Description
This data item records the most accurate measurement of a solid primary tumor, usually measured on the surgical resection specimen.
Rationale
Tumor size is one indication of the extent of disease. As such, it is used by both clinicians and researchers. Tumor size that is independent of stage is also useful for quality assurance efforts.
Codes: (See the most recent version of the FORDS manual for additional instructions.)
000 No mass/tumor found
001 1 mm or described as less than 1 mm
002-988 Exact size in millimeters (2mm-988mm)
989 989 millimeters or larger
990 Microscopic focus or foci only and no size of focus is given
