右側結腸癌に対するリンパ節郭清範囲の検討

The lymph node metastases of the right side colon were studied. Among 58 cases of right side colon, nodal involvements were found in 53.4%. Metastases to the epicolic and paracolic nodes were confined to an area within 10 cm from the tumor margin. Metastases to the intermediate nodes were found in 20.7% and metastases to the main nodes in 15.5%. Jumping metastases were recognized in 5 out of 31 cases of nodal involvement (16.1%). As the rate of jumping metastases is unexpectedly high, lymph node dissection for right colon cancer should be done as far as the main nodes.
