From March, 1983 to March, 1987, 16 patients with esophageal steno-obstruction due to nonesophageal tumors were treated in the Division of Therapeutic Radiology, Kangnam St. Mary´s Hospital, Catholic University Medical College. The patient characteristics, effect of radiotherapy (XRT) on esophageal steno-obstruction and survival were evaluated. The most common primary tumor was lung cancer (14/16) and the middle third of the esophagus was most frequently involved (14/16). Improved clinical response was observed in 80% of the patients who finished the planned courses of XRT. The mean radiation dose evoking the improvement of dysphagia was 2,993 cGy given over a period of 3 to 4 weeks. The Kaplan-Meier estimates of survival at 15 and 30 weeks of follow-up were 60% and 46%, respectively. In the completed group who finished the whole planned courses of XRT, survival rates were 77% and 51%, respectively. Four patients were alive over 90 weeks with normal passage of food.
