Incidence of carcinoma of the oesophagus and gastric cardia. Changes over time and geographical differences.

Abstract

The results show an increasing incidence of adenocarcinoma in both oesophagus and gastric cardia. Squamous cell carcinomas show a more stable development with a slight decrease of incidence. Adenocarcinoma is now the most common histological type of cancer in the oesophageal/cardia region in Sweden. Results also suggest a possible drift in location of adenocarcinoma from gastric cardia towards oesophagus. Overall a higher incidence was found in the male population and no trends in patient age at onset could be found. Squamous cell carcinoma is still slightly more common in urban regions.
