The NCI's summary gives separate stage groupings for squamous cell carcinoma and adenocarcinoma, each running from stage 0, also called high-grade dysplasia, where cancer is in the inner lining of the oesophagus wall, through stages I to III to stage IV. Grade (1 to 3, by how abnormal the cells look) enters the stage grouping for early disease. Staging tests include endoscopic ultrasound, CT, PET-CT and MRI. The stage descriptions are those in the National Cancer Institute's PDQ summary, which follows the AJCC tables.","asOf":"2026-11-04","links":[{"label":"National Cancer Institute, Esophageal cancer stages","url":"https://www.cancer.gov/types/esophageal/stages"},{"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":["tnm-staging","ajcc-stage","endoscopy"],"cancers":["esophageal","oesophageal-adenocarcinoma","oesophageal-squamous-cell-carcinoma"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"category":"Clinical"},"route":"/terms/oesophageal-ogj-staging/","neighbours":{"term":[{"id":"ajcc-stage","kind":"term","name":"AJCC stage (TNM staging manual)","route":"/terms/ajcc-stage/"},{"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":"endoscopy","kind":"term","name":"Endoscopy (EGD, EUS, ERCP)","route":"/terms/endoscopy/"},{"id":"tnm-staging","kind":"term","name":"TNM staging","route":"/terms/tnm-staging/"}],"cancer":[{"id":"oesophageal-adenocarcinoma","kind":"cancer","name":"Oesophageal and junctional adenocarcinoma","route":"/cancers/oesophageal-adenocarcinoma/"},{"id":"esophageal","kind":"cancer","name":"Oesophageal cancer","route":"/cancers/esophageal/"},{"id":"oesophageal-squamous-cell-carcinoma","kind":"cancer","name":"Oesophageal squamous cell carcinoma","route":"/cancers/oesophageal-squamous-cell-carcinoma/"}]}}
