Gallbladder Cancer Survival Statistics

GITNUXREPORT 2026

Gallbladder Cancer Survival Statistics

Survival for gallbladder cancer can swing from about 10.2% overall 5 year survival in a large US SEER analysis to 60% after resection when lymph nodes are negative, yet it drops to around 30% with N1 to N2 spread. Newer trial results add another sharp contrast, with durvalumab plus gemcitabine and cisplatin lowering the risk of death versus placebo and extending median overall survival in advanced biliary tract cancers.

Gallbladder cancer survival swings dramatically depending on stage and treatment, from a 10.2% 5-year overall survival in a large SEER analysis to 23% in a Korean cohort where lymph node spread was common. Even in resections, lymph node status separates outcomes with reported 5-year survival of 60% for N0 and 30% for N1 to N2, while durvalumab plus gemcitabine and cisplatin showed an overall survival hazard ratio of 0.85 versus placebo. There is also a stark contrast between near zero 5-year survival for unresectable or advanced biliary tract cancers and longer survival signals tied to biomarkers and surgical margins, making these statistics worth sorting carefully.
