Epithelioid Hemangioendothelioma (EHE) is an uncommon angiocentric vascular tumour. We present a case of an EHE of the left femoral vein, in a young woman, diagnosed after becoming symptomatic due to metastases. Limb is a rare localisation for this primary tumour. Diagnosis may be difficult, and aetiology is yet unknown. © 2012 European Society for Vascular Surgery. Source

Objective: A recent expert study (RAND Appropriateness Method (RAM)) including a panel of 12 European urologists reported that the PCA3 score may be instrumental in taking appropriate prostate biopsy (PBx) decisions, mainly for repeat PBx. This study determined the cost/benefit balance of introducing PCA3 in the decision-making for PBx in France. Methods: Two RAM models, without and with PCA3, were retrospectively applied to a sample of 808 French men who had PBx in 2010 (78% first, 22% repeat). Outcome measures included the proportion of PBx that could have been avoided (i.e., judged inappropriate) in the French sample according to both RAM models, and the estimated impact of application of these models on the annual number of PBx and associated costs for France (based on most recent published data). Results: Complete profiles were available for 698 men. In the model without PCA3, 2% of PBx were deemed inappropriate. Knowledge of PCA3 would have avoided another 7% of PBx. Repeat PBx would have been avoided in 5% of cases without PCA3 and in 37% with PCA3. For France, application of the RAM model including PCA3 would result in 18,345 fewer repeat PBx. It would be budget-neutral in the unlikely hypothesis of no complications or no costs incurred by complications and would save €1.7 million for a mean cost for complications of €100/procedure or €5 million for a mean cost for complications of €280/procedure, calculated based on US and Canadian data. Limitations: Limitations of the study are the theoretical nature of the analysis and the fact that PCA3 distributions had to be derived from other sources. Conclusions: Adoption of RAM expert recommendations including PCA3 for repeat PBx decisions in clinical practice in France would reduce the number of repeat PBx and control costs. © 2013 Informa UK Ltd All rights reserved.

Objective To establish a consensus on the utility of multiparametric magnetic resonance imaging (mpMRI) to identify patients for focal therapy. Methods Urological surgeons, radiologists, and basic researchers, from Europe and North America participated in a consensus meeting about the use of mpMRI in focal therapy of prostate cancer. The consensus process was face-to-face and specific clinical issues were raised and discussed with agreement sought when possible. All participants are listed among the authors. Topics specifically did not include staging of prostate cancer, but rather identifying the optimal requirements for performing MRI, and the current status of optimally performed mpMRI to (i) determine focality of prostate cancer (e.g. localising small target lesions of ≥0.5 mL), (ii) to monitor and assess the outcome of focal ablation therapies, and (iii) to identify the diagnostic advantages of new MRI methods. In addition, the need for transperineal template saturation biopsies in selecting patients for focal therapy was discussed, if a high quality mpMRI is available. In other words, can mpMRI replace the role of transperineal saturation biopsies in patient selection for focal therapy? Results Consensus was reached on most key aspects of the meeting; however, on definition of the optimal requirements for mpMRI, there was one dissenting voice. mpMRI is the optimum approach to achieve the objectives needed for focal therapy, if made on a high quality machine (3T with/without endorectal coil or 1.5T with endorectal coil) and judged by an experienced radiologist. Structured and standardised reporting of prostate MRI is paramount. State of the art mpMRI is capable of localising small tumours for focal therapy. State of the art mpMRI is the technique of choice for follow-up of focal ablation. Conclusions The present evidence for MRI in focal therapy is limited. mpMRI is not accurate enough to consistently grade tumour aggressiveness. Template-guided saturation biopsies are no longer necessary when a high quality state of the art mpMRI is available; however, suspicious lesions should always be confirmed by (targeted) biopsy. © 2013 The Authors.

Background Focal therapy has been introduced for the treatment of localised prostate cancer (PCa). To provide the necessary data for consistent assessment, all focal therapy trials should be performed according to uniform, systematic pre- and post-treatment evaluation with well-defined end points and strict inclusion and exclusion criteria. Objective To obtain consensus on trial design for focal therapy in PCa. Design, setting, and participants A four-staged consensus project based on a modified Delphi process was conducted in which 48 experts in focal therapy of PCa participated. According to this formal consensus-building method, participants were asked to fill out an iterative sequence of questionnaires to collect data on trial design. Subsequently, a consensus meeting was held in which 13 panellists discussed acquired data, clarified the results, and defined the conclusions. Outcome measurements and statistical analysis A multidisciplinary board from oncologic centres worldwide reached consensus on patient selection, pretreatment assessment, evaluation of outcome, and follow-up. Results and limitations Inclusion criteria for candidates in focal therapy trials are patients with prostate-specific antigen <15 ng/ml, clinical stage T1c-T2a, Gleason score 3 + 3 or 3 + 4, life expectancy of >10 yr, and any prostate volume. The optimal biopsy strategy includes transrectal ultrasound-guided biopsies to be taken between 6 mo and 12 mo after treatment. The primary objective should be focal ablation of clinically significant disease with negative biopsies at 12 mo after treatment as the primary end point. Conclusions This consensus report provides a standard for designing a feasible focal therapy trial. Patient summary A variety of ablative technologies have been introduced and applied in a focal manner for the treatment of prostate cancer (PCa). In this consensus report, an international panel of experts in the field of PCa determined pre- and post-treatment work-up for focal therapy research. © 2014 European Association of Urology. Source

Purpose: To assess the accuracy of prostate histoscanning (PHS) for spatial detection and localization of prostate cancer (PCa). Patients and Methods: Prospective, single center study from January to September 2012 was conducted. Inclusion criterion was biopsy confirmed PCa in patients scheduled for radical prostatectomy. In total, 98 patients were included in the study. Results of PHS were compared against whole-mount step sectioning by the Stanford technique. A lower limit of 0.1 cm3 was used for PHS. A dedicated 12-sector form was used for spatial correlation. The urologist and pathologist were blinded for each other's results. Sensitivity, specificity, and receiver operating characteristic curves were calculated with a logistic regression model for covariates. Results: PHS performance for detection of PCa lesions ≥0.1 cm3 had sensitivity of 60%, specificity of 66%, and area under the curve (AUC) of 0.63. Posterior and anterior sectors achieved sensitivity of 77%, specificity of 39%, and 28% and 84%, respectively. The model containing PHS positivity within a given sector reached sensitivity of 73.4%, specificity of 65.7%, and AUC of 0.75. In a ogistic regression model, the performance of PHS was affected by sector location, rectal distance, index, and total cancer volume (all P<0.0001) and bladder fullness (P=0.02). The best PHS accuracy was present in midposterior sectors. Conclusions: PHS has a potential for clinical practice, especially if PHS positivity within given sectors is taken into account. A trained operator is important. More studies are necessary to test different detection limits in various clinical settings, such as targeted biopsies and image guided focal therapy. © 2014, Mary Ann Liebert, Inc. Source
