What happens to orgasmic function after surgical benign prostate hypertrophy (BPH) treatments?

INTRODUCTION: The increasing number of subjects with benign prostate obstruction (BPO) has become a worldwide concern. The sexual problem after benign prostate enlargement (BPE) surgery that has received the most attention in the literature is ejaculation disorder. However, there appears to be a change in orgasmic sensation independent of ejaculation retention. The objective of our study is to explore the influence of BPE surgery on orgasmic function. METHODS: We evaluated the prospective, multicenter clinical data of 104 patients undergoing BPE surgery who reported maintaining sexual activity from January 2016 to November 2020. The endpoint of this study was to decipher the percentage of patients with an orgasm disorder as assessed by the difference between pre-and-postoperative question 10 of the IIEF 15 questionnaire. RESULTS: Orgasm function was stable, improved, and degraded in 34% (n=35), 30% (n=31), and 36% (n=38) respectively. A deterioration in orgasm was statistically significant in men who maintained quality ejaculation with retained force preoperatively and a high IIEF15 scale values preoperative of orgasmic function, overall and intercourse patient satisfaction. CONCLUSION: To enable the patient to maintain a satisfying and healthy sex life after any BPE surgery, urologist physicians should know the prevalence of orgasmic side effects after surgical treatment to provide appropriate counseling to patients. LEVEL OF EVIDENCE: Grade 4.

Is there a best timing for benign prostatic hyperplasia surgery?

INTRODUCTION: Treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH) has shifted over the last decades, with medical therapy becoming the primary treatment modality while surgery is being reserved mostly to patients who are not responding to medical treatment or presenting with complications from BPH. Here, we aim to to discuss the optimal timing of surgical management of LUTS/BPH. MATERIALS AND METHODS: A literature search was conducted on Pub-Med/MEDLINE database to identify reports published from January 1990 until January 2022 by combining the following MeSH terms: "Lower Urinary Tract Symptoms"; "Prostatic Hyperplasia"; "Prostatic Hyperplasia/therapy"; "Prostatic Hyperplasia/complications"; "Treatment Outcome"; "Time-to-Treatment". Evidence supporting or not early surgical treatment of BPH was examined and reported in a pros and cons form. RESULTS: The "pro early surgery" highlighted the superior efficacy and cost-effectiveness of surgery over medical treatment for BPH, as well as the possibility of worse postoperative outcomes for delayed surgical treatment. The "con early surgery" considered that medical therapy is efficient in well-selected patients and can avoid the serious risks inherent to surgical treatment of BPH including important sexual side effects. CONCLUSIONS: Clinical trials comparing the outcomes for prolonged medical therapy versus early surgical treatment could determine which approach is more beneficial in the long-term in context of the aging population. Until then, both approaches have their advantages and patients should be involved in the treatment decision.

[Surgical and pathological consequences of preoperative immunotherapy in onco-urology]. / Conséquences chirurgicales et anatomopathologiques de l'immunothérapie préopératoire en onco-urologie.

INTRODUCTION: Patients treated with immunotherapy might need surgical procedures in addition to the medical treatment. The main indications are cytoreductive nephrectomy, cystectomy (as part of clinical trials) and metastasis removal in some oligometastatic patients. This study aims to assess the feasibility of surgery for patients treated by immunotherapy and describes the histological modifications found in the pathological analysis. MATERIAL AND METHODS: We conducted a retrospective, monocentric study. We included all patients operated for a urologic cancer and previously treated with systemic immunotherapy between February 2018 and June 2022. We compared this population with a control group of patients treated with surgery without having previous immunotherapy. Patients were compared according to the cancer type, age and sex. We compared perioperative complications. We performed an analysis for evaluation of the peri-tumoral inflammatory infiltration. RESULTS: We included 50 patients in this study. The two groups were comparable in age (63.7 vs. 63.3years old, P=0.95) and sex (4 and 6 women in the first and second group). The peroperatory complication rate was comparable (20% vs. 16%, P=1). The mean bleeding volume was comparable (664 vs. 629mL; P=0.89). The postoperative complication rate (48% vs. 56%; P=0.78) and their grade (Clavien III-IV 8% vs. 24%; P=0.24) were comparable. The anatomopathological analysis described the same rate and intensity of peri-tumoral inflammatory infiltrate (96% vs. 96%; P=1). CONCLUSIONS: Preoperative immunotherapy does not appear to be associated with increased surgical difficulty and perioperative complications. Blind histological analysis of the surgical specimens did not reveal any specific features related to pre operative immunotherapy. LEVEL OF EVIDENCE: Grade 3 HAS.

