Correlación entre los índices estandarizados SUVmáx de la PET/TC con [68Ga]Ga-PSMA-I&T pre-prostatectomía radical y los resultados histopatológicos finales: un análisis en profundidad / Correlation between pre-radical prostatectomy Standardized SUVmax ratios detected on 68Ga-PSMA-I&T PET/CT and final histopathology outcomes: An in-depth analysis

Objetivo: Evaluar el potencial predictivo del valor máximo de captación estandarizada (SUVmáx) de los tumores intraprostáticos obtenidos en la PET/TC preoperatoria con [68Ga]Ga-PSMA-I&T (SUVT), así como sus relaciones con el SUVmáx en el hígado (SUVTLR) y la glándula parótida (SUVTPR) con respecto a los hallazgos histopatológicos. Material y métodos: Se evaluaron los datos de pacientes sometidos a prostatectomía radical (PR) por cáncer de próstata (CaP) en nuestra clínica entre los años 2017-2020. Se excluyeron aquellos pacientes con una neoplasia maligna secundaria, antecedentes de resección transuretral de próstata, tratamiento previo para CaP o que fueron sometidos a una PR de rescate. Dos especialistas en medicina nuclear con más de una década de experiencia cada uno revisaron las imágenes del estudio de cuerpo completo obtenidas con el mismo equipo, según protocolo, para obtener el consenso en cada lesión. Se estudiaron las relaciones entre edad, antígeno específico de la próstata (PSA), volumen de la próstata, estadio clínico, el grado de la clasificación de la Sociedad Internacional de Anatomía Patología Urológica (ISUP, por sus siglas en inglés) en la biopsia, el grupo de riesgo de D’amico, el volumen tumoral intraprostático identificado en la revisión histopatológica final de la muestra (HPTV) y el grado HP-ISUP. Se analizó la invasión de vesículas seminales (SVI), la invasión extracapsular (ECI), el margen quirúrgico positivo (PSM), SUVT, SUVTLR y SUVTPR. Resultados: La edad media de los 64 pacientes incluidos fue de 64,1±5,3 años. Se observó una correlación estadísticamente significativa entre los valores de SUVT, SUVTLR, SUVTPR y los parámetros del estadio histopatológico, como el grado ISUP de la biopsia, la clasificación de riesgo D’amico, HP-ISUP, HPTV (p<0,05). PSMATV, SUVT y SUVTLR fueron predictores estadísticamente significativos de invasión extracapsular, mientras que PSA, PSMATV y SUVTLR fueron predictores significativos de SVI (p<0,05)... (AU)

Objective: To evaluate the predictive potential of the maximum standardized uptake value (SUVmax) value of intraprostatic tumors derived from preoperative [68Ga]Ga-PSMA-I&T PET/CT (SUVT), and its ratios to SUVmax in the liver (SUVTLR) and parotid gland (SUVTPR) with respect to histopathological findings. Materials and methods: Data from patients who underwent radical prostatectomy (RP) for prostate cancer (PC) at our clinic between 2017-2020 were assessed. Patients with a secondary malignancy, a history of transurethral prostate resection, prior treatment for PC, or who received salvage RP were excluded. Whole-body images obtained using the same device, as per the guidelines, were reviewed by two nuclear medicine specialists with more than a decade of experience to reach a consensus for each lesion. The relationships between age, PSA, Prostate Volume, clinical T stage, biopsy International Society of Urological Pathology grade (ISUP), D’amico risk group, intraprostatic tumor volume (HPTV) identified in the final histopathological specimen review, HP-ISUP grade, seminal vesicle invasion (SVI), extracapsular invasion (ECI), positive surgical margine (PSM), SUVT, SUVTLR, and SUVTPR were analyzed. Results: The mean age of the 64 included patients was 64.1±5.3 y-o. A statistically significant correlation was found between SUVT, SUVTLR, SUVTPR values, and histopathologic stage parameters, such as biopsy ISUP, D’amico Risk Classification, HP-ISUP, HPTV (P<.05). PSMATV, SUVT, and SUVTLR were statistically significant predictors of extracapsular invasion, while PSA, PSMATV, and SUVTLR were significant predictors of SVI (P<.05). Conclusion: The standardized SUVT, SUVTLR, and SUVTPR values could be employed as noninvasive markers to assist in predicting postoperative histopathological findings, particularly ECI, SVI, and PSM.

Bilateral subgaleal hematoma after a robot-assisted radical prostatectomy: an uncommon complication / Hematoma subgaleal bilateral tras prostatectomía radical robótica: una complicación infrecuente

Robotassisted radical prostatectomy is a relatively recent technique. Its advantages include less invasiveness and better pain management, but has specific anesthesia requirements, such as steep Trendelenburg position and pneumoperitoneum. Mild complications are common, e.g., transient hypotension or soft tissue edema. We present a case of a 62 year old male who developed subgaleal hematoma associated with transient neurologic impairment after surgery. Jugular vein insufficiency was suspected as the most likely cause. The patient recovered fully.Robotassisted radical prostatectomy can be a challenging procedure due to the anesthesia requirements, but most complications are mild and transient. However, patients should be carefully assessed before surgery. We identified potential factors that may have led to this complication: the abnormal prolonged surgical time, the steep Trendelenburg, a nonassessed jugular vein insufficiency, and/or patient’s obesity.(AU)

