Castle Biosciences Strengthens Commitment to Esophageal Cancer Awareness Through Collaborative Partnerships

FRIENDSWOOD, Texas, April 08, 2025 (GLOBE NEWSWIRE) -- Castle Biosciences, Inc. (Nasdaq: CSTL), a company improving health through innovative tests that guide patient care, is supporting key educational programs and initiatives throughout the month of April in recognition of Esophageal Cancer Awareness Month. The Company is proudly collaborating with the Esophageal Cancer Action Network (ECAN), the American Foregut Society (AFS) and The Gut Doctor Podcast^LLC to promote esophageal cancer prevention, education and advocacy.

“As esophageal cancer is often diagnosed in its late stages, its five-year survival rate remains alarmingly low at around 20%,”¹ said Emmanuel Gorospe, M.D., board-certified gastroenterologist and medical director, gastroenterology, of Castle Biosciences. “This makes early detection and prevention critical. Through our collaboration with advocacy groups and the gastrointestinal (GI) community, we are committed to raising awareness of esophageal cancer risk factors and providing meaningful support to patients and healthcare professionals alike.”

Detection of esophageal cancer and its precursor, Barrett's esophagus (BE), presents significant challenges because the main symptoms — heartburn and gastroesophageal reflux disease (GERD) —commonly occur in many less serious conditions that typically don't warrant concern. Doctors have very good methods to eliminate precancerous cells in BE patients at risk of developing cancer. The challenge, however, is finding which BE patients among the 1.5 million in the U.S. with the condition are in the 0.5% who will progress to cancer. TissueCypher^® is Castle’s risk-stratification test for patients with BE designed to predict a patient’s individual risk of progression to high-grade dysplasia or esophageal cancer. Knowing which patients are likely to progress to cancer can help physicians treat them earlier, potentially creating an opportunity to save their lives.

Esophageal Cancer Action Network (ECAN)
Castle is collaborating with ECAN through a dedicated Esophageal Cancer Awareness Month sponsorship that encompasses a digital media campaign and awareness kits containing brochures, posters and wrist bands that will be distributed to ECAN supporters seeking to raise awareness about esophageal cancer. The media campaign will emphasize several key points: 1) the link between reflux and cancer, 2) esophageal cancer is preventable, and 3) new technology creates vast opportunities to save lives, particularly in the areas of screening/detection, risk stratification, diagnostics and treatment. Additionally, the campaign will focus on human interest stories featuring those who have been affected by esophageal cancer and experienced this alarming diagnosis.

“Awareness is key to ending this devastating disease that is the fastest increasing cancer diagnosis in American men today and has tripled among young people in recent decades,”^2,3 said Mindy Mintz Mordecai, founder, president and chief executive officer of ECAN. “The heart of our mission at ECAN is to save lives, and we are grateful for the support of our corporate partners and our many supporters who help us carry out this mission through education, prevention and awareness initiatives.”
