Impact of p16 expression, nodal status, and smoking on oncologic outcomes of patients with head and neck unknown primary squamous cell carcinoma
Bibliographic record
Abstract
BACKGROUND: The prognostic significance of human papillomavirus (HPV) in the context of head and neck squamous cell carcinoma (HNSCC) of cancer of unknown primary (CUP) origin is unclear. METHODS: Patients treated for CUP at the Princess Margaret Cancer Centre between 2001 and 2013 were stratified by p16 status and retrospectively reviewed. RESULTS: Of the 73 patients included, those with p16-positive tumors (63%) had less advanced nodal status (N1-N2b; 52% vs 89%; p = .035) and less aggressive treatment. Patients with p16-positive tumors had improved 3-year disease-free survival (DFS; 79% vs 56%; p = .012) independent of nodal status and treatment in multivariable analysis (hazard ratio [HR] = 0.27; 95% confidence interval [CI] = 0.08-0.95). CONCLUSION: Among patients with CUP, p16-positive status is an independent predictor of DFS but not overall survival (OS). © 2016 Wiley Periodicals, Inc.

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.
