[Radiotherapy for cervix carcinomas: clinical target volume delineation]. / Délinéation des volumes cibles anatomocliniques pour la radiothérapie des cancers du col utérin.

ABSTRACT

Concurrent chemoradiation followed by brachytherapy is currently the standard treatment for locally advanced cervix carcinomas. Modern radiation techniques require planning based on 3D images, and therefore an accurate delineation of target volumes. The clinical target volume (CTV) used for the different phases of treatment are now well defined, but are not always easy to delineate on a CT scan which is currently the standard examination for simulation in radiotherapy. MRI and PET-CT are routinely performed at diagnosis, and can be used to improve the accuracy of the delineation. The objective of this review is to describe the definitions and recommendations of CTV in the treatment of cervical cancer.