Standardized technique for ejaculation preservation during prostatic endoscopic ablative surgery.

PURPOSE: Ejaculatory dysfunction is the most common side effect of benign prostatic hyperplasia surgery. Modified techniques have emerged with the aim of preserving antegrade ejaculation without compromising obstruction relief. None are standardized or validated. The PARTURP study is a randomized study investigating partial versus complete prostate resection. We conducted an investigator consensus meeting to define the ideal surgical technique to achieve both correct obstruction relief with ejaculation preservation. METHODS: An expert consensus meeting involving all investigators of the PARTURP study took place to define a common technique using the nominal group methodology. The objectives were to define the areas to be resected and the areas to be preserved; to define the criteria for proper obstruction relief; to define the criteria for proper ejaculation preservation. RESULTS: All investigators (n = 15) attended the consensus meeting, and agreement between all the participants was obtained. The anatomical landmarks to be preserved are located around the verumontanum and along the posterior part of the prostatic urethra. These structures must be preserved up to 2 cm from the verumontanum. The participants agreed on the need to preserve the urethral mucosa in all the areas to be preserved and to reach the enucleation plane in the areas of resection. CONCLUSIONS: Anatomical landmarks for ejaculation-sparing surgery have been defined by the investigators of the PARTURP randomized study. These landmarks will be used during the study, and the clinical outcomes of this ejaculation-sparing technique will be compared with complete resection with up to 3 years follow-up.

Long-Term Oncological and Functional Outcomes after Laparoscopic Partial Nephrectomy with Hyperselective Embolization of Tumor Vessels in a Hybrid Operating Room.

Laparoscopic partial nephrectomy (LPN) after hyperselective embolization of tumor vessels (HETV) in a hybrid operating room (HOR) that combines traditional surgical equipment with advanced imaging technology, is a non-clamping surgical approach to treat localized kidney tumors that has shown promising short-term results. The aim of this study was to evaluate the long-term oncological and functional outcomes of this procedure. All consecutive patients treated for a localized kidney tumor by LPN after HETV between May 2015 and October 2022 in a single academic institution were included in the study. Clinical, pathological and biological data were collected prospectively in the uroCCR database. We evaluated intraoperative data, postoperative complications, surgical margin and modification of renal function after surgery. We included 245 patients. The median tumor size was 3.2 (2.5-4.4) cm. The R.E.N.A.L. complexity was low, medium and high for 104 (43.5%), 109 (45.6%) and 26 (10.9%) patients, respectively. Median LPN time was 75 (65-100) min and median blood loss was 100 (50-300) mL. Surgical postoperative complications occurred in 56 (22.9%) patients with 17 (5.7%) major complications. The median Glomerular Function Rate variation at 6 months was -7.5 (-15--2) mL/min. Malignant tumors were present in 211 (86.1%) patients, and 12 (4.9%) patients had positive surgical margins. After a median follow-up of 27 (8-49) months, 20 (8.2%) patients had a tumor recurrence and 4 (1.6%) died from cancer. At 5 years, disease free survival, cancer specific survival and overall survival rates were 84%, 96.8% and 88.3%, respectively. Performing LPN after HETV in a HOR is a safe and efficient non-clamping approach to treat localized kidney tumors.

Nephrectomy for kidney tumour increases the risk of de novo arterial hypertension.

