Pancreatic cancer staging
The following stages are used for pancreatic cancer:
- Stage 0 (Carcinoma in Situ)
- In stage I, cancer has formed and is found in the pancreas only. Stage I is divided into stage IA and stage IB, based on the size of the tumor.
- Stage IA: The tumor is 2 centimeters or smaller.
- Stage IB: The tumor is larger than 2 centimeters.
- In stage II, cancer may have spread to nearby tissue and organs, and may have spread to lymph nodes near the pancreas. Stage II is divided into stage IIA and stage IIB, based on where the cancer has spread.
- Stage IIA: Cancer has spread to nearby tissue and organs but has not spread to nearby lymph nodes.
- Stage IIB: Cancer has spread to nearby lymph nodes and may have spread to nearby tissue and organs.
- In stage III, cancer has spread to the major blood vessels near the pancreas and may have spread to nearbylymph nodes.
- In stage IV, cancer may be of any size and has spread to distant organs, such as the liver, lung, and peritoneal cavity. It may have also spread to organs and tissues near the pancreas or to lymph nodes.
