High Dose Rate (HDR)Prostate Brachytherapy With Vitesse tm
Abstract
High Dose Rate (HDR) temporary prostate brachytherapy offers a precise form of dose escalation for prostate cancer. Needles are placed, the position is confirmed and treatment is delivered. Previously High Dose Rate prostate brachytherapy was performed under TransRectal UltraSound (TRUS) guidance but planned with Computed Tomography (CT) imaging which introduced a source of error through needle displacement while transporting and repositioning patient. Recently Varian has introduced a one-step procedure where both implant and planning are based on UltraSound imaging and performed without patient repositioning. This planning system is approved by Health Canada and is commercially available.
This study will use High Dose Rate brachytherapy to treat 20 men. Treatment will be planned with TransRectal UltraSound and validated using Computed Tomography imaging.
Conditions: Prostate Cancer, Interstitial Radiation, High Dose Rate Brachytherapy, Ultrasound-based Planning Compared to CT-based Planning.
Primary outcome: Accuracy of Needle Tip Identification on TransRectal UltraSound Compared to Computed Tomography.
Enrollment: 20 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 20 participants or records.
