ABSTRACT
Objective:
To investigate the application effect of intensity-modulated radiotherapy guided by computed tomography/magnetic resonance imaging (CT/MRI) fusion technology in patients with nasopharyngeal carcinoma.Methods:
The case data of 112 patients with nasopharyngeal carcinoma in 904 Hospital from June 2013 to January 2018 were retrospectively analyzed. They were divided into control group (three-dimensional conformal radiotherapy guided by CT/MRI image fusion technology) and observation group (intensity-modulated radiotherapy guided by CT/MRI image fusion technology), with 56 cases in each group. The average target volume, short-term efficacy, incidence of toxic and side effects of radiotherapy, 1, 2 and 3-year survival rate and recurrence rate were compared between the two groups.Results:
The target volume in the observation group was larger than that in the control group ( P<0.05), and the total effective rate (78.57%) was higher than that in the control group (60.71%, P<0.05); There was no significant difference in the incidence of dry mouth, temporomandibular joint injury, hearing loss and skin injury between the two groups ( P>0.05), but there was significant difference in the total incidence of toxic and side effects ( P<0.05); There was no significant difference in 1-year and 2-year survival rate and recurrence rate between the two groups ( P>0.05); The 3-year survival rate (82.14%) in the observation group was higher than that in the control group (64.29%), and the recurrence rate (8.93%) was lower than that in the control group (23.21%, P<0.05).Conclusions:
CT/MRI image fusion technology can guide the intensity-modulated radiotherapy in patients with nasopharyngeal carcinoma, which can improve the accuracy of radiotherapy target volume delineation and the total effective rate of treatment and 3-year survival rate, and reduce the 3-year recurrence rate. It is worthy of clinical promotion and application.
