RESUMO
AIM: To evaluate and identify predictors of psychosocial distress (PD) in patients after surgical treatment for prostate cancer (PC), bladder cancer (BC), or kidney cancer (KC) during the COVID-19 pandemic in a large, multi-institutional cohort. MATERIAL AND METHODS: Patients undergoing inpatient rehabilitation (IR) after radical prostatectomy (RP), radical cystectomy (RC), or (partial) nephrectomy in one IR center in 2021 were included. PD was evaluated by the Questionnaire on Stress in Cancer Patients (QSC-R23) at the beginning (T1) and the end (T2) of IR. Regression analyses were performed to identify disease-specific predictors for high PD. RESULTS: A total of 4,290 patients (3,413 after RP, 563 after RC, 314 after (partial) nephrectomy) were included in this study. Median PD decreased significantly during IR across all tumor entities (each p < 0.001). The number of PC and BC patients suffering from high PD decreased significantly (each p < 0.001), but not in KC patients (p = 0.310). Younger age independently predicts high PD in all three malignancies, while additionally positive surgical margins (p = 0.016), ileal conduit (IC; p < 0.001), and nephrectomy (p = 0.032) independently predict high PD in PC, BC, and KC patients, respectively. During the Covid-19 pandemic the demand for individual psycho-oncologic counseling increased significantly in PC (p = 0.03) and KC (p = 0.001) patients. CONCLUSION: Younger age independently predicts high PD in the three main urological malignancies. Positive surgical margins in PCa, IC in BCa, and nephrectomy in KC are disease-specific independent predictors for high PD in the early period after surgical treatment. IMPLICATIONS FOR CANCER SURVIVORS: Disease-specific predictors for high PD may help clinicians identify patients at risk and may guide timely referrals to psycho-oncologic counseling in the early period after uro-oncologic surgery.
RESUMO
OBJECTIVE: Antibody-drug conjugates (ADC), enfortumab-vedotin (EV) and sacituzumab-govitecan are new drugs in the treatment of urologic tumors, whose safety profile has not been fully investigated. Therefore, the aim of our study was to evaluate adverse events related to both agents reported to VigiBase, the World Health Organization's global pharmacovigilance database. METHODS: We employed Bayesian disproportionality analysis based on the information component (IC) to explore the safety profile associated with both therapies. Additionally, we used the proportional reporting ratio approach to examine the safety profile further. RESULTS: We identified 41,752 reports connected to ADC therapy (EV: n=5359; SG: n=36,393). In the EV subgroup, most reports were associated with dermatologic (38.6%), neurologic adverse events (16.5%), or adverse laboratory assessments (19.4%). In contrast, reports in the SG subgroup were mainly associated with gastrointestinal adverse events (24.2%) and adverse laboratory assessments (39.0%). Adverse laboratory assessments in both cohorts were often based on haematotoxic adverse events. CONCLUSION: We could provide a comprehensive real-world safety profile of EV and SG using a global pharmacovigilance database. Based on the safety signals explored in this study, further research regarding the impact of these side effects on patient outcomes is justified.

Bone marrow metastases-noted in 6% of patients with rhabdomyosarcoma-have been linked to very poor outcomes. Bilateral bone marrow sampling from iliac crests has been the gold standard for bone marrow examination in rhabdomyosarcoma, but sampling errors due to patchy bone marrow involvement may limit its sensitivity. Here, we report the case of a 6-year-old boy with embryonal rhabdomyosarcoma of the skull base and multiple 2-[18F]fluoro-2-deoxy-D-glucose (2-[18F]FDG)-avid bone marrow metastases visualized by positron emission tomography and computed tomography (2-[18F]FDG PET/CT). His bone marrow aspirates were tumor-free. This case illustrates the diagnostic value of 2-[18F]FDG PET/CT in the detection of bone marrow metastases in rhabdomyosarcoma patients, which may re-shape the definition of bone marrow disease and, ultimately, alter disease staging and risk stratification.

