Abstract
BACKGROUND: There is a paucity of studies reporting long-term survival outcomes for HPV/p16 positive oropharyngeal squamous cell carcinoma (OPSCC). This study aims to compare long-term outcomes of advanced stage p16 positive and negative OPSCCs, treated by surgical and non-surgical modalities. METHODS: OPSCC patients from 1998 to 2012 were identified through a prospectively collected cancer registry. P16 immunohistochemistry was used as a surrogate marker for HPV-OPSCC. Overall survival (OS) and aspiration free survival (AFS) comparisons were made between patients treated with chemoradiation (CRT) versus primary surgery and radiation/chemoradiation (S+RT/CRT) at 5, 10 and 15 years post-treatment. RESULTS: A total of 319 patients were included. P16 positive patients and non-smokers had significantly higher long-term (5, 10 and 15-year) OS. Smokers and p16 negative patients treated with S+RT/CRT had improved long-term OS compared to patients who received CRT. Smokers and p16 negative patients had lower long-term AFS. Multivariate analysis showed improved OS was associated with p16 positivity (HR 0.42, 0.28-0.61) and surgery (HR 0.47, 0.32-0.69), whereas lower OS was associated with ECOG ≥ 2 (HR 2.46, 1.61-3.77), smoking (HR 2.37, 1.41-3.99) and higher stage (HR 1.68, 1.05-2.68). CONCLUSIONS: In smokers and p16-negative OPSCC patients, primary surgery may be associated with improved long-term survival and dysphagia-related outcomes.

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
