Abstract
PURPOSE A cross sectional study of adolescent and young adult (AYA) head and neck (H&N) cancer survivors was performed to assess late effects. Survivorship care plans (SCPs) were generated and evaluated by participants and their primary care providers (PCPs). METHODS AYA H&N survivors who had been discharged over 5 years prior from our institution were assessed in recall consultation by a radiation oncologist. Late effects were assessed and individualized SCPS were created for each participant. Participants completed a survey evaluating the SCP. PCPs were surveyed before the consultation and after evaluating the SCP. RESULTS 31/36 participants (86%) completed the SCP evaluation. The SCP was considered to be a positive experience for 93% of participants. Most of the AYA participants indicated that the information provided in the SCP helped them understand the need for follow-up to assess late effects (90%). The pre-consultation PCP survey response rate was 13/27 (48%) and only 34% were comfortable in providing survivorship care for AYA H&N cancer patients. The PCP response rate to the survey that accompanied the SCP was 15/27 (55%) and the majority (93%) reported that the SCP would be helpful to care for other AYA and non-AYA cancer survivors in their practice. CONCLUSIONS Our research suggested that AYA head and neck cancer survivors valued the SCPs as did their PCPs. IMPLICATIONS FOR CANCER SURVIVORS The introduction of SCPs is likely to help improve survivorship and transitioning of care from the oncology clinic to PCP in this population.

Endocrine Late Effects in Childhood Cancer Survivors. Cancers (Basel) 2022; 14:cancers14112630. [PMID: 35681610 PMCID: PMC9179858 DOI: 10.3390/cancers14112630] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 05/10/2022] [Accepted: 05/12/2022] [Indexed: 11/17/2022] Open
Abstract
Simple Summary Recent advances in cancer treatment have led to improved survival, with an exponential increase in sequelae among survivors. Around 50% of survivors will experience at least one hormonal disorder, with radiotherapy, hematopoietic stem cell transplantation, and alkylating chemotherapy being the most frequently related. Therefore, lifelong monitoring of childhood cancer survivors at risk is paramount. With this review, we describe in detail the most prevalent endocrine sequelae, considering new approaches such as proton beam therapy and immune-related endocrinopathies with the advent of precision oncology treatment. We hope to encourage oncologists and endocrinologists to develop early detection guidelines that minimize sequelae and have a positive impact on their quality of life. Abstract Childhood cancer management has improved considerably over the years, leading to a significant improvement in survival of up to 80%. However, childhood cancer survivors are at the highest risk of developing sequelae resulting from treatment, with endocrine complications being frequently observed among survivors. Multiple predisposing factors for endocrine sequelae have been identified, including age at diagnosis, treatment received, radiation, tumor type, and genetic polymorphisms, which could explain the individual predisposition to develop drug toxicity. Novel agents targeting tumor growth and immune checkpoint inhibitors have recently become the cornerstone for the treatment of different cancers, triggering a myriad of immune-related endocrinopathies. Endocrine sequelae of cancer therapy will have an impact on not only childhood but also on the survival and quality of life of these highly complex patients. Therefore, lifelong monitoring of childhood cancer survivors at risk of endocrine diseases is paramount. Encouraging oncologists and endocrinologists to develop new follow-up and early detection guidelines that minimize sequelae among these patients has become a priority, promoting integration between pediatric and adult units since many sequelae may manifest only after years to decades of follow-up.

Abstract
PURPOSE Adolescent and young adult (AYA) head and neck (H&N) cancer survivors are at risk of long-term complications. A cross-sectional study of survivors recalled for clinical evaluation was performed to evaluate late effects in this population. METHODS Surviving patients who had been diagnosed with H&N cancer between the ages of 15 and 39 years and treated with radiation therapy (RT) in British Columbia between 1970 and 2010 were invited to participate in this study. Survivors were assessed in consultation by a radiation oncologist for a complete history and physical exam. Comprehensive data collection of subjective and objective late effects of RT and screening investigations were completed. RESULTS Of 36 AYA H&N participants, the majority were female (61%), and the most common tumour sites were thyroid (28%), oropharynx (17%), salivary gland (14%) and larynx (14%). Dental extractions post treatment was performed for 33% and dental implants for 17%. The majority (72%) reported xerostomia, 50% had dysphagia to solids and 25% hearing loss. Of the non-thyroid cancer patients who underwent RT to their neck, 45% developed hypothyroidism. There were 28% of participants with asymptomatic carotid stenosis and 27% with thyroid nodules; all were diagnosed after recall screening. CONCLUSIONS Survivors of AYA H&N cancer treated with RT reported numerous long-term complications. Comprehensive follow-up and screening guidelines should be established for this at-risk population. IMPLICATIONS FOR CANCER SURVIVORS AYA H&N cancer survivors and their primary care practitioners should be educated on screening recommendations and the risk of late effects.

Screening for thyroid cancer in survivors of childhood and young adult cancer treated with neck radiation. J Cancer Surviv 2017; 11:302-308. [PMID: 28028762 PMCID: PMC5527324 DOI: 10.1007/s11764-016-0588-6] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2016] [Accepted: 12/04/2016] [Indexed: 12/17/2022]
Abstract
BACKGROUND The optimal method of screening for thyroid cancer in survivors of childhood and young adult cancer exposed to neck radiation remains controversial. Outcome data for a physical exam-based screening approach are lacking. METHODS We conducted a retrospective review of adult survivors of childhood and young adult cancer with a history of neck radiation followed in the Adult Long-Term Follow-Up Clinic at Memorial Sloan Kettering between November 2005 and August 2014. Eligible patients underwent a physical exam of the thyroid and were followed for at least 1 year afterwards. Ineligible patients were those with prior diagnosis of benign or malignant thyroid nodules. RESULTS During a median follow-up of 3.1 years (range 0-9.4 years), 106 ultrasounds and 2277 physical exams were performed among 585 patients. Forty survivors had an abnormal thyroid physical exam median of 21 years from radiotherapy; 50% of those with an abnormal exam were survivors of Hodgkin lymphoma, 60% had radiation at ages 10-19, and 53% were female. Ultimately, 24 underwent fine needle aspiration (FNA). Surgery revealed papillary carcinoma in seven survivors; six are currently free of disease and one with active disease is undergoing watchful waiting. Among those with one or more annual visits, representing 1732 person-years of follow-up, no cases of thyroid cancer were diagnosed within a year of normal physical exam. CONCLUSIONS These findings support the application of annual physical exam without routine ultrasound for thyroid cancer screening among survivors with a history of neck radiation. IMPLICATIONS FOR CANCER SURVIVORS Survivors with a history of neck radiation may not require routine thyroid ultrasound for thyroid cancer screening. Among adult survivors of childhood and young adult cancer with a history of radiation therapy to the neck, annual physical exam is an acceptable thyroid cancer screening strategy.

