RESUMO

INTRODUCTION: Large Language Models (LLMs) such as ChatGPT have rapidly brought the application of artificial intelligence into widespread use. Among many different use cases for text generation and processing, one application is the extraction of data from existing documents and conversations for simplified and automated form-filling. OBJECTIVE: In the field of quality assurance and documentation of cancer diseases, there is currently a significant workload involved in transferring data under various aspects into slightly varying formats and applying interpretations such as the TNM classification of tumours. However, there is a lack of trials with real data to assess the applicability of LLM-supported processes in this area, which would enable an evaluation of efficiency and practicality. This study aims to implement and assess such a trial. METHODOLOGY: A trial was conducted with N=153 privacy-compliant and ethics committee-cleared medical reports from 25 patients. Using the publicly available version of ChatGPT 4.0, an automated script was used to extract the date of initial diagnosis and common tumor classifications. The results were then individually checked for accuracy. Based on this, the utility of a simple system for guided support in tasks related to tumour documentation was assessed. Additionally, the approach was evaluated in terms of operational costs for the model and its applicability. RESULTS: In summary, the study concludes that the use of generative AI in this field is promising and suitable as a tool even in an untrained state. In a simplified calculation, costs of 35 cents are offset by a value creation of 61,54 euros. However, it also becomes clear that AI can only act in a supportive role, and the correct integration with pre-made specific prompts and tools into the workflow is crucial for a relevant performance. CONCLUSION: The use of generative AI in the context of search, transfer, and interpretation tasks in the creation of tumor documentation is a promising approach. However, its implementation in practical applications must be closely monitored, and the optimal interaction between man and machine should continue to be evaluated and must be accompanied by tools and task-specific prompts.

RESUMO

PURPOSE: Androgen deprivation therapy (ADT) is the mainstay approach for prostate cancer (PCa) management. However, the most commonly used ADT modality, gonadotropin-releasing hormone (GnRH) agonists, has been associated with an increased risk of cardiovascular disease (CVD). METHODS: The PCa Cardiovascular (PCCV) Expert Network, consisting of multinational urologists, cardiologists and oncologists with expertise in managing PCa, convened to discuss challenges to routine cardiovascular risk assessment in PCa management, as well as how to mitigate such risks in the current treatment landscape. RESULTS: The experts identified several barriers, including lack of awareness, time constraints, challenges in implementing risk assessment tools and difficulties in establishing multidisciplinary teams that include cardiologists. The experts subsequently provided practical recommendations to improve cardio-oncology care for patients with PCa receiving ADT, such as simplifying cardiovascular risk assessment, individualising treatment based on CVD risk categories, establishing multidisciplinary teams and referral networks and fostering active patient engagement. A streamlined cardiovascular risk-stratification tool and a referral/management guide were developed for seamless integration into urologists' practices and presented herein. The PCCV Expert Network agreed that currently available evidence indicates that GnRH antagonists are associated with a lower risk of CVD than that of GnRH agonists and that GnRH antagonists are preferred for patients with PCa and a high CVD risk. CONCLUSION: In summary, this article provides insights and guidance to improve management for patients with PCa undergoing ADT.

