ABSTRACT

OBJECTIVE: To determine the prognostic impact that tumor size has in patients with pathological renal cancer stage pT3a. METHODS: Retrospective, descriptive study evaluating 261 patients diagnosed with renal cancer pathological stage pT1-3aN0M0 between 1995 and 2013. Clinical and pathological characteristics were evaluated in each group. A ROC curve was used to determine the optimum cutting point of tumor size in relation to the death by cancer. Metastasis-free survival and cancer specific survival were evaluated by the Kaplan Meier method and the differences between the groups were evaluated by the Log Rank test. Multivariate Cox regression analysis was used to evaluate the relationship of tumor size and survival of these patients. RESULTS: 261 patients were studied, 166 of which (63.6%) were Stage pT1a-b, 49 (18.8%) pT2 and 46 (17.6%) pT3a. Patients with pT3a tumors had higher proportion of symptomatic tumors (56.5% vs 33.6% p 0.003), tumor size (7.1 cm vs 5.5 cm; 0.0007), Fuhrman grade 3-4 (52.2% vs 19.1% p 0.0001), coagulative necrosis (62.8% vs 28.8% p 0.0001), distance metastasis (39.1% vs 14.9%; p 0.0001) and death by cancer (23.9% vs 8.9%; p 0.003) when compared with localized tumors (pT1-2). The ROC curve demonstrated that a cut-off point of 7cm is the ideal tumor size to determine renal cancer mortality. Metastasis-free survival at 5 year was 90% for tumors pT1a-b, 71% for pT2, 83% for pT3a <7cm and 48% for pT3a >7cm, with significant statistical differences (Log-rank test <0.001). In the multivariate analysis, only pT3a >7cm stage was an independent predictor of death by renal cancer. CONCLUSIONS: Although perirenal fat invasion and renal vein invasion (pT3a stage) are accepted as prognostic factors, to differentiate this category by tumor size could improve its predictive quality. The tumor diameter (7cm) should be applied to pT3a tumors in order to improve the accuracy of TNM system.

ABSTRACT

OBJETIVO: Determinar el impacto pronóstico que tiene el tamaño tumoral en pacientes con cáncer renal estadio patológico pT3a. MÉTODOS: Estudio retrospectivo, descriptivo donde se evaluaron 261 pacientes con diagnóstico de cáncer renal estadío patológico pT1-3aN0M0 entre 1995 y 2013. En cada grupo se evaluaron características clínicas y patológicas. Para determinar el punto de corte óptimo del tamaño tumoral en relación a la muerte por cáncer se utilizó una curva ROC. La supervivencia libre de metástasis y la supervivencia cáncer específico, fueron evaluados por el método de Kaplan Meier y las diferencias entre los grupos fueron evaluadas por el Log Rank test. El análisis multivariado de regresión de Cox fue utilizado para evaluar la relación del tamaño tumoral en la supervivencia de estos pacientes. RESULTADOS: Se estudiaron 261 pacientes de los cuales 166 (63,6%) son estadío pT1a-b, 49 (18,8%) pT2 y 46 (17,6%) pT3a. Los pacientes con tumores pT3a presentaron mayor proporción de tumores sintomáticos (56,5% vs 33,6%; p 0,003), diámetro tumoral (7,1 cm vs 5,5 cm; p 0,0007), grado de Fuhrman 3-4 (52,2% vs 19,1%; p 0,0001), necrosis coagulativa (62,8% vs 28,8%; p 0,0001), metástasis a distancia (39,1% vs 14,9%; p 0,0001) y muerte por cáncer (23,9% vs 8,9%; p 0,003) al ser comparados con tumores localizados (pT1-2). Por medio de una curva ROC evidenciamos que un punto de corte de 7cm es el tamaño tumoral ideal para determinar mortalidad por cá7ncer renal. La supervivencia libre de metástasis a los 5 años fue 90% para tumores pT1a-b, 71% para pT2, 83% para pT3a <7cm y 48% para pT3a > 7cm, con diferencias estadísticamente significativas (Log rank test <0,001). En el análisis multivariado, evidenciamos al estadío pT3a >7cm como el único factor predictivo independiente de muerte por cáncer renal. CONCLUSIONES: Aunque la invasión de la grasa perirrenal y la invasión de la vena renal (estadío pT3a) son factores pronósticos aceptados, discriminar esta categoría según el tamaño tumoral podría mejorar su calidad predictiva. Nuestros datos demuestran que el diámetro tumoral (7cm) debería ser aplicado a tumores pT3a con el fin de mejorar la exactitud del sistema TNM

