Preoperative Neutrophil-to-Lymphocyte Ratio Predicts Recurrence in HPV-Associated Oropharyngeal Cancer After Transoral Robotic Surgery.

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
objectiveEvaluate the role of preoperative neutrophil-to-lymphocyte ratio (NLR) as a predictor of survival outcomes after transoral robotic surgery (TORS) for human papillomavirus-related (HPV+) oropharyngeal squamous cell carcinoma (OPSCC). STUDY
designSingle-institution retrospective review of patients who underwent TORS for HPV + OPSCC from April 2014 to October 2021 and had a preoperative complete blood count test.
settingTertiary academic center.
methodsPreoperative NLR was calculated from complete blood counts drawn within 1 month prior to surgery. Receiver operating characteristic curves evaluated performance of prognostic markers. Kaplan-Meier estimator and Cox regression analyses were used to evaluate survival outcomes when controlling for confounding variables.
resultsA total of 117 patients were included (85.5% male, 94.0% Caucasian, 59.6 ± 9.1 years old), of which 13 patients (11.1%) recurred at a median of 23.5 ± 23 months, including 7 distant metastases. At the latest follow-up, 90.6% remained alive. On Kaplan-Meier analyses, a preoperative NLR of >2.2 was associated with worse recurrence-free survival (77.1% vs 95.5%, P = .02), whereas overall survival was similar between patients (P = .94). When controlling for demographics, tumor stage, pathologic risk criteria, and adjuvant therapy, NLR > 2.2 remained a significant independent predictor of recurrence on multivariate Cox regression analysis (HR 20.6, 95% CI 1.92-80.7, P = .012).
conclusionWhile OS was similar across groups, a preoperative NLR of >2.2 predicted worse recurrence-free survival in a cohort of patients with HPV + OPSCC who underwent TORS. Future studies may consider integrating NLR into prospective trials as a complementary risk-stratification biomarker.
