Abstract
PURPOSE To summarize the treatment experience of single-center children with PTC and to explore the influence of initial surgery on the recurrence/metastasis of papillary thyroid carcinoma (PTC) in children. METHODS A retrospective analysis of PTC case data of children (≤ 18 years old) who were admitted to and received surgical treatment in the First Affiliated Hospital of Kunming Medical University from January 2012 to December 2020. RESULTS A total of 64 children with PTC were included, including 45 cases (70.31%) with a single lesion, and 19 cases (29.69%) with multiple lesions (≥ 2 lesions). Fifteen patients relapsed. Univariate analysis found that gender, thyroidectomy scope, central lymph node dissection, and lateral lymph node dissection were risk factors affecting reoperation; multi-factor analysis showed that central lymph node dissection was an independent risk factor affecting reoperation. According to Kaplan-Meier analysis, central lymph node dissection, total thyroidectomy (TT), lobectomy (LT), and disease-free survival (DFS) were statistically significant (p = 0.000, p = 0.000). CONCLUSION At the time of diagnosis of PTC in children, the rate of lymph node metastasis in the central and lateral cervical regions is high. The vast majority of children with PTC should be treated with TT, and LT is chosen for a small number of patients. CND should be routinely lined.

Surgical treatment of pediatric and adolescent papillary thyroid cancer: a retrospective study of 54 patients in a single center. J Pediatr (Rio J) 2022; 98:425-430. [PMID: 35139341 PMCID: PMC9432047 DOI: 10.1016/j.jped.2021.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2021] [Revised: 11/20/2021] [Accepted: 11/22/2021] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVE In 2015, American Thyroid Association (ATA) issued the first version of Management Guidelines for Children with Thyroid Nodules and Differentiated Thyroid Cancer. The purpose of this study is to evaluate whether the ATA pediatric guidelines recommended surgical approach for the patient can be applied to surgical treatment of pediatric PTC in China. METHOD From April 2012 to December 2020, clinical data of children (≤18 years) with PTC consecutively admitted and treated with initial surgery in the study's department were retrospectively reviewed. RESULTS The authors found that the central lymph node metastasis (CLNM) rate was significantly higher than that in the lateral neck (83.33 % vs 62.96%, χ2 = 5.704, p = 0.017) .The lymph node metastasis rate was significantly lower in cN1b (-) patients than in cN1b (+) patient (55.00% vs 100.00%, χ2 = 15.263, p = 0.000); Meanwhile, the CLNM and LLNM rates of ipsilateral were significantly higher than those of contralateral central compartment (83.33༅vs 57.41༅%, χ2 = 8.704, p = 0.003). Lymph nodes of 51 lateral lymph node dissection (LND) were analyzed, which revealed the LNM rate of cN1b (-) patients was significantly lower than that of cN1b (+) patients (55.00% vs. 100.00%, χ2 = 15.263, p = 0.000). CONCLUSION Children and adolescents have a higher rate of lymph node metastasis at the time of diagnosis. TT should be conducted in the majority of children with PTC. CND should be routinely performed; therapeutic LND is recommended for children with cN1b (+).

Abstract
INTRODUCTION Our aim was to determine the accuracy of lymph node yield (LNY) for pediatric patients undergoing thyroidectomy with concurrent lymph nodes harvest for clinically node-negative (cN0) papillary thyroid cancer (PTC). METHODS Patients aged ≤ 18 years with cN0 PTC undergoing thyroidectomy were reviewed in the NCDB, 1998-2016. Demographic and clinical characteristics of patients with ≥ 1 LNY were compared to those without. A truncated beta-binomial distribution estimated the number of lymph nodes needed to detect pathologic nodal positivity, and LNY was calibrated for 90% sensitivity in nodal staging and stratified across clinical tumor size staging (T). RESULTS 1,948 children with cN0 PTC underwent surgical resection; median age was 17 years; 83.2% were female; 47.6% were T1, 25.3% T2, 9.3% T3. 1,272 (65.3%) of these patients had lymph nodes resected, or ≥ 1 LNY. The median LNY was 5 nodes (interquartile range 2-12); 45.9% of patients had ≥ 1 metastatic lymph nodes. In the overall ≥ 1 LNY cohort, 12 nodes (CI 9-19) were needed to predict nodal positivity with > 90% sensitivity. Based on clinical T-stage, detecting a metastatic lymph node with > 90% sensitivity required a LNY of 14 for T1; 8 for T2; 6 for T3. CONCLUSION This is the first study estimating the necessary LNY for determining nodal positivity in children with cN0 PTC. The high LNY required in small T1 tumors is likely infeasible and should not be pursued. Accuracy increases with lower LNYs for higher T-stages. Our findings can help guide prognosis and treatment for pediatric patients with PTC.

Abstract
Purpose Papillary thyroid carcinoma (PTC) in children and adolescents is prone to lateral lymph node metastasis (LNM), which is a high-risk factor for recurrence. However, few studies focused on identifying risk factors and establishing prediction models for lateral LNM of PTC in children and adolescents. Patients and Methods We retrospectively reviewed consecutive cases of children and adolescents with PTC undergoing thyroidectomy and cervical lymph node dissection between January 2009 and December 2019. The demographics and clinicopathologic features were collected and analyzed. Results A total of 102 children and adolescents with PTC were enrolled in our study; 51 of whom had lateral LNM (50%). After adjusting for other risk factors, the independent risk factors for lateral LNM were multifocality (odds ratio [OR]: 6.04; 95% confidence interval [CI]: 1.653–22.092; p=0.007), tumor size (OR: 1.752; 95% CI: 1.043–2.945; p=0.034), and the number of central LNM (OR: 1.23; 95% CI: 1.028–1.472; p=0.023). The formula of the combined predictor is: Multifocality + 0.31 × Tumor size + 0.115 × Number of central LNM. The area under the receiver operating characteristic curve of multifocality, tumor size, number of central LNM, and the combined predictor was 0.706, 0.762, 0.748, and 0.855, respectively. When the value of the combined predictor was ≥2.2744, lateral LNM could be predicted. The sensitivity and specificity of the predicted value were 82.4% and 74.5%, respectively. Conclusion The independent risk factors for lateral LNM in children and adolescents with PTC were multifocality, tumor size, and the number of central LNM. The prediction model can better predict the presence of lateral LNM.

