Endoscopic features of oral and pharyngolaryngeal papillomas and their role in distinguishing 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
backgroundOral and pharyngolaryngeal papillomas are occasionally detected during esophagogastroduodenoscopy. However, their endoscopic features have not been sufficiently investigated.
aimTo distinguish oral and pharyngolaryngeal papillomas from elevated squamous carcinomas, this study examined their endoscopic features.
methodsForty-seven patients with oral or pharyngeal papilloma participated in this study. The endoscopic characteristics of papillomas were identified by focusing on narrowband and blue laser imaging representations.
resultsPapillomas were classified into three patterns based on their endoscopic features: Salmon roe-like polyps, polyps without capillary transparency, and pinecone-like polyps, with salmon roe-like polyps most prevalent (48.9%). We subsequently analyzed features differentiating papillomas and squamous cell carcinomas in the same region and found that squamous cell carcinomas exhibited at least one of the following three features: Uneven or absent lobulated structure, irregular morphology of capillaries, and coexistence of flat lesions. In contrast, papillomas displayed a uniform lobulated structure, homogeneous or non-visible capillaries, and an absence of flat components. When any of these characteristics were present, two endoscopic specialists evaluated the lesions for the diagnosis of squamous cell carcinoma, with sensitivities of 100% and 97.6% and specificities of 68.9% and 93.3%.
conclusionUnderstanding distinct endoscopic patterns of oropharyngeal papillomas and squamous cell carcinomas provides valuable guidance to endoscopists performing esophagogastroduodenoscopy.
