Transoral robotic surgery for human papillomavirus-positive oropharyngeal squamous cell carcinoma: a retrospective observational study from a UK tertiary centre.
Observational study in The Journal of laryngology and otology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHuman papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (SCC) has favourable oncological outcomes, supporting the use of transoral robotic surgery with risk-adapted adjuvant therapy. While anticipated adjuvant treatment intensity is informed by pre-operative assessment, definitive post-operative histopathology determines final risk stratification.
methodsA single-centre study was conducted at University College London Hospitals of 44 HPV-positive oropharyngeal SCC patients treated with primary transoral robotic surgery and selective neck dissection. Discrepancies between clinical and pathological staging, and their impact on adjuvant treatment recommendations, were assessed.
resultsStaging discrepancies were identified in 38 per cent of patients. Pathological nodal upstaging occurred in 20.5 per cent of patients, commonly caused by higher-than-anticipated nodal burden. Involved surgical margins were present in 70.5 per cent of patients. Overall, definitive histopathology resulted in escalation of anticipated adjuvant treatment intensity in 61 per cent of patients, with 52 per cent reclassified as high-risk disease.
conclusionPost-operative histopathology frequently altered anticipated risk stratification, highlighting the limitations of pre-operative staging and the clinical impact of a surgical-first approach.
