宫颈癌治疗方法早期以根治性手术为主,晚期则以放射性治疗为主,因为宫颈、阴道为天然腔道且对放射线耐受量高,非常适合作腔内后装治疗,因此,腔内后装配合体外照射被认为是宫颈癌放疗的经典模式[1];然而,其较重的近、远期放射性不良反应限制了临床疗效的发挥。调强放疗[2](IMRT)是近年来开展的放疗新技术,理论上具有更高 Early treatment of cervical cancer mainly radical surgery, late radiotherapy is the main, because the cervix and vagina for the natural cavity and high tolerance to radiation, is very suitable for intracavitary after-treatment, therefore, intracavitary Combined with external beam irradiation is considered to be a classic model of cervical cancer radiotherapy [1]; however, its serious short-term, long-term adverse effects of radioactive limited clinical efficacy. IMRT [2] (IMRT) is a new radiotherapy technology developed in recent years, in theory, has a higher
