Nanopore Sequencing for HPV in Oropharyngeal Squamous Cell Carcinoma and Benign Tonsil Specimens.

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
objectivesHuman papillomavirus (HPV) accounts for the majority of oropharyngeal squamous cell carcinoma (OPSCC) cases in the United States but understanding the prevalence of high-risk HPV in oropharyngeal tissue remains poor. We evaluated nanopore sequencing, a novel rapid, and long-read sequencing platform, on OPSCC tissue and tested it in benign tonsils from pediatric and young adult patients. STUDY
designCross-sectional study.
settingAcademic tertiary referral center.
methodsFormalin-fixed, paraffin-embedded (FFPE) specimens of HPV-positive and negative OPSCC diagnosed from 2013 to 2023 were sequenced on the nanopore MinION platform using an amplicon-based approach. Nanopore sequencing was subsequently performed on FFPE tissue from benign tonsillectomy in patients ages 30 and younger performed from 2016 to 2023.
resultsIn 54 OPSCC cases, nanopore sequencing detected HPV DNA in all 27 HPV-positive specimens with 96% of cases exhibiting high abundance (HPV reads >1000). HPV DNA was also detectable in all 27 HPV-negative specimens, but 89% had a low abundance. By interpreting high HPV abundance as HPV-positive, nanopore sequencing demonstrated a 96% sensitivity, 89% specificity, 90% positive predictive value, and 96% negative predictive value rate. In 150 benign tonsillectomy cases, 27% had HPV DNA detected by nanopore sequencing, all in low abundance, including 37% of patients younger than 10 years old. HPV DNA sequences detected belonged to subtype 16.
conclusionsNanopore sequencing demonstrated high sensitivity and specificity for HPV DNA in FFPE OPSCC tissue. High-risk HPV prevalence in pediatric and young adults may be higher than previously studied.
