21 cases of carcinoma of esophagus, which were treated by us for the past 7 years, were reviewed.
15 cases of these were treated with CO60 irradiation, 7 of which were treated further with surgical operation after 3-4 weeks.
Repeated cytological examinations were done during the irradiation, and it was recognized that the effect of the irradiation became apparent when 1, 000r. or more was given. Also recognized was that the preoperative irradiation was useful.
