Abstract
From 1956 to 1975 21 patients (13 females and 8 males) with thyroid cancer developed by age 14 have been observed at the Istituto Nazionale Tumori of Milan. Follicular adenocarcinoma was diagnosed in 4 cases and papillary adenocarcinoma in 17. Five patients (24%) had been given previous cervical irradiation for benign conditions. At admission lung metastases were evident in 2 patients (one affected by follicular and the other by papillary adenocarcinoma). All patients were submitted to surgical treatment, which in most cases consisted in total thyroidectomy plus elective lymph node dissection; serious postoperative complications were not observed. External irradiation was given to 4 patients, since surgery had not been radical. Radioiodine treatment was performed in the 2 patients with lung metastases: in the patient with follicular adenocarcinoma metastases disappeared after 131I treatment, whereas in the other one they still persist unmodified 10 years later. A local recurrence occurred in 3 cases and pulmonary metastases in one: all of them made an apparent recovery after surgical and/or radioiodine treatment. All patients are alive and, except one, without evidence of disease after a follow-up period from 14 months to 21 years. Although differences in evolution have been noted according to the histotype, the prognosis of thyroid cancer in childhood is good, evenif distant metastases are present.

Abstract
OBJECTIVE The retrospective analysis of the case files of children with differentiated thyroid carcinoma (DTC) was performed to define the disease by its presentation, clinical course and outcome of radioiodine therapy. METHODS Between 1967 to October 2002, 1754 patients with thyroid cancer were treated in the Dept of Neuclear Medicine, AIIMS, out of which 122 (7%) were < or = 20 years of age (71 girls and 51 boys). The mean age was 15.8 +/- 3.6 years and the mean duration of follow-up was 90 +/- 59.3 months. Mean tumor size was 4.4 cm. Histologically, 85% of the patients had papillary and rest follicular carcinoma. Cervical lymph node involvement was seen in 64%, and distant metastases, mainly pulmonary, in 23% of the patients. The presentation of the disease was very aggressive in the first decade of life with male preponderance. All but one patient in this age group had nodal and/or distant metastases; in 83.3% the disease had spread to the lymph nodes and 67% had metastases to the lungs. The post-surgery 48-hour mean radioiodine neck uptake was 10.5 +/- 7.6%. RESULTS 94% of the residual thyroid, 88% of nodal metastases and 71% of pulmonary metastases were ablated requiring mean cumulative doses of 2.8 +/- 2.7 GBq, 4.5 +/- 2.7 GBq and 10.4 +/- 7.9 GBq of 131I, respectively. Average number of doses required for remnant, nodal and pulmonary metastases ablation were 1.3, 2.2 and 3.3, respectively. 80% of the patients with only remnant thyroid tissue and 50% with cervical lymph node metastases got ablated with a single dose of 131I. Overall, 87% patients were currently free of disease. While, nine patients had nodal recurrence between surgery and radioiodine treatment, no recurrence was observed thereafter and 3 disease related deaths producing overall mortality of 2.5% (all in children < or =10 years of age) were seen in the mean follow-up of 7.5 years. CONCLUSION Differentiated thyroid cancer in children and adolescents is rare but aggressive. The biological behavior differs from that in adults and is related to the age. Younger the age (< or =10 years), more aggressive and widespread is the disease with male preponderance and high mortality. The post-surgical radioiodine ablation/therapy is an important and effective adjuvant in the management of DTC in children and adolescents and even though they present with advance disease, long-term survival and overall prognosis is good.

Abstract
OBJECTIVE To evaluate DNA ploidy in papillary thyroid carcinoma in children in correlation to the clinical course of the disease. METHODS Flow cytometric DNA ploidy measurements were performed on formalin-fixed, paraffin-embedded tumor specimens from 14 children and 14 adult patients with papillary carcinoma of the thyroid gland. Analysis of DNA content was performed blind to patient's age and clinical presentation. RESULTS Seven patients presented with cervical metastasis, one patient had distal metastasis and four patients had local invasion. All patients underwent total thyroidectomy. Seven children underwent bilateral modified neck dissection. Twenty-five tumors expressed diploid DNA content. No statistically significant difference in DNA content was observed between the tumors from child and adult patients. No correlation was found between DNA content and aggressive presentation in the pediatric group. CONCLUSION Our primary results indicate that diploid DNA content is common in papillary thyroid carcinoma in children and aggressive clinical presentation is not associated with DNA aneuploidy. Larger prospective studies and long-term clinical follow-up is warranted to document the clinical significance of these observations.

