Prospective Study on the Sparing of Organs at Risk in High Dose Rate Brachytherapy for Cervix Cancer
After 60 Gy are delivered with Intensity Modulated Radiation Therapy (IMRT), the
brachytherapy in high dose rate will deliver 15 Gy to the CTVhr (high risk CTV) in two
A clinical examination and an RMN are performed at the end of the external radiation to
evaluate the residual tumoral volume. Two HDR brachytherapy sessions are then performed.
During the first session, a CT-Scan and an RMN will be performed after the fletcher
application. A second CT-Scan will be performed during the second treatment session to
create new volumes and to improve organs at risk sparing.
Observational Model: Case-Only, Time Perspective: Prospective
Evaluation of the sparing of organs at risk with a delineation at each session and the CTVhr volume modification
To record the irradiated volumes modifications of each OAR at each session and the CTV volume modification.
At 8 weeks of external radiotherapy
