"Close Then Clear" Margins in Transoral Resection of p16+ Oropharyngeal Squamous Cell Carcinoma.

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
objectiveStandard 5-mm surgical margins in the oropharynx are challenging due to the intimate relationship with neurovascular structures and patient function. De-escalation of therapy with the acceptance of close surgical margins may improve functional patient outcomes. This study assesses locoregional recurrence with initial close (≤2 mm) margins following transoral surgery for p16+ oropharyngeal squamous cell carcinoma (SCC) with or without re-resection and adjuvant therapy. STUDY
designRetrospective cohort study.
settingCanadian tertiary care center.
methodsRetrospective chart review of all patients who underwent transoral robotic surgery or transoral laser microsurgery with curative intent for p16+ oropharyngeal SCC and had ≤2 mm initial surgical margins with or without re-resection and adjuvant therapy between January 2019 and December 2023. The primary outcome was 2-year locoregional control.
resultsIn total, 80 patients were included; 54 had a 2-year follow-up available. Initial margins were close (≤2 mm) in 44 patients (55%) and positive in 34 patients (42.5%). Re-resection was performed in 67 patients (83.8%). Following re-resections, three patients (3.8%) had positive margins and 77 (96.2%) had close or clear margins. Deep margins were most involved (67.5%). In total, 42 patients (52.5%) received adjuvant (chemo)-radiotherapy. Amongst the 54 patients eligible for 2-year follow-up, one had regional recurrence at 18 months postsurgery, resulting in a 2-year locoregional control rate of 98.1%.
conclusionp16+ oropharyngeal SCC with close initial surgical margins results in low locoregional recurrence rates. Intraoperative re-resection with acceptance of close surgical margins may be an effective strategy to preserve both oncologic safety and functional outcomes.