OBJECTIVE: To evaluate prospectively the effects of surgical excision of renal tumours on blood pressure (BP). PATIENTS AND METHODS: In a multicentre prospective study, we evaluated 200 patients who underwent nephrectomy for renal tumour between 2018 and 2020 at seven departments of the French Network for Kidney Cancer, the UroCCR. All patients had localized cancer without pre-existing hypertension (HTN). Blood pressure was measured the week before nephrectomy, and at 1 month and 6 months after nephrectomy, according to the recommendations for home BP monitoring. Plasma renin was measured 1 week before surgery and 6 months after surgery. The primary endpoint was the occurrence of de novo HTN. The secondary endpoint was clinically significant increase in BP at 6 months, defined by an increase in systolic and/or diastolic ambulatory BP ≥10 mmHg or requirement for medical antihypertensive treatment. RESULTS: Blood pressure and renin measurements were available for 182 (91%) and 136 patients (68%), respectively. We excluded from the analysis 18 patients who had undeclared HTN detected on preoperative measurements. At 6 months, 31 patients (19.2%) had de novo HTN and 43 patients (26.3%) had a significant increase in their BP. Type of surgery was not associated with an increased risk of HTN (21.7% partial nephrectomy [PN] vs 15.7% radical nephrectomy [RN]; P = 0.59). There was no difference between plasmatic renin levels before and after surgery (18.5 vs 16; P = 0.46). In multivariable analysis, age (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.02-1.12; P = 0.03) and body mass index (OR 1.14, 95% CI 1.03-1.26; P = 0.01) were the only predictors of de novo HTN. CONCLUSION: Surgical treatment of renal tumours is associated with significant changes in BP, with de novo HTN occurring in almost 20% of the patients. These changes are not impacted by the type of surgery (PN vs RN). Patients who are scheduled to undergo kidney cancer surgery should be informed of these findings and have their BP closely monitored after the operation.

Prospective Comparison of Thulium and Holmium Laser Lithotripsy for the Treatment of Upper Urinary Tract Lithiasis.

Background: Lithotripsy with holmium:yttrium-aluminum-garnet (Ho:YAG) laser is the current gold standard for treating stones of the upper urinary tract (UUT). The recently introduced thulium fiber laser (TFL) has the potential to be more efficient and as safe as Ho:YAG. Objective: To compare the performance and complications between Ho:YAG and TFL for UUT lithotripsy. Design setting and participants: This was a prospective single-center study of 182 patients treated between February 2021 and February 2022. In a consecutive approach, laser lithotripsy was performed via ureteroscopy with Ho:YAG for 5 mo, and then with TFL for 5 mo. Outcome measurements and statistical analysis: Our primary outcome was stone-free (SF) status at 3 mo after ureteroscopy with Ho:YAG versus TFL lithotripsy. Secondary outcomes were complication rates and results regarding the cumulative stone size. Patients were followed at 3 mo with abdominal imaging (ultrasound or computed tomography). Results and limitations: The study cohort comprised 76 patients treated with Ho:YAG laser and 100 patients treated with TFL. Cumulative stone size was significantly higher in the TFL than in the Ho:YAG group (20.4 vs 14.8 mm; p = 0.01). SF status was similar in both groups (68.4% vs 72%; p = 0.06). Complication rates were comparable. In subgroup analysis, the SF rate was significantly higher (81.6% vs 62.5%; p = 0.04) and the operative time was shorter for stones measuring 1-2 cm, whereas the results were similar for stones <1 cm and >2 cm. The lack of randomization and single-center design are the main limitations of the study. Conclusions: TFL and Ho:YAG lithotripsy are comparable in terms of the SF rate and safety for the treatment of UUT lithiasis. According to our study, for a cumulative stone size of 1-2 cm, TFL is more effective than Ho:YAG. Patient summary: We compared the efficiency and safety of two laser types for the treatment of stones in the upper urinary tract. We found that stone-free status at 3 months did not significantly differ between the holmium and thulium lasers.

