[Abstract]:Objective to evaluate the mobility of conformal intensity modulated radiotherapy (IMRT) (CTV) in patients with unoperated cervical cancer by conical beam CT (CBCT) (TBI), and to provide a reference for the setting of CTV-ITV extension value (IM) in patients with non-surgical radical radiotherapy for cervical cancer. Methods from December 2013 to October 2014, 20 patients with unoperated cervical cancer receiving radical IMRT were collected, and the displacement and deformation of tumor clinical target on CBCT and localization CT images were compared. Results the tumor clinical target area (CTV1-CBCT) was (33.56 鹵22.52) cm~3 (range: 1.04 鹵110.22 cm~3) on CBCT images of 20 patients with cervical cancer, and the percentage of CTV1 1-CBCT relative to CTV1 was (10.19 鹵6.32)% (range: 0.37 鹵32.01%). CTV1 was found in the uterine body and para-uterine body, after the uterine body and para-uterine body, before the cervix, after the cervix, on the upper uterine body, on the side of the uterine body, during the 140th CBCT scan. The maximum deformation length of the opposite side of uterine body was (1.19 鹵0.82) cm, () 0.80 鹵0.55) cm, (0.16 鹵0.25) cm, (0.23 鹵0.29) cm, (0.27 鹵0.42) cm, (0.18 鹵0.24 cm and (0.78 鹵1.09) cm.2 cm, respectively. There were individual differences in the motility of the clinical target area among the patients. Conclusion using CBCT to obtain three dimensional IM with different direction and different size IM in cervix and uterine body, and combining with individual image guided radiotherapy strategy may be a better clinical form of accurate radiotherapy for cervical cancer at present.
