ABSTRACT

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.

ABSTRACT

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. Stabl is available at https://github.com/gregbellan/Stabl .

ABSTRACT

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.

ABSTRACT

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 m2. 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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Laser enucleation of the prostate represents the endoscopic response to open simple prostatectomy for the treatment of large benign prostatic hyperplasia (BPH) and an advanced technique for prostate surgery. To date, no more than 20 cases of giant prostatic hyperplasia (GPH) have been reported in the literature. We report a successful holmium laser enucleation of a 696 cc prostate in a 78 year-old patient on anticoagulation that was embolized prior to the intervention, urinary catheter was removed on the first day post-operatively and the patient was discharged home on the second day. This is considered the largest prostate treated endoscopically.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Forniceal rupture secondary to acute ureteral obstruction is relatively common. However, spontaneous ureteral rupture is less frequently encountered. Most reported cases were stone related, localized at the ureteropelvic junction and managed in a minimally invasive manner. We present a case of stone induced ureteral rupture below the UPJ, with bacterial and fungal superinfections, that failed conservative management and lead eventually to nephrectomy. No such scenario has ever been reported in the literature. As rupture of the ureter can cause serious complications, including urinoma, sepsis and sometimes kidney loss, prompt recognition, treatment and follow-up of the condition is therefore necessary.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.
