Qiu C, Wu S, Li J. Central lymph node ratio is an important recurrence prognostic factor for pediatric differentiated thyroid cancer. Front Endocrinol (Lausanne) 2024; 15:1290617. [PMID: 39015179 PMCID: PMC11250549 DOI: 10.3389/fendo.2024.1290617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 06/13/2024] [Indexed: 07/18/2024] Open
Abstract
Background The current risk stratification methods for Pediatric Differentiated Thyroid Carcinoma (DTC) are deemed inadequate due to the high recurrence rates observed in this demographic. This study investigates alternative clinicopathological factors, specifically the Central Lymph Node Ratio (CLNR), for improved risk stratification in pediatric DTC. Methods A retrospective review of 100 pediatric DTC patients, aged 19 or younger, treated between December 2012 and January 2021 at the First Affiliated Hospital of Guangxi Medical University was conducted. Clinicopathological variables were extracted, and univariate logistic regression identified factors correlated with recurrence. Kaplan-Meier (KM) survival analysis and subsequent statistical tests were used to assess the significance of these factors. Results The CLNR, with a cutoff value of 77.78%, emerged as a significant predictor of recurrence. Patients with a CLNR above this threshold had a 5.467 times higher risk of recurrence. The high CLNR group showed a higher proportion of male patients, clinically lymph node positivity (cN1), and extrathyroidal extension (ETE) compared to the low-risk group (p<0.05). Conclusion CLNR is a valuable predictor for recurrence in pediatric DTC and aids in stratifying patients based on Recurrence-Free Survival (RFS). For patients with a high CLNR, aggressive iodine-131 therapy, stringent TSH suppression, and proactive postoperative surveillance are recommended to mitigate recurrence risk and facilitate timely detection of recurrent lesions.

Abstract
Thyroid involvement is rare in pediatric Langerhans cell histiocytosis (LCH). It may cause airway narrowing, leading to acute-onset respiratory distress. Severe cases may require emergent surgical interventions such as thyroidectomy, which should be avoided in children due to higher rates of complication, particularly in infancy. There is currently no consensus on the indications for surgical treatment in LCH with thyroid involvement. In this report, we describe the cases of two children who presented with tracheal stenosis caused by thyroid LCH, both of which were successfully treated by early induction of chemotherapy, and one of which was also treated for a shorter duration. Mutation analysis detected in-frame deletions of BRAF exon 12 in both cases. These cases suggest that timely diagnosis and administration of chemotherapy may alleviate severe airway obstruction and reduce the need for thyroidectomy in pediatric patients with thyroid LCH.

Abstract
OBJECTIVES The Bethesda system for reporting cytopathology (TBSRTC) has been widely adopted in the management of thyroid nodules. Based on the limited pediatric data available, the implied malignancy risk for each of the categories may be significantly different in pediatrics vs. adults, especially in the indeterminate categories (Bethesda Class III or IV). We report the diagnostic utility of fine needle aspiration (FNA) biopsy at our institution based on the Bethesda system and the risk of malignancy in each category. METHODS We retrospectively reviewed all patients who underwent a thyroid FNA at our tertiary pediatric hospital from 12/1/2002 to 11/30/2018. FNA results were classified according to TBSRTC. Patient demographics, cytology, histopathology, radiological and clinical follow-ups were examined. RESULTS A total of 171 patients were included with 203 cytological samples. Average age at initial FNA was 14.7 years (range 6.9-18.6 years). The numbers of nodules reported for Bethesda categories I-VI were 29, 106, 22, 14, 6 and 26, respectively, and the rate of malignancy was: 13.8, 4.7, 22.7, 35.7, 83.3 and 100%, respectively. Use of ultrasound guidance reduced the non-diagnostic rate from 38.1 to 11.5%. Introduction of on-site adequacy testing further reduced the non-diagnostic rate to 6.5% since 2014. CONCLUSIONS The risk of malignancy for thyroid nodules in this pediatric cohort is higher than reported in adults. However, rates described here are much closer to adult ranges than previously published pediatric cohorts. The addition of adequacy testing improved the non-diagnostic rate of FNA procedures performed with ultrasound guidance.

Abstract
An increasing number of children are diagnosed with thyroid cancer. Most patients do not have an identifiable cause; however, tumor predisposition syndromes may be associated with development of both differentiated and medullary thyroid cancer. With an excellent prognosis for most patients, the goal of therapy is to optimize outcome and reduce complications. The increased knowledge of the oncogenic drivers provides opportunities to improve the accuracy of diagnosis, stratify surgery, and select systemic therapy that may be considered for neoadjuvant and adjuvant treatment. Treatment complications can be reduced by referral to regional, high-volume pediatric thyroid centers.

Abstract
BACKGROUND Papillary thyroid cancer (PTC) is an uncommon pediatric disease with an excellent prognosis. In follow-up surveillance, neck ultrasound (US), basal and thyroid-stimulating hormone-stimulated serum thyroglobulin (Tg) levels, and diagnostic whole-body radioactive iodine scans (DxWBS) have been traditionally used in both adults and children for the detection of recurrence or metastases of PTC. METHODS Two pediatric patients with metastatic PTC were followed after standard ablative treatment with routine neck US and serum Tg levels, as well as periodic DxWBS. RESULTS Neck US identified recurrent and metastatic PTC which DxWBS failed to detect. CONCLUSION Neck US was superior to DxWBS in the detection of recurrent PTC in these 2 pediatric patients. These findings are consistent with the 2015 American Thyroid Association (ATA) Guidelines that neck US is an ideal imaging modality in pediatric patients for the surveillance of PTC local recurrence or lymph node metastases.

