California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
Three new data items have been added in 2016 to collect information on tumor size of the solid, primary tumor at various points in the diagnosis and treatment of the reportable neoplasm. These data fields are: Tumor Size-Clinical, Tumor Size-Pathologic and Tumor Size-Summary. These data fields are independent from one another and have specific, unique coding instructions. Refer to each separate tumor size data item for the specific corresponding coding instructions.