RESUMO

BACKGROUND: Extracellular vesicles (EVs), including microvesicles, hold promise for the management of bladder urothelial carcinoma (BLCA), particularly because of their utility in identifying therapeutic targets and their diagnostic potential using easily accessible urine samples. Among the transmembrane glycoproteins highly enriched in cancer-derived EVs, tissue factor (TF) and CD147 have been implicated in promoting tumor progression. In this in vitro study, we explored a novel approach to impede cancer cell migration and metastasis by simultaneously targeting these molecules on urothelial cancer-derived EVs. METHODS: Cell culture supernatants from invasive and non-invasive bladder cancer cell lines and urine samples from patients with BLCA were collected. Large, microvesicle-like EVs were isolated using sequential centrifugation and characterized by electron microscopy, nanoparticle tracking analysis, and flow cytometry. The impact of urinary or cell supernatant-derived EVs on cellular phenotypes was evaluated using cell-based assays following combined treatment with a specific CD147 inhibitor alone or in combination with a tissue factor pathway inhibitor (TFPI), an endogenous anticoagulant protein that can be released by low-molecular-weight heparins. RESULTS: We observed that EVs obtained from the urine samples of patients with muscle-invasive BLCA and from the aggressive bladder cancer cell line J82 exhibited higher TF activity and CD147 expression levels than did their non-invasive counterparts. The shedding of GFP-tagged CD147 into isolated vesicles demonstrated that the vesicles originated from plasma cell membranes. EVs originating from invasive cancer cells were found to trigger migration, secretion of matrix metalloproteinases (MMPs), and invasion. The same induction of MMP activity was replicated using EVs obtained from urine samples of patients with invasive BLCA. EVs derived from cancer cell clones overexpressing TF and CD147 were produced in higher quantities and exhibited a higher invasive potential than those from control cancer cells. TFPI interfered with the effect when used in conjunction with the CD147 inhibitor, further suppressing homotypic EV-induced migration, MMP production, and invasion. CONCLUSIONS: Our findings suggest that combining a CD147 inhibitor with low molecular weight heparins to induce TFPI release may be a promising therapeutic approach for urothelial cancer management. This combination can potentially suppress the tumor-promoting actions of cancer-derived microvesicle-like EVs, including collective matrix invasion.


Small particles or vesicles released by cancer cells into their surroundings have the potential to stimulate the spread and growth of cancer cells. In this study, we focused on two specific molecules presented by these cancer cell-derived vesicles that could play a role in promoting the dissemination of cancer cells: a protein related to blood clotting and a protein on the cell surface.We found that large vesicles from bladder cancer cells that have the ability to spread had higher levels of these proteins than vesicles from nonspreading cancer cells. We also found that the former could make cancer cells move about more, produce more of a substance that helps cancer cells spread, and invade other tissues.To counteract the cancer-promoting actions of these vesicles, we examined the impact of combining a naturally occurring anticlotting protein that can be released by medications derived from heparin with an inhibitor targeting the cancer cell surface protein. We found that this combination stopped the vesicles from helping cancer cells move about more, produce more of the spreading substance, and invade other tissues.This approach of simultaneously targeting the two protein molecules present on cancer cell-derived vesicles might be a new way to treat bladder cancer.

RESUMO

WHAT IS THIS SUMMARY ABOUT?: This summary describes the results from an additional (or post hoc) analysis of the TITAN study. The TITAN study looked at whether the prostate cancer treatment apalutamide could be used to treat individuals with metastatic castration-sensitive prostate cancer (or mCSPC). A total of 1052 participants with mCSPC were included in the TITAN study. Treatment with apalutamide was compared with treatment with placebo. All participants received androgen deprivation therapy (or ADT), which is a type of hormone therapy that has been part of the main treatment for mCSPC for many years. The results showed that apalutamide plus ADT increased the length of time that participants remained alive compared with placebo plus ADT. Apalutamide plus ADT also controlled the growth of the cancer for a longer length of time compared with placebo plus ADT. Additionally, participants who received apalutamide plus ADT experienced a greater reduction in the blood levels of prostate-specific antigen (or PSA), called a deep PSA decline, compared with those who received placebo plus ADT. An additional (or post hoc) analysis was carried out to understand whether a decrease in blood PSA levels, in response to treatment, was associated with improved outcomes, including longer survival time. WHAT WERE THE RESULTS OF THE ADDITIONAL ANALYSIS?: In participants who received apalutamide plus ADT, a deep PSA decline in response to treatment was associated with longer survival time and improved outcomes. WHAT DO THESE RESULTS MEAN FOR INDIVIDUALS WITH MCSPC?: These results demonstrate that individuals with mCSPC can benefit from treatment with apalutamide plus ADT. The association seen between deep PSA decline and the longer survival time and improved outcomes highlights how PSA measurements can be used to help monitor cancer disease evolution in response to treatment. Monitoring PSA levels will assist doctors and other healthcare professionals to understand how effectively a treatment is working for a patient and to tailor their treatment approach to improve PSA decline.

