Résumé: Objectif: Évaluer la rentabilité de la tomographie par émission de positons à la (18F)-fluorocholine (TEP-fluorocholine) pour localiser la récidive après traitement local du cancer prostatique et son impact éventuel sur les indications d’un traitement local de rattrapage. Patients et méthodes: Une TEP-fluorocholine couplée à la tomodensitométrie a été réalisée chez 28 patients pris en charge pour un adénocarcinome prostatique en progression biochimique. La concentration sérique médiane d’antigène spécifique de la prostate (PSA) était de 3ng/mL (0,34–93) et 17 patients (60,7 %) recevaient une hormonothérapie au moment de l’examen. Au total, 18 patients de la cohorte étaient potentiellement candidats à une radiothérapie de rattrapage. Résultats: Une lésion pathologique d’un point de vue métabolique a été mise en évidence chez 11 patients (39,3 %). Il n’y avait chez 17 patients (61 %) aucune lésion suspecte. La concentration sérique médiane de PSA était de 2,4ng/mL (0,34–36) en l’absence de lésion hypermétabolique suspecte contre 6,75ng/mL (1,21–93) en cas de lésion suspecte visualisée (p =0,04). Sur 18 patients potentiellement candidats à une radiothérapie de rattrapage, l’examen donnait des arguments pour une irradiation chez cinq en montrant une fixation centropelvienne isolée (28 %). Chez un patient, l’examen montrait des métastases faisant récuser la radiothérapie. Après prostatectomie, l’examen n’était positif que chez un seul patient candidat à une radiothérapie (9 %) sous la forme d’une récidive maligne locorégionale de la région anastomotique. Conclusion: L’examen était positif chez près du tiers des patients éligibles à une radiothérapie. L’évaluation prospective de son impact clinique est en cours. [ABSTRACT FROM AUTHOR]

Seminoma is a highly curable disease; therefore, long-term morbidity of oncological treatment represents a crucial stake. In view of the considerable advances made in radiotherapy in the past decade, we aim to shed light on current and future strategies that hold promises for the management of stage II seminoma., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Adoption of high-content omic technologies in clinical studies, coupled with computational methods, has yielded an abundance of candidate biomarkers. However, translating such findings into bona fide clinical biomarkers remains challenging. To facilitate this process, we introduce Stabl, a general machine learning method that identifies a sparse, reliable set of biomarkers by integrating noise injection and a data-driven signal-to-noise threshold into multivariable predictive modeling. Evaluation of Stabl on synthetic datasets and five independent clinical studies demonstrates improved biomarker sparsity and reliability compared to commonly used sparsity-promoting regularization methods while maintaining predictive performance; it distills datasets containing 1,400-35,000 features down to 4-34 candidate biomarkers. Stabl extends to multi-omic integration tasks, enabling biological interpretation of complex predictive models, as it hones in on a shortlist of proteomic, metabolomic and cytometric events predicting labor onset, microbial biomarkers of pre-term birth and a pre-operative immune signature of post-surgical infections.

We hereby report the case of a 40-year-old male, who initially underwent a left inguinal orchiectomy for a stage Is mixed germ cell tumor achieving an R0 status. His follow-up is mainly noticeable for many recurrences affecting exclusively the inguinal and suprapubic soft tissues. The recurrences occurred early, and almost always contained immature tissue upon pathologic reading, which has never been described in the medical literature before.

Background: There is no definitive evidence of the prognosis impact of histological variants (HVs) in patients who undergo surgical resection of a nonmetastatic renal cell carcinoma (nm-RCC) with venous tumor thrombus (TT)., Objective: To investigate the impact of HVs on the prognosis of patients with nm-RCC with TT after radical surgery., Design Setting and Participants: Patients who underwent radical nephrectomy with the removal of the venous TT for an nm-RCC were included in a retrospective study., Outcome Measurements and Statistical Analysis: Three groups were identified: clear cell (ccRCC), papillary (pRCC), and chromophobe (chRCC) RCC. The primary outcome measures (disease-free and overall survival [OS]) were assessed using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate Cox proportional hazard models were used to study the impact of HVs on survival., Results and Limitations: A total of 873 patients were included. The histological subtypes were distributed as follows: ccRCC in 780 cases, pRCC in 58 cases, and chRCC in 35 cases. At the time of data analysis, 612 patients were recurrence free and 228 had died. A survival analysis revealed significant differences in both OS and recurrence-free survival across histological subtypes, with the poorest outcomes observed in pRCC patients ( p  < 0.05). In a multivariable analysis, pRCC was independently associated with worse disease-free survival and OS (hazard ratio [HR]: 1.71; p  = 0.01 and HR: 1.24; p  = 0.04), while chRCC was associated with more favorable outcomes than ccRCC (HR: 0.05; p  < 0.001 and HR: 0.02; p  < 0.001). A limitation of the study is its retrospective nature., Conclusions: In this multicentric series, HVs appeared to impact the medium-term oncological prognosis of kidney cancer with TT., Patient Summary: This study investigated the differences in oncological outcomes among histological variants (clear cell, papillary, and chromophobe) in a cohort of nonmetastatic renal cell carcinoma patients with venous tumor thrombus extension. We observed that these histological variants within this specific subgroup exhibit distinct outcomes, with papillary renal cell carcinoma being associated with the worst prognosis., (© 2024 The Authors.)

