Trends of cancer incidences on the distal esophagus and gastric cardia in Jeju residents，

Abstract

Objectives: The aim of this study is to evaluate trends in incidence rates for distal esophageal cancer and gastric cardia cancer according to subsite over the period 2000-2003 in Jeju and to review the effects of reclassifying two regions by tumor location.Methods: The subjects were obtained from the database of Jejudo Cancer Registry (JCR). AII patients were diagnosed newly as esophageal and gastric cancers from 2000 through 2003. Crude incidence rates (CR) and age-standardized incidence rates (ASR) were computed by anatomic subsites and sex. Results: Between the years 2000 and 2003 there were 86 cases of esophageal cancer in Jeiu. In 2000-2001, the ASR of distal esophageal cancer in men was 0.84/100,000: it declined to 0.27/100,000 in 2002-2003. The ASR of distal esophageal cancer in women was 0 from 2000 to 2003. For gastric cancer, there were 876 cases between the years 2000 and 2003. In 2000-2001, the ASR of gastric cardia cancer in men was 0.74/100,000; it increased to 1.62/100,000 in 2002-2003. The ASR of gastric cardia cancer in women was 1.01/100, 000 in 2000-2001; it declined to 0. 52/100,000 in 2002-2003.Conclusions: There was no evidence about increasing incidence of distal esophageal cancer in both men and women. But an increasing trend of esophageal cancer in both men and women and an increasing trend of cardia cancer in men and an deceasing trend of non cardia cancer in men were observed, as like as western countries.
