As adherence to these guidelines remains uncertain, we evaluated adherence by comparing the management of preneoplastic gastric conditions before and after the introduction of MAPS I and II in selected European centers.<\/jats:p>\n                  <jats:p>Patient data were retrieved from nine endoscopy units in seven European countries during three periods: pre-MAPS I (2010\/2011), post-MAPS I (2017\/2018), and post-MAPS II (2022\/2023). Screening and dyspepsia-related endoscopies were included. Data on endoscopies, histopathology, Helicobacter pylori treatment, and surveillance were collected using a standardized form. Adherence to nine MAPS recommendations was assessed, with improvement defined as a \u226510-percentage point increase in guideline-concordant management.<\/jats:p>\n                  <jats:p>A total of 2426 patients were included. Over the years, most centers (57%) improved in seven of the nine recommendations. Virtual chromoendoscopy use improved in six centers, with four reporting its use in &gt;50% of cases. All centers improved in performing biopsies from the antrum and corpus, five conducted random biopsies in nearly all patients, and four performed these plus a biopsy from the incisura in &gt;90% of cases. Endoscopic scores for patient stratification were rarely used, although five centers improved in histological scoring or intestinal metaplasia subtyping. H. pylori treatment recommendations remained high (71%\u2013100%), and endoscopic surveillance adherence improved in 4\/7 centers.<\/jats:p>\n                  <jats:p>Adherence to MAPS guidelines improved in most centers; however, gaps in virtual chromoendoscopy, targeted biopsies, and endoscopic\/histopathological scoring remain, potentially affecting surveillance recommendations. This underscores the need for a more tailored approach to enhance implementation.<\/jats:p>","DOI":"10.1055\/a-2695-1376","type":"journal-article","created":{"date-parts":[[2025,9,3]],"date-time":"2025-09-03T22:48:38Z","timestamp":1756939718000},"page":"1338-1347","source":"Crossref","is-referenced-by-count":8,"title":["Adherence to clinical practice guidelines for Management of epithelial precancerous conditions and lesions in the stomach in Europe"],"prefix":"10.1055","volume":"57","author":[{"given":"Filipa","family":"Fontes","sequence":"first","affiliation":[{"name":"Precancerous Lesions and Early Cancer Management Group, Research Center of IPO Porto (CI\u2010IPOP)\/CI\u2010IPOP@RISE (Health Research Group), Portuguese Institute of Oncology of Porto (IPO Porto)\/Porto Comprehensive Cancer Center (Porto.CCC), Porto, Portugal"},{"name":"Public Health and Forensic Sciences, and Medical Education Department, Faculty of Medicine, University of Porto, Porto, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noa E.