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
BACKGROUND Cervical lymph node metastasis in differentiated thyroid carcinoma has mostly been found to have little relationship to prognosis. However, some studies report nodal involvement to be an adverse factor, while others have found it to be favorable. We have undertaken a matched-pair analysis of previously untreated patients, with and without ipsilateral neck metastasis, to examine the significance of nodal spread in patients with otherwise equivalent prognostic factors for differentiated thyroid cancer. METHOD From a database of 931 patients, treated from 1930 to 1980, we used a computer to match patients with confirmed lateral neck metastasis (N1) to those who were stage NO, and had the following identical prognostic factors: no distant metastasis, age (within 4 years), and tumor size, histology, and intrathyroidal extent. When possible, matches were also made for gender, multifocality, and extent of thyroid surgery. Survival and treatment failures were analyzed, with and without stratification for age. RESULTS We were able to select 100 N1 patients with corresponding NO patients, sharing the major prognostic risk factors as listed. Overall, there was no difference in survival, although N1 patients more often had recurrence. Mortality increased with age. Analysis at high-risk age (45 years and older) showed significantly more recurrences in N1 patients (p = .008). Twenty-year survival in N1 patients over the age of 45 was lower than that of NO patients. On the other hand, under the age of 45, N1 patients had better survival. These differences, however, did not reach statistical significance. CONCLUSION Nodal involvement in older patients with thyroid cancer increases the risk of recurrence, although no significant difference in survival is observed in relation to age.

Abstract
Between 1974 and 1993 ten girls and six boys aged 6-16 years underwent total thyroidectomy, with therapeutic selective neck dissection in six patients. All were treated after operation with radioactive iodine (131I) for ablation of thyroid tissue remnants. Papillary carcinoma occurred in ten patients, follicular carcinoma in two and medullary thyroid lesions in four. The patients were followed for a median of 11.5 (range 1-20) years with regular determinations of serum thyroglobulin levels and 131I whole-body scanning when indicated. Only one patient had a slight increase in thyroglobulin levels without evidence of disease on further screening. In children with medullary lesions the serum levels of basal and pentagastrin-stimulated calcitonin remained normal. Currently all patients are alive and without disease. Hypocalcaemia lasting for more than 1 year was observed in one patient. Recurrent nerves were not injured accidentally, but because of tumour invasion two of 32 recurrent nerves had to be sacrificed. This surgical approach is safe and well tolerated in children.

Abstract
A 16-year-old girl presented with a palpable thyroid nodule which was found to be functioning autonomously by radioiodine (123I) scintigraphy. After needle biopsy proved non-diagnostic, surgical excision showed the nodule to be Hürthle cell carcinoma. Functional thyroid nodules are rarely malignant, thyroid carcinoma is rare in childhood, and Hürthle cell carcinoma is a rare thyroid neoplasm, so the presence of these three rare conditions in one patient makes it a very unusual case.

