It focuses on applying a previously developed predictive tool to new patient cohorts, assessing performance consistency beyond the original development setting. The work supports more reliable risk stratification to guide clinical decision-making in urothelial cancer pathways, emphasizing generalizability and practical use for improving referral and evaluation efficiency in suspected urinary tract malignancy.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/urothelial-cancer-machine-learning-and-external-validation-of-the-identify-risk-calculator-for-patients-with-haematuria-referred-to-secondary-care-for-suspected-urinary-tract-cancer/128783/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/urothelial-cancer-machine-learning-and-external-validation-of-the-identify-risk-calculator-for-patients-with-haematuria-referred-to-secondary-care-for-suspected-urinary-tract-cancer/128783.png","ImageObject",300,407,{"name":92,"@type":93},"Hazel","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-09-22","2026-08-06",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the main purpose of the study described here?","Question",{"text":112,"@type":113},"To externally validate the IDENTIFY risk calculator using a machine-learning approach for patients with haematuria referred to secondary care for suspected urinary tract cancer.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What patient group does the IDENTIFY risk calculator target in this work?",{"text":117,"@type":113},"Patients with haematuria who are referred to secondary care because of suspected urinary tract cancer.",{"name":119,"@type":110,"acceptedAnswer":120},"Why does the study emphasize external validation?",{"text":121,"@type":113},"External validation checks whether the predictive tool performs reliably beyond the original development setting, supporting generalizability for clinical use.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},128783,1786003394,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":39,"category_name":40,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":29,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":44,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":143},1099523882367,"https://ap-avatar.wpscdn.com/davatar_9964176cb1d06d4a9deccf72a44ae3dc","[available at www . science direct . com](available at www . science direct . com)  \njournal homepage: [www . european urology . com/eu focus](www . european urology . com/eu focus)  \nUrothelial Cancer  \nMachine Learning and External Validation of the IDENTIFY Risk Calculator for Patients with Haematuria Referred to Secondary Care for Suspected Urinary Tract Cancer  \nSinan Khadhouria,b,*, Artsiom Hramykac, Kevin Gallagher b,d,e, Alexander Light b,f, Simona Ippolitib,g, Marie Edison b,h, Cameron Alexander b,i, Meghana Kulkarnib,j, Eleanor Zimmermann b,k, Arjun Nathan b,e, Luca Orecchial, Ravi Banthiam, Pietro Piazza n, David Mako, Nikolaos Pyrgidisp, Prabhat Narayan q, Pablo Abad Lopez r, Faisal Nawaz s,  \nTrung-Thanh Trant,u, Francesco Clapsv, Donnacha Hogan w, Juan Gomez Rivas x, Santiago Alonso x, Ijeoma Chibuzoy, Beatriz Gutierrez Hidalgo z, Jessica Whitburn aa, Jeremy Teoh bb,  \nGautier Marcq cc,dd, Alexandra Szostek cc, Jasper Bondadee, Petros Sountoulidesff, Tom Kelsey c, Veeru Kasivisvanathan b,gg, IDENTIFY Study Group y  \na School of Medicine, University of St Andrews, St Andrews, UK;
