Trends in incidence of esophageal and gastric cardia cancer in high-risk areas in China.

Incidence rates have risen for gastric cardia adenocarcinoma, whereas rates have remained stable for esophageal squamous cell carcinoma in many western countries. The aim of this study was to describe and analyze trends in incidence rates for esophageal cancer and gastric cardia cancer in Cixian county, which is one of the high-risk areas for esophageal cancer in China as well as in the world. The data were obtained from the Cixian Cancer Registry, which is a population-based registry.

[Study on the esophageal cancer incidence and mortality rate from 1974-2002 in Cixian, China].
