Abstract: Objective To explore treatment effect of recurrent nasopharyngeal carcinoma ( NPC) with threedimensional conformal radiotherapy (3DCRT). Methods 43 cases were selected to treat with 3DCRT. The radiation method was 5 times each week,2Gy one time,one time each day,the total doses was(60-70)Gy/(30-35) times. The treatment effect of patients in the near future ,2 years survival rate and radiation complication were observed. Results One month after 3DCRT, then re-check, the results showed that complete relief rate was 58.1% (25/43) , partial relief rate was 30.2% (13/43) ,the total relief rate was 88.4% ,and 2 years survival rate was 69. 8% ,the local control rate in target area was 92.2%. But 2 cases were deaf, 1 case had oral inflammation. Conclusion With 3DCRT, recurrent NPC patients had well near future treatment effect and survival rate,furthermore,the radiation injury was rather low.
