However, beyond the technical aspects, implementing such a project across a large region like Nouvelle Aquitaine, encompassing three university hospitals, soon to include seven regional hospital centers, and a regional cancer center, has been highly instructive. We would like to share our experience. The success of this project is multifactorial and relies on: (1) Structuring the initiative from the outset around three essential competencies: medical, informatics technology (IT)/biomedical, and administrative. The collaboration among the three university hospitals within a health cooperation group (GCS NovA), balanced governance, and a strong commitment to cooperation (formalized through a collaboration agreement) were key elements; (2) securing funding, with the Regional Health Agency covering 52% of the investment, supplemented by contributions from the university hospitals and research funding from sponsors in Bordeaux; (3) engaging all stakeholders, including technical pathology teams, IT managers, biomedical staff, hospital directors, and pathologists. This is fundamentally a human-centered project, requiring the enthusiasm and expertise of each participant, particularly the technical pathology team, to anticipate challenges and optimize the pre-analytical phase before digitization. After 8 to 16months of a \"big bang\" transition to digital pathology, without denying the questions raised by digitalization, the overall outcome has been highly positive in terms of medical practice, ease of teaching residents, inter-site collaboration, and even turnaround times for results.</p>","PeriodicalId":50969,"journal":{"name":"Annales De Pathologie","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144700293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concurrently, biophysical models elucidate the impact of mechanical and osmotic forces on cyst growth and rupture. Multiscale models, integrating these approaches, connect molecular mechanisms to tissue dynamics, providing powerful tools to unravel the complex interactions driving cyst formation. These advances offer promising perspectives in terms of diagnosis, through genetic and biophysical biomarkers and therapeutics.