Canadian Consensus for Biomarker Testing and Treatment of TRK Fusion Cancer in Pediatric Patients. Curr Oncol 2021; 28:346-366. [PMID: 33435412 PMCID: PMC7903261 DOI: 10.3390/curroncol28010038] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 01/03/2021] [Accepted: 01/05/2021] [Indexed: 12/11/2022] Open
Abstract
Neurotrophic tyrosine receptor kinase gene fusions (NTRK) are oncogenic drivers present at a low frequency in most tumour types (<5%), and at a higher frequency (>80%) in a small number of rare tumours (e.g., infantile fibrosarcoma [IFS]) and considered mutually exclusive with other common oncogenic drivers. Health Canada recently approved two tyrosine receptor kinase (TRK) inhibitors, larotrectinib (for adults and children) and entrectinib (for adults), for the treatment of solid tumours harbouring NTRK gene fusions. In Phase I/II trials, these TRK inhibitors have demonstrated promising overall response rates and tolerability in patients with TRK fusion cancer who have exhausted other treatment options. In these studies, children appear to have similar responses and tolerability to adults. In this report, we provide a Canadian consensus on when and how to test for NTRK gene fusions and when to consider treatment with a TRK inhibitor for pediatric patients with solid tumours. We focus on three pediatric tumour types: non-rhabdomyosarcoma soft tissue sarcoma/unspecified spindle cell tumours including IFS, differentiated thyroid carcinoma, and glioma. We also propose a tumour-agnostic consensus based on the probability of the tumour harbouring an NTRK gene fusion. For children with locally advanced or metastatic TRK fusion cancer who have either failed upfront therapy or lack satisfactory treatment options, TRK inhibitor therapy should be considered.

Abstract
Thyroid nodules are less common in children than in adults. However, pediatric thyroid nodules have a higher rate of malignancy compared to those in adults, and increased risk of metastasis and recurrence. In the present study, we analyzed the clinical features as well as laboratory and thyroid ultrasound (US) findings of children and adolescents with thyroid nodules to identify predictive factors of thyroid cancer. We retrospectively analyzed 275 patients with thyroid nodules under 18 years of age who visited Severance Children's Hospital between January 2005 and May 2017. Among them, 141 patients who underwent ultrasonography-guided fine needle aspiration biopsy (FNAB), and four patients without FNAB who underwent surgical resection, were included in this study. The remaining 125 patients without FNAB and five patients with follow-up loss after FNAB were excluded. Clinical, laboratory, and US data were evaluated in 145 patients to establish the potential predictive factors of thyroid cancer. Thyroid malignancies were observed in 101 patients. Grade 2 goiters were seen more often in benign nodule group. Hypoechoic nodules, nodules with microcalcifications, abnormal lymph nodes, and irregular margins were findings significantly associated with thyroid cancer. The findings of hypoechoic nodule, nodule with microcalcifications, and abnormal lymph nodes showed statistical significance in predicting thyroid cancer.Conclusion: Hypoechoic nodules, nodules with microcalcifications, and abnormal lymph nodes are predictive factors for thyroid cancer in children. Therefore, further diagnostic evaluations, including FNAB, should be considered in patients with such findings.What is Known:• Thyroid nodules are less common in children than in adults, but pediatric thyroid nodules have a higher rate of malignancy, and also have increased risk of metastasis and recurrence.• Research on ways to predict thyroid cancer have mostly been accomplished in adult patients, and the application of risk stratification system has not been fully satisfactory in children, which requires further studies in pediatric thyroid nodules.What is New:• Hypoechoic nodules, nodules with microcalcifications, and abnormal lymph nodes are predictive factors for thyroid cancer in Korean children.

Abstract
BACKGROUND The risk factors for rapid growth and early metastasis of papillary thyroid carcinoma (PTC) and the role of coexisting Graves' disease in the clinical course of PTC remain uncertain in children. CASE DESCRIPTION We report on a Japanese girl, whose PTC rapidly grew and metastasized within 4 years. Graves' disease was diagnosed by the presence of serum TSH receptor antibodies at 8 years of age when thyroid ultrasonography detected no nodules. After 4 years of effective treatment with thiamazole, multifocal nodules - up to 47 mm in diameter - were detected on thyroid ultrasonography. Chest CT scan revealed multiple metastatic lesions in the lung. After total thyroidectomy, PTC was pathologically diagnosed. The patient underwent two courses of radioactive iodine (RAI) treatment, but the pulmonary metastatic lesions did not take up the RAI. Molecular analyses of the PTC tissue identified a TFG/NTRK1 chimeric gene and disclosed the preserved expression of TSHR and the reduced expression of SLC5A5 compared with non-tumor thyroid tissue. CONCLUSIONS Rapid growth and early metastasis of PTC with coexisting Graves' disease in this patient can be related to a combination of multiple factors including preserved TSHR expression, reduced SLC5A5 expression, and TFG/NTRK1 rearrangement.

Abstract
INTRODUCTION Thyroid cancer in children is a hot topic because of the large clinical heterogeneity and the risk of severe complications. We aimed to study 1. The frequency, 2. Etiology, and 3. Risk factors of post-surgery complications of thyroid cancer. MATERIAL AND METHODS A retrospective analysis including risk factors for post-surgery complications of patients treated for thyroid malignancies in years 2006-2018 was performed. RESULTS Over a period of 12 years 22 patients with thyroid malignancy (68% female; 12.6 ± 4.0 years of age, median follow-up 6 years) were identified. Histologically, 12 (55%) patients had papillary carcinoma. Six patients (27.3%) had multiple endocrine neoplasia type 2 (MEN2) syndrome, 3 (13.7%) patients had medullary carcinoma and 1 patient had follicular carcinoma. Neck lymph node metastases were diagnosed in 8 (36.4%), distant metastases in 6 (27.3%), and both locations were involved in 4 (18.2%) patients. Six (27.3%) children had surgical complications: 1 child had unilateral vocal cord paralysis and transient hypoparathyroidism and 5 had transient hypoparathyroidism. The higher risk of surgery complications in forward stepwise logistic regression was associated in with distant metastases (R2 = 0.584, OR 52.63, p = 0.010). CONCLUSIONS Postoperative complications were significantly associated with presence of distant metastases. Favorable results were observed in with children with MEN2 syndrome.

