Description
Derived Summary Stage 2018 is derived using the EOD data collection system (EOD Primary Tumor [772], EOD Regional Nodes [774] and EOD Mets [776]) algorithm. Other data items may be included in the derivation process. Effective for cases diagnosed 1/1/2018+. Please see Summary Stage 2018 Manual for specific schema instructions.
Rationale
The SEER program has collected staging information on cases since its inception in 1973. Summary Stage groups cases into broad categories of in situ, local, regional, and distant. Summary Stage can be used to evaluate disease spread at diagnosis, treatment patterns and outcomes over time.
Note: This data item was included in Standards Volume II, Version 16; however, it was not implemented until 2018.