La prostatectomía robótica radical es una técnica relativamente reciente. Sus ventajas son una menor invasividad y mejor control del dolor. Tiene algunas peculiaridades anestésicas, como Trendelenburg extremo y neumoperitoneo. Son frecuentes las complicaciones leves, como la hipotensión transitoria o el edema de partes blandas. Presentamos el caso de un varón de 62 años que desarrolló un hematoma subgaleal asociado a deterioro neurológico transitorio tras la intervención. Se sospechó como causa más probable una incompetencia venosa yugular. El paciente se recuperó completamente.La prostatectomía robótica radical puede ser un reto debido a los requisitos anestésicos, pero la mayoría de las complicaciones son leves y transitorias. No obstante, los pacientes deben ser estudiados cuidadosamente antes de la intervención. En este caso podemos encontrar varios factores que pueden haber influido, como el tiempo quirúrgico anormalmente prolongado, el Trendelenburg extremo, una insuficiencia de la vena yugular no evaluada y/o la obesidad del paciente.(AU)

Cirugía citorreductora en pacientes con cáncer de próstata oligometastásico. Revisión sistemática de la literatura científica / Cytoreductive surgery in patients with oligometastatic prostate cancer. systematic review of the scientific literature

Introducción La aparición de pruebas de imagen más específicas y sensibles, junto con el empleo cada vez más extendido de técnicas mínimamente invasivas, ha centrado el interés urológico sobre el cáncer de próstata oligometastásico. A pesar de esto, aún queda por determinar el manejo óptimo de esta patología. Objetivo Evaluar la eficacia y seguridad de la cirugía citorreductora en pacientes con cáncer de próstata oligometastásico. Adquisición de la evidencia Revisión sistemática de la literatura científica (01/01/2010-31/12/2021) en las bases de datos Medline, Embase, Cochrane Library, CINAHL, Scopus, Agencias de Evaluación de Tecnologías Sanitarias y ClinicalTrials.gov. Los descriptores utilizados han sido prostatectomy, prostatic neoplasm, radical prostatectomy, y los términos de búsqueda libre prostatectomy y oligomestastasicprostate. Los criterios de inclusión fueron estudios con pacientes con cáncer de próstata oligometastásico e intervenidos mediante prostatectomía radical citorreductora (CRP). Síntesis de la evidencia La revisión sistemática incluyó cuatro estudios observacionales, dos ensayos clínicos y dos series de casos, de calidad moderada. Los resultados observados sugieren un beneficio en cuanto a eficacia en aquellos pacientes oligometastásico sometidos a una cirugía de próstata citorreductora. Por otro lado, la mayoría de estos estudios revelan una reducción en el número de las complicaciones locales cuando se compara con los mejores tratamientos sistémicos. Conclusiones La cirugía citorreductora en este grupo de pacientes, es un procedimiento seguro que reduce las complicaciones locales, que ofrece resultados prometedores en cuanto a supervivencia. Hasta la fecha, la falta de ensayos prospectivos limita el papel de esta opción terapéutica a entornos experimentales (AU)

Introduction Interest in oligometastatic prostate cancer has spiked due to the emergence of new evidence regarding more specific and accurate imaging, and the wider use of minimally invasive techniques. Nevertheless, the optimal management of this pathology is yet to be determined. Objective Assess the efficacy and safety of cytoreductive surgery in patients suffering from oligometastatic prostate cancer. Evidence gathering Systematic review of the scientific literature (01/01/2010-31/12/2021) within the MedLine, Embase, Cochrane Library, Cinahl, Scopus, Spanish Healthcare Technology Assessment Agencies (AETS, Agencias de Evaluación de Tecnologías Sanitarias) and ClinicalTrials.gov databases. The keywords used were prostatectomy, prostatic neoplasm, radical prostatectomy; the free search terms were prostatectomy and oligometastaticprostate. The inclusion criteria comprised studies on patients with oligometastatic prostate cancer who had been operated on using radical cytoreductive prostatectomy. Evidence synthesis The systematic review included 4 observational studies, 2 clinical trials, and 2 case series, of moderate quality. The results observed suggest that oligometastatic prostate cancer patients who had undergone cytoreductive prostate surgery obtained a benefit in terms of efficacy. Conversely, the majority of these studies showed a reduction in the number of localized complications, when compared to the best systemic treatments. Conclusions Cytoreductive surgery in this group of patients is a safe procedure that reduces the incidence of localized complications and that presents promising results with regard to survival rates. To date, the lack of prospective trials limits the use of this therapeutic option to experimental environments (AU)

Preliminary results of the implementation of robotic radical prostatectomy in a major ambulatory surgery regimen.

OBJECTIVE: To report our initial experience with robotic radical prostatectomy as an outpatient procedure. MATERIAL AND METHODS: Retrospective analysis of patients who underwent RRP as MAS (Major Ambulatory Surgery) at our center between March 2021 and May 2022. We collected baseline patient characteristics, intraoperative outcomes and postoperative data (need for unplanned medical care and complications at one month after surgery). Oncologic characteristics at disease diagnosis (PSA, staging, ISUP, MRI) and postoperative pathologic outcomes were collected. RESULTS: We identified a total of 35 patients with an average age of 60,8 ± 6,88 years and a BMI of 27 ± 2,9 Kg/m2. All patients had a low anesthetic risk and 25.71% had undergone previous abdominal surgery. The surgical time was 151,66 ± 42,15 min and the average blood loss was 301,2 ± 184,38 mL. Two patients (5.7%) were admitted for one night and 7 patients (20%) consulted the emergency department in the following month, of which 3 (8.57%) were readmitted. We recorded one intraoperative complication, seven mild postoperative complications (Clavien I-II) and one severe complication (Clavien IIIb). The severe complication occurred on the eighth postoperative day and was not related to the procedure being ambulatory. CONCLUSION: The absence of serious complications in the immediate postoperative period supports RRP in MAS as a safe technique for selected patients.

