    Abstract:
    BACKGROUND: The incidence rates of gastric and oesophageal adenocarcinoma are changing significantly, but little is known about specific sub-sites. AIM: To use a population-based approach to describe the trends in the site-specific incidence of oesophageal and gastric adenocarcinoma. METHODS: Using the Rochester Epidemiology Project, all cases of gastric and oesophageal adenocarcinoma among Olmsted County, Minnesota, residents first diagnosed between 1971 and 2000 were identified (n = 186). Complete in-patient and out-patient records were reviewed and site determined from pathological, surgical, endoscopic and radiological reports. RESULTS: Between the decades of 1971-1980 and 1991-2000, the incidence of oesophageal adenocarcinoma increased significantly from 0.4 to 2.5 per 100 000 person-years. The incidence of adenocarcinoma of the oesophagogastric junction also increased from a rate of 0.6 to 2.2 per 100 000 person-years. The incidence rate of cancer involving the gastric cardia was stable but the incidence of adenocarcinoma involving distal gastric sites declined. Combined oesophageal and oesophagogastric junction adenocarcinoma (4.7 per 1 000 000 person-years) was as common as gastric adenocarcinoma (3.4 per 100 000 person-years) in 1991-2000. CONCLUSIONS: The incidence rates of adenocarcinoma involving proximal gastric sub-sites do not appear to be increasing in a manner similar to those involving oesophageal sub-sites.
