Recurrence and survival for patients with thyroid carcinoma in the pediatric age group in the Emirate of Abu Dhabi: retrospective analysis of a multicentre cohort. J Pediatr Endocrinol Metab 2024; 37:52-61. [PMID: 38015567 DOI: 10.1515/jpem-2023-0268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 10/20/2023] [Indexed: 11/29/2023]
Abstract
OBJECTIVES Pediatric thyroid cancer represents 2.3 % of thyroid cancers, and its long-term outcome data are sparse. There have not been studies in the UAE delineating its epidemiology, clinical and histological characteristics, and follow-up outcomes. We aimed to evaluate the clinical-pathological behavior, recurrence and survival rates in pediatrics with all types of thyroid cancer in the UAE. METHODS Multicentre retrospective chart review analysis of pediatric patients with thyroid carcinoma from January 2010 to December 2020 in Abu Dhabi, UAE. RESULTS Thirty-four patients were included, 85 % being females. Papillary thyroid carcinoma (PTC) was the commonest type of thyroid cancer (88 %) vs. follicular thyroid carcinoma (FTC) (11.8 %). Almost half of our patients had a multifocal disease, 26 % had lymphovascular invasion (LVI), and 21 % had extrathyroidal extension (ETE). There were no mortalities during follow-up. 85 % of patients exhibited complete remission, while 15 % of patients showed evidence of progressive residual or recurrent disease. One patient had metastasis to lymph nodes and lungs. CONCLUSIONS There were similar trends of incidence, sex prevalence, and histopathological patterns as the ones observed internationally. Potential risk factors in our population include a family history of thyroid cancer and obesity. The lower rate of ETE, LVI, metastasis, and recurrence indicates a possibly less aggressive disease.

Abstract
BACKGROUND Outcomes of paediatric thyroid surgery have only been reported in smaller series or over long intervals. The aim of this multicentre study was to describe the recent outcomes of paediatric thyroid surgery in Germany and Austria. METHODS Patients aged less than or equal to 18 years who underwent thyroid surgery and were prospectively documented in the StuDoQ|Thyroid registry between March 2017 and August 2022 were studied. RESULTS In total, 604 patients from 90 institutions were included. The mean age was 15.4 years and 75 per cent of patients were female. The most frequent benign pathologies were nodular goitre (35.6 per cent), follicular adenoma (30.1 per cent), and Graves' disease (28.5 per cent). Among 126 thyroid malignancies, papillary thyroid carcinoma was diagnosed in 77.8 per cent of patients, follicular thyroid carcinoma was diagnosed in 10.3 per cent of patients, and medullary thyroid carcinoma was diagnosed in 8.7 per cent of patients. Lymph node metastases were found in 45.9 per cent of patients with papillary thyroid carcinoma and in 36.4 per cent of patients with medullary thyroid carcinoma. Vascular invasion was found in 62.9 per cent of patients with follicular thyroid carcinoma. The mean tumour diameters were 18, 42, and 13 mm in patients with papillary thyroid carcinoma, follicular thyroid carcinoma, and medullary thyroid carcinoma respectively. Early postoperative recurrent laryngeal nerve injury was seen in 27 of 556 patients (4.9 per cent) (22 of 617 (3.6 per cent) nerves at risk with intermittent intraoperative nerve monitoring and 5 of 237 (2.1 per cent) nerves at risk with continuous intraoperative nerve monitoring). Persistent recurrent laryngeal nerve injury was documented in 4 of 556 patients (0.7 per cent). Early postoperative hypoparathyroidism correlated with Graves' disease, thyroid carcinoma, and lymph node dissection. CONCLUSION Papillary thyroid carcinoma and follicular thyroid carcinoma in children were often advanced at presentation. Persistent or recurrent lymph node metastases were mainly seen in papillary thyroid carcinoma. Overall survival was excellent, but longer follow-up is needed.

