Between 1965 and 1983 we treated 129 patients with primary esophageal squamous cell carcinoma. Of these patients, 12 (9.3%) had previously undergone partial gastrectomy and six manifested tumors in the lower thoracic esophagus. Esophagitis of the noncancerous esophageal mucosa surrounding the cancer was confirmed in three of five patients who underwent esophagectomy. We also retrospectively evaluated 130 patients with esophageal cancer who had undergone gastrectomy, including our 12 patients, reported in the Japanese literature between the same period. Between patients with esophageal cancer who had undergone gastrectomy and those who had not there was no age difference; there were more men in the first group. Cancer developed in the lower thoracic esophagus with relatively high frequency in patients who had undergone gastrectomy compared with those who had not. The possibility of an association between gastrectomy and the subsequent development of esophageal cancer, especially lower thoracic esophageal cancer, cannot be ruled out. Further studies are necessary to clarify a possible association.
1965年至1983年间，我们治疗了129例原发性食管鳞状细胞癌患者。在这些患者中，12例（9.3%）曾接受过部分胃切除术，6例表现为胸段下段食管癌。在接受食管切除术的5例患者中，有3例证实癌旁非癌性食管黏膜存在食管炎。我们还回顾性评估了130例接受过胃切除术的食管癌患者，包括同期日本文献报道的我们的12例患者。接受胃切除术的食管癌患者与未接受胃切除术的患者之间不存在年龄差异；第一组男性更多。与未接受胃切除术的患者相比，接受胃切除术的患者胸段下段食管癌的发生频率相对较高。不能排除胃切除术与随后食管癌尤其是胸段下段食管癌发生之间存在关联的可能性。需要进一步研究以阐明可能的关联。