Objective structured clinical examination versus traditional written examinations: a prospective observational study.

BACKGROUND: Recently, Objective Structured Clinical Examinations (OSCE) became an official evaluation modality for 6-year medical students in France. Before, standard examination modalities were: written progressive clinical cases (PCC), written critical reading of scientific articles (CRA), and internship evaluation (IE). The aim of this study was to assess the performances of 6-year medical students in their final faculty tests by comparing OSCE-exams with standard examination modalities. METHODS: This was a prospective observational study. We included all 6-year medical students in our university from 2020 to 2021. The endpoints were the scores obtained at the following final faculty tests during the 6th year of medical studies: OSCE-training, OSCE-exams, written PCC, written CRA, and IE. All scores were compared in a paired-analysis. RESULTS: A total of 400 students were included in the study. No student was excluded in the final analysis. The mean scores obtained at the OSCE-exams were significantly different from those obtained at OSCE-training, PCC, CRA, and IE (12.6 ± 1.7, 11.7 ± 1.7, 13.4 ± 1.4, 13.2 ± 1.5, 14.7 ± 0.9, respectively; p < 0.001). OSCE-exams scores were moderately and significantly correlated with OSCE-training and PCC (Spearman rho coefficient = 0.4, p < 0.001); OSCE examination scores were lowly but significantly correlated with CRA and IE (Spearman rho coefficient = 0.3, p < 0.001). OSCE-scores significantly increased after an OSCE training session. CONCLUSION: In our faculty, 6-year medical students obtained lower scores at OSCE exams compared to other standard evaluation modalities. The correlation was weak to moderate but significant. These results suggest that OSCE are not redundant with the other evaluation modalities. Interestingly, a single OSCE training session led to an improvement in OSCE scores underlining the importance of a specific training.

Persistent organochlorine pesticides in periprostatic adipose tissue from men with prostate cancer: Ethno-geographic variations, association with disease aggressiveness.

Although several studies have examined the relationship between organochlorine pesticides (OCPs) and prostate cancer (PCa) risk, no data are available concerning the association between OCPs concentrations in periprostatic adipose tissue (PPAT), which reflects cumulative exposure, and PCa aggressiveness. Moreover, no previous study has compared OCPs exposure in two distinct ethno-geographical populations. The objectives were to analyze OCPs in PPAT of PCa patients from either Mainland France or French West Indies in correlation with features of tumor aggressiveness, after adjusting for potential confounders such age, BMI, and polyunsaturated fatty acid (PUFA) content of PPAT. PPAT was analyzed in 160 patients (110 Caucasians and 50 African-Caribbeans), 80 with an indolent tumor (ISUP group 1 + pT2), and 80 with an aggressive tumor (ISUP group more than 3 + pT3). The concentrations of 29 OCPs were measured in PPAT concomitantly with the characterization of PUFA content. Exposure patterns of OCPs differed according to the ethno-geographical origin. Most OCPs were found at higher concentration in Caucasian patients, whereas pp'-DDE content was twice as high in African-Caribbeans. Chlordecone was only detected in PPAT from African-Caribbean patients. Most OCP concentrations were positively correlated with age, and some with BMI. After adjusting for age, BMI, and PUFA composition of PPAT, no significant association was found between OCPs content and risk of aggressive disease, except of mirex which appeared inversely associated with aggressive features of PCa in Caucasian patients. These results highlight a significant ethno-geographic variation in internal exposure to OCPs, which likely reflects differences in consumption patterns. The inverse relationship observed between mirex concentration and markers of PCa aggressiveness need to be further investigated.

Oncologic outcomes of patients with lymph node invasion at prostatectomy and post-prostatectomy biochemical persistence.