Abstract
During the past few decades, the incidence of thyroid cancer has increased substantially in many countries, including the USA. The rise in incidence seems to be attributable both to the growing use of diagnostic imaging and fine-needle aspiration biopsy, which has led to enhanced detection and diagnosis of subclinical thyroid cancers, and environmental factors. The latest American Thyroid Association (ATA) practice guidelines for the management of adult patients with thyroid nodules and differentiated thyroid cancer differ substantially from the previous ATA guidelines published in 2009. Specifically, the problems of overdiagnosis and overtreatment of a disease that is typically indolent, where treatment-related morbidity might not be justified by a survival benefit, now seem to be acknowledged. As few modifiable risk factors for thyroid cancer have been established, the specific environmental factors that have contributed to the rising incidence of thyroid cancer remain speculative. However, the findings of several large, well-designed epidemiological studies have provided new information about exposures (such as obesity) that might influence the development of thyroid cancer. In this Review, we describe the changing incidence of thyroid cancer, suggest potential explanations for these trends, emphasize the implications for patients and highlight ongoing and potential strategies to combat this growing clinical and public health issue.

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

Abstract
Long-term adverse health conditions, including secondary malignant neoplasms, are common in childhood cancer survivors. Although mortality attributable to secondary malignancies declined over the past decades, the risk for developing a solid secondary malignant neoplasm did not. Endocrine-related malignancies are among the most common secondary malignant neoplasms observed in childhood cancer survivors. In this systematic review, we describe risk factors for secondary malignant neoplasms of the breast and thyroid, since these are the most common secondary endocrine-related malignancies in childhood cancer survivors. Radiotherapy is the most important risk factor for secondary breast and thyroid cancer in childhood cancer survivors. Breast cancer risk is especially increased in survivors of Hodgkin lymphoma who received moderate- to high-dosed mantle field irradiation. Recent studies also demonstrated an increased risk after lower-dose irradiation in other radiation fields for other childhood cancer subtypes. Premature ovarian insufficiency may protect against radiation-induced breast cancer. Although evidence is weak, estrogen-progestin replacement therapy does not seem to be associated with an increased breast cancer risk in premature ovarian-insufficient childhood cancer survivors. Radiotherapy involving the thyroid gland increases the risk for secondary differentiated thyroid carcinoma, as well as benign thyroid nodules. Currently available studies on secondary malignant neoplasms in childhood cancer survivors are limited by short follow-up durations and assessed before treatment regimens. In addition, studies on risk-modifying effects of environmental and lifestyle factors are lacking. Risk-modifying effects of premature ovarian insufficiency and estrogen-progestin replacement therapy on radiation-induced breast cancer require further study.

Abstract
PURPOSE Children receiving radiotherapy of the head, neck, or chest as treatment of primary malignancies are at increased risk for secondary thyroid malignancy. We hypothesized that current standards (yearly thyroid physical examination) lead to a substantial number of missed thyroid nodules. Our objectives were: (1) use thyroid ultrasound to assess thyroid nodules in childhood cancer survivors; and (2) compare prevalence of thyroid nodules in thyroid radiation-exposed patients as compared with cancer survivors without radiation exposure. METHODS We recruited 60 patients with thyroid radiation and chemotherapy exposure (median age at cancer diagnosis 10.8 y) and 59 patients with chemotherapy exposure alone (median age at diagnosis 4.3 y) from our long-term survivorship clinics. Each patient had a thyroid physical examination and thyroid ultrasound performed. RESULTS Thirty-three patients (27.7%) had nodules >0.3 cm of which 2 were palpated (6.1%). We found 22 radiated patients (36.7%) with nodules versus 11 nonradiated patients (18.6%) (P=0.03). Eleven patients were biopsied and 1 diagnosis of secondary papillary thyroid carcinoma was confirmed. CONCLUSION Our study supports further examination of incorporating thyroid ultrasounds into long-term survivorship follow-up guidelines in radiation-exposed patients for the detection of thyroid nodules and secondary malignancies.

Abstract
PURPOSE The purpose of this study was to evaluate correlations between treatment of malignancy by radiation therapy during childhood and the occurrence of thyroid gland pathologies detected by ultrasonography in follow-up examinations. METHODS AND MATERIALS Reductions of thyroid gland volume below 2 standard deviations of the weight-specific mean value, occurrence of ultrasonographically detectable thyroid gland pathologies, and hypothyroidism were retrospectively assessed in 103 children and adolescents 7 months to 20 years of age (median: 7 years of age) at baseline (1997-2013) treated with chemoradiation therapy (with the thyroid gland dose assessable) or with chemotherapy alone and followed by ultrasonography and laboratory examinations through 2014 (median follow-up time: 48 months). RESULTS A relevant reduction of thyroid gland volume was significantly correlated with thyroid gland dose in univariate (P<.001) and multivariate analyses for doses above 2 Gy. Odds ratios were 3.1 (95% confidence interval: 1.02-9.2; P=.046) for medium doses (2-25 Gy) and 14.8 (95% confidence interval: 1.4-160; P=.027) for high doses (>25 Gy). Thyroid gland dose was significantly higher in patients with thyroid gland pathologies during follow-up (P=.03). Univariate analysis revealed significant correlations between hypothyroidism and thyroid gland dose (P<.001). CONCLUSIONS Ultrasonographically detectable changes, that is, volume reductions, pathologies, and hypothyroidism, after malignancy treatment during childhood are associated with thyroid gland dose. Both ultrasonography and laboratory follow-up examinations should be performed regularly after tumor therapy during childhood, especially if the treatment included radiation therapy.

