This article features an executive conversation between MITRE's CTO/CMO Dr. Jay Schnitzer and AWS's Valerie Delva discussing healthcare data standardization and interoperability for cancer treatment and beyond.

• MITRE develops mCODE, a standardized data model for cancer to unlock siloed EHR data
• Lack of consistent EHR standards across vendors prevents data interoperability and reusability
• White House 2022 order mandates public access to federally-funded research data immediately
• Cloud infrastructure is essential for managing scale and complexity of population-level health data
• CODEX initiative has 200+ organizations adopting mCODE for expanded cancer data access
• Key challenges include patient consent, data ownership, privacy, and social determinants integration
• Aligning stakeholder incentives across patients, providers, payers, and researchers is critical
• Access to millions of patient records could revolutionize clinical trials and personalized treatment

The conversation emphasizes that standardized, interoperable health data at scale could transform healthcare outcomes through better clinical decision-making and research, requiring cloud technology and ecosystem-wide alignment.