Paediatric differentiated thyroid carcinoma: a UK National Clinical Practice Consensus Guideline. Endocr Relat Cancer 2022; 29:G1-G33. [PMID: 35900783 PMCID: PMC9513650 DOI: 10.1530/erc-22-0035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Accepted: 06/23/2022] [Indexed: 11/22/2022]
Abstract
This guideline is written as a reference document for clinicians presented with the challenge of managing paediatric patients with differentiated thyroid carcinoma up to the age of 19 years. Care of paediatric patients with differentiated thyroid carcinoma differs in key aspects from that of adults, and there have been several recent developments in the care pathways for this condition; this guideline has sought to identify and attend to these areas. It addresses the presentation, clinical assessment, diagnosis, management (both surgical and medical), genetic counselling, follow-up and prognosis of affected patients. The guideline development group formed of a multi-disciplinary panel of sub-speciality experts carried out a systematic primary literature review and Delphi Consensus exercise. The guideline was developed in accordance with The Appraisal of Guidelines Research and Evaluation Instrument II criteria, with input from stakeholders including charities and patient groups. Based on scientific evidence and expert opinion, 58 recommendations have been collected to produce a clear, pragmatic set of management guidelines. It is intended as an evidence base for future optimal management and to improve the quality of clinical care of paediatric patients with differentiated thyroid carcinoma.

Abstract
Abstract
Objectives
To discuss management protocol, surgical complications, and outcomes of thyroid carcinoma in children.
Methods
We performed a retrospective analysis including all pediatric patients with thyroid carcinoma who were managed at our institution between January 2011 and January 2021. Data were analyzed regarding demographics, clinical features, operative details, postoperative complications, and survival data.
Results
Thirty-two patients were identified; 26 females (81.25%) and 6 males (18.75%). The median age at operation was 14 years (range: 5–18). Twenty-six (81.25%) patients presented with palpable thyroid swelling. Median tumor size was 3 cm (range: 1–7). Metastatic workup did not detect any pulmonary metastases. Total thyroidectomy was performed in 25 patients (78%), and 16 of them underwent additional bilateral neck dissection (16 had central nodal dissection, and 7 had both central and lateral nodal dissection). Seven patients (22%) underwent hemithyroidectomy, and only one of them had a completion thyroidectomy after 2 weeks. Conservative resection was adopted in six children with similar criteria (tumor size < 1.5 cm in one lobe, no extrathyroid extension, differentiated thyroid carcinoma, no detected lymph nodes). Postoperative complications occurred in eight patients (all had total thyroidectomy) with an overall incidence of 25%. Seven patients had transient morbidities that were managed conservatively (chylous leak n = 1, hypoparathyroidism n = 3, and nerve palsy n = 3). At a median follow-up time of 54 months, four patients had relapsed (all underwent total thyroidectomy). The 5-year OS and EFS were 100% and 87.5%, respectively.
Conclusion
Operative resection for pediatric thyroid carcinoma can be performed with average short-term complications and achieving excellent outcomes. Total thyroidectomy remains the standard procedure of choice in the majority of those patients. However, conservative surgery can be successfully adopted in a well-selected group of children with favorable long-term results as per our findings.

Abstract
Background Pediatric PTC is a rare disease. Although, the prognosis is excellent and the mortality rate is low, the role of prophylactic central neck dissection is still the subject of debate. The aim was to evaluate both the role and safety of prophylactic central neck dissection (CND) in managing pediatric papillary thyroid cancer (PTC), especially in respect of disease-free survival (DFS). Patients and Methods In this retrospective study, we collected 54 pediatric cN0 PTC patients (≤ 18 years of age) who were treated from January 2014 to January 2021 at a high-volume thyroid surgery center. Patients were divided into two groups based on the status of prophylactic CND. We analyzed the factors related to the clinicopathological features and recurrence of PTC in children. Results Of the 54 cN0 patients, 35 underwent prophylactic CND and 19 patients did not undergo prophylactic CND. The two groups were similar in clinical and pathologic features, such as age, gender, tumor size, multifocal status, and follow-up time. The average DFS was 84.4 ± 2.7 months. Log-rank tests on Kaplan-Meier curves revealed that age, gender, tumor size, multifocality, and extrathyroid extension did not relate to DFS time. Furthermore, DFS time was not affected by the extent of thyroidectomy (p=0.07) or RAI treatment (p=0.21). Prophylactic CND was found to increase DFS time for pediatric patients with cN0 PTC (p = 0.003). There was no statistically significant difference in complications such as transient hypocalcemia (p=0.15) and transient recurrent laryngeal nerve injury (p=0.37) between the prophylactic CND group and the no-prophylactic CND group. Conclusion Prophylactic CND was found to be associated with increased DFS and not with increased rates of complications after surgery.

