Patients with biochemical recurrence after primary treatment of prostate cancer presenting with =<4 metastases

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

Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy

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

Secondary objectives 1

  1. The secondary aim is obtaining more insight into the sensitivity of the PSMA-PET scan for detecting (oligo)metastases by low PSA-levels.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 9

  1. Histologically proven initial diagnosis of adenocarcinoma of the Prostate.
  2. Biochemical recurrence of prostate cancer following primary local prostate treatment (radical prostatectomy, primary radiotherapy or radical prostatectomy +/- prostate bed adjuvant salvage radiotherapy) according to the EAU guidelines 2018. BCR after surgery: PSA > O.lng/ml. BCR after radiotherapy: PSA nadir +2 ng/ml (after exclusion of possible bounce effect).
  3. Maximum 4 lesions (bone + lymph nodes) in total, without evidence of viscerai metastases. a. Nodal relapse (NI) in the pelvis on PSMA-PET scan with a maximum of 4 positive lymph nodes. The upper limit of the pelvis is defined as the aortic bifurcation. b. Nodal relapse (Ml) on PSMA-PET scan above the aortic bifurcation with a maximum of 3 positive lymph nodes. c. Bone relapse on PSMA-PET scan with a maximum of 3 lesions.
  4. Age > 18 years.
  5. PSMA-PET/CT scan or PSMA-PET/MRI within 60 days prior to randomization.
  6. PSA < 10 ng/ml.
  7. In case of chronic use of finasteride the PSA value should be < 5 ng/ml.
  8. WHO performance state 0-2.
  9. DSigned informed consent prior to registration/randomization.

Exclusion criteria 8

  1. Visceral metastases.
  2. PSA => 10 ng/ml.
  3. PSA-doubling time < 3 months.
  4. ADT or chemotherapy for recurrent PCa.
  5. Testosterone < 1.7 nmol/l.
  6. Painful metastases needed pain medication.
  7. Previous or concurrent invasive active cancers other than superficial non-melanoma skin cancers.
  8. Inability to understand the information on trial-related topics, to give informed consent or to fill out QoL questionnaires.
