Oncology Cohort
Release Version: November 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 November 2025 OMOP population, 217,425 patients met the criteria for cancer cohort.
- Neural Frame: Defined as research-eligible patients with case records in Neural Frame (aka Stanford Cancer Registry).
- Tumor Board encounter: These encounters are defined using the EPIC patient encounter data tables.
- Philips ISPM: Includes genomic testing information from the Philips IntelliSpace Precision Medicine (ISPM) genomics database at Stanford.
- 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.
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.