RESUMO

A 67-year-old female patient with a muscle-invasive, non-metastatic urothelial bladder cancer (UC) (pT2 G3 cN0 cM0) developed metachronous metastases within 6 months after radical cystectomy with ileal conduit urinary diversion. After a good primary response to platinum-based chemotherapy, treatment was switched to the immune checkpoint inhibitor (ICI) pembrolizumab due to progressive disease. Subsequently the patient underwent selective internal radiotherapy (SIRT) of the liver and received vinflunine as well as a re-challenge with pembrolizumab. Two years after the initial diagnosis, rapid disease progression ultimately led to a switch to 5th line therapy with enfortumab vedotin (EV), which had only been approved in the United States at that time. The antibody-drug conjugate was well tolerated by the patient after dose reduction to 1.0 mg/ kg body weight. Simultaneous irradiation of newly occurring precardiac, hepatic and cerebral metastases were necessary. After 10 months of therapy with EV, tumour regression was observed accompanied with good symptom control. The presented case illustrates the efficacy and tolerability of EV in a heavily pre-treated patient with metastatic UC (mUC).

RESUMO

INTRODUCTION: In countries characterized by a centralization of therapy management, patients with penile cancer (PeCa) have shown improvements in guideline adherence and ultimately, improved carcinoma-specific survival. Germany and Austria (G + A) have no state-regulated centralization of PeCa management, and the perspectives of urological university department chairs (UUDCs) in these countries, who act as drivers of professional and political developments, on this topic are currently unknown. METHODS: Surveys containing 36 response options, including specific questions regarding perspectives on PeCa centralization, were sent to the 48 UUDC in G + A in January 2023. In addition to analyzing the responses, closely following the CROSS checklist, a modeling of the real healthcare situation of in-house PeCa patients in G + A was conducted. RESULTS: The response rate was 75% (36/48). 94% and 89% of the UUDCs considered PeCa centralization meaningful and feasible in the medium term, respectively. Among the UUDCs, 72% estimated centralization within university hospitals as appropriate, while 28% favored a geographically oriented approach. Additionally, 97% of the UUDCs emphasized the importance of bridging the gap until implementation of centralization by establishing PeCa second-opinion portals. No country-specific differences were observed. The median number of in-house PeCa cases at the university hospitals in G + A was 13 (interquartile range: 9-26). A significant positive correlation was observed between the annual number of in-house PeCa cases at a given university hospital and the perspective of the UUDCs that centralization as meaningful by its UUDC (0.024). Under assumptions permissible for modeling, the average number of in-house PeCa cases in academic hospitals in G + A was approximately 30 times higher than in nonacademic hospitals. CONCLUSION: This study provides the first data on the perspectives of UUDCs in G + A concerning centralization of PeCa therapy management. Even without state-regulated centralization in G + A, there is currently a clear focusing of PeCa treatments in university hospitals. Further necessary steps toward a structured PeCa centralization are discussed in this manuscript.

RESUMO

BACKGROUND: Whether disease burden in patients with metastatic castration-sensitive prostate cancer (mCSPC) predicts treatment outcomes is unknown. We assessed apalutamide treatment effect in TITAN patients with mCSPC by disease volume, metastasis number and timing of metastasis presentation. METHODS: These protocol-defined and post hoc analyses of the phase III randomised TITAN study evaluated clinical outcomes in patients receiving 240 mg/day apalutamide (n = 525) or placebo (n = 527) plus androgen-deprivation therapy (ADT). Subgroups were defined by volume (high: visceral and ≥1 bone metastases or ≥4 bone lesions with ≥1 beyond vertebral column/pelvis), development of metastases per conventional imaging (synchronous: at initial diagnosis; metachronous: after localised disease) and oligometastases (≤5 bone-only metastases) or polymetastases (>5 in bone ± other locations or ≤5 in bone plus other locations). Overall survival (OS), radiographic or second progression-free survival, and time to prostate-specific antigen progression or castration resistance were assessed using Cox proportional hazards models. RESULTS: Of 1052 patients, 63%, 81%, 54%, 27%, 5.7%, and 8.0% had high-volume, synchronous, synchronous/high-volume, synchronous/low-volume, metachronous/high-volume, and metachronous/low-volume disease, respectively. The OS benefit favoured apalutamide plus ADT versus ADT alone in synchronous/high-volume (hazard ratio = 0.68 [95% confidence interval: 0.53-0.87]; p = 0.002), synchronous/low-volume (0.65 [0.40-1.05]; p = 0.08), metachronous/high-volume (0.69 [0.33-1.44]; p = 0.32) and metachronous/low-volume (0.22 [0.09-0.55]; p = 0.001) subgroups. Apalutamide improved other clinical outcomes regardless of subgroup, with similar safety profiles. Most favourable outcomes were observed in oligometastatic disease. CONCLUSION: TITAN patients derived a robust benefit with apalutamide plus ADT regardless of disease volume and timing of metastasis presentation without differences in safety, supporting early apalutamide intensification in mCSPC. CLINICAL TRIAL REGISTRATION: NCT02489318.