Purpose: Testicular cancer (TC) predominantly affects young men and early detection enhances survival. However, uncertainty surrounds the impact of population-wide screening. Testicular self-examination (TSE) is a simple detection method but there is a gap in current practices that needs to be assessed. Our goal was to assess the perceptions and knowledge of male subjects in the general population (MP) and general practitioners (GPs) regarding TSE for TC., Methods: Two distinct surveys evaluating knowledge and perceptions of TSE for TC were administered to GPs and MP, aged 15‒45-years. Factors that could favour the realisation of TSE or improve the knowledge of TC were evaluated by multivariable logistic regression., Results: Overall, 1048 GPs (mean (SD) age: 35.1 ± 10.3 years) and 1032 MP (mean (SD) age: 27 ± 8.2 years) answered the survey. Among the GPs, only 93 (8.9%) performed scrotal examination for TC screening. Although the majority (n = 993, 94.8%) were aware of the age of onset of TC, most (n = 768, 73.3%) did not know the overall survival rate from TC. GPs familiar with the guidelines were more likely to explain TSE to their patients (OR = 2.5 [95% CI 1.5‒4.1]; p < 0.01). Among the MP, 800 (77.5%) admitted that they did not know how to perform TSE and 486 (47.1%) did not know the main symptoms associated with TC. MP who had already undergone TC screening were more likely to be familiar with the main symptoms (OR = 2.1 [95% CI 1.6‒2.7]; p < 0.001) and MP who knew someone with TC or who had already undergone TC screening were more likely to be aware of the correct prevalence of TC (OR = 1.9 [95% CI 1.3‒2.7], p < 0.01; and OR = 1.6 [95% CI 1.2‒2.1], p < 0.01; respectively)., Conclusion: The knowledge of both GPs and MP regarding TC could be improved. TSE screening and knowing someone close with TC improved the awareness of our subjects., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Purpose: To compare the oncological and perioperative outcomes of robot-assisted partial nephrectomy (RPN) and percutaneous thermal ablation (PTA) for treatment of T1 renal cell cancer (RCC) in patients older than 75 years., Materials and Methods: Retrospective national multicenter study included all patients older than 75 years treated for a T1 RCC by RPN or PTA between January 2010 and January 2021. Patients' characteristics, tumor data, and perioperative and oncological outcomes were compared., Results: A total of 205 patients for 209 procedures (143 RPN and 66 PTA) were included. In the PTA group, patients were older (80.4 ± 3.7 vs. 79 ± 3.7 years (p = 0.01)); frailer (ASA score (2.43 ± 0.6 vs. 2.17 ± 0.6 (p < 0.01)); and more frequently had a history of kidney surgery (16.7% [11/66] vs. 5.6% [8/143] (p = 0.01)) than in the RPN group. Tumors were larger in the RPN group (2.7 ± 0.7 vs. 3.2 ± 0.9 cm (p < 0.01)). Operation time, length of hospital stay, and increase of creatinine serum level were higher in RPN (respectively 92.1 ± 42.7 vs. 150.7 ± 61.3 min (p < 0.01); 1.7 ± 1.4 vs. 4.2 ± 3.4 days (p < 0.01); 1.9 ± 19.3% vs. 10.1 ± 23.7 (p = 0.03)). Disease-free survival and time to progression were similar (respectively, HR 2.2; 95% CI 0.88-5.5; p = 0.09; HR 2.1; 95% CI 0.86-5.2; p = 0.1). Overall survival was shorter for PTA that disappeared after Cox adjusting model (HR 3.3; 95% CI 0.87-12.72; p = 0.08)., Conclusion: Similar oncological outcomes are observed after PTA and RPN for T1 RCC in elderly patients., Clinical Relevance Statement: Robot-assisted partial nephrectomy and percutaneous thermal ablation have similar oncological outcomes for T1a kidney cancer in patients over 75 years; however, operative time, decrease in renal function, and length of hospital stay were lower with ablation., Key Points: • After adjusting model for age and ASA score, similar oncological outcomes are observed after percutaneous thermal ablation and robot-assisted partial nephrectomy for T1 renal cell cancer in elderly patients. • Operation time, length of hospital stay, and increase of creatinine serum level were higher in the robot-assisted partial nephrectomy group., (© 2023.