ABSTRACT

OBJETIVOS: Realizar una validación externa del Score CAPRA-S para determinar si predice recurrencia bioquímica, metástasis y muerte por CAP tras PR en pacientes argentinos. MÉTODOS: Se estudiaron 216 pacientes. La probabilidad del Score para predecir recurrencia bioquímica después de PR fue analizada por método proporcional de Cox. La supervivencia libre de recurrencia bioquímica, metástasis y cáncer específico fue determinada por el método de Kaplan. La exactitud del Score de CAPRA-S para predecir recurrencia bioquímica, metástasis y muerte por CAP fue realizada de acuerdo al índice de concordancia de Harrell's. RESULTADOS: La media de seguimiento fue 74 meses. El índice de recurrencia bioquímica aumenta proporcionalmente al aumentar el Score CAPRA-S. Cuando estratificamos los pacientes en riesgo bajo, intermedio y alto, la tasa libre de recurrencia bioquímica fue 85%, 54% y 4% respectivamente. El índice de concordancia (C-Index) para progresión bioquímica, metástasis y muerte por CAP fue 0,85, 090 y 0,90 respectivamente. CONCLUSIONES: El Score CAPRA-S es una herramienta fácilmente aplicable y de gran exactitud predictiva para determinar la probabilidad de recurrencia bioquímica, metástasis y muerte por CAP en nuestra población. El índice de concordancia (C-Index) en estas variables es superior a 0,85


OBJECTIVES: To perform an external validation of CAPRA-S Score to determine prediction of biochemical recurrence, metastasis and death by PCa after RP in Argentinian population. METHODS: 216 patients were studied. The probability of the score to predict biochemical recurrence after RP was analyzed by the Cox proportional method. Biochemical recurrence, metastasis and cancer specific free survivals were determined by Kaplan method. The accuracy of CAPRA-S score to predict biochemical recurrence, metastasis and death by PCa was made in accordance with Harrells concordance index. RESULTS: Median follow up was 74 months. Biochemical recurrence index increased proportionally with the increment of CAPRA-S score. In the stratification of patients in low, intermediate or high risk, biochemical recurrence free rates were 85%, 54% and 4% respectively. Concordance index (C-Index) for biochemical progression, metastasis and death by PCa were 0.85, 0.90 and 0.90 respectively. CONCLUSIONS: CAPRA-S score is an easily applicable tool and has high predictive accuracy to determine biochemical recurrence, metastasis and death by PCa probabilities in our population. Concordance Index in these variables was higher than 0.85

ABSTRACT

OBJECTIVES: To assess the association between empty bladder stress test and objective and subjective measures of stress urinary incontinence (SUI) severity. METHODS: Prospective, analytic and descriptive study of females with diagnosis of stress urinary incontinence referred for urodynamics study. Every patient underwent medical history (including number of daily pads) and physical examination, ISIQ-SF and short IIQ-7 questionnaires, and full urodynamic study, including the measurment of the abdominal leak pressure point (ALPP). Positive empty stress test was defined as stress urine leak on physical exam after uroflowmetry evacuation and in absence of significant post-void residual. To evaluate the relationship between empty bladder stress test and each one of the stress urinary incontinence severity measures, Stundent's t test was performed, considering a 〈0.05 value statistically significant. RESULTS: 107 patients were studied in the final analysis; of them 49 had empty bladder stress test (+) and 58 (-). Patients with positive test wet a greater number of protectors per day (3.9 vs 2.8; p 0.013), higher ICIQSF score (15.04 vs 12.22; p 0.0007), higher IIQ-7 score (52.2 vs 37.5; p 0.0049) and lower urodynamics ALPP (73 cm H2O vs 91 cm H2O; p 0.0002). CONCLUSIONS: Patients with SUI and positive empty bladder stress test had a strong association with the objective and subjective perception of urine incontinence severity with a negative impact in patients quality of life.

ABSTRACT

OBJETIVOS: Evaluar la asociación entre la prueba de vejiga vacía en posición supina y mediciones objetivas y subjetivas de severidad de incontinencia de orina de esfuerzo (IOE). MÉTODOS: Se realiza un estudio prospectivo, analítico y descriptivo de mujeres derivadas para estudio urodinámico por incontinencia de orina de esfuerzo. A todas las pacientes se les realizó interrogatorio (incluyendo número de protectores diarios) y examen físico, cuestionarios ISIQ-SF, IIQ-7 corto y estudio urodinámico completo (incluyendo medición de punto de presión de pérdida abdominal (VLPP)). La prueba de vejiga vacía en posición supina positiva fue definida como la pérdida de orina de esfuerzo al examen físico posterior a la evacuación vesical en la uroflujometría y en ausencia de residuo postmiccional significativo. Para evaluar la relación entre el resultado del test de vejiga vacía y cada una de las mediciones de severidad de incontinencia de orina de esfuerzo se realizó el test de Student, considerando un valor <0,05 como estadísticamente significativo. RESULTADOS: Se estudiaron 107 pacientes en el análisis final, de los cuales 49 presentaban test de vejiga vacía (+) y 58 test de vejiga vacía (-). Las pacientes con test (+) refirieron utilizar un mayor número de protectores por día (3,9 vs 2,8; p 0,013), mayor puntuación en el cuestionario ICIQ-SF (15,04 vs 12,22; p 0,0007), mayor puntaje en el cuestionario de impacto de incontinencia IIQ-7 (52,2 vs 37,5; p 0,0049) y menor VLPP en el estudio urodinámico (73 cm H2O vs 91 cm H2O; p 0,0002). CONCLUSIONES: Las pacientes con IOE que presentan test de vejiga vacía (+) tienen una fuerte asociación con la percepción objetiva y subjetiva de la severidad de la incontinencia de orina con un impacto negativo en la calidad de vida de la paciente

