High Precision Imaging of Prostate Specific Membrane Antigen for Personalized Treatment in Prostate Cancer

Summary

This is an Investigator Initiated, non-commercial, single center, non-randomized, single arm, open label pilot study on 194 patients. The patients are affected by prostate cancer but in two different clinical settings. The first group is characterized by patients who are going to be operated of radical prostatectomy and they will undergo the study imaging preoperatively. The second group experiences biochemical relapse after primary treatment.

Eligibility

Inclusion criteria

Work-unit 1

* age \< 75 years of age, with histologically proven invasive adenocarcinoma of the prostate
* a risk of equal or more than 5% of lymph node metastasis (intermediate to high risk disease), according to the Briganti nomogram (1)
* scheduled to undergo radical prostatectomy with extended lymph node dissection

Work-unit 2

* histologically proven diagnosis of prostate cancer
* biochemical relapse (two consecutive PSA≥0.2 ng/ml) of prostate cancer following radical local prostate treatment
* WHO performance state 0-1
* age \> 18 years old

Exclusion criteria

Work-unit 1

* involvement of pelvic lymph nodes assessed by multi-parametric MRI
* evidence for bone metastasis assessed by bone scan (if PSA \> 20 ng/ml)

* previous pelvic irradiation or radical prostatectomy.
* other malignancy except adequately treated basal cell carcinoma of the skin diagnosed during the last 5 years
* 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.

Work-unit 2

* previous treatment with cytotoxic agent for PCa
* treatment during the past month with products known to influence PSA levels (e.g. fluconazole, finasteride, corticosteroids,…)
* disorder precluding understanding of trial information or informed consent
