Gallbladder
Regional (N1) lymph nodes of the gallbladder are limited to the hepatic hilus (including nodes along the common bile duct, hepatic artery, portal vein, and cystic duct). Metastases to celiac, periduodenal,
peripancreatic, and superior mesenteric artery lymph nodes are considered N2 disease.

Gallbladder
Two views of T2: tumor invading perimuscular connective tissue, with no invasion beyond serosa (illustration below dotted line) or into the liver (above dotted line).

Gallbladder
Two views of T3: tumor perforating the serosa (visceral peritoneum) (below the dotted line) and/or directly invading the liver (above the dotted line).

Gallbladder
T3 may also be defined as tumor invading one other adjacent organ or structure, such as the duodenum (as illustrated), or the stomach, colon, pancreas, omentum, or
extrahepatic bile ducts.

Gallbladder
T4 is defined as tumor invading main portal vein or hepatic artery.

Gallbladder
T4 is defined as invading two or more extrahepatic organs or structures (here, colon and duodenum).

Gallbladder
N1 is defined as metastasis to hepatic hilar (regional) lymph nodes. N2 is defined as metastasis to periaortic, pericaval, superior mesenteric artery and/or celiac artery
lymph nodes.
