Improved Prostate Cancer Diagnosis - Combination of Magnetic Resonance Imaging and Biomarkers
Improved Prostate Cancer Diagnosis - Combination of Magnetic Resonance Imaging and Biomarkers
Prostate cancer has been the most common cancer 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. Due to the low accuracy of TRUS, a systematic biopsy is usually performed
 instead of targeted TRUS biopsy. As biopsy carries a risk of increase in complications, there
 is an increasing interest in developing more accurate non-invasive imaging modalities.

 This study will enroll 150 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. Multiparametric
 magnetic resonance imaging (mpMRI) at 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.
Inclusion Criteria:

 -  Age: 40 to 85 years

 -  Clinical suspicion of prostate cancer based on: serum level of PSA from 2,5 ng/ml to
 25 ng/ml in two following measurements and/or abnormal digital rectal examination

 -  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

 Exclusion Criteria:

 -  previous prostate biopsy in the last 6 months

 -  previous diagnosis of prostate carcinoma

 -  previous prostate surgeries, e.g. TURP (transurethral prostatic resection)

 -  symptomatic of acute prostatitis

 -  contraindications for MRI (cardiac pacemaker, intracranial clips etc)

 -  uncontrolled serious infection

 -  claustrophobia

 -  any other conditions that might compromise patients safety, based on the clinical
 judgment of the responsible urologist