INTRODUCTION: The aim of the study was to determine the adaption of neoadjuvant chemotherapy (NAC) in patients with muscle-invasive bladder cancer (MIBC) in Germany, Austria, and Switzerland and especially underlying reasons for potential low adherence to guidelines. METHODS: We conducted a non-validated survey among 336 urologic departments in Germany, Austria, and Switzerland. RedCap questionnaires were electronically distributed and included 23 items concerning the general NAC administration standards and guideline compliance in patient counseling regarding the actual treatment. RESULTS: The return rate of the questionnaire was 19.1% (63/336). Although 45 departments (71.4%) claim to perform NAC as the standard of care, only 49% of eligible patients actually receive NAC. An advanced disease stage (≥cT3) and a high tumor volume were mentioned to support the application of NAC, whereas 35% of responders worry about deterioration of patients' preoperative status due to NAC. Furthermore, 26.7% of respondents are concerned about the low extent of survival benefit. CONCLUSION: Application of NAC in eligible MIBC patients in Germany, Austria, and Switzerland remains low. Although the majority of urologic departments discuss NAC and acknowledge the need for intensified treatment in advanced disease stages, not all eligible patients will actually receive NAC before radical cystectomy.

PURPOSE: To evaluate return to work (RTW), health-related quality of life (HRQoL) and psychosocial distress (PD) after radical cystectomy (RC) and creation of an ileal conduit (IC) or an orthotopic ileal neobladder (NB) for bladder cancer. METHODS: The study relied on prospectively collected data for 842 patients, who underwent 3 weeks of inpatient rehabilitation (IR) after surgery between April 2018 and December 2019. HRQoL (EORTC QLQ-C30) and PD (Questionnaire on Stress in Cancer Patients [QSC-R10]) were evaluated at the beginning (T1) and end (T2) of IR as well as both 6 (T3) and 12 months after surgery (T4). Regression analyses were performed to identify predictors of HRQoL and RTW, respectively. RESULTS: Two hundred thirty patients (IC n = 51, NB n = 179) were employed before surgery (27.3%). HRQoL improved steadily, while high PD was present in 51.0% of patients at T4. RTW rate was 86.8 and 80.6% at T3 and T4, respectively. Linear regression analysis identified RTW as the only predictor for better HRQoL at T4 (OR [odds ratio] 12.823, 95% CI [confidence interval] 2.927-22.720, p = 0.012). Multivariate regression analysis identified age ≤ 59 years (OR 7.842; 95% CI 2.495-24.645; p < 0.001) as an independent positive predictor and lymph node metastasis (OR 0.220; 95% CI 0.054-0.893; p = 0.034) as an independent negative predictor of RTW at T4. CONCLUSION: Global HRQoL improved steadily during the follow-up and RTW rates are high. However, patients often reported high PD, reflecting a need for additional psychosocial support within aftercare.

BACKGROUND: In slipped capital femoral epiphysis (SCFE), the femoral head slides in an anterosuperior direction along the growth plate. The femoral head remains in the acetabulum. The pathogenesis of SCFE is multifactorial. An important predisposing factor is obesity. PROBLEM: Epiphysiolysis can compromise the blood supply to the epiphysis and osteonecrosis of the femoral head may result. DIAGNOSTICS AND PROGNOSIS: Conventional radiography represents the first diagnostic step. The long-term prognosis of the disease depends on the residual deformity of the femoral head and in the worst case may result in early osteoarthritis of the hip joint.

