Beginning with cancer cases detected January 1, 2018 and forward, SEER computer system registries in the United States will gather Extent of Disease info. The three primary information items are EOD Primary Tumor, EOD Regional Nodes and EOD Mets. Using these three data products, an EOD TNM T, EOD TNM N and EOD TNM M will be derived, together with an EOD TNM Stage Group based on the AJCC 8th version. The EOD General Instructions provide advice on just how to code EOD. The EOD 2018 Consolidation Manual was established to assist central computer system registries with debt consolidation of EOD information things: EOD Extension, EOD Lymph Nodes, and EOD Mets. The current version of this manual is version 2. 1 to line up with the present EOD version. Please send the question to Ask a SEER Registrar and select EOD if you have any inquiries concerning the EOD Consolidation Manual.