Background: The SPARE Nephrometry Score (NS) is described as easier to implement than the RENAL and PADUA NSs, currently more widely used. Our objective was to compare the accuracy of SPARE NS in predicting renal function outcomes following RAPN., Methods: A multicentric retrospective study was conducted using French kidney cancer network (UroCCR, NCT03293563) database. All patients included had RAPN for cT1 renal tumors between May 2010 and March 2021. SPARE was compared to RENAL, PADUA and Tumor Size to predict postoperative acute kidney injury (AKI), chronic kidney disease (CKD) upstaging, de novo CKD at 3-6 months follow-up and Trifecta failure. The ability of the different NSs and tumor size to predict renal function outcomes was evaluated using uni- and multivariate logistic regression models., Results: According to our study criteria, 1171 patients were included. Mean preoperative tumor size and estimated glomerular filtration rate (eGFR) were 3.4±1.4 cm and 85.8 mL/min/1.73 m 2 . In total, 266 (22.7%), 87 (7.4%), 94 (8%), and 624 (53.3%) patients had AKI, de novo CKD, CKD upstaging, and Trifecta failure, respectively. In multivariate analysis, all three NSs and tumor size were independent predictors of AKI, CKD de novo, CKD upgrade and Trifecta failure. There was no significant difference between all three NS and tumor sizes in predicting renal function outcomes., Conclusions: SPARE Score seems to be a valid alternative to predict renal function outcomes after RAPN. Nevertheless, in our study, tumor size was as accurate as NSs in predicting postoperative outcomes and, therefore, seems to be the logical choice for surgical decisions.

Objectives: To assess the impact of pathological upstaging from clinically localized to locally advanced pT3a on survival in patients with renal cell carcinoma (RCC), as well as the oncological safety of various surgical approaches in this setting, and to develop a machine-learning-based, contemporary, clinically relevant model for individual preoperative prediction of pT3a upstaging., Materials and Methods: Clinical data from patients treated with either partial nephrectomy (PN) or radical nephrectomy (RN) for cT1/cT2a RCC from 2000 to 2019, included in the French multi-institutional kidney cancer database UroCCR, were retrospectively analysed. Seven machine-learning algorithms were applied to the cohort after a training/testing split to develop a predictive model for upstaging to pT3a. Survival curves for disease-free survival (DFS) and overall survival (OS) rates were compared between PN and RN after G-computation for pT3a tumours., Results: A total of 4395 patients were included, among whom 667 patients (15%, 337 PN and 330 RN) had a pT3a-upstaged RCC. The UroCCR-15 predictive model presented an area under the receiver-operating characteristic curve of 0.77. Survival analysis after adjustment for confounders showed no difference in DFS or OS for PN vs RN in pT3a tumours (DFS: hazard ratio [HR] 1.08, P = 0.7; OS: HR 1.03, P > 0.9)., Conclusions: Our study shows that machine-learning technology can play a useful role in the evaluation and prognosis of upstaged RCC. In the context of incidental upstaging, PN does not compromise oncological outcomes, even for large tumour sizes., (© 2023 The Authors.

Purpose: The management of solitary kidney tumors is a surgical challenge, requiring irreproachable results on both oncological and functional outcomes. The goal of our study was to compare the perioperative results of robotic-assisted partial nephrectomy (RAPN) to open surgery in this indication., Methods: We led a multicentric study based on the prospectively maintained French national database UroCCR. Patients who underwent partial nephrectomy on a solitary kidney between 1988 and 2020 were included. Clinical and pathological data were retrospectively analyzed. The main outcome of the study was the analysis of the variation of the estimated glomerular filtration rate (eGFR) calculated according to MDRD at 3, 6, 12, and 24 months depending on the chosen surgical approach. The secondary outcomes were the comparison of Trifecta success, perioperative complications, and length of hospital stay., Results: In total, 150 patients were included; 68 (45%) in the RAPN group and 82 (55%) in the open surgery group. The two groups were comparable for all data. The variation of eGFR at 3, 6, 12, or 24 months was comparable without any significant difference between the 2 groups (p = 0.45). Trifecta was achieved in 40% of the patients in the RAPN group and 33% in the open group (p = 0.42). A significant difference was observed for the length of stay, 5 days for the robot group versus 9 days for the open surgery group (p < 0.0001)., Conclusion: In our study, the surgical approach did not modify functional results and we noted a significant decrease in hospital stay and complications in the RAPN group. RAPN is a safe and efficient method for management of kidney tumors in solitary kidneys., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: The prognostic impact of renal cell carcinoma (RCC) morphotype remains unclear in patients who undergo partial nephrectomy (PN). Our objective was to determine the risk factors for recurrence after PN, including RCC morphotype., Methods: Patients with RCC who had undergone PN were extracted from the prospective, national French database, UroCCR. Patients with genetic predisposition, bilateral or multiple tumours, and those who had undergone secondary totalization were excluded. Primary endpoint was 5-year, recurrence-free survival (RFS), and secondary endpoint was overall survival (OS). Risk factors for recurrence were assessed by multivariable Cox regression analysis., Results: Overall, 2,767 patients were included (70% male; median age: 61 years [interquartile range (IQR) 51-69]). Most (71.5%) of the PN procedures were robot-assisted. Overall, 2,573 (93.0%) patients were recurrence free, and 74 died (2.7%). Five-year RFS was 84.9% (IQR 82.4-87.4). A significant difference in RFS was observed between RCC morphotypes (p < 0.001). Surgical margins (hazard ratio [HR] = 2.0 [95% confidence interval (CI): 1.3-3.2], p < 0.01), pT stage >1 (HR = 2.6 [95% CI: 1.8-3.7], p < 0.01]) and Fuhrmann grade >2 (HR = 1.9 [95% CI: 1.4-2.6], p < 0.001) were risk factors for recurrence, whereas chromophobe subtype was a protective factor (HR = 0.08 [95% CI: 0.01-0.6], p = 0.02). Five-year OS was 94.0% [92.4-95.7], and there were no significant differences between RCC subgroups (p = 0.06). The main study limitation was its design (multicentre national database), which may be responsible for declarative bias., Conclusions: Chromophobe morphotype was significantly associated with better RFS in RCC patients who underwent PN. Conversely, pT stage, Fuhrman group and positive surgical margins were risk factors for recurrence., (© 2022. Society of Surgical Oncology.)