Abstract
There is lack of data to predict lymph node metastases in pediatric thyroid cancer. The aims are to study (1) the factors affecting the lymph node metastases in children and adolescence with papillary thyroid carcinoma in region exposed to radiation and (2) to evaluate the predictive significance of these factors for lateral compartment lymphadenectomy. Five hundred and nine patients with papillary thyroid carcinoma underwent total thyroidectomy and lymph nodes resection (central and lateral compartments of the neck) surgery during the period of 1991-2010 in Belarus were recruited. The factors related to lymph node metastases were studied in these patients. In the patients with papillary thyroid carcinoma, increase number of cancer-positive lymph nodes in the central neck compartment were associated with a risk to develop lateral nodal disease as well as bilateral nodal disease. Futhermore, positive lateral compartment nodal metastases are associated with age and gender of the patients, tumour size, minimal extra-thyroidal extension, solid architectonic, extensive desmoplasia in carcinoma, presence of psammoma bodies, extensive involvement of the thyroid and metastatic ratio index revealed after examination of the central cervical chain lymph nodes. The presence of nodal disease, degree of lymph node involvement and the distribution of lymph node metastases significantly increase the recurrence rates of patients with papillary thyroid carcinoma. To conclude, the lymph nodes metastases in young patients with papillary thyroid carcinoma in post-Chernobyl exposed region are common and the pattern could be predicted by many clinical and pathological factors.

Abstract
BACKGROUND This study aims to analyze changes in characteristics, practice and outcomes of pediatric differentiated thyroid cancer (DTC) at our tertiary care institution. METHODS Patients <21 years of age diagnosed between 1973 and 2013 were identified. Clinicopathological data, treatment and outcomes were obtained by a retrospective review. RESULTS Thirteen males and 68 females were divided into Group A (n=35, diagnosed before July 1993) and Group B (n=46, diagnosed after July 1993). Group B was more likely to undergo neck ultrasound (US) (70% vs. 23%, p<0.0001) and fine-needle aspiration (FNA) biopsy (80% vs. 26%, p<0.0001). Patients in Group B more often underwent total thyroidectomy as a definitive surgical treatment (87% vs. 69%, p=0.04). There was no difference in radioactive iodine use. Recurrence-free survival was similar. CONCLUSIONS Increased use of US and FNA has affected initial surgical management in the latter part of the study, possibly due to extension of adult DTC guidelines. The effects of the new pediatric DTC guidelines need further study.

Abstract
BACKGROUND The 2015 American Thyroid Association (ATA) Management Guidelines for Children with Thyroid Nodules and Differentiated Thyroid Cancer provides selection criteria for nodules prior to ultrasound-guided fine-needle aspiration biopsy. OBJECTIVE To evaluate the diagnostic performance of pediatric thyroid nodule risk stratification for predicting malignancy when applying the ultrasound (US) criteria recommended. MATERIALS AND METHODS US characteristics of 39 thyroid nodules in 33 pediatric patients who underwent US fine-needle aspiration biopsy were reviewed by two radiologists. Based on the aggregated US criteria from the ATA Guidelines, each nodule was assigned a level of malignancy risk. Kappa coefficients were estimated to assess intra- and interobserver reliability. Using each patient's largest nodule observation (n = 33), univariable exact logistic regression analyses of US parameters were then conducted to estimate the odds of a malignant pathology diagnosis. A penalized Firth correction was employed in the univariable models analyzing composition, shape and level of suspicion due to quasi-complete data separation. RESULTS Twenty-seven nodules in 21 patients (median age: 16 years; 17 female) were benign and 12 nodules in 12 patients (median age: 16.5 years; 11 female) were malignant. Intraobserver agreement was substantial to almost perfect for composition, echogenicity, shape and margins. Interobserver agreement was almost perfect for composite level of suspicion. High level of suspicion was assigned to all 12 malignant nodules versus 9/21 (43%) of the benign nodules. Level of suspicion, solid/predominantly solid composition, irregular margins and echogenic foci emerged as significant predictors of malignancy with odds ratios (OR) of 8.5 (95% confidence interval [CI]: 1.7-1,130, P = 0.001), 10.5 (95% CI: 1.1-1,417, P = 0.04), 53.2 (95% CI: 5.1-2,988, P < 0.0001) and 3.5 (95% CI: 1.1-23.2, P = 0.03), respectively. CONCLUSION The composite, US-based risk stratification criteria from the 2015 ATA Guidelines may provide an appropriate and reproducible method for estimating risk of malignancy for pediatric thyroid nodules.