Abstract
BACKGROUND During the initial period after the Chernobyl accident, large amounts of radioactive iodine were released in fallout, resulting in serious exposure to the thyroid gland in the residents of areas around the nuclear power station. Beginning in 1990, a definite increase in the incidence of thyroid cancer was noted in children of the Republic of Belarus. METHODS Morphologic and clinical features of 84 cases of post-Chernobyl thyroid carcinoma in Belarussian children from 5 to 14 years of age are reported. The latent period for tumor development was 4-6 years, with a mean of 5.8 years. RESULTS Papillary carcinoma was found in 83 patients and medullary carcinoma in one. Besides typical papillary carcinoma (14%), solid (34%), follicular (33%), mixed (10%), and diffuse sclerosing (9%) variants were observed. The follow-up period ranged from 8 months to 2.5 years. One patient died, local recurrence developed in 2, and cervical lymph node metastases developed in 10. To date, the incidence of local recurrence or metastatic disease after surgery was significantly higher in patients 5-8 years of age and in residents of areas nearest to the Chernobyl station. CONCLUSIONS Post-Chernobyl pediatric thyroid carcinoma is characterized by a short latency, a higher proportion of tumors arising in young children, and an almost equal sex ratio. Microscopically, these tumors were usually aggressive, often demonstrating intraglandular tumor dissemination (92%), thyroid capsular and adjacent soft tissue invasion (89%), and cervical lymph node metastases (88%). Papillary carcinoma was diagnosed in 99% of cases, with an unusually high frequency of solid growth patterns. Morphologic changes in nonneoplastic thyroid tissue were present in 90% of the glands, and the most specific findings were vascular changes and perifollicular fibrosis.

Abstract
Twenty-three children and adolescents with thyroid carcinoma who were 20 years old or younger at the time of initial treatment were followed for a mean time of 9.5 years. Of the tumours, 21 were papillary and two follicular carcinomas. The majority (91%) of the 23 cases showed extra-thyroidal extension of the tumour. An association with chronic thyroiditis was observed in 30% of the cases. There was no history of irradiation of the head and neck in any patients. Relapse occurred in eight patients, lung metastases in two and local recurrences in six; one patient died from lung metastases 3 months after initial treatment. Male patients, advanced stage of tumour, less differentiated histological features and DNA aneuploidy were associated with a higher frequency of relapse. The prognosis of thyroid carcinomas in children and adolescents is not so good as is generally believed.

Abstract
An analysis of differentiated thyroid carcinomas in children and adolescents revealed that the incidence was 3.05% of total number of patients with differentiated thyroid cancers in all age groups. There was a female preponderance. The incidence of papillary, follicular and papillary with follicular elements was equal. There were no papillary carcinomas observed in children younger than 10 years. The predominant mode of presentation was a solitary nodule of thyroid and some of them had associated cervical adenopathy. A considerable number presented with only cervical adenopathy. The incidence of nodal metastases was 50% at time of presentation and lung involvement was present in 15% of children at the time of diagnosis. Radioiodine treatment was given in 70% of children. Ablation was achieved in 86% of patients given two doses of radioiodine (200 millicuries). The more resistant cases were those with lung and nodal metastases. There was complete ablation in 100% with only residual thyroid tissue, 83% in those with associated nodal metastases, and 57% in those with lung involvement. Average duration of follow-up was 10.3 years (range, 2 to 19 years). Recurrence rate or relapse was observed in 8.5% and was in the regional nodes. There was no recorded mortality due to the disease.

Abstract
A total of 117 patients under 20 years of age with papillary and/or follicular thyroid cancer presented to the M. D. Anderson Cancer Center between 1949 and 1987. The most common presenting symptom was a cervical mass. Twenty percent of the patients had a history of prior irradiation. Sixty percent initially had palpable lymph nodes, while 26% who had clinically negative examinations had pathologically positive lymph nodes. Recurrence was highest in regional lymph nodes at 24%, with only a 4% recurrence rate at the primary site and a 3% recurrence rate at distant sites. There were no deaths due to the thyroid cancer. To maintain a low rate of recurrence, near-total thyroidectomy with neck dissection followed by iodine 131 treatment should be considered in these young patients.

Abstract
During a 10 year period, 1971-80, there were 234 children in Great Britain younger than 15 years with a diagnosis of carcinoma registered in Great Britain. These cases represented approximately 2% of all childhood malignant disease. The most common primary site was the thyroid, followed by the nasopharynx and the adrenal cortex. With the exception of adrenocortical tumors, most of the carcinomas occurred in children older than 10 years. In some patients there was a genetic predisposition to neoplasia. Children with carcinomas of the thyroid and female genital tract have an excellent prognosis with 5-year survival rates of over 90%. The prognosis for other sites was generally less favorable; 60% of children with nasopharyngeal tumors were alive at 5 years from diagnosis but less than 20% of those with carcinomas of the gastrointestinal tract or the adrenal cortex.

