California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
This field records the presence or absence of clinical evidence of the patient’s tumor as of the Date of Last Tumor Status (AKA – Date of Cancer Status). It is important because it can be used to gauge disease-free survival.
The field applies only to the tumor for which the abstract is submitted, regardless of any other tumors the patient might have.
The value may be different for each primary.