Abstract
First introduced in 1946, radioactive iodine (I-131) produces short-range beta radiation with a half-life of 8 days. The physical properties of I-131 combined with the high degree of uptake in the differentiated thyroid cancers (DTCs) led to the use of I-131 as a therapeutic agent for DTC in adults. There are two indications for the potential use of I-131 therapy in pediatric thyroid disorders: nonsurgical treatment of hyperthyroidism owing to Graves' disease and the treatment of children with intermediate- and high-risk DTC. However, children are not just miniature adults. Not only are children and the pediatric thyroid gland more sensitive to radiation than adults but also the biologic behavior of DTC differs between children and adults as well. As opposed to adults, children with DTC typically present with advanced disease at diagnosis; yet, they respond rapidly to therapy and have an excellent prognosis that is significantly better than that in adult counterparts with advanced disease. Unfortunately, there are also higher rates of local and distant disease recurrence in children with DTC compared with adults, mandating lifelong surveillance. Further, children have a longer life expectancy during which the adverse effects of I-131 therapy may become manifest. Recognizing the differences between adults and children with DTC, the American Thyroid Association commissioned a task force of experts who developed and recently published a guideline to address the unique issues related to the management of thyroid nodules and DTC in children. This article reviews the epidemiology, diagnosis, staging, treatment, therapy-related effects, and suggestions for surveillance in children with DTC, focusing not only on the differences between adults and children with this disease but also on the latest recommendations from the inaugural pediatric management guidelines of the American Thyroid Association.

Abstract
OBJECTIVE Pediatric differentiated thyroid cancer (DTC) frequently presents with extensive disease. We studied the value of pre-ablation thyroglobulin (Tg) and Tg normalized to thyroid-stimulating hormone (TSH) levels in predicting distant metastases in pediatric patients with DTC. METHODS This is a retrospective cohort study of patients <21 years old who underwent thyroidectomy followed by 131I ablation for DTC at 3 university hospitals over 20 years. Tg levels and the Tg/TSH ratio following surgery but prior to 131I ablation were assessed. The presence of distant metastatic disease was determined from the postablation whole-body scan. RESULTS We studied 44 patients with a mean age of 15.2 years (range 7 to 21 years) and mean tumor size of 2.8 cm. Eight patients had distant metastases and had a higher mean pre-ablation Tg value compared to patients without distant metastases (1,037 μg/L versus 93.5 μg/L, P<.01). The pre-ablation Tg/TSH ratio was also associated with the presence of distant metastases: 12.5 ± 18.8 μg/mU in patients with distant metastases versus 0.7 ± 1.8 μg/mU in patients without (P<.01). A nomogram to predict distant metastases yielded areas under the receiver operating characteristic curve of 0.85 for Tg and 0.83 for Tg/TSH ratio. CONCLUSION After initial thyroidectomy, elevated preablation Tg and Tg/TSH ratio are associated with distant metastatic disease in pediatric DTC. This may inform the decision to ablate with 131I, as well as the dosage. ABBREVIATIONS ATA = American Thyroid Association CI = confidence interval DTC = differentiated thyroid cancer OR = odds ratio ROC = receiver operating characteristic Tg = thyroglobulin.

Abstract
PURPOSE External radiation to the head and neck can lead to an increased incidence of thyroid nodules. We investigated whether patients requiring repeated head and neck imaging for the management of shunted hydrocephalus had a higher incidence of ultrasound-detected thyroid nodules compared to reports of comparable age. METHODS Patients treated at our institution for shunted hydrocephalus from 1990 to 2003 were contacted. Enroled patients underwent a thyroid ultrasound. Demographic data and radiation exposure history were obtained retrospectively. RESULTS Thyroid nodules were identified sonographically in 15/112 patients (13.6 %). Patients with thyroid nodules were older (mean 24.3 ± 7.6 years) than those without (mean 18.4 ± 8.0 years) (p = 0.005). Those with a detectable thyroid nodule had a longer follow up time compared to those who did not (mean 21.9 ± 5.5 vs. 15.1 ± 7 years, respectively) (p = 0.018). CONCLUSION Patients with shunted hydrocephalus are exposed to substantial head and neck radiation from diagnostic imaging and have a higher incidence of thyroid nodules detected by ultrasonography. These patients should be provided ongoing surveillance for detection of thyroid nodules and the possibility of malignancy.

Abstract
Well differentiated thyroid cancer (DTC) in children is characterized by a high rate of response to treatment and low disease-specific mortality. Treatment of children with DTC has evolved toward a greater reliance on evaluation and monitoring with serial serum thyroglobulin measurements and ultrasound examinations. Radioiodine therapy is recommended for thyroid remnant ablation in high-risk patients, treatment of demonstrated radioiodine-avid local-regional disease not amenable to surgical resection, or distant radioiodine-avid metastatic disease. Sufficient time should be given for benefits of radioiodine therapy to be realized, with follow-up monitoring. Re-treatment with radioiodine can be deferred until progression of significant disease manifests.

Abstract
BACKGROUND The aim of this study was to analyze the clinical features and clinical outcomes of papillary thyroid carcinoma (PTC) in the pediatric and adolescent population treated in our institution. METHODS The subjects were 227 PTC patients 20 years of age or under treated initially between 1979 and 2012. Their mean age at diagnosis was 18-year old (range 7-20 years). Patient characteristics and outcomes in the period before 1999 and the period after 2000 were compared. Cause-specific survival (CSS) rates and disease-free survival (DFS) rates were calculated by the Kaplan-Meier method. RESULTS Two patients died of their disease and 45 patients had recurrent disease (36 in lymph node, seven in a remnant thyroid, and 11 in the form of distant metastasis). The 10-, 20-, and 30-CSS rates were 99.3, 99.3, and 96.5%, respectively, and the 10-, 20-, and 30-DFS were 83.6, 70.7, and 64.0%, respectively. Gender and preoperative lymph node metastasis were identified as significant factors related to DFS in the multivariate analysis. After the year 2000, there were significantly more patients with a small primary tumor size, significantly more patients without distant metastasis at presentation and significantly more patients without extrathyroidal invasion. CONCLUSION The number of patients with advanced cancer has been declining in recent years. Lobectomy with prophylactic unilateral central neck dissection is considered acceptable for patients without the risk factors for recurrence.

