Abstract
To review our Pediatric Endocrinology Division’s experience with differentiated thyroid carcinoma (DTC) we analyzed retrospectively the records of patients with DTC that had been seen between June 1988 and June 2008.
Results: Forty-five patients (median age 13.7 years, 36 female) were diagnosed (papillary: 40, follicular: 5) with DTC presenting as a solitary nodule (n: 25), thyroid nodule with cervical adenopathy (n: 9) and multinodular goiter (n: 11). All underwent total thyroidectomy with resection of suspicious cervical lymph nodes (CLN). DTC was multicentric in 59% and revealed extrathyroidal extension in 44%. Initially, 44% had CLN metastases and 24% distant metastases. All patients underwent thyroid remnant ablation with 131I and suppressive treatment. Median follow-up was 5.1 years with a disease-free survival rate at 5 years of follow-up of 75%. Eleven percent presented recurrences.
Conclusion: Pediatric DTC has an aggressive behavior at presentation. Higher preoperative TSH levels were significantly associated with a more advanced disease at diagnosis. CLT was present concomitantly in a quarter of the patients and further studies are needed to establish differences in these patients’ outcome. Diagnostic approach, total thyroidectomy, 131I treatment and thyrotropin suppression allowed a good progression-free survival rate.
