It is the most serious and most urgent complication of esophageal cancer. Once it happens, it is difficult to rescue and the mortality rate is high. It can occur before, during, and after radiotherapy for esophageal cancer. From 1986 to 1998, 386 cases of esophageal cancer patients were treated in our department.
