ABSTRACT
Objective To investigate the relation of pelvic three-dimensional conformal radiotherapy(3D-CRT) target with rectal dose distribution and irradiation volume in cervical cancer.Methods In 45 patients with cervical cancer(Ⅱa-Ⅲb) treated in our department from September to December 2006,we compared rectal dose distribution in different treatment plans conventional radiation,4-field box radiation,4-field oblique radiation and 5-field radiation,and studied the relationship between rectal irradiation volume and dose in the target area.Results Compared with that of the other models,the dose distribution of CTV in 3D-CRT was relatively poor although it could satisfy the demand of treatment;dose distribution of D90,D80 and D50 in the radiated rectum differed significantly(P
