Prognosis of early gastric cancer which has malignant disease arising from other organ, especially colorectal cancer, was evaluated. We analysed 747 patients of early gastric cancer surgically treated in the National Kyushu Cancer Center Hospital during the period between 1972 to 1989. Of these cases, multiple cancer was observed in 71 (9.5%), and found in organs next to the colorectun, lung, breast and liver. Early gastric cancer with colorectal cancer was found in 30 cases (42%) (Males numbered 25, and females 5; Synchronous or metachronous cancers numbered 10 and 12). Among these colorectal cancer, the sigmoid colon and rectal cancer were involved in 76.7%. The mean period between early gastric cancer and second colorectal cancer was 4 years and 11 months; that between colorectal cancer and second early gastric cancer was 6 years and 3 months. More than 30% of the death of these multiple cancer was due to colorectal cancer. Overall prognosis of the patients with these multiple cancer was depended on that of colorectal cancer. These data suggested that, in patients with early gastric cancer, it is important to examine the colorectum in 6 to 10 years after gastrectomy.
