RESUMO
INTRODUCTION: As a result of the COVID-19 pandemic in France, all non-emergency surgical activity has been cancelled since March 12, 2020. In order to anticipate the reinstatement of delayed interventions, surgical activity reduction analysis is essential. The objective of this study was to evaluate the reduction of urological surgery in adult during the COVID-19 pandemic compared to 2019. MATERIAL: The data regarding urological procedures realized in the 8 academic urological departments of Parisians centres (AP-HP) were compared over two similar periods (14-29 March 2019 and 12-27 March 2020) using the centralized surgical planning software shared by these centres. Procedure title, type of surgery and outpatient ratio were collected. The interventions were sorted into 16 major families of urological interventions. RESULTS: Overall, a 55% decrease was observed concerning urological procedures over the same period between 2019 and 2020 (995 and 444 procedures respectively). Oncology activity and emergencies decreased by 31% and 44%. The number of kidney transplantations decreased from 39 to 3 (-92%). Functional, andrological and genital surgical procedures were the most impacted among the non-oncological procedures (-85%, -81% and -71%, respectively). Approximatively, 1033 hours of surgery have been delayed during this 16-day period. CONCLUSION: Lockdown and postponement of non-urgent scheduled urological procedures decisions has led to a drastic decrease in surgical activity in AP-HP. Isolated kidney transplantation has been stopped (national statement). Urologists must anticipate for lockdown exit in order to catch-up delayed surgeries. LEVEL OF EVIDENCE: 3.

INTRODUCTION: Prostatic arterial embolization (PAE) is an experimental therapy for benign prostatic hyperplasia. Its feasibility is based on the knowledge of the pelvic arterial anatomy, and more specifically the prostate. The aim of this study was to describe the prostatic arterial supply: origins, distribution and variability. MATERIAL AND METHODS: We reviewed retrospectively, with two radiologists, 40 arteriographies of patients who underwent PAE in our center. With these observations of 80 hemipelvics, we described the number of prostatic arteries, their origins, their distributions and eventually their anastomoses with other pelvic arteries. RESULTS: There was one prostatic artery in 70% of the cases. It came from a common trunk for the prostate and the bladder in 55% of the cases, from the obturator artery in 17.5% of the cases, from the pudendal artery in 25% of the cases, from the intern iliac artery in 1% of the cases, and from the superior gluteal artery in 1% of the cases. The prostatic artery splitted in two branches (medial and lateral), with no anastomoses in 37% of the cases. Anastomoses with penile and rectal arteries were observed in 29% of the cases. CONCLUSIONS: For our 40 patients, we observed many variations of arterial prostatic anatomy. We proposed a classification in order to increase security and efficacy of PAE, and it should be validated with more patients. LEVEL OF EVIDENCE: 2.

OBJECTIVE: To evaluate the efficacy of a modification or initiation of treatment by a α-blocker in patients already medically treated for BPH-related LUTS, with persistent urinary symptoms. METHODS: This is a prospective observational study among general practitioners in France. Included patients were over 60 years of age with BPH-related LUTS who had been medically treated for at least 6 months. A treatment by an α-blocker was initiated or modified if the PGI-I (Patient Global Impression of Improvement) did not objective any improvement under treatment and the IPSS (International Prostate Symptom Score) was≥8. Patients were followed up between 1 and 3 months after inclusion. The primary endpoint was the frequency of unsatisfactory progression of patients, assessed by persistence of urinary symptoms under treatment (IPSS≥8 and PGI-I unchanged or worsened). Progress of LUTS (IPSS and PGI-I) following modification of treatment with α-blocker was also assessed at the follow-up visit. RESULTS: Three hundred and fifty-three physicians included 1449 patients between February 2, 2016 and March 9, 2017 (1380 patients were analyzed): the average age was 70.0±6.9 years ; the duration of the LUTS was 4.1±4.2 years; at inclusion, they received mainly plants (n=744; 53.9%) and α-blockers (n=463; 33.6%); the mean IPSS score was 16.4±6.7, it was not correlated with duration of SBAU; the mean PGi-I was 2.6±1.2. In total, 48.8% (612/1255) of patients had a non-satisfactory evaluation of the LUTS; 42.8% (591/1380) of patients had a modification of treatment according to the protocol: 385 (65.6%) had an initiation of a α-blocker, 202 (34.4%) had a modification of treatment by α-blocker (4 missing data). The α-blocker was monotherapy for 484 (81.9%) patients. At the follow-up visit (1 to 3 months), the average IPSS score was 7.7±4.8, significantly lower (18.7±6.1 at inclusion); the average PGI-I of 1.2±0.7 was significantly lower (3.5±0.8 at inclusion); the quality of life (Q8-IPSS) was significantly improved. For the 345 patients under plant extracts having changed for one α-blocker, as well as for the 67 patients under α-blocker having changed for another α-blocker, the 3 scores had decreased significantly. CONCLUSION: A systematic evaluation of medical treatment for BPH showed that 48.8% of patients medically treated for at least 6 months were not improved. A modification of treatment by an α-blocker (initiation or modification) can then significantly improve the LUTS.

