Results of surgical treatment of epidermoid carcinoma of the thoracic esophagus

: During 1979 to 1991, 125 patients with epidermoid carcinoma of the thoracic esophagus were admitted to our General Surgery unit. The average age was 60.1 years; 94.4 percent of the patients were male. The mean duration of symptoms was 3.65 months. The most frequent symptom was dysphagia in 97.19 percent, followed by weight loss in 64.48 percent. The most frequent location was the middle one-third in 58.4 percent. The tumor was well differentiated in 27.2 percent, moderately well differentiated in 41.6 percent and poorly differentiated in 31.2 percent. By preoperative staging, 1 patient was stage I, 24 were stage II, 86 were stage III and 14 were stage IV. The operability rate was 76 percent and the resectability rate was 48.8 percent. Resection was "curative" in 42.62 percent and palliative in 57.37 percent. Radiation therapy and chemotherapy were used only in those patients who did not undergo resection. All of the patients in whom resection was possible underwent a single-stage esophagogastrectomy. The postoperative mortality rate was 20 percent, but only 11.54 percent if we only consider those patients who underwent "curative" resection. The most frequent causes of mortality were respiratory complications and anastomotic leakage. The five year overall survival rate was 5.99 percent. In the resected group, the five year survival rate was 8.82 percent and in patients in whom resection was considered "curative," the rate was 20.86 percent.
