- Stimulated postoperative thyroglobulin (sPOTg) is associated with persistent disease in children and adolescents with differentiated thyroid cancer (DTC).
Why this matters
- Prognostic factors are needed for pediatric patients with DTC to guide treatment.
- 100% of patients underwent total thyroidectomy, 90.6% received radioactive iodine therapy.
- After a median follow-up of 5 y, 55.6% of patients were disease free, 22.2% had biochemical disease, and 22.2% had persistent structural disease.
- Lymph node metastasis at diagnosis (P=.003), distant metastasis at diagnosis (P=.010), and sPOTg (P<.001) were associated with persistent disease in univariate analysis.
- A cutoff of 31.5 ng/mL sPOTg had sensitivity and specificity of 100% for predicting disease-free status.
- 32 patients with DTC aged ≤18 y ...
