Thyroid nodules and cancers in children.

Area of Science:

• Pediatric Endocrinology
• Oncology
• Genetics

Background:

• Thyroid nodules occur in 1-1.5% of children, with a fourfold higher risk of malignancy compared to adults.
• Differentiated thyroid carcinoma is the most common pediatric endocrine tumor, representing 0.5-3% of childhood cancers.
• The thyroid is a common site for secondary neoplasms in children treated with radiation therapy.

Purpose of the Study:

• To provide a comprehensive review of pediatric thyroid carcinoma.
• To discuss predisposing factors, genetics, pathology, pathogenesis, clinical presentation, and management.
• To address controversial aspects of radioiodine therapy in children.

Main Methods:

• Literature review of pediatric thyroid carcinoma.
• Synthesis of information on risk factors, genetics, and pathology.
• Analysis of treatment and follow-up strategies.

Main Results:

• Pediatric thyroid carcinoma literature is less complete than adult literature due to rarity.
• Differentiated thyroid carcinoma is the predominant type in children.
• Radioiodine therapy in children presents controversial aspects requiring discussion.

Conclusions:

• Early identification and management of pediatric thyroid nodules are crucial due to higher malignancy risk.
• A comprehensive understanding of pediatric thyroid cancer is essential for effective treatment and follow-up.
• Further research and discussion are needed regarding optimal therapeutic strategies, including radioiodine therapy.