Abstract
Background Thyroid cancer is the most common endocrine malignant disease in children and adolescents. There is a trend of more conservative strategies including lobectomy and less radioactive iodine therapy (RAI) in multifocal papillary thyroid cancer (PTC) for its good survival outcome. The aim of our study was to define long-time outcome of a large cohort of multifocal PTC patients less than 20 years old treated at our institution. Methods Data were collected from 276 cases who were initially diagnosis of PTC under the age of 20 from January 2006 to December 2015 at Fudan University Shanghai Cancer Center. All patients received total/near total thyroidectomy or lobectomy. Therapeutic central-compartment (level VI) and lateral neck lymph node dissection performed for patients with clinically involved neck nodes. RAI therapy used in selected patients. No patients received chemotherapy or kinase inhibitor therapy. Thyroid-stimulating hormone (TSH) suppression therapy was performed in all patients for at least 5 years. Results Ninety among 276 were multifocal PTC patients and included in this study. The median follow-up time was 54.28 months, ranging from 6.10 to 141.27 months. Fifteen patients had tumor recurrence during the follow-up. On Kaplan-Meier survival curves, lymphovascular invasion and extrathyroidal extension was associated with a decline in recurrence-free survival. However, there was no difference in recurrence-free survival curves in patients no matter which treatment they had received, either lobectomy or total thyroidectomy, RAI or not. Conclusions More conservative strategies including lobectomy and less RAI in multifocal PTC among children and adolescents are safe and effective.

Abstract
Differentiated thyroid cancer (DTC) is the most common cancer in adolescents and young adults. In 2015, the American Thyroid Association published guidelines for management of pediatric DTC. We report our institutional experience and highlight changing practices and new opportunities. A retrospective analysis of all patients diagnosed with DTC from 2001 to 2016 was performed. Among 59 eligible patients, 31 (53%), 15 (25%), and 13 (22%) had low-risk, intermediate-risk, and high-risk disease, respectively. Half (15/31) of low-risk and all intermediate-risk/high-risk patients received radioactive iodine (I-131) ablation. For low-risk patients, average I-131 dose decreased from 80 to 42.05 mCi, and the percentage of patients who received I-131 decreased over time. Eleven of 16 patients with tumor genomic data were found to have somatic targetable (n=6) or germline (n=5) mutations. Persistent/recurrent disease was only present in high-risk (n=8) and intermediate-risk (n=1) patients. Two patients with iodine-refractory disease received trametinib to enhance radioiodine uptake. All patients were alive at follow-up (median, 5 y; range, 1 to 15 y). Coincident with the recent American Thyroid Association guidelines, the use of I-131 in low-risk patients has decreased over time in our practice. Tumor sequencing and cancer genetic evaluation may help redefine opportunities for treatment of high-risk patients and family counseling.

Abstract
BACKGROUND Thyroid cancer constitutes a major and increasing proportion of head and neck cancers in children and adolescents. The purpose of this study was to determine the incidence and survival of thyroid cancer in Danish patients aged 0-24 years from 1980 to 2014. METHODS Patients aged 0-24 years registered with primary thyroid cancer in the Danish Cancer Registry or the Danish Pathology Data Bank during 1980-2014 were included. Crude incidence rates and age-adjusted incidence rates (AAIR) per 100,000, average annual percent change (AAPC), and overall survival (OS) were evaluated in relation to sex, histopathological tumor type, age at diagnosis, and year of diagnosis. RESULTS A total of 297 thyroid cancer patients (72% female, 72% papillary carcinoma) were identified. The AAIR per 100,000 increased significantly from 0.36 in 1980 to 0.97 in 2014, with an AAPC of 2.9%. There was no significant increase in incidence among children and adolescents (0-17 years). However, among young adults (18-24 years), a significant increase in incidence was observed (AAPC 3.7%). The incidence of thyroid cancer increased with age from 0.05 among infants aged 0 years to 1.73 among young adults aged 24 years. Female patients and papillary carcinoma showed significant increase in incidence (AAPC 3.3% and 3.2%), whereas male patients and other histopathological tumor types showed no change. The 15-year OS was 99%. The lowest 15-year OS was observed among patients with medullary carcinomas at 96%. There was no significant difference in OS between groups based on histopathological tumor type, and there was no significant change in OS over time. CONCLUSION In this nationwide study, no change in OS was observed, but a significant increase was seen in the incidence of thyroid cancer among young adults (aged 18-24 years), mainly attributed to an increase among females and patients with papillary carcinoma. No increase in incidence was seen among children and adolescents. These findings demonstrate the excellent prognosis for children and adolescents diagnosed with thyroid cancer.

Abstract
In adolescents and young adults, thyroid cancer accounts for 13% of all invasive neoplasms, being three times more frequent in females, but overdiagnosis and overtreatment are common. There are two therapeutic approaches, one radical and no longer preferred in all instances, and the other conservative. Permanent complications of surgery and metabolic irradiation can affect quality of life and carry an economic burden. The overall survival rate approaches 100% for patients with differentiated thyroid cancer regardless of the extent of treatment. Medullary thyroid carcinoma is a very different entity, occurring most frequently in the context of hereditary tumor susceptibility syndromes.

Abstract
Acute suppurative thyroiditis is a rare, potentially life-threatening condition. We report the case of a 17-year-old male who initially presented with a thyroid abscess. Due to persistent symptoms and lack of evidence for underlying predisposing factors, he was followed closely and subsequently diagnosed with papillary thyroid cancer. He was successfully managed with surgery. His clinical course, radiological evaluation, and pathology reports are presented here along with a review of the literature. This case of papillary thyroid cancer highlights the need for close follow-up of patients presenting with a thyroid abscess, when other predisposing risk factors are not evident.

Abstract
Thyroid nodules are detected in up to 50 to 60% of healthy subjects. Most nodules do not cause clinically significant symptoms, and as a result, the main challenge in their management is to rule out malignancy, with ultrasonography (US) and fine-needle aspiration (FNA) biopsy serving as diagnostic cornerstones. The key issues discussed in these guidelines are as follows: (1) US-based categorization of the malignancy risk and indications for US-guided FNA (henceforth, FNA), (2) cytologic classification of FNA samples, (3) the roles of immunocytochemistry and molecular testing applied to thyroid FNA, (4) therapeutic options, and (5) follow-up strategy. Thyroid nodule management during pregnancy and in children are also addressed. On the basis of US features, thyroid nodules may be categorized into 3 groups: low-, intermediate-and high-malignancy risk. FNA should be considered for nodules ≤10 mm diameter only when suspicious US signs are present, while nodules ≤5 mm should be monitored rather than biopsied. A classification scheme of 5 categories (nondiagnostic, benign, indeterminate, suspicious for malignancy, or malignant) is recommended for the cytologic report. Indeterminate lesions are further subdivided into 2 subclasses to more accurately stratify the risk of malignancy. At present, no single cytochemical or genetic marker can definitely rule out malignancy in indeterminate nodules. Nevertheless, these tools should be considered together with clinical data, US signs, elastographic pattern, or results of other imaging techniques to improve the management of these lesions. Most thyroid nodules do not require any treatment, and levothyroxine (LT4) suppressive therapy is not recommended. Percutaneous ethanol injection (PEI) should be the first-line treatment option for relapsing, benign cystic lesions, while US-guided thermal ablation treatments may be considered for solid or mixed symptomatic benign thyroid nodules. Surgery remains the treatment of choice for malignant or suspicious nodules. The present document updates previous guidelines released in 2006 and 2010 by the American Association of Clinical Endocrinologists (AACE), American College of Endocrinology (ACE) and Associazione Medici Endocrinologi (AME).