Abstract
Advances in diagnostics, treatment strategies, and supportive care have contributed to a marked improvement in outcomes for children with cancer. This has resulted in a growing number of long-term childhood cancer survivors. Currently there are over 360,000 individuals who are survivors of childhood cancer in the United States. However, treatment for patients with childhood cancer with chemotherapy, radiation, and/or hematopoietic stem cell transplantation can result in health-related complications that may not become evident until years after completion of treatment. As a result, several initiatives have been established to help standardize the surveillance for treatment-related late effects in childhood cancer survivors. This review highlights emerging concepts related to commonly reported late effects, such as subsequent malignant neoplasms, cardiovascular disease, and endocrinopathies. It also discusses relevant population-based screening strategies to mitigate the long-term health-related burden in vulnerable populations of survivors.

BACKGROUND This study aimed to investigate the sonographic appearances of the thyroid glands in nasopharyngeal carcinoma (NPC) patients whose cervical lymph nodes were treated with conventional radiotherapy (RT) or intensity-modulated radiotherapy (IMRT). The post-RT sonographic appearances of the thyroid glands in NPC patients were also correlated with the thyroid function. METHODS One hundred and three NPC patients who had completed RT of cervical lymph nodes using the anterior cervical field, 30 NPC patients who had completed RT of cervical lymph nodes using IMRT, and 61 healthy subjects were included in the study. Thyroid glands were sonographically assessed for their size, echogenicity, vascularity, and internal architecture. Thyroid function tests were also performed on each subject. RESULTS In comparison with the patients with abnormal thyroid function, the thyroid glands of the patients with normal thyroid function tended to be homogeneous and to have greater volume and echogenicity index (p < 0.05). Compared with those of the healthy subjects, the thyroid glands of patients previously treated with IMRT and those treated with the anterior cervical field showed significantly lower thyroid volume, lower incidence and number of nodules, and higher vascularity index (p < 0.05). CONCLUSIONS The patient's history of previous RT should be taken into consideration in the sonographic examination of the thyroid gland post-RT. © 2014 Wiley Periodicals, Inc.

Abstract
BACKGROUND Survivors of childhood cancer (SCC) who have received radiotherapy to the head, neck, and upper thorax are at higher risk of developing subsequent thyroid malignancies. As part of the post treatment long-term follow-up protocol, the current Children's Oncology Group guideline recommends surveillance by annual palpation; however, thyroid nodules are difficult to detect by physical examinations alone, and potentially malignancy-harboring nodules may be undetected. Since thyroid ultrasound is a sensitive and noninvasive procedure, it was incorporated in our institutional follow-up protocol. The aim of this study was to examine the outcome of ultrasound screening in this high-risk population. The following describes our experience from 2007 to 2013. METHODS A retrospective chart review was conducted on survivors enrolled in our follow-up program. SCC who have received direct or scattered radiation to the thyroid gland, and who were ≥10 years from the diagnosis of primary childhood cancer were considered to be at-risk. RESULTS Seventy-eight survivors met the inclusion criteria and were screened. Thyroid ultrasound detected thyroid nodule(s) in 46 patients (59%), 17 of which had nodule(s) between 5 and 10 mm (22%), and 15 patients had nodules ≥10 mm (19%). Fourteen patients (18%) underwent fine-needle aspiration biopsy. Six patients (8%) underwent surgery, and 5 (6%) had confirmed papillary carcinoma. At the time of the first ultrasound, thyroid nodules of various sizes were found. However, over time, these nodules demonstrated slow growth rates. CONCLUSIONS Incorporation of thyroid ultrasound into routine follow-up of high-risk SCC may aid in the detection of thyroid malignancies that are not clinically apparent. The use of ultrasound allows detailed characterization of the thyroid nodule and reliable monitoring of nodule progression. In SCC without suspicious nodule(s), it may be reasonable to perform screening ultrasounds less frequently due to the slow growth rate of thyroid nodules. However, in those with suspicious features, surgical work-up resulted in the removal of a high number of malignancies, with few unnecessary surgeries and complications.

Abstract
BACKGROUND There is no international consensus on surveillance strategies for differentiated thyroid carcinoma (DTC) after radiotherapy for childhood cancer. Ultrasonography could allow for early detection of DTC, however, its value is yet unclear since the prognosis of DTC is excellent. We addressed the evidence for the question: 'is outcome of DTC influenced by tumor stage at diagnosis?'. METHODS A multidisciplinary working group answered the sub-questions: 'is recurrence or mortality influenced by DTC stage at diagnosis? Does detection of DTC at an early stage contribute to a decline in adverse events of treatment?' The literature was systematically reviewed, and conclusions were drawn based on the level of evidence (A: high, B: moderate to low, C: very low). RESULTS In children, level C evidence was found that detection of DTC at an early stage is associated with lower recurrence and mortality rates. No evidence was found that it influences morbidity rates. In adults, clear evidence was found that less advanced staged DTC is a favorable prognostic factor for recurrence (level B) and mortality (level A). Additionally, it was found that more extensive surgery increases the risk to develop transient hypoparathyroidism (level A) and that higher doses of radioiodine increases the risk to develop second primary malignancies (level B). CONCLUSION Identification of DTC at an early stage is beneficial for children (very low level evidence) and adults (moderate to high level evidence), even considering that the overall outcome is excellent. These results are an important cornerstone for the development of guidelines for childhood cancer survivors at risk for DTC.

