Abstract
Although locoregional recurrence is often observed in the cervicothoracic area even after an esophagectomy with three-field lymph node dissection (3FL), recurrence in the mediastinal lymph nodes is relatively rare. We experienced two cases of solitary recurrence in a posterior mediastinal node (No 112-ao) after a curative resection for thoracic esophageal cancer. The lymph node recurrence was located in the connective tissue adjacent to the left posterior wall of the thoracic aorta, and thus could not have been removed by the conventional approach of an esophagectomy through a right thoracotomy. These two patients underwent surgical removal of the tumor through left thoracotomy, and survived for 5 years and 1 year without recurrence, respectively. Because the rate of metastasis in this area appears to be low, it is not always necessary to perform complete nodal dissection of the left side of the descending aorta at the initial surgery in cases of thoracic esophageal cancer. However, our experience suggests the importance of periodic computed tomography scans to check for any nodal recurrence in this area, since a surgical resection may be effective when the recurrence is detected as a solitary metastasis.