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
OBJECTIVE To increase awareness of the important differential diagnosis between thyroid cancer and intrathyroidal ectopic thymic tissue when performing neck ultrasound (US) in pediatric patients. METHODS We report 2 cases of intrathyrodal thymic tissue that were initially referred as possible papillary thyroid cancer (PTC). US and cytologic features of these lesions are described, and the distinguishing US characteristics of intrathyroidal thymic tissue versus PTC are discussed. RESULTS Two pediatric patients who underwent thyroid US were diagnosed with thyroid nodules suggestive of PTC. The suspected lesions in both patients exhibited an echo texture identical to the normal thymus gland. Fine-needle aspirate (FNA) biopsy of the nodule in the first case revealed numerous lymphocytes with positive immunocytochemical staining for CD3, confirming a T cell phenotype. The second patient underwent follow-up US imaging 8 months later that showed stability of the intrathyroidal nodule. CONCLUSION Intrathyroidal ectopic thymic tissue can be mistaken for PTC as both conditions have similar US features. Increased awareness of this unique mimicry may help to avoid unnecessary invasive investigations and surgery in these young patients.

Abstract
Although surgical conditions of the thyroid gland are uncommon in children, the increased incidence of thyroid cancer, combined with the fact that children's hospitals are increasingly treating older adolescents, means that it is important that all pediatric surgeons have a knowledge of these conditions. Abnormalities of the thyroid can be associated with abnormalities of thyroid function (hyperthyroidism or hypothyroidism) and/or can be associated with symmetrical or asymmetrical enlargement of the gland.

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
BACKGROUND As in adults, thyroidectomy in pediatric patients with differentiated thyroid cancer is often followed by (131)I remnant ablation. A standard protocol is to give normalizing oral thyroxine (T(4)) or triiodothyronine (T(3)) after surgery and then withdraw it for 2 to 6 weeks. Thyroid remnants or metastases are treated most effectively when serum thyrotropin (TSH) is high, but prolonged withdrawals should be avoided to minimize hypothyroid morbidity. METHODS A published feedback control system model of adult human thyroid hormone regulation was modified for children using pediatric T(4) kinetic data. The child model was developed from data for patients ranging from 3 to 9 years old. We simulated a range of T(4) and T(3) replacement protocols for children, exploring alternative regimens for minimizing the withdrawal period, while maintaining normal or suppressed TSH during replacement. The results are presented with the intent of providing a quantitative basis to guide further studies of pediatric treatment options. Replacement was simulated for up to 3 weeks post-thyroidectomy, followed by various withdrawal periods. T(4) vs. T(3) replacement, remnant size, dose size, and dose frequency were tested for effects on the time for TSH to reach 25 mU/L (withdrawal period). RESULTS For both T(3) and T(4) replacement, higher doses were associated with longer withdrawal periods. T(3) replacement yielded shorter withdrawal periods than T(4) replacement (up to 3.5 days versus 7-10 days). Higher than normal serum T(3) concentrations were required to normalize or suppress TSH during T(3) monotherapy, but not T(4) monotherapy. Larger remnant sizes resulted in longer withdrawal periods if T(4) replacement was used, but had little effect for T(3) replacement. CONCLUSIONS T(3) replacement yielded withdrawal periods about half those for T(4) replacement. Higher than normal hormone levels under T(3) monotherapy can be partially alleviated by more frequent, smaller doses (e.g., twice a day). LT(4) may be the preferred option for most children, given the convenience of single daily dosing and familiarity of pediatric endocrinologists with its administration. Remnant effects on withdrawal period highlight the importance of minimizing remnant size.

Abstract
Thyroid cancers represent the largest group of pediatric carcinomas. Unlike other cancers of childhood, they have not been prospectively studied; instead adult data has been extrapolated to childhood and adolescent treatment. In this article we review the treatment of both well differentiated thyroid cancer (WDTC), as well as medullary thyroid cancer (MTC). The approach to both cancers relies on a low threshold of suspicion, and a willingness to biopsy suspicious lesions. Surgery remains the primary method of curing these patients, although radioactive iodine (RAI) may offer some benefit in WDTC for selected patients. For patients with MTC new medications, such as Vandetanib, may offer some adjuvant benefit following surgery. Lastly, suppression of thyroid stimulating hormone (TSH) may be one of the most beneficial treatments for WDTC.

Abstract
BACKGROUND Pediatric patients present with thyroid nodules less often than adults, but the rate of malignancy is much higher. This study was designed to determine the ability of fine-needle aspiration cytology (FNA) to diagnose accurately and facilitate management of thyroid neoplasms in pediatric patients. METHODS A retrospective study revealed 110 patients <19 years old who had undergone thyroid surgery and FNA biopsy at two academic institutions over the last 28 years. FNA sensitivity for diagnosing papillary thyroid cancer (PC) and follicular neoplasm (FN) was investigated. RESULTS Of 110 patients who presented for surgery, 27 had PC and 33 had a FN: 4 follicular carcinomas (FCs) and 29 follicular adenomas (FAs). Among the PCs patients, the FNA results were as follows: 1 (4%) nondiagnostic, 6 (22%) atypical, 2 (7%) benign, and 18 (67%) malignant lesions. The sensitivity of a malignant FNA was 90% for diagnosing a PC. Sensitivity of an atypical FNA was 75% for FCs and 69% for FAs, giving an overall FN sensitivity of 70%. Of the atypical FNA readings, 60% had confirmed histological atypical features, and 19% were malignant. In 95% of the malignant FNA reports, final histology confirmed PC, resulting in a positive predictive value of 95%. CONCLUSIONS FNA biopsy can reliably diagnose malignancy in pediatric thyroid patients and should be used as a standard technique to indicate surgical treatment. Atypical or suspicious FNA results do not predict cancer effectively, confirming the current accepted practice for adults that diagnostic excision is required to exclude malignancy in pediatric patients.

