Sixty patients with thoracic esophageal carcinoma were studied regarding the metastatic spreading state of lymph node. In the patients with carcinoma of Iu location, all of the positive lymph nodes were situated in two regions as cervico-thoracic or thoraco-abdominal one. Involved lymph nodes were found in the neck and the upper abdominal region in 57.1 per cent and 42.9 per cent of the patients respectively. In patients with carcinoma of Im location, the metastatic rates of n_2 and n_3 were 35.6 and 31.1 per cent respectively. It means that thoracic esophageal carcinoma spreads easily into the wide range of thoracic and abdominal lymph nodes. Recently, it is recommended that lymph nodes in the upper mediastinum should be resected extensively and meticulously so that the patients may be free from cancer recurrence. Considering the increasing of number and the widening of resected area of the nodes around the trachea, it is necessary for a group of nodes of #106 to be classified more subdividedly from the surgical point of view. The rates of the abdominal and the supraclavicular nodal involvement were 37.5 and 12.5 per cent respectively even in Ei carcinoma. Therefore, supraclavicular lymph nodes should be routinely inspected and upper abdominal nodes are regarded as the primary lymphatic drainage. In the patients with nodal involvement more than n_2,the rate of microscopic cancer invasion into the lymph vessels was significantly high.
