Behavior

DD_category: 
PUF Data Item Name: 
BEHAVIOR
length: 
1
Allowable values: 
0 - 3
Description: 
Records the behavior of all cases reported to the NCDB. The fifth digit of the morphology code is the behavior code.
Analytic Note: 

This item is the product of the application of the conversion rules expressed in ICDO2-3_SEER.xls (http://seer.cancer.gov/tools/conversion/index.html) for cases diagnosed prior to 2001, which were originally coded according to ICD-O-2, and ICD-O-3 codes reported by facilities for cases diagnosed in 2001 or later.
 
Note: the xls file was modified from that available from the SEER web site – behavior code 1 associated with juvenile astrocytomas (9421) has been changed to 3 by agreement among North American registry standard setters, making it consistent with ICD-O-2.
 
Benign tumors or tumors of uncertain behavior (behavior codes 0, 1) are not reported to the NCDB except for the following sites: meninges (C70._), brain (C71._), spinal cord, cranial nerves, and other parts of central nervous system (C72._), pituitary gland (C75.1), craniopharyngeal duct (C75.2) and pineal gland (C75.3). These were not required to be reported until 2004.