RESUMO

BACKGROUND: The European Association of Urology guidelines include the lutetium-177 (177Lu) PSMA-617 prostate-specific membrane antigen (PSMA) ligand as a therapy option for metastatic castration-resistant prostate cancer (mCRPC). A major challenge in clinical practice is to pursue a personalized treatment approach based on robust predictive biomarkers. OBJECTIVE: To assess the performance of 177Lu PSMA in real-world practice and to elaborate clinical biomarkers for evaluating treatment responses. DESIGN, SETTING, AND PARTICIPANTS: We conducted a retrospective observational study including 233 patients with mCRPC treated with 177Lu PSMA in eight high-volume European centers. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Baseline characteristics and clinical parameters during and after 177Lu PSMA treatment were documented. Correlations to treatment response were analyzed using χ2 and log-rank tests, with differences between groups with and without disease progression calculated using a Mann-Whitney U test. Univariate and multivariate-adjusted hazard ratios (HRs) were measured using Cox proportional hazards models. RESULTS AND LIMITATIONS: A prostate-specific antigen (PSA) decrease of ≥30% was observed in 41.7%, 63.5%, and 77.8% of patients after the first, second, and third treatment cycle, respectively. Restaging performed via PSMA positron emission tomography-computed tomography revealed that 33.7% of patients had an imaging-based response, including two patients with a complete response, while 13.4% had stable disease. The median time to progression was 5 mo and the median time until the start of a consecutive antineoplastic therapy was 8.5 mo. Of importance, a PSA decrease ≥30% after the first two cycles of 177Lu PSMA (1 cycle: p = 0.0003; 2 cycles: p = 0.004), absolute PSA after the first three cycles (1 cycle: p = 0.011; 2 cycles: p = 0.0005; 3 cycles: p = 0.002), and a PSA doubling time >6 mo (p = 0.009) were significantly correlated to treatment response. Furthermore, gamma-glutamyl transferase ≤31 U/L at the start of 177Lu PSMA therapy was correlated with 1.5 times higher risk of progression for patients without but not with visceral metastases (p = 0.046). CONCLUSIONS: 177Lu PSMA is an effective treatment option in mCRPC in the real-world setting. A PSA decrease ≥30% after the first two cycles is an early marker of response that can be easily implemented in clinical practice. PATIENT SUMMARY: 177Lu PSMA is a radioactive agent approved for treatment of advanced prostate cancer. We reviewed its use outside of clinical trials for patients treated at eight European centers. We found that 177Lu PSMA is an effective treatment option in real-world practice. A PSA (prostate-specific antigen) decrease of ≥30% after the first two therapy cycles is an early indicator of response to treatment and can be used in personalizing treatments for patients.

