Meas Value for TNM staging in Oncology


I am new to oncology mapping in OMOP. In Athena, the domain for TNM staging is Meas Value. As per my understanding the TNM value should be mapped to MEASUREMENT and then linked with the condition_concept_id.

Please let me know, if my understanding is not right.


It’s not. All cancer modifiers are pre-coordinated, and of the Domain “Measurement”, e.g. https://athena.ohdsi.org/search-terms/terms/1538036. The Measurement Value contains only “Detected”, “Not detected”, etc.
