 At the National Cancer Center Hospital, in the period from the 1968 to 2002,88 cases of metastatic tumors of the stomach were detected and diagnosed by endoscopic examination and biopsy. In our study, primary cancers were frequently found in lung(22%), breast(20%), malignant melanoma(19%)and esophagus(18%).

 Multiple lesions were seen in only 43% of these cases ; solitary metastases were more common than multiple metastases. Most of the metastatic tumors were located in the middle and upper gastric body, mainly on the greater curvature. Endoscopic appearance was broadly classified into 3 categories, which were(1)submucosal tumor-like formation(50%),(2)cancer-like formation(33%)and(3)others(17%). In category(1),70% of them had a central depression. Concerning category(2),23 out of 29 cases resembled advanced cancer. In conclusion, it is necessary to have a better understanding of the appearance of metastatic tumors of the stomach, so we analyzed their endoscopic features. Endoscopic examination is helpful both for detecting tumors and for indicating their proper treatment.
