5.3.3.3 Patient and tumour characteristics
Peripancreatic cancer contains following tumour locations (ICD-10 codes):
• C17.0 for malignant neoplasm of duodenum
• C24.0 for malignant neoplasm of extrahepatic bile ducts
• C24.1 for malignant neoplasm of ampulla of Vater
• C25 for malignant neoplasm of pancreas.
Tumour histology is not used as a variable for risk adjustment and is therefore not
analyzed in this section. For a detailed description of TNM classification and TNM stages
for pancreatic cancer, we refer to KCE report 105. 154