Abstract
OBJECTIVE To investigate the late side effects of childhood cancer therapy on the thyroid gland and to determine the risk factors for development of thyroid disorder among childhood cancer survivors. METHODS One hundred and twenty relapse-free survivors of childhood cancer (aged 6-30 years) were included in this study. The diagnoses of patients were lymphoma, leukemia, brain tumor, rhabdomyosarcoma and nasopharyngeal carcinoma (NPC). The patients were divided into two groups depending on the treatment: group 1-chemotherapy (ChT) only (n=52) and group 2-combination therapy of ChT + radiotherapy (RT) (head/neck/thorax) (n=68). Thyroid function tests, urinary iodine levels, and thyroid gland ultrasound examinations were evaluated in both groups. RESULTS Incidence of thyroid disease was 66% (n=79) in the survivors. The thyroid abnormalities were: hypothyroidism (HT) (n=32, 27%), thyroid nodules (n=27, 22%), thyroid parenchymal heterogeneity (n=40, 33%), autoimmune thyroiditis (n=36, 30%), and thyroid malignancy (n=3, 2%). While the incidence of HT and thyroid nodules in group 2 was significantly higher than in group 1, the incidence of thyroid parenchymal heterogeneity and autoimmune thyroiditis was similar in the two patient groups. HT and thyroid malignancy were seen only in group 2. In multivariate logistic regression analysis, a history of Hodgkin lymphoma (HL), brain tumor and NPC, as well as cervical irradiation and 5000-5999 cGy doses of radiation were found to constitute risk factors for HT. History of HL and 4000-5999 cGy doses of radiation were risk factors for thyroid nodules. Head/neck irradiation and treatment with platinum derivatives were risk factors for autoimmune thyroiditis. In univariate analysis, a history of NPC, cervical + nasopharyngeal irradiation, and treatment with platinum derivatives were risk factors for thyroid parenchymal heterogeneity. CONCLUSION Our results indicate that there is especially an increased risk of HT and thyroid nodules in patients treated with combination therapy of ChT with head/neck/thorax RT. Although chemotherapeutic agents per se do not seem to cause HT, longer follow-up is needed to assess whether or not there is an increased risk for autoimmune thyroiditis and thyroid parenchymal heterogeneity after antineoplastic therapy.

Abstract
BACKGROUND Thyroid nodules in pediatric patients may carry a greater risk for malignancy than in adults. Most nodules >1 cm in patients ≤ 21 years of age may require thyroidectomy for definitive diagnosis and treatment. Although clinic-based ultrasound (CBUS) has been shown useful in the evaluation of thyroid nodules in adults, its utility in evaluating nodules in the pediatric population remains unclear. METHODS Prospectively collected data regarding 50 patients ≤ 21 years who underwent preoperative CBUS and initial thyroidectomy at a single institution were retrospectively reviewed. All CBUS were performed by endocrine surgeons certified in basic and cervical ultrasonography. Preoperative CBUS characteristics of pediatric thyroid nodules were analyzed with respect to final pathology. RESULTS Of the 50 patients ≤ 21 years of age who underwent surgical resection for a dominant thyroid nodule, there were 45 females and 5 males with an average age of 17.4 years (range: 10-21 years). On univariate analysis, microcalcifications (p<0.001), abnormal lymph nodes (p<0.001), and dimensions taller more than wide (p=0.033) were individual CBUS characteristics predictive of thyroid malignancy. All nine patients with abnormal lymph nodes on CBUS had malignant disease on final pathology. Multiple thyroid nodules, a cystic component, and echogenicity did not predict malignancy; regular borders trended toward predicting a benign nodule (p=0.066). When malignant ultrasound features were considered (i.e., hypoechoic, irregular borders, microcalcifications, abnormal lymph nodes, and shape taller more than wide), having one malignant feature predicted malignancy with an odds ratio of 2.0 while having ≥ 2 features held even greater significance (p=0.004, OR 4.0). All patients with ≥ 3 malignant ultrasound features had thyroid cancer on final pathology. CONCLUSION CBUS is a useful diagnostic modality in determining malignancy status of thyroid nodules in patients ≤ 21 years of age. CBUS should be employed as part of an initial assessment of any pediatric patient presenting with thyroid nodules to help further guide management and treatment.

Abstract
The effects of ionizing radiation on the thyroid have been studied for several decades, and nuclear accidents are the major source of information about the subject. There is an association of hypothyroidism, hyperthyroidism, thyroid nodules and cancer with radiation, but the threshold dose, mechanism of injury, and some risk factors have not been fully established. Children are more susceptible to thyroid injury caused by radiation and require prolonged follow-up after exposure. This issue is especially relevant nowadays, since a large number of people treated with radiation for childhood cancer survive and may have sequelae. Diagnostic radiology tests also represent a source of exposure to radiation in the pediatric population. In this review, we analyze different clinical and pathological changes, and the mechanisms of thyroid lesions caused by radiotherapy and computed tomography in children and adolescents. It is important to understand these data for prevention, early detection, and treatment of thyroid dysfunction.

Abstract
PURPOSE Medulloblastoma (MB) is one of the most frequent and sensitive to radiation aggressive brain tumor in children. Abnormalities of the thyroid function are common complications of head and neck irradiation for childhood cancer. The aim of this study was to assess thyroid function in children treated for medulloblastoma according to the treatment protocol phase. PATIENTS AND METHODS Twenty-three children with MB were enrolled to this study. All patients underwent chemotherapy and radiotherapy to the whole craniospinal axis and boost with the conformal therapy restricted to the tumor bed to a total dose of 54 Gy. Thyroid function was evaluated based on thyroid-stimulating hormone (TSH), free thyroxine (fT4) levels controlled before MB treatment, directly after irradiation and at the end of the treatment protocol. Ultrasonography has been used to detect parenchymal abnormalities. RESULTS All patients presented normal thyroid hormone range before chemotherapy. Hypothyroidism was found in 12 patients in the course of treatment, in 2 patients hormone deficits diagnosed directly after irradiation, in 10 patients such condition was observed at the end of the whole therapy. All of these patients needed thyroid hormone substitution. None of them presented clinical symptoms of hypothyroidism. Ultrasound-detected abnormalities have been found in 20 patients. CONCLUSIONS It is crucial to monitor the functions of the thyroid gland in children treated for medulloblastoma because of the high risk of hypothyroidism resulting from the treatment. The change in the echogenicity of the thyroid gland may be an early marker for a dysfunction of this organ in children treated for medulloblastoma.