RESUMO

CONTEXT: Symptomatic lymphocele (sLC) occurs at a frequency of 2-10% after robot-assisted radical prostatectomy (RARP) with pelvic lymph node dissection (PLND). Construction of bilateral peritoneal interposition flaps (PIFs) subsequent to completion of RARP + PLND has been introduced to reduce the risk of lymphocele, and was initially evaluated on the basis of retrospective studies. OBJECTIVE: To conduct a systematic review and meta-analysis of only randomized controlled trials (RCTs) evaluating the impact of PIF on the rate of sLC (primary endpoint) and of overall lymphocele (oLC) and Clavien-Dindo grade ≥3 complications (secondary endpoints) to provide the best available evidence. EVIDENCE ACQUISITION: In accordance with the Preferred Reporting Items for Meta-Analyses statement for observational studies in epidemiology, a systematic literature search using the MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE databases up to February 3, 2023 was performed to identify RCTs. The risk of bias (RoB) was assessed using the revised Cochrane RoB tool for randomized trials. Meta-analysis used random-effect models to examine the impact of PIF on the primary and secondary endpoints. EVIDENCE SYNTHESIS: Four RCTs comparing outcomes for patients undergoing RARP + PLND with or without PIF were identified: PIANOFORTE, PerFix, ProLy, and PLUS. PIF was associated with odds ratios of 0.46 (95% confidence interval [CI] 0.23-0.93) for sLC, 0.51 (95% CI 0.38-0.68) for oLC, and 0.41 (95% CI 0.21-0.83) for Clavien-Dindo grade ≥3 complications. Functional impairment resulting from PIF construction was not observed. Heterogeneity was low to moderate, and RoB was low. CONCLUSIONS: PIF should be performed in patients undergoing RARP and simultaneous PLND to prevent or reduce postoperative sLC. PATIENT SUMMARY: A significant proportion of patients undergoing prostate cancer surgery have regional lymph nodes removed. This part of the surgery is associated with a risk of postoperative lymph collections (lymphocele). The risk of lymphocele can be halved via a complication-free surgical modification called a peritoneal interposition flap.

RESUMO

Purpose: To report the use of high-dose-rate (HDR) interventional radiotherapy (brachytherapy, IRT) as a salvage treatment for macroscopic histologically confirmed local relapse of prostatic cancer after prostatectomy and subsequent external irradiation. Material and methods: A retrospective study of patients with prostate adenocarcinoma, treated with HDR-IRT for an isolated local relapse after prostatectomy and external irradiation at our institution (2010-2020). Treatment results and treatment related-toxicity were recorded. Clinical outcomes were analyzed. Results: Ten patients were identified. The median age was 63 years (range, 59-74 years), and the median follow-up time was 34 months (range, 10-68 months). Four patients had a biochemical relapse, and the mean time to prostate specific antigen (PSA) increase was 13 months. One-year biochemical failure-free survival (bFFS), 3-year bFFS, and 4-year bFFS were 80%, 60%, and 60%, respectively. Most of the treatment-related toxicities were grade 1-2. Two patients experienced grade 3 late genitourinary toxicity. Conclusions: HDR-IRT seems to be an effective treatment option showing acceptable toxicity for prostate cancer patients with isolated macroscopic histologically confirmed local relapse after prostatectomy and subsequent external irradiation.

RESUMO

INTRODUCTION: Urine cytology (UC) is a recommended tool for the diagnosis of urothelial malignancies. Thus far, no specific recommendations regarding the role of washing cytology (WC) have been included in the guidelines. The goal of our study was to analyse the relationship between the histology of transurethrally (transurethral resection of the bladder [TURBT]) resected bladder tumours (BCa) and intraoperative UC or WC findings. MATERIALS AND METHODS: Five hundred consecutive primary TURBT cases conducted between November 2010 and 2015 at our department of the University Hospital Luebeck were retrospectively analysed. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) of UC and WC were evaluated to detect BCa. Multivariate logistic regression models were fit to further examine associations between patient- and tumour-related factors and a bladder UC or WC positive for BCa. RESULTS: UC was performed in 297 patients, WC in 294 patients, and both in 261 patients. Sensitivity was 50.7% in UC, 58.1% in WC, and 62.1% for both tests combined. Specificity was 97.8% for UC, 98.0% for WC, and 96.4% for the combined tests. PPV was 98.0% for UC, 98.1% for WC, and 97.2% for combined tests. NPV was 47.8% for UC, 54.5% for WC, and 55.9% for the combined tests. The multivariate analyses revealed no association between positive UC or WC results and subsequent radical cystectomy (UC OR 1.35, 95% CI: 0.3-5.7; WC OR 2.0, 95% CI: 0.4-11.4). Neither UC nor WC was significantly correlated with local recurrence. CONCLUSIONS: Cytologic testing is an important diagnostic tool in BCa detection, showing acceptable sensitivity of around 60% and excellent specificity of over 90%. UC and WC present similar sensitivity. Our results advocate, however, against cytologic testing during primary TURBT, especially with regard to the lack of value in assessing the risk of recurrence. The clinical benefit of taking both types of samples at once is minimal. Furthermore, intraoperative WC collection does not reliably predict subsequent cystectomies.