OBJECTIVE: Assess the early morbidity after HOLEP, the urinary incontinence in particular, and specify its different types, evolution, and predictive factors. PATIENTS AND METHODS: We conducted an observational, analytical, retrospective, monocentric study including all patients undergoing surgery for benign prostatic hypertrophy (HBP) by HoLEP between November 2015 and January 2017. The data were collected pre-, per- and postoperatively. The follow-up was for 6 months. RESULTS: One hundred and seventy one patients were included. 23 patients (14.6%) had a complication according to Clavien-Dindo classification [4]: 19 (83%) Clavien 2, 1 (4%) Clavien 3b et 3 (13%) Clavien 4. At one month of the surgery, 64 (42.7%) patients had urinary incontinence of which 55 (86.1%) presented pure stress urinary incontinence. 18 (32.7%) were still incontinent at 6 months of the surgery. The delivered amount of energy during the surgery and the preoperative IIEF5 score were statistically significantly associated with the occurrence rate of stress urinary incontinence. There was no correlation between the surgeon's learning curve and the occurrence of incontinence. CONCLUSION: The occurrence rate of urinary incontinence post HoLEP might be related to the adopted surgical technique ; It is crucial to keep the patient well informed of the risk of this complication postoperatively.

INTRODUCTION: The incidence of cancer increases with age, especially for urological cancers. The frailty of the elderly persons may expose them to more postoperative complications resulting in prolonged hospitalization, increased morbidity or even increased mortality, and delayed or impossible return to normal life. In such cases, the benefit of surgery and therefore its realization can be questioned. PATIENTS AND METHOD: This article reports the experience of a pre-operative risk assessment in a population of elderly patients treated for urologic cancer. This retrospective study aims to report the feasibility and the main results of this systematic preoperative multi-professional evaluation. RESULTS: Between April 2016 and February 2017, 31 elderly patients were evaluated. The evaluation revealed: moderate to severe malnutrition in 59 % of cases, a patient judged from a geriatric point of view fit, intermediate or fragile in respectively 25 %, 35 % and 40 % of cases. This evaluation led to propose a modification of an element of care for 66 % of patients and to propose therapeutic abstention for only 3 patients. CONCLUSION: An evaluation whose purpose is to adapt to the physiological age of patients and their overall state of health, surgical treatment and postoperative management is feasible and seems to help unmask elements of fragility usually not detected.

