BACKGROUND The rise in adenocarcinoma (AC) of the esophagus has been reported in several papers. However, the results are only comparable to a limited extent, because they are based on differing periods and different computational methods. The purpose of the current investigation was to collect the available data and to analyze them in a unified manner. METHODS The authors requested data on the incidence of AC of the esophagus for each year since 1960 from 43 tumor registries in North America, Europe, and Australia. The data from 22 centers were used. The trend was calculated by fitting the data to an exponential growth model. RESULTS The incidence of AC of the esophagus in white males is rising in most countries. The highest values of the estimated incidence rate in the year 2000 were found in Great Britain (5.0– 8.7 cases per 100,000 population) and in Australia (4.8 cases per 100,000 population) followed by The Netherlands (4.4 cases per 100,000 population), the United States (3.7 cases per 100,000 population), and Denmark (2.8 cases per 100,000 population). Low rates (< 1.0 cases per 100,000 population) were found in Eastern Europe. The largest changes in incidence were reported in the Southern European countries, with an estimate of the average increase over six registries of 30% per year; in Australia, with an average increase of 23.5% per year; and in the United States, with an average increase of 20.6% per year. The rates of increase ranged from 8.7% to 17.5% on average in Northern Europe, Central Europe, and the United Kingdom. In Eastern Europe, at most, there was a minor rise in incidence. CONCLUSIONS In the Western industrialized nations, the analyzed data show that the incidence of AC of the esophagus has been rising rapidly in the last 20 years. The only exceptions to date are the countries of Eastern Europe. Cancer 2001;92:549–55. © 2001 American Cancer Society.

Histomorphologic regression is an objective response parameter of significant prognostic importance. The diagnostic accuracy of endoscopy, rebiopsy, and EUS is inadequate for objective response evaluation after neoadjuvant chemoradiation and can be omitted for this purpose in the clinical practice.

Our data showed that low intake of vitamin C and E correlates significantly with the development of squamous cell carcinoma as well as adenocarcinoma of the esophagus in males. The relevance of interaction of vitamins with other dietary factors, alcohol, and tobacco are topics of current research.

Introduction: The incidence rates for adenocarcinoma (AC) of the esophagus have risen rapidly in Western nations, whereas the incidence rates for esophageal squamous cell carcinoma (SCC) have remained nearly stable. There are studies about body mass index, smoking, alcohol, and development of AC or SCC. The aim of this study was to evaluate differences in nutritional habits of patients with AC or SCC compared with the population in Cologne. Patients and Methods: From January 1, 1997 to December 31, 1998, 85 patients with esophageal cancer (SCC n = 45, AC n = 40) were interviewed about their nutritional habits using a computerized program (EBIS). By random sample, 100 citizens of Cologne who were similar of age, residence, and nationality were chosen as healthy control group (CG) and were also interviewed with EBIS. Results: The known risk factors, alcohol and tobacco for SCC as well as alcohol and a high body mass index for AC, were confirmed in this study. The CG had a higher daily intake of calcium, magnesium and iron compared to patients with esophageal cancer (p < 0.05). In addition, the tumor group had a significant lower daily supply of carbohydrates, fruits, and dietary fiber (p < 0.001). About 80% of the patients ate more than 100 g meat/day in comparison to 50% of participants in the CG. Patients with AC consumed more magnesium, milk, and animal protein than patients with SCC or the participants of the CG. Conclusion: There are differences in nutrition between healthy controls and patients with esophageal cancer and between patients with SCC and AC. Patients with cancer of the esophagus had a nutritonal deficit in fresh fruit, vegetables, dietary fiber, and carbohydrates. Compared with the other groups, patients with AC had a higher intake of protein, fat, and milk.
