Zusammenfassung:The effect of gastrectomy on the subsequent development of esophageal cancer was investigated, focusing on its multicentric occurrence. We retrospectively evaluated 28 patients who underwent subtotal esophagectomy for intrathoracic esophageal cancer between 1985 and 1999. They were divided into two groups according to whether or not they had previously undergone a gastrectomy: group 1, comprising 7 patients who had undergone gastrectomy and group 2, comprising 21 patients who had not. Clinical profiles of the patients were obtained from the medical records and the whole resected esophagus was histopathologically examined. The interval between gastrectomy and esophagectomy in group 1 was significantly shorter in the patients who had undergone gastrectomy for gastric cancer than in those who had undergone gastrectomy for a peptic ulcer, and also in the patients for whom anastomosis had been performed by Billroth I compared with Billroth II. The patients in group 1 were significantly younger than those in group 2. The multiple occurrence of esophageal cancer was found in 4 of 5 patients (80%) in group 1, and in 2 of 18 patients (11%) in group 2, with significantly higher frequency being seen in group 1. More than two coexisting cancer lesions apart from the primary tumor were detected in all four patients. Histological examination of all the coexisting cancer lesions showed well-differentiated squamous cell carcinoma confined within the superficial mucosal layer. No significant differences were noted in the location of the coexisting lesions between the oral and anal side of the primary tumors. Squamous dysplasia was randomly observed, especially around the cancer lesions. These findings suggest that gastrectomy precipitated subsequent chronic gastroesophageal reflux which in turn induced the development of squamous dysplasia and carcinoma at multiple locations in the esophagus.
