Target Recruitment

Inclusion Criteria

Signed informed consent to participate in the study

Group 2: Prostate adenocarcinoma confirmed by biopsy or histopathological examination

Group 2: After radical treatment

Group 2: For patients after radical prostatectomy: with at least two PSA measurements ≥0.2 ng/ml not earlier than 6 weeks after radical prostatectomy or PSA≥0.1 with PSAdt (PSA doubling time) <3 months. PSA in at least two consecutive tests within the last 6 months before eligibility (last determination within 6 weeks before eligibility, not necessary to do on the day of the visit))

Or: for patients after radical radiotherapy: biochemical recurrence defined as nadir PSA + 2 ng/ml (we consider the lowest PSA concentration during ADT + 2ng/ml)

Or: if radical treatment included the inclusion of hormone therapy: three consecutive PSA increases, at least two of which measured with an increase of at least 50% above the nadir level, and a current PSA > 2 ng/mL

Age ≥18 years

Group 1: patients with a diagnosis or high probability of CRC of intermediate and high risk according to ISUP, in whom it is planned to implement radical treatment

Group 1: Prostate adenocarcinoma confirmed by biopsy and histopathology or negative BAC with mpMR and PSA results indicating n high risk of RGK

Group 1: Results indicative of intermediate-risk RGK (Gleason score 7 or cT2b or PSA 10-20 ng/ml) or high (Gleason score > 7 or cT2c or PSA > 20 ng/ml) risk according to ISUP

Group 1: Creatinine value that allows the study to be performed safely PET/MR with contrast agent: creatinine less than or equal to 1.5x the upper limit of normal, creatinine clearance >60 mL/min

Group 1: Performed pelvic/prostate mpMR examination, no earlier than 90 days prior to inclusion in the project

Group 1: Status after prostate BAC (results may be inconclusive)

Group 2: Patients with CRC after radical treatment, with recurrence of biochemical according to EAU criteria, in whom further treatment is planned, and the imaging/molecular test results may change the therapeutic decision therapeutic decision:

Exclusion Criteria

Lack of informed consent to participate in the study

Age < 18 years

The presence of metallic foreign bodies/implants/prostheses/stimulators, etc. inside the body, the possession of which is a contraindication to the 3T MR examination

Claustrophobia

Patient sizes preventing PET/MR study due to gantry diameter. In cases of doubt, consultation with the research center Bialystok or Bydgoszcz, respectively, is advisable

Known contraindications to the use of radiopharmaceutical products or excipients (e.g., renal failure and allergy to the ingredients of the preparation)

Hormone therapy (applies to group 1 only)

Treatment for malignant neoplasm unrelated to the prostate gland (skin cancer) within the last 5 years.
