Cause of Death in Patients With Well‐Differentiated Thyroid Carcinoma
Bibliographic record
Abstract
OBJECTIVES: The aim of this study is to examine in detail patients dying of well-differentiated thyroid carcinoma. STUDY DESIGN: A retrospective chart review with follow-up. METHODS: Data were collected from 522 consecutive cases of differentiated thyroid carcinoma treated by one endocrinologist and four surgeons at Mount Sinai Hospital, Toronto, Ontario, Canada, from 1964 to 1999. RESULTS: Ten patients died as a direct result of thyroid carcinoma; 19 other deaths were unrelated. Five of 102 patients were men (5%) and 5 of 420 were women (1%); the median age at diagnosis was 68.5 years (range, 49-82 y). No cases were stage I; three, stage II; two, stage III; and five, stage IV. Pathologically papillary carcinoma was found in six of the patients who died, follicular carcinoma in three patients, and Hurtle cell carcinoma in one patient. The causes of death were local invasion or compression of the trachea in two cases and distant metastases in eight patients. Median survival was 3.5 years (range, 1 mo-20 y). CONCLUSIONS: All patients dying of well-differentiated thyroid carcinoma had neck nodes, extrathyroidal spread, or distant metastases at presentation and were older than 49 years of age. Many presented because of their distant metastases. Death resulting from local disease was unusual, with most patients dying of distant metastases.

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.
