a. Histologic confirmation includes tumors classified as diagnosis confirmed by: positive histology, positive cytology, positive histology plus – positive immunophenotyping and/or positive genetic studies, or positive microscopic confirmation, method not specified.

b. Completeness is defined as having an assigned code that corresponds with a WHO grade as defined by the American Joint Commission on Cancer’s Collaborative Staging schema.

c. Radiation is defined using a recoded variable based on NAACCR Item #1360 (http://datadictionary.naaccr.org/default.aspx?c=10#136). Completeness is defined as having a value other than ‘none’ or ‘unknown.’

d. Surgery is defined using a recoded variable based on NAACCR Item #1290 (http://datadictionary.naaccr.org/default.aspx?c=10#1290). Please see the SEER site-specific surgery codes for more information on coding for this variable (https://seer.cancer.gov/archive/tools/SEER2003.surg.prim.site.codes.pdf). Completeness is defined as having a value other than ‘unknown.’
