Study summary

Focused stereotactic radiation treatment of localized prostatic adenocarcinoma. in order to quantify the delay between the focused treatment and the salvage procedure.

Read the detailed description

Focused stereotactic radiation treatment of localized prostatic adenocarcinoma. in order to quantify the delay between the focused treatment and the salvage procedure.

Second objectives : objectives: prostate-specific antigen (PSA) response, MRI response, toxicity (CTCAEv4), quality of life (International Prostate Symptom Score (IPSS) and The International Index of Erectile Function (IIEF5) scores).

Method At first: Multiparametric Magnetic resonance imaging (MRI) - 12 biopsies within the whole gland.

Placement under endorectal ultrasound control of 4 fiducials at least 2 cm spaced.

Treatment : CyberKnife radiation treatment delivering 36.25 Gy in 5 fractions, in 10 days. Tracking using the 4 fiducials. Critical organs: Rectal and bladder wall: V35\<2cc. Bladder neck and urethra: V35\<1cc.

Salvage treatments: in such a context, salvage surgery or salvage intensity modulation radiation therapy (IMRT) treatments can in theory remain valid and safe options.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 22, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
