Study of 3 dimensional conformal radiation therapy for local recurrence after radical radiotherapy of esophageal carcinoma

Objective To evaluate the effect of 3 dimensional conformal radiation therapy for recurrence esophageal carcinoma after radical radiotherapy.Methods 60 esophageal carcinoma patients with local recurrence after their initial radiotherapy received retreatment with stereotactic radiotherapy.The acuate side effect,survival rates and immediate response were evaluated.Results All 60 patients completed there seconed course radiotherapy.The overall response rate was 78.2% with CR in 35 patients(58.3%),PR in 12 patients(20%),SD in 8 patients(13.3%) and PD in 5 patients(8.3%).The survival rate of patients within 6 months was 65%(39/60),and for 1,2 and 3 year were 31(51.6%),33.3%(20/60),16.7%(10/60),respectively.Conclusion 3 dimensional conformal radiation therapy is an alternative effective method for the in-patients with recurrence esophageal carcinoma after radical radiotherapy.
