During the past 10 years, postoperative mortality associated with surgical treatment of oesophageal carcinoma has been reduced by one-half. However, it appears that all efforts to improve long-term survival with extensive excisional procedures and adjuvant chemotherapy and radiotherapy have failed. Fifty-six of 100 patients presenting to the surgeon with an oesophageal carcinoma have resectable disease. Recent studies suggest that seven of them will die from postoperative complications and 49 patients will be discharged from the hospital after an average of 3 weeks. Of these patients, 27 will survive the first, 12 the second, and ten the fifth year. Although it may be possible to further reduce postoperative complications and mortality, the chances of improving the long-term prognosis of patients with oesophageal carcinoma seem small.

The now-matured study shows that 17-1A antibody administered after surgery prevents the development of distant metastasis in approximately one third of patients. The therapeutic effect is maintained after 7 years of follow-up evaluation.

Postoperative radiation therapy following curative resection of squamous cell carcinoma of the esophagus was investigated in a prospective randomized study. A group of 33 patients received postoperative radiation therapy and were compared to a control group of 35 patients treated by surgery alone. No statistically significant differences were noted between the two treatment groups concerning overall and disease-free survival rates. Postoperative irradiation significantly increased the incidence of fibrotic strictures of the esophagogastric or esophagocolonic anastomoses and caused a delayed recovery of patients quality of life. Based on these results, we believe that postoperative radiation therapy alone cannot be advocated as a adjuvant therapy following curative resection of squamous cell carcinoma of the esophagus.

Quality of life (QL) after the "curative" resection of non-small cell bronchogenic carcinoma was assessed by patients using the EORTC QL questionnaire (QLQ) and by a psychologist using the Spitzer Index. Quality of life was assessed in 52 patients on one occasion 12 months postoperatively and in 20 patients regularly starting with a preoperative assessment. Self- and external evaluation showed a significant correlation (r = 0.41), but QL was assessed as being higher by the external observer. After surgery it was mainly affected by restrictions related to physical activities, job and household tasks, and disease symptoms, whereas limitations in emotional, social, and financial domains were found less frequently and less severely. Of the different medical (surgical procedures, tumor recurrence) and social factors (sex, marital and employment status), only tumor recurrence was determined to have a significant and negative influence on postoperative QL (P < 0.02). When compared to the preoperative assessment, QL had deteriorated on discharge from hospital but was restored within 3-6 months postoperatively in disease-free patients.

In a prospective randomized study, one- and two-layer anastomoses were compared following subtotal oesophagectomy and gastric substitution with cervical oesophagogastric anastomosis. After 54 one- and 53 two-layer procedures the rates of anastomotic leakage were the same (19 per cent). After a mean follow-up of 44 weeks, 13 of 51 patients (25 per cent) undergoing one-layer anastomosis and 28 of 50 (56 per cent) having the two-layer procedure complained of cervical dysphagia and required dilatation. The anastomotic strictures were fibrotic in 11 of 51 patients (22 per cent) undergoing one-layer anastomosis and in 24 of 50 (48 per cent) receiving the two-layer operation. Strictures were malignant in two and four patients (4 and 8 per cent) respectively. The lower incidence of fibrotic stricture following one-layer anastomosis was significant (P < 0.01), but not that of malignant stricture. With comparable leakage rates, one-layer anastomosis is superior to the two-layer procedure because of the lower incidence of fibrotic stricture.