Renal arteriovenous malformation is a primarily congenital renal vascular abnormality. It is usually diagnosed incidentally on imaging, and the most common subtype is 'cirsoid', consisting of multiple, enlarged arterial feeders interconnecting with draining veins. We present a 74-year-old woman with an incidental finding of what was at first considered a hypervascularised kidney tumour but turned out to be a left intrarenal arteriovenous malformation associated with a left renal vein thrombosis. Selective endovascular embolisation was performed. The cause-consequence relationship between the arteriovenous malformation and the thrombosis is unique. To our knowledge, no such case has ever been reported., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021. No commercial re-use.

Objectives: To report the outcomes and feasibility of active surveillance (AS) of biopsy-proven renal oncocytomas., Methods: Multicentric retrospective study (2010-2016) in 6 academic centers that included patients with biopsy-proven renal oncocytomas who were allocated to AS (imperative or elective indication) with a follow-up ≥1 year. Imaging was performed at least once a year, by CT-scan or ultrasound or MRI. Conversion to active treatment (surgical excision or ablative treatment) was at the discretion of the urologist. The primary endpoint was renal tumor growth (cm/year). Secondary outcomes included accuracy of biopsy, incidence, and reason to change AS to active treatment., Results: Eighty-nine patients were included: Median age 67 years (26-89) and median tumor size 26 mm [15-90] on diagnosis. During a mean follow-up of 43 months'' (median 36 [12-180]), mean tumor growth was 0.24 cm/year. No predictive factors (demographical, radiological or histologic) of tumor growth could be identified. Conversion from AS to active treatment occurred in 24 patients (27%) (13 surgical excisions, 11 ablative procedures), in a median time of 45 (12-76) months'' after diagnosis. Tumor growth was the main indication to convert AS to active treatment (58%) with 8% of the patients opting to discontinue AS. No patient had metastatic progression nor disease-specific death. The correlation between biopsy and surgical specimen was 92%., Conclusion: Active surveillance for biopsy-proven renal oncocytomas was oncologically safe and patient adherence was high. No predictive factor for tumor growth could be identified but the tumor growth rate was low, and biopsy efficacy was high., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background: The current pathological tumour-node-metastasis (pTNM) classification for upper tract urothelial carcinoma (UTUC) does not include any risk stratification of pT3 renal pelvicalyceal tumours., Objective: To assess the prognostic impact of pT3 subclassification in a multicentre cohort of patients with UTUC of the renal pelvicalyceal system undergoing radical nephroureterectomy (RNU)., Design, Setting, and Participants: Data from all consecutive patients treated with RNU for pT3 renal pelvicalyceal UTUC at 14 French centres from 1995 to 2013 were reviewed retrospectively., Intervention: A central pathology review (CPR) was used to stratify pT3 patients into those with infiltration of the renal parenchyma on a microscopic level (pT3a) versus those with infiltration of the renal parenchyma visible on gross inspection of the resection specimen and/or invasion of peripelvic fat (pT3b)., Outcome Measurements and Statistical Analysis: Inverse probability weighting (IPW)-adjusted Cox regression analyses were used to compare recurrence-free survival (RFS) and cancer-specific survival (CSS) between pT3a and pT3b patients., Results and Limitations: Overall, 202 patients were included and further stratified into pT3a (n = 98; 48.5%) and pT3b (n = 104; 51.5%) subgroups. Median time to follow-up in the weighted population was 68 (interquartile range, 50-95) mo. In IPW-adjusted Cox regression analyses, pT3b versus pT3a substage was associated with a significant adverse effect on RFS (hazard ratio [HR] = 2.02; 95% confidence interval [CI] = [1.36-3.01]; p < 0.001) and CSS (HR = 1.84; 95% CI = [1.20-2.82]; p = 0.005). The study is limited by its retrospective design., Conclusions: Using IPW-adjusted analyses after the CPR, we observed that RNU patients with pT3b renal pelvicalyceal UTUC had adverse prognosis as compared with those with pT3a disease. As such, this subclassification could help refine the current pTNM system for UTUC., Patient Summary: In this report, we looked at the prognostic interest of stratifying patients with pT3 renal pelvicalyceal upper tract urothelial carcinoma based on the extent of local invasion. We found that those with extensive infiltration (pT3b) had adverse prognosis as compared with those with limited infiltration (pT3a). This information could be provided on pathology reports to further guide clinical decision making., (Copyright © 2020 European Association of Urology. Published by Elsevier B.V.