Abstract
BACKGROUND Incidental thyroid abnormalities detected on US examinations in children have not been well documented. OBJECTIVE To determine prevalence of incidental thyroid abnormalities depicted by US in children and to describe the spectrum of appearances. MATERIALS AND METHODS Retrospective analysis of clinical and US findings in children who had neck US from January 2006 to December 2007. RESULTS Of 1,228 neck US exams, thyroid was depicted in 287 children (mean age = 6.2 years). Incidental thyroid abnormalities were detected in 52 (18%) (mean age = 8.1 years). In 35 there were small (<4 mm), well-defined cysts, some with a hyperechoic punctate focus. In nine there were hypoechoic, solid nodules with smooth, straighter margins with echogenicity similar to thymus, suggesting intrathyroid ectopic thymus (mean age = 2.5 years). In three others there were tiny hyperechoic foci without nodules. Other abnormalities included hypoechoic target-like lesions (n = 2), isoechoic nodule (n = 1), multiple hypoechoic foci (n = 1) and non-visualized thyroid lobe resulting from adjacent abscess (n = 1). None of the children developed thyroid dysfunction or malignancy. CONCLUSION There is a spectrum of incidental thyroid abnormalities in children. These US findings should be interpreted cautiously, avoiding unnecessary referrals and investigations. Intrathyroid ectopic thymus is more common than previously thought, occurs much more frequently in younger boys and should be considered if the lesion has US characteristics of thymus.

Abstract
Radiation exposure of the thyroid at a young age is a recognized risk factor for the development of differentiated thyroid cancer lasting for four decades and probably for a lifetime after exposure. Medical radiation exposure, however, occurs frequently, including among the pediatric population, which is especially sensitive to the effects of radiation. In the past, the treatment of benign medical conditions with external radiation represented the most significant thyroid radiation exposures. Today, diagnostic medical radiation represents the largest source of man-made radiation exposure. Radiation exposure related to the use of computerized tomography is rising exponentially, particularly in the pediatric population. There is direct epidemiological evidence of a small but significant increased risk of cancer at radiation doses equivalent to computerized tomography doses used today. Paralleling the increasing use of medical radiation is an increase in the incidence of papillary thyroid cancer. At present, it is unclear how much of this increase is related to increased detection of subclinical disease from the increased utilization of ultrasonography and fine-needle aspiration, how much is due to a true increase in thyroid cancer, and how much, if any, can be ascribed to medical radiation exposure. Fortunately, the amount of radiation exposure from medical sources can be reduced. In this article we review the sources of thyroid radiation exposure, radiation risks to the thyroid gland, strategies for reducing radiation exposure to the thyroid, and ways that endocrinologists can participate in this effort. Finally, we provide some suggestions for future research directions.

Abstract
In the last four decades, advances in therapies for primary cancers have improved overall survival for childhood cancer. Currently, almost 80% of children will survive beyond 5 years from diagnosis of their primary malignancy. These improved outcomes have resulted in a growing population of childhood cancer survivors. Radiation therapy, while an essential component of primary treatment for many childhood malignancies, has been associated with risk of long-term adverse outcomes. The Childhood Cancer Survivor Study (CCSS), a retrospective cohort of over 14,000 survivors of childhood cancer diagnosed between 1970 and 1986, has been an important resource to quantify associations between radiation therapy and risk of long-term adverse health and quality of life outcomes. Radiation therapy has been associated with increased risk for late mortality, development of second neoplasms, obesity, and pulmonary, cardiac and thyroid dysfunction as well as an increased overall risk for chronic health conditions. Importantly, the CCSS has provided more precise estimates for a number of dose-response relationships, including those for radiation therapy and development of subsequent malignant neoplasms of the central nervous system, thyroid and breast. Ongoing study of childhood cancer survivors is needed to establish long-term risks and to evaluate the impact of newer techniques such as conformal radiation therapy or proton-beam therapy.

Abstract
We report two cases of papillary thyroid carcinoma occurring after the successful treatment of osteosarcoma. One of the patients was administered with several alkylating agents and topoisomerase II inhibitor as part of the primary treatment of osteosarcoma. The onset of thyroid carcinoma occurred after 5 and 12 yr after cessation of the osteosarcoma therapy. All the patients involved in this study are alive and free of their malignancies. There have been eight case reports of these two malignancies occurring in the same patient. Thyroid carcinoma rarely occurs in patients with osteosarcoma; however, vigilant surveillance and long-term follow-up should be emphasized for all survivors.

Abstract
Hematopoietic cell transplantation (HCT) following high-dose chemotherapy or chemoradiotherapy for children with malignant or nonmalignant hematologic disorders has resulted in an increasing number of long-term disease-free survivors. The preparative regimens include high doses of alkylating agents, such as CY with or without BU, and may include TBI. These agents impact the neuroendocrine system in growing children and their subsequent growth and development. Children receiving high-dose CY or BUCY have normal thyroid function, but those who receive TBI-containing regimens may develop thyroid function abnormalities. Growth is not impacted by chemotherapy-only preparative regimens, but TBI is likely to result in growth hormone deficiency and decreased growth rates that need to be treated with synthetic growth hormone therapy. Children who receive high-dose CY-only have normal development through puberty, whereas those who receive BUCY have a high incidence of delayed pubertal development. Following fractionated TBI preparative regimens, approximately half of the patients have normal pubertal development. These data demonstrate that the growth and development problems after HCT are dependent upon the preparative regimen received. All children should be followed for years after HCT for detection of growth and development abnormalities that are treatable with appropriate hormone therapy.

Abstract
Thyroid disease does occur in the pediatric patient, and imaging plays an important role in its evaluation. A review is presented of normal development of the thyroid gland, the technique and indications for thyroid sonography, and key imaging features of congenital thyroid disorders (ectopic or absent thyroid, infantile goiter, thyroglossal duct remnants), benign thyroid masses (follicular adenoma, degenerative nodules, colloid and thyroid cysts), malignant masses (follicular, papillary and medullary carcinoma) and diffuse thyroid disease (acute bacterial thyroiditis, Hashimoto's thyroiditis, Grave's disease).

