The cognitive fusion prostate biopsy using a smart phone in the diagnosis of prostate cancer. Arch Esp Urol. 2020 Dec;72(10):1026-1031 Authors: Yalcin S, Kaya E, Ebiloglu T, Akay S, Zor M, Sarıkaya S, Yilmaz S, Bedir S Abstract OBJECTIVES: In this research, we designed a cognitive fusion(CF) prostate biopsy(PB) (CFPB) technique by examining the multiparametric MRI of prostate (MP_MRI-P) images in a smart-phone near the trans-rectal ultrasound (TRUS) device, and examined the results. METHODS: Between January 2011 and January 2017, a total of 344 men who had PB enrolled in this study. Group 1 had a minimum of a 12-core standard TRUS PB (TRUSPB). Group 2 had CFPB while examining the MP_ MRI-P images in a smartphone near the TRUS device. A minimum 12 cores + cognitive targeted 1-3 biopsy were taken. The detection of Pca and significant Pca in group 1 and 2 were evaluated and compared. Then, the effect of MP_MRI-P findings on the detection of prostate cancer (Pca) and significant Pca were evaluated. RESULTS: Group 1 and 2 included 138 and 206 patients. After the PB, 45(32.8%) and 33(23%) patients ingroup 1, and 74(35.9%) and 60(29%) patients in-group 2 were detected to have Pca and significant Pca, respectively (p=0.001 for both). Higher PIRADS caused significant detection of Pca and significant Pca (p=0.004 and 0.002). Nodule in MP_MRI-P caused significant detection of Pca and significant Pca (p=0.001 and 0.001). Especially, when PSA was

Radioactive seeds implanted via ultrasound or computed tomography (CT) guidance are minimally invasive and facilitate quick recovery. Transrectal ultrasound-guided 125I seed implantation assisted by a transperineal plane template is standard for early-stage prostate carcinoma, with a hi...

Authors: Morrison BF, Aiken WD, Reid G, Mayhew R, Hanchard B Abstract Several studies suggest race-based health disparities in men with low-risk prostate cancer (PCa), with African American males having poorer oncological outcomes. We sought to determine the prevalence and predictors of pathological upgrading and upstaging in Jamaican men with low-risk PCa treated with radical prostatectomy (RP). Data on 141 men who met the National Comprehensive Cancer Network criteria for low-risk PCa and underwent RP at a single institution were reviewed. All men had a transrectal ultrasound-guided biopsy. Pre-operative clinical...

CONCLUSIONS: The largest variation of intrafraction prostate displacement was observed along the AP direction. Throughout most of the treatment time, the prostate moved within a few millimeters. The extent of prostate displacement increased for longer monitoring times. During most of the tracking time, the prostate position was within the clinically safety margins.

AbstractPurposePIRADS v2 stipulates that dynamic contrast-enhanced (DCE) imaging be used to categorize diffusion-weighted-imaging (DWI) score 3 (DWI 3) peripheral zone (PZ) lesions as PIRADS score 3 (PIRADS 3; DCE −) or PIRADS 4 (DCE +). It’s controversial for the value of DCE in improving clinically significant prostate cancer (csPCa) detection. We aimed to figure out whether DCE improves csPCa detection and explore new available measures to improve csPCa detection.Patients and methodsWe retrospectively enrolled 375 patients who underwent mp MRI before MRI/ultrasound (US) fusion-targeted biopsy (TB) wit...

ConclusionWe confirmed that the Cormio nomogram can be used to predict the risk of PCa in patients at increased risk. Implementation of the nomogram in clinical practice will better define its role in the patient ’s counselling before prostate biopsy.

AbstractProstate cancer is the fourth most common cancer and population-based screening programmes are being increasingly adopted worldwide. Screening-positive patients undergo routine transrectal ultrasound (TRUS)-guided systematic biopsy, which is the current diagnostic standard for prostate cancer. However, systematic biopsies suffer from poor sensitivity, especially for the tumors of the anterior prostate and apex as well as in large volume glands. In the past decade, MRI-guided targeted biopsies have come up, which utilize the multiparametric capability of MRI to target lesions for sampling. MRI/TRUS fusion biopsies c...

ConclusionIn the present study, we found that MRI-TBx potentially benefits the detection of overall and clinically significant PCa compared with TRUS-Bx in patients with a suspicion of PCa. Furthermore, in patients with initial biopsy, MRI-TBx had a significantly higher detection rate of overall PCa and a potentially higher detection rate of clinically significant PCa. While for patients with prior negative biopsy, we did not detect significant differences in overall and clinically significant PCa between two groups. More large and multicenter RCTs are further required.

AbstractThe aim of this study was to test an interactive up-to-date meta-analysis (iu-ma) of studies on MRI in the management of men with suspected prostate cancer. Based on the findings of recently published systematic reviews and meta-analyses, two freely accessible dynamic meta-analyses (https://iu-ma.org) were designed using the programming language R in combination with the package “shiny.” The first iu-ma compares the performance of the MRI-stratified pathway and the systematic transrectal ultrasound-guided biopsy pathway for the detection of clinically significant prostate cancer, while the second iu-ma ...
