Abstract

Lymph node metastasis is a risk factor for the occurrence of peritoneal dissemination and liver metastasis in patients with gastric cancer. We analysed data on 893 Japanese patients with serosally invasive gastric cancer, with respect to the relation between lymph node metastasis and peritoneal dissemination or liver metastasis. All these patients were treated in our clinics. Lymph node metastasis was evident in 746 patients, and in these patients the tumors were larger, lymphatic and vascular involvement were prominent and rates of peritoneal dissemination and liver metastasis were higher. In 147 patients with no evidence of lymph node metastasis, peritoneal dissemination was seen in 3.4% of cases and there was no liver metastasis. In cases of peritoneal dissemination and in those with liver metastasis, the rate of lymphatic involvement was higher than when there was vascular involvement. Peritoneal dissemination and liver metastasis are likely to be concomitant with lymph node metastasis in cases of serosally invasive gastric cancer. It seems apparent that lymphatic spread leads to peritoneal dissemination and liver metastasis in patients with gastric cancer.