Resultados preliminares de la implementación de la prostatectomía radical robótica en régimen de cirugía mayor ambulatoria / Preliminary results of the implementation of robotic radical prostatectomy in a major ambulatory surgery regimen

Objetivo Reportar nuestra experiencia inicial de prostatectomía radical robótica (PRR) en régimen ambulatorio. Material y métodos Análisis retrospectivo de los pacientes intervenidos de PRR en cirugía mayor ambulatoria (CMA) en nuestro centro entre marzo de 2021 y mayo de 2022. Recopilamos las características basales de los pacientes, los resultados intraoperatorios y los datos del postoperatorio (necesidad de asistencia médica no planificada y complicaciones al mes de la cirugía). Se recogieron las características oncológicas al diagnóstico de la enfermedad (PSA, estadificación, ISUP, RMN) y el resultado anatomopatológico tras la intervención. Resultados Identificamos un total de 35 pacientes, con una edad promedio de 60,8 ±6,88 años y un IMC de 27 ±2,9kg/m2. Todos presentaban un riesgo anestésico bajo y un 25,71% tenían alguna cirugía abdominal previa. El tiempo quirúrgico fue de 151,66 ±42,15 minutos y el sangrado promedio fue de 301,2 ±184,38mililitros. Dos pacientes (5,7%) ingresaron la primera noche de la cirugía y 7 pacientes (20%) consultaron en urgencias en el mes siguiente, de los cuales 3 (8,57%) reingresaron. Registramos una complicación intraoperatoria, 7 complicaciones postoperatorias leves (ClavienI-II) y una complicación grave (ClavienIIIb). La complicación grave transcurrió al octavo día postoperatorio y no tuvo relación con la ambulatorización del procedimiento. Conclusión La ausencia de complicaciones graves en el postoperatorio inmediato avala la PRR en régimen de CMA como una técnica segura dirigida a pacientes seleccionados (AU)

Controversias en radioterapia adyuvante en cáncer de próstata localizado

La elección del momento más adecuado para realizar radioterapia en el tratamiento del cáncer de próstata es controversial ya que puede ser realizada inmediatamente posterior a la prostatectomía o como tratamiento de rescate ante una recaída. En este artículo, se realiza una búsqueda del tema, se seleccionan los ensayos clínicos con mayor evidencia y se analizan los resultados. Si bien existe beneficio en la radioterapia adyuvante, este resultado no se encuentra en todos los pacientes y sí se asocia a mayor toxicidad genitourinaria tardía, por lo tanto, la clave está en la selección del tratamiento según el paciente específico.

The choice of the most appropriate time to perform radiotherapy in the treatment of prostate cancer is controversial since it can be performed immediately after prostatectomy or as rescue treatment in case of relapse. In this article, a search for the topic is carried out, the clinical trials with the greatest evidence are selected and the results are analyzed. Although there is benefit in adjuvant radiotherapy, this result is not found in all patients and it is associated with greater late genitoutinary toxicity, therefore, the key is in the selection of treatment according to the specific patient.

La prostatectomía radical retropúbica abierta es todavía una técnica quirúrgica bien establecida para el tratamiento del cáncer de próstata / Open retropubic radical prostatectomy: Still a well-established surgical technique for prostate cancer management

Introducción Las opciones de tratamiento quirúrgico del cáncer de próstata han experimentado cambios significativos gracias a la expansión de la robótica. Sin embargo, la prostatectomía radical retropúbica abierta (PRA) seguirá realizándose en aquellos entornos con limitaciones económicas o con escaso acceso a la robótica. El objetivo de este estudio fue determinar los resultados oncológicos a largo plazo, clasificar las tasas de complicaciones y examinar las tasas de recuperación temprana de la continencia en pacientes tratados con PRA. Métodos Identificamos a todos los pacientes sometidos a PRA en nuestra institución entre 2000 y 2020. Se utilizó un pad test (prueba de la compresa) estandarizado para determinar las tasas de continencia precoz tras la retirada del catéter; la continencia tardía, alrededor de un año después de la cirugía, se determinó mediante el número de compresas por día. Se utilizó la clasificación de Clavien-Dindo para informar las tasas de complicaciones. Las tasas de supervivencia libre de recidiva bioquímica (RB) y de supervivencia global (SG) se definieron mediante el método de Kaplan-Meier y el análisis log-rank. Se utilizaron modelos multivariantes de regresión de Cox para comprobar el efecto de los distintos factores sobre la recidiva bioquímica. Resultados Se analizaron los datos de 1.095 pacientes. La mediana de seguimiento fue de 93,4 meses. Se encontró una supervivencia global libre de RB a 10años y una SG del 73% y del 82%, respectivamente. Se observó una tasa de complicaciones de Clavien Dindo ≥3 en el 4,8% de los pacientes. La tasa de continencia precoz fue del 81,4% y la tasa de continencia tardía fue del 89,1%. El nivel de PSA preoperatorio, la suma de la puntuación de Gleason, el estadio pT, el estado de los ganglios linfáticos y el estado de los márgenes quirúrgicos fueron predictores independientes de RB (p<0,001). Entre las limitaciones del estudio están su diseño retrospectivo y unicéntrico (AU)

