ABSTRACT
Objective To explore the clinical effect of new type rectal cancer radiotherapy individualized fixation device in the radiotherapy of rectal cancer. Methods From June 2015 to December 2016,60 patients with rectal cancer who accepted the external irradiation in Zhejiang Tumor Hospital were divided into two groups by random number table method. A group(31 cases) received new type rectal cancer radiotherapy position fixation devices with thermoplastic film. B group(29 cases) received simple foam pad with thermoplastic film. Before each treatment,Cone beam CT(CBCT) scan was conducted. The applied CBCT image and the planned reconstruction image were compared in the direction of X(left and right),Y(upper and lower)and Z(front and rear) axis. The setup error was recorded, and the correlation between the two groups was analyzed. Results The average setup error of patients in A group in X (left and right),Y(upper and lower),Z(front and rear) axis were (1. 61 ± 0. 18)mm,(1. 82 ± 0. 13)mm,(1. 91 ± 0. 11)mm,respectively. The average setup error of patients in B group in X(left and right),Y(upper and lower),Z (front and rear) axis were (2. 22 ± 0. 13)mm,(2. 43 ± 0. 14)mm,(2. 36 ± 0. 13)mm,respectively. There were statistically significant differences between the two groups(t=14. 958,17. 501,11. 283,all P<0. 001). Conclusion The new type of rectal cancer radiotherapy position fixing device is more comfortable than the simple foam pad,and the setting error is smaller than the simple foam pad.