OBJECTIVES: Our objective was to validate the VPSS (visual prostatic symptom score) score in the French language for the identification and monitoring of BPH-related LUTS in urological practice. METHODS: A prospective observational survey was carried out between September the 15th 2014 and July the 30th 2015 in urology practices. The first 4 consecutive patients aged over 60 years, with BPH-related LUTS requiring prescription of an alpha-blocker, were enrolled. We translated a "visual prostatic symptom score" (VPSS) into French and adapted it slightly. At the first visit and follow-up visit (1-3 months after the first visit), the patient completed 2 questionnaires: the French language version of the IPSS and the VPSS. RESULTS: Of the urologists contacted, 169 enrolled at least one patient and returned information; 550 questionnaires were included in the statistical analysis. The median IPSS and VPSS total scores, subscores and quality of life scores all decreased significantly (P<0.0001) between enrolment and the follow-up visit 1-3 months later. Correlations between the IPSS and VPSS at enrolment and the follow-up visit and their variation were all significant. Total VPSS was significantly correlated with total IPSS, as were the irritative, obstructive and quality of life subscores evaluated on the corresponding pictograms. CONCLUSIONS: This study showed the VPSS to be a simple and useful tool for identifying and monitoring BPH-related LUTS. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To confirm gender specific differences in pathologic factors and survival rates of urothelial bladder cancer patients treated with radical cystectomy. PATIENTS AND METHODS: We conducted a retrospective monocentric study on 701 patients treated with radical cystectomy and pelvic lymphadenectomy for muscle invasive bladder cancer. Impact of gender on recurrence rate, specific and non-specific mortality rate were evaluated using Cox regression models in univariate and multivariate analysis. RESULTS: We collected data on 553 males (78.9%) and 148 females (21.1%) between 1998 and 2011. Both groups were comparable at inclusion regarding age, pathologic stage, nodal status and lymphovascular invasion. Mean follow-up time was 45 months (interquartile 23-73) and by that time, 163 patients (23.3%) had recurrence of their tumor and 127 (18.1%) died from their disease. In multivariable Cox regression analyses, female gender was independently associated with disease recurrence (RR: 1.73; 95% CI 1.22-2.47; P=0.02) and cancer-specific mortality (RR=2.50, 95% CI=1.71-3.68; P<0.001). CONCLUSION: We confirmed female gender to be an independent negative prognosis factor for patients following a radical cystectomy and lymphadenectomy for an invasive muscle bladder cancer.

INTRODUCTION: Upper tract urinary carcinoma (UTUC) pT3 tumors are a heterogeneous entity including tumors invading the renal parenchyma, tumors with peripelvic fat invasion or peri-ureteral fat invasion. The aim of this study was to evaluate the prognostic significance of these three different groups of pT3 tumors. PATIENTS AND METHODS: Between 1998 and 2012, 205 patients with UTUC were operated in two centers, including 52 patients with pT3 tumor stage. pT3 tumors were divided into three groups: peri-ureteral fat invasion (pT3U, n = 16), peripelvic fat invasion (pT3G, n = 21), and renal parenchyma invasion (pT3P, n = 15). The prognostic significance of the type of tumor infiltration was evaluated on specific and disease-free survival. RESULTS: Median follow-up was 18.9 months [6-133.4]. In univariate analysis, renal parenchyma invasion was associated with a better prognostic in both specific (P = 0.026) and disease-free survival (P = 0.031) compared with peripelvic or peri-ureteral fat invasion. Mutivariate analysis retained the pT3 subgroup as an independant prognostic factor in both specific and disease-free survival (P = 0.02). CONCLUSION: pT3 tumors with renal parenchyma invasion had a better prognosis than those with peripelvic or peri-ureteral fat invasion. The heterogeneity of the pT3 group should be taken into account to improve the care of patients.

UNLABELLED: The objective of this study was to analyze the efficacy and safety of silodosin in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) in current urologic practice. METHOD: This was a prospective observational study conducted by 272 urologists on patients treated by silodosin for BPH. The parameters evaluated were the weighted IPSS score, the IPSS question 8 related to quality of life, the USP score and the Athens Insomnia Scale (AIS) measured at treatment initiation and after 3 months. RESULTS: Nine hundred and fourteen patients whose average age was 66 years with LUTS for 3.3 years were analyzed. After 3 months of treatment, a significant decrease in IPSS (from 16.2 ± 6.1 to 9.7 ± 5.5, P<0.0001) and USP score (from 10.6 ± 5.1 to 6 0 ± 4.6, P<0.0001) were observed, quality of life (from 67.1% to 14.4% of unsatisfied patients, P<0.0001) and sleep were significantly improved (from 49.2% to 28.9% patients with insomnia, P<0.0001). Among the patients, 21.2% experienced at least one adverse event. The most frequent were abnormal ejaculation (17.2%). And 7.1% discontinued the treatment for this reason. After 3 months of treatment silodosin was continued in 86.9% of patients. CONCLUSION: This large study confirmed the efficacy of silodosin in LUTS associated with BPH with a safety profile that does not affect patient satisfaction.

