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...

Brief Summary

Official Title: “Economic Evaluation of Image Guided Radiation Therapy For Prostate Cancer”

Condition Keyword(s):

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.

Study Type: Interventional

Study Design: Other, Randomized, Open Label, Active Control, Parallel Assignment, Safety/Efficacy Study

Intervention(s) in this Clinical Trial

  • Procedure: Control position by 3DOBI before the fraction

Outcome Measures for this Clinical Trial

Primary Measures

  • 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 Measures

  • 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)

Criteria for Participation in this Clinical Trial

Inclusion Criteria:

  • prostate adenocarcinoma
  • intermediate / high risk group

  • treatment by conformal radiotherapy (including or not IMRT), with or without androgen deprivation

Exclusion Criteria:

  • pelvic irradiation