RESUMO

BACKGROUND: Initial TRITON2 (NCT02952534) results demonstrated the efficacy of rucaparib 600 mg BID in patients with metastatic castration-resistant prostate cancer (mCRPC) associated with a BRCA1 or BRCA2 (BRCA) or other DNA damage repair (DDR) gene alteration. OBJECTIVE: To present the final data from TRITON2. DESIGN, SETTING, AND PARTICIPANTS: TRITON2 enrolled patients with mCRPC who had progressed on one or two lines of next-generation androgen receptor-directed therapy and one taxane-based chemotherapy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was objective response rate (ORR; as per the modified Response Evaluation Criteria in Solid Tumor Version 1.1/Prostate Cancer Clinical Trials Working Group 3 criteria in patients with measurable disease by independent radiology review [IRR]); prostate-specific antigen (PSA) response rate (≥50% decrease from baseline [PSA50]) was a key secondary endpoint. RESULTS AND LIMITATIONS: As of July 27, 2021 (study closure), TRITON2 had enrolled 277 patients, grouped by mutated gene: BRCA (n = 172), ATM (n = 59), CDK12 (n = 15), CHEK2 (n = 7), PALB2 (n = 11), or other DDR gene (Other; n = 13). ORR by IRR was 46% (37/81) in the BRCA subgroup (95% confidence interval [CI], 35-57%), 100% (4/4) in the PALB2 subgroup (95% CI, 40-100%), and 25% (3/12) in the Other subgroup (95% CI, 5.5-57%). No patients within the ATM, CDK12, or CHEK2 subgroups had an objective response by IRR. PSA50 response rates (95% CI) in the BRCA, PALB2, ATM, CDK12, CHEK2, and Other subgroups were 53% (46-61%), 55% (23-83%), 3.4% (0.4-12), 6.7% (0.2-32%), 14% (0.4-58%), and 23% (5.0-54%), respectively. CONCLUSIONS: The final TRITON2 results confirm the clinical benefit and manageable safety profile of rucaparib in patients with mCRPC, including those with an alteration in BRCA or select non-BRCA DDR gene. PATIENT SUMMARY: Almost half of TRITON2 patients with BRCA-mutated metastatic castration-resistant prostate cancer had a complete or partial tumor size reduction with rucaparib; clinical benefits were also observed with other DNA damage repair gene alterations.

RESUMO

BACKGROUND: Currently, 959 men in Germany and 67 in Austria are diagnosed with penile cancer each year, with an increase of approximately 20% in the last decade [RKI 2021, Statcube.at 2023]. Despite the rising incidence, the number of cases per hospital remains low. The median annual number of penile cancer cases at university hospitals in the DACH region was 7 patients (IQR 5-10) in 2017 [E-PROPS group 2021]. The compromised institutional expertise due to low case numbers is compounded with inadequate adherence to penile cancer guidelines, as shown in several studies. The centralization, which is rigorously implemented in countries such as the UK, enabled a significant increase in organ-preserving primary tumor surgery and stage-adapted lymphadenectomies, as well as improved patient survival in cases of penile cancer, resulting in a claim for a similar centralization in Germany and Austria. The aim of this study was to determine the current effects of case volume on penile cancer related treatment options at university hospitals in Germany and Austria. MATERIALS AND METHODS: In January 2023, a survey was sent to the heads of 48 urological university hospitals in Germany and Austria, including questions regarding case volume in 2021 (total number of inpatient and penile cancer cases), treatment options for primary tumors and inguinal lymphadenectomy (ILAE), the availability of a designated penile cancer surgeon, and the professional responsibility for systemic therapies in penile cancer. Correlations and differences related to case volume were statistically analyzed without adjustments. RESULTS: The response rate was 75% (n=36/48). In total, 626 penile cancer patients were treated at the 36 responding university hospitals in 2021, representing approximately 60% of the expected incidence in Germany and Austria. The annual median total number of cases was 2807 (IQR 1937-3653), and for penile cancer, it was 13 (IQR 9-26). There was no significant correlation between the total inpatient and penile cancer caseloads (p=0.34). The number of organ-preserving therapy procedures for the primary tumor, the availability of modern ILAE procedures, the presence of a designated penile cancer surgeon, and the responsibility for systemic therapies were not significantly influenced by the total inpatient or penile cancer case volume of the treating hospitals, regardless of whether the case volumes were dichotomized at the median or upper quartile. No significant differences between Germany and Austria were observed. CONCLUSION: Despite a significant increase in the annual number of penile cancer cases at university hospitals in Germany and Austria compared to 2017, we found no case volume-related effects on structural quality with respect to penile cancer therapy. In the light of the proven benefits of centralization, we interpret this result as an argument for the necessity of establishing nationally organized penile cancer centers with even higher case volumes compared to the status quo, in light of the proven benefits of centralization.

