Suggestions for coidng Rai Staging System for Chronic Lymphocytic Leukemia ( CLL ). I am considering just using the generic LOINC “Other staging classification Cancer Narrative” for now.
The Oncology WG is adding NAACCR schemas as OMOP vocabulary. I assume this includes Rai staging. See https://github.com/OHDSI/OncologyWG/tree/master/ohdsi-naaccr-ingestor. @mgurley do you know?
In the past, we encountered the same issue. We ended up adding a custom 2b+ concept for Rai and other staging systems that were not in the OMOP vocabulary.
