NCT05258383

Brief Summary

In image-guided radiotherapy (IGRT), the repeated and increasingly intensive use of on-board positioning imaging, using 2D or 3D Mega-Volt (MV) or kilo-Volt (kV) imaging devices (cone-beam or CBCT scanners), is leading the international medical community to question the potential impact of these additional doses delivered to the patient, especially in at-risk populations such as children and young adults. The doses delivered to the patient by positioning imaging are still relatively unknown, due to the lack of experimental means and software available in clinical routine to easily and accurately evaluate these doses. The main objective is to estimate by personalized Monte Carlo calculation the physical doses delivered to the patient's organs by the onboard imaging systems during their radiotherapy treatment. The obtained imaging doses will be compared according to different irradiation scenarios commonly used in clinical routine as well as according to the treated location.

Outcome Measures

Primary Outcomes (1)

  • Global analysis of 3D mapping of physical doses delivered to organs by positioning imaging.

    Global analysis of 3D mapping of physical doses delivered to organs by positioning imaging. These analyses will aggregate the Doses Volumes Histograms (HDV) by organs of interest as well as the mean dose to 10% (D10), 50% (D50) and 90% (D90) metrics for these same organs to form an individual dosimetric report.

Sampling MethodProbability Sample
Study Population

Female patients (Lung Neoplasm, Breast Cancer, Cancer Ear Nose and Throat / ENT); Male patients (Lung Neoplasm, Pelvic Neoplasm, Cancer Ear Nose and Throat / ENT); Pediatric cancer patients.

You may qualify if:

  • IGRT (Image Guided Radiation Therapy) treatments considered: lung, pelvic (prostate), breast, ENT and pediatric cancers
  • Treatment modalities: linac + daily kV-CBCT (kilo-Volt ConeBeam CBCT) and linac + weekly kV-CBCT + daily 2-Dimensional-kilo-Volt (2D-kV) (adult: lung, prostate, breast, Ear Nose and Throat (ENT); pediatric: neuro, ENT, thorax and abdomen); Cyberknife + daily 2D-kV (adult lung); Tomotherapy + daily MV-CBCT (Mega-Volt ConeBeam CBCT) (adult prostate, breast, ENT; pediatric ENT, thorax and abdomen)

You may not qualify if:

  • Patient who has undergone a treatment discontinuation or modification (re-planning) of treatment with an impact on the IGRT protocol.
  • Patient for which details on the imaging procedures used during treatment or DICOM files (DICOM CT, DICOM RTstruct) are incomplete will not be included