ABSTRACT

El APE ha derivado en el diagnóstico de CaP en etapas más tempranas de la enfermedad. Por otra parte, existen evidencias de que muchos pacientes son sobretratados. La vigilancia activa tiene como premisa reducir el sobre tratamiento y la morbilidad relacionada con el tratamiento primario. El objetivo de este estudio fue evaluar las características patológicas desfavorables en pacientes sometidos a PR que fueron estratificados pre-operatoriamente de bajo riesgo según 10 modalidades para definir pacientes posibles de seguimiento activo. Realizamos un estudio retrospectivo y analítico de 230 pacientes con diagnóstico de CAP y tratados con PR, realizadas entre 1999 y 2011 en el Centro Urológico Profesor Bengió. Se evaluaron las características clínicas en 10 protocolos de seguimiento activo. Las variables anatomopatológicas evaluadas en la pieza de PR fueron el estadio patológico, SG de la pieza operatoria, la extensión extraprostática (EEP), invasión de vesículas seminales y compromiso de ganglios linfíticos regionales. El informe histopatológico fue realizado por un único uropatólogo (VB).En cada uno de los protocolos se evalúa el índice de recurrencia bioquímica. La población del estudio fue 198 pacientes. La media de edad fue 63 años. La media de APE 12,4/ml. Predominaron los estadíos clínicos T1c (48 por ciento) y T2 (48 por ciento). El índice de concordancia entre el SG de la biopsia y la PR en la serie se observó en 128 pacientes (64,6 por ciento). La extensión extraprostática, invasión de vesículas seminales e invasión ganglionar fue encontrada en 44 (22,2 por ciento), 38 (19,2 por ciento) y 3 (1,5 por ciento) pacientes respectivamente. La presencia de elementos patológicos desfavorables en pacientes candidatos a seguimiento activo oscila entre 12 por ciento y el 32 porciento. En nuestra serie de pacientes tratados con prostatectomía radical, los esquemas de vigilancia activa más estrictos, basados en APE <10ng/ml,...


The PSA has resulted in the diagnosis of prostate cancer in earlier stages of the disease. Moreover, there is evidence that many patients are over-treated. Active surveillance tries to prevent overtreatment and reduce the morbidity associated with primary treatment. The aim of this study was to evaluate the adverse pathologic features in patients who underwent RP and were stratified preoperatively as potential candidate for active surveillance through 10 different protocols. A retrospective study of 230 patients diagnosed with CAP treated with PR, conducted between 1999 and 2011 in the Urological Center Professor Bengio. Clinical characteristics were evaluated in 10 active surveillance protocols. Pathologic variables evaluated in RP specimens were pathological stage, surgical specimen SG, extraprostatic extension (EEP), seminal vesicle invasion and regional lymph nodes. The histopathological report was done by a single uropathologist (VB). In each of the protocols biochemical recurrence rate was evaluated. The study population was 198 patients. The average age was 63. The mean PSA 12.4 / ml. Predominant clinical stages T1c (48 percent) and T2 (48 percent). The concordance rate between the SG biopsy and RP in the series was observed in 128 patients (64.6 percent). Extraprostatic extension, seminal vesicle invasion and lymph node involvement was found in 44 (22.2 percent), 38 (19.2 percent) and 3 (1.5 percent) patients, respectively. The presence of unfavorable pathological elements in candidates for active surveillance patients ranges from 12 percent to 32 percent. In our series of patients treated with radical prostatectomy, stricter schemes of active surveillance based on PSA <10ng/ml, clinical stage T1c-T2a, biopsy Gleason score ¡Ü 6 and minimally invasive biopsy (<2 cylinders and <50 percent involvement) show better agreement with favorable histopathology findings in radical prostatectomy and correspond with greater biochemical recurrence-free survival...