Abstract
CONTEXT Against the background of increasing incidence, pediatric differentiated thyroid carcinoma (DTC) frequently presents with advanced disease and high recurrence rates while prognosis remains excellent. BACKGROUND We investigated the use of a pediatric classification and an adult response to therapy risk stratification for pediatric DTC patients and their implications for adaptation of treatment and follow-up. METHODS Data from patients aged <18 years with a diagnosis of primary DTC, registered with the German Pediatric Oncology Hematology-Malignant Endocrine Tumor registry since 1995, were analyzed. For risk prediction, patients were retrospectively assigned to the American Thyroid Association (ATA) risk groups and evaluated for response to therapy. RESULTS By October 2019, 354 patients with DTC had been reported (median age at diagnosis 13.7 years, range 3.6-17.9) with lymph node and distant metastases in 74.3% and 24.5%. Mean follow-up was 4.1 years (range 0-20.6). Ten-year overall and event-free survival (EFS) rates were 98.9% and 78.1%. EFS was impaired for patients with lymph node and distant metastases (P < .001), positive postoperative thyroglobulin (P = .006), incomplete resection (P = .002), sequential surgeries to achieve total thyroidectomy (P = .042), invasion of capsule (P < .001) and lymph vessels (P = .005), infiltration of surrounding soft tissues (P < .001), tumor multifocality (P < .001), ATA intermediate- and high-risk group (P < .001), and age <10 years (P < .001). Multivariate analysis revealed age <10 years at diagnosis, ATA high-risk level, and poor response to therapy as significant negative prognostic factors for EFS. CONCLUSION Age, ATA risk group, and response to therapy emerged as significant prognostic factors for EFS in pediatric patients with DTC, requiring risk-adapted individualized therapy and follow-up.

Abstract
Pediatric papillary thyroid carcinomas (pPTCs) are often indolent tumors with excellent long-term outcome, although subsets of cases are clinically troublesome and recur. Although it is generally thought to exhibit similar molecular aberrancies as their counterpart tumors in adults, the pan-genomic landscape of clinically aggressive pPTCs has not been previously described. In this study, five pairs of primary and synchronously metastatic pPTC from patients with high-risk phenotypes were characterized using parallel whole-genome and -transcriptome sequencing. Primary tumors and their metastatic components displayed an exceedingly low number of coding somatic mutations and gross chromosomal alterations overall, with surprisingly few shared mutational events. Two cases exhibited one established gene fusion event each (SQSTM1-NTRK3 and NCOA4-RET) in both primary and metastatic tissues, and one case each was positive for a BRAF V600E mutation and a germline truncating CHEK2 mutation, respectively. One single case was without apparent driver events and was considered as a genetic orphan. Non-coding mutations in cancer-associated regions were generally not present. By expressional analyses, fusion-driven primary and metastatic pPTC clustered separately from the mutation-driven cases and the sole genetic orphan. We conclude that pPTCs are genetically indolent tumors with exceedingly stable genomes. Several mutations found exclusively in the metastatic samples which may represent novel genetic events that drive the metastatic behavior, and the differences in mutational compositions suggest early clonal divergence between primary tumors and metastases. Moreover, an overrepresentation of mutational and expressional dysregulation of immune regulatory pathways was noted among fusion-positive pPTC metastases, suggesting that these tumors might facilitate spread through immune evasive mechanisms.

Abstract
Thyroid cancer is a rare malignancy in the pediatric population that is highly associated with disease aggressiveness and advanced disease stages when compared to adult population. The biological and molecular features underlying pediatric and adult thyroid cancer pathogenesis could be responsible for differences in the clinical presentation and prognosis. Despite this, the clinical assessment and treatments used in pediatric thyroid cancer are the same as those implemented for adults and specific personalized target treatments are not used in clinical practice. In this review, we focus on papillary thyroid carcinoma (PTC), which represents 80-90% of all differentiated thyroid carcinomas. PTC has a high rate of gene fusions and mutations, which can influence the histologic subtypes in both children and adults. This review also highlights telomere-related genomic instability and changes in nuclear organization as novel biomarkers for thyroid cancers.
