- New research from prostate and bladder cancer Panoramic datasets offers pathways for optimized patient-centered care
NEW YORK–(BUSINESS WIRE)–Flatiron Health today announced its presence at the American Society of Genitourinary Cancers Symposium happening from February 26-28, 2026, in San Francisco, California. Flatiron’s real-world data and research capabilities are featured across multiple presentations, including 6 research acceptances spanning genitourinary cancers.
A cornerstone of Flatiron’s presence at ASCO GU 2026 is the global prostate cancer and bladder cancer Panoramic datasets, which draw from over 420,000 relevant longitudinal patient records in Flatiron’s network. These prostate datasets specifically unlock high-quality, source-level unstructured and structured EHR data across Germany, the UK, and the US. Built on a common data model across all regions, these datasets enable unprecedented interoperability—allowing researchers to seamlessly analyze patient outcomes and treatment patterns across markets to inform global evidence strategies.
“Recent advancements have fundamentally transformed treatment options for genitourinary cancers, but our research reveals a critical gap: too many patients—particularly those with platinum-ineligibility, non-BRCA mutations, or comorbidities—are not benefiting from these breakthroughs,” said Emily Castellanos, MD, MPH, Senior Medical Director and Head of Research Oncology at Flatiron Health. “Our ASCO GU research, spanning disease states, biomarker status, 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.”
Research highlights include:
- A study demonstrating the need for broader genetic testing and more equitable access to PARP inhibitors for all patients with DNA repair mutations, not just BRCAm carriers, to improve outcomes in advanced prostate cancer
- A study suggesting that selected cisplatin-ineligible patients with muscle-invasive bladder cancer may benefit from chemotherapy despite medical limitations
- A study revealing a critical need for more effective therapy options following Lu177, a treatment recently approved for metastatic castration-resistant prostate cancer
