Abstract

Purpose

The extent of surgery for pediatric papillary thyroid carcinoma is debatable. The aim of this study was to evaluate the feasibility of offering pediatric patients a tailored surgical approach based on certain clinical features.

Methods

A national multicenter retrospective review of 250 pediatric patients treated for papillary thyroid carcinoma in a 14-year period was performed. Outcomes of interest included tumor-related features, type of surgery, surgical morbidity, disease-free and overall survival rates. Recurrence was thoroughly analyzed with particular focus on how it correlated with certain patient- and tumor-related features.

Results

The majority of patients (58.8 %) had tumors >2 cm in size. Nodal involvement occurred in 115/250 (46 %) patients and distant metastasis in 4 % (10/250). Total thyroidectomy and lobectomy were performed in 90.4 % (226/250) and 9.6 % (24/250) of patients, respectively. The overall rate of surgical complications was 20.8 % (52/250). These included transient and permanent hypoparathyroidism (13.6 and 4.4 %, respectively), and vocal fold palsy (2.8 %). All surgical complications occurred exclusively in the total thyroidectomy group. The rate of recurrent disease was 12 % (30/250) with the vast majority of recurrences (96.6 %) occurring in the total thyroidectomy group. The risk of recurrence correlated significantly with certain tumor-related features (size > 2 cm, multifocality, extrathyroidal invasion, nodal positivity, and distant metastasis). However, it did not correlate with the patient’s age or sex. Overall survival was 100 %.

Conclusion

Pediatric patients are likely to benefit from a tailored surgical strategy. Uniformly offering patients total thyroidectomy seems to be an overly radical approach.
