Collaborative Stage Data Set - Revised 04/07/2013 FINAL
CS Site-Specific Factor 10
Tumor Growth Pattern
- Note 1: Cholangiocarcinoma may be classified by growth pattern. The tumor growth patterns of intrahepatic cholangiocarcinoma include the mass forming type, the periductal infiltrating type, and a mixed type. The periductal infiltrating type of cholangiocarcinoma demonstrates a diffuse longitudinal growth pattern along the bile duct. Limited analyses suggest that the diffuse periductal infiltrating type is associated with a poor prognosis.
- Note 2: Record the presence or absence of an infiltrating periductal component. This information may be obtained from radiology, surgery, or pathology reports.
- Note 3: Only code absence of periductal component if a physician states that periductal component is not present or if the tumor is described as mass-forming only. If diagnostic and/or treatment records are not available, record 999 for unknown.
