      Objectives: The objective of the present investigation, was, to find the mortality of the pancreatic adenocarcinoma, and to identify the factors related to this, in a specialized hospital in Lima, Peru. Materials and methods: This is a retrospective cohort field study. All medical records, from October 2008 to April 2015, were reviewed at a national reference hospital in Lima, Peru. This study included all the 18 –year- olds, with a diagnosis of pancreatic adenocarcinoma, confirmed by a pathological anatomy. The independent variables were, age, sex, alcohol and tobacco consumption, history of type 2 Diabetes Mellitus, arterial hypertension, presence of metastases, tumor location and plasma level of Ca 19.9; And the dependent variable was the mortality defined by the time since the diagnosis, to the time of death, or the date when the RENIEC was revised, October 25. Data was processed in Microsoft Excel 2016, and the statistical analysis was performed using STATA 12.0. In the bivariate analysis, we used Log-Rank for categorical variables, and the Kaplan Meier analysis for survival. For the multivariate analysis, we worked with the Cox regression, adjusting it by a statistic model. Results: 48.8% were male, the mean age was 66 years, 21.1% used tobacco, 25.9% used alcohol and 22.9% had a history of DM2. The most frequent location was in the head of the pancreas, 75.8% was diagnosed in stage IV and metastasis was evident in the 31.1%. The 64.8% of patients presented Ca 19.9 ≥ 37 IU/mL and 71.5% underwent surgical operation. Mortality at one year was 65%. In the bivariate analysis, the presence of metastasis, the handling received and the plasma level of Ca 19.9, showed an association with mortality at one year. However, in the final multivariate model, only the presence of metastases (HR: 2,38; p=0,001), remained associated. Conclusions: The mortality of adenocarcinoma of the pancreas in Peru, at one year is 65 %, and the presence of metastases is associated with greater mortality, at one year.
