Insights
Thyroid carcinoma (TC) affects children and adolescents, often presenting as a solitary thyroid nodule. Early detection and comprehensive management are crucial for favorable outcomes in pediatric thyroid cancer.
Area of Science:
- Pediatric Endocrinology
- Pediatric Oncology
- Otorhinolaryngology
Background:
- Thyroid carcinoma (TC) is rare in pediatric populations but requires specific clinical consideration.
- Understanding the unique presentation and management of TC in young patients is essential for effective treatment.
Purpose of the Study:
- To characterize the clinical presentation, diagnostic workup, treatment, and outcomes of pediatric and adolescent patients diagnosed with thyroid carcinoma.
- To analyze surgical complications and long-term survival rates in this specific demographic.
Main Methods:
- Retrospective analysis of clinical data from pediatric and adolescent patients diagnosed with TC between January 1, 2000, and March 31, 2010.
- Inclusion criteria involved patients under 18 years of age at the time of diagnosis.
Main Results:
- Twenty-three patients (19 female, 4 male) were identified, with a median age of 17.0 years.
- The most common presentation was a solitary thyroid nodule (60.8%). Differentiated TC, predominantly papillary thyroid carcinoma (PTC, 86.9%), was diagnosed in all patients.
- All patients received thyroxine suppressive therapy, and 20 underwent radioactive iodine (131I) therapy. Despite 7 patients developing metastases, all are alive after a median follow-up of 7.1 years.
Conclusions:
- Thyroid carcinoma is a significant clinical entity in the pediatric population.
- Routine thyroid examinations should be integrated into the standard clinical evaluation of children and adolescents to facilitate early detection.
Objective:
To describe clinical presentation, preoperative study, intervention, histology, surgical complications and follow-up characteristics, and survival in patients with thyroid carcinoma (TC) with less than 18 years at presentation.
Material And Methods:
retrospective analysis of clinical data of all children and adolescents followed in S. João Hospital from January 1, 2000 to March 31, 2010 with histologic diagnosis of TC.
Results:
Twenty-three patients were identified, 19 girls, and 4 boys. Median age at presentation was 17.0 years. Annual incidence was 2.3 cases/year. The main presenting symptom was a solitary thyroid nodule (60.8%). Three (13%) patients had risk factors for TC, 2 of the 3 had previous cervical irradiation. The other was a smoker. Total thyroidectomy was performed in 16 (69.6%), and 10 patients underwent a second surgical procedure. Four (17.4%) patients had postoperative complications. Histologic examination revealed differentiated TC in all, papillary thyroid carcinoma (PTC) in 86.9%, follicular carcinoma in the remaining. All patients received thyroxine suppressive therapy and 20 underwent therapeutic radioactive iodine (131I). During follow-up (7.1 years), 7 out of the 23 patients presented new metastases and needed new treatment. All patients are currently alive.
Conclusions:
TC is a reality in pediatric population, thyroid routine examination should take part in all clinical examination in children and adolescents.
