Eligibility
Key inclusion criteria
- Histologically proven initial diagnosis of adenocarcinoma of the prostate

- Biochemical relapse of prostate cancer following radical local prostate treatment
(radical prostatectomy, primary radiotherapy or radical prostatectomy +/- prostate bed
adjuvant/ salvage radiotherapy) according to the EAU guidelines 2016.

- Following radical prostatectomy, patients with a biochemical relapse are eligible in
case a nodal relapse is detected in the pelvis even in the absence of prior
postoperative prostate bed radiotherapy (adjuvant or salvage).

- In case of a suspected local recurrence following primary radiotherapy, a biopsy
should confirm local recurrence and patients with a confirmed local recurrence are
eligible in case they also undergo a local salvage therapy. If imaging rules out local
relapse, patients are eligible.

- Nodal relapse in the pelvis on choline, PSMA or FACBC PET-CT with a maximum of 3
positive nodal lymph nodes. The upper limit of the pelvis is defined as the aortic
bifurcation.

- WHO performance state 0-1

- Age >18 years

- Absence of any psychological, familial, sociological or geographical condition
potentially hampering compliance with the study protocol and follow-up schedule; those
conditions should be discussed with the patient before registration in the trial

- Before patient registration/randomization, written informed consent must be given
according to ICH/GCP, and national/local regulations.
Minimum age
18 Years
Maximum age
No limit
Sex

Can healthy volunteers participate?
No
Key exclusion criteria
- Bone or visceral metastases

- Para-aortic lymph node metastases (above the aortic bifurcation)

- Local relapse in the prostate gland or prostate bed not suitable for a curative
treatment

- Previous irradiation of the pelvic and or para-aortic nodes

- Serum testosterone level <50ng/dl or 1.7 nmol/L at time of randomization

- Symptomatic metastases

- Lymph node metastases in previously irradiated areas resulting in dose constraint
violation

- Contraindications to pelvic radiotherapy (chronic pelvic inflammatory bowel disease)

- Contraindications to androgen deprivation therapy

- PSA rise while on active treatment with (LHRH-agonist, LHRH-antagonist, anti-androgen,
estrogen

- Previous treatment with cytotoxic agent for PCa

- Treatment during the past month with products known to influence PSA levels (e.g.
fluconazole, finasteride, corticosteroids,…)

- Other active malignancy, except non-melanoma skin cancer or other malignancies with a
documented disease-free survival for a minimum of 3 years before randomization.

Summary
Brief summary
A proportion of prostate cancer (PCa) patients develop relapse following curative local
treatment. Regional nodal recurrence is an emerging clinical situation since the introduction
of new molecular imaging methods in the restaging of recurrent prostate cancer. More
specifically, a subgroup of these patients is being diagnosed with a recurrence confined to
the regional lymph nodes and limited in number (oligorecurrence) using choline or PSMA
PET-CT. As there are no specific treatment recommendations for these type of patients,
different treatment approaches are currently used, mostly focusing on local ablative
treatments using radiotherapy or surgery. These treatments are coined metastasisdirected
therapy (MDT). MDT in combination with or without temporary ADT could delay the subsequent
risk of progression, and even cure limited regional nodal recurrences. Consequently, lifelong
palliative ADT, with its toxicity and excess in non-cancer mortality might be postponed.

The proposed trial randomizes patients with oligorecurrent nodal prostate cancer following
primary PCa treatment to either metastasis-directed therapy (MDT) (salvage lymph node
dissection, sLND or stereotactic body radiotherapy, SBRT) or MDT plus whole pelvis
radiotherapy (WPRT: 45 Gy in 25 fractions).