Abstract
The influence of predictors for recurrence in relation to recurrence-free survival was analyzed retrospectively in differentiated thyroid cancer (DTC) patients under 21 years of age who underwent primary surgical treatment and who had a pathological diagnosis of DTC between 1983 and 2012 at Fudan University Cancer Hospital. Recurrences were retrospectively analyzed using a Cox regression model for the hazard ratio (HR) according to the clinicopathological features. A meta-analysis was performed with respect to the potential predictors for recurrence from current related studies. In the present study, there were 146 young patients aged from 7 to 20 years, with a female/male ratio of 2.65/1. Female gender was the only factor significantly associated with recurrence according to univariate (HR = 2.812, P = 0.037) and multivariate (HR = 4.107, P = 0.024) Cox regression analyses. Meta-analyses revealed that multifocality (HR = 1.91, P < 0.05) and presentation at diagnosis (HR = 1.39, P < 0.05) were highly associated with recurrence in young DTC patients. However, female gender and other factors, such as age (≤10 vs. 11-20 years), PTC (PTC vs. FTC), extrathyroidal extension, lymph node metastasis, total thyroidectomy (total vs. less than total), radioiodine therapy, and radiation history, were not associated with recurrence in young DTC patients. In conclusion, multifocality and presentation at diagnosis are strong predictive factors of recurrence in relation to recurrence-free survival. We recommend studies with larger sample sizes and longer follow-up to verify the influence of predictors for disease recurrence in young patients.

Abstract
BACKGROUND Previous guidelines for the management of thyroid nodules and cancers were geared toward adults. Compared with thyroid neoplasms in adults, however, those in the pediatric population exhibit differences in pathophysiology, clinical presentation, and long-term outcomes. Furthermore, therapy that may be recommended for an adult may not be appropriate for a child who is at low risk for death but at higher risk for long-term harm from overly aggressive treatment. For these reasons, unique guidelines for children and adolescents with thyroid tumors are needed. METHODS A task force commissioned by the American Thyroid Association (ATA) developed a series of clinically relevant questions pertaining to the management of children with thyroid nodules and differentiated thyroid cancer (DTC). Using an extensive literature search, primarily focused on studies that included subjects ≤18 years of age, the task force identified and reviewed relevant articles through April 2014. Recommendations were made based upon scientific evidence and expert opinion and were graded using a modified schema from the United States Preventive Services Task Force. RESULTS These inaugural guidelines provide recommendations for the evaluation and management of thyroid nodules in children and adolescents, including the role and interpretation of ultrasound, fine-needle aspiration cytology, and the management of benign nodules. Recommendations for the evaluation, treatment, and follow-up of children and adolescents with DTC are outlined and include preoperative staging, surgical management, postoperative staging, the role of radioactive iodine therapy, and goals for thyrotropin suppression. Management algorithms are proposed and separate recommendations for papillary and follicular thyroid cancers are provided. CONCLUSIONS In response to our charge as an independent task force appointed by the ATA, we developed recommendations based on scientific evidence and expert opinion for the management of thyroid nodules and DTC in children and adolescents. In our opinion, these represent the current optimal care for children and adolescents with these conditions.

Abstract
BACKGROUND Thyroid nodules are less common in children than adults, but the risk of malignancy in thyroid nodules is much higher in children. The ability to characterize pediatric thyroid nodules has improved with the use of ultrasound-guided fine-needle aspiration, the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) classification system, and expanded molecular testing. Nevertheless, stratification criteria to predict thyroid malignancy in children are poorly defined. Our objective was to determine if clinical presentation and molecular genetics could predict malignancy in pediatric thyroid nodules. METHODS Retrospective chart review of patients ≤18 years of age at the Children's Hospital of Pittsburgh of the University of Pittsburgh Medical Center with the diagnosis of a thyroid nodule from January 2007 to January 2012 was conducted. Eighty-nine subjects fulfilled the inclusion criteria: 1) thyroid nodule ≥0.8 cm and biopsy (n=76), or 2) thyroid nodule ≥0.8 cm, no biopsy, and ultrasound follow-up for at least 2 years (n=13). RESULTS Twenty-four (27%) of 89 patients were diagnosed with thyroid cancer (50% papillary thyroid carcinoma [PTC], 50% follicular variant of papillary thyroid carcinoma [FVPTC]). Features associated with malignancy included larger nodule size, palpable nodule, or palpable lymphadenopathy. There were no differences in presenting features between patients with PTC and those with FVPTC. Thyroid malignancy was diagnosed in all nine patients with a molecular abnormality (BRAF, RAS, RET/PTC, PAX8/PPARγ). CONCLUSIONS Clinical features, FNA cytology, and molecular genetics are valuable tools to discriminate benign from malignant nodules in pediatric patients. This information is important to direct subsequent clinical management.