Introduction The surgical treatment options for prostate cancer have changed rapidly, given the expansion of robotics. However, open retropubic radical prostatectomy (ORP) will continue to be performed in areas with financial limitations or with limited access to robotics. The purpose of this study was to determine the long-term oncological outcomes, to categorize complication rates and to examine the early continence rates in patients treated with ORP. Methods We identified all patients who underwent ORP at our institution between 2000 and 2020. A standardized pad test was used to determine the early continence rates upon catheter removal, the late continence around a year after surgery was determined by the number of pads per day. The Clavien-Dindo classification was used to report the complication rates. The biochemical recurrence (BCR)-free survival and overall survival (OS) rates were defined using the Kaplan-Meier method and log-rank analysis. Multivariable Cox-regression models were used to test the effect of different factors on biochemical recurrence. Results We analyzed 1095 patients. The median follow-up was 93.4months. An overall 10-year BCR-free survival and OS of 73% and 82% respectively was found. A complication rate for Clavien Dindo ≥3 was seen in 4.8% of patients. The early continence rate was 81.4% and the late continence 89.1%. Preoperative PSA level, Gleason score sum, pT stage, lymph node status, and surgical margin status were independent predictors of BCR (P<.001). Limitations include retrospective and single centre study design. Conclusions ORP is a surgical procedure that provides excellent oncological- and early continence-rates (AU)

Identificación de parámetros pronósticos relativos a la técnica quirúrgica en pacientes tratados mediante prostatectomía radical robótica / Identifying prognostic parameters related to surgical technique in patients treated by robotic radical prostatectomy

Introducción y objetivo Los factores más estudiados en pacientes tratados mediante prostatectomía radical robótica son antígeno prostático específico (PSA) y las características patológicas de la biopsia y la pieza de prostatectomía. Los factores asociados a la técnica quirúrgica han sido poco estudiados y con resultados controvertidos. El objetivo es identificar todos los factores posibles de la cirugía y su relación con la supervivencia libre de enfermedad (SLE) y de metástasis. Pacientes y métodos Estudio prospectivo aprobado por el Comité de Ética, en pacientes intervenidos de prostatectomía radical robótica desde enero del 2009 con seguimiento mínimo de cinco años. Analizamos como posibles factores pronósticos: el cirujano, el tiempo quirúrgico, la pérdida sanguínea, el acceso fascial, las técnicas de continencia, la preservación de la fascia, las bandeletas neurovasculares, el cuello vesical, la uretra, la curva de aprendizaje y las complicaciones quirúrgicas. Realizamos comparaciones univariables y emparejadas de supervivencia mediante la estimación de Kaplan-Meier y long-rank tests. El nivel de significancia para comparaciones múltiples se estableció con ajuste False Discovery Rate (p ajustada [padj]). Resultados Cohorte de 667 pacientes con mediana de seguimiento de 69 meses. En el análisis univariante, el cirujano (padj = 0,018), la conservación de ligamentos puboprostáticos (padj = 0,02), la preservación de fascia endopélvica (padj = 0,001) y realizar suspensión parauretral (padj < 0,001) son factores de mal pronóstico para la SLE. La preservación de la fascia también afecta negativamente a la supervivencia libre de metástasis (SLM) (padj = 0,04). Las cirugías previas abdominales, la próstata, el tiempo de intervención, el sangrado, el tipo de uretra residual, el lóbulo medio, el acceso fascial, la conservación de bandeletas o cuello vesical, no tienen significancia estadística (AU)

Introduction and objective The most frequently studied factors in patients treated by robotic radical prostatectomy are PSA and pathological features of the biopsy and prostatectomy specimen. Studies on the factors associated with the surgical technique are scarce and with controversial results. The objective is to identify all possible surgical factors and their relationship with disease-free and metastasis-free survival. Patients and Method Prospective study approved by the Ethics Committee, including patients who underwent robotic radical prostatectomy since January 2009 with a minimum follow-up of 5 years. Surgeon, surgical time, blood loss, fascial access, continence techniques, preservation of the fascia, neurovascular bundles, bladder neck, urethra, learning curve and surgical complications, were analyzed as possible prognostic factors. We performed univariate and matched comparisons of survival using Kaplan-Meier estimation and long-rank tests. The significance level for multiple comparisons was established with False Discovery Rate-adjustment (adjusted p). Results Cohort of 667 patients with a median follow-up of 69 months. In univariate analysis, surgeon (adjp = 0.018), preservation of puboprostatic ligaments (adjp = 0.02), preservation of endopelvic fascia (adjp = 0.001) and performing periurethral suspension (adjp < 0.001) are poor prognostic factors for disease-free survival. Fascia preservation also negatively affects metastasis-free survival (adjp = 0.04). Previous abdominal surgeries, prostate, surgical time, blood loss, type of residual urethra, middle lobe, fascial access, fascia or bladder neck preservation, have no statistical significance. Conclusions The surgeon and specific aspects of the surgical technique are determining factors in disease-free survival. Preservation of the fascia is the only factor that negatively affects metastasis-free survival (AU)

O efeito da eletroestimulação de 65 Hz sobre a incontinência urinária, força dos músculos do assoalho pélvico e impacto na vida diária de pacientes após prostatectomia radical: experimento controlado randomizado duplo cego / The effect of 65 Hz electro stimulation on urinary incontinence, pelvic floor muscle strength and impact on daily life of patients after radical prostatectomy: double-blind randomized controlled trial