BACKGROUND: Pathologic nodal invasion at prostatectomy is frequently associated with persistently elevated prostate-specific antigen (PSA) and with increased risk of disease recurrence. Management strategies for these patients are poorly defined. We aimed to explore the long-term oncologic outcomes and patterns of disease progression. METHODS: We included men treated between 2000 and 2017 who had lymph node invasion at radical prostatectomy and persistently detectable prostate-specific antigen post-prostatectomy. Postoperative imaging and management strategies were collated. Patterns of recurrence and probability of metastasis-free survival, prostate cancer-specific survival, and overall survival (OS) were assessed. RESULTS: Among our cohort of 253 patients, 126 developed metastasis. Twenty-five had a positive scan within 6 months of surgery; of these, 15 (60%) had a nodal metastasis, 10 (40%) had a bone metastasis, and 4 (16%) had local recurrence. For metastasis-free survival, 5- and 10-year probabilities were 52% (95% CI 45%, 58%) and 37% (95% CI 28%, 46%), respectively. For prostate cancer-specific survival, 5- and 10-year probabilities were 89% (95% CI 84%, 93%) and 67% (95% CI 57%, 76%), respectively. A total of 221 patients proceeded to hormonal deprivation treatment alone. Ten patients received postoperative radiotherapy. CONCLUSIONS: Biochemical persistence in patients with lymph node invasion is associated with high risk of disease progression and reduced prostate cancer-specific survival. Management was hindered by the limitation of imaging modalities utilized during the study period in accurately detecting residual disease. Novel molecular imaging may improve staging and help design a therapeutic strategy adapted to patients' specific needs.

[Impact of delay before partial nephrectomy of a localized kidney tumor]. / Impact du délai avant prise en charge par néphrectomie partielle d'une tumeur du rein localisée.

INTRODUCTION: Partial nephrectomy is the treatment of choice for small localized renal tumors. In case of doubt, a biopsy can confirm the diagnosis. The aim of this study was to evaluate the impact of a delayed time to partial nephrectomy on cancer development. MATERIALS AND METHODS: Our single center study enrolled localized renal tumor patients who underwent a partial nephrectomy between 2015 and 2020; the collected data were included in the uroCCR prospective database. The histopathological stage of the tumors and the recurrence rate in patients treated with surgery >90 days after diagnosis were investigated. The impact a preoperative biopsy on was also explored. Statistical significance was tested using Student's t-test and Chi-squared test (SPSS software). RESULTS: The cohort consisted of 179 patients, among which 41 (23 %) received a preoperative biopsy. 89 patients (50 %) were treated surgically >3 months after diagnosis. The median time to nephrectomy was 86 days (13-1 037). A delayed time to surgery did not lead to significantly higher recurrence rates (P=0.66). Preoperative biopsy led to a doubling time to surgery (P<0.001) but was neither correlated to a more severe tumor stage (P=0.944) nor to a higher recurrence rate (P=0.08). Tumor growth was not significantly different with or without the presence of a biopsy (P=0.122). CONCLUSION: Our data evidence that a substantial delayed time to partial nephrectomy does not result in a negative impact on cancer prognosis in localized renal tumor patients.

Study of Post-Kidney Transplantation Parietal Complications and Presarcopenia.

BACKGROUND: Sarcopenia is defined as a loss of muscle mass and strength. Its effects on postoperative outcomes in oncology and geriatrics have already been shown. Approximately 40% of patients in end-stage renal failure are affected with sarcopenia. A recent study suggests that sarcopenia could predict surgical complications after renal transplantation in obese patients. The aim of this study was to evaluate the effect of sarcopenia on parietal complications (eg, wound healing, lymphocele, hematoma). METHODS: Two indices of muscle fat infiltration (intra-muscular adipose content [IMAC], Hounsfield unit average calculation [HUAC]) and 3 of muscle mass index (total psoas index [TPI], visceral fat area/total abdominal muscle area [VFA/TAMA], and skeletal muscle mass index [SMMI]) were retrospectively measured on pretransplant computed tomography scans for patients undergoing kidney transplantation between 2007 and 2017. Patients were considered sarcopenic when the index was above the third quartile for muscle fat infiltration (IMAC, HUAC) and VFA/TAMA, and under the first quartile for muscle mass (TPI, SMMI). The occurrence of wound healing, collection (hematoma and lymphocele), and acute rejection were compared between sarcopenic and nonsarcopenic patients. RESULTS: Of 484 transplanted patients, 117 patients had a computed tomography scan before transplantation. Patients with a high HUAC had significantly more collections (P = .02) and total parietal complications (P = .09). Patients with a high IMAC had significantly more acute rejection (P = .001). CONCLUSIONS: Muscle fat infiltration appears to influence the outcome of renal transplantation. The management of sarcopenia in pretransplantation should be a subject of further research.

