While there has been recent improvements in the treatment of more advanced stages of cervix cancer by combining radical radiation treatment with concurrent cisplatin based chemotherapy, there is room for further improvements in local regional control. One approach to achieving this is to increase the dose of therapeutic radiation to the clinical target volume without exceeding the tolerance of the adjacent normal tissues. Modern radiotherapy techniques allow for better conformation of the high dose radiation volume to the clinical target volume by using external beam techniques (conformal radiation treatment and intensity modulated radiation treatment) and the use of tomotherapy is likely to be particularly advantageous in this regard. The mainstay of cervix cancer radiotherapy has always been and will likely remain the use of brachytherapy. Future improvements in the outcome of cervix cancer treated by radiotherapy are therefore likely to necessitate accurately combining intracavitary radiation treatment with intensity modulated external beam radiation treatment and particularly with the use of tomotherapy techniques.