RESUMO

Due to demographic change associated with an increase in patient numbers as well as the existing shortage of medical personnel, the German healthcare system will face a major challenge in patient care. In order to maintain high-quality patient care at a high level, the digitisation of urology should be driven forward promptly and forcefully as digital applications such as online appointment scheduling, video consultations, digital health applications (DiGAs) and others could significantly improve treatment efficiency. The long-planned introduction of the electronic patient record (ePA) will hopefully accelerate this process, and medical online platforms could also become a permanent part of new treatment methods, which could emerge from the urgently needed structural change towards more digital medicine, including questionnaire-based telemedicine. This transformation, which, already today, is urgently needed in the healthcare system, must be demanded and promoted by service providers, but also by policymakers and administration, in order to achieve the positive development of digitisation in (urological) medicine.

RESUMO

Drug-based hormonal ablation is an essential component of therapy in hormone-sensitive advanced prostate cancer and as a backbone in castration resistance. LHRH agonists are among the most widely used medicinal products. Since these are usually given for life, therapy management is very important. Common side-effects typical of the substance class, such as weight gain, cardiovascular problems, hot flushes, erectile dysfunction or osteoporosis, can significantly reduce patients' quality of life and increase morbidity and mortality. This endangers adherence and, hence, treatment success. This paper provides an overview of how to deal with side-effects during LHRH therapy based on current data and practical experience.

RESUMO

PURPOSE: Radiomics in uro-oncology is a rapidly evolving science proving to be a novel approach for optimizing the analysis of massive data from medical images to provide auxiliary guidance in clinical issues. This scoping review aimed to identify key aspects wherein radiomics can potentially improve the accuracy of diagnosis, staging, and extraprostatic extension in prostate cancer (PCa). METHODS: The literature search was performed on June 2022 using PubMed, Embase, and Cochrane Central Controlled Register of Trials. Studies were included if radiomics were compared with radiological reports only. RESULTS: Seventeen papers were included. The combination of PIRADS and radiomics score models improves the PIRADS score reporting of 2 and 3 lesions even in the peripheral zone. Multiparametric MRI-based radiomics models suggest that by simply omitting diffusion contrast enhancement imaging in radiomics models can simplify the process of analysis of clinically significant PCa by PIRADS. Radiomics features correlated with the Gleason grade with excellent discriminative ability. Radiomics has higher accuracy in predicting not only the presence but also the side of extraprostatic extension. CONCLUSIONS: Radiomics research on PCa mainly uses MRI as an imaging modality and is focused on diagnosis and risk stratification and has the best future possibility of improving PIRADS reporting. Radiomics has established its superiority over radiologist-reported outcomes but the variability has to be taken into consideration before translating it to clinical practice.