Does the Time to Start First-Line Treatment Influence the Survival of Favorable-Risk Patients With Metastatic Renal Cell Carcinoma? Results of the MetaSurv-UroCCR 79 Study.

INTRODUCTION AND OBJECTIVES: Many patients in the favorable International Metastatic renal cell carcinoma (RCC) Data Base Consortium group (F-MRC) may have a relatively indolent disease course. Surveillance and delay of systemic therapy could be an option in this specific population. However, the question whether this delay could alter patients' outcome remains unanswered. Our objective was to determine if delaying first-line treatment influences the survival of F-MRC patients. MATERIALS AND METHODS: We performed a retrospective multicenter national study involving the French Network for Research on Kidney Cancer UroCCR (NCT03293563). We included treatment naive F-MRC patients. We compared the overall survival of patients with immediate medical treatment (IMT) (started less than 3 months after metastatic diagnosis) to those with delayed medical treatment (DMT). RESULTS: We included 90 patients treated between 2009 and 2018. The median time before occurrence of metastases from diagnosis was 28 (12-137) months. The two groups (IMT vs. DMT) were comparable for follow-up, age, sarcomatoid feature, number, and localization of metastatic sites and ECOG performance status. IMT was given in 25 (27.8 %) patients. Local treatment of metastasis (LTM) was performed in 47 (52%) patients. Patients with DMT had more LTM (63% vs. 24%, P = .001). Among patients with DMT (n = 65); 27 (41%) received a systemic treatment and median systemic treatment-free survival was 39 months (95% CI, 26.3-51.6). Median overall survival from metastasis disease diagnosis was 55 months (95% CI, 42.4-67.5) in the IMT group and 88 months (95%CI, 64-111.9) in the DMT group (P = .028). In multivariable analysis LTM was the only prognostic factor associated to survival improvement (HR: 0.33; P = .024). CONCLUSIONS: Selected Patients with F-MRC may safely undergo DMT. LTM positively impacted survival in this population and should be considered whenever possible. Prospective trial with a larger population is needed to confirm these results.

Antibiotic therapy impact on intravesical BCG therapy efficacy for high-risk localized bladder cancer treatment.

Intravesical Bacillus Calmettes-Guerin (BCG) instillations is the gold standard adjuvant treatment for high and very high-risk non-muscle-invasive bladder cancer (NMIBC). Antibiotics may be required to treat asymptomatic bacteriuria before instillations or to prevent side effects. By modifying the bladder microbiota and through its bactericidal action, it could modify the efficacy of BCG. This study evaluates the impact of antibiotics received during BCG-induction treatment on the oncological outcomes for high and very high risk NMIBC. We retrospectively included all patients who received a full induction regimen of BCG therapy between January 2017 and June 2022. Clinical and tumor characteristics as well as tolerability were collected. Recurrence-free survival (RFS) and progression-free survival (PFS) were compared according to the prescription of antibiotics, its type and duration. A total of 126 patients were included, 86.5% of the tumors were high risk and 13.5% very high risk. The median follow-up was 31 months (7-60). 36% of the patients received antibiotics during BCG-induction treatment (among which 44% received fluoroquinolones). 21.4% of patients had tumor recurrence. There was no difference in RFS (p=0.902) or PFS (p=0.88) according to the duration or the type of antibiotics received. The use of a prolonged antibiotic treatment (> 7 days) significantly increased the duration of the BCG-induction treatment from 35 to 41,5 days (p=0,049) and the median number of delayed treatments by 1,5 [0-4]. Neither the use of antibiotics nor their duration modified the risk of recurrence or the intensity of side effects in multivariate analysis. Antibiotics received during BCG-induction immunotherapy did not influence oncological short-term outcomes or intensity of side effects.