Abstract
OBJECTIVE To evaluate the clinical outcome in childhood patients receiving postoperative high-dose radioiodine therapy for advanced differentiated thyroid carcinoma. METHOD Patients under 18 years old with neck diseases (n = 4) or distant metastases (n = 10) received postoperative radioiodine ablation and repeated treatments for a median of 2 (0.8 10) years with an averaged activity of 25.0 (7.0 72.2) GBq. RESULTS Partial remission was achieved in 6, stable disease in 6 and progressive disease in 2 patients, without severe side effects except for two Grade 1 and one Grade 2 WHO haematological toxicity. The median survival time from diagnosis to the last treatment sessions was 5.3 (range, 0.7 14.5) years. CONCLUSION High-dose radioiodine treatment was well tolerated with satisfactory outcome in childhood patients with advanced differentiated thyroid carcinoma.

Abstract
Ectopic intrathyroidal thymic tissue is a rare occurrence; parathyroid glands sometimes occur in an intrathyroidal location, but this is uncommon. We report a 6-year-old boy who was noted to have a solitary thyroid nodule on ultrasound. A hemithyroidectomy was performed, and histological investigation revealed that the nodule consisted of ectopic intrathyroidal thymus tissue surrounding a well-defined parathyroidal gland. This condition is an exceedingly rare cause of a thyroid nodule, but intrathyroidal thymic tissue should probably be included in the differential diagnosis of solitary thyroid nodules.

Abstract
The territory of the Czech Republic was contaminated as a result of the breakdown in the Chernobyl nuclear power plant in 1986. The Czech population received low doses of ionising radiation which, though it could not cause a deterministic impact, could have had stochastic effects expressed in the years following the accident. Twenty years after the accident is a long enough time to assess its stochastic effects, primarily tumours and genetic impairment. The moderate amount of radioactive fallout received by the Czech population in 1986 increased thyroid cancer in the following years; on the other hand, no obvious genetic impact was found.

Abstract
We investigated selected gene targets to differentiate radiation-induced papillary thyroid cancers (PTCs) from other etiologies. Total RNA was isolated from 11 post-Chernobyl PTCs and 41 sporadic PTCs characterized by a more aggressive tumor type and lacking a radiation exposure history. RNA from 10 tumor samples from both groups was pooled and hybridized separately on a whole genome microarray for screening. Then 92 selected gene targets were examined quantitatively on each tumor sample using an RTQ-PCR-based low-density array (LDA). Screening for more than fivefold differences in gene expression between the groups by microarray detected 646 up-regulated and 677 down-regulated genes. Categorization of these genes revealed a significant (P < 0.0006) over-representation of the number of up-regulated genes coding for oxidoreductases, G-proteins and growth factors, while the number of genes coding for immunoglobulin appeared to be significantly down-regulated. With the LDA, seven genes (SFRP1, MMP1, ESM1, KRTAP2-1, COL13A1, BAALC and PAGE1) made a complete differentiation between the groups possible. Gene expression patterns known to be associated with a more aggressive tumor type in older patients appeared to be more pronounced in post-Chernobyl PTC, thus underlining the known aggressiveness of radiation-induced PTC. Seven genes were found that completely distinguished post-Chernobyl (PTC) from sporadic PTC.

Abstract
In 1996, the authors were asked to review the subject of thyroid cancer in children. Over the subsequent decade, much has been learned about the treatment and outcome of these uncommon tumors. We now recognize quantitative and perhaps qualitative differences in genetic mutations and growth factor expression patterns in childhood thyroid cancers compared with those of adults. We also know that thyroid cancers induce a robust immune response in children that might contribute to their longevity. Patients under 10 years of age probably represent a unique subset of children at particularly high risk for persistent or recurrent disease; the management of these patients is under evaluation. We remain limited in our knowledge of how to stratify children into low- and high-risk categories for appropriate long-term follow-up and in our knowledge of how to treat children who have detectable serum thyroglobulin but negative imaging studies. In this article, the authors update our understanding of thyroid cancers in children with special emphasis on how these data relate to the current guidelines for management of thyroid cancer developed by the American Thyroid Association Taskforce. The limited data regarding management of children who have detectable serum thyroglobulin but negative whole-body scans are also reviewed.

Abstract
Aproximadamente 10% das neoplasias de tireóide aparecem abaixo dos 21 anos e representam 3% das neoplasias da infância, com predomínio em meninas (2F:1M). São papilíferos em 90% casos e mais freqüentemente bilaterais, multifocais e de maior dimensão. Invasão de cápsula e metástases ganglionar ou pulmonar são mais freqüentes que no adulto. O efeito carcinogênico da radiação é especialmente importante na criança pré-púbere. Em 5% dos casos de PTC existe história familial. Genes como o RET/PTC, RAS e BRAF estão habitualmente envolvidos na gênese do processo. A apresentação clínica pode ser nódulo cervical (90% casos) sem que represente um fator de pior prognóstico. O US e a PAAF são procedimentos diagnósticos valiosos. O tratamento deve ser cirúrgico (tireoidectomia total com esvaziamento ganglionar) seguido de PCI e radioterapia ablativa. A substituição com L-tiroxina deve objetivar a supressão crônica do TSH. O prognóstico ao longo prazo é melhor que no adulto. A quantificação da Tg plasmática também é útil na detecção da doença residual.

Abstract
Insular-type carcinoma of the thyroid is a rare form of undifferentiated thyroid cancer. The manifestation of disease occurs mainly in adults and is extremely rare in children. Prognosis of this type of thyroid carcinoma is unfavorable in childhood. Because of its rarity, it is not yet clear whether these tumors carry the same risk of progression. Therapy of choice is total thyroidectomy combined with a cervical lymph node dissection. In children, surgery is associated with a higher risk of recurrent nerve palsy and loss of parathyroid glands than in adults. Therefore, identification and protection of the recurrent laryngeal nerve using electrical neuromonitoring as well as exact preparation of parathyroid glands may reduce these risks. The history of a 10-year-old girl with insular-type thyroid carcinoma is presented. Surgical considerations such as total thyroidectomy vs less-than-total thyroidectomy with unilateral or bilateral cervical lymph node dissection are presented. Prognosis concerning morbidity, pointing out the aspect of electrical neuromonitoring and precaution of parathyroid glands, and survival rate of this extremely rare entity are discussed.

