Oncology Cohort

Release Version: August 2025 (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 August 2025 OMOP population, 211,582 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

Data Source	Number of Patients	Percent (%)

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.
