The authors describe a simple method combining staging and histological grade applicable to every surgically removed gallbladder cancer. Essentially all carcinomas in the series were incidental findings at surgery for gallstones, which the authors suggest explains a relatively high proportion of superficial carcinomas cured by cholecystectomy.","asOf":"2026-09-24","links":[{"label":"Cancer 1976","url":"https://doi.org/10.1002/1097-0142(197601)37:1<141::AID-CNCR2820370121>3.0.CO;2-Y"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/1247951/"}],"tags":["gallbladder-evidence"],"related":[],"cancers":["gallbladder"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":["tnm-staging","incidental-gallbladder-cancer"],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"journal":"Cancer","year":1976,"doi":"10.1002/1097-0142(197601)37:1<141::AID-CNCR2820370121>3.0.CO;2-Y","pmid":"1247951","authors":"Nevin JE, Moran TJ, Kay S, King R.","paperType":"observational","findings":["Depth of invasion correlated with survival in 66 cases and 399 literature cases.","Essentially all cases were incidental findings at surgery for gallstones."],"whatItMeans":"Depth of invasion has been the organising principle of gallbladder cancer staging ever since, through the TNM editions to the 2017 T2a/T2b split; and the observation that most cases are incidental was already true fifty years ago.","caveats":["Small historical series.","Pre-TNM staging scheme, superseded."],"changedPractice":true,"participants":66},"route":"/key-papers/paper-nevin-gallbladder-carcinoma-staging-cancer-1976/","neighbours":{"cancer":[{"id":"gallbladder","kind":"cancer","name":"Gallbladder cancer","route":"/cancers/gallbladder/"},{"id":"incidental-gallbladder-cancer","kind":"cancer","name":"Incidental gallbladder cancer (found after cholecystectomy)","route":"/cancers/incidental-gallbladder-cancer/"}],"term":[{"id":"tnm-staging","kind":"term","name":"TNM staging","route":"/terms/tnm-staging/"}],"roadmap":[{"id":"gallbladder-cancer-roadmap","kind":"roadmap","name":"Gallbladder cancer roadmap: from a chance finding at gallstone surgery to a disease with its own trials","route":"/roadmaps/gallbladder-cancer-roadmap/"}]}}