Abstract
Fifteen patients, 11 females and 4 males, aged 4-16 years with follicle-derived differentiated thyroid carcinoma treated at the Helsinki University Central Hospital during 1953 through 1984 are reported. Histologically 13 carcinomata were papillary, 1 follicular and 1 was suspected to be follicular carcinoma (atypic adenoma). Eleven (73%) had cervical lymphnode metastases and 4 (25%) pulmonary metastases as well. All patients were initially operated on; total thyroidectomy was performed in 11 and subtotal in 4 patients. In 5 patients there was invasion into the thyroid capsule, perithyroid tissues and blood vessels; 4 patients with pulmonary metastases belonged to this group. Postoperatively 5 patients received radioactive iodine, 4 patients external irradiation to the neck and 6 were given both types of radiation. Pulmonary metastases were treated with radioactive iodine. The patients have been given suppressive doses of thyroxine. The follow-up ranged from 3.5 to 33 years. One patient with extensive pulmonary metastases died 6 years after the initial treatment, all others are still alive. Twelve patients have been followed for 9 to 33 years, in 10 serum thyroglobulin was determined. Tg was undetectable in 9 patients when measured during thyroxin therapy; in 1 patient followed for 33 years, the dose was not suppressive, and there were no signs of disease and Tg in the normal range. In 2 patients Tg could not be determined but they had no signs of disease 18 and 22 years after initial treatment. It is, therefore, presumed that these patients, forming 80% of the material, are cured. Two patients followed for 3.5 years are still under treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Eleven cases of thyroid cancer occurring in patients below 15 years of age are presented. The youngest patient was 4 years old. There were 4 boys and 7 girls in the study group. None of the patients had received head and neck irradiation. All patients had well differentiated cancers; there were 4 follicular carcinomas and 3 of these occurred in patients below 10 years of age. Six patients presented with solitary thyroid nodules. Lymph node involvement had occurred in 63.7% of cases. One patient presented with CNS metastasis. Treatment aimed at near total thyroidectomy was performed in 9 patients. Two patients died of the disease during the follow up period and another 3 patients are alive. Postoperatively radioactive iodine was routinely used for evaluating and treating residual and recurrent disease.

Abstract
Differentiated thyroid cancer in children remains a controversial disease entity. Its incidence has markedly declined over the last decade since the use of radiotherapy in the treatment of benign conditions of the head, neck, and thorax was abandoned. Other etiologic factors have become relatively more important. The clinical presentation of childhood thyroid cancer is similar to that found in adults, except for a higher frequency of local and distant metastases at the time of initial diagnosis. The specificity and sensitivity of diagnostic tests are limited; however, like in adults, fine-needle aspiration compares favorably with other available diagnostic methods. The therapeutic approach to a child with thyroid cancer represents the most controversial issue associated with the disease. This review provides a discussion of the rationale for the different therapeutic options and emphasizes the excellent prognosis and survival rates, especially when patients are subjected to aggressive treatment with total thyroidectomy followed by the administration of radioactive iodine.

Abstract
Thyroid cancer encompasses some forms that practically have no identifiable mortality to one of the most lethal soft tissue cancers known. Because of this variation, a knowledge of the role that age, histology, and extent of disease play in establishing a prognosis is necessary to provide a rational therapeutic program. Younger patients (under age 40) with differentiated cancer, even those with lymph node metastases, should not be overtreated with extensive surgery and 131I or external beam therapy because the prognosis in these patients is so extremely good. Thyroid hormone suppression is probably adequate therapy for patients in this group after obvious disease has been resected. Recurrences can usually be effectively treated with 131I. On the other hand, older patients should be treated more aggressively, especially with the routine use of 131I ablation and therapy after resection of disease. Radiation therapy as described for recurrent disease should be considered at an early point and should be used immediately once the diagnosis of anaplastic cancer has been established. Finally, patience and observation alone should be considered a good therapeutic alternative, for example, in hypercalcitoninemic patients with medullary cancer that has been apparently adequately resected. Repeat operations in these patients fail to eliminate elevated serum calcitonin levels in the majority of cases, and the patients may live for many years with a good quality of life.