Abstract
Thyroid nodules are commonly diagnosed in adults. Although rare in children, the risk for thyroid cancer is much higher in the pediatric population compared with adults. Presenting as either a solitary nodule or a multinodular goiter, thyroid nodular disease in children requires a thorough workup that includes a detailed clinical examination comprised of prior history of thyroid disease in the patient or in their family, history of radiation exposure, careful palpation of the thyroid and lymph nodes, blood tests, ultrasonography, and cytological assessment. Thyroid surgery is the gold-standard treatment for pediatric thyroid nodules; nonetheless, the extent of surgery remains controversial. Because surgery is not without risk, the decision matrix necessitates focus on the benefits of surgery for the child contingent upon all the preoperative exams. New diagnostic technology such as molecular testing with fine needle aspiration biopsy may help distinguish between benign and malignant lesions while potentially decreasing surgery for benign disease. The objective of this review is to summarize new concepts in clinical disease management of nodular thyroid disease in the pediatric population, including patient history, medical examination, and diagnosis workup.

Abstract
According to the literature, thyroid nodules (TNs) are quite rare in the first two decades of life and are predominantly non-cancerous, although cancerous TNs are more common in the first two decades of life than in adults. Therefore, it is important for clinicians to distinguish benign from malignant lesions preoperatively because the latter require a total thyroidectomy with or without neck lymph node dissection. A careful work-up and a fine-needle aspiration biopsy (FNAB) are mandatory to improve the preoperative diagnosis. High-resolution thyroid ultrasound and real-time elastosonography are adjuvant presurgical tools in selecting patients for surgery, particularly those with indeterminate or non-diagnostic cytology. Elevated thyroid-stimulating hormone (TSH) level in a patient with a thyroid nodule is a new laboratory predictor of thyroid cancer risk. The majority of thyroid carcinomas derive from the follicular cell, whereas medullary thyroid carcinoma (MTC) derives from calcitonin-producing cells. Patients with MTC are screened for germ-line RET mutations to detect carriers and identify family members for prophylactic or therapeutic thyroidectomy.

Abstract
BACKGROUND AND AIMS Paediatric thyroid cancer is a rare disease, making diagnosis and treatment particularly challenging. Here we present the Scottish experience of thyroid cancer in the paediatric population and give an overview of how a child or adolescent that presents with a thyroid nodule should be investigated and managed. METHODS AND RESULTS Data has been obtained from ISD Scotland, giving population-based information on paediatric thyroid cancer. A literature review has been performed on the management and treatment of thyroid cancer in the younger population. Paediatric thyroid cancer in Scotland is a rare disease, although the incidence is increasing each year. In general, differentiated paediatric thyroid cancer carries a good prognosis, while the results are more mixed in the rarer pathologies such as medullary cancer. CONCLUSION Due to the small numbers of patients diagnosed each year in Scotland, it is imperative that these patients are discussed at a multidisciplinary thyroid MDT and managed in a tertiary referral centre by consultants and medical/nursing support staff who have experience in treating these patients.

Abstract
PURPOSE Our institution routinely utilizes needle core biopsy (NCB), instead of fine needle aspiration, in the evaluation of pediatric thyroid nodules. This practice initially arose from limited cytopathology services in our hospital. Given the lack of information regarding the utility of NCB in diagnosing pediatric thyroid neoplasms, we set out to review our institution's experience with this technique. METHODS We performed a single institution retrospective chart review of all children who underwent thyroidectomy for primary thyroid pathology. RESULTS Seventy-four patients, with a mean age of 12.9 ± 4.5 (SD) years, underwent partial or total thyroidectomy between 2002 and 2010. Seven of these patients had medically refractive hyperthyroidism. The remaining 67 patients had one or more thyroid nodules as identified by ultrasound. 24 (36 %) of these cases were malignant on final pathology. 14 (58 %) of the malignant cases were papillary thyroid carcinoma. 46 of the thyroid nodule cases underwent pre-operative NCB. Biopsy results for these patients were non-diagnostic in 6 (13 %), benign in 11 (24 %), atypical in 17 (37 %), and malignant in 12 (26 %). There were no complications arising from NCB. Sensitivity of NCB for diagnosing papillary carcinoma (PC) and follicular neoplasm was calculated at 0.88 (0.47-1.0, 95 % CI) and 0.84 (0.60-0.97, 95 % CI), respectively. Of the 28 patients not undergoing preoperative NCB, 12 underwent hemithyroidectomy, with one patient (8 %) requiring completion thyroidectomy for PC. Overall, the sensitivity of NCB in diagnosing PC and follicular thyroid neoplasms was 0.85 (0.55-0.99, 95 % CI), while the specificity was 0.63 (0.42-0.82, 95 % CI). CONCLUSIONS Needle core biopsy appears to have a low rate of associated complications, and its sensitivity for diagnosing PC and follicular neoplasm is comparable to what has been reported for fine needle aspiration biopsy in a similar patient population.

