Purpose: To obtain an overview of the degree of discrepancy between current clinical practice of prostate magnetic resonance imaging (MRI) in France and recommendations. Materials and methods: A brief survey was sent to 1229 members of the French society of urology in order to identify their indications of prostate MRI and its impact on patient management. The urologists were asked to answer several questions regarding age, practice modality, prostate MRI examinations (technique, indication before first biopsy, second biopsy, cancer staging, active surveillance, recurrence, focal therapy) and quality of reports. Results: A total of 445 responses were received (participation rate of 36%). The mean delay for obtaining an appointment for prostate MRI ranged between 15-30 days in 54%. Fifty-four percent of MRI reports contained a PIRADS score and 23% a Likert score. The indications of multiparametric-MRI were tumor detection/location prior to repeat biopsy (90%), cancer staging (85%), management of patients under active surveillance (85%), selection of candidates to focal therapy (63%), tumor detection/location in biopsy naïve patients (53%), detection of local recurrence after radical (51%). Only 119 urologists (28.6%) had access to image fusion (MRI and transrectal ultrasound) and 351 (85.4%) used cognitive fusion. Mostly, targeted biopsies are done by urologists alone (nearly 80%), a very few are done by radiologists (8%) or by the two of them in collaboration (12%). Conclusion: The majority of urologists consider that prostate MRI is essential for the management of patients with prostate cancer. Practices are ahead of recommendations particularly before the first biopsy and in active surveillance. © 2016 Editions françaises de radiologie. Published by Elsevier Masson SAS.

Aims: To evaluate the angiographic and clinical outcome of patients undergoing paclitaxel-eluting stent (PES) implantation for unprotected left main coronary artery (ULMCA) stenosis in a "real-world" multicentre, prospective registry. Percutaneous coronary intervention (PCI) is an increasingly utilised method of revascularisation in patients with ULMCA. Methods and results: A prospective registry including all patients with a significant (>50%) ULMCA stenosis. Of 151 such patients, the target lesion involved the distal bifurcation in 100 patients (66%), which was treated predominantly by a "provisional T-stenting" strategy. In the distal ULMCA disease group, 72% had only one stent implantation while 28% had multiple (either two or three) stents implanted. At a median follow-up of 1,123±80 days, cardiac death occurred in five patients (3.3%) and major adverse cardiac and cerebrovascular events (MACCE) in 32 patients (21.2%). The three-year survival rate was 93.3%. Conclusions: In the drug-eluting stent era, paclitaxel-eluting stent implantation of ULMCA stenosis provided excellent immediate and long-term results in this selected population, suggesting that this approach may be considered as a safe and effective alternative to CABG for selected patients with ULMCA who are treated in experienced institutions performing large numbers of PCI procedures. © Europa Edition 2011.

Background/purpose: Laparoscopic hepatectomies have seen a worldwide proliferation. Major anatomic resections, which were initially considered unsuitable for laparoscopy, are currently confined to a few centers of expertise. The aim of this study was to discuss the current trends and techniques in laparoscopic major hepatectomy in Europe. Methods: The prospective databases of ten European centers were combined to provide answers to a questionnaire that had been addressed to all European teams known to perform laparoscopic liver surgery. Results: Between 1996 and 2011 a total of 2245 laparoscopic liver resections have been carried out, of which 495 (22 %) were major resections. The proportion of laparoscopic right and left hepatectomies varied between 4 and 40 % of all major hepatectomies of the same type. Benign, primary malignant and metastatic lesions were, respectively, 22.4, 19.6 and 58 % of all indications. The different techniques and approaches, as regards hand assistance, hepatic inflow and outflow control, liver mobilization and concomitant colectomies, are discussed. Conclusions: To date, an important level of experience of laparoscopic liver resection has been accumulated in Europe, and experience of major hepatectomies is constantly increasing. However, they remain technically very demanding procedures which should be confined to expert surgeons who have already acquired considerable experience with simpler laparoscopic liver resections. © 2012 Japanese Society of Hepato-Biliary-Pancreatic Surgery and Springer.

Purpose: To evaluate the influence of preoperative factors on the survival of patients diagnosed with upper tract urothelial carcinoma (UTUC) who underwent a radical nephroureterectomy (RNU).Methods: A multicentre retrospective study was performed on all patients with UTUC who underwent a RNU. Multiple preoperative criteria were tested as prognostic factors for cancer-specific survival (CSS) using univariate and multivariable Cox regression analyses.Results: Overall, 476 patients with a median age of 69.2 (IQR 60.8–76.5) years were included. The median follow-up was 27.8 months (IQR 10.5–49.3). At the time of diagnosis, 400 (84.1 %) patients presented with symptoms and 76 patients (15.9 %) were asymptomatic. Renal failure, altered general health, a preoperative locally advanced tumour and multifocal disease appeared to be preoperative prognostic factors for CSS (p = 0.01, 0.03, 0.001 and 0.03, respectively) in the univariate analysis. Only renal failure (p = 0.03), a preoperative locally advanced tumour (0.004), and multifocal locations (p = 0.01) were confirmed as independent factors of CSS in the multivariate analysis. The independent prognosticators of definitive muscle-invasive stage and non-organ-confined disease were preoperative renal failure (p = 0.02, 0.027, respectively), locally advanced stage (p < 0.001, <0.001, respectively) and positive cytology (p = 0.006, 0.003 respectively). Female gender was independent factor only for prediction of final non-organ-confined disease (p = 0.007). The addition of these parameters in our preoperative complex model permitted the prediction of muscle-invasive or locally advanced disease in 65.3 and 67.2 % of patients, respectively.Conclusions: Patients with preoperative impaired renal function, locally advanced stage and multifocal tumours before RNU had worse survival outcomes compared to other patients. © 2014, Springer-Verlag Berlin Heidelberg.

