Image Guided Radiation Therapy For Prostate Cancer

August 13, 2026 updated by: Gustave Roussy, Cancer Campus, Grand Paris

Economic Evaluation of Image Guided Radiation Therapy For Prostate Cancer

During the 7 to 8 weeks of conformal radiotherapy for prostate carcinoma, the prostate has an intra-pelvic motion which is not detectable by the conventional portal imaging. This prostate motion may lead to a mistargeting, which possibly decreases the local control. On the other hand, the new 3D on board imaging (3D OBI) allows to localize the target but is expensive. The cost/effectiveness ratio is not well established, as well as the frequency of using such imaging during the course of radiation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Prostate position under the LINAC is checked by 3D OBI (mainly cone-beam imaging, CBI) performed before the fraction.
To validate the optimal strategy of IGRT for prostate adenocarcinoma based on 2 and 5 year-disease free survival rates (events= biochemical failure or death).

Secondary Outcome Measures

Outcome Measure
Rectal and bladder, acute and late toxicities (CTCAE, SOMA-LENT)
Cost comparison and cost/effectiveness analysis
2 and 5 years clinical relapse free survival rates
Lack of dose in the prostate in case of decreasing the CBI frequency (using the 1rst arm for testing)
