit. METHODS: For three patients receiving I-131 therapy for benign thyroid conditions, the complete uptake profile is measured over a period of 15 to 25 days after administration...

A common complication of radioiodine (I(131)) treatment of thyroid cancer is parotitis. Here we describe our clinical experience in treating delayed I(131)-induced parotitis using sialoendoscopy together with an internal stent and postoperative massage. In this retrospective cohort study we reviewed 32 patients who were treated in that way under general anaesthesia between July 2010 and March 2015. Their age, sex, and the time to development of the parotitis were collected from the hospital's database. All patients were evaluated using a visual analogue scale (VAS), sialography, and computed tomography preoperatively...

PURPOSE: The optimal management of central nervous system (CNS) relapse of rhabdomyosarcoma (RMS) is unclear. We examined diagnosis, management, and outcomes of patients with RMS developing CNS relapse. METHODS: Records of 23 patients diagnosed with CNS relapse between 1999 and 2016 were reviewed. Median age at presentation of CNS relapse was 15 years (range, 1-34 years). High-risk features at initial presentation were as follows: 16 alveolar patients, 13 Stage IV, and 13 with primary tumor in parameningeal locations...

OBJECTIVE: Measurement of recombinant human thyrotropin (rhTSH)-stimulated thyroglobulin (Tg) is generally recommended 72 h after the second rhTSH injection. However, due to the acute effect of I-131 on thyrocytes, Tg measured after radioiodine therapy (RIT) would not accurately reflect the thyroid tissue burden. We aimed to determine predictive values of serum Tg level measured just before rhTSH-aided RIT and to compare the results obtained just after RIT in patients with differentiated thyroid carcinoma (DTC)...

OBJECTIVE: The aim of this study was to assess I-131 biokinetics in thyroid cancer and remnant tissue in patients with differentiated thyroid cancer using whole-body scan (WBS) and SPECT images acquired after I-131 therapy. The influence of thyroid stimulating hormone (TSH) stimulation method on the kinetics was also evaluated. METHODS: A total of 57 patients who received I-131 therapy (2.96-7.4 GBq) were retrospectively included. TSH stimulation was achieved by recombinant human thyrotropin (rhTSH) or by thyroid hormone withdrawal (THW)...

To evaluate risk of thyroid neoplasia nearly 30 years following exposure to radioactive iodine (I-131) from the 1986 Chernobyl nuclear accident, we conducted a fifth cycle of thyroid screening of the Ukrainian-American cohort during 2012-2015, following four previous screening cycles started in 1998. We identified 47 thyroid cancers (TC) and 33 follicular adenomas (FA) among 10,073 individuals who were <18 years at the time of the accident and had a mean I-131 dose of 0.62 Gy. We found a significant I-131 dose response for both TC and FA, with an excess odd ratio per Gy of 1...

PURPOSE: This article examines the outcome of radioactive iodine ablation therapy for thyroid cancer in high-risk patients and investigates background factors influencing ablation failure. MATERIALS AND METHODS: We included 91 patients in this retrospective analysis and evaluated the ablation success rate. Successful ablation was defined as the absence of visible iodine-131 (I-131) accumulation in the thyroid bed after whole-body scans and thyroglobulin levels <2 ng/ml in a TSH-stimulated state after ablation...