Abstract
Thyroid nodules are less frequent in childhood than in adulthood, but are more often malignant. Recent estimates suggest that up to 25% of thyroid nodules in children are malignant, therefore, a more aggressive approach is recommended. In this review, we suggest an approach based on a first-step clinical, laboratory, and sonographic evaluation. A history of irradiation of the neck, cranium or upper thorax, previous thyroid diseases or thyroid neoplasms in the family should alert clinicians as being associated with a greater likelihood of malignant nodules. Signs or symptoms of hyperthyroidism and dysmorphic features should be carefully considered during the physical examination. Palpable firm lymph nodes, found in some 70% of cases, are the most significant clinical finding in children with malignant nodules. Although the routine determination of calcitonin levels is not uniformly practiced, it can help recognize sporadic or familial medullary thyroid neoplasms. Blood thyroid stimulating hormone, free thyroxine, and free triiodothyronine determinations (the latter in case of symptoms of hyperthyroidism) are aimed at identifying the few hyperthyroid patients, for whom the next step should be scintiscan. Hyperthyroid patients usually disclose an increased uptake, and a diagnosis of toxic adenoma is commonly made. Cases with normal thyroid function or hypothyroidism (which is usually subclinical) should be evaluated by fine-needle aspiration biopsy (FNAB). In eu/hypo-thyroid patients, scintiscan provides poor diagnostic information and should not be routinely employed. Thyroid ultrasonography is used to select cases for FNAB. Although ultrasound cannot reliably discriminate between benign and malignant lesions, it does provide an index of suspicion. Sonographic features that increase the likelihood of malignancy are microcalcifications, lymph node alterations, nodule growth under levothyroxine treatment, and increased intranodular vascularization demonstrated by color Doppler. There is growing evidence that elastography may provide further information on nodule characteristics. FNAB is indicated in all cases with a likelihood of malignancy. FNAB has a diagnostic accuracy of approximately 90% and is used in selection of patients which require surgery. Recently, histological markers and elastography have been introduced to increase the specificity of FNAB and ultrasound, respectively. The pitfall in FNAB cytology is the follicular cytology, in which it is not possible to distinguish between adenoma and carcinoma and therefore thyroidectomy is advised.

Abstract
Based on strong research evidence, thyroid nodules in children and teenagers are more likely to be malignant than in adults. Based on strong research evidence, a history of ionizing radiation to the head or neck is an independent risk factor for the development of thyroid malignancies. There is strong research evidence, including a recent meta-analysis, supporting the use of fine-needle aspiration biopsy in the evaluation of all pediatric and adolescent patients presenting with a thyroid nodule. The surgical management and postoperative care of pediatric and adolescent patients who have well-differentiated thyroid carcinomas remains controversial, because the rarity of the disease limits the ability to conduct randomized, prospective research studies. Numerous studies have demonstrated that, despite presenting with more advanced disease, pediatric and adolescent patients with thyroid carcinoma have a higher survival rate than adults. The American Thyroid Association has issued strong evidence-based recommendations for the management of medullary thyroid carcinoma, including RET mutation testing and early prophylactic total thyroidectomy in children with high-risk mutations.

Abstract
PURPOSE The aim of this study was to determine the role of thyrotropin receptor messenger RNA as a novel blood test for evaluation of thyroid nodules and cancer in children. METHODS We reviewed thyroid disease management of patients younger than 18 years with thyrotropin receptor messenger RNA measurements identified from a prospective, institutional review board-approved registry during 2008 to 2010. RESULTS Thirty-nine thyrotropin receptor messenger RNA measurements were made in 21 female patients (12-17 years old; median, 16 years). Four patients with fine-needle aspiration only had benign thyroid cytology, and 3 of 4 had undetectable thyrotropin receptor messenger RNA. Seventeen patients underwent 22 thyroid operations. Preoperative thyrotropin receptor messenger RNA was measured in 9 patients: 3 of 4 with thyroid cancer had elevated levels and 3 of 5 with goiters undetectable. Postthyroidectomy surveillance (median, 16 months; range, 6-24) of 11 thyroid cancer patients (8 papillary, 3 follicular) showed that thyrotropin receptor messenger RNA was concordant with thyroglobulin in 14 (73%) of 19 measurements. In 3 (16%) of 19 measurements, thyrotropin receptor messenger RNA was the only blood test useful for disease assessment because of elevated antithyroglobulin antibodies. Overall, to predict thyroid cancer, thyrotropin receptor messenger RNA demonstrated 73% sensitivity, 82% specificity, 62% positive predictive value, 88% negative predictive value, and 79% accuracy. CONCLUSION Thyrotropin receptor messenger RNA provides complementary evaluation to thyroglobulin and fine-needle aspiration for pediatric thyroid nodule management.

Abstract
A substantial proportion of childhood cancers are attributable to an underlying genetic syndrome or inherited susceptibility. Recognition of affected children allows for appropriate cancer risk assessment, genetic counseling, and testing. Identification of individuals who are at increased risk to develop cancers during childhood can guide cancer surveillance and clinical management, which may improve outcomes for both the patient and other at-risk relatives. The information provided through this article will focus on the current complexities involved in the evaluation and management of children with cancer-predisposing genetic conditions and highlight remaining questions for discussion.

Abstract
Pediatric thyroid cancer is a rare disease with an excellent prognosis. Compared with adults, epithelial-derived differentiated thyroid cancer (DTC), which includes papillary and follicular thyroid cancer, presents at more advanced stages in children and is associated with higher rates of recurrence. Because of its uncommon occurrence, randomized trials have not been applied to test best-care options in children. Even in adults that have a 10-fold or higher incidence of thyroid cancer than children, few prospective trials have been executed to compare treatment approaches. We recognize that treatment recommendations have changed over the past few decades and will continue to do so. Respecting the aggressiveness of pediatric thyroid cancer, high recurrence rates, and the problems associated with decades of long-term follow-up, a premium should be placed on treatments that minimize risk of recurrence and the adverse effects of treatments and facilitate follow-up. We recommend that total thyroidectomy and central compartment lymph node dissection is the surgical procedure of choice for children with DTC if it can be performed by a high-volume thyroid surgeon. We recommend radioactive iodine therapy for remnant ablation or residual disease for most children with DTC. We recommend long-term follow-up because disease can recur decades after initial diagnosis and therapy. Considering the complexity of DTC management and the potential complications associated with therapy, it is essential that pediatric DTC be managed by physicians with expertise in this area.

