Description
This data item stores the Derived Rai stage value derived from the values coded in the following SSDIs for the Lymphoma-CLL/SLL schema (9823/3).
* Lymphocytosis [3885]
* Adenopathy [3804]
* Organomegaly [3907]
* Anemia [3811]
* Thrombocytopenia [3933]
The Rai stage is only applicable for Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL) (9823/3) cases where the primary site is bone marrow (C421). For cases with a primary site other than bone marrow (C421), the derived Rai stage will be 8 and all the SSDIs will be coded to 5.
Derivation will be run on all cases diagnosed 1/1/2018 and forward.
Rationale
The Derived Rai stage can be used to evaluate disease spread at diagnosis, treatment patterns and outcomes over time.
