Prostate Magnetic Resonance Imaging in Patient With Previous Negative Biopsies (PROMANEG)

April 16, 2018 updated by: Peter Boström, Turku University Hospital

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. While, as many as 47% of the ultra-sound guided biopsies may be false negative and biopsies carry 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 previous negative biopsies and clinical suspicion of prostate cancer due to serum level of PSA higher than 2.5 ng/ml or abnormal digital rectal examination (DRE) or patients in active surveillance due to low risk prostate carcinoma. Anatomical magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) at 3 Tesla (T) magnetic field using surface coils will be used to non-invasively predict the presence or absence of prostate cancer. In addition to routine 12-core TRUS biopsies, targeted TRUS guided biopsy based on MRI findings will be performed.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Diagnostic accuracy of multiparametric MRI in prostate cancer diagnosis
Time Frame: 3 mounths
Multiparametric MRI is performed in patients with previous negative biopsies with clinical suspicion of prostate cancer (elevated PSA and/or abnormal DRE) or in patients in active surveillance due to low risk prostate carcinoma. The accuracy will be determined using the results from transrectal ultrasound guided biopsies.
