THE CLINICAL APPLICATION OF VMAT IN LOCALLY ADVANCED CERVICAL CANCER
Objective To observe the application effect of VMAT in locally advanced cervical cancer.Methods The clinical data of 135 patients with locally advanced cervical cancer were retrospectively collect-ed and divided into two groups according to different treatment methods:70 VMAT cases and 65 IMRT cases.The target volume dose was planned to be 50.4Gy,and the target parameters,organ dose at risk,treatment time,short-term efficacy,acute adverse reactions and Overall Survival(OS)were compared be-tween the two groups.Results CI value in VMAT group was higher than that in IMRT group(t=2.04,P=0.04),and treatment time was shorter than that in IMRT group(t=30.57,P<0.001).There was no statistical significance in other indexes between the two groups(P>0.05).Conclusion Compared with IMRT,VMAT has better conformation and can clearly shorten the treatment time of locally advanced cer-vical cancer patients.
