California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures for Hospitals
For cases diagnosed January 1, 2010 and forward, or following installation of CSv2 software, CS Site-Specific Factor items (7-25) have been added to code additional site-specific information needed to derive TNM or AJCC stage, or to code prognostic factors that have an effect on stage or survival. This data item belongs to the Collaborative Stage (CS) Data Collection System. The Collaborative Stage Data Collection System is based on the AJCC Cancer Staging Manual, 6th and 7th editions.
The Collaborative Stage Data Collection System provides a single uniform set of codes and rules for coding extent of disease (EOD) and stage information to meet the needs of all of the participating standard setters. When CS data items are coded, a computer algorithm provides the derivation for T, N, M, and stage.
To code, see the most current version of the Collaborative Stage Data Collection System Manual and Coding Instructions for rules, site-specific codes, and coding structures.
Additional educational information is available in Part 1- Section 2: Lab Tests, Tumor Markers and Site-Specific Factor Notes.
For CS SSF data items not required by the CCR, enter code 988. For CS SSF data items required by the CCR with an unknown value, enter code 999.
Refer to Volume 1, Appendix Y, for the list of CS Site-Specific Factors required by the CCR by schema.
The following CSv2 data items are required effective with cases diagnosed January 1, 2010 and forward:
Although Collaborative Staging has been required by the CCR since 2004, effective with cases diagnosed January 1, 2008 and forward, SEER expanded the requirement to also include the CS Evaluation fields.
The following CS fields are required effective with cases diagnosed January 1, 2008 and forward:
