Stages of pancreatic intraepithelial neoplasia.
Relative incidences of various pancreatic neoplasm.
|Pancreatic ductal adenocarcinoma (PDAC)
||Glands and desmoplasia
|Pancreatic acinar cell carcinoma (ACC)
||1% to 2%
||1% to 4%
|Pancreatic neuroendocrine tumor
||Multiple nests of tumor cells
|Pre-cancer below for comparison:
Intraductal papillary mucinous neoplasm (IPMN)
||Mucinous epithelial cells. Growth within the pancreatic ducts.
Types of intraductal papillary mucinous neoplasm (IPMN)
Staging of cancers
Stage pancreatic cancers as follows:
||The primary tumor cannot be evaluated.
||No evidence of cancer was found in the pancreas.
||Carcinoma in situ. This includes:
- High-grade pancreatic intraepithelial neoplasia (PanIn-3)
- Intraductal papillary mucinous neoplasm with high-grade dysplasia
- Intraductal tubulopapillary neoplasm with high-grade dysplasia
- Mucinous cystic neoplasm with high-grade dysplasia.
||The tumor is in the pancreas only, and is ≤2 cm in greatest dimension
||Tumor ≤0.5 cm in greatest dimension
||Tumor >0.5 cm and <1 cm in greatest dimension
||Tumor 1–2 cm in greatest dimension
||The tumor is in the pancreas only, and it is >2 cm and ≤4 cm in greatest dimension
||Tumor >4 cm in greatest dimension
||Tumor involves celiac axis, superior mesenteric artery, and/or common hepatic artery, regardless of size
||The regional lymph nodes cannot be evaluated.
||Cancer was not found in the regional lymph nodes.
||Metastasis in 1 to 3 regional lymph nodes.
||Metastasis in 4 or more regional lymph nodes.
||No distant metastasis
||Distant metastasis, including distant lymph nodes. Pancreatic cancer most commonly spreads to the liver, the peritoneum, and the lungs.
