Differentiated Thyroid Cancer Long-Term Outcomes and Risk Stratification in Pediatric and Adolescent Patients: A...

Area of Science:

• Pediatric Oncology
• Endocrinology
• Cancer Research

Background:

• Differentiated thyroid cancer (DTC) in pediatric patients is rare but significant.
• Pediatric DTC often presents at advanced stages but has favorable long-term outcomes.
• Current management aims to optimize treatment and follow-up strategies.

Purpose of the Study:

• To identify prognostic factors for DTC in patients aged 21 and younger.
• To develop a risk stratification model for pediatric DTC.
• To identify low-risk patients suitable for less radical treatment approaches.

Main Methods:

• Retrospective cohort study of 99 patients (children and adolescents) with DTC.
• Data collected from 1980 to 2024.
• Multivariate regression analysis to identify independent predictors of adverse events and event-free interval (EFI).

Main Results:

• No significant difference in long-term outcomes between children and adolescents.
• More than 10.5 positive lymph nodes and extrathyroidal tumor extension are independent predictors of adverse events and reduced EFI.
• Risk stratification into low-, intermediate-, and high-risk groups showed significant differences in EFI, with no low-risk patients experiencing disease recurrence.

Conclusions:

• Meticulous risk stratification is crucial for predicting DTC outcomes in pediatric patients.
• The identified prognostic factors can guide personalized therapeutic strategies.
• Distinguishing low-risk DTC patients may allow for less aggressive treatment, while high-risk patients require intensified management.
