Imaging and Imaging-Based Management of Pediatric Thyroid Nodules.

ABSTRACT: Thyroid nodules are less frequent in children than adults. Childhood thyroid nodules carry specific features, including a higher risk of malignancy than nodules in adults, rendering them unique in terms of management. Subsequently, they should be considered a distinct clinical entity with specific imaging recommendations. Initial evaluation requires a thorough workup, including clinical examination, and a detailed personal and familial history to determine the presence of possible risk factors. Laboratory and radiologic evaluation play an integral part in the diagnostic algorithm, with ultrasonography (US) being the first diagnostic test in all patients. US elastography has been recently introduced as an incremental method, reducing the subjectivity of the clinical diagnosis of nodule firmness associated with increased malignancy risk. However, fine-needle aspiration biopsy (FNAB) remains the mainstay in the diagnostic work-up of thyroid nodules and is documented to be best method for differentiating benign from malignant thyroid nodules. In addition, thyroid scintigraphy provides functional imaging information, which has a role both in the diagnostic management of thyroid nodules and during follow up in malignancies. Finally, despite providing additional information in certain clinical scenarios, 18F-fludeoxyglucose Positron Emission Tomography (18F-FDG-PET), computed tomography (CT), and magnetic resonance imaging (MRI) imaging are not routinely recommended for the evaluation of patients with newly detected thyroid nodules or in all cases of thyroid cancer. The objective of this review is to summarize the concepts in imaging and imaging-based management of nodular thyroid disease in the pediatric population, acknowledging the unique features that this patient group carries and the specific approach it requires.

Project description:ImportanceThyroid cancer is the most common pediatric endocrine malignant neoplasm. Disparities in the workup of thyroid nodules may be significantly associated with thyroid cancer outcomes.ObjectiveTo determine the association of sociodemographic factors with the odds of receiving a biopsy, timeliness of the procedure, and risk of nodule malignancy.Design, setting, and participantsThis was a retrospective cross-sectional study using insurance claims data from the Optum Clinformatics Data Mart database. The study cohort comprised pediatric patients diagnosed with single thyroid nodules between 2003 and 2020. Data analysis was performed from January 1, 2003, to June 30, 2020.Main outcomes and measuresMultivariable logistic regression models were used to identify demographic variables associated with biopsy and nodule malignant neoplasm. A multivariable linear regression model was used to assess the time between thyroid nodule diagnosis and biopsy.ResultsOf 11 643 children (median [IQR] age at diagnosis or procedure, 15 [12-17] years; 8549 [73.2%] were female and 3126 [26.8%] were male) diagnosed with single thyroid nodules, 2117 (18.2%) received a biopsy. Among the patients who received a biopsy, 304 (14.4%) were found to have a malignant nodule. Greater parental education was associated with a shorter diagnosis-to-biopsy interval (mean difference, -7.24 days; 95% CI, -13.75 to -0.73). Older age at nodule diagnosis (odds ratio [OR], 1.11; 95% CI, 1.09-1.13) and female gender (OR, 1.25; 95% CI, 1.11-1.40) were associated with increased odds of receiving a biopsy, while Black/African American (OR, 0.80; 95% CI, 0.65-0.99) and Hispanic (OR, 0.84; 95% CI, 0.72-0.99) patients had lower odds of receiving a biopsy compared with White patients. Finally, female gender (OR, 1.08; 95% CI, 0.80-1.47) was not associated with lower odds of nodule malignant neoplasm.Conclusions and relevanceFindings of this cross-sectional study highlight disparities in the diagnostic management of pediatric thyroid nodules. These results call for future work to ensure equitable access to thyroid care for all children.

Project description:BackgroundThyroid nodules are a common clinical problem, and differentiated thyroid cancer is becoming increasingly prevalent. Since the American Thyroid Association's (ATA's) guidelines for the management of these disorders were revised in 2009, significant scientific advances have occurred in the field. The aim of these guidelines is to inform clinicians, patients, researchers, and health policy makers on published evidence relating to the diagnosis and management of thyroid nodules and differentiated thyroid cancer.MethodsThe specific clinical questions addressed in these guidelines were based on prior versions of the guidelines, stakeholder input, and input of task force members. Task force panel members were educated on knowledge synthesis methods, including electronic database searching, review and selection of relevant citations, and critical appraisal of selected studies. Published English language articles on adults were eligible for inclusion. The American College of Physicians Guideline Grading System was used for critical appraisal of evidence and grading strength of recommendations for therapeutic interventions. We developed a similarly formatted system to appraise the quality of such studies and resultant recommendations. The guideline panel had complete editorial independence from the ATA. Competing interests of guideline task force members were regularly updated, managed, and communicated to the ATA and task force members.ResultsThe revised guidelines for the management of thyroid nodules include recommendations regarding initial evaluation, clinical and ultrasound criteria for fine-needle aspiration biopsy, interpretation of fine-needle aspiration biopsy results, use of molecular markers, and management of benign thyroid nodules. Recommendations regarding the initial management of thyroid cancer include those relating to screening for thyroid cancer, staging and risk assessment, surgical management, radioiodine remnant ablation and therapy, and thyrotropin suppression therapy using levothyroxine. Recommendations related to long-term management of differentiated thyroid cancer include those related to surveillance for recurrent disease using imaging and serum thyroglobulin, thyroid hormone therapy, management of recurrent and metastatic disease, consideration for clinical trials and targeted therapy, as well as directions for future research.ConclusionsWe have developed evidence-based recommendations to inform clinical decision-making in the management of thyroid nodules and differentiated thyroid cancer. They represent, in our opinion, contemporary optimal care for patients with these disorders.
