Tumor Size Summary

PUF Data Item Name: 
Tumor_Size_Summary_2016
NAACCR Item #: 
756
Diagnosis Years Available: 
2016 and later
length: 
3
Allowable values: 
000-990, 998, 999
Description: 
Describes the most accurate measurement of a solid primary tumor, usually measured on the surgical resection specimen. Describes the largest dimension of the diameter of the primary tumor in millimeters.
Registry Coding Instructions: 

Refer to the instructions in the 2016 FORDs manual,page 142, at https://www.facs.org/~/media/files/quality%20programs/cancer/ncdb/fords%...

Analytic Note: 

This variable was added as a FORDs item in 2016, replacing the Collaborative Stage Tumor Size variable collected in 2004-2015 (CS_Tumor_Size). Use the CS_TUMOR_SIZE variable for 2004-2015 diagnosis years, and the Tumor_Size_Summary_2016 for cases diagnosed in 2016 and later. This field is blank for melanoma of the skin. Use CS Site Specific Factor #1 to obtain Breslow’s depth for melanoma of the skin. The codes for Tumor Size Summary are slightly different from those in the CS_Tumor_size variable.