Abstract
BACKGROUND Survivors of Hodgkin lymphoma and other patients who receive neck irradiation are at increased risk of thyroid cancer. Ultrasonography provides an inexpensive and non-invasive method of thyroid screening, but the clinical significance of thyroid nodules detected by ultrasound screening is uncertain. PROCEDURE We reviewed the demographics, clinical characteristics, method of detection, and outcome of patients who developed thyroid nodules after treatment for pediatric Hodgkin lymphoma at our institution. One radiologist reviewed all imaging studies. RESULTS Sixty-seven children treated for Hodgkin lymphoma from 1962 to 2001 developed thyroid nodules. The study group represented 9,024 person-years of follow-up after the diagnosis of Hodgkin lymphoma and 581 person-years after diagnosis of a thyroid nodule. A median of 10.5 years (range, 0.2-24.8 years) elapsed between the diagnoses of Hodgkin lymphoma and thyroid nodule(s). All but one patient had received neck irradiation for Hodgkin lymphoma, with a median thyroid radiation dose of 35 Gy (range, 12-45 Gy). Thyroid nodules were found to be malignant in seven patients (10%), at a median of 16.2 years (range, 8.4-23.7 years) after diagnosis of Hodgkin lymphoma. Only one malignancy was found through screening ultrasonography. All patients with thyroid cancer remained disease-free at 0.4-16.2 years of follow-up. CONCLUSIONS Thyroid nodules are common in Hodgkin lymphoma survivors treated with neck irradiation, but the majority of these lesions have an indolent clinical course and do not undergo malignant transformation. Only patients with a palpable mass or clinical symptoms need more extensive evaluation, including Doppler-flow ultrasonography and fine-needle aspiration.

Abstract
This article reviews the clinical utility of modern imaging techniques, particularly ultrasound (US), CT, and MRI in children with disorders of the thyroid and adrenal glands. Radionuclide scanning is the modality of choice in making the anatomic diagnosis in neonates with congenital hypothyroidism, while US is most useful in defining nodular thyroid disease. CT and MRI of the thyroid tend to be limited to defining the extent of thyroid carcinoma. Adrenal US is an essential step in the differential diagnosis of ambiguous genitalia or salt-losing crises in the newborn, while CT and MRI are more useful in defining the anatomy of the adrenals in older children with tumors or diffuse hyperplasia of the glands.

Abstract
BACKGROUND/PURPOSE Thyroid carcinomas can occur as a primary malignancy (PTM) or secondary after another malignancy (STM). Information about the presentations and outcomes of patients with STM are limited. The authors sought to compare the clinical characteristics, course, and outcomes of patients with primary or secondary thyroid malignancies. METHODS The authors reviewed the medical records of 8 children with PTM and 17 children with STM referred to St Jude Children's Research Hospital between February 1962 and February 2002 for evaluation and treatment of malignant thyroid carcinoma. RESULTS The 8 children who had primary thyroid carcinoma had it diagnosed at a median age of 12.5 years (range, 7.3 to 16.3 years). Seven patients had papillary carcinoma, and 1 patient had follicular carcinoma. Three of the 8 (37.5%) had metastatic disease involving regional lymph nodes; 2 patients (25.0%) had lung metastases. Six patients required radioactive iodine (I 131) ablation for residual or metastatic disease after surgical resection. All 8 patients remain alive a median of 22.6 years after diagnosis (range, 0.7 to 30.5 years); 1 continues to receive radioactive iodine (I 131) ablation for persistent disease. Seventeen patients had thyroid carcinoma as a second malignant neoplasm after treatment for acute lymphoblastic leukemia (n = 6), Hodgkin's disease (n = 5), central nervous system tumor (n = 2), Wilms' tumor (n = 1), retinoblastoma (n = 1), non-Hodgkin's lymphoma (n = 1), or neuroblastoma (n = 1). Patients with secondary thyroid carcinoma presented at a median age of 21.5 years (range, 15.3 to 42.6 years), a median of 16.2 years (range, 0.9 to 29.2 years) after diagnosis of the primary cancer. Twelve of the 17 patients (70.6%) had received radiation to the thyroid gland during therapy for the primary cancer. Four patients (23.5%) had metastatic disease involving regional lymph nodes. Six patients (35.3%) required I(131) ablation for residual or metastatic disease after thyroidectomy. At the time of this report, all 17 patients are alive and in continue to be free of disease. CONCLUSIONS Pediatric thyroid carcinoma is uncommon and responds well to current therapy. Given the limited period of follow-up of our cohort of secondary malignant thyroid tumors that arise after childhood cancer, these lesions appear to have similar presentations and outcomes when compared with primary carcinomas and can therefore be managed in the same manner.

Abstract
Therapeutic advances in the treatment of pediatric neoplasms have improved the prognosis but have also increased the risk of developing rare second malignant neoplasms (SMNs). Primary neoplasms that are often associated with SMNs include lymphoma, retinoblastoma, medulloblastoma, neuroblastoma, and leukemia. The most common SMNs are central nervous system (CNS) tumors, sarcomas, thyroid and parotid gland carcinomas, and leukemia, particularly acute myeloblastic leukemia. Genetic predisposition, chemotherapy, and especially radiation therapy are implicated as pathogenic factors in SMN. All survivors of childhood cancer should have lifelong follow-up, preferably with magnetic resonance imaging, which does not require ionizing radiation and provides greater anatomic detail and resolution in the head and neck region and the CNS. A new or progressive lesion may represent recurrence of the primitive neoplastic process, late radiation injury, or, more infrequently, an SMN. Differential diagnosis can be very difficult, and outcome is often fatal. Treatment protocols should be modified to reduce the risk for SMN without compromising the effectiveness of initial therapy. Clinicians should individualize treatment for patients who are genetically predisposed to SMN. In addition, radiologists should be familiar with the long-term consequences of antineoplastic therapy to facilitate diagnosis and anticipate adverse outcomes.

