Objective:To study the effect of line accelerator radiotherapy for advanced esophageal carcinoma.Methods:Data were collected from 80 patients with advanced esophageal cancer admitted to our hospital from January 2011 to January 2018,the double-blind method was divided into two groups:the control group(n=40)treated with cobalt-60 radiotherapy and the scientific research group(n=40)treated with linear accelerator radiotherapy.Results:There was no difference in tumor markers,immune function and quality of life before treatment,and no difference in adverse reactions after treatment(P>0.05),in the observation group,SCC-Ag,CEA,CYFRA21-1,CA19-9 were lower,CD3+,CD4+,and CD4+/CD8+were higher,CD8+was lower,QLQ-C30 was higher,and the effective rate in the observation group(97.50%)was higher than that in the control group(85.00%),P<0.05.Conclusion:CT-guided linear accelerator radiotherapy for advanced esophageal carcinoma can decrease the level of tumor markers,improve the immunity and quality of life,enhance the curative effect and reduce the side effects.
