PURPOSE: To evaluate the negative predictive value (NPV) of a negative prostate multi-parametric magnetic resonance imaging (mpMRI) in ruling out clinically significant prostate upon 12-core systematic biopsy. METHODS: We retrospectively reviewed 114 men evaluated at our institution who underwent systematic 12-core biopsy within 1 year of a negative prostate mpMRI. Clinicopathologic features were evaluated and NPV was calculated for detection of clinically significant (Gleason ≥ 7) cancer...

PURPOSE: The purposes of this study were to investigate the pattern of relapse in patients with low- or intermediate-risk prostate cancer treated with 19-Gy high-dose-rate brachytherapy (HDR-BT) and to calculate the dose received by the area of recurrence. METHODS AND MATERIALS: Patients included in this analysis were treated under a Phase II randomized trial that evaluated the role of 19-Gy HDR-BT monotherapy in low- and intermediate-risk prostate cancers. Multiparametric prostate MRI and prostate biopsy were performed in patients with suspicious local recurrence...

CONTEXT: Local and regional recurrence after radical prostatectomy (RP) can be treated using salvage radiotherapy (SRT). If the recurrence can be delineated on diagnostic imaging, this could allow for increasingly individualized SRT. OBJECTIVE: This systematic review aimed at evaluating the evidence regarding the usefulness of positron emission tomography (PET) and magnetic resonance imaging (MRI) in identifying local and regional recurrences, with the aim to further individualize the SRT treatment...

OBJECTIVE: To identify the clinical and MRI variables predictive of biochemical recurrence (BCR) after robotic assisted radical prostatectomy (RALP) in patients who underwent multi-parametric 3 Tesla prostate MR Imaging. METHODS: An IRB approved, HIPAA compliant, a single arm observational study with 3T mpMRI prior to RALP from December 2009 until March 2016 was performed. Clinical, MRI, pathological information and clinical outcome were compiled. Biochemical recurrence was defined as PSA greater > 0...

A 78-year-old man with a history of benign prostatic hyperplasia presented with double vision, facial pain, altered taste and headache for 7 weeks. Neurological exam was notable for palsies of the right V, VI, VII and XII cranial nerves. An expansive clival mass and multiple lesions in the vertebra were found on MRI. Radionuclide studies showed extensive tumour burden in his liver and peritoneum. His serologies showed normal carcinoembryonic antigen and carbohydrate antigen 19-9 levels and modestly elevated prostate-specific antigen, which was a red herring...

Salvage brachytherapy after a first prostate radiation therapy is an emerging technique, which has to be considered in the therapeutic armamentarium in the clinically challenging context of patients with isolated local failure from prostate cancer who may still be considered for cure. These occult failures are more and more frequently diagnosed at an early stage, thanks to targeted biopsies and advances in imaging modalities, such as multiparametric MRI and PET-CT. Salvage brachytherapy benefits from the implantation accuracy of brachytherapy procedures using 3D dosimetry and has resulted in more than 50% tumour control rates with long-term...

RATIONALE AND OBJECTIVES: This study aimed to assess a novel method of three-dimensional (3D) co-registration of prostate magnetic resonance imaging (MRI) examinations performed before and after prostate cancer focal therapy. MATERIALS AND METHODS: We developed a software platform for automatic 3D deformable co-registration of prostate MRI at different time points and applied this method to 10 patients who underwent focal ablative therapy. MRI examinations were performed preoperatively, as well as 1 week and 6 months post treatment...

OBJECTIVE: The objective of this study is to determine the frequency of clinically significant cancer (CSC) in Prostate Imaging Reporting and Data System (PI-RADS) category 3 (equivocal) lesions prospectively identified on multiparametric prostate MRI and to identify risk factors (RFs) for CSC that may aid in decision making. MATERIALS AND METHODS: Between January 2015 and July 2016, a total of 977 consecutively seen men underwent multiparametric prostate MRI, and 342 underwent MRI-ultrasound (US) fusion targeted biopsy...

Prostate cancer lesions smaller than 0.5 m(3), or Gleason pattern 3, are likely clinically insignificant. Clinically significant disease is often limited to a single index lesion. Focal ablation targets this index lesion, maintains oncological control, and minimizes complications by preserving healthy prostate tissue. Template mapping biopsy or multiparametric MRI-targeted biopsies are used to identify appropriate index lesions. Multiple energy modalities have been tested, including high-intensity frequency ultrasound, cryoablation, laser ablation, photodynamic therapy, focal brachytherapy, radiofrequency ablation, irreversible electroporation...

Marc A Bjurlin, Samir S Taneja
Prostate MRI is commonly used in the detection of prostate cancer to reduce the detection of clinically insignificant disease; maximize the detection of clinically significant cancer; and better assess disease size, grade, and location. The clinical utility of MRI seems to apply to men with no prior biopsy, who have had a previous negative biopsy, and men who are candidate for active surveillance. In conjunction with traditional clinical parameters and secondary biomarkers, MRI may allow more accurate risk stratification and assessment of need for prostate biopsy...

Until recently, prostate biopsy for the detection of prostate cancer has been performed transrectally and in an untargeted sampling fashion. Consequently, the procedure has suffered a small but significant risk of severe morbidity through infection, and low diagnostic accuracy, with undergrading and missed diagnosis being common. MRI is revolutionizing prostate cancer diagnosis by improving detection accuracy via targeted biopsy. Transperineal biopsy is eradicating sepsis as a risk of prostate biopsy, while avoiding the need for broad-spectrum or combination prophylactic antibiotics...

The goals of this meta-analysis were to assess the effectiveness of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in patients with prostate carcinoma (PCa) and to explore the risk profiles with the highest benefit. Systematic electronic searched were conducted in database. We used patient-based and biopsy-based pooled weighted estimates of the sensitivity, specificity, and a summary receiver operating characteristic (SROC) curve for assessing the diagnostic performance of DCE. We performed direct and indirect comparisons of DCE and other methods of imaging...

AIM: To determine the significance and need for investigation of incidental prostatic uptake in men undergoing (18)F-labelled fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for other indications. METHODS: Hospital databases were searched over a 5-year period for patients undergoing both PET/CT and prostate magnetic resonance imaging (MRI). For the initial analysis, the prostate was divided into six sectors and suspicious or malignant sectors were identified using MRI and histopathology reports respectively...

Background: Literature data suggest that multi-parametric Magnetic Resonance Imaging (MRI), including morphologic T2-weigthed images (T2-MRI) and functional approaches such as Dynamic Contrast Enhanced-MRI (DCE-MRI), Diffusion Weighted Imaging (DWI) and Magnetic Resonance Spectroscopic Imaging (MRSI), give an added value in the prostate cancer localization and local staging. Methods: We performed a systematic review of literature about the role and the potentiality of morphological and functional MRI in prostate cancer, also in a multimodal / multiparametric approach, and we reported the diagnostic accuracy results for different imaging modalities and for different MR coil settings: endorectal coil (ERC) and phased array coil (PAC)...
