Abstract
Background. Anaplastic thyroid cancer (ATC) is one of the tumors with the shortest survival in human medicine. Aim. The aim was to determine the importance of age in survival of patients with ATC. Material and Methods. We analyzed the data on 150 patients diagnosed with ATC in the period from 1995 to 2006. The Kaplan-Meier method and log-rank test were used to determine overall survival. Prognostic factors were identified by univariate and multivariate Cox regression analysis. Results. The youngest patient was 35 years old and the oldest was 89 years old. According to univariate regression analysis, age was significantly associated with longer survival in patients with ATC. In multivariate regression analysis, patients age, presence of longstanding goiter, whether surgical treatment is carried out or not, type of surgery, tumor multicentricity, presence of distant metastases, histologically proven preexistent papillary carcinoma, radioiodine therapy, and postoperative radiotherapy were included. According to multivariate analysis, besides surgery (P = 0.000, OR = 0.43, 95% CI = 0.29-0.63), only patients age (P = 0.023, OR = 0.68, 95% CI = 0.49-0.95) was independent prognostic factor of favorable survival in patients with ATC. Conclusion. Age is a factor that was independently associated with survival time in ATC. Anaplastic thyroid cancer has the best prognosis in patients younger than 50 years.

Abstract
AIM To report on two cases of childhood thyroid minimally invasive follicular carcinoma (MIFC) to highlight the clinical features, laboratory findings and diagnosis of this rare disease. METHODS The patients' age, gender, clinical features, laboratory findings, pathology and therapy were reviewed. Immunohistochemistry analysis was performed on the resected masses section. RESULTS From 2000 to 2008, a total of 15 cases of thyroid cancer were confirmed by pathological analysis, which account for about 2.16% of all malignant solid tumours. They included nine of thyroid papillary carcinoma, two of MIFC and one of undifferentiated thyroid carcinoma. For the two children with MIFC, one was an 8-year-boy and one was a 12-year-old girl. Thyroid mass was found as the primary sign. Imaging findings showed well-defined heterogeneous mass and radionuclide scintigraphy with 99mTc demonstrated small cold nodules in the right lobe of thyroid in two cases. Histopathology confirmed the diagnosis of MIFC. Immunohistochemical staining was positive for thyroglobulin, thyroid transcription factor-1, galectin-3, Hector Battifora mesothelial antigen-1, cytokeratin-AE1/AE3, cytokeratin-19, proliferating cell nuclear antigen and E-cadherin in two cases, and S-100 in one case, while CD56, vimentin and desmin were negative. One case was undertaken lobectomy and the other was undertaken subtotal thyreoidectomy with L-T4 replacement therapy. CONCLUSION MIFC is exceedingly rare in children and should be included in the differential diagnosis of thyroid mass. The diagnosis of MIFC depends mainly on the pathological findings.

Abstract
BACKGROUND Anaplastic thyroid carcinoma (ATC) is rare but one of the most aggressive human cancers. It carries a dismal prognosis with average survival of 6 months. It is characteristically diagnosed in patients older than 60 years. We report the case of a young patient with ATC, in whom disease-free survival exceeds 2 years, and review the related literature. SUMMARY A 26-year-old woman presented with a rapidly growing anterior neck mass. A neck computed tomography scan showed a 3.5-cm left thyroid mass extending into the lateral neck. Fine-needle aspiration biopsy showed a malignant tumor. A subsequent core biopsy showed an undifferentiated epithelial carcinoma. A total thyroidectomy and left modified radical neck dissection were performed. Histopathology and immunohistochemical analysis confirmed an ATC. Postoperatively, the patient received radiation with concurrent chemotherapy. Serial follow-up imaging studies showed no evidence of residual or recurrent disease or metastases, and patient remains alive, free of disease, over 2 years. CONCLUSION ATC is usually a disease of the elderly but should be considered in the differential diagnosis of any patient who presents with a rapidly enlarging anterior neck mass. A rapid and thorough investigation should be initiated. This unusual case highlights that this aggressive thyroid cancer may occur in the young. It also emphasizes the role of aggressive surgery, if resectable.

Abstract
Thyroid cancer in children is usually rare, but in the individuals exposed to radiation risk of disease increases considerably. After the Chernobyl accident in 1986, an over 10-fold maximal elevation in the incidence of thyroid cancer was registered about a decade later, cumulatively resulting in more than a thousand of newly diagnosed cases in children who lived in the territories of Belarus, Russia, and Ukraine affected by radioactive fallouts. Experience from the epidemic substantially promoted knowledge in clinical pediatric oncology, pathology and basic sciences. This article overviews epidemiology, clinical features, results of treatment and follow-up of childhood patients with radiation-induced Chernobyl thyroid cancer in comparison to sporadic cases diagnosed at present. In addition, we discuss general issues of pathology and molecular findings in childhood thyroid carcinomas.

