Brief Summary:

Prostate cancer has been the most common neoplastic disease in men in Finland over the last ten years. Prostate-specific antigen (PSA) plays an important role in screening of prostate cancer. However, PSA has a limited sensitivity and specificity for prostate cancer detection. Commonly, the diagnosis of prostate cancer is done by transrectal ultrasonography (TRUS) guided biopsy. Because of the low accuracy of TRUS a systematic biopsy is usually performed instead of targeted TRUS biopsy. As biopsy carries a significant risk of complications, there is an increasing interest in developing more accurate non-invasive imaging modalities.

This prospective multi-institutional study will enroll 400 men with clinical suspicion of prostate cancer due to higher serum level of PSA than 2.5 ng/ml and/or abnormal digital rectal examination. Anatomical magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) at 1.5/3 Tesla (T) magnetic field using surface coils will be used to non-invasively predict the presence or absence of prostate cancer. Targeted TRUS guided biopsy based on MRI findings will be performed in addition to routine twelve core TRUS biopsy. Moreover, selected serum and urine biomarkers as well as biomarkers extracted from fresh biopsy sample will be collected and correlated with the presence or absence of prostate cancer.

Arm Intervention/treatment
Experimental: MRI guided prostate biopsy
prostate biopsy after MR-imaging
Procedure: prostate biopsy

Primary Outcome Measures :
  1. Diagnostic accuracy of biparametric MRI (T2wi+DWI) in prostate cancer diagnosis [ Time Frame: 18 months ]
    Biparametric MRI (T2wi+DWI) is performed in patients with a clinical suspicion of prostate cancer (elevated PSA and/or abnormal DRE). The accuracy will be determined using the results from transrectal ultrasound guided biopsies.

Secondary Outcome Measures :
  1. Diagnostic accuracy of selected tissue, urine, and blood biomarkers for prostate cancer diagnosis [ Time Frame: 18 months ]

    Accuracy of selected tissue, urine, and blood biomarkers for prostate cancer diagnosis will be evaluated.

    Gene expression profile of selected genes will be compared between cancer and non-cancer cases to investage optimal gene expression panels for prostate cancer risk prediction. Similarly serum and urine marker profiles are compared between cancer and non-cancer cases

Other Outcome Measures:
  1. Evaluation of bacterial strains [ Time Frame: 18 months ]
    The bacterial resistance towards antibiotics is evaluated.