BACKGROUND: Little is known on factors predicting sunitinib toxicity. Recently, the condition of low muscle mass, named sarcopenia, was identified as a significant predictor of toxicity in metastatic renal cell cancer (mRCC) patients treated with sorafenib. We investigated whether sarcopenia could predict early dose-limiting toxicities (DLTs) occurrence in mRCC patients treated with sunitinib. METHODS: Consecutive mRCC patients treated with sunitinib were retrospectively reviewed. A DLT was defined as any toxicity leading to dose reduction or treatment discontinuation. Body composition was evaluated using CT scan obtained within 1 month before treatment initiation. RESULTS: Among 61 patients eligible for analysis, 52.5% were sarcopenic and 32.8% had both sarcopenia and a body mass index (BMI)<25 kg m(-2). Eighteen patients (29.5%) experienced a DLT during the first cycle. Sarcopenic patients with a BMI<25 kg m(-2) experienced more DLTs (P=0.01; odds ratio=4.1; 95% CI: (1.3-13.3)), more cumulative grade 2 or 3 toxicities (P=0.008), more grade 3 toxicities (P=0.04) and more acute vascular toxicities (P=0.009). CONCLUSION: Patients with sarcopenia and a BMI<25 kg m(-2) experienced significantly more DLTs during the first cycle of treatment.

BACKGROUND: The European Organization for Research and Treatment of Cancer (EORTC) risk tables and the Spanish Urological Club for Oncological Treatment (CUETO) scoring model are the two best-established predictive tools to help decision making for patients with non-muscle-invasive bladder cancer (NMIBC). The aim of the current study was to assess the performance of these predictive tools in a large multicentre cohort of NMIBC patients. METHODS: We performed a retrospective analysis of 4689 patients with NMIBC. To evaluate the discrimination of the models, we created Cox proportional hazard regression models for time to disease recurrence and progression. We incorporated the patients calculated risk score as a predictor into both of these models and then calculated their discrimination (concordance indexes). We compared the concordance index of our models with the concordance index reported for the models. RESULTS: With a median follow-up of 57 months, 2110 patients experienced disease recurrence and 591 patients experienced disease progression. Both tools exhibited a poor discrimination for disease recurrence and progression (0.597 and 0.662, and 0.523 and 0.616, respectively, for the EORTC and CUETO models). The EORTC tables overestimated the risk of disease recurrence and progression in high-risk patients. The discrimination of the EORTC tables was even lower in the subgroup of patients treated with BCG (0.554 and 0.576 for disease recurrence and progression, respectively). Conversely, the discrimination of the CUETO model increased in BCG-treated patients (0.597 and 0.645 for disease recurrence and progression, respectively). However, both models overestimated the risk of disease progression in high-risk patients. CONCLUSION: The EORTC risk tables and the CUETO scoring system exhibit a poor discrimination for both disease recurrence and progression in NMIBC patients. These models overestimated the risk of disease recurrence and progression in high-risk patients. These overestimations remained in BCG-treated patients, especially for the EORTC tables. These results underline the need for improving our current predictive tools. However, our study is limited by its retrospective and multi-institutional design.

