title: [Distribution of recurrent lesions after radical resection of cancer of the thoracic esophagus].
abstract: In 150 patients who got cancer recurrence after curative resection for cancer of the thoracic esophagus, the sites where recurrent lesions were clinically detected for the first time were examined. The distribution of recurrent lesions in patients who did not undergo neck dissection at the operation (group A) differed from the distribution in those who underwent neck dissection (group B). Cervical and/or upper mediastinal recurrence occurred in 49% of cases in group A and in 11% of group B. On the contrary, middle or lower mediastinal recurrence was more often in group B. The distribution of recurrent lesions varied depending on the state of lymph node metastasis detected at surgery. Cervical and upper mediastinal recurrence was much more frequent than hematogenic recurrence in cases without lymph node involvement in group A, while hematogenic recurrence was more frequent in cases with both mediastinal and abdominal lymph node metastasis. In the upper mediastinum, recurrence along the recurrent laryngeal nerves was most frequent and it was supposed to have developed from residual lymphatic metastases. In the middle and lower mediastinum, recurrent lesions were located around the left main bronchus and descending aorta, and cancer infiltration of the neighboring organs was frequent. Recurrence at the abdominal paraaortic nodes was observed mainly in cases with perigastric lymph node involvement.