Premature ejaculation (PE) is the most common self-reported male sexual disorder estimated to occur in approximately 5% of men in the general community. Penile hypersensitivity is thought to be an etiologic factor of lifelong PE. The role of glans penis augmentation using injectable hyaluronic acid (HA) for the treatment of PE is debatable and remains to be confirmed. The creation of a barrier at the level of the glans, by the bulking agent blocking accessibility and inhibiting the tactile stimuli to reach the dorsal nerve of the penis (branch of the pudendal nerve) receptors, is the theory behind the effectiveness of HA in the field of PE. We reviewed the literature using PubMed and searched for the following keywords: premature ejaculation, glans penis and HA, over the last 20 years. Five studies were found. These studies showed that HA injection could significantly increase IELT (2.43- to 4.46-fold), and this increase could persist for long term (up to 5 years). No serious adverse reactions were reported besides transient discoloration and swelling of the glans that recovered to normal within 2 weeks. Many techniques were discussed, their effectiveness remains to be proved. However, proper patient selection and mastering the esthetics of the technique, by adequate surgical training, is necessary in order to achieve the optimal results., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/tau-20-1026).

Background and Objectives: To evaluate the pathological features and recurrence of incidental testis tumours treated by partial orchiectomy in a population of infertile men., Methods: We retrospectively pooled, from four andrology referral centres, 32 patients diagnosed with testis mass during regular infertility workup. Patients included had an impaired sperm analysis and testis sparing surgery was performed to prevent secondary azoospermia or androgen therapy., Results: Mean age was 36 (IQR, 32 to 37). The mean largest tumoral diameter was 8.5 mm (IQR, 5 to 10). A total of 25% (8 of 32) of patients had a malignant tumour (seminoma, 7 of 32, 22%; teratoma, 1 of 32, 3%) and 75% (24 of 32) had a benign lesion (Leydig cell tumour, 23 of 32, 72%; scar tissue, 1 of 32, 3%). Malignant tumours were then managed by total orchiectomy (six of eight) or by radiotherapy (two of eight). With a mean follow up of 26 months (IQR, 8 to 32), one patient (3%) had an homolateral recurrence, which was a Leydig cell tumour. Not a single patient developed metastasis., Conclusion: Seventy-five per cent of the tumours discovered during infertility management were of a benign pathology. A conservative approach could be proposed initially to avoid unnecessary orchiectomies. Orchiectomy and radiotherapy could be discussed as salvage therapies for malignant lesions., (© 2018 Wiley Periodicals, Inc.)

Background: Help in management of non-palpable testicular tumors. French Urologic Association Genital cancer committee's Edit., Objectives: To review their characterization at imaging findings of non-palpable testicular tumors., Documentary Sources: Literature review (PubMed, Medline) of urological and radiological studies dealing with testicular tumors using keywords: non-palpable/incidental testicular tumors; color Doppler ultrasound; US elastography; magnetic resonance imaging; contrast enhanced sonography; partial surgery., Results: Color Doppler is the basic exam. The size, the presence of microlithts/microlithiasis/macrocalcifications, the vascular architecture are major semiological findings to suggest the benign or the malignant nature of the lesion. Other techniques like multiparametric MRI, contrast-enhanced sonography, sonographic elastography are still in evaluation. The frequency of benign tumors such as Leydig cell tumors lead to preservation management, through improved characterization, monitoring or tumorectomy., Limits: Non-randomized study - a very few prospective studies., Conclusion: The era of total orchiectomy for any uncertain testicular lesion is over. We try the challenge of characterization, and define management's algorithms based on the suspected nature of the tumors., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)

Background and Objectives: To identify predictive preoperative factors of the presence of teratoma in retroperitoneal lymph node dissection specimens., Methods: We performed a 20 years multicenter retrospective analysis of all patients who underwent retroperitoneal lymph node dissection for residual masses after chemotherapy (PC-RPLND). Patients had undergone PC-RPLND after chemotherapy for advanced testicular cancer. The histologic components of the primary tumor were compared with those of the residual masses using logistic regression., Results: A total of 469 NSGCT patients underwent PC-RPLND (complete data available for 211). By PC-RPLND, necrosis was found in 84 cases, teratoma in 102 cases, and viable tumor in 25 cases. The univariate and multivariate analyses showed that teratoma (P = 0.001 and P = 0.002, respectively) and yolk sac tumor (P = 0.009 and P = 0.035, respectively) in orchiectomy specimens were statistically significant predictors of the presence of teratoma in retroperitoneal lymph nodes., Conclusions: PC-RPLND is the standard treatment for any supracentimetric residual lesion. This procedure is associated with a high morbidity, and almost half patients are overtreated. The presence of teratoma and yolk sac tumor in the orchiectomy specimen were independent significant predictors of teratoma in retroperitoneal masses. J. Surg.