Assessment of the Compliance of Cystitis Management According to French Recommendations through the Analysis of Prescriptions Collected in Community Pharmacies.

Urinary tract infections, especially cystitis, are common infections; they are the second most prevalent cause of antibiotic prescriptions in community pharmacies. To reduce antimicrobial resistance, guidelines are revised regularly. This study aims to assess compliance between prescriptions collected in community pharmacies and French cystitis guidelines. A treatment is considered compliant if the nature, dosage, and duration of the antibiotics are correct. Only women aged 18-65 years with a diagnosis of cystitis were eligible. The participation of 16 pharmacies resulted in 303 prescriptions. Most infections were classified as uncomplicated cystitis (79.2%), general practitioners were the prescribers in more than 9 out of 10 cases, and fosfomycin trometamol was the antibiotic dispensed for 1 in 2 women. An average compliance of 66% was observed, but with disparities according to the type of cystitis. Two-thirds of cases of uncomplicated cystitis and recurrent cystitis followed the recommendations, whereas only 15% of cystitis cases that were at risk of complication did so. The inclusion of a urine examination in uncomplicated cystitis decreased the overall compliance rate to 5.8%. These results show the essential role played by pharmacists; they are the last line of defence before dispensing antibiotics. They must know the recommendations in order to apply them.

Script concordance test acceptability and utility for assessing medical students' clinical reasoning: a user's survey and an institutional prospective evaluation of students' scores.

Script Concordance Testing (SCT) is a method for clinical reasoning assessment in the field of health-care training. Our aim was to assess SCT acceptability and utility with a survey and an institutional prospective evaluation of students' scores.With a user's online survey, we collected the opinions and satisfaction data of all graduate students and teachers involved in the SCT setting. We performed a prospective analysis comparing the scores obtained with SCT to those obtained with the national standard evaluation modality.General opinions about SCT were mostly negative. Students tended to express more negative opinions and perceptions. There was a lower proportion of negative responses in the teachers' satisfaction survey. The proportion of neutral responses was higher for teachers. There was a higher proportion of positive positions towards all questions among teachers. PCC scores significantly increased each year, but SCT scores increased only between the first and second tests. PCC scores were found significantly higher than SCT scores for the second and third tests. Medical students' and teachers' global opinion on SCT was negative. At the beginning SCT scores were found quite similar to PCC scores. There was a higher progression for PCC scores through time.

A comparison of oncologic and functional outcomes in patients with pt3a renal cell carcinoma treated with partial and radical nephrectomy

ABSTRACT Hypothesis: Partial Nephrectomy is oncological safe in patients with pT3a RCC. Purpose: To compare the oncological and functional outcomes of patients with pT3a RCC scheduled for PN and RN. Materials and Methods: We retrospectively reviewed patients with pT3a N0 M0 RCC who underwent partial or radical nephrectomy from 2005 to 2016. Perioperative characteristics, including estimated glomerular filtration rate, tumor size, pathological histology, and RENAL nephrometry score, were compared between patients scheduled for partial or radical nephrectomy. We used multivariable Cox proportional hazards regression models to compare overall survival, cancer-specific survival, and recurrence-free survival between planned procedure type. Results: Of the 589 patients, 369 (63%) and 220 (37%) were scheduled for radical and partial nephrectomy, respectively; 26 (12%) of the scheduled partial nephrectomy cases were intraoperatively converted to radical nephrectomy. After adjusting for tumor size and histology, there were no statistically significant differences in overall survival (hazard ratio 0.66; 95% CI, 0.38-1.13), cancer-specific survival (hazard ratio 0.53; 95% CI, 0.16-1.75), or recurrence-free survival (hazard ratio 0.66; 95% CI, 0.34-1.28) between patients scheduled for partial or radical nephrectomy. Fewer patients scheduled for partial nephrectomy had estimated glomerular filtration rate reductions 3 to 9 months after surgery than patients scheduled for radical nephrectomy. Conclusion: We found no evidence that patients scheduled to undergo partial nephrectomy had poorer oncologic outcomes than patients scheduled to undergo radical nephrectomy. In select patients with pT3a renal cell carcinoma in whom partial nephrectomy is deemed feasible by the surgeon, partial nephrectomy should not be discouraged.

