During a 2 1/2-year period, 60 consecutive patients with cancer of the
thoracic esophagus were randomized to undergo a cervical or thoracic
anastomosis. The tumors were staged postoperatively (stage I, n = 2; stage
II, n = 19; stage III, n = 9; and stage IV, n = 30) and were almost equally
distributed between the two groups. The upper limit of three tumors was
above the convexity of the aortic arch. The esophageal specimens were
studied with regard to measurements of the tumor and of the resected
esophagus. The microscopic aspects were evaluated by serial sections after
vital staining. The prevalence of ignored plurifocal cancers, of submucosal
infiltrations, and of distant areas of dysplasia in both groups was
confirmed. Malignant invasions of esophageal sections were more frequent in
patients undergoing thoracic anastomosis (10 versus 3), and diseased upper
mediastinal lymph nodes were more frequent in those undergoing cervical
anastomosis (17 versus 7). Mortality was equally divided between the two
groups. Respiratory complications and recurrent laryngeal trauma were more
frequent in patients having cervical anastomosis. Long-term survivors had
stage N0 disease, with a healthy esophageal section. Even though subtotal
esophagectomy reduces the prevalence of microscopic esophageal wall
invasion above the tumor and allows more complete unilateral exploration
and resection of invaded lymph nodes, it offers no significant benefit
concerning survival of patients with advanced cancer and malignant
lymphadenopathy.