Introdução: A prostatectomia radical é um procedimento cirúrgico eficaz para a cura do câncer de próstata. Contudo, apresenta como uma das consequências a incontinência urinária (IU). Objetivo: Verificar o efeito da eletroestimulação de 65 Hz sobre a IU de pacientes com deficiência esfincteriana, consequente de uma cirurgia de prostatectomia radical. Métodos: Trata-se de um ECR duplo cego. Os pacientes passaram por uma triagem e foram alocados aleatoriamente em três grupos: Grupo exercícios dos MAP (EMAP, n = 23), grupo eletroestimulação 50 Hz mais exercícios dos MAP (EE50+EMAP,n = 19),grupo eletroestimulação 65 Hz mais exercícios dos MAP (EE65+EMAP, n = 23). A frequência semanal foi de duas vezes e a quantidade de sessões foi aquela necessária para recuperar a continência urinária, não ultrapassando de 20. Foram utilizados o risco relativo (RR) e ANOVA 3 X 2 para a análise estatística dos dados. Resultados: O risco relativo de IU do Grupo EE65+EMAP em relação ao Grupo EMAP foi igual a 0,48 (IC95% 0,31 a 0,73), enquanto que o risco relativo de IU do Grupo EE50+EMAP em relação ao Grupo EMAP foi igual a 0,89 (IC95% 0,77 a 1,04). Conclusão: A frequência de 65Hz foi mais eficaz que a de 50 Hz na recuperação da continência urinária de homens prostatectomizados.

Incidencia de la disfunción sexual eréctil asociada a la prostatectomía radical abierta y laparoscópica

Introducción: la dificultad o imposibilidad de lograr una actividad sexual satisfactoria a pesar de estar presentes las condiciones adecuadas para su desarrollo exitoso, se conoce como disfunción sexual. Si la dificultad consiste en alcanzar y mantener la erección necesaria para una penetración se produce una disfunción eréctil. Objetivo: describir la disfunción eréctil en los pacientes con cáncer de próstata sometidos a prostatectomía radical por vía abierta vs. laparoscópica, en el Hospital Universitario Comandante Faustino Pérez Hernández, de Matanzas, entre enero de 2010 y enero de 2020. Materiales y métodos: se realizó un estudio longitudinal retrospectivo en los 40 pacientes que acudieron a la Consulta Provincial de Cáncer de Próstata y les fue realizado cirugía radical, entre enero de 2010 y enero de 2020. Resultados: el 52,5 % de los pacientes tienen un promedio de edad entre 65 y 74 años. Un índice de comorbilidad de Charlson de 3 a 5 puntos predominó en un 75 % de la muestra. En la vía laparoscópica, todos los casos presentaron disfunción eréctil, siendo severa en el 50 % de ellos. El 22,5 % del total no la tuvieron, representando un 30 % de los operados por cirugía abierta. Conclusiones: la prostatectomía radical continúa siendo considerada uno de los tratamientos de elección del cáncer de próstata órgano-confinado. La causa principal de la presencia de disfunción eréctil se atribuye al procedimiento quirúrgico; la edad avanzada puede contribuir a empeorar el pronóstico y las enfermedades coadyuvantes. Son heterogéneos los resultados en la esfera sexual de la prostatectomía radical laparoscópica y la prostatectomía radical abierta, comparados con la bibliografía internacional.

Introduction: the difficulty or impossibility of achieving a successful sexual activity despite being present the adequate conditions for its successful development is known as sexual dysfunction. If the difficulty consists in reaching and maintaining the erection necessary for a penetration, erectile dysfunction occurs. Objective: to describe the erectile dysfunction in patients with prostate cancer undergoing open vs. laparoscopic radical prostatectomy, in the Comandante Faustino Perez Hernandez University Hospital, of Matanzas, between January 2010 and January 2020. Materials and methods: a longitudinal retrospective study was carried out in the 40 patients who attended Prostate Cancer Provincial Consultation and underwent radical surgery between January 2010 and January 2020. Results: 52.5% of the patients were aged between 65 and 74 on average. A Charlson comorbidity index of 3 to 5 points prevailed in 75% of the sample. In the laparoscopic pathway all the cases presented erectile dysfunction, being severe in 50% of them. 22.5% of the total did not have it, representing 30% of those operated by open surgery. Conclusions: radical prostatectomy continues to be considered one of the treatments of choice for organ-confined prostate cancer. The main cause of the presence of erectile dysfunction is attributed to the surgical procedure; advanced age can contribute to a worse prognosis and adjuvant diseases. The results in the sexual sphere of laparoscopic radical prostatectomy and open radical prostatectomy are heterogeneous compared with the international bibliography.

Identifying prognostic parameters related to surgical technique in patients treated by robotic radical prostatectomy.

