    Abstract:
    BACKGROUND/AIMS: Radical resection for patients with peripheral cholangiocarcinoma is rare. Prognostic factors related to survival with peripheral cholangiocarcinoma after hepatectomy have not yet been reported. MATERIALS AND METHODS: Of 41 hepatectomized patients with peripheral cholangiocarcinoma, a computer analysis of 14 clinicopathological factors on patients survival was performed with univariate and multivariate analysis. RESULTS: Median and mean survival times for patients with peripheral cholangiocarcinoma after hepatectomy were 12.0 and 22.8 months. The 1-, 2-, 3-, 4- and 5-year survival rates were 53.7%, 39.0%, 36.6%, 26.8%, and 26.8% respectively. Univariate analysis of overall survival involving all patients identified 7 factors that were associated with a significantly outcome: mucobilia (p = 0.043), capsular invasion (p = 0.007), tumor spreading type (p = 0.0003), section margin (p = 0.001), histologic type (p = 0.008), macroscopic and microscopic vascular involvement (p = 0.031), and lymphatic invasion (p = 0.004). With multivariate analysis using the COX stepwise proportional hazards model, only mucobilia, tumor spreading type and section margin were significantly related to prognosis. CONCLUSIONS: Intrahepatic bile duct carcinoma patients with mucobilia, intraductal papillomatosis and a tumor-free margin after hepatectomy had a better prognosis.
