RESUMO

Radical cystectomy is the current treatment of choice for patients with BCG-unresponsive non-muscle invasive bladder tumor (NMIBC). However, the high comorbidity of this surgery and its effects on the quality of life of patients require the investigation and implementation of bladder-sparing treatment options. These must be evaluated individually by the uro-oncology committee based on the characteristics of the BCG failure, type of tumor, patient preferences and treatment options available in each center. Based on FDA-required oncologic outcomes (6-month complete response rate for CIS: 50%; duration of response in responders for CIS and papillary: 30% at 12 months and 25% at 18 months), there is not currently a strong preference for one treatment over another, although the intravesical route seems to offer less toxicity. This work summarizes the evidence on the management of BCG-unresponsive NMIBC based on current scientific evidence and provides consensus recommendations on the most appropriate treatment.

RESUMO

OBJECTIVE: The aim of this review is to summarize the current evidence and future perspectives of bladder-sparing treatment for MIBC. METHODS: A non-systematic literature search in Medline/Pubmed was performed in October 2023 with the following keywords "bladder cancer", "bladder-sparing", "trimodal therapy", "chemoradiation", "biomarkers", "immunotherapy", "neoadjuvant chemotherapy", "radiotherapy". RESULTS: Urology guidelines recommend radical cystectomy as the standard curative treatment for muscle-invasive urothelial bladder cancer, reserving radiotherapy for patients who are unfit or who want to preserve their bladder. Given the morbidity and mortality of cystectomy and its impact on quality of life and bladder function, modern oncologic therapies are increasingly oriented toward organ preservation and maximizing functional outcomes while maintaining treatment efficacy. Trimodal therapy, which incorporates maximal transurethral resection followed by radiotherapy with concurrent radiosensitizing chemotherapy, is an effective regimen for bladder function preservation in well-selected patients. Despite the absence of comparative data from randomized trials, the two approaches seem to provide comparable oncologic outcomes. Studies are evaluating the expansion of eligibility criteria for trimodal therapy, the optimization of radiotherapy and immunotherapy delivery to further improve outcomes, and the validation of biomarkers to guide bladder preservation. CONCLUSIONS: Trimodal therapy has shown acceptable outcomes for bladder preservation; therefore, it provides a valid treatment option in well-selected patients.

RESUMO

INTRODUCTION: Renal trauma is the most common of urological trauma and accounts for up to 5% of all. The AAST scale is the most widely used to assess renal trauma. This study focuses on high-grade trauma, whose treatment has evolved towards a conservative approach, with techniques such as angioembolization. The aim is to describe the evolution in the management of high-grade renal trauma in all patients treated at La Paz University Hospital from 2001 to 2022. METHODS: A descriptive retrospective study was conducted on patients treated at the hospital. The study was divided into two periods (2001-2010 and 2011-2022). A total of 285 patients with renal trauma were collected, of which 54 were high grade. The main variable is the type of management, conservative (embolization) or interventional through nephrectomy. RESULTS: In the completed series, there was a decrease in radical nephrectomy in high-grade renal trauma from 50% to 13.8% over time, with an increase in embolization from 23,1% to 44,8%. In patients with isolated renal trauma, those treated with embolization increased from 28.6% to 69.2%, while those undergoing radical/partial nephrectomy decreased from 42.8% to 7.69%. CONCLUSION: The management of renal trauma has evolved over the years in our center. The number of patients treated by embolization has increased, while the number of complications and nephrectomies has decreased.

RESUMO

PURPOSE OF REVIEW: Pathologies of the prostate in men are one of the most prevalent clinical conditions today [1]. Specifically, pelvic inflammatory disease such as prostatitis can cause symptoms and syndromes different from urological ones, such as bowel or nervous system manifestations. This has a largely negative impact on the quality of life of patients. Therefore, it is convenient to know and update the information about the therapeutic approach to prostatitis, which is a challenge that involves different medical specialties. The aim of this article is to provide summarized and focused evidence to help in the therapeutic approach of patients with prostatitis. A computer-based search of the PubMed and Cochrane Library databases was used to perform a comprehensive literature review on prostatitis, with special interest in recent findings and latest therapeutic guideline recommendations. RECENT FINDINGS: Recent discoveries about the epidemiology and clinical classifications of prostatitis seem to incur in an increasingly individualized and directed management, with the aim of covering all the confluent factors in prostatic inflammatory pathology. In addition, the role of new drugs and combination with phytotherapy open up a range of new treatment possibilities, although future randomized studies will be necessary to better understand how to use all treatment modalities. Despite all the knowledge acquired about the pathophysiology of prostate diseases, and due to their interrelation with other pelvic systems and organs, there are still gaps that make it difficult for us to provide an optimal and standardized treatment in many of our patients. Being aware of the influence of all the factors potentially involved in prostate symptoms is crucial for a correct diagnosis and establishing an effective treatment plan.