INTRODUCTION AND OBJECTIVE: The most frequently studied factors in patients treated by robotic radical prostatectomy are PSA and pathological features of the biopsy and prostatectomy specimen. Studies on the factors associated with the surgical technique are scarce and with controversial results. The objective is to identify all possible surgical factors and their relationship with disease-free and metastasis-free survival. PATIENTS AND METHOD: Prospective study approved by the Ethics Committee, including patients who underwent robotic radical prostatectomy since January 2009 with a minimum follow-up of 5 years. Surgeon, surgical time, blood loss, fascial access, continence techniques, preservation of the fascia, neurovascular bundles, bladder neck, urethra, learning curve and surgical complications, were analyzed as possible prognostic factors. We performed univariate and matched comparisons of survival using Kaplan-Meier estimation and long-rank tests. The significance level for multiple comparisons was established with False Discovery Rate-adjustment (adjusted p). RESULTS: Cohort of 667 patients with a median follow-up of 69 months. In univariate analysis, surgeon (adjp=0.018), preservation of puboprostatic ligaments (adjp=0.02), preservation of endopelvic fascia (adjp=0.001) and performing periurethral suspension (adjp<0.001) are poor prognostic factors for disease-free survival. Fascia preservation also negatively affects metastasis-free survival (adjp=0.04). Previous abdominal surgeries, prostate, surgical time, blood loss, type of residual urethra, middle lobe, fascial access, fascia or bladder neck preservation, have no statistical significance. CONCLUSIONS: The surgeon and specific aspects of the surgical technique are determining factors in disease-free survival. Preservation of the fascia is the only factor that negatively affects metastasis-free survival.

Open retropubic radical prostatectomy: Still a well-established surgical technique for prostate cancer management.

INTRODUCTION: The surgical treatment options for prostate cancer have changed rapidly, given the expansion of robotics. However, open retropubic radical prostatectomy (ORP) will continue to be performed in areas with financial limitations or with limited access to robotics. The purpose of this study was to determine the long-term oncological outcomes, to categorize complication rates and to examine the early continence rates in patients treated with ORP. METHODS: We identified all patients who underwent ORP at our institution between 2000 and 2020. A standardized pad test was used to determine the early continence rates upon catheter removal, the late continence around a year after surgery was determined by the number of pads per day. The Clavien-Dindo classification was used to report the complication rates. The biochemical recurrence (BCR)-free survival and overall survival (OS) rates were defined using the Kaplan-Meier method and log-rank analysis. Multivariable Cox-regression models were used to test the effect of different factors on biochemical recurrence. RESULTS: We analyzed 1095 patients. The median follow-up was 93.4 months. An overall 10-year BCR-free survival and OS of 73% and 82% respectively was found. A complication rate for Clavien Dindo≥3 was seen in 4.8% of patients. The early continence rate was 81.4% and the late continence 89,1%. Preoperative PSA level, Gleason score sum, pT stage, lymph node status, and surgical margin status were independent predictors of BCR (p<0.001, 95% CI). Limitations include retrospective and single center study design. CONCLUSIONS: ORP is a surgical procedure that provides excellent oncological- and early continence-rates.

Cytoreductive surgery in patients with oligometastatic prostate cancer. Systematic review of the scientific literature.

INTRODUCTION: Interest in oligometastatic prostate cancer has spiked due to the emergence of new evidence regarding more specific and accurate imaging, and the wider use of minimally invasive techniques. Nevertheless, the optimal management of this pathology is yet to be determined. OBJECTIVE: Assess the efficacy and safety of cytoreductive surgery in patients suffering from oligometastatic prostate cancer. EVIDENCE GATHERING: Systematic review of the scientific literature (01/01/2010-31/12/2021) within the MedLine, Embase, Cochrane Library, Cinahl, Scopus, Spanish Healthcare Technology Assessment Agencies (AETS, Agencias de Evaluación de Tecnologías Sanitarias) and ClinicalTrials.gov databases. The keywords used were prostatectomy, prostatic neoplasm, radical prostatectomy; the free search terms were prostatectomy and oligometastatic prostate. The inclusion criteria comprised studies on patients with oligometastatic prostate cancer who had been operated on using radical cytoreductive prostatectomy. EVIDENCE SYNTHESIS: The systematic review included 4 observational studies, 2 clinical trials, and 2 case series, of moderate quality. The results observed suggest that oligometastatic prostate cancer patients who had undergone cytoreductive prostate surgery obtained a benefit in terms of efficacy. Conversely, the majority of these studies showed a reduction in the number of localized complications, when compared to the best systemic treatments. CONCLUSIONS: Cytoreductive surgery in this group of patients is a safe procedure that reduces the incidence of localized complications and that presents promising results with regard to survival rates. To date, the lack of prospective trials limits the use of this therapeutic option to experimental environments.

Tumor fibroso solitario de próstata: informe de caso y revisión de la literatura / Solitary fibrous tumor of the prostate: case report and literature review

El tumor fibroso solitario (TFS) es una neoplasia mesenquimatosa de tipo fibroblástico que, a pesar de ser localizado principalmente en pleura, se ha observado en otros órganos como la próstata. Por su parte, el tumor fibroso solitario de la próstata es una neoplasia de baja incidencia, crecimiento lento y potencial maligno incierto, que generalmente se compone de células fusiformes de apariencia citológicamente benignas, dispuestas en una arquitectura desorganizada, mezcladas con colágeno y pequeños vasos sanguíneos. Establecer su diagnóstico se ha vuelto más reproducible desde la identificación de la fusión de los genes NAB2-STAT6 por biología molecular, que lleva a la sobreexpresión de STAT6 por inmunohistoquímica, el cual es un marcador muy sensible y específico para TFS. Presentamos el caso clínico de un paciente que debutó con síntomas de compresión vesical, en quien se identificó una masa con epicentro en la próstata que infiltraba la vejiga y llegaba a la pared rectal, y que luego de estudios de patología, inmunohistoquímica y pruebas moleculares se clasificó como un TFS de la próstata, finalmente tratado con cistoprostatectomía radical más derivación urinaria

