Abstract
OBJECTIVES: 1) Review the incidence of thyroid gland invasion by squamous cell laryngeal carcinoma reported in the literature. 2) Assess the association between thyroid gland invasion and anatomical characteristics of the laryngeal tumor. DATA SOURCES: MEDLINE (1967-2007) and EMBASE (1980-2007). These databases were supplemented with 61 patients from McGill University who underwent total laryngectomy with hemi- or total thyroidectomy from 2001-2006. REVIEW METHODS: Systematic review for series of laryngeal carcinoma that commented on thyroid gland invasion according to tumor subsite and pathological characteristics. Total laryngectomy specimens for primary laryngeal squamous cell carcinoma with concomitant thyroid resection were included in the analysis. RESULTS: In total, eight series (n = 399) were included in the meta-analysis. Thyroid gland invasion was present in 33 laryngectomy specimens (8%); the principal method of invasion of the gland was by direct extralaryngeal extension. Subglottic extension > 10 mm (OR 7.22 [2.05 to 25.46]; P = 0.002), transglottic tumors (OR 3.23 [1.16 to 9.00]; P = 0.025), and subglottic subsite (OR 5.66 [1.34 to 23.87]; P = 0.018) were all significantly associated with thyroid gland invasion. Cartilaginous invasion by tumor was not a significant predictor of thyroid gland invasion (P > 0.05). CONCLUSIONS: Thyroid gland invasion is not a general feature of squamous cell laryngeal carcinoma. When present, it is strongly associated with anteroinferior spread of advanced laryngeal tumors. Thyroidectomy may only be required during total laryngectomy for transglottic tumors, subglottic tumors, and tumors with subglottic extension >10 mm.

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 it