Abstract
Fine-needle aspiration (FNA) of the thyroid is seldom performed in the pediatric population. Therefore, the clinical utility of thyroid FNA in this patient group has not been adequately addressed. A 15 yr retrospective review of the cytopathology archives at the participating institutions was performed to identify cases of thyroid FNA performed in pediatric patients. The medical records of these cases were reviewed, including the surgical pathology reports of those patients who had subsequently undergone surgical resection. One hundred one specimens from 82 patients were identified. Of these, 40 had a cytopathologic diagnosis of carcinoma, "suspicious" for carcinoma, neoplasm, or atypia, 48 were benign, and 13 were unsatisfactory. Of the 82 patients, 45 underwent partial or total thyroidectomy. Twenty-two (49%) of these were found to harbor a malignant neoplasm (18 papillary carcinomas). The diagnostic sensitivity for identifying a lesion was 87% (26/30) and the diagnostic specificity was 92% (47/51). There were four false-positives and four false-negatives in the review, yielding a positive predictive value of 87% and a negative predictive value of 92%. We conclude that FNA is a useful adjunct to the management of thyroid lesions in the pediatric population, with good diagnostic accuracy. Although thyroid neoplasms are relatively rare in children, our experience demonstrated that 40% of thyroid masses referred for FNA had an interpretation that caused concern, ranging from "atypical" to carcinoma. Additionally, a benign diagnosis by FNA may avoid unnecessary surgery with its potential complications, a significant consideration for this age group.

Abstract
We studied 20 patients with differentiated thyroid carcinoma undergoing radioiodine therapy (> or = 100 mCi dose) before the age of 21: 10 patients without distant metastases received a mean dose of 145 mCi and 10 with lung involvement received 270 mCi. One or more years after ablative therapy, xerostomia was present in two patients but was not accompanied by more severe complications such as oral ulcers or fissures, and 99mTcO4- scintigraphy confirmed salivary dysfunction. One patient showed keratoconjunctivitis sicca. Blood counts did not reveal abnormalities caused by radioiodine therapy. FSH was normal in 18 patients. Patients with elevated levels had received radioiodine just over a year ago and repetition of the exam after 6 months showed that FSH had returned to normal. The 6 male patients had normal LH and testosterone levels. Analysis did not reveal signs of pulmonary fibrosis secondary to treatment in the 10 cases with iodine-accumulating metastases in this organ. Our data suggest that ablative therapy employing a dose of 100 to 300 mCi is safe in young individuals, but persistent complications such as salivary dysfunction and conjunctivitis may occur.

Abstract
INTRODUCTION Optimal treatment of recurrent papillary thyroid carcinoma (PTC) in children remains controversial. We reviewed our experience with recurrent PTC to better identify children diagnosed with it. AIMS The objective of this study was to determine the risk factors, optimal treatment, complications, and prognosis of recurrent PTC in children. METHODS This is a retrospective review of all thyroid resections for children aged 18 years or younger who have PTC at a single institution from 1987 to 1999. RESULTS Thirty-six children, 7 boys (19%) and 29 girls (81%), underwent initial cervical exploration for PTC. Lymph node involvement was noted in 25 patients (69%); however, there was no distal disease. An equal number of children underwent subtotal thyroidectomy (n = 18) and total (n = 18) thyroidectomy as their initial operation. Papillary thyroid carcinoma recurrences developed in 17 patients (47%) a median of 7 months (range, 1-43 months) after their initial operation. Recurrence was more common for patients with lymph node involvement (P < .01) and multiple nodules (P < .05) at presentation. Recurrence developed in 5 patients after subtotal thyroidectomy and in 12 patients after total thyroidectomy. Sixteen children with recurrent PTC had a second operation and 6 required a third operation. Total operative complications included 2 patients with permanent hypocalcemia and 1 patient with permanent recurrent laryngeal nerve injury, all of whom had a total thyroidectomy. No patient died; however, 3 continue to harbor disease. Mean follow-up for patients with PTC was 65 months (range, 15 to 144 months). CONCLUSIONS Thyroid resection combined with selective use of radioactive iodine ablation is a safe and effective treatment for recurrent PTC in children. The best predictors of this recurrent disease are lymph node involvement and multiple thyroid nodules at presentation.

Abstract
OBJECTIVES/HYPOTHESIS The objective was to determine clinical features and clinical outcomes for pediatric thyroid carcinoma. STUDY DESIGN Cross-sectional analysis of national cancer database. METHODS The Surveillance, Epidemiology, and End Results database (1988-2000) was surveyed, extracting all cases of pediatric thyroid carcinoma. Clinical features including age, gender, tumor type, tumor size, nodal disease, treatment modality, and survival variables were retrieved. Kaplan-Meier survival analysis was conducted to determine actuarial survival according to histological type. Cox regression analysis was conducted to determine prognostic factors affecting survival in pediatric carcinoma. RESULTS In all, 566 cases of thyroid carcinoma were extracted for the time period. Mean patient age at presentation was 16.0 years, with a female predominance (84.8%). There were 378 cases of papillary carcinoma, 137 cases of follicular variant of papillary carcinoma, and 51 cases of follicular carcinoma. The average tumor size was 2.6 cm, and 37.1% of patients presented with positive nodal disease. Overall survival was excellent with mean survivals greater than 145 months for each histological type. Follicular carcinoma exhibited a slightly poorer survival that was statistically significant (P = .017) CONCLUSION Pediatric thyroid carcinoma primarily affects girls. Clinical features of tumor presentation are similar to those of adults with thyroid carcinoma. However, overall survival for pediatric thyroid carcinoma is excellent, with few patients dying of disease.

Abstract
BACKGROUND The Chernobyl nuclear accident of 1986 caused a dramatic increase in the incidence of thyroid cancers in exposed children in Belarus. Airborne radioactivity from the reactor spread over northern Italy, where rainout gave rise to low levels of radioactivity at ground level. PATIENTS AND METHODS As the latency between exposure to ionising radiation and development of thyroid cancer is thought to be about 10 years, in 1996/1997 all children born in 1985 and 1986 and attending school in an area of Milan, Italy were examined for thyroid nodules. A total of 3949 children were examined by two physicians blinded to the examination and diagnosis of the other. The children were to be reassessed in 2001/2002. RESULTS In total, 1% had palpable nodules. The nodule diagnoses were: Hurtle cell adenoma (one), thyroglossal duct cyst (one), thyroid cyst (four) and thyroiditis (four). The prevalence of thyroid disease in the cohort was indistinguishable from that of populations not exposed to radioactive pollution. Only 10 children re-presented for examination 5 years later; all were negative. The direct costs of the study were estimated at 21,200 Euros. CONCLUSION The high cost of the study in relation to reassuring lack of increase in thyroid nodule prevalence suggests that further studies are not justified.

