Flatiron’s presence at ESMO AI demonstrates deep methodological expertise in AI and machine learning applications across global markets and showcases the possibility of trustworthy LLM-extracted real-world data at scale.
Flatiron Health today announced its presence at the European Society For Medical Oncology AI & Digital Oncology Congress 2025 (ESMO AI) taking place on November 12-14 in Berlin, Germany. Flatiron’s experts will be presenting five pieces of research, in addition to leading the speaking session, “The VALID Framework for LLM-Extracted Oncology Data Quality: Comprehensive methodology for evaluating LLM-extracted real-world oncology data quality.”
“Our research presented at ESMO AI demonstrates how LLM-extracted real-world data can be rigorously validated across diverse healthcare systems and countries, empowering our partners to generate credible, fit-for-purpose evidence that informs and advances care and research worldwide,” said Nathan Hubbard, Chief Executive Officer at Flatiron Health. “Flatiron’s team of experts continues to demonstrate what responsible AI in oncology looks like—advancing the field through methodological rigor, privacy-preserving approaches, and the frameworks that make AI trustworthy at scale."
Research highlights include:
- The company's first published research exploring the development of digital twin modeling that incorporates LLM-extracted clinical context to enable more personalized survival predictions and treatment planning.
- Multiple studies advancing the use of LLMs in extracting real-world oncology data through validation and quality evaluation across tumor types, healthcare systems, and countries.
- Applications of the company’s Validation of Accuracy for LLM/ML-Extracted Information and Data (VALID) Framework data quality framework, the industry's first comprehensive approach to evaluating AI-extracted real-world data quality.