Introduction: The aim of this work is to establish guidelines proposed by the external genital organ group of the CCAFU for the diagnosis, treatment and follow-up of penile cancer., Material and Methods: The multidisciplinary working party studied 2013 guidelines exhaustively reviewed the literature, and evaluated references and their level of proof in order to attribute grades of recommandation., Results: The most common histological type is squamous cell carcinoma. Clinical examination of the penis is usually sufficient to access local extension. It can be completed by MRI to assess deeper extension. Physical examination of both groins must evaluate inguinal regional lymph nodes involvement. In the presence of palpable lymph nodes, abdomen and pelvis computed tomography and 18 F-FDG PET-CT are recommended. Sentinel lymph node biopsy is recommended in the case of penile cancer with high risk of lymph node extension with no palpable lymph nodes. Treatment of the primary tumour is usually surgical. It must be as conservative as possible while ensuring negative surgical margins. Brachytherapy or local treatment can be proposed in some cases. Bilateral inguinal lymph node areas must be systematically treated. Inguinal lymphadenectomy alone has a curative role in patients with metastatic invasion of a single node (stage pN1). In the case of more extensive lymph node involvement, multimodal management combining chemotherapy, surgery, and possibly radiotherapy has to be considered., Conclusions: The treatment of penile cancer is usually surgical possibly in combination with chemotherapy in the presence of lymph node extension. The main prognostic factor is lymph node involvement, requiring appropriate management at the time of diagnosis.x © 2016 Elsevier Masson SAS. All rights reserved., (© 2016 Elsevier Masson SAS.

Introduction: The purpose of the oncologic comitee of the french association of urology was to establish guidelines proposed by the external genital organ group, for the diagnosis, treatment and follow-up of the germ cell tumours of the testis., Material and Methods: The multidisciplinary working group studied 2013 guidelines, exhaustively reviewed the literature, and evaluated references and their level of proof in order to attribute grades of recommandation., Results: The initial workup of testicular cancer is based on clinical, laboratory (AFP, total hCG, LDH) and imaging assessment (scrotal ultrasound and chest, abdomen and pelvis computed tomography). Inguinal orchiectomy is the first line treatment allowing characterization of the histological type, local staging and identification of risk factors for micrometastases. The management of stage I tumors is based on surveillance or on a risk-adapted approach with explaining to the patient the benefits/disadvantages of active treatment or watchful waiting as a function of the risk of relapse. Treatment options for stage I seminomas comprise: surveillance, chemotherapy (1cycle of carboplatin) or para-aortic radiotherapy. Treatment options for stage I nonseminomatous germ cell tumours comprise: surveillance, chemotherapy (1cycle of BEP) or staging retroperitoneal lymphadenectomy. The management of metastatic tumors essentially comprises chemotherapy with 3, 4 cycles of BEP or dose-dense chemotherapy according to the IGCCCG. Radiotherapy may be indicated in seminomas with lymph node metastasis < 3cm. Review 3 to 4 weeks postchemotherapy is essentially based on tumor marker assays and chest, abdomen and pelvis computed tomography. Surgical retroperitoneal lymph node dissection is indicated for all residual NSGCT masses > 1cm and for persistent residual seminoma masses > 3cm with 18F- FDG PET- CT uptake., Conclusions: Good Germ cell tumors specific survival rates (99% CSI, 85% CSII, III) are based on precise initial staging, adapted and strictly defined treatment and close surveillance. © 2016 Elsevier Masson SAS.

Introduction: The purpose of this article was established by the external genitalia group CCAFU recommandations for diagnosis, treatment and monitoring of retroperitoneal sarcomas, intended for urologists., Material and Methods: The multidisciplinary working group has updated the 2013 guidelines, based on an exhaustive review of the literature on PubMed, valued references, level of evidence, to assign grades of recommendation., Results: From a clinical suspicion evoking a RPS, computed tomography thoraco abdominal and pelvic is the gold standard. MRI is useful for surgical planning. Before the biopsy confirmation, the inclusion of the file in the French sarcoma pathology reference network should be the rule. The biopsy under scanner performed by retroperitoneal approach is recommended and should be achieve before any therapeutic management of a suspicious retroperitoneal solid mass. Treatment is primarily surgical with the main objective resection in healthy margins (R0) obtained by a technically challenging compartmental resection surgery. Instead of radiation therapy and chemotherapy within a multimodal treatment (neo adjuvant or adjuvant) is discussed based on the evolving risks and opportunities excision. The relapse rate is related to tumor grade and surgical margin. The final prognosis is closely related to the quality of initial management and the volume of cases handled by the center., Conclusion: The RPS has a poor prognosis. The quality of the initial management directly impacts the disease-free survival and overall survival. The multidisciplinary management coordinated within a referent care network of sarcoma pathology is an imperative necessity. © 2016 Elsevier Masson SAS.

Introduction: The composition of a French Forward Surgical Team (FST) has remained constant since its creation in the early 1950s: 12 personnel, including a general and an orthopaedic surgeon. The training of military surgeons, however, has had to evolve to adapt to the growing complexities of modern warfare injuries in the context of increasing subspecialisation within surgery. The Advanced Course for Deployment Surgery (ACDS)-called Cours Avancé de Chirurgie en Mission Extérieure (CACHIRMEX)-has been designed to extend, reinforce and adapt the surgical skill set of the FST that will be deployed., Methods: Created in 2007 by the French Military Health Service Academy (Ecole du Val-de-Grâce), this annual course is composed of five modules. The surgical knowledge and skills necessary to manage complex military trauma and give medical support to populations during deployment are provided through a combination of didactic lectures, deployment experience reports and hands-on workshops., Results: The course is now a compulsory component of initial surgical training for junior military surgeons and part of the Continuous Medical Education programme for senior military surgeons. From 2012, the standardised content of the ACDS paved the way for the development of two more team-training courses: the FST and the Special Operation Surgical Team training. The content of this French military original war surgery course is described, emphasising its practical implications and future prospects., Conclusion: The military surgical training needs to be regularly assessed to deliver the best quality of care in an context of evolving modern warfare casualties., (Published by the BMJ Publishing Group Limited.

