Spots Global Cancer Trial Database for Cognitive Fusion Prostate Biopsy With Biparametric Magnetic Resonance in the Detection of Prostate Cancer

Study Description

Brief Summary: The goal of this prospective observational study is to evaluate the diagnostic precision of the Biparametric Magnetic Resonance Imaging (bpMRI) in the detection of clinically significant prostate cancer (PCa) in patients with biochemical suspicion of prostate cancer with PSA (Prostate Specific Antigen) \> 4 ng/mL and a normal digital rectal examination and without a biopsy previous to the MRI. Secondary aims are: * Determine the validity as a diagnostic test of the first directed transrectal prostatic biopsy (cognitive fusion) versus systematic biopsy of 12 cylinders in patients with suspicious lesions in the bpMRI. * Develop a predictive nomogram that permits the reduction of the number of prostatic biopsies performed to patients with a low suspicion of prostate cancer in the bpMRI.

Detailed Description: In Spain, PCa is the most common cancer independently from gender and the third cause of death in man, below lung and colorectal cancer. Incidence and mortality increase progressively as age increases, hence, due to an older population, this is an outstanding sociosanitary concern. PCa generally is asymptomatic, diagnosis is based on prostate biopsy in man with an elevated Prostate Specific Antigen (PSA) in blood test and/or a pathologic digital rectal examination. Multiparametric Magnetic Resonance Imaging (MRImp) plays an important role in the diagnosis. It allows the visualization of the tumor, it values its agresitivity with a scale named "Prostate Imaging-Reporting and Data System" (PI-RADS v2 scale), and permits a directed biopsy to the suspicious lesion. This tecnique is expensive and very uncomfortable for the patient due its duration (40 minutes) and because it uses intravenous (iv) contrast. Due to these reasons, it is difficult to assume by the sanitary system to perform this technique to every patient with PCa suspicion. Biparametric MRI emerges as an alternative with a new protocol, performed with less image sequences (T2 and diffusion), cheaper, lasting less (just 15 minutes), and without the administration of iv contrast. Thus, this technique is more assumable by a public sanitary system.
