Abstract:
Objective This paper investigated the clinical application of CRT+ARC technique in locally advanced lung cancer. Methods A total of 100 patients with locally advanced lung cancer who underwent radiotherapy in our hospital from March 1,2016 to March 1,2017 were randomly assigned to the experimental and control groups. Each group consisted of 50 patients. The CRT+ARC plans were made for the experimental group,and the CRT + intensity-modulated radiotherapy(IMRT)(CRT+IMRT) plans for the control group. According to the World Health Organization( WHO) criteria,the short-term efficacy of patients was as-sessed. According to the imaging examination and the Radiation Therapy Organization Group(RTOG)standard,the occurrence of major side effects of radiation pneumonia was identified. Results The effective rate of treatment was 82% in the experimental group and 76% in the control group. There was no difference in the effective rate between the two groups(χ2 =0. 542,P=0. 461). The incidence of pneumonia in the experimental group was 22% ,and 18% in the control group. There was also no difference in the incidence of pneumonia between the two groups(χ2 =0. 250,P=0. 617). Conclusion In the clinical application of locally advanced lung cancer, CRT+ARC technique has no difference in the short-term efficacy and the main side effects of radiation pneumonitis compared with CRT+IMRT.