Abstract
BACKGROUND/PURPOSE This article is an anatomic, clinical, therapeutic, and prognostic assessment of 56 children 16 years of age or younger, who underwent a surgical operation for thyroid papillary carcinoma from April 1988 to December 2001 in the Department of General Surgery at the University of Pisa. Of these 56 patients, 22 are Belarus children (39%) in whom carcinoma developed after the nuclear accident in Chernobyl in April 1986, whereas 34 (61%) are children with differentiated nonirradiated tumors. The purpose of this work was to compare the group of children who had radiation-induced thyroid carcinoma with the group affected by non-radiation-induced carcinoma to evaluate if there are significant clinical, anatomic, and prognostic differences between them and to identify the best surgical strategy to adopt. RESULTS At the time of clinical presentation, the tumor was limited to the thyroid gland in 28 cases (50%), whereas in the others, in 24 cases (43%) metastases in the neck lymph nodes were present or had infiltrated the extrathyroid tissues as was seen in 4 cases (7%). The surgical operation was a total thyroidectomy in 37 cases (66%), whereas in 19 patients with radiation-induced carcinoma it was a hemithyroidectomy followed by a completion of thyroidectomy in Pisa (34%). The histologic examination showed multifocal sites of papillary adenocarcinoma in the gland in 23% of cases, and both lobes of the thyroid gland were involved with tumor in 23% of patients. The postsurgical follow-up showed a mortality rate of 0% and a recurrence rate of 33.5% (64% radiation-induced carcinoma v 3% non-radiation-induced carcinoma; P < .0001). At the moment, 8 of 22 cases (36%) with radiation-induced carcinoma are free of disease versus 33 of 34 (97%) with non-radiation-induced carcinoma (P < .0001). CONCLUSIONS These findings show carcinoma of the thyroid in children has a low risk of mortality but a high risk of recurrence. Children with radiation-induced thyroid carcinoma are more likely to have a recurrence of the disease. Total thyroidectomy for the treatment of both radiation-induced and non-radiation-induced carcinomas appears to represent, on the basis of these results, the best therapeutic option.

Abstract
Treatment of papillary thyroid carcinoma (PTC) in children and adolescents is controversial. We previously showed that large tumor size, multifocal disease, and extensive disease at diagnosis predict recurrence. We examined 47 patients with PTC to determine whether these features predict response to treatment. Overall, 70% of the patients (33/47) remitted with initial treatment. 79% (15/19), of Class I, 86% (12/14) of Class II, and 100% (6/6) of Class III, but none of Class IV patients (n = 8) (p < 0.001) achieved remission. Tumor size for patients who entered remission (2.0 +/- 0.2 cm) was less than for patients with persistent disease (4.2 +/- 0.4) (p < 0.0005). Extent of disease at diagnosis correlated with the number of radioactive iodine (RAI) treatments (p = 0.022) and dose (p = 0.002) required to achieve first remission. We conclude that extensive disease at diagnosis and larger tumor size predict failure to remit after initial treatment of PTC in children and adolescents.

Abstract
BACKGROUND The optimal surgical treatment in children with well-differentiated thyroid carcinoma remains an important point of discussion. In this study, we evaluated our surgical experience and reviewed the literature accordingly to identify the most adequate treatment. METHODS We retrospectively analyzed 21 children, all under the age of 18 years at the time of diagnosis, with differentiated thyroid carcinoma (17 papillary, 3 follicular, and 1 Hürthle cell carcinoma). Total thyroidectomy was performed, followed by radioiodine therapy, as a part of the initial treatment in all patients. The results were compared with data from the literature. RESULTS Eleven children (52%) who presented with cervical lymph node metastases were treated by a modified radical neck dissection. Pulmonary metastases were seen at diagnosis in three patients. Six patients developed temporary complications. During follow-up, with a median of 11 years (range, 2-26 years), two patients (10%) developed recurrences, and no patient died during this observation period. A literature search confirmed our experience of excellent results without an increase of complications in the more aggressively treated patients. CONCLUSIONS In children with differentiated thyroid cancer, treatment should consist of total thyroidectomy, followed by a modified radical neck dissection (when indicated) and iodine-131 ablation treatment. This aggressive approach seems to be justified because of the high incidence of nodal involvement and the low complication and recurrence rate after surgery.

