NCT06204341

Brief Summary

The goal of this clinical trial is to combine several optimized treatments of high risk prostate cancer. The main question to answer is: is it safe to combine these optimized treatments.

  • patients will be irradiated on the prostate and (elective) lymph nodes more concentrated but with fewer hospital visits (hypofractionation)
  • the tumor will get a higher dose
  • androgen deprivation therapy will be reduced as much al possible preventing side effects Researchers will compare oncological outcome and toxicity.
