FLATIRON HEALTH ANNOUNCES RESEARCH TO BE PRESENTED AT ASCO 2025

• Flatiron’s 2025 ASCO research showcases the power of longitudinal, real-world oncology data and innovative AI-driven methodologies to generate actionable evidence, address health equity, and accelerate progress in cancer care and clinical research.

Flatiron Health today announced 14 abstracts leveraging its high-quality real-world oncology data have been accepted for poster presentation and online publication at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago. These studies exemplify Flatiron’s commitment to advancing cancer research and align with this year’s ASCO theme, “Driving Knowledge to Action: Building a Better Future,” by delivering critical evidence to inform and improve patient care.

“AI and related technologies have enabled us to unlock data and insights from our entire network of over five million people with cancer, providing unprecedented scale, efficiency, and innovation for both real-world evidence generation and clinical trial execution,” said Stephanie Reisinger, Senior Vice President & General Manager, Real-World Evidence. “Our research accepted at this year’s ASCO demonstrates our lasting commitment to deliver actionable evidence and improve care for every person with cancer.”

Highlights include:

• a poster presentation utilizing advanced machine learning models to identify a cohort of over 195,000 to complete the largest real-world study to date examining ctDNA testing in early stage breast cancer
• an abstract assessing how often PSMA-PET scans were used among non-Latinx/Hispanic White, Black, and Latinx patients with metastatic prostate cancer
• an abstract demonstrating the potential of a centralized, tech-enabled screening service to make clinical trial enrollment and more efficient, particularly in community oncology settings

Schedule a meeting with Flatiron Health at ASCO 2025, and learn more about our abstracts and events, including workshops and panels.
