Abstract: Radiotherapy has become one of the most important treatments for cervical carcinoma. In recent years, because of the organ motion, anatomical changes and setup errors et cetera, the accurate external beam radiotherapy (EBRT) may regard to the difference between the actual dose delivery and the pretreatment plan, which not only causes target less, but also brings additional doses to the organs at risk (OAR). By using of image guidance and individual modelling, adaptive radiotherapy (ART) can analyze the parameters of target position, volume and dose and adjust optimized plans for the followup treatment based on aforesaid feedbacks and enable the enhancement of the local control rate while reducing the incidence of the side reaction.

Key words: Uterine cervical neoplasms, Radiotherapy, intensitymodulated
