Brief Summary:

Metastatic prostate cancer has traditionally been regarded as an incurable dissemination of disease, and treatment is focused on delaying progression rather than eliminating all tumor burden. Local therapies, and specifically radiotherapy, have been directed at quality of life endpoints and not at improving survival. However, advances in imaging and systemic therapy have identified a population of 'oligometastatic' patients who have a lower burden of metastatic disease (usually ≤5 lesions), who may present an exception. This condition is hypothesized to occupy the hinterland between incurable metastatic disease and locoregional disease, where micrometastatic disease is assumed to exist and yet remain eradicable. Oligometastases can be detected using standard imaging but the sensitivity of these exams is very low for patients with a PSA below 10 ng/ml. In France, FCH PET imaging is now routinely available in a large majority of cancer centres. More recently, PSMA PET imaging has been developed.

Since most oligometastases are now discovered at a time when conventional imaging is unable to detect metastases, we must rely on the literature regarding purely biochemically-relapsing prostate cancer patients. Three strategies have been explored: (i) observation until symptoms develop, (ii) early intermittent Androgen Deprivation Therapy (IADT) and (iii) continuous Androgen Deprivation Therapy (ADT). Recent data suggest that, of the three strategies, early intermittent ADT was superior in term of overall survival to observation in controlling metastatic prostate cancer, and this effect was similar in the biochemically-relapsing prostate cancer patient population.

This phase III study will explore the role of salvage pelvic IG-IMRT combined with intermittent ADT (IADT) in pelvic oligometastatic patients in prolonging the first failure-free interval between the first and the second intermittent ADT courses.

Condition or disease Intervention/treatment Phase
Prostate Cancer Oligometastasis Drug: IADT Combination Product: IADT + radiotherapy Not Applicable

Detailed Description:

Screening procedures will be performed up to three months before starting IADT. After obtaining informed consent, patients will be randomly allocated to one of two groups:

Experimental group: IADT + IG-IMRT Control group: IADT

In both study arms, the first injection of IADT will be administered in hospital on the day of randomization. The overall duration of IADT will be six months.

In the experimental group, patients will receive radiotherapy three months after the first injection of IADT.

The overall duration of radiotherapy will be three months.

The overall duration of IADT will be six months. It will be administered three months, +/- 15 days prior to the first day of radiotherapy. At the completion of the six-month treatment period, a non-treatment interval will start if :

there is no evidence of clinical disease progression and the PSA level is ≤ 4.00 ng/ml If the PSA subsequently rises above 0.20 ng/ml and is confirmed by a second measurement at least three weeks later, PET/CT imaging will be repeated every 6 months until a clinical failure is detected or until the PSA rises above 4.00 ng/ml.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically-proven prostate adenocarcinoma
  • Age ≥ 18 years
  • Performance Status 0-1
  • Prior radical prostate treatment (surgery and/or radiotherapy)
  • ≤ 5 metastatic pelvic lymph nodes detected by FCH-PET or PSMA-PET
  • Upper limit of metastatic lymph nodes: aortic bifurcation
  • If ADT has been previously administered to the patient, at least 12 months must have elapsed between the predicted duration of the last injection and inclusion of the patient in the study. For this category of patients, serum testosterone must be higher than 6 nmol/L (50 ng/L) prior to inclusion
  • Biochemical relapse (according to the European Association of Urology guidelines) is defined by :

Following radical prostatectomy (RP), biochemical recurrence (BCR) is defined by two consecutive rising PSA values > 0.20 ng/ml After primary radiation therapy (RT), the Radiation Therapy Oncology Group (RTOG) and American Society for Radiation Oncology Phoenix Consensus Conference definition of PSA failure is any PSA increase > 2.00 ng/ml higher than the PSA nadir value, regardless of the serum concentration of the nadir.
