Changing incidence of gastric and oesophageal cancer subtypes in central Switzerland between 1982 and 2007.

Several Western countries have reported a decrease in the incidence of noncardia gastric adenocarcinoma and a strong increase in the incidence of oesophageal and cardia adenocarcinoma. We examined incidence rates of gastric and oesophageal cancer by subsite and histology in Central Switzerland over the last 26 years. Data on biopsy-diagnosed gastric and oesophageal carcinoma incidence during 1982-2007 were obtained from the Cancer Registry of the Institute of Pathology, Lucerne, the Medical Centre for Central Switzerland.
