Introduction:

Malignant tumors located in the periampullary region can be ampullary, biliary, pancreatic or duodenal and are a health problem due to their high mortality. Their etio-pathogenesis involves many risk factors, whose clinic and epidemiological behavior is unknown by the population of Matanzas.

Objective:

To determine the clinical-epidemiological behavior of malignant periampullary tumors.

Materials and methods:

A descriptive, prospective study was conducted in 34 patients with diagnosis of malignant periampullary tumors, treated in the Gastroenterology Service of the Clinical-Surgery University Hospital Comandante Faustino Perez Hernandez, of Matanzas, from January to December 2021. Variables such as age group, sex, risk factors and personal pathological history, time of evolution of symptoms and tumor location were studied. The results were collected in a data collection form.

Results:

Male sex and the 50-69 years age group predominated. The most frequent risk factors were coffee consumption, smoking and diabetes mellitus. Jaundice was the most frequent symptom. Most of the patients started symptoms one to three months before the diagnosis. Pancreatic cancer was the most frequent.

Conclusions:

Periampullary tumors predominated in the population older than 50 years. Toxic habits were the most common risk factors. Pancreatic cancer had a higher incidence. Clinical behavior was related to the location of the lesion, the time of evolution of the symptoms, and the risk factors that predominated.