Abstract
Thyroid cancer in children and adolescents is usually a major concern for physicians, patients, and parents. Controversies regarding the aggressiveness of the clinical presentation and the ideal therapeutic approach remain among the scientific community. The current recommendations and staging systems are based on data generated by studies in adults, and this might lead to overtreating in some cases as well as undertreating in others. Understanding the differences in the biology, clinical course, and outcomes in this population is crucial for therapeutic decisions. This paper evaluates the biology, clinical presentation, recurrences, and overall survival as well as the staging systems in children and adolescents with differentiated thyroid cancer.

Abstract
BACKGROUND AND PURPOSE Papillary thyroid carcinoma has a favorable outcome in children. Recent experience with young children cases with early recurrences, after the total thyroidectomy and excision of palpable lymph nodes, in contrast to usual course of disease in adolescent cases, prompted us to review our experience on papillary carcinoma surgery. MATERIALS AND METHODS Sixteen children who underwent surgery for papillary carcinoma between 1997 and 2010 were included. The charts and surgery notes were evaluated retrospectively and age, sex, complaints and physical findings at presentation, past medical history, results of laboratory tests, imaging findings, aspiration biopsy, extent of disease, details of surgery, complications and postoperative course were noted. RESULTS Male to female ratio was 3:1. The mean age was 10.9 years (range, 5-16). The presenting symptom was palpable swelling in the neck (n = 12) or asymptomatic nodule was detected incidentally (n = 4). Physical examination findings were palpable nodule (n = 7), lymphadenopathy (n = 6) or both (n = 4). Thyroid ultrasound (US) revealed nodule (n = 9), heterogenisity of the parenchyma and enlargement of thyroid (n = 9), and microcalcifications (n = 5). Fine-needle aspiration biopsy was performed in 12 patients and was suggestive for malignancy in most cases (91%). Pulmonary metastasis was detected at presentation in two patients and appeared after thyroidectomy in one patient. Complementary thyroidectomy was performed in nine patients because the total thyroidectomy with or without cervical lymph node dissection was the treatment of choice (n = 15). Iodine scan was performed 4 weeks later following thyroidectomy. Radioactive iodine ablation (RIA) therapy was given to 11 patients who had residual or recurrent disease. Postoperative complications were permanent hypoparathyroidism (n = 4), recurrent laryngeal nerve injury (n = 3), lymphorea (n = 1) and Horner's syndrome (n = 1). CONCLUSION Total thyroidectomy and excision of affected lymph nodes is the current mode of surgical management for thyroid papillary carcinoma in children. However, especially in young children (<10 years), modified lymph node dissection should be added to total thyroidectomy in order to avoid leaving the residual tumor foci which can impair the efficacy of the ablation therapy.

Abstract
Children with differentiated thyroid cancer (DTC) often present with extensive disease that inclined clinicians in prior decades toward aggressive treatment including total thyroidectomy, radical neck dissection and universal prescription of radioactive iodine (RAI). Recent series with 40 years of follow-up have shown that fewer than 2% of children ultimately die from DTC, but they may have increased all-cause mortality from second malignancies that might be related to previous radiation exposure. In this article, we review data to support the notion that an individualized, risk-stratified approach to therapy should be used for children with DTC. Ideally this will provide aggressive therapy for those in whom aggressive treatment is warranted, but withhold aggressive and risk-associated therapy from those who are not likely to benefit.

Abstract
BACKGROUND The optimal dose and efficacy of ¹³¹I treatment of children and adolescents with well-differentiated thyroid carcinoma (WDTC) and pulmonary metastases are not well established. A therapeutic challenge is to achieve the maximum benefit of ¹³¹I to decrease disease-related morbidity and obtain disease-free survival while avoiding the potential complications of ¹³¹I therapy. SUMMARY We systematically reviewed the published literature on children and adolescents with WDTC and pulmonary metastases treated with ¹³¹I to examine outcomes after ¹³¹I administration and the risks and benefits of therapy. After reviewing 14 published articles, 9 articles met our inclusion criteria encompassing 112 pediatric and adolescent patients with WDTC and pulmonary metastases 21 years of age or younger at diagnosis spanning a follow-up period of 0.6–45 years. ¹³¹I therapy after surgery and thyrotropin suppression resulted in complete, partial, and no disease response in 47.32%, 38.39%, and 14.29% of patients, respectively. Five studies provided data on disease response in relation to ¹³¹I dose. In general, nonresponders received the highest ¹³¹I doses and complete responders received a higher dose than partial responders. The disease-specific mortality rate was 2.68%. Survival was 97.32%. A second primary malignancy occurred in one patient. One out of 11 patients studied experienced radiation fibrosis. CONCLUSIONS This review confirms that the majority of pediatric and adolescent patients with WDTC and pulmonary metastases treated with ¹³¹I do not achieve complete response to therapy, yet disease-specific morbidity and mortality appear to remain low. It is therefore prudent to use caution in the repeated administration of ¹³¹I to such patients to ensure that adverse effects of therapy do not cause more harm than good in a disease that has an overall favorable natural course. Long-term prospective studies are needed to analyze disease-specific morbidity and mortality, recurrence rate, dose-specific response, and dose-related adverse effects of ¹³¹I in this patient population.

