Brief Summary

The shortcoming of the pre-biopsy prostate MRI approach is the recommendation to biopsy all men post-MRI even if there is no lesion seen in MRI, ie. risk of PCa is very low. Therefore, the primary objective of this trial is to compare if there is a difference between significant cancer detection rate in men undergoing prostate biopsies after MRI scan compared to men undergoing post-MRI prostate biopsies only after a shared decision-making based on prostate cancer risk estimation. The trial will enrol 600 patients. The primary outcome measure is the the proportion of men with CSPCa (Gleason 4+3 prostate cancer or higher) between the control and intervention arms at baseline. Eligible men are randomised 1:1 in two groups. In control arm in all men prostate biopsies are performed after MRI whereas in intervention arm prostate biopsies are performed only after a shared decision-making between urologist and the patient and the discussion is based on risk estimation.

Study Arms (2)

Control

NO INTERVENTION

After IMPROD bpMRI all men undergo prostate biopsies. In men with Likert scores of 1-2, TRUS guided systematic biopsies are performed. In men with Likert 3-5 score, in addition to systematic biopsies, two targeted biopsies are taken from each lesion (up to two lesions).

Intervention

EXPERIMENTAL

After IMPROD bpMRI prostate biopsies are performed according to shared decision-making by the treating urologist and the patient. If biopsies are to be performed, in men with IMPROD bpMRI likert scores of 1-2, 12-core systematic TRUS guided biopsies are performed and in men with Likert 3-5 score lesions systematic biopsies are performed and two targeted biopsies are taken from each lesion (up to two lesions). If biopsies are not performed, men are referred for a PSA follow-up.

Diagnostic Test: A shared decision making

Interventions

Based on prostate cancer risk calculation (age, usage of 5-ARI medication, baseline PSA, IMPROD bpMRI Likert, prostate volume) a shared decision making whether to perform prostate biopsies or not

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age: 18 years or older
  • Language spoken: Finnish
  • Clinical suspicion of prostate cancer, based on: serum level of PSA from 2,5 ng/ml to 20 ng/ml and/or abnormal digital rectal examination according to the referral physician
  • Mental status: Patients must be able to understand the meaning of the study
  • Informed consent: The patient must sign the appropriate Ethics Committee (EC) approved informed consent documents in the presence of the designated staff

You may not qualify if:

  • previous diagnosis of prostate cancer
  • any contraindications for MRI
  • any other conditions that might compromise patient's safety, based on the clinical judgment of the responsible urologist
  • bilateral hip prosthesis
