NCT04302454

Brief Summary

The overall aim of this project is to test the hypothesis that the addition of ADT to metastasis-directed radiotherapy (MDRT) in well-selected PCa patients with oligo-metastatic disease prolongs the metastases progression-free survival (MPFS) compared to MDRT alone.

Outcome Measures

Primary Outcomes (1)

  • Metastases progression-free survival (MPFS)

    The primary aim of this project is to test the hypothesis that the addition of ADT to MDRT in well-selected PCa patients with oligo-metastatic disease (OM) prolongs the metastases progression-free survival (MPFS) compared to MDRT alone

  • Minimal 1 lesion and maximum 4 lesions (bone + lymph nodes) in total, without evidence of visceral metastases.
  • Nodal relapse (N1) in the pelvis on PSMA-PET/CT with a maximum of 4 positive lymph nodes. The upper limit of the pelvis is defined as the aortic bifurcation.

  • Bone relapse on PSMA-PET/CT with a maximum of 3 lesions.
  • Combination of a, b, c with a maximum of 4 metastases.
  • Age \> 18 years.
  • Recent PSMA-PET/CT scan within 60 days prior to randomization.
  • PSA \< 10 ng/ml.
  • In case of chronic use of finasteride the PSA value should be \< 5 ng/ml.
  • WHO performance state 0-2.
  • Signed informed consent prior to registration/randomization.

You may not qualify if:

  • Visceral metastases.
  • PSA ≥ 10 ng/ml.
  • PSA-doubling time ≤ 3 months.
  • ADT or chemotherapy for recurrent PCa.
  • Testosterone \< 1.7 nmol/l
  • Painful metastases needed pain medication (\> level 1 pain medication) .
  • Invasive active cancers other than superficial non-melanoma skin cancers.
  • Inability or unwillingness to understand the information on trial-related topics, to give informed consent or to fill out QoL questionnaires.
