Oncology Cohort

Release Version: February 2026 (IRB76049)

Population Summary

Patients are included in the Oncology-OMOP dataset if they have a case in the Neural Frame Stanford Cancer Registry (regardless of case status) or if they have a tumor board encounter in Epic Clarity.

As of the February 2026 OMOP population, 222,003 patients met the criteria for cancer cohort.

• Neural Frame: Defined as research-eligible patients with case records in Neural Frame (aka Stanford Cancer Registry).
  • Neural Frame Metrics
• Tumor Board encounter: These encounters are defined using the EPIC patient encounter data tables.
  • Tumor Board Metrics
• Philips ISPM: Includes genomic testing information from the Philips IntelliSpace Precision Medicine (ISPM) genomics database at Stanford.
  • Philips ISPM Metrics
• OMOP Image Occurrence: The OMOP image occurrence table captures records of medical imaging events at the series level providing a path to deidentified DICOM images.
  • Image Occurrence Metrics
• OMOP Variant Occurrence: The OMOP variant occurrence table contains records of genomic variants identified via the STANFORD ACTIONABLE MUTATION PANEL FOR SOLID TUMORS (STAMP) test, sourced from Epic Genomics Suite (August 2025 onwards).
  • Variant Occurrence Metrics
• OMOP Whole Slide Imaging: The OMOP whole slide imaging table contains records of digitized pathology slides and currently, the table contains manually scanned slides that have been deidentified and converted into TIFF and JSON file formats.
  • Whole Slide Imaging Metrics
• Data Coverage Trends: Longitudinal view of data evolution across all platforms from February 2025 to February 2026.
  • Data Coverage Trends

Data Source	Number of Patients	Percent (%)
Oncology OMOP (Cohort)	222,003	100
• With Tumor Board Encounter	27,118	12
• With Image Occurrence	199,004	90
Neural Frame	218,411	98

Overlap between Data Sources

The following plot represents patients overlap between different data sources:

• The connected dots in the middle show which combinations of data sources exist

• The bars show how many patients are in each combination

For example, if dots are connected for “Oncology OMOP” and “Neural Frame”, the bar above shows how many patients are in both sources.