Combined OX40 Agonist and PD-1 Inhibitor Immunotherapy Improves the Efficacy of Vascular Targeted Photodynamic Therapy in a Urothelial Tumor Model.

PURPOSE: Vascular targeted photodynamic therapy (VTP) is a nonsurgical tumor ablation approach used to treat early-stage prostate cancer and may also be effective for upper tract urothelial cancer (UTUC) based on preclinical data. Toward increasing response rates to VTP, we evaluated its efficacy in combination with concurrent PD-1 inhibitor/OX40 agonist immunotherapy in a urothelial tumor-bearing model. EXPERIMENTAL DESIGN: In mice allografted with MB-49 UTUC cells, we compared the effects of combined VTP with PD-1 inhibitor/OX40 agonist with those of the component treatments on tumor growth, survival, lung metastasis, and antitumor immune responses. RESULTS: The combination of VTP with both PD-1 inhibitor and OX40 agonist inhibited tumor growth and prolonged survival to a greater degree than VTP with either immunotherapeutic individually. These effects result from increased tumor infiltration and intratumoral proliferation of cytotoxic and helper T cells, depletion of Treg cells, and suppression of myeloid-derived suppressor cells. CONCLUSIONS: Our findings suggest that VTP synergizes with PD-1 blockade and OX40 agonist to promote strong antitumor immune responses, yielding therapeutic efficacy in an animal model of urothelial cancer.

Prostate cancer detection by targeted prostate biopsy using the 3D Navigo system: a prospective study.

PURPOSE: The 3D Navigo™ system is a magnetic resonance imaging (MRI) and transrectal ultrasound (TRUS) fusion device for prostate targeted biopsies (TB). Our aim was to evaluate the clinically significant prostate cancer (CSC) detection rate of TB using the 3D Navigo™ system. METHODS: Patients who underwent TB with the 3D Navigo™ system in our center between June 2014 and May 2018 were prospectively included, excluding those who have previously received treatment for prostate cancer. A 3-Tesla MRI imaging was performed before biopsies; findings were reported according to the Prostate Imaging Reporting and Data System version 2 (PIRADS). CSC was defined by an ISUP score ≥ 2. RESULTS: 304 patients underwent TB. Median age was 66 years (51-84). Median PSA was 7.75 ng/ml (0.6-70.0). Median prostate volume was 45.0 ml (15.9-221.7). PCa and CSC were found in 70.4% (214/304) and 47.7% (145/304) of the patients, respectively. The proportion of patients diagnosed with CSC among those with PCa was 67.8% (145/214). There was a significant risk of having a CSC in case of PIRADS score ≥ 4 and 5 (OR 5.0, 95% CI [2.7-9.2], P < 0.001; OR 3.2, 95% CI [1.8-5.5], P < 0.001). PIRADS score was an independent risk factor of having a CSC (OR 4.19, 95% CI [2.49-7.05], P < 0.001). There was no significant difference between pathological outcomes of TB and RP in paired analysis (P = 0.892). There was a correlation between TB and RP specimens for PCa detection (r = 0.60, P < 0.001). CONCLUSION: Detecting CSC with MRI-TRUS fusion targeted biopsies using the 3D Navigo™ system is feasible and safe. We found a positive correlation between TB and RP for ISUP scores.