Abstract
Tumores tireoideanos são raros na infância e adolescência. Foram revisados os prontuários de quinze pacientes (8 do sexo feminino) com idades entre 5,8 e 15,2 anos, atendidos na Unidade de Endocrinologia Pediátrica (UEP) do HC-UFPR entre fevereiro de 1988 e março de 2003. Nódulo cervical anterior foi a queixa inicial mais freqüente. Dez pacientes eram portadores de carcinoma papilífero (CP), quatro apresentavam carcinoma medular (CMT; dos quais, três com NEM-2B) e um, carcinoma folicular. Dois pacientes com NEM-2B apresentam mutação de novo (Met918Thr) do proto-oncogene RET. PAAF, efetuada em dez pacientes, foi positiva para neoplasia em cinco deles. Todos os pacientes foram submetidos a tireoidectomia total. Terapia adjuvante com 131I foi realizada em dez pacientes. Dois pacientes faleceram por doença não relacionada ao tumor. Nove pacientes não apresentam evidência clínica ou laboratorial do tumor; um (CP) apresentou recidiva 5 anos após o tratamento inicial e três (1 CP, 2 CMT) ainda têm evidência da doença. Nossos dados estão de acordo com a literatura em relação ao prognóstico e manifestações clínicas. Entretanto, a prevalência de CMT (27%), a distribuição por sexo e os resultados da PAAF diferem da maioria das casuísticas publicadas, o que pode ser atribuído ao número de casos aqui relatado.

Abstract
The influence of clinical and treatment factors on the risk of recurrence was analyzed from a retrospective series of 74 children and adolescents with thyroid cancer (55 girls, 19 boys; age 2-20 years). Two groups, comparable in terms of age, sex, and previous radiotherapy, were compared according to the presence (group 1) or absence (group 2) of cervical lymph nodes identified by palpation or ultrasonography. Total thyroidectomy (TT) with lymph node dissection (LND) was performed in the 19 group 1 patients, whereas in group 2 patients (n = 55) lobectomy was performed in 29, TT in 26, and LND in 7. Pathology studies showed papillary thyroid carcinoma in 95% of cases. In group 1, tumors were more frequently multifocal (89% vs. 16% in group 2), invasive with extension beyond the thyroid capsule (68% vs. 5% in group 2), and of the diffuse sclerosing variety (63% vs. 4% in group 2) (p < 0.001). With a median follow-up of 61 months, lymph node recurrence was seen in 53% of group 1 patients and in no patients in group 2. Three group 2 patients (10%) were reoperated for a local recurrence after lobectomy. Risk factors for reintervention were young age (< 15 years) (p < 0.01) and cervical lymph nodes (p < 0.001). Survivals without reintervention at 5 and 10 years were, respectively, 58% and 38% for group 1 and 94% and 90% for group 2 (p < 0.001). At the time of analysis, 68% of group 1 patients and 98% of group 2 patients were in remission. In conclusion, the presence of palpable cervical lymph nodes at diagnosis is associated with more invasive forms of malignancy and is a predictive factor of recurrence regardless of the extent of the initial surgery.

Abstract
Since the mortality rate for childhood differentiated thyroid carcinoma is nearly zero, the focus must be to minimise morbidity following treatment. Our aim was to analyse early and late adverse events. Twenty-five of 26 children treated between 1962 and 2002 were evaluated. Median follow-up was 14.2 years (range 0.9-39.4 years). All underwent total thyroidectomy, 15 (60%) with lymph node dissection and 15 (60%) with adjuvant radio-iodide therapy. Mortality was zero. Seven developed recurrent disease, two developed a third recurrence. Twenty-one (84%) had > or =1 adverse event. Eight had permanent hypoparathyroidism (PH), six permanent recurrent nerve paralysis (PRNP) and two Horner's syndrome. Risk factors for PH and PRNP were total thyroidectomy with lymph node dissection (RR: 6.45, P = 0.015) and recurrent nerve tumour encasement (RR: 8.00, P = 0.001), respectively. Other adverse events were fatigue (n = 5), scar problems (n = 4) and chronic myeloid leukaemia (n = 1). These results emphasise the need to improve treatment strategies.

Abstract
AIM OF THE STUDY The aim of this retrospective study was to propose a therapeutic strategy according to clinic and pathologic presentations, in differentiated thyroid carcinoma in patients less than 20 years of age. PATIENTS AND METHODS From 1995 to 2002, 74 patients less than 20 years of age were operated on for a differentiated thyroid carcinoma. Patients were divided in two groups according to the presence of lymph node (LN) detected before operation (19 "with LN" and 55 "without LN"). RESULTS Surgery consisted of total thyroidectomy and lymph node dissection in the group "with LN". In the second group "without LN", total thyroidectomy was performed in 19 patients (associated with lymph node dissection in seven) and loboisthmectomy in 29 patients. Post operative radio iodine ablation was performed in 25 patients (16 "with LN" and nine "without LN"). During the follow up (median 71 months), 9/19 patients "with LN" underwent surgery for lymph node recurrence. Four patients of the "without LN" group were reoperated for recurrence in the controlateral thyroid lobe after initial loboisthmectomy. Initial presence of lymph nodes was a risk factor for reoperation. Survival without reoperation at 5 and 10 years was 58% and 38% for the "with LN" group and 96% and 91% for the "without LN" group respectively (P < 0.001). At the time of analysis, all patients were alive. Ninety percent of patients were in remission (68% of "with LN" and 98% of "without LN" patients). CONCLUSION The risk of reoperation for lymph node recurrence during first post operative year is important in the "with LN" group. Therapeutic strategy consists of total thyroidectomy, complete lymph node dissection, radio iodine administration and l-thyroxine treatment. In "without LN" patients risk of lymph node recurrence is low. Treatment consist of total thyroidectomy, lymph node dissection and radio iodine administration are not systematic.

Abstract
The sodium-iodide symporter (NIS) is expressed by papillary (PTC) and follicular (FTC) thyroid carcinoma, and is essential for iodine uptake. We hypothesized that PTC and FTC with detectable NIS immunostaining would be more amenable to radioactive iodine ((131)I) treatment and follow a more benevolent course. To test this, we determined NIS expression by immunohistochemistry in 23 PTC, 9 FTC, and 12 benign thyroid lesions from children and adolescents. NIS expression was determined by two blinded examiners and graded as absent = 0, minimal = 1, moderate = 2, intense = 3, and very intense = 4. NIS was detected in 35% (eight of 23) of PTC, 44% (four of 9) of FTC, 25% (two of eight) of benign tumors, and 100% (four of four) of autoimmune lesions. The intensity of NIS expression was similar in PTC (0.61 +/- 0.24), FTC (0.56 +/- 0.24), and benign tumors (0.50 +/- 0.33) but was more intense in autoimmune lesions (3.0 +/- 0.7, p < 0.005). Distant metastases were found only among PTC with undetectable NIS (two of 15, 13%), and recurrence developed exclusively from PTC and FTC with undetectable NIS (four of 20, 20% versus zero of 12, p = 0.043). The dose of iodine 131 required to achieve remission in the five patients with PTC who had undetectable NIS (213.3 +/- 53 mCi) was greater than that required by patients with similar age and extent of disease for whom NIS expression is unknown (109 +/- 22 mCi, p = 0.06). We conclude that NIS expression is associated with a lower risk of recurrence for PTC and FTC of children and adolescents.

