Observation of the curative effect of esophageal cancer with three - dimensional conformal radiotherapy

Abstract

Objective To observe the curative effect of esophageal cancer with three-dimensional conformal radiotherapy and acute adverse reaction. Methods 28 cases with esophageal cancer were received three-dimensional conformal radiotherapy from August,2008 to August,2009. The conformal radiotherapy was performed in the way of 200cGy/fraction,5 fractions/week,total dose of 60-64Gy,30-32fraction. In addition,the curative effect and acute adverse reaction were evaluated along the radiotherapy. Results The number of complete relief(CR) cases was 10, part relief(PR) was 15 ,no change was 3 ,and the overall relief(CR + PR) rate was 89.3%. The local control rate and the survival rate in the first year were 75.0% and 60.7%, and second year were 71.4% and 46.4%. The cases of 0 level acute radioactive pneumonia was 14,1 level was 8,2 level was 5,3 level was 1. The cases of 0 level acute radioactive esophagitis was 5, 1 level was 14,2 level was 7,3 level was 2. Conclusion Three-dimensional conformal radiotherapy was a very safe and effective way to treat esophageal cancer. Whether the therapy could improve the long-term survival rate was remained to be observed. Key words: Esophageal cancer; Radiotherapy,conformal; Surival rate
