[Clinicopathological studies of the recurrence of esophageal squamous cell cancer--with special reference to the mode of recurrence and operative procedure].
In 93 out of 201 patients (46%) with squamous cell carcinoma of the esophagus who underwent radical resection (excluding death within 30 days after operation), the site of recurrence could be identified by means of X-ray, CT, ultrasonography, and biopsy. Recurrence was found in 55% of 93 cases within 12 months after surgery and in 86% of 93 cases within 24 months. Of 93 patients with recurrences, lymph node recurrences were present in 44 cases, visceral recurrences in 32 cases, both lymph node and visceral recurrences in 11 cases and others in 6 cases. Neck and/or upper mediastinal lymph node recurrences were found in 10 out of 15 patients who had recurrences within 3 months after surgery. Careful examination should be made in the left recurrent nerve chain and extended lymph node resection of upper mediastinal region should be performed under the adequate indication. Esophageal squamous cell cancer has a tendency to recur in the lymph nodes initially, and visceral metastases may occur thereafter. The incidence of visceral recurrence increased remarkably, when neck and/or upper mediastinal lymph nodes were involved at the time of operation. Accordingly, both irradiation and chemotherapy should also be applied for improving the prognosis of esophageal carcinoma.
