The overall survival of IPNB-2 (A) and IPNG-2 (B) were significantly better than that of cholangiocarcinoma and gallbladder adenocarcinoma, respectively. There was no significant difference in overall survival between IPNB and IPNG (C). Multivariate analysis suggested that positive surgical margin (D) and lymph node involvement (E) were independent risk factors of IPNG. However, the independent risk factor of IPNB was invasive carcinoma (F).
