BACKGROUND: The presence of mucinous component has been indicated to have a prognostic value in adenocarcinoma. However, little is known regarding the clinicopathological characteristics and prognosis of hilar cholangiocarcinoma (HC) with mucinous component (HCM). METHODS: Between January 1996 and December 2014, a total of 61 HCM patients who underwent curative-intent resection at West China Hospital were retrospectively reviewed. The clinicopathological characteristics and survival of these patients were compared with a large cohort of 217 surgically resected conventional HC patients during the same period. RESULTS: The clinicopathological characteristics of HCM were distinct from conventional HC, including higher CA19-9 levels, larger tumor sizes, less differentiation, and a high frequency of liver parenchyma invasion, portal vein invasion, and lymphovascular invasion. HCM patients showed significantly worse recurrence-free survival (13.4 vs 23.9 months; P = .011) and overall survival (18.2 vs 32.1 months; P = .019) compared with conventional HC patients. Multivariate analysis confirmed liver parenchyma invasion, N stage, surgical margin, and histological grade as independent prognostic factors influencing overall survival in HCM patients. CONCLUSION: HCM showed distinct clinicopathological features, more aggressive biological behaviors, and poor prognosis in comparison with conventional HC. Therefore, the mucinous component is an adverse prognostic factor for HC.
