Abstract
We experienced a case of coexistence of GIST and gastric and colon cancer. An 87-year-old man was diagnosed as having early gastric cancer in other hospital. Through the preoperative examinations in our hospital, a small intestinal tumor and colon tumor were discovered. After conservative therapy to DIC, only partial resection of jejunum and ileocecal resection were done without gastric resection to minimize the surgical stress. We planned to do gastric surgery later. The histrogical diagnosis of jejunal tumor was GIST on the basis of c-kit (+), CD34 (+) in immunofluorescent stain.
The coexistence of GIST and other tumor is rare, only fourteen cases having been previously reported in Japan. We believe that the coexistence of GIST and other tumor has good prognosis after radical resection.
