Figure 1 Survival curves of cystic duct cancer based on T staging system of gallbladder cancer or extrahepatic cholangiocarcinoma. A: Overall survival (OS) based on the gallbladder cancer (GC) system; B: Cancer specific survival (CSS) based on the GC system; C: OS based on the extrahepatic cholangiocarcinoma (EC) system; D: CSS based on the EC system. Blue line: T1-2 group; green line: T3-4 group. OS: Overall survival; GC: Gallbladder cancer; EC: Extrahepatic cholangiocarcinoma; CSS: Cancer specific survival.