OBJECTIVES: To assess the impact of urinary continence and erectile function on the quality of life in men undergoing radical prostatectomy (RP) for prostate cancer (PC), we analyzed the preoperative and 1-year postoperative outcomes of five functional domains and their influencing factors. PATIENTS AND METHODS: In this prospective study, all patients undergoing open or robot-assisted RP between Febuary 2017 and March 2020 in a single academic center were included. Patient-reported outcomes were assessed pre- and 12 months postoperatively using the Expanded Prostate Index Composite (EPIC-26) survey, evaluating continence, irritative/obstructive micturition, gastrointestinal symptoms, sexuality, and overall vitality. We examined the impact of RP on sexual function and urinary continence using multivariable logistic regression models, accounting for patient and tumor characteristics. RESULTS: Overall, 1313 consecutive patients gave consent for study participation and completed both surveys. The median age was 66 years (IQR: 60-70). The majority of patients (n = 601, 46%) had an intermediate risk PC. Robotic RP was performed in 71.6% and nerve-sparing technique in 81% of the cases. The median pre- versus postoperative scores were the following: urinary continence 100 (IQR: 91.8-100) versus 85.5 (64.8-100), irritative micturition 87.5 (IQR: 75-100) versus 93.8 (IQR: 87.5-100), gastrointestinal symptoms the same with 100 (IQR: 95.8-100), vitality 95 (IQR: 80-100) versus 90 (IQR: 75-100), and erectile function 65.3 (IQR: 38.8-87.5) versus 22.2 (IQR: 12.5-48.7), respectively. Age (p < 0.001), risk classification (p = 0.002), and nerve-sparing surgery (p = 0.016) were associated with good sexual function (EPIC-26 score ≥60), while only age (p = 0.001) was statistically significantly associated with good urinary continence (EPIC-26 score ≥80). CONCLUSION: Non-modifiable factors such as age and PC risk classification impact urinary continence and sexual function after RP. Nevertheless, urologic surgeons should further focus on improving nerve-sparing techniques, the only modifiable variable, to reduce the surgery's negative impact on urinary continence and sexual function.

INTRODUCTION AND OBJECTIVES: Decision-making to perform prostate biopsy should include individual risk assessment. Patients classified as low risk by the Rotterdam Prostate Cancer Risk Calculator are advised to forego biopsy (PBx). There is concern about missing clinically significant prostate cancer (csPCa). A clear pathway for follow-up is needed. MATERIAL AND METHODS: Data for 111 consecutive patients were collected. Patients were encouraged to adhere to a PSA-density-based safety net after PBx was omitted. Cut off values indicating a re-evaluation were PSA density >0.15 ng/mL/ccm in PBx-naïve patients and >0.2 ng/mL/ccm in men with past-PBx. Primary endpoint was whether men had their PSA taken regularly. Secondary endpoint was whether a new multiparametric MRI was performed when PSA-density increased. Tertiary endpoint was whether biopsy was performed when risk stratification revealed an increased risk. RESULTS: Median follow-up was 12 months (IQR 9-15 months). The primary endpoint was reached by 97.2% (n = 106). The secondary endpoint was reached by 30% (n = 3). The tertiary endpoint was reached by 50% (n = 2). Histopathologic analyses revealed csPCa in none of these cases. Risk stratification did not change (p = 0.187) with the majority of patients (89.2%, n = 99). CONCLUSION: The concern of missing csPCa when omitting PBx in the risk-stratified pathway may be negated. Changes in risk stratification during follow-up should lead to subsequent PBx. We suggest implementing a safety net based on PSA density and digital rectal examination (DRE).

INTRODUCTION: Evidence of transperineal (TP) superiority over transrectal (TR) biopsy is growing due to lower infectious complication rates. However, TR biopsy is the most common procedure, and it seems that a cross-over to TP is delayed by logistical challenges such as costs, complexity, and lack of experience. We investigate whether well-selected patients without any risk factors may further undergo TR biopsy if all precautions to avoid infections are warranted. MATERIALS AND METHODS: Data were collected in our academic institution between August 2021 and March 2022 and after clinical implementation of the currently updated European Association of Urology guideline recommendations on the performance of prostate biopsy. Patients underwent either TP or TR biopsy according to a riskstratification based on risk factors of infectious complications. Follow-up asked for post-biopsy complications. Inverse Probability of Treatment Weighting (IPTW) propensity score was used to balance baseline characteristics. Complications were subdivided into infectious and non-infectious complications. RESULTS: In total, 294 patients were included with 161 patients undergoing TR vs. 133 patients undergoing TP biopsy. Complication rates were 2.2% for TP vs. 5.5% for TR biopsy concerning all complications. Infectious complication rates only were 0.7% for TP vs. 1.8% for TR biopsy. After IPTW adjustment, differences were statistically significant different (p = 0.01). CONCLUSION: Our study revealed that even in a well-selected patient cohort with presumably lower risk of infectious complications, TR biopsy leads to more post-biopsy complications than TP biopsy. This conclusion should motivate the urological community to switch to TP biopsy.

