Objective:

To determine the long-term survival and to analyze the factors associated with it in the patients operated on for hilar cholangiocarcinoma (HC) with curative intention.

Method:

Non concurrent cohort study. We included all patients who underwent surgery with curative intent for HC between 2002 and 2016. An analysis of factors associated with survival using Kaplan Meier, log-rank test and Cox regression was performed. A p-value less than 0.05 was considered significant

Results:

Thirty patients were operated on. The median age was 65.5 years (range: 33-84); 24 patients (80%) were male. The surgical margin was negative in 27 patients (90%). Twenty-one patients (70%) presented complications and three patients (10%) died postoperatively. Survival at the year, 5 years and 10 years were 65.7%, 37.3% and 16.6%, respectively. In multivariable analysis, the only factor associated with survival was the T stage (hazard ratio: 0.309; 95% confidence interval: 0.101-0.942; p = 0.03).

Discussion:

Patients operated on for HC with curative intent in our center have adequate long-term survival, with high postoperative morbidity and mortality. The only factor that was associated with survival was T stage.
