Predictive Factors for Malignancy in Pediatric Thyroid Nodules: A Comprehensive Analysis from a 26-Year Cohort Study on Clinical, Radiologic, and Cytologic Aspects
To identify clinical and ultrasound features associated with malignancy in pediatric thyroid nodules and describe the clinicopathological characteristics of pediatric thyroid cancer patients.
Approach:
Study Design: Retrospective observational cohort study conducted at Necker Children's University hospital in Paris, France, including patients aged ≤ 18 years with thyroid nodules from 1997 to 2023.
Data Collection: Data extracted from medical records included clinical, laboratory, imaging, and cytopathology features, with a focus on age at diagnosis, family history, symptoms, and ultrasound findings.
Key Findings:
Thyroid nodules in children have a higher malignancy rate (25%) compared to adults (5%), based on the study's cohort.
Key ultrasound features indicating higher malignancy risk identified in the study include solid composition, marked hypoechogenicity, microcalcifications, irregular margins, and increased intranodular vascularity.
The study found that no single ultrasound feature is perfectly sensitive or specific for malignancy in pediatric patients.
Interpretation:
The study emphasizes the need for comprehensive evaluation of clinical and ultrasound features to improve early diagnosis and management of pediatric thyroid nodules.
Limitations:
Exclusion of nodules smaller than 0.5 cm may limit the generalizability of findings.
The study is based on a single-center experience, which may not reflect broader population characteristics.
Conclusion:
The study provides detailed information on pediatric thyroid nodules, which is essential for enhancing diagnosis and management strategies.