Objective To evaluate the impact of 'hereditary-like' status in upper tract urothelial carcinoma (UTUC) on the survival of patients who have undergone radical nephroureterectomy (RNU) and adjuvant chemotherapy. Patients and Methods A multicentre retrospective study was performed on all patients with high-risk UTUC who underwent RNU and adjuvant cisplatin-based chemotherapy. Using a patient risk identification tool, we distinguished tumours suspected to be hereditary from sporadic tumours and compared survival rates. Results A total of 112 patients with a median age of 67 years were included. Hereditary-like tumour status was detected in 35 patients (31.3%), while 77 patients (68.7%) had sporadic tumours. The median age was significantly younger in the hereditary-like tumour group (56.0 vs 69.8 years, P < 0.001). Overall survival (OS) after chemotherapy was significantly better in the group with hereditary-like tumours than in the group with sporadic tumours (5-year OS: 48.2 vs 32%; P = 0.008). The cancer-specific survival (CSS) rate was significantly better in the group with 'hereditary-like' tumours than in the group with sporadic tumours (5-year CSS: 58 vs 35%; P = 0.006). Although there was a trend in favour of the hereditary-like tumours, we observed no significant difference regarding progression-free survival (PFS) between the two groups (5-year PFS: 71 vs 52%; P = 0.07). Conclusion Adjuvant chemotherapy after RNU improves survival outcomes in patients with hereditary-like UTUC compared with those with sporadic tumours. © 2013 The Authors.

To evaluate the pathologic features of surgical specimens after radical prostatectomy in patients with low-risk prostate cancer fulfilling the strictest pathologic selection criteria for active surveillance. Retrospective analysis of 10 785 consecutive radical prostatectomy performed in 10 university hospitals (January 2003 through December 2008). A total of 919 patients fulfilled the following unique and very stringent criteria: T1c, prostate-specific antigen (PSA) <10 ng/mL, a single positive biopsy, tumor length <3 mm, and Gleason score <7. Clinico-biologic and pathologic data at diagnosis and after radical prostatectomy, prostatic and tumor volume, pathologic Gleason score and stage, positive surgical margins, insignificant prostate cancer, and PSA outcomes were recorded. Median age was 63 years. Mean prebiopsy PSA level was 6.2 ng/mL. At radical prostatectomy, Gleason score was upgraded in 34% of patients, including 1.2% Gleason score 8-9. Pathologic stages were pT2 in 87.3%, pT3 in 11.1%, and pT4 in 1.4% of cases. Extraprostatic extension was found in 12.5%. Only 26% of patients had "insignificant" tumors. Biochemical recurrence-free survival at 5 years was 92.3%. There was no significant difference in survival between patients with "significant" and "insignificant" tumors (90.1% vs 93.4%; P = .06). Despite of a stringent selection of patients with low-risk prostate cancer, active surveillance definition included a significant proportion of patients with upstaged (about 12%) and upgraded (about one-third) disease at diagnosis. Only a quarter of active surveillance patients have a pathologically confirmed "insignificant" cancer. © 2012 Elsevier Inc. All Rights Reserved.

To assess whether non-suspicious multiparametric magnetic-resonance imaging (mpMRI) was associated with no cancer or indolent prostate cancer (PCa) in subsequent biopsies.Retrospective analyses of a prospective database were conducted between 2009 and 2013. It included men with an abnormal digital rectal examination and/or prostate-specific antigen levels <20ng/mL and a non-suspicious multiparametric MRI (Likert score <3). Participants underwent a systematic 12-extended-core biopsy ultrasound protocol (STD). Indolent PCa was defined as a single core with a Gleason score of 6 (3+3) and a cancer-core length of 4mm.Seventy-eight patients with a negative MRI were included in the study; median patient age was 62years (IQR 50-74). Median PSA level was 7.15ng/mL, with a median PSA density of 0.15. The digital rectal examination was abnormal in eight cases. From MRI, 53 patients were Likert 2, 25 patients were Likert 1, and median prostate volume was 56.5mL. From biopsies, no cancer was found in 92.3% (n=72). PCa was histologically confirmed in six patients (7.7%): five cases were indolent (as defined above); only one patient had a cancer core of 5mm long, with a Gleason score of 6 (3+3). All six patients were within the low-risk group according to the DAmico classification.Men with non-suspicious mpMRI are likely to have no or indolent PCa in subsequent biopsies.
