title: Clinical evaluation of radiotherapy for advanced esophageal cancer after metallic stent placement.
abstract: OBJECTIVE
  To evaluate the therapeutic effect of radiotherapy for esophageal cancer after expandable metallic stent placement.
  
  
  METHODS
  Ten cases of advanced esophageal cancer were evaluated, 7 having complete obstruction and 3 with digestive-respiratory fistula. Ten nitinol stents were placed at the site of stenosis. Patients were treated with a total dose of 1 200 cGy divided into 3 fractions of 400 cGy 4-7 d after stents placement.
  
  
  RESULTS
  All the 10 stents were placed successfully at one time. After radiotherapy for advanced esophageal cancer, the survival period of the cases ranged from 14 to 22 mo, with a mean survival of 17 mo. No re-stenosis occurred among all the 10 cases.
  
  
  CONCLUSIONS
  Stent placement combined with radiotherapy for esophageal cancer is helpful to prolong patients' survival and reduce occurrence of re-stenosis.