RESUMO

Introducción: Las recidivas del carcinoma urotelial (CaU) en uretra o en el tracto urinario superior (TUS), tras una cistectomía radical (CR) son infrecuentes (4-6%), y su diagnóstico suele ocurrir en los 2 primeros años. Actualmente, no existen claras recomendaciones para la detección de recidivas en el urotelio remanente (UR), aunque se sabe que su detección precoz ofrece beneficios en la supervivencia. Nuestro objetivo es determinar el valor diagnóstico de la citología urinaria (CU) para la detección de recidivas en el UR y calcular su impacto como método de diagnóstico precoz en la supervivencia.Material y métodosRevisión retrospectiva de pacientes intervenidos de CR por CaU entre 2008-2016, con un seguimiento mayor de 24 meses.ResultadosSe incluyeron 142 pacientes. En una mediana de seguimiento de 68,5 meses, 9 pacientes (6,3%) presentaron recidivas en el UR (uretra: 4, TUS: 4, sincrónica: uno). La sensibilidad de la CU para el diagnóstico de recidivas en el TUS fue del 20% y la especificidad del 96%. No se encontraron diferencias significativas entre la supervivencia global y la supervivencia cáncer específica entre pacientes según el resultado de la CU.ConclusiónLas recidivas en el UR tras una CR son infrecuentes, y en nuestro estudio, hemos encontrado una baja sensibilidad para el diagnóstico de estas con CU. Por estas razones, no consideramos que la CU aporta información útil para el seguimiento de estos pacientes. (AU)


Introduction: Urethral or upper urinary tract (UUT) recurrence of urothelial carcinoma (UC) after radical cystectomy (RC) are rare (4-6%), and their diagnosis usually occurs within the first two years. Although it is known that its early detection offers benefit in terms of survival, currently there are no clear recommendations for the detection of recurrence in the remnant urothelium (RU). Our aim is to determine the diagnostic value of urinary cytology for the detection of recurrences in the RU and to estimate its impact as an early diagnostic method on survival.Material and methodsRetrospective review of patients who underwent RC for urothelial carcinoma between 2008-2016, with a follow-up of at least 24 months.ResultsThe study included 142 patients. In a median follow-up of 68.5 months, nine patients (6.3%) presented recurrences in the RU (urethra: four, UUT: four, synchronous: one). The sensitivity and specificity of urinary cytology for the diagnosis of UUT recurrences were 20% and 96%, respectively. No significant differences were found between overall survival and cancer-specific survival among patients according to the urinary cytology results.ConclusionRecurrences in the RU after RC are infrequent; our study has shown that urinary cytology offers a low sensitivity for their diagnoses. For these reasons, we do not consider that urinary cytology provides useful information for surveillance of these patients. (AU)

RESUMO

Introducción: En los últimos años, la vigilancia activa (VA) ha ganado popularidad como una opción segura y razonable para los pacientes con cáncer de próstata de bajo riesgo clínicamente localizado.ObjetivoResumir la información más reciente sobre el uso de resonancia magnética multiparamétrica (RMmp) en el contexto de la vigilancia activa (VA) para el tratamiento del cáncer de próstata (CaP).Adquisición de la evidenciaSe realizó una búsqueda en la literatura en inglés mediante PubMed hasta febrero de 2020. Se seleccionaron los artículos originales, metaanálisis, y revisiones sistemáticas más relevantes.Síntesis de la evidenciaLa gran importancia de la RMmp de la próstata en el contexto del diagnóstico del CaP es su capacidad de detectar lesiones cancerosas de alto grado que pueden haber sido omitidas en biopsias sistemáticas. Diversos estudios han demostrado que la RMmp tiene un rendimiento superior con respecto a los modelos basados en la clínica para identificar aquellos candidatos que se beneficiarán más de la VA. Aunque hay poca información sobre la RMmp de próstata durante el seguimiento de hombres en VA, existe la posibilidad de que ésta pueda mejorar significativamente los programas de VA, gracias a una selección más rigurosa de candidatos óptimos, una identificación más precisa de la progresión de la enfermedad, y una reducción en el número de biopsias. El objetivo de la reevaluación de los pacientes sometidos a VA es encontrar el momento en el que cambiar la estrategia hacia el tratamiento activo sea lo más efectivo.ConclusiónEl valor de la RMmp ha sido reconocido debido a su alto valor predictivo negativo (VPN) en la detección de lesiones de mayor grado en pacientes con CaP de bajo riesgo. Un mejor sistema de detección en las pruebas de imagen y un diagnóstico más exacto con RMmp podría reducir las clasificaciones erróneas en el diagnóstico inicial y durante el seguimiento, reduciendo así el número de biopsias.