Objectives: To determine if the epidemiology of testis cancer in military service has followed worldwide trends and if the end of conscription in 2000 in France marked an epidemiologic turn., Methods: All of the patients who had an orchiectomy for a testis germ tumor from January 1990 to January 2011 were studied. The patients were divided into two groups: orchiectomy before 2000 and after 2000., Results: 289 patients were included, with a mean age of 30.8. The mean age at diagnosis increased significantly as well as the proportion of stage 1 seminomas, whereas stage 1 nonseminomatous germ cell tumors (NSGCT) slightly decreased. For stage 1 seminomas, there was an increase in the surveillance (10% vs. 31%) and in the number of chemotherapies (19% vs. 22%); for stage 1 NSGCT, surveillance also increased (53% vs. 64%). The specific 5-year survival was 98.3%., Conclusions: We noted an increase in the number of stage 1 seminomas, the surveillance of located germ tumors, and an excellent survival rate. However, the population was younger with regard to national data, and the number of stage 1 NSGCT decreased in favor of advanced metastatic tumors., (Reprint & Copyright © 2015 Association of Military Surgeons of the U.S.)

Introduction: The aims of this study were as follows: first to quantify and review the types of surgical procedures performed by military surgeons assigned to a Forward Surgical Team (FST) providing medical support to the population (MSP) in the Ivory Coast (IC), and second to analyze how this MSP was achieved., Methods: Between 2002 and 2012, all of the local nationals operated on by the different FSTs deployed in the IC were included in the study. The surgical activity was analyzed and divided into surgical specialties, war wounds, nonwar emergency trauma, nontrauma emergencies, and elective surgery. Demographics, circumstances of health care management, wounded organs, and types of surgical procedures were described., Results: Over this period, surgeons operated on 2,315 patients and performed 2,556 procedures. Elective surgery accounted for 78.7% of the surgical activity, nontrauma emergencies accounted for 12.7%, nonwar emergency trauma accounted for 8%, and war wounds accounted for 0.6%. The main surgical activities were visceral (43.8%) and orthopedic (including soft tissues) surgeries (38.5%)., Conclusion: The FSTs contributed widely to MSP in the IC. This MSP required limited resources, standardization of the procedures and specific skills beyond the original surgical specialties of military surgeons to fulfill the needs of the local population., (Reprint & Copyright © 2015 Association of Military Surgeons of the U.S.)

Objectives: To evaluate the quality of life of the holders of a ureteral double J stent (US) using the USSQ questionnaire (Ureteral Stent Symptom Questionnaire), validated in French in 2010., Methods: Between January 2009 and December 2011, 249 patients underwent flexible ureteroscopy for urolithiais in our service. Among them, 160 received a US in perioperative, and they were sent self-questionnaire USSQ-FR retrospectively. The questionnaire includes 38 questions, concerning the perioperative period with US, and 4 weeks after its removal, grouped into 6 sections: urinary symptoms, pain, general health, professional resounding, sexual resounding, and other problems. A subgroup analysis was performed, comparing US used in emergency and planned US, active patients or retired, male or female. Statistical analysis used the Chi(2) test for paired data, the Fisher exact test and the Kruskal Wallis test., Results: Of the 157 questionnaires sent (two patients who died, one mentally retarded), we obtained 80 responses. Quality of life appears to be significantly altered in all areas explored by the questionnaire. Urinary symptoms: 26.9 versus 19.9 score (P<0.0001), pain: 16.1 versus 10.7 (P=0.003), general health: 13.9 versus 9.1 (P<0.0001), professional practice: 6.1 versus 3.6 (P=0.0002), female: 3.3 versus 1.8 (P=0.001). There was no significant difference if the US was placed in emergency or programmatically, if patients were professionally active or retired. In addition, women had a significantly impaired quality of life compared to men for urinary symptoms, general health and professional practice., Conclusion: US are responsible for a significant impairment of quality of life for patients. The validated, self-administered, USSQ-FR questionnaire is a reliable tool for this evaluation., Level of Evidence: 5., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

