Patients diagnosed between 2008 and 2021 in a tertiary hospital were stratified into three ME-NBI timing and surveillance patterns: none/late, within 6 months only, and within 6 months with regular surveillance. Among 261 patients, 26% developed second primary neoplasms, and multivariate Cox regression showed that advanced stages and timely regular ME-NBI were independent determinants of overall

This study investigated the impacts of esophageal cancer screening using magnifying endoscopy with narrow-band imaging (ME-NBI) on the outcomes of hypopharyngeal cancer patients.  \nMethods: Patients with hypopharyngeal cancer diagnosed from 2008 to 2021 in a tertiary hospital were reviewed retrospectively. Screening and surveillance using ME-NBI examination of the esophagus were divided into three patterns:  \n(1) ME-NBI never performed or more than 6 months after diagnosis of index primary hypopharyngeal cancer,(2) ME-NBI within 6 months only, and (3) MENBI within 6 months and regular surveillance.  \nResults: A total of 261 were reviewed and 21 (8%) patients were in stage I, 20 (8%) in stage II, 27 (10%) in stage III, 116 (44%) in stage IVA, 65 (25%) in stage IVB, and 12 (5%) in stage IVC. Sixty-seven (26%) patients had SPN (50 esophagus, 10 oral cavity, 3 oropharynx, 2 nasopharynx, 1 larynx and 1 lung) . Among esophageal SPN, 35 (70%) and 15 (30%) patients developed synchronous and metachronous neoplasia, respectively. In multivariate Cox regression analysis, advanced stages III and IV (compared with stages I and II, HR: 1.86, 1.18-2.95, p=0.008), ME-NBI examination of the esophagus received within 6 months and regular surveillance (HR: 0.53, 0.36-0.78, p=0.001) were independent factors affecting the overall survival of patients with hypopharyngeal cancer .  \nFrontiers in Oncology 01 [frontiersin.org](frontiersin.org)  \nDiscussion: Our findings demonstrated that screening and surveillance of esophageal SPN","cbCaipbYEDIfTGa5","https://ap.wps.com/l/cbCaipbYEDIfTGa5","pdf",3204727,"English","# Introduction\n# Methods\n# Results\n# Discussion\n# Keywords","[{\"question\":\"What question does the study address about hypopharyngeal cancer patients?\",\"answer\":\"It assesses whether esophageal cancer screening and surveillance using ME-NBI affects clinical outcomes for patients with hypopharyngeal cancer.\"},{\"question\":\"How were patients grouped for ME-NBI screening and surveillance?\",\"answer\":\"They were divided into three patterns: ME-NBI never performed or performed more than 6 months after diagnosis, ME-NBI performed within 6 months only, and ME-NBI performed within 6 months with regular surveillance.\"},{\"question\":\"What did multivariate Cox regression identify as independent factors for overall survival?\",\"answer\":\"Advanced stages III–IV increased risk compared with stages I–II, while ME-NBI performed within 6 months with regular surveillance was associated with improved overall survival.\"}]","Screening and surveillance of esophageal cancer by magnifying endoscopy with narrow band imaging improves the survival of hypopharyngeal cancer patients | PDF",1789975602,25]