INTRODUCTION: Upper urinary tract urothelial carcinoma (UTUC) is a rare disease. Thus, little evidence-based data are available to guide clinical decision-making. The aim of the study was to provide an overview of the currently available prognostic factors for UTUC. MATERIAL AND METHODS: A systematic literature search was conducted using the PubMed databases to identify original articles regarding prognostic factors in patients with UTUC. RESULTS: We divided the prognostic factors for UTUC in four different categories: clinical factors, preoperative characteristics, intraoperative/surgical factors and postoperative/pathologic factors. Prognostic factors described in order of importance are: tumor stage and grade, lymph node involvement, a concomitant cis, age at the diagnostic, lymphovascular invasion, tumor architecture and necrosis, tumor location and multifocality, gender. The impact of obesity, smoking and other comorbidities (ECOG, ASA) on outcomes has been recently reported but needs to be validated. The endoscopic approach of distal ureter management during radical nephroureterectomy has been shown to be at higher risk of bladder recurrence. CONCLUSION: The incorporation of such prognosticators into clinical prediction models might help to guide decision-making with regard to timing of surveillance, type of treatment, performance of lymphadenectomy, and consideration of neoadjuvant or adjuvant systemic therapies.

OBJECTIVES: The aim of this study was to evaluate the prognostic significance of the ureteral location of the upper tract urinary carcinoma (UTUC). PATIENTS AND METHODS: Between January 1998 and December 2007, 161 patients with UTUC were operated in our center. Tumors were located on renal pelvis in 51% of cases, on the ureter in 34% of cases and in both locations in 15% of cases. Nephroureterectomy was performed in 79.5% of cases (128/161) whereas a conservative treatment was performed in 20.5% of cases (33/161). RESULTS: In our series, 29.8% of patients had primary bladder cancer and 14.3% had synchronous bladder tumor. At a median follow-up of 42.5 months, 38.6% of patients developed bladder recurrence and 4.8% developed controlateral upper tract tumor. In multivariate analysis, ureteral location and existence of synchronous bladder tumor were independent prognostic factors of bladder recurrence (P=0.009 and P=0.025, respectively). Multivariate analysis retained T-stage and ureteral location as independent prognostic factors in both overall and disease-free survival (P=0.002 and P=0.0008 respectively for ureteral location). CONCLUSION: Ureteral location was an independent prognostic factor of bladder recurrence and was associated with a poorer prognosis.

BACKGROUND: The Hedgehog (Hh) signalling pathway functions as an organiser in embryonic development. Recent studies have shown constitutive activation of this pathway in various malignancies, but its role in bladder cancer remains poorly studied. METHODS: Expression levels of 31 genes and 9 microRNAs (miRNAs) involved in the Hh pathway were determined by quantitative real-time RT-PCR in 71 bladder tumour samples (21 muscle-invasive (MIBC) and 50 non-muscle-invasive (NMIBC) bladder cancers), as well as in 6 bladder cancer cell lines. RESULTS: The SHH ligand gene and Gli-inducible target genes (FOXM1, IGF2, OSF2, H19, and SPP1) were overexpressed in tumour samples as compared with normal bladder tissue. SHH overexpression was found in 96% of NMIBC and 52% of MIBC samples, as well as in two bladder cancer cell lines. Altered expression of miRNAs supported their oncogene or tumour-suppressor gene status. In univariate analysis, high expression levels of PTCH2, miRNA-92A, miRNA-19A, and miRNA-20A were associated with poorer overall survival in MIBC (P=0.02, P=0.012, P=0.047, and P=0.036, respectively). CONCLUSION: We observed constitutive activation of the Hh pathway in most NMIBC and about 50% of MIBC. We also found that some protein-coding genes and miRNAs involved in the Hh pathway may have prognostic value at the individual level.

