    Abstract:
    In this paper we report on the long-term results achieved in 75 patients with superficial carcinoma of the thoracic esophagus who have been treated since 1965 with esophagectomy at our institute. In three of these patients, the carcinoma was limited to the epithelium (intra-epithelial carcinoma), while in 13 cases it was confined to the mucosa, and in 59 cases to the submucosa. There was no lymph node metastasis in patients with intra-epithelial or mucosal carcinoma, but lymph node involvement was found in 13 (22.0%) of the 59 cases of submucosal carcinoma. The five-year survival rate of patients with intra-epithelial carcinoma and mucosal carcinoma was 100%, which was significantly better than that for carcinoma invading the submucosa (49%). The five-year survival rate for patients with lymph node involvement was only 46%, which was significantly worse than that for patients without lymph node involvement (60%). No recurrence occurred in patients with intra-epithelial carcinoma or mucosal carcinoma, while recurrent disease occurred in 19 (32.2%) of the 59 patients with submucosal carcinoma. Lymph node recurrence and hematogenic recurrence such as lung and bone metastasis were the most frequent developments in patients with submucosal carcinoma of the esophagus.