Introduction: In recent years, active surveillance (AS) has gained popularity as a safe and reasonable option for patients with low-risk, clinically localized prostate cancer.ObjectiveTo summarize the latest information regarding the use of mpMRI in the setting of active surveillance (AS) for the management of prostate cancer (PCa).Evidence acquisitionA PubMed-based, English literature search was conducted through February 2020. We selected the most relevant original articles, meta-analyses and systematic reviews that could provide important information.Evidence synthesisThe great importance of mpMRI of the prostate in the setting of PCa diagnosis is its ability to visualize primarily high-grade cancerous lesions potentially missed on systematic biopsies. In several studies, mpMRI has shown an improved performance over clinically based models for identifying candidates which will benefit the most from AS. Although data on prostate mpMRI during follow-up of men under AS is sparse, it holds the probability to improve significantly AS programs by a more precise selection of optimal candidates, a more accurate identification of disease progression and a reduction in number of biopsies. The goal of reassessment of patients undergoing AS is to find the most effective moment to change attitude to active treatment.ConclusionThe value of mpMRI has been recognized due to its high negative predictive value (NPV) for lesion upgrading in low-risk PCa patients. The improvement in imaging detection, and precise diagnosis with mpMRI could reduce misclassifications at initial diagnosis and during follow-up, reducing the number of biopsies. (AU)

RESUMO

INTRODUCCIÓN: El tratamiento de elección para el cáncer vesical no músculo infiltrante (CVNMI) de alto riesgo es el bacilo de Calmette-Guérin (BCG). Sin embargo, cuando éste falla, el tratamiento indicado es la cistectomía radical. En los últimos años se están desarrollando ensayos con diversos fármacos para evitar esta cirugía en pacientes con fracaso a BCG. El objetivo de este artículo es llevar a cabo una puesta al día de los tratamientos en estudio para la preservación vesical en esta población de pacientes. Material y MÉTODOS: Revisión no sistemática, realizando una búsqueda en PubMed con los términos "Bladder cancer", "Non-muscle invasive bladder cancer", "NMIBC", "BCG", "BCG-refractory", "Mitomycin C", "MMC", "Hyperthermia", "Electromotive Drug Administration", "EMDA" Empleamos los buscadores clinicaltrials.gov y clinicaltrialsregister.eu para localizar ensayos clínicos. RESULTADOS: El único fármaco intravesical aprobado por la Food and Drug Administration (FDA) para carcinoma in situ (CIS) tras fracaso a BCG es la valrubicina. Recientemente la FDA ha aprobado pembrolizumab intravenoso, tras la publicación de los datos preliminares del estudio KEYNOTE-057. Atezolizumab ha demostrado unos resultados preliminares similares de eficacia. En las guías europeas se reconoce como alternativa únicamente la quimiohipertermia inducida por microondas y EMDA-MMC (electromotive drug administration). Otras alternativas en investigación son los taxanos y la gemcitabina, solos o en combinación, los virus recombinantes y la quimiohipertermia intravesical asistida por dispositivos. CONCLUSIONES: Los resultados de los nuevos fármacos son prometedores, con gran número de ensayos en marcha. Conocer los mecanismos de resistencia a BCG es imprescindible para la exploración de nuevas alternativas terapéuticas


INTRODUCTION: The treatment of choice for high-risk non-muscle invasive bladder cancer (NMIBC) is bacillus Calmette-Guérin (BCG). However, when this fails, the indicated treatment is radical cystectomy. In recent years, trials are being developed with various drugs to avoid this surgery in patients with BCG failure. The aim of this article is to update the treatments under study for bladder preservation in this patient population. MATERIAL AND METHODS: Non-systematic review, searching PubMed with the terms "Bladder cancer", "Non-muscle invasive bladder cancer", "NMIBC", "BCG", "BCG-refractory", "Mitomycin C", "MMC", "Hyperthermia", "Electromotive Drug Administration", "EMDA" We used the search engines clinicaltrials.gov and clinicaltrialsregister.eu to find clinical trials. RESULTS: The only intravesical drug approved by the Food and Drug Administration (FDA) for carcinoma in situ (CIS) after failure to BCG is valrubicin. Recently, the FDA has approved intravenous pembrolizumab, following the publication of preliminary data from the KEYNOTE-057 study. Atezolizumab has demonstrated similar preliminary efficacy results. Only microwave-induced chemohyperthermia and EMDA-MMC (electromotive drug administration) are recognized as alternatives in European guidelines. Other options under investigation are taxanes and gemcitabine, alone or in combination, recombinant viruses and device-assisted intravesical chemohyperthermia. CONCLUSIONS: The results of new drugs are promising, with a large number of trials underway. Knowing the mechanisms of resistance to BCG is essential to explore new therapeutic options