Background: Generalized lymphatic anomaly (GLA), Gorham-Stout disease (GSD), kaposiform lymphangiomatosis (KLA), and central conducting lymphatic anomaly (CCLA) are rare, multisystem lymphatic disorders, referred to as complex lymphatic anomalies (CLAs). Their etiology remains poorly understood; however, somatic activating mutations have recently been discovered, and the results of targeted treatments are promising. This study aimed to elaborate on the phenotypic description of CLA. Methods: Thirty-six consecutive patients were recruited for the "GLA/GSD Registry" of the University Hospital of Freiburg, Germany (2015-2021). Clinical data were prospectively collected provided that a signed informed consent form was obtained. The latest proposed diagnostic guidelines were retrospectively applied. Results: Thirty-two patients (38% males) were included in the study; 15 GLA, 10 GSD, 3 KLA, and 4 CCLA patients were identified. Eighty-four percent already had symptoms by the age of 15 years. Osteolysis and periosseous soft-tissue infiltration were associated with GSD (p < 0.001 and p = 0.011, respectively), ascites and protein-losing enteropathy with CCLA (p = 0.007 and p = 0.004, respectively), and consumption coagulopathy with KLA (p = 0.006). No statistically significant differences were found in organ involvement, distribution of osteolytic lesions, number of affected bones and fractures. Twenty-five patients had complications; one patient with GLA died despite multimodal treatment. Spontaneous regression was seen in one patient with untreated KLA. Conclusions: CLA are rare, and their overlapping clinical presentations make differential diagnosis difficult. The characterization of our case series contributes to the phenotypic description and differentiation of these four clinical entities. A further understanding of their pathogenesis is crucial for evaluating targeted therapies and optimizing medical care.

BACKGROUND: Sarcomatoid differentiation in patients diagnosed with renal cell carcinoma (sRCC) imply aggressive behavior and often metastatic disease at the time of diagnosis. We aim to examine the overall survival (OS) in patients with sRCC using the National Cancer Database (NCDB). MATERIALS AND METHODS: We identified patients diagnosed with sRCC between 2010-2015. We employed Kaplan-Meier curves and multivariable Cox proportional hazards regression models to examine the impact of several potential risk factors on OS in patients diagnosed with sRCC. RESULTS: In total, 8582 patients with renal cancer were found to have sarcomatoid differentiation, with 4105 patients (47.8%) being diagnosed with AJCC stage IV disease. The median OS was 17.2 months (IQR 5.4, 68.7 months). Compared to patients who did not undergo surgery, OS was significantly longer in patients undergoing partial or total nephrectomy across all stages. This result remained consistent on multivariable Cox proportional hazards regression adjusting for patient and tumor characteristics (Surgery: Hazard ratio 0.54, 95%Confidence interval 0.43 - 0.68, P < .001). CONCLUSION: In our cohort sRCC was found to have an unfavorable median OS, which was mainly caused by the high number of cases diagnosed with late-stage disease. Additionally, surgery was associated with favorable OS across all stages. This study supports the notion that surgical therapy, even in the setting of cytoreductive surgery, provides a survival benefit in patients with sRCC.

A number of different acquired pathologies can affect the pediatric hip joint. The classical and relatively common reactive, inflammatory or traumatic entities have to be differentiated from each other. Rarer and very rare pathologies, such as neoplastic entities or tenosynovial giant cell tumor, must also be considered in the differential diagnostics. The correct diagnosis, treatment planning and follow-up monitoring require close coordination between the departments of pediatric radiology and pediatric orthopedics. Sonography often represents the initial diagnostic step, followed by conventional radiography. Further evaluation of hip joint pathologies requires magnetic resonance imaging. In selected cases computed tomography can also be indicated.