Abstract
OBJECTIVES This analysis was performed to evaluate the influence of clinical and treatment factors on local tumor control, control of distant metastasis, survival, and complications in children and adolescents with thyroid carcinoma. METHODS The records of 56 children and adolescents with papillary and follicular carcinoma of the thyroid were reviewed. They ranged in age from 4 to 20 years. There were 43 females and 13 males. At diagnosis, 15 (27%) patients had disease confined to the thyroid, 34 (60%) had additional lymph node metastasis to the neck or upper mediastinum, and 7 (13%) also had lung metastasis. Treatment consisted of a total thyroidectomy in 48 patients, a subtotal thyroidectomy in 4 patients, and a lobectomy in 4 patients. All 56 patients received postoperative thyroid hormone suppressive therapy. (131)I was administered to 82% (46 of 56) of patients after their initial surgery. RESULTS The overall survival rate was 98% with a follow-up of 0.6-30.7 years (with a median follow-up of 11.0 years). The one death that occurred in this patient population was the result of a congenital heart defect and was unrelated to thyroid carcinoma. The 10-year progression-free survival rate was 61%. Nineteen patients (34%) experienced a recurrence of their thyroid carcinoma. The time to first recurrence of disease ranged from 8 months to 14.8 years (mean, 5.3 years). None of those with disease confined to the thyroid developed recurrent disease. The recurrence rate was 50% (17 of 34) in patients with lymph node metastasis and 29% (2 of 7) in patients with lung metastasis (P = 0.02). Tumor characteristics were evaluated for time to first recurrence utilizing the logistic likelihood ratio test to predict disease recurrence. Thyroid capsule invasion (P = 0.02), soft tissue invasion (P = 0.03), positive margins (P = 0.006), and tumor location at diagnosis (thyroid only vs. thyroid and lymph nodes vs. thyroid, lymph nodes, and lung metastasis, P = 0.02) were significant for developing recurrent disease. Patients younger than 15 years old at diagnosis were more likely to have more extensive tumor at diagnosis than patients who were 15 years and older (thyroid only vs. thyroid and lymph nodes vs. thyroid, lymph nodes, and lung metastasis, P = 0.02). CONCLUSION Carcinoma of the thyroid in children and adolescents has little risk of mortality but a high risk of recurrence. Younger patients present with a more advanced stage of disease and are more likely to have disease recurrence. Total thyroidectomy and lymph node dissection, followed by postoperative (131)I therapy, thyroid hormone replacement (suppressive) administration, and diligent surveillance are warranted.

Abstract
BACKGROUND Sporadic well-differentiated thyroid cancer is an uncommon condition in children, adolescents, and young adults. It is associated with distinct clinicopathologic features and prognosis. The present study reviews our experience in management of this condition in ethnic Chinese in Hong Kong. STUDY DESIGN A retrospective study was performed to review the clinicopathologic features and outcomes of 34 patients less than 21 years of age with well-differentiated thyroid carcinoma over a 35-year period. Median followup was 15.2 years (range 1 to 32.5 years). RESULTS There were 27 girls and 7 boys with a median age of 19 years (range 10 to 21 years). None had previous history of irradiation. Twenty-eight patients had papillary and six had follicular carcinomas. Operative procedures included total thyroidectomy (n = 27) and unilateral lobectomy (n = 7) with concomitant neck dissection performed in nine patients. The median tumor size was 2 cm and extrathyroidal invasion was present in 19 tumors. Adjuvant radioactive iodine treatment was administered to 18 patients after total thyroidectomy. Disease progression or recurrence rate was 24% and 27% at 5 and 10 years, respectively. The presence of lymph node metastases was associated with a higher incidence of disease recurrence. One patient with advanced local disease died from tumor bed recurrence with anaplastic transformation 18 years after the initial operation. CONCLUSIONS Well-differentiated thyroid carcinoma is a relatively indolent tumor associated with good prognosis in young patients. Although death from this condition is rare, recurrence is frequent and longterm followup is necessary.

Abstract
BACKGROUND Children with papillary thyroid cancer (PTC) rarely die of their disease, but are at high risk for recurrence, particularly with multifocal tumors (which occur in 42% of children with PTC). It is not clear if more extensive surgery, with an increased risk of complications, lessens the risk for recurrence. The authors hypothesized that patients with disease presumed to be confined to the thyroid gland (class I PTC) could have multifocal disease, involving the contralateral lobe, of which the surgeon is unaware. Treatment with less than subtotal thyroidectomy might be associated with a higher risk of recurrence. METHODS The charts of 37 patients with Class I PTC diagnosed at < or =21 years of age between 1953 and 1996 were reviewed. The incidence of surgical complications and the risk of recurrence based on the extent of initial surgery ([1] lobectomy with or without isthmusectomy, [2] subtotal, or [3] total thyroidectomy) and adjunctive therapy with thyroid hormone or radioactive iodine (RAI) were examined. RESULTS Eight patients had recurrent PTC. Patients treated with lobectomy with or without isthmusectomy were more likely to have recurrence than patients treated with subtotal or total thyroidectomy (Odds ratio, 8.7; 95% CI 1.4 to 54). Although the incidence of complications was statistically similar among the 3 surgical groups, 3 patients, all treated with more extensive surgery, had permanent hypoparathyroidism. There were too few patients to determine whether treatment with thyroid hormone or RAI offered additional benefit. CONCLUSIONS In children with Class I PTC, more extensive surgery is associated with a lower risk of recurrence. This finding must be weighed against the risk of complications when determining the optimal treatment for individual patients.

