Objective To analyze the efficacy of radiotherapy in cervical and upper thoracic esophageal cancer and cervical supraclavicular region. Methods Sixty patients with cervical and upper thoracic esophageal cancer were treated with radiotherapy in the neck and the supraclavicular region. DT 45 to 50 Gy/4.4 to 6 weeks were compared with patients in the same period. Results The lymph node metastasis rate in prevention group was 1 7%, which was significantly lower than that of control group 18 3%, P <0 01. The survival rates of the two groups were compared, and the 2-year survival rate prevention group was significantly improved. Conclusion The prevention of radiotherapy in cervical and upper thoracic esophageal carcinomas in the neck and double supraclavicular region has a positive effect.
