EOD

Extent of Disease (EOD) is a set of three data items that describe how far a cancer has spread at the time of diagnosis. EOD 2018 is effective for cases diagnosed in 2018 and later.

In each EOD schema, valid values, definitions, and registrar notes are provided for

• EOD Primary Tumor
• EOD Lymph Nodes
• EOD Mets
• Summary Stage 2018
• Site-Specific Data Items (SSDIs), including grade, pertinent to the schema

For cancer cases diagnosed January 1, 2018 and later, the NCI SEER program will collect Extent of Disease (EOD) revised for 2018 and Summary Stage 2018. The schemas have been developed to be compatible with the AJCC 8th Edition chapter definitions.

All of the standard setting organizations will collect the predictive and prognostic factors through Site Specific Data Items (SSDIs). Unlike the SSFs, these data items have formats and code structures specific to the data item.

To include EOD in your project, use the following dependency:

implementation 'com.imsweb:staging-client-java-eod-public:x.x.x'

To use the EOD algorithm use the EodDataProvider.

Staging.getInstance(EodDataProvider.getInstance());
