In the 8th edition tables reproduced by the NCI, stage I is a tumour limited to the pancreas and smaller than 2 cm with no node or distant spread; stage II is a tumour limited to the pancreas of 2 to 4 cm, or larger than 4 cm or invading the duodenum or bile duct, without spread. Grade by Ki-67 is reported separately and matters as much for treatment.","asOf":"2026-11-04","links":[{"label":"National Cancer Institute, Pancreatic neuroendocrine tumors (islet cell tumors) treatment (PDQ), health professional version: stage information","url":"https://www.cancer.gov/types/pancreatic/hp/pnet-treatment-pdq"},{"label":"American College of Surgeons, AJCC Current Staging System 2026 (which chapters are 8th edition and which Version 9)","url":"https://www.facs.org/media/c5ik5tkr/ajcc-current-staging-system-2026.pdf"}],"tags":[],"related":["net-grade-ki67","ajcc-version-9","tnm-staging"],"cancers":["pancreatic-net"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"category":"Clinical"},"route":"/terms/net-pancreas-staging/","neighbours":{"term":[{"id":"ajcc-version-9","kind":"term","name":"AJCC Version 9 staging","route":"/terms/ajcc-version-9/"},{"id":"staging-systems","kind":"term","name":"Disease-specific staging and risk systems (FIGO, Ann Arbor, IPI, R-ISS, ELN, IMDC)","route":"/terms/staging-systems/"},{"id":"net-grade-ki67","kind":"term","name":"Neuroendocrine tumour grade (Ki-67) and WHO classification","route":"/terms/net-grade-ki67/"},{"id":"tnm-staging","kind":"term","name":"TNM staging","route":"/terms/tnm-staging/"}],"cancer":[{"id":"pancreatic-net","kind":"cancer","name":"Pancreatic neuroendocrine tumours","route":"/cancers/pancreatic-net/"}]}}