Abstract
BACKGROUND Recent data indicate that the risk of developing a thyroid neoplasm clearly is increased after high-dose, therapeutic radiation therapy during childhood. To better understand the time course, natural history, and histopathology of thyroid lesions that develop after high-dose irradiation, the authors undertook a retrospective study of all survivors of childhood and adolescent malignancies who were treated at Memorial Sloan-Kettering Cancer Center and who developed a clinically apparent thyroid neoplasm. METHODS The authors searched the data base of the Department of Pediatrics, the hospital-based tumor registry, and the hospital medical records database for patients with thyroid neoplasms. RESULTS Thirty-three patients were identified who developed a thyroid neoplasm after therapeutic radiation. Primary diagnoses were Hodgkin disease (n = 18 patients), non-Hodgkin lymphoma (n = 10 patients), acute lymphoblastic leukemia (n = 2 patients), acute myeloid leukemia (n = 1 patient), Wilms tumor (n = 1 patient), and neuroblastoma (n = 1 patient). The median age at the time of diagnosis of the primary malignancy was 12.0 years (range, 3.7-18.3 years), the median radiation dose to the thyroid gland was 2400 centigrays (cGy; range, 1000-4200 cGy), and the median interval from the time of radiation therapy until the recognition of thyroid disease was 13.0 years (range, 6.2-30.1 years). Thirteen of 33 thyroid lesions (39%) were malignant (11 papillary carcinomas and 2 follicular carcinomas). Age at diagnosis, gender ratio, and time elapsed since initial treatment did not differ between patients with malignant and benign lesions, but the median radiation dose to the thyroid was lower in patients who had malignant disease compared with patients who had benign disease (2000 cGy vs. 2950 cGy; P = 0.03). Disease was confined to the neck in all patients who had malignant thyroid lesions; after a median follow-up of 6.5 years (range, 0.9-12 years), none of the patients developed progressive or recurrent disease. CONCLUSIONS Data from this study suggest that a high proportion of clinically apparent thyroid neoplasms that develop after therapeutic radiation for a childhood malignancy are malignant. However, most of these thyroid malignancies do not appear to behave in an aggressive fashion. Because thyroid neoplasms may not become evident for decades after radiation therapy, all individuals who are at risk require life-long follow-up.

Abstract
OBJECTIVES To describe a cohort of survivors of childhood malignancy at risk of developing thyroid abnormality, and propose guidelines for management of such patients. DESIGN Retrospective case series. SETTING Late-effects oncology clinic at a large children's hospital in Sydney. SUBJECTS 142 patients who had received irradiation to the thyroid from the 1970s onwards, who attended the late-effects clinic from May 1989 to December 1998. INTERVENTIONS Thyroid palpation by an endocrinologist or surgeon, serum thyroid-stimulating hormone assay and thyroid ultrasound examination were performed on all subjects and, depending on findings, some subjects proceeded to fine-needle biopsy or surgery (total thyroidectomy). A few patients required adjuvant (131)I administration. OUTCOME MEASURES Radiation dose received; results of thyroid palpation; thyroid function tests; ultrasound findings; diagnosis of the abnormalities; and outcomes of surgical interventions. RESULTS 49 subjects (24 of 65 patients who received scatter irradiation to the thyroid and 25 of 78 patients who received direct irradiation) had thyroid surgery. Of these, 12 in the scatter and six in the direct irradiation group were found to have thyroid malignancy. Fifty subjects with abnormal ultrasound results remain under surveillance. Having a palpable thyroid was predictive of malignancy, but age at original diagnosis, sex, current age, time since irradiation, radiation dose, nodule type and nodal involvement were not. CONCLUSION There is a significant risk of cancer in thyroid glands exposed to radiation as part of therapy for childhood cancer. This risk is greater for patients who received scatter (versus direct) irradiation. Nodular change is usually not apparent for many years, so lifelong surveillance is necessary. Palpation alone is not sufficient to detect thyroid cancer and thyroid ultrasound examination is recommended.

Abstract
With an ever increasing adult population of childhood cancer survivors there is a need to focus on the late effects of cancer therapy. It is essential that, after discharge from the paediatric oncologists, the patients are not lost from the health system but are under continued surveillance with access to the appropriate physicians. Endocrine and metabolic consequences may affect a patient's life both soon after cancer treatment and also for many years in the future. In this review we consider the following potential problems: growth hormone deficiency and replacement in adulthood, cardiovascular risk factors, osteopaenia, thyroid and parathyroid dysfunction.

Abstract
The aim of this article is to provide an up to date review of second malignant neoplasms (SMN's) following treatment for childhood cancer, referring to their incidence, the role of genetic factors, and how the primary malignancy and treatment received influence the type, site and prognosis of SMN's. The role of genetic factors will be discussed as far as they impact upon a predisposition to later development of SMN's. The primary malignancies that have important associations with SMN's will then be discussed, in particular Hodgkin's disease, retinoblastoma and acute lymphoblastic leukaemia. The important second malignancies will be highlighted, including tumours of the CNS and thyroid, osteosarcoma, secondary acute myeloid leukaemia and melanoma. Emphasis will be put upon identifying which patients are most likely to suffer from these tumours. An important part of the article are case histories. These are provided in combination with illustrations as a useful adjunct to the text, with a particular emphasis on radiological features, diagnosis and screening. Finally, the important but different roles of causal agents, in particular chemotherapy and radiotherapy are highlighted.

Abstract
BACKGROUND Children treated with radiotherapy to the neck or exposed to environmental radiation are at risk for developing thyroid cancer later in life. The best method for screening these high-risk patients is unclear. We systematically reviewed evidence on the accuracy of ultrasound and palpation to detect thyroid nodules and of fine needle aspiration (FNA), a confirmatory test, to diagnose thyroid cancer. PROCEDURE We searched the MEDLINE database for papers published since 1966, using the MeSH term thyroid neoplasms and terms related to diagnostic test performance. To supplement our MEDLINE searches, we searched reference lists from recent reviews and articles recommended by thyroid cancer experts. We recorded the tests used, the gold standard determination of disease, the test performance results, and the presence of biases that could affect the reported results. We also abstracted the number of patients who underwent surgery and the final diagnoses. We created two decision models: one for screening 10,000 medically irradiated patients, and one for screening 10,000 environmentally irradiated patients. RESULTS Using ultrasound as the gold standard determination of the presence of a nodule, the sensitivity of palpation for all sized nodules was 10-41 percent, indicating that a high proportion of nodules detected by ultrasound are too small to be palpated. Sensitivity of palpation increased with nodule size. The specificity of palpation ranged from 95 to 100%. In studies from referral centers, the reported sensitivity and specificity of FNA were 71-95 and 52-99%, respectively. However, most authors excluded the proportion of patients (6-33%) who had inadequate or nondiagnostic FNA results when calculating sensitivity and specificity, even though 6-100% of these patients went on to have a diagnostic lobectomy. When each study was reanalyzed so that patients with nondiagnostic FNA results who went directly to surgery were reclassified as positive tests, sensitivity increased slightly, but specificity dropped by 4-20 percentage points per study. The decision model for screening 10,000 medically irradiated patients revealed that if ultrasound were used as an initial screen, 2,741 patients would have nodules at least 1 cm in size; assuming no patients with smaller nodules had surgery, 1,964 patients would have surgery; 275 patients would have a diagnosis of thyroid cancer. Screening with ultrasound as an initial test would detect an additional 150 cases of thyroid cancer compared to those screened with palpation. However, an additional 1,689 patients would have surgery for nonmalignant nodules (compared to 480 patients with nonmalignant nodules screened with palpation). The yield for screening 10,000 environmentally irradiated patients was several times smaller than for screening 10,000 medically irradiated patients. If 10,000 environmentally irradiated patients were screened initially with ultrasound, approximately 708 patients would have nodules at least 1 cm in size; 89 patients would have surgery; and 38 patients would be diagnosed with thyroid cancer. CONCLUSIONS Regardless of type of exposure, testing initially with ultrasound detects several times more cases of thyroid cancer than palpation. However, when ultrasound is the initial test, many more patients also have surgery for nonmalignant nodules. Screening with palpation is not very reassuring, particularly to medically irradiated patients with negative tests, since almost half (46%) of these patients may have undetected nodules.

Abstract
Follicle-derived thyroid cancer is rare in the young. The authors examined a population with a low rate of radiation exposure and who were treated at a single institution. The records of 56 patients diagnosed before the age of 25 years were analyzed. The majority of patients presented with an asymptomatic thyroid mass. All patients were treated surgically and half received postoperative ablation with 131I. Recurrent disease was detected in 29%. The presence of local metastases at initial surgery was a predictor of recurrence. No patient presented with distant metastases and no patient died of thyroid cancer. Although radiation exposure remains a risk factor for thyroid cancer in the young, only a minority of patients with thyroid cancer have a known history of exposure. Patients who are diagnosed at a young age have a high rate of long-term recurrence, and should be followed closely throughout their lives.

Abstract
BACKGROUND We studied the value of thyroid ultrasonography as a follow-up tool in survivors of childhood lymphomas and correlated morphologic abnormalities with thyroid function tests. PROCEDURE A prospective follow-up study of 45 long-term survivors of histology-proved childhood lymphomas was performed. Mean age at diagnosis was 9.1 years (range 2.1-16.4 years) and mean follow-up duration 10.9 years (range 3.9-22.2 years). RESULTS Among the 26 survivors of Hodgkin disease (HD) who received mantle field irradiation, 14 (54%) had abnormal ultrasonograms. Elevated thyroid-stimulating hormone (TSH) concentrations were found in 14 (54%), and 6 of them (42%) had normal thyroid functions. Six of twelve patients with normal ultrasonograms had abnormal thyroid function, and 5 of 11 patients with normal function had abnormal sonograms. Among the 19 non-HD survivors who did not receive radiotherapy, 18 (95%) had both normal sonograms and normal function. Thus thyroid gland abnormalities were detected in 54% of HD survivors after mantle field irradiation. No correlation between the abnormalities detected on ultrasonography and serum levels of TSH and thyroid hormones were found. CONCLUSIONS Both ultrasound and thyroid function tests independently provide clinically useful information; the former examines gland morphologogy and the latter evaluates hormonal changes associated with thyroid disease. The high frequency of thyroid abnormalities detected by ultrasonography suggests that periodic thyroid ultrasonography is advisable in the follow-up of patients treated with mantle irradiation to screen for morphologic changes that may presage malignant transformation.

Abstract
Patients who receive radiotherapy to the neck are at risk of developing thyroid dysfunction. This prospective study of patients whose treatment for Hodgkin's disease in childhood included radiotherapy to the neck aimed to investigate the incidence and natural history of thyroid dysfunction and the morphological changes of the gland demonstrated on ultrasound. Forty-seven patients were investigated by clinical examination, thyroid function tests and thyroid ultrasound. Only six patients had a clinically detectable abnormality, but 64% had abnormal thyroid function tests. All patients had an abnormal thyroid ultrasound scan and 42% had at least one focal abnormality. A significant association was found between the presence of a focal lesion on ultrasound and young age at radiotherapy, longer follow-up and the length of time that the thyroid-stimulating hormone (TSH) level had been elevated. During follow-up, 65% of patients not on thyroxine developed new focal abnormalities. The longest time interval between radiotherapy and an increase in TSH level was 94 months, and from radiotherapy to the appearance of a focal abnormality on thyroid ultrasound was over 18 years. Three patients were found to have a thyroid carcinoma. These findings indicate the importance of long-term follow-up for patients treated by neck irradiation for Hodgkin's disease in childhood.

Abstract
The impact of recently intensified and novel therapies for the treatment of childhood cancer has been an increased number of survivors and an increase in the number of treatment complications among survivors. Thus, it is important for the primary care practitioner to be aware of not only acute but chronic complications of therapy, including the possibility of second malignancies. Long-term follow-up is essential, and continuous education of patients and health care personnel is an important aspect for the complete success of treatment. Primary care practitioners also need to incorporate other subspecialties in the management of these patients to ensure that they receive complete evaluation and treatment.