Solitary fibrous tumor (SFT) is a mesenchymal neoplasm of fibroblastic type, which despite being located mainly in the pleura, has been observed in other organs such as the prostate. On the other hand, solitary fibrous tumor of the prostate is a rare neoplasm, slow growing, and of uncertain malignant potential, which is generally composed of spindle cells of cytologically benign appearance, arranged in a disorganized architecture, mixed with collagen and small blood vessels. Establishing its diagnosis has become more reproducible since the identification of the NAB2-STAT6 gene fusion by molecular biology, leading to the overexpression of STAT6 by immunohistochemistry, a very sensitive and specific marker for SFT. We present a clinical report of a patient who consulted with symptoms of bladder compression, in whom a mass was identified with the epicenter in the prostate infiltrating into the bladder and reaching the rectal wall. Following histopathology study, immunohistochemistry and molecular tests it was classified as a SFT of the prostate, finally treated with radical cystoprostatectomy plus urinary shunt

Migración de catéter ureteral doble-J a vena cava inferior, una complicación inusual / Migration of double-J ureteral catheter into the inferior vena cava, an unusual complication

La colocación de catéteres ureterales doble-J es uno de los procedimientos más realizados en Urología, con bajas tasas de complicaciones graves. No obstante, pueden ocurrir y requieren de una identificación y tratamiento precoz. Presentamos el caso de un varón de 73 años intervenido de una prostatectomía radical, al que se le coloca un catéter doble-J por sospecha de lesión ureteral durante la intervención, con inestabilidad hemodinámica en el postoperatorio inmediato secundaria a la migración del catéter a la vena cava inferior

Double-J ureteral catheter placement is one of the most commonly performed procedures in Urology, with low rates of severe complications. Nevertheless, they can occur and require early identification and treatment. We present the case of a 73-year-old man who underwent radical prostatectomy and placement of a double-J catheter due to suspected ureteral injury during the surgery, with hemodynamic instability in the immediate postoperative period secondary to intracaval migration of the catheter.

Comparative analysis between open transvesical and laparoscopic adenomectomy in the treatment of benigne prostatic hyperplasia in a tertiary hospital in Curitiba-PR: a retrospective study / Análise comparativa entre adenomectomia transvesical aberta e videolaparoscópica no tratamento da hiperplasia prostática benigna em hospital terciário de Curitiba - PR: estudo retrospectivo

ABSTRACT Objective: the aim of this study was to compare the results of open and videolaparoscopic transvesical prostatectomy techniques in the treatment of benign prostatic hyperplasia (BPH) in a tertiary hospital. Methods: we reviewed medical records of patients who underwent transvesical adenectomy due to BPH between March 2019 and March 2021 at the urology service of Hospital de Clínicas do Paraná (HCPR), 42 patients were included in the open transvesical prostatectomy group and 22 in the videolaparoscopic group. Then, a comparison was made between the techniques in terms of surgical time, bleeding, length of stay, need for intensive care, among others, in addition to postoperative outcome. Results: the mean surgical time was shorter in the open technique compared to the laparoscopic technique (141 min vs 274 min). The videolaparoscopic group had a shorter mean hospital stay (3.5 days vs 6.36 days). There was no statistical significance in the comparison regarding the need for an intensive care unit, as well as in the assessment of postoperative bleeding. Conclusion: comparatively, the techniques demonstrated a similar outcome, with a low rate of complications and satisfactory results for the treatment of BPH. The laparoscopic technique is a surgery with a shorter hospital stay, but at the expense of a longer surgical time.

RESUMO Objetivo: o objetivo deste estudo foi comparar o resultado das técnicas de prostatectomia transvesical aberta e videolaparoscópica no tratamento de hiperplasia prostática benigna (HPB) em um hospital terciário. Métodos: foram revisados prontuários de pacientes submetidos a adenectomia transvesical devido a HPB entre março de 2019 a março de 2021 no serviço de urologia do Hospital de Clínicas do Paraná (HCPR), sendo incluídos 42 pacientes no grupo prostatectomia transvesical aberta e 22 no grupo videolaparoscópico. Em seguida foi feita a comparação entre as técnicas nos quesitos tempo cirúrgico, sangramento, tempo de internamento, necessidade de terapia intensiva, entre outras, além de desfecho pós-operatório. Resultados: o tempo cirúrgico médio foi menor na técnica aberta em comparação com a técnica videolaparoscópica (141 min vs 274 min). O grupo videolaparoscópico apresentou um tempo médio de internamento menor (3,5 dias vs 6,36 dias). Não houve significância estatística na comparação quanto a necessidade de unidade de terapia intensiva, assim como na avaliação do sangramento pós-operatório. Conclusão: comparativamente, as técnicas demonstraram um desfecho semelhante, com baixa taxa de complicações e resultados satisfatórios para o tratamento da HPB. Sendo a técnica videolaparoscópica uma cirurgia com menor tempo de internamento, porém às custas de um maior tempo cirúrgico. .

Robotic-assisted laparoscopic radical prostatectomy: Initial outcomes of 500 cases.