Abstract
The factor(s) that control metastasis of thyroid carcinoma are unknown, but the matrix metalloproteinases (MMPs) are excellent candidates. MMP-1, membrane-type-1 MMP (MT1-MMP), and tissue inhibitor of MMP-1 (TIMP-1) have all been implicated, but the site of production and importance are disputed. In vitro, normal thyroid cells secrete TIMP-1, while thyroid cancer cells secrete TIMP-1 and MMP-1. However, previous pathological studies identified MMP-1 and TIMP-1 only in the stroma surrounding thyroid carcinoma. These data suggest that thyroid carcinoma or tumor-associated inflammatory cells might secrete a factor(s) which stimulates MMP-1 or TIMP-1 expression by surrounding tissues. We hypothesized that MMP-1, MT1-MMP, and TIMP-1 would be directly expressed by thyroid carcinoma and might promote invasion or metastasis. We used immunohistochemistry to determine the expression of MMP-1, MT1-MMP, and TIMP-1 in 32 papillary thyroid carcinoma (PTC), 10 follicular thyroid carcinoma (FTC) and 13 benign thyroid lesions from children and adolescents. The intensity of staining was graded from absent (grade 0) to intense (grade 3). Average MMP-1 expression (mean relative intensity units+/-SE) was significantly greater among PTC (1.97+/-0.15; p=0.004) and FTC (2.2+/-0.25; p=0.006) compared to benign lesions (1.30+/-0.15); but there was no relationship between MMP-1 expression and invasion, metastasis, or recurrence. Expression of MT1-MMP and TIMP-1 was similar for benign and malignant lesions; but recurrent PTC expressed lower levels of TIMP-1 when compared to non-recurrent PTC (p=0.049). Only the expression of TIMP-1 correlated with the presence of tumor-associated lymphocytes (r=0.35, p=0.032). We conclude that MMP-1, MT1-MMP and TIMP-1 are all expressed by thyroid carcinoma and could be important in promoting recurrence.

Abstract
OBJECTIVE To describe avoidable mortality in New Zealand, including trends and variations between groups by age, gender, ethnicity and degree of deprivation. METHOD New Zealand Health Information Service mortality unit records, 1981 to 1997, were classified as 'avoidable' or 'unavoidable' based on a reassessment of ICD9 codes and an upper age limit of 75 years. 'Avoidable' causes of death were further subcategorised according to the level of intervention involved (primary, secondary or tertiary). Deaths were assigned a deprivation score using a Census-based small area deprivation index, the NZDep96. Mortality rates were age standardised by the direct method, with Segi's world population as the reference. RESULTS Avoidable mortality declined 38% from 1981 to 1997; unavoidable mortality declined only 9%. In 1996-97 almost 70% of deaths in the 0-74 age range were still considered to be potentially avoidable. Almost 80% of avoidable deaths occur in the 45-74 age group. These deaths are dominated by the emergence of chronic diseases such as ischaemic heart disease, diabetes and smoking-related cancers. In younger age groups, injury (including suicide) dominates avoidable mortality. Males experience a greater burden of avoidable mortality than females--a relative excess of 54% (approximately 2,000) in 1996-97. The gender difference is largely attributable to diseases and injuries amenable to primary prevention, with the largest single contribution coming from ischaemic heart disease. The ethnic gap in avoidable mortality remains wide: rates for Mäori and Pacific people were 2-2 1/2 times higher than European rates in 1996-97. Similar gradients are seen with deprivation. CONCLUSION AND IMPLICATIONS Avoidable mortality analysis provides a useful tool for evidence-based health needs assessment and health policy development.

Abstract
The first child with well-differentiated thyroid cancer treated at the Royal Marsden Hospital presented in 1917. Since that time 30 children under the age of 16 years have been treated over a period during which many new treatments have been introduced. We have reviewed their management and outcome. The median follow-up is 22.5 years (range: 1-66). The median time to recurrence was 7 years (range: 2-44). There were events up to 44 years after presentation. The risk of recurrence was higher in children aged 10 years or younger [HR 3.45, 95% CI (1.04-11.11) P = 0.03]. Thyroid stimulating hormone (TSH) suppression was the only intervention to be shown to reduce the recurrence rate [HR 11, 95% CI (2.27-50) P = 0.0003]. The median overall survival is 53 years. The only presenting feature predictive of poorer survival was the presence of metastases (HR 28.96, 95% CI 2.51-334, P < 0.001). Patients who developed recurrence had a higher risk of death (HR 9.90, 95% CI 0.98-100, P = 0.02) and a shorter median survival of 30 years. No therapeutic intervention could be shown statistically to impact on survival. Our recommendation for treatment is total or near-total thyroidectomy for all patients and radioiodine ablation for all except those with early T stage node-negative disease aged over 10 years. Modified neck dissection is recommended for children with clinically positive neck nodes and TSH suppression for all. Follow-up with serial thyroglobulin measurement should be lifelong.

Abstract
Over the past 22 years, 16 children with thyroid carcinoma were referred to the Northern Israel Oncology Center. All patients had undergone surgical procedures, either total or subtotal thyroidectomy, and 7 patients had undergone cervical lymph node dissections. Postoperatively, 5 patients underwent thyroid ablation with radioactive 131I as first treatment. Two patients received postoperative external radiation therapy to a field encompassing the cervical region, superior mediastinum, and both supraclavicular grooves. After a median follow-up of 60 months (range, 5-169 months), all patients are alive with no evidence of recurrent disease. Two patients who had recurrences, one in the submaxillary lymph nodes and one in the lungs, were salvaged successfully with retreatment with 131I therapy. No severe acute or long-term side effects were exhibited. The long-term results of treatment of pediatric thyroid carcinoma are excellent, but there remains disagreement over the extent of surgical and postsurgical treatment required.
