Flatiron Health Brings Three Research Acceptances to WCLC 2026

Real-world evidence on NSCLC treatment patterns and outcomes showcases Flatiron's unified, global oncology engine

NEW YORK--(BUSINESS WIRE)--Flatiron Health today announced its presence at the IASLC 2026 World Conference on Lung Cancer hosted by the International Association for the Study of Lung Cancer, with three research acceptances highlighting real-world evidence that advances precision medicine and treatment optimization in non-small cell lung cancer (NSCLC). The presentations demonstrate how Flatiron's high-quality, longitudinal data reveals clinical insights that shape oncology decision-making across the globe.

"Recent advances have fundamentally transformed treatment options for lung cancers, and our research highlights where and when these novel treatments are having an impact for patients in real-world practice,” said Emily Castellanos, MD, MPH, Senior Medical Director and Head of Research Oncology at Flatiron Health. "Our WCLC research, spanning disease states, biomarker-defined subgroups, and treatment types, illuminates how to translate innovation into practice. By capturing this real-world complexity at scale through our Panoramic Database, we're generating the evidence needed to guide clinicians in a rapidly evolving treatment landscape—enabling them to deliver personalized medicine to any patient that is in front of them.”

Flatiron's research at WCLC 2026 underscores the company's position as the gold standard in oncology intelligence, delivering the trusted insights needed to guide the highest-stakes decisions in cancer care and drug development.

Research highlights include:

• Genomic alterations without approved first-line targeted therapies in patients with NSCLC PD-L1 ≥50% treated with immunotherapy: Real-world evidence revealing treatment patterns and outcomes for patients with high PD-L1 expression who lack approved targeted therapy options, demonstrating how immunotherapy is being deployed in clinical practice and informing precision medicine strategies.
• Real-world outcomes with chemoradiation and durvalumab consolidation in stage III KRAS G12C–mutant NSCLC in the US: Examining real-world treatment effectiveness and durability of durvalumab consolidation following chemoradiation in patients with stage III KRAS G12C-mutant disease, providing evidence on how emerging targeted approaches are translating to clinical outcomes.
• Real-world treatment duration and outcomes among patients with early-stage NSCLC receiving adjuvant osimertinib: A retrospective cohort study analyzing treatment patterns, adherence, and survival outcomes in early-stage NSCLC patients receiving adjuvant osimertinib, revealing how precision medicine is reshaping the adjuvant treatment landscape.

These findings underscore Flatiron's ability to transform patient experiences into actionable intelligence—connecting evidence to practice and enabling clinicians and researchers to make clearer decisions that drive better outcomes.