INTRODUCTION: This study aimed to investigate the number of cores needed in a systematic biopsy (SB) in men with clinical suspicion of prostate cancer (PCa) but negative prebiopsy multiparametric magnetic resonance imaging and to test prostate-specific antigen (PSA) density as an indicator for reduced SB. METHODS: Two hundred and seventy-four patients were analyzed, extracted from an institutional database. Detection rates of any PCa and clinically significant (CS) PCa for different reduced biopsy protocols were compared by using Fisher's exact test. RESULTS: In total, 12-core SB revealed PCa in 103 (37.6%) men. Detection rates of reduced biopsy protocols were 74 (27%, 6-core) and 82 (29.9%, 8-core). Regarding CSPCa, 12-core SB revealed a detection rate of 26 (9.5%). Reduced biopsy protocols detected less CSPCa: 15 (5.5%) and 18 (6.6%), respectively. All differences were statistically significant, p < 0.05. PSA density ≥0.15 did not help to filter out men in whom a reduced biopsy may be sufficient. CONCLUSIONS: Twelve-core SB still has the highest detection rate of any PCa and CSPCa compared to reduced biopsy protocols. If the investigator and patient agree - based on individual risk calculation - to perform a biopsy, this SB should contain at least 12 cores regardless of PSA density.

PURPOSE: This study aimed to evaluate psychosocial distress in the context of continence and oncological outcome during the early recovery period after radical prostatectomy (RP) for prostate cancer. PATIENTS AND METHODS: Retrospectively collected data from 587 patients who underwent inpatient rehabilitation after RP in 2016 and 2017 were analyzed. Psychosocial distress (measured by using a Questionnaire on Stress in Cancer Patients [QSC-R10]) and continence status (urine loss on a 24-h pad test and urine volume on uroflowmetry) were evaluated at the beginning (T1) and end (T2) of a 3-week inpatient rehabilitation. Multivariate logistic regression was performed to identify predictors for high distress (QSC-R10 score ≥15). RESULTS: The median patient age was 65 years. At the start of rehabilitation, 204 patients (34.8%) demonstrated high distress. Psychosocial distress decreased significantly (p < 0.001) from a median of 11.0 at T1 (median 16 days after surgery) to a median of 6.0 at T2 (median 37 days after surgery). Complete continence increased significantly (p < 0.001) from 39.0% at T1 to 58.9% at T2. The median urine volume increased significantly (p < 0.001) from 161 mL at T1 to 230 mL at T2. Often, distress is higher in younger patients, whereas incontinence is higher in older patients. Multivariate logistic regression analysis identified age ≤69 years (p = 0.001) and tumor stage ≥pT3 (p = 0.006) as independent predictors of high distress. CONCLUSIONS: Distress and incontinence decreased significantly during the 3 weeks of inpatient rehabilitation after RP. Patient age ≤69 years and tumor stage ≥pT3 are independent predictors of high psychosocial distress.

BACKGROUND: Magnetic resonance imaging (MRI)-targeted prostate biopsy is a routinely used diagnostic tool for prostate cancer (PCa) detection. However, a clear superiority of the optimal approach for software-based MRI processing during biopsy procedures is still unanswered. To investigate the impact of robotic approach and software-based image processing (rigid vs. elastic) during MRI/transrectal ultrasound (TRUS) fusion prostate biopsy (FBx) on overall and clinically significant (cs) PCa detection. METHODS: The study relied on the instructional retrospective biopsy data collected data between September 2013 and August 2017. Overall, 241 men with at least one suspicious lesion (PI-RADS ≥ 3) on multiparametric MRI underwent FBx. The study protocol contains a systematic 12-core sextant biopsy plus 2 cores per targeted lesion. One experienced urologist performed 1048 targeted biopsy cores; 467 (45%) cores were obtained using rigid processing, while the remaining 581 (55%) cores relied on elastic image processing. CsPCa was defined as International Society of Urological Pathology (ISUP) grade ≥ 2. The effect of rigid versus elastic FBx on overall and csPCa detection rates was determined. Propensity score weighting and multivariable regression models were used to account for potential biases inherent to the retrospective study design. RESULTS: In multivariable regression analyses, age, prostate-specific antigen (PSA), and PIRADS ≥ 3 lesion were related to higher odds of finding csPCa. Elastic software-based image processing was independently associated with a higher overall PCa (odds ratio [OR] = 3.6 [2.2-6.1], p < 0.001) and csPCa (OR = 4.8 [2.6-8.8], p < 0.001) detection, respectively. CONCLUSIONS: Contrary to existing literature, our results suggest that the robotic-driven software registration with elastic fusion might have a substantial effect on PCa detection.