Urothelial bladder cancer (UBC) is rare in young patients and as a result little information as to tumor type and clinical course are available. We present clinicopathological data of a large series of patients less than 40 years with bladder carcinoma. We included in this retrospective study covering the period from 1992 to 2013 patients less than 40 years with a first diagnosis of bladder cancer. Lesions were classified according to the WHO 2004 classification by uropathologists of ten centers. Stage, grade, multifocality, smoking habits, recurrence, and survival were studied. The cohort comprised of 152 patients, 113 males and 39 females with a mean age of 33.2 years. The large majority of the patients (142) was diagnosed with an urothelial carcinoma, the ten others with various histopathological diagnoses. In the age group less than 30 years old, 40.3 % of the cases concerned a papillary urothelial neoplasia of low malignant potential (PUNLMP). In the age group over 30 years, the proportion of PUNLMP decreased to 27.2 %. Only 5.6 % of the UBC was associated with carcinoma in situ. In 14.1 %, a high grade muscle invasive UC was found; 7.0 % had lymph node and 4.9 % distant metastasis at time of presentation. Four patients presented with a history of schistosomiasis; all had an infiltrating carcinoma. After initial resection, 36 patients relapsed, 17 % as PUNLMP, 53 % as pTa low grade, and 30 % as pTa-pT2 high grade UC. During follow-up, 6 % of the patients died. PUNLMP is the most frequent entity in this patient group. It is important that the PUNLMP entity is maintained in future classification systems.

We report the case of an 83 years old man supported for painless indurated and nodular lesion of the left testicle. Histological analysis identified a primary cutaneous melanoma metastasis although it has never been found on physical examination. The discovery of a testicular mass should suggest first a germ cell tumor, despite in some populations (age over 60 years), other diagnosis are more frequent, including metastasis. Due to rapid disease progression and high mortality rate within a short interval, a complete staging looking for other secondary locations must be done and a multidisciplinary care and palliative involvement must also be initiated in the context of metastatic melanoma., (Copyright © 2015.

A 45-year-old man with a left testis tumor with a 25 mm para-aortic lymph node swelling, multiple bilateral pulmonary metastases, bilateral pulmonary embolism, and inferior vena cava (IVC) thrombus underwent a radical orchidectomy in our institution. The thrombus extended from the left gonadal vein to the left renal vein to the IVC. The fluorine-18 fluorodeoxyglucose (f-FDG) positron emission tomography (PET) computerized tomography (CT) demonstrated a hypermetabolic focus in the retroperitoneum and in the IVC thrombus. Before orchidectomy only lactate dehydrogenase (LDH) was high but all the serum tumor markers increased postoperatively. The tumor was staged pT1N2M1aS1, which was an intermediate prognosis, based on the International Germ Cell Cancer Collaborative Group consensus (IGCCCG). After 4 courses of bleomycin, etoposide, and cisplatin (BEP) chemotherapy the patient's tumor markers normalized and the thrombus disappeared. There was only one residual retroperitoneal lymph node M1. Retroperitoneal lymph node dissection was performed. The pathological examination revealed only necrotic tissues. The patient has been disease-free since surgery.

Objective: To review long-term oncological and functional outcomes of testicular-sparing surgery (TSS) in men presenting with bilateral or monorchide testicular tumours at one of five reference centres for testicular neoplasm and infertility., Patients and Methods: We review 25 cases of bilateral synchrone and metachrone testicular tumours treated in five academic centres between 1984 and 2013. Clinical, biological, ultrasonography and pathological tumour findings, overall survival (OS) times, local or metastatic recurrence, pre- and postoperative hormonal profile, paternity and the need for androgen substitution were assessed., Results: Eleven patients with a bilateral synchrone tumour and 14 patients with a testicular tumour on a solitary testicle underwent a tumorectomy. The mean (sem) patient age was 31.9 (1.04) years, total testosterone level was 4.5 (0.57) ng.mL and tumour size was 11.66 (1.49) mm. Tumour types were as follows: 11 seminoma, nine non-seminomatous or mixed germ cell tumours, four Leydig tumours, and one hamartoma. Frozen-section examination was performed in 14 patients, and matched the final pathological analysis in 11 patients. There was an OS rate of 100% and three patients (12%) presented with a local recurrence after a mean follow-up of 42.7 months. Radical orchiectomy was performed for six patients. No patient with a preserved testicle required androgen therapy; the mean postoperative total testosterone level was 4.0 ng/mL. No patient remained fertile after radiation therapy., Conclusions: TSS for bilateral testicular tumour is safe and effective in selected patients, and should be considered to avoid definitive androgen therapy. Adjuvant radiotherapy remains poorly described in the literature, leading to adjuvant treatment heterogeneity for testicular tumours., (© 2013 The Authors.

Introduction: The objective of this article was to focus on the pathological, clinical and therapeutic aspects of the different forms of testicular teratoma in adults., Material and Methods: The multidisciplinary working group has conducted a literature search on Pubmed with keywords: adult teratoma; malignant transformation; growing teratoma; chemotherapy; surgery with focus on the different forms of adult testicular teratoma., Results: Teratomas of the adults are malignant and subdivided into localized and metastatic forms that may be distinguished under exclusive teratoma form, growing teratoma or teratoma with malignant transformation. The management is based on an enlarged surgical excision (testis and metastasis) with, in metastatic forms, a chemotherapy adjusted with histology. Extended follow-up beyond 10 years is necessary because of the risk of late relapse., Conclusions: Testicular teratoma is a rare tumor, which is considered malignant with a potential of metastasis. The treatment is based mainly on surgical management., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)
