Carcinoma of the gallbladder: staging, treatment, and prognosis
The 1976 paper that first staged gallbladder cancer by how deeply it had grown through the wall, noting that almost every case had been found by chance during gallstone surgery.
Overview
Sixty-six cases from two Virginia hospitals were staged by depth of invasion and spread and graded histologically, and survival was correlated with both; results agreed with 399 reported cases in the literature that could be staged by depth of invasion. 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.
- Depth of invasion correlated with survival in 66 cases and 399 literature cases.
- Essentially all cases were incidental findings at surgery for gallstones.
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.