BACKGROUND: In pT1-T3N0 urothelial carcinoma of the bladder (UCB) patients, multi-modal therapy is inconsistently recommended. The aim of the study was to develop a prognostic tool to help decision-making regarding adjuvant therapy. METHODS: We included 2145 patients with pT1-3N0 UCB after radical cystectomy (RC), naive of neoadjuvant or adjuvant therapy. The cohort was randomly split into development cohort based on the US patients (n=1067) and validation cohort based on the Europe patients (n=1078). Predictive accuracy was quantified using the concordance index. RESULTS: With a median follow-up of 45 months, 5-year recurrence-free and cancer-specific survival estimates were 68% and 73%, respectively. pT-stage, ge, lymphovascular invasion, and positive margin were significantly associated with both disease recurrence and cancer-specific mortality (P-values ≤ 0.005). The accuracies of the multivariable models at 2, 5, and 7 years for predicting disease recurrence were 67.4%, 65%, and 64.4%, respectively. Accuracies at 2, 5, and 7 years for predicting cancer-specific mortality were 69.3%, 66.4%, and 65.5%, respectively. We developed competing-risk, conditional probability nomograms. External validation revealed minor overestimation. CONCLUSION: Despite RC, a significant number of patients with pT1-3N0 UCB experience disease recurrence and ultimately die of UCB. We developed and externally validated competing-risk, conditional probability post-RC nomograms for prediction of disease recurrence and cancer-specific mortality.

OBJECTIVES: To evaluate the feasibility, tolerance and short-term efficacy of intra-prostatic UroLift(®) implants in four patients with symptomatic benign prostatic hyperplasia. PATIENTS AND METHOD: Four patients with symptomatic BPH, already treated with alpha-blockers, were consecutively treated with intra-prostatic UroLift(®) implants under general anaesthesia. A bladder catheter was placed postoperatively. Alpha-blocker therapy was withdrawn 7 days postoperatively. The clinical and morphological characteristics of the patients were noted. Low urinary tract (IPSS) and sexual symptoms (IIEF5, MSHQ-EjD), maximum urinary flow rate and post voiding residual volume were evaluated preoperatively and at 1 month. RESULTS: Median age was of 69 [52-74] years old and median prostatic volume of 50 cm(3) [40-80]. Median procedure time was of 11 minutes [6-15]. Intra- and postoperative outcomes were uneventful. At 1 month, the mean IPSS and IPSS-QOL improvement were of 46 % and 58 %, respectively. One patient reported no improvement in his urinary and sexual symptoms. In the other three patients, the maximum urinary flow rate was improved, the post voiding residual improved in two patients and similar in one. No alteration in erection or ejaculation functions was reported. CONCLUSIONS: In our initial experience, intra-prostatic UroLift(®) implant procedure seemed feasible, efficacious for LUTS and well tolerated, especially concerning sexual outcomes. Further study of the UroLift(®) implant in France is currently being planned.

BACKGROUND: Radiotherapy of prostate cancers, over the last few years, has been an alternative choice to radical prostatectomy in the case of localised cancers as well as being the preferred treatment in both advanced localised cancers and those of the elderly. A conventional course of prostate radiotherapy consisting of four to five sessions a week, lasts between 7 and 8 weeks plus about one week of preparation. MATERIALS AND METHODS: A systematic review of the scientific literature based on Pubmed, along with an exhaustive review of randomised studies presented at international congresses, have made it possible to analyse the numerous therapeutic regimens available other than the conventional normofractioned one (i.e. with doses per session ranging between 1.8 and 2.2 grays). RESULTS: Five randomised trials reported since 2005, plus several thousand patients treated by stereotaxic radiotherapy, have given rise to numerous scientific questions; these alternative hypofractioned courses (dose per fraction higher than 2.2 grays) have a potentially enhanced antitumoral efficacity along with the practical advantages of a shortened duration of radiotherapy. CONCLUSION: The aim of this analysis of the scientific literature on hypofractioning in prostate cancer radiotherapy is to gather all the scientific evidence we currently have at our disposal. Further mature results of future randomised trials will have to be examined before modifying current practice.

