Objective To evaluate the long term curative effects of radiotherapy combined with photodynamic therapy on the advanced esophageal cancer.Methods From Oct 1991 to Dec 1992, 60 patients with advanced esophageal cancer were randomly divided into two groups, 30 patients received conventional radiotherapy alone (CRT), the other 30 cases received radiotherapy combined with photodynamic therapy (PRT). After PRT the total dose of 40Gy,for 4 weeks the hematoporphyrin derivate(HpD) was given using 5mg/kg body intravenously and after 48 and 72 hours,the location of lesion were irradiation by 630-nm red light with 400～500mW/cm 2. Laser irradiation was given for 15 minutes to each part of tumor.Results The 5,10-year survival rates were 16 7% ,10 0% respetively;for CRT group and 29 9%, 16 7% respectively; for PRT group, The difference was significant (P
