Field Length: 1
Record the behavior of the tumor being reported. The fifth digit of the morphology code is the behavior code.
Instructions for Coding
· Code 3 if any invasion is present, no matter how limited.
· If the specimen is from a metastatic site, code the histology of the metastatic site and code 3 for behavior
. Gastro-intestinal stromal tumors (GIST) and thyomas are frquently non-malignant. However, they must be abstracted and assigned a Behavior Code of 3 if they are noted to have multiple foci, metastasis, or positive lymph nodes.
Note: The ICD-O-3 behavior code for juvenile astrocytoma (9421/1) is coded as 3. Refer to the section "Case Reporting Requirements."