OBJECTIVES: To evaluate biological free survival in patients with locally advanced prostate cancer treated with radical prostatectomy (RP) as sole treatment, and to analyse predictive factors of recurrence. PATIENTS AND METHOD: We retrospectively studied patients treated between 1996 and 2006 for a pT3N0 prostate cancer with RP without any adjuvant treatment. The main endpoint was PSA relapse, defined as two successive elevations of PSA>0.2 ng/mL. An association between PSA free survival and PSA, Gleason score, pathological stage and surgical margins status was statistically assessed. RESULTS: A total of 147 patients were included. Median preoperative PSA was of 10 ng/mL. Pathological stage was pT3b in 30% of the cases and surgical margins showed cancer involvement in 63% of the cases. Gleason score was ≥3+4 in 74% of the cases. Postoperative PSA was undetectable in 121 (82%) patients. Median follow up following RP was of 5 years. The 5-year-PSA free survival was of 48%. Multivariate analysis showed that preoperative and postoperative PSA, as well as Gleason score were predictors of PSA relapse (P<0.05). In patients with undetectable postoperative PSA, 5-year-PSA free survival was of 56%. Seminal vesicle involvement and Gleason score ≥3+4 were the only independent predictors of PSA relapse. CONCLUSIONS: After RP for pT3N0 prostate cancer, the only predictive factors of recurrence were postoperative PSA and Gleason score. In case of undetectable postoperative PSA, surveillance seems acceptable if Gleason score is <3+4 and in the absence of seminal vesicle involvement.

OBJECTIVE: To evaluate the value of multiparametric MRI-targeted prostate biopsies in patients with suspected low-risk prostate cancer. PATIENTS AND METHOD: Patients with normal digital rectal examination and a PSA level between 4 and 10 ng/mL were prospectively included. A multiparametric MRI of the prostate was performed prospectively before the biopsies. 12-core randomized biopsies were performed, with additional targeted samples in each suspicious area identified on MRI. Detected cancers and their histological characteristics were compared between those two biopsy protocols. A micro focal cancer (MFC) was defined by the presence of less than 4mm of Gleason score 3+3 cancer on a single core. RESULTS: Seventy-one consecutive patients were included. The overall detection rate was of 53% (38/71). It was of 70% (26/37) in the presence of suspicious area on MRI versus 35% (12/34) in the absence of any suspicious area (P=0.004). MRI-targeted biopsies alone detected three cancers, none of which was a MFC. 12-core biopsies alone detected 14 cancers, including ten MFC (71%). In 21 patients, prostate cancer was detected by both the MRI-targeted and 12-core biopsies. The Gleason score in the MRI-targeted area was the highest Gleason score in 90% of the cases. It was high (>6) in 76% (16/21) of the patients. CONCLUSIONS: MRI-targeted biopsies detected less micro focal cancers than randomized 12-core biopsies. They did not seem however to decrease the detection of clinically significant cancers.

PURPOSE: to clarify the patterns of diagnosis and management of adult spermatic cord sarcoma. PATIENTS AND METHODS: between 1996 and 2009, seven patients with spermatic cord sarcoma were treated at Cochin hospital. After updating the pathological diagnosis according to the new classification of sarcoma we found that all patients had well-differentiated or dedifferentiated liposarcoma. We analysed their clinical presentation, management and carcinological outcome. RESULTS: the patients' age ranged from 51 to 77 years, and their follow-up from 7 to 68 months. In five patients, the diagnosis of well-differentiated liposarcoma (lipoma-like) with some dedifferentiated sectors was made straightaway. In the two other patients, the initial diagnosis was that of leiomyosarcoma, which was reconsidered as dedifferentiated liposarcoma according to the cytogenetical and immunohistochemical techniques available since 2005. In 6/7 patients, a tumour resection with an orchiectomy at the same time (four patients) or secondarily (two patients) was performed. In one patient, only a tumour resection, without orchiectomy, was made. Multiple recurrences were observed in the two patients who were initially diagnosed as leiomyosarcoma. They needed multiple reintervention. One of them died after 68 months of evolution, the other one was treated with chemotherapy and died after 47 months of evolution. Four patients are out of recurrence. One patient was lost to follow-up. CONCLUSION: the diagnosis of liposarcoma must be considered in all adult patients aged of more than 50 with fatty-shaped or containing fibomuscular nodules paratesticular tumours. The surgeon and the pathologist must be well informed and an early and wide resection of fatty masses of the sperm cord with negative margins is advocated. The quality of resection is crucial but its appreciation and carrying out are difficult. The role of complementary treatments, especially radiotherapy, has to be determined.
