 Six cases of stomach GIST with lymph node metastasis were studied, The frequency of lymph node metastasis was 5.8% (6/103) totally and 8.7% (6/69) in high grade GIST. The diameter of the GISTs with lymph node metastasis was more than 5 cm. Two styles of metastasis could be observed, one was true and the other was through vessel involvement. One of our patients with true lymph node metastasis survived for more than 5 years. In stomach GIST, lymph dissection following stomach cancer is unnecessary, but it is desirable to perform an operation for resection of the area neighboring the site of the resected GIST, when the tumor exceeds 5 cms in size. There are a few cases of lymph node metastasis now, and the benefit of lymph node dissection as a future precaution meeds further study.
