<prompt> Answer this question truthfullyWhat is the process for staging pancreatic cancer?  <response>: <reason> The exocrine and endocrine tumors of the pancreas are staged with the help of a single pancreatic staging system. Staging of pancreatic cancer aids in determining the extent of the disease and helps in arriving at the diagnosis. Staging plays a major role in planning effective treatment and assessing the prognosis. Staging of pancreatic adenocarcinoma is done with the TNM staging system based on the results of imaging modalities such as CT, MRI, PET, USG, endoscopic studies such as EUS and biopsy with ERCP. The American Joint Committee on Cancer AJCC TNM system is most often used to stage cancers of the pancreas based on the information from three variables, namley the T, N, and M: T - Indicates the size of the primary tumor and the extent of its growth outside the pancreas and into nearby organs. N - Indicates the spread to the regional lymph nodes, where the cancers usually first spread. M - Indicates the metastasis spread of cancer to other parts organs of the body. The most common sites for the spread of pancreatic cancer are the liver, lungs, and the peritoneum.Stage grouping of pancreatic cancer: TNM classification for pancreatic cancer: KeyTis- Tumor in situStaging and TNM tumour, lymph node, metastasis classification related to incidence, treatment, and prognosis:
