California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
Efforts to transition away from The Collaborative Stage Data Collection System will occur, beginning with cases diagnosed January 1, 2016 and forward. However, in order to transition without losing valuable data, a continued collection of information regarding related biomarkers and prognostic factors will need to occur.
The California Cancer Registry (CCR) will require the following Collaborative Stage (CS) data items to be collected:
Required Site Specific Factors
Regional Nodes Positive
Regional Nodes Examined
Lymph-vascular invasion
For historical coding instructions, please access the version of the California Cancer Reporting Standards, Volume I corresponding to the date of diagnosis in the abstract. Volume I can be accessed at http://www.ccrcal.org/Cancer_Reporting/Registrar_Resources/Reporting_Cancer_Cal.shtml.
