Abstract:

Objective To investigate the clinical characteristics and its prognostic factors for hilar cholangiocarcinoma with exairesis.Methods The clinical data of 58 cases of hilar cholangiocarcinoma were retrospectively analyzed.The Kaplan-Meier method was used to estimate the overall survival and disease specific survival rates for these patients.And the factors that may influence the prognosis and survival of patients were analyzed using univariate(log-rank test)and multivariate Cox proportional hazard models.Results The median survival time was 22 months for all patients.The 1-,3-and 5-year survival rates were 76%,40% and 21%,respectively.Univariate analysis showed that preoperative albumin(P=0.002),intraoperative blood loss(P=0.039),surgical method(P=0.006),histologic differentiation(P=0.001),portal vein encroached(P=0.014),surgical margin(P=0.020)were correlated factors for postoperative survival duration.Multivariate analysis by Cox Proportional Hazard Model showed that surgical method(P=0.022),histologic differentiation(P=0.020)were independent prognostic factors for patients with Hilar cholangiocarcinoma excised.Conclusion Low albumin leve,intraoperative blood loss more than 500mL,low degree of tumor differentiation,portal vein encroached,radical surgery,positive surgical margin are risk factors for total survival of Hilar cholangiocarcinoma.