INTRODUCTION: We aimed to present our experience of robot-assisted laparoscopic radical prostatectomy (RARP). MATERIAL AND METHODS: The study was a retrospective review of 500 patients who underwent RARP between March 2015 and July 2021 in our clinic. A transperitoneal approach was used in all patients. All patients had clinically organ-confined prostate cancer (≤ cT2c). RESULTS: The mean age of the patients was 64.6 ± 5.7 years. The median PSA was 11.4 ng/dL (range 0.3-92.7). The mean operative time was 183.5 min. Positive surgical margin rate was 19.4%. During a mean follow-up of 23.5 months, 96 patients (19.2%) received adjuvant radiotherapy due to the biochemical recurrence and 28 patients (16%) with lymph node positivity received early adjuvant hormone therapy. Considering the continence rates, 69% of the patients were total continence in the 3rd month, while this rate increased to 83 in the 6th month and 91% in the 12th month. CONCLUSION: RARP is a safe and feasible method for experienced centers with patient comfort, surgeon comfort, and successful oncological and functional results.

En todos los pacientes se utilizó un abordaje transperitoneal. Todos los pacientes tenían cáncer de próstata limitado al órgano clínicamente (≤ cT2c). RESULTADOS: La edad media de los pacientes fue de 64.6 ± 5.7 años. La mediana de PSA fue de 11.4 ng/dL (rango 0.3-92.7). El tiempo operatorio medio fue de 183.5 min. La tasa de márgenes quirúrgicos positivos fue del 19,4%. Durante un seguimiento medio de 23.5 meses, 96 pacientes (19.2%) recibieron radioterapia adyuvante debido a la recurrencia bioquímica y 28 pacientes (16%) con ganglios linfáticos positivos recibieron terapia hormonal adyuvante temprana. Considerando las tasas de continencia, el 69% de los pacientes tenían continencia total en el 3er mes, mientras que esa tasa aumentó a 83 en el 6° mes y 91% en el 12° mes. CONCLUSIÓN: RARP es un método seguro y factible para centros experimentados con comodidad para el paciente, comodidad para el cirujano y resultados oncológicos y funcionales exitosos.

Estudio poblacional de casuística y morbimortalidad de la prostatectomía radical en España / Population based study of morbidity and mortality rates associated to radical prostatectomy cases in Spain

Introducción: No existe ningún estudio poblacional que contabilice en número de prostatectomías radicales (PR) realizadas España, ni la morbimortalidad de dicha intervención.Nuestro objetivo es estudiar la morbimortalidad de la PR en España desde el 2011 al 2015 y evaluar la variabilidad geográfica. Material y métodos: Diseñamos un estudio observacional retrospectivo de todos los pacientes intervenidos de PR en España durante cinco años consecutivos (2011-2015) a partir de los datos registrados en el Conjunto Mínimo Básico de Datos (CMBD).Hemos estudiado la distribución del número de casos y la variabilidad intercomunitaria en términos de morbilidad y de estancia hospitalaria, así como el impacto del volumen quirúrgico medio anual por cada centro en dichas variables. Resultados: Entre los años 2011-2015 se han realizado un total de 37.725 PR en 221 hospitales españoles públicos del sistema nacional de salud. La edad media de la serie fue 63,9 ± 3,23 años. El 50% de las PR se han realizado por vía abierta, y un 43,4% se han intervenido en hospitales de < 500 camas. Encontramos una gran variabilidad en la distribución de los casos intervenidos en las distintas Comunidades Autónomas (CCAA Las comunidades que realizan un mayor número de prostatectomías son Andalucía, Cataluña, Galicia y Madrid. La tasa de complicaciones a nivel nacional es de 8,6%, siendo las más frecuentes la hemorragia y necesidad de transfusión (5,3 y 4%, respectivamente). Encontramos importantes diferencias en las tasas de hemorragia y en la estancia hospitalaria entre las distintas CCAA, que se mantienen tras ajustar por las características del paciente y del tipo de hospital. Al estudiar el volumen quirúrgico anual de cada hospital vemos que el impacto en la tasa de hemorragia o transfusión es lineal sin embargo en la estancia a partir de 60 PR/año la estancia se mantiene estable en torno a cinco días. (AU)

Introduction: There is no population-based study that accounts for the number of radical prostatectomies (RP) carried out in Spain, nor regarding the morbidity and mortality of this intervention.Our objective is to study the morbidity and mortality of RP in Spain from 2011 to 2015 and to evaluate the geographic variation. Material and methods: We designed a retrospective observational study of all patients submitted to RP in Spain during five consecutive years (2011-2015). The data was extracted from the «Conjunto Mínimo Básico de Datos» (CMBD).We have evaluated geographic variations in terms of morbidity and hospital stay, and the impact of the mean annual surgical volume for each center on these variables. Results: Between 2011-2015, a total of 37,725 RPs were performed in 221 Spanish public hospitals. The mean age of the series was 63.9 ± 3.23 years. Of all RPs, 50% were performed through an open approach, and 43.4% have been operated on in hospitals with < 500 beds. We observed an important variability in the distribution of the cases operated on in the different regions. The regions that perform more RPs are Andalusia, Catalonia, Galicia, and Madrid. Our study shows a complication rate of 8.6%, with hemorrhage and the need for transfusion being the most frequent (5.3 and 4%, respectively). There are significant differences in bleeding rates and hospital stay among regions, which are maintained after adjusting for patient characteristics and type of hospital. When studying the annual surgical volume of each hospital, we find that the impact on the rate of hemorrhage or transfusion is linear; however, hospital stay remains stable at around 5 days from 60 RPs/year (AU)