Abstract
OBJECTIVE Differentiated thyroid cancer (DTC), including papillary (PTC) and follicular (FTC) variants, is unusual in children and accounts for only 10% of all cases. For that reason, knowledge of the clinical features which predict recurrence is limited. We reviewed 170 cases of childhood DTC to determine if specific clinical or pathological findings were associated with increased risk of recurrence. DESIGN This was a retrospective study of children and adolescents with DTC registered in the Department of Defense Automated Centralized Tumor Registry. PATIENTS We reviewed 137 cases of PTC and 33 cases of FTC diagnosed between 1953 and 1996 at < or = 21 years of age. RESULTS In the PTC group (median follow-up 6.6 years, range 2 month-39.5 years), only one patient died, but 21 developed local and 6 developed distant recurrence. By univariate analysis, recurrence was more common in patients with multifocal (odds ratio 7.5) or large tumours (odds ratio 4.1), and in those with palpable cervical lymphadenopathy (odds ratio 3.0) or metastasis at diagnosis (odds ratio 2.8). By multivariate analysis focality was the best predictor of recurrence (P = 0.0019). In the FTC group (median follow-up 5 years, range 6 month-38.1 years), no patient died of disease, but 5 developed recurrence. As with PTC, recurrence was more likely in patients with multifocal tumours (odds ratio 22.0). CONCLUSIONS Differentiated thyroid cancer in children and adolescents has low mortality, but a high risk of recurrence. Young patients with large, multifocal tumours that are already metastatic at diagnosis have the greatest risk of recurrence.

Abstract
OBJECTIVE This study was done to define the extent of disease and evaluate the effect of staging and treatment variables on progression-free survival in patients with differentiated thyroid carcinoma who were less than 21 years of age at diagnosis. SUMMARY BACKGROUND DATA Differentiated thyroid cancer in young patients is associated with early regional lymph node involvement and distant parenchymal metastases. Despite this, the overall long-term survival rate is greater than 90%, which suggests that biologic rather than treatment factors have a greater effect on outcome. METHODS Variables analyzed for their impact on progression-free survival in a multi-institutional cohort of 329 patients included age, antecedent thyroid irradiation, extrathyroidal tumor extension, size, nodal involvement, distant metastases, technique of thyroid surgery and lymphatic dissection, initial treatment with 131Iodine, residual cervical disease, and histopathologic subtype. Surgical complications were correlated with the specific procedures completed on the thyroid gland or cervical lymphatics. RESULTS The overall progression-free survival rate was 67% (95%, CI: 61%-73%) at 10 years with 2 disease-related deaths. Regional lymph node and distant metastases were present in 74% and 25% of patients, respectively. Progression-free survival was less in younger patients (p = 0.009) and those with residual cervical disease after thyroid surgery (p = 0.001). Permanent hypocalcemia was more frequent after total or subtotal thyroidectomy (p = 0.001) while wound complications increased after radical neck dissections (p < 0.00001). CONCLUSIONS The progression-free survival rate was better after a complete resection and in older patients. Progression-free survival rate was the same after lobectomy or more extensive thyroid procedures, but comparison was confounded by the increased use of total or subtotal thyroidectomy in patients with advanced disease. The risk of permanent hypocalcemia increased when total or subtotal thyroidectomy was done. Thyroid lobectomy alone may be appropriate for patients with small localized lesions while total or subtotal thyroidectomy should be considered for more extensive tumors.

Abstract
In the thirty year period between 1966 and 1996, fifty-two patients underwent surgery for thyroid nodules at the Royal Children's Hospital, Melbourne. We aimed to review their presentation, investigation, histology, treatment and to follow up those who had malignant neoplasms. Forty-one of the fifty-two patients presented with a single thyroid nodule. Investigations performed included thyroid function tests (N = 32), thyroid autoantibodies (N = 21), an ultrasound of the thyroid (N = 26) and 99mTechnetium scanning (N = 32). Thirty-five of the neoplasms were benign, the follicular adenoma (N = 16) being the most common. Seventeen patients had malignant neoplasms, seven of whom had papillary and seven of whom had follicular carcinoma. Three patients had medullary carcinoma of the thyroid. Nine of the seventeen patients with thyroid malignancy received post-operative 131I treatment. At the time of this review, all patients were living.
