Salvage Hypofractionated Accelerated Versus Standard Radiotherapy for Biochemical Failure After Prostatectomy
Comparison of Salvage Hypofractionated Accelerated Versus Standard Radiotherapy for Biochemical Recurrence After Radical Prostatectomy (SHARE Trial): a Prospective, Randomized Controlled, Open-label, Multi Center, Superiority Study
About This Trial
- This study is for men whose prostate cancer may be returning after surgery, indicated by rising PSA levels in their blood.
- Researchers are testing whether a shorter course of radiation with slightly higher daily doses works better at controlling the cancer and protecting quality of life compared to the standard, longer radiation schedule.
- If you join, you will be randomly assigned to receive either the shorter 26-treatment schedule or the traditional 33-treatment plan.
- Before considering this trial, you should know that your cancer must not have spread to other parts of your body, and you cannot have received radiation to the pelvic area in the past.
More Information
- Patients with a biochemical recurrence after radical prostatectomy for moderate- or high- risk prostate cancer are randomly assigned to hypofractionated, accelerated high dose radiation therapy group (65 Gy, 26 fractions) and a control group of standard treatment group (66 Gy, 33 fractions).
- The criteria for stratification at randomization include 1) risk groups, 2) androgen deprivation therapy, and 3) PSA before salvage radiation therapy, which affect biochemical recurrence.
- It is expected that hypofractionated, accelerated high dose radiation therapy will have a superiority in terms of biochemical control to conventional radiation therapy, and the present study would like to confirm this.
- In addition, we aimed to evaluate and compare the toxicity and quality of life index of two radiation therapy regimens.
