Radiotherapy Versus Transoral Robotic Surgery for Oropharyngeal Squamous Cell Carcinoma: Final Results of the ORATOR Randomized Trial
Bibliographic record
Abstract
Radiotherapy (RT) and transoral robotic surgery (TORS) are both curative-intent treatment options for oropharyngeal squamous cell carcinoma (OPSCC). Herein, we report the final outcomes of the ORATOR trial comparing these modalities, 5 years after enrollment completion. We randomly assigned 68 patients with T1-2N0-2 OPSCC to RT (with chemotherapy if node-positive) versus TORS plus neck dissection (± adjuvant RT/chemoradiation). The primary end point was swallowing quality of life (QOL) assessed with the MD Anderson Dysphagia Inventory (MDADI). Secondary end points included overall and progression-free survival (OS, PFS), adverse events (AEs), and other QOL metrics. The primary end point has been previously reported (Nichols 2019). In this report, the median follow-up was 5.1 years (IQR, 5.0-5.3 years). MDADI total scores converged by 5 years and were not significantly different across the follow-up period ( P = .11). EORTC QLQ-C30 and H&N35 scores demonstrated differing profiles, including worse dry mouth in the RT arm ( P = .032) and worse pain in the TORS arm ( P = .002). Grade 2-5 AE rates did not differ between arms (91% [n = 31] v 97% [n = 33] respectively, P = .61), with more neutropenia and hearing loss in the RT arm, and more dysphagia and other pain in the TORS arm based on grades 2-5 (all P < .05). There were no differences in OS or PFS. In conclusion, toxicity and QOL profiles differ in some domains between RT and TORS, but oncologic outcomes were excellent in both arms. Choice of treatment should remain a shared decision between the patient and their providers.

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.