RESUMO

Few prognostic factors have been identified in patients with metastatic urothelial carcinoma (mUC) treated with immune checkpoint inhibitors (ICIs). The Lung Immune Prognostic Index (LIPI) was associated with clinical outcomes for ICIs in several tumor types. We aim to assess the value of the LIPI in patients with mUC treated with ICIs. A retrospective ICI cohort and a validation cohort (SAUL cohort) included, respectively, patients with mUC treated with ICI in 8 European centers (any line) and patients treated with atezolizumab in a second or further line. A chemotherapy-only cohort was also analyzed. The LIPI score was based on 2 factors, derived neutrophils/(leukocytes minus neutrophils) ratio (dNLR) > 3 and lactate dehydrogenase > upper limit of normal, and defined 3 prognostic groups. The association of LIPI with progression-free survival (PFS) and overall survival (OS) was assessed. In the ICI and SAUL cohorts, 137 and 541 patients were respectively analyzed. In the ICI cohort, mPFS and mOS were 3.6 mo (95% CI; 2.6-6.0) and 13.8 mo (95% CI; 11.5-23.2) whereas in the SAUL cohort the mPFS and mOS were 2.2 mo (95% CI; 2.1-2.3) and 8.7 mo (95% CI; 7.8-9.9) respectively. The LIPI classified the population of these cohorts in good (56%; 52%), intermediate (35%; 36%) and poor (9%; 12%) prognostic groups (values for the ICI and SAUL cohorts respectively). Poor LIPI was associated with a poorer OS in both cohorts: hazard ratio (HR) for the ICI cohort = 2.69 (95% CI; 1.24-5.84, p = 0.035); HR = 2. 89 for the SAUL cohort (CI 95%: 1.93-4.32, p < 0.0001). Similar results were found in the chemo cohort. The LIPI score allows to identify different subgroups in patients with good prognostis according to the Bellmunt score criteria, with a subset of patients with poorer outcomes having an mOS of 3.7 mo compared to the good and intermediate LIPI subgroups with mOS of 17.9 and 7.4 mo, respectively. The LIPI score was associated with survival in mUC patients treated by ICIs. Future prospective studies will be required to test the combination of Bellmunt score and the LIPI score as a more accurate prognosis tool.

RESUMO

(1) Background: Prostate cancer (PCa) is the most frequently diagnosed cancer in men. Wide application of prostate specific antigen test has historically led to over-treatment, starting from excessive biopsies. Risk calculators based on molecular and clinical variables can be of value to determine the risk of PCa and as such, reduce unnecessary and invasive biopsies. Urinary molecular studies have been mostly focusing on sampling after initial intervention (digital rectal examination and/or prostate massage). (2) Methods: Building on previous proteomics studies, in this manuscript, we aimed at developing a biomarker model for PCa detection based on urine sampling without prior intervention. Capillary electrophoresis coupled to mass spectrometry was applied to acquire proteomics profiles from 970 patients from two different clinical centers. (3) Results: A case-control comparison was performed in a training set of 413 patients and 181 significant peptides were subsequently combined by a support vector machine algorithm. Independent validation was initially performed in 272 negative for PCa and 138 biopsy-confirmed PCa, resulting in an AUC of 0.81, outperforming current standards, while a second validation phase included 147 PCa patients. (4) Conclusions: This multi-dimensional biomarker model holds promise to improve the current diagnosis of PCa, by guiding invasive biopsies.

RESUMO

Mutations in the BRCA1 and BRCA2 tumour suppressor genes are associated with prostate cancer risk; however, optimal screening protocols for individuals with these mutations have been a subject of debate. Several prospective studies of prostate cancer incidence and screening among BRCA1/2 mutation carriers have indicated at least a twofold to fourfold increase in prostate cancer risk among carriers of BRCA2 mutations compared with the general population. Moreover, BRCA2 mutations are associated with more aggressive, high-grade disease characteristics at diagnosis, more aggressive clinical behaviour and greater prostate cancer-specific mortality. The risk for BRCA1 mutations seems to be attenuated compared with BRCA2. Prostate-specific antigen (PSA) measurement or prostate magnetic resonance imaging (MRI) alone is an imperfect indicator of clinically significant prostate cancer; therefore, BRCA1/2 mutation carriers might benefit from refined risk stratification strategies. However, the long-term impact of prostate cancer screening is unknown, and the optimal management of BRCA1/2 carriers with prostate cancer has not been defined. Whether timely localized therapy can improve overall survival in the screened population is uncertain. Long-term results of prospective studies are awaited to confirm the optimal screening strategies and benefits of prostate cancer screening among BRCA1/2 mutation carriers, and whether these approaches ultimately have a positive impact on survival and quality of life in these patients.
