Bile Duct Cancer Statistics

Bile duct cancer still causes about 12,000 deaths worldwide each year, yet treatment outcomes have shifted with durvalumab plus gemcitabine and cisplatin becoming a new first line option after TOPAZ 1 and with ABC 02 extending progression free survival to 8.0 months. This page brings together risk and biomarker frequencies like PSC linked lifetime risk around 10 to 15% and FGFR2 fusions in roughly 10 to 16%, along with CA19 9 and targeted therapy results, so you can see what matters most from diagnosis through advanced care.

About 12,000 people die from bile duct cancer every year worldwide, and the latest treatment trials have been rewriting what “standard care” can look like for advanced disease. Median outcomes can shift dramatically, such as 8.0 months progression free survival with gemcitabine plus cisplatin versus 5.0 months with gemcitabine alone, and durvalumab added to gemcitabine plus cisplatin after TOPAZ-1 improved overall survival. Meanwhile, tumor markers, risk factors, and genomic targets like FGFR2 fusions and IDH1 mutations do not affect every patient the same way, and that inconsistency is exactly where the statistics get most interesting.

Directional

Risk Factors & Biomarkers Interpretation

In Bile Duct Cancer, recognizable risk factors and biomarkers converge on a clear pattern where about 10% to 15% of people with primary sclerosing cholangitis develop cholangiocarcinoma and common molecular signals like FGFR2 fusions in roughly 10% to 16% of cases and CA19-9 elevated in 50% to 70% at baseline help identify who is at higher risk and often facing poorer prognosis.

Epidemiology

12.1% of all cancer deaths globally were from bile duct cancer in 2020 (C22.1–C22.0 combined cancer sites, depending on mapping), based on GLOBOCAN 2020 estimated mortality shares[17]

Directional

Epidemiology Interpretation

Globally, bile duct cancer accounts for 2.1% of all cancer deaths in 2020, while in the United States extrahepatic disease shows a low incidence of about 0.7 per 100,000, and this relative rarity is reflected in the epidemiology alongside the fact that survival after curative surgery for perihilar cholangiocarcinoma varies widely from roughly 20% to 50% at 5 years.
