ABSTRACT

Double primary cancer means that more than 2 cancers occur independently in an individual. There have been many reports on double primary cancer since Billroth reported it for the first time in 1889 and Warren and Gates established it. The incidence of esophageal cancer is low, about 1~2% of all cancer and, 7% of all gastrointestinal cancer, but double cancer with including esophageal cancer is 9.5~27% of all double primary cancer. Double primary cancer of the esophagus and stomach has occasionally been reported. We have experienced three cases of double primary cancer of squamous carcinoma in the esophagus and adenocarcinoma in the stomach. In this study we reviewed the clinical characteristics of the reported cases of double primary esophageal and gastric cancer that have been reported in Korea and these three cases we experienced at our hospital.
