Pancreatic Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage Information for Pancreatic Cancer

The staging system for pancreatic exocrine cancer continues to evolve. The importance of staging beyond that of resectable and unresectable is uncertain since state-of-the-art treatment has demonstrated little impact on survival. To communicate a uniform definition of disease, however, knowledge of the extent of the disease is necessary. Cancers of the pancreas are commonly identified by the site of involvement within the pancreas. Surgical approaches differ for masses in the head, body, tail, or uncinate process of the pancreas.

Definitions of TNM

The American Joint Committee on Cancer has designated staging by TNM classification to define pancreatic cancer.[1]

b This also includes the "PanInIII" classification.
TXPrimary tumor cannot be assessed.
T0No evidence of primary tumor.
TisCarcinomain situ.b
T1Tumor limited to the pancreas, ≤2 cm in greatest dimension.
T2Tumor limited to the pancreas, >2 cm in greatest dimension.
T3Tumor extends beyond the pancreas but without involvement of the celiac axis or the superior mesenteric artery.
T4Tumor involves the celiac axis or the superior mesenteric artery (unresectable primary tumor).
