CONTEXT: Correct assessment of tumour stage is crucial for prostate cancer (PCa) management. OBJECTIVE: To assess the diagnostic accuracy of magnetic resonance imaging (MRI) for local PCa staging and explore the influence of different imaging protocols. EVIDENCE ACQUISITION: We searched the PubMed, Embase, and Cochrane databases from 2000 up to August 2014. We included studies that used MRI for detection of extracapsular extension (ECE; T3a), seminal vesicle invasion (SVI; T3b), or overall stage T3 PCa, with prostatectomy as the reference standard...

BACKGROUND: A significant proportion of prostate cancers (PCas) are missed by conventional transrectal ultrasound-guided biopsy (TRUS-GB). It remains unclear whether the combined approach using targeted magnetic resonance imaging (MRI)-ultrasound fusion-guided biopsy (FUS-GB) and systematic TRUS-GB is superior to targeted MRI-guided in-bore biopsy (IB-GB) for PCa detection. OBJECTIVE: To compare PCa detection between IB-GB alone and FUS-GB + TRUS-GB in patients with at least one negative TRUS-GB and prostate-specific antigen ≥4 ng/ml...

CONTEXT: Detection of clinically significant prostate cancer (PCa) is a major challenge. It has been shown that multiparametric magnetic resonance imaging (mpMRI) facilitates localisation of PCa and can help in targeting prostate biopsy. OBJECTIVE: To systematically review the literature to determine the diagnostic accuracy of mpMRI in the detection of clinically significant PCa. EVIDENCE ACQUISITION: The Pubmed, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched from January 1, 2000 to September 30, 2014, using the search criteria "prostate OR Pca OR PSA OR prostatic OR prostate cancer" AND "MR OR NMR OR NMRI OR MRI OR magnetic resonance OR ADC OR DWI OR DCE OR diffusion weighted OR dynamic contrast OR multiparametric OR MRSI OR MR spectroscopy"...

CONTEXT: The current standard for diagnosing prostate cancer in men at risk relies on a transrectal ultrasound-guided biopsy test that is blind to the location of the cancer. To increase the accuracy of this diagnostic pathway, a software-based magnetic resonance imaging-ultrasound (MRI-US) fusion targeted biopsy approach has been proposed. OBJECTIVE: Our main objective was to compare the detection rate of clinically significant prostate cancer with software-based MRI-US fusion targeted biopsy against standard biopsy...

BACKGROUND: The current diagnosis of prostate cancer (PCa) uses transrectal ultrasound-guided biopsy (TRUSGB). TRUSGB leads to sampling errors causing delayed diagnosis, overdetection of indolent PCa, and misclassification. Advances in multiparametric magnetic resonance imaging (mpMRI) suggest that imaging and selective magnetic resonance (MR)-guided biopsy (MRGB) may be superior to TRUSGB. OBJECTIVE: To compare the diagnostic efficacy of the magnetic resonance imaging (MRI) pathway with TRUSGB...

Prostate cancer is often associated with metastases to bone and/or soft tissue. The progression to metastatic castrate-resistant prostate cancer is a seminal event in disease progression affecting treatment decisions. A multidisciplinary group was convened to review the currently available imaging guidelines for metastatic disease in prostate cancer and found no consensus on eligibility criteria, type of imaging modality, and the frequency of scanning for detecting metastatic disease. The aim of this review was to present the recommendations from the group to identify optimal strategies for early identification of metastases in patients with prostate cancer...

BACKGROUND: The current diagnostic strategy using transrectal ultrasound-guided biopsy (TRUSGB) raises concerns regarding overdiagnosis and overtreatment of prostate cancer (PCa). Interest in integrating multiparametric magnetic resonance imaging (MRI) and magnetic resonance-guided biopsy (MRGB) into the diagnostic pathway to reduce overdiagnosis and improve grading is gaining ground, but it remains uncertain whether this image-based strategy is cost-effective. OBJECTIVE: To determine the cost-effectiveness of multiparametric MRI and MRGB compared with TRUSGB...

BACKGROUND: Gleason scores from standard, 12-core prostate biopsies are upgraded historically in 25-33% of patients. Multiparametric prostate magnetic resonance imaging (MP-MRI) with ultrasound (US)-targeted fusion biopsy may better sample the true gland pathology. OBJECTIVE: The rate of Gleason score upgrading from an MRI/US-fusion-guided prostate-biopsy platform is compared with a standard 12-core biopsy regimen alone. DESIGN, SETTING, AND PARTICIPANTS: There were 582 subjects enrolled from August 2007 through August 2012 in a prospective trial comparing systematic, extended 12-core transrectal ultrasound biopsies to targeted MRI/US-fusion-guided prostate biopsies performed during the same biopsy session...
