Young age is associated with increased rates of residual and recurrent paediatric differentiated thyroid carcinoma
Bibliographic record
Abstract
Summary Objective Differentiated thyroid carcinoma is rare in young children. There are conflicting data as to whether disease in this age group differs from that in adolescents and specifically, if it is more aggressive. Current practice guidelines do not differentiate treatment between these groups, but speculate that differences may exist. We sought to compare clinical features, treatment and outcomes between children (<12 years) and adolescents (12‐18 years) with thyroid nodules and thyroid malignancy over a 20‐year period. Design Retrospective case series at a single tertiary care hospital. Patients A total of 177 children 0‐18 years of age at the time of diagnosis of a thyroid nodule and/or malignancy between 1992 and 2012. Results There was a significantly higher female‐to‐male ratio in patients 12‐18 years with benign and malignant nodules compared to those under 12. There was no difference across age groups with respect to cytology or histology, size, surgical approach or nodal status. Younger patients had a higher lymph node ratio. Younger patients received a higher cumulative dose of radioactive iodine (97.6 mCi/m 2 ) vs older patients (75.9 mCi/m 2 ) and had higher rates of pulmonary metastatic disease, although the differences did not achieve significance. Finally, children were less likely than adolescents to achieve a state of undetectable disease and fewer of the younger children remained disease‐free. Conclusions Despite comparable apparent initial disease burden and treatment, younger children have poorer outcomes when compared to adolescents, even in the absence of nodal metastases and thus may warrant intensification of primary therapy and/or tumour surveillance.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