Abstract
BACKGROUND Whereas thyroid nodules are less common among children than among adults, the anxiety generated by the finding of a thyroid nodule is high because 20% of nodules found in children contain thyroid cancer. Discovery of a nodule in the context of hyperthyroidism is usually comforting due to the presumption that the nodule represents a benign toxic adenoma. SUMMARY An 11-year-old girl presented with heavy menses, fatigue, and a right thyroid mass. Laboratory evaluation revealed elevated triiodothyronine and undetectable thyroid-stimulating hormone. Thyroid ultrasonography revealed a 3.5 cm nonhomogenous nodule, and scintigraphy was consistent with an autonomous hyper-functioning nodule. Fine-needle aspiration biopsy could not rule out malignancy, and patient underwent right hemithyroidectomy and isthmusectomy. Pathology was consistent with papillary thyroid carcinoma. CONCLUSIONS We report the discovery of papillary thyroid carcinoma in an autonomously hyperfunctioning nodule in an 11-year-old girl. Detection of an autonomously functioning thyroid nodule in children and adolescents does not exclude the possibility of thyroid carcinoma and warrants careful evaluation and appropriate therapy.

Thyroid fine needle aspiration biopsies in children: study of cytological-histological correlation and immunostaining with thyroid peroxidase monoclonal antibodies. INTERNATIONAL JOURNAL OF PEDIATRIC ENDOCRINOLOGY 2010; 2010:690108.

Abstract
Context. There is limited data comparing results of fine needle aspiration biopsies (FNABs) to histological diagnosis in children.
Design. FNABs were performed in 707 children and cytological results were compared to histology in 165 cases. The usefulness of immunostaining with anti-TPO monoclonal antibodies (MoAb47) on FNAB samples was examined in 54 operated patients.
Results. Among unsatisfactory, benign, suspicious, and malignant FNAB, the histological diagnoses were benign in 12/12 (100%), 69/70 (98.5%), 40/50 (80.0%), and 0/33 (0%), respectively. After surgery, malignancy was established in 44/165 (26.6%) cases. The sensitivity, specificity, and positive and negative predictive values were 95.4%, 55.8%, 61.7%, and 95% with standard FNAB; and 100%, 75%, 73.3, and 100% with MoAb47. Among suspicious FNAB, positive MoAb47 staining was a reliable marker for exclusion of malignancy.
Conclusion. Benign and malignant FNAB accurately predict histological diagnosis. In suspicious FNAB, MoAb47 immunostaining may be a useful adjunct to standard cytology.

Abstract
OBJECTIVE To evaluate the clinical characteristics, course, and outcome of differentiated thyroid carcinoma (DTC) in pre-pubertal children compared with adolescents. STUDY DESIGN The records of 10 pre-pubertal and 17 pubertal patients in whom DTC was diagnosed and who were observed in our tertiary pediatric endocrine clinic were reviewed. Extension of tumor at presentation, treatment modality, course, and outcome were analyzed. RESULTS A positive family history of DTC was more prevalent in the pre-pubertal group (P = .037). At diagnosis, they had a greater degree of extrathyroid extension (P = .012), lymph node involvement (P = .009), and lung metastases (P = .009). The extent of surgery was similar in both groups, whereas the weight-adjusted radioiodine (I(131)) ablative dose was higher in the pre-pubertal group (P = .004). During the median follow-up of 5 years, the overall survival rate was 100% for both groups, with no significant difference in evidence of residual tumor after initial therapy or the recurrence rate. CONCLUSION DTC has a more aggressive presentation in pre-pubertal children. Rigorous initial surgical and I(131) treatment, followed by thyrotropin suppression, was found to result in an outcome similar to that achieved in the pubertal group.

Abstract
This article presents an overview of medical management of persistent or recurrent differentiated thyroid cancer, in particular focusing on monitoring strategy and treatment plans. Most patients with differentiated thyroid carcinoma can be successfully rendered to be free of disease with initial treatments, and those with persistent or recurrent disease can still expect long-term survival when they are monitored properly and treated accordingly. Along with serum thyroglobulin, neck ultrasonography, and radioactive iodine whole-body scans, the use of cross-sectional imaging studies and (18F) fluoro-2-deoxy-D-glucose-positron emission tomography have facilitated the effort in localizing lesions and traditional treatments can be implemented effectively. For disease resistant to conventional therapies, there are new treatment modalities emerging and being tested, including several agents targeting specific signaling pathways, each of which may offer the potential remedy.

Abstract
PURPOSE OF REVIEW Differentiated thyroid cancer is the most common endocrine malignancy in children. In 2006, the American Thyroid Association Guidelines Taskforce released detailed management recommendations for differentiated thyroid cancer, which primarily addressed the approach for treating adult patients. Children with differentiated thyroid cancer present with more advanced disease and yet have a more favorable outcome than adults. Thus optimal treatment for younger patients with differentiated thyroid cancer may differ from that for adults. RECENT FINDINGS All available data regarding differentiated thyroid cancer treatment in children are retrospective. In the past year, several large case series have been published that strengthen the argument for total thyroidectomy at the time of diagnosis, followed by administration of radioactive iodine for remnant ablation. There have also been recent advances in understanding the genetic abnormalities associated with pediatric thyroid cancer. SUMMARY The optimal treatment of differentiated thyroid cancer in pediatric patients continues to be debated. Recent publications from institutions around the world provide useful data regarding current approaches to this unusual disease. Further collaborative studies are needed to further refine the surgical approach, particularly the extent of lymph-node dissection, radioactive iodine dosing, and the role of genetic analysis in diagnosis and clinical approach.
