ABSTRACT
Objective To assess and compare the advantages and disadvantages of five fields of three dimensional conformal radiation therapy(3DCRT),three fields of 3DCRT and the simulator-guided radiation therapy for patients with esophageal carcinoma.Methods Twenty patients with esophageal carcinoma were treated by three dimensional conformal radiation therapy,at the same TPS,three Dimensional conformal radiation therapy target and normal tissue of three radiotherapies were simulated.The treatment planning was five days per week with 1.8~2.0 Gy per fraction。 5 fractions per week,5OGy per 5~6 weeks. Results Compared with simulator-guided radiation therapy,3DCRT planning has better dose distribution and protection of normal tissue. Conclusion Esophageal cancer conformal radiotherapy can reduce the radiation injury of the normal tissue and complications,and improve treatment of conformal radiotherapy and the target dose distribution.