INTRODUCTION: The risk of occult prostate carcinoma (PCa) after negative multiparametric MRI (mpMRI)-transrectal fusion biopsy (F-Bx) is unknown. To determine the false-negative predictive value, we examined PCa detection after prior negative F-Bx. METHODS: Between December 2012 and November 2016, 491 patients with suspected PCa and suspicious mpMRI findings underwent transrectal F-Bx. Patients with benign pathology (n = 191) were eligible for our follow-up (FU) survey. Patient characteristics and clinical parameters were correlated to subsequent findings of newly detected PCa. RESULTS: Complete FU with a median of 31 (interquartile range: 17-39) months was available for 176/191 (92.2%) patients. Of those, 54 men had either surgical interventions on the prostate or re-Bxs. Newly detected PCa was evident in 14/176 (7.95%) patients stratified to ISUP ≤2 in 10 and ≥3 in 4 cases. The comparison of patients with newly detected PCa to those without cancerous findings in FU showed significant differences in prostate-specific antigen (PSA) density (0.16 vs. 0.13 ng/mL2) and prostate volume (45 vs. 67 mL, both p < 0.05). Both factors are significant predictors for newly detected cancer after initial negative F-Bx. CONCLUSION: Only PSA density (>0.13 ng/mL2) and small prostate volume are significant predictors for newly detected PCa after initial negative F-Bx. Despite negative mpMRI/TRUS F-Bx results, patients should be further monitored due to a risk of developing PCa over time. Notwithstanding the limitation of our study that not all patients underwent another Bx, we assume that the false-negative rate is low but existing. Our data represent a real-world scenario.

The age-dependent development of the bone marrow follows a constant pattern and has an impact on the localization and morphology of various bone marrow processes. Physiological, reactive and benign bone marrow alterations must be differentiated from inflammatory or malignant infiltrations. In many cases, a specific age distribution pattern and typical morphological characteristics in magnetic resonance imaging (MRI) enable a diagnostic classification. The only adequate imaging modality that can provide information about the bone marrow composition is MRI.

BACKGROUND: Multiparametric magnetic resonance imaging using the Prostate Imaging Reporting and Data System version 2.1 allows for a personalized, risk-stratified approach to indicating prostate biopsies (PBx) in order to reduce PBx and concomitant complications in men with suspected prostate cancer (PCa). One way to achieve this goal is to implement the risk-stratified pathway (RSP) using the Rotterdam Prostate Cancer Risk Calculator. OBJECTIVE: To describe the clinical implementation of the RSP and to examine its impact on the number of PBx and the resulting changes in the PCa detection pattern compared with men undergoing PBx in a detection-focused pathway (DFP) without prior risk assessment. DESIGN, SETTING, AND PARTICIPANTS: An institutional dataset of 505 consecutive patients with suspected PCa between July 2019 and February 2020 was used. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Chi-square test and Mann-Whitney U test were employed to examine differences in the number of PBx and the PCa detection pattern between the DFP (n = 195, 38.6%) and the RSP (n = 310, 61.4%). To minimize differences in risk stratification, inverse probability of treatment weighting was used. RESULTS AND LIMITATIONS: After implementing the RSP, the overall biopsy rate could be reduced by 11.2% (100% vs 88.8%, p < 0.001. Additionally, compared with the DFP, the number of biopsy cores per patient was reduced in the RSP (14 [interquartile range {IQR} 14-15] vs 14 [IQR 6-14], p < 0.001) and the detection of clinically significant PCa was increased (44.3% vs 57.7%, p = 0.038). Overdiagnosis of clinically insignificant disease was decreased in the RSP (22.8% vs 12.6%, p = 0.039). CONCLUSIONS: Implementation of the RSP in clinical practice reduced the number of PBx and brought forth a shift in the PCa detection pattern toward clinically significant disease, while reducing overdiagnosis of clinically insignificant disease. PATIENT SUMMARY: In this study, we examined the impact of risk stratification on the number of prostate biopsies (PBx) and the consecutive detection pattern in men with suspected prostate cancer (PCa). We found that the risk-stratified pathway reduced the number of PBx while simultaneously shifting the PCa detection pattern toward clinically significant PCa.
