Tumor Board

Summary:

Tumor Board encounters are defined using the OMOP visit_occurrence table, where the source value for the visit contains the phrase ‘tumor board’. Specifically, Thoracic Tumor Board patients are identified based on their primary site descriptions in the Neural Frame diagnoses data, which include diagnoses of lung, bronchus, or thymus cancers in addition to having a Tumor Board encounter.

Note: Thoracic Tumor Board definition will be narrowed further due to observations from cross-comparison between encounter data in Epic Hyperspace versus Epic Clarity.

As of August 2025, From 13,880 patients with thoracic cancer, 2,748 also had a Tumor Board encounter.

Tumor Board Encounter

Please note that starting in 2018, Stanford Cancer Center standardized and rationalized the tagging of tumor boards in the EHR.

Neural Frame Case Status

The Stanford Cancer Registry keeps track of every cancer case at Stanford and uses the case status variable to monitor each case’s progress. The major categories are: Completed, Not Reportable, and Incomplete.

  • Not Reportable cases refer to cases that are not reportable to the state per cancer registry rules, or those that have already been abstracted.

  • Incomplete cases are reportable and have been abstracted, but are marked as incomplete due to pending treatment information or unresolved edit errors. These edits can arise for a variety of reasons, such as version changes by the state registry or code updates by standard-setting agencies.

  • Completed cases are reportable, have been fully abstracted, and have passed all edit checks. These cases are transmitted to the state.

Please note that the Incomplete case status is eventually updated to either Completed or Not Reportable.

The distribution of case status for Thoracic Tumor Board encounter patients are listed below:

Case Status Number of Patients
Complete 2,289
Not Reportable 309
Incomplete 150
