The priamry sites of cancer were stomach in 12 cases, colon in 2 cases, and esophagus, larynx, ovary and uterus each in one case. As to histological type, 3 cases were squamous cell carcinoma. On the other hand, remaining 15 cases were adenocarcinoma. The period between surgical resection of primary tumor and detection of metastasis ranged from 1 year to 8 years and 10 months. Most of the cases showed symptoms due to stenosis and only 2 cases presented bloody stool. Motastatic colon cancer was histologically confirmed in olly 2 cases. Resection of the metastatic lesions was performed in 9 cases. The prognosis was extremely poor, the 5-year survival rate for the whole 18 cases being only. 6 %. However, 3 out of 9 cases in which the metastatic lesions were resected survived for 2 years and more. Therefore, it is considered important to identify metastatic lesions at early stage and resect them as completely as possible.