Abstract
Diffuse thyroid enlargement in a child is a rare presenting symptom of thyroid carcinoma. A papillary carcinoma may be hidden in a diffuse lymphocytic thyroiditis and should be carefully searched for during surgery. Furthermore, the finding, in frozen sections, of psammoma bodies in a lymphocytic thyroiditis should raise the suspicion of an occult malignant neoplasm. A case illustrating these diagnostic difficulties in a 5-year-old child is presented.

Abstract
A patient with previously treated follicular carcinoma of the thyroid developed Graves' disease with a high titre of thyroid-stimulating antibodies (TSAb). He developed functioning pulmonary metastases leading to hyperthyroidism. Levels of TSAb paralleled the functional status of the metastases suggesting that hyperfunction of the neoplastic tissues was caused by TSAb.

Abstract
Thyroid cancer in childhood is a relatively rare condition. Often it shows biological characteristics different from those seen in adults. Based upon 10 cases in our clinic and 57 cases collected from the Japanese literatures, clinical features, pathology, treatment and prognosis of thyroid cancer in childhood are discussed. Pathogenesis is most likely to be related to hormonal changes during adolescence and previous radiation of the neck region. Cervical lymph nodes swelling was the chief complaint in 84.6 per cent of the cases. On the other hand, pulmonary metastases were recognized in the early stages in 33.5 per cent of the cases. Radical excision of the tumor with modified radical neck dissection is the treatment most frequently employed even in the presence of lung metastases. However, hypoparathyroidism and recurrent nerve injuries should be avoided at all cost in view of long life expectancy and the difficulty in treating them satisfactorily. Prognosis could be as good for children as it is for adults except in cases with early lung metastases.

Abstract
Malignant neoplasms of the thyroid gland are quite rare in children. Winship, in his classic article, could find only 562 cases in the literature. The histopathological patterns resemble those of the adult tumors. Despite early cervical metastasis, the prognosis in general is favorable, with many long-term survivals. Prior exposure to radiation of the head and neck is a definite pre-disposing factor. Teratomas of the neck are a medical curiosity--less than 100 cases are described in the literature. The vast majority of these are found during the neonatal period, and are benign histologically. These are usually large, cystic, bulky masses which produce mechanical obstruction of the upper airway and digestive tract. Only one of these tumors, described by Pupovac in 1896, has been considered malignant. A six-year-old child was examined with a right thyroid mass of three months' duration. The thyroid scan showed a "cold nodule." At surgery, a well-encapsulated mass was found. The pathology showed a predominance of malignant spindle cells, with areas of papillary carcinoma; however, there were well-defined mucous glands present in the tumor. Clinically the child has remained well and asymptomatic. The slides have been extensively reviewed. To my knowledge no such tumor has been previously described. The tumor is considered to be a malignant thyroid tumor growing out of teratomatous tissue.

Abstract
These relatively infrequent tumors intrigue both clinican and researcher. Each histologic type posesses its own distinctive natural history, controversy surrounds therapeutic programs, and prognosis is influenced by multiple factors, varying from a fatal outcome within a few months to a nearly normal life expectancy. Since fatalities do occur in patients with well differentiated cancers, a more aggressive approach to all thyroid nodules would improve current survival rates.

Abstract
Abstract
Recent collective experience with thyroid cancer in children in Britain is reported. Fifteen out of 16 patients with papillary carcinoma treated in the years 1962–7 are still living at least 5–10 years later; the sixteenth patient died of an unrelated cause. Two patients with follicular carcinoma also survived. Seven deaths between 1957 and 1970 were due to anaplastic or medullary carcinomas and 1 death was caused by a papillary carcinoma.
These data emphasize that in the treatment of papillary carcinoma we should take account of its prolonged natural history. Radical operations which have serious associated morbidity do not appear to be indicated.
