Additionally, an expert physician panel convened by EndoscopyNow will host a product theater on Sunday, May 4, at 2:45 p.m. Pacific Time, titled, 'The Time is Now: A Clinical Practice Model to Help Prevent Progression from Barrett's to EAC'
FRIENDSWOOD, Texas, May 02, 2025 (GLOBE NEWSWIRE) -- Castle Biosciences, Inc. (Nasdaq: CSTL), a company improving health through innovative tests that guide patient care, will share new data on its TissueCypher Barrett's Esophagus test via two posters at the Digestive Disease Week® (DDW 2025) Annual Meeting, being held May 3-6 in San Diego. In addition to the product theater, Castle is collaborating with renowned gastrointestinal (GI) experts and the American Society for Gastrointestinal Endoscopy (ASGE) on several educational sessions highlighting the use of TissueCypher to improve the risk stratification and subsequent management of patients with Barrett's esophagus (BE).
'The compelling new data being presented at DDW 2025 underpins the important role that TissueCypher can play in identifying patients with BE at higher risk for progression to esophageal cancer,' said Emmanuel Gorospe, M.D., MPH, board-certified gastroenterologist and GI medical director at Castle Biosciences. 'By empowering clinicians to move beyond the traditional 'wait and see' approach, we're working to help enable more personalized surveillance and intervention strategies for BE patients that can potentially prevent cancer rather than simply trying to detect it early.'
The following posters will be presented at DDW 2025 (all times Pacific Time). Posters will be available on the DDW ePosters site and to conference attendees in the DDW meeting planner and mobile app after 12:01 a.m. on the day of the poster's presentation.
