Clinicopathologic study of esophageal cancer associated with simultaneous metastatic lesions in the stomach.

Between 1965 and 1985, 89 Japanese patients with esophageal squamous cell carcinoma underwent esophagectomy. In five of them (5.6%), a simultaneous metastatic lesion from the esophageal cancer was detected within the stomach in the resected specimens. Preoperative diagnosis of the gastric lesions had been made in none of the five patients because of an obstruction that was due to esophageal cancer. All gastric lesions were located at the gastric cardia, close to the esophagocardial junction, with a mean distance of 6.9 +/- 2.0 cm from the primary esophageal lesions. Provision of a gastric tube that contains metastatic lesions, for reconstruction of a new alimentary tract after esophagectomy, must be avoided. In cases of inadequate preoperative gastric examination, gastric lesions should be searched for intraoperatively, not only by serosal inspection and palpation, but also by mucosal inspection and palpation after partial proximal gastrectomy.
