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 July 2025, From 12,833 patients with thoracic cancer, 2,398 also had a Tumor Board encounter.

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 | 2,022 |
| Not Reportable | 252 |
| Incomplete | 124 |