ABSTRACT

Los criterios de Epstein (densidad del antígeno prostático específico <0,15, score de Gleason en la biopsia <6, menos de 3 cilindros comprometidos, menos del 50 por ciento de afectación por cilindro) representan el método más utilizado para predecir cáncer de próstata clínicamente insignificante y, por lo tanto, susceptible de conductas conservadoras. Objetivos: Evaluar la existencia de elementos pronósticos desfavorables en el estudio de la pieza operatoria de pacientes con criterios preoperatorios de cáncer insignificante. Materiales y métodos: Entre 1999 y 2009, 220 pacientes fueron sometidos a prostatectomía radical (PR) en nuestra institución. Se incluyeron 183 pacientes que reunían los criterios de inclusión y exclusión. De los mismos 29 (15,3 por ciento) cumplían con todos los criterios de cáncer clínicamente insignificante. Se consideraron elementos de pronóstico patológicamente desfavorables, el score de Gleason 7 o más y/o enfermedad extra prostática en el estudio del espécimen quirúrgico. Resultados: La presencia de suma de Gleason 7 o mayor fue evidenciado en 6 pacientes (21,4 por ciento) con cáncer clínicamente insignificante. Tres de estos presentaron enfermedad extraprostática. Cuatro experimentaron recurrencia bioquímica con una media a la recurrencia de 24 meses. Comentarios: La correlación entre los criterios clínicos de Epstein para definir CaP insignificante con los resultados histopatológicos de la pieza operatoria muestra diferencias significativas en algunos casos. Las mismas residen básicamente en la diferencia de la evaluación del" score de Gleason de la biopsia y de la pieza operatoria, y entre la estadificación clínica y patológica...


Epstein criteria (prostate specific antigen density <0.15, Gleason score on biopsy <6, less than 3 cylinders engaged, less than 50 percent of affected per cylinder) are the most wide/y used method for predicting prostate cancer clinically insignificant and, therefore, susceptible to conservative behavior. Objectives: Evaluate the existence of unfavorable prognostic elements in the study of the surgical specimen of patients with preoperative criteria of insignificant cancer. Materials and methods: Between 1999 and 2009, 220 patients where treat by means of radical prostatectomy (RP) at our institution. We included 183 patients who met the inclusion and exclusion criteria. 29 (15.3 percent) met all criteria for clinically insignificant cancer. We considered as elements of pathologically unfavorable prognosis the Gleason score of 7 or more, and confined disease in the study of the surgical specimen. Results: The presence of Gleason sum 7 or greater was demonstrated in 6 patients (21.4 percent) wit clinically insignificant cancer. Three of these had organ confined disease. 4 experienced biochemical recurrence with a mean recurrence of 24 months. Comments: The correlation between clinical criteria to define insignificant prostate cancer with histopathological findings of the resected specimen shows significant difference in some cases. Basically the same lie in the difference in the assessment of Gleason score of biopsy and surgical specimen, and between clinical and pathological staging. This suggests that Epstein definitions based on clinical parameters must be assumed as elements of guidance only and not as absolute certainty criteria for qualification of insignificant cancer. Conclusions: Epstein criteria for clinically insignificant prostate cancer underestimate the malignant potential in the 21.4 percent of patients ¡n our series...

ABSTRACT

El score de Gleason (SG) es un importante predictor de resultados en cáncer de próstata. El SG 7 es un grupo heterogéneo que presenta en las diversas series un riesgo de muerte cáncer específico del 29 por ciento-41 por ciento. La diferenciación de los casos en que el patrón dominante sea 3(3+4) y los casos en donde el patrón dominante sea 4 (4+3) podría representar un factor pronóstico significativo. Objetivos: Evaluar las diferencias clínicas, patológicas y evolutivas de pacientes con prostatectomía radical con score de Gleason 3+4 y 4+3.Materiales y métodos: Se consideraron 73 pacientes con score de Gleason 7 en el espécimen de prostatectomía radical entre 1999 y 2009. Se evaluaron variables clínicas (antígeno prostático específico (APE), estadio clínico y score de Gleason de la biopsia) y patológicas (estadio patológico, Gleason, márgenes quirúrgicos, invasión de vesículas seminales, compromiso ganglionar). Como punto de corte se utilizó la recurrencia bioquímica y la mortalidad cáncer específica. Se consideró fallo bioquímico a la elevación de APE por encima de 0,2 ng/ml con dos ascensos sucesivos. Resultados: En los 73 pacientes, 48 (65,8 por ciento) y 25 (34,2 por ciento) tuvieron score de Gleason 3+4 y 4+3 respectivamente en la pieza operatoria. Esto contrasta con el Gleason de la biopsia previa que sub graduó 54 por ciento para el grupo 3+4 y 32por ciento para el grupo 4+3. Los valores de APE correlacionaron el score de Gleason, siendo el promedio del marcador de 14,4 ng/ml para el grupo 3+4 y 17,7 ng/ml para el grupo 4+3. El grupo de patrón predominante 4 se asoció a mayor estadio patológico, no notándose diferencias significativas en lo referente a márgenes quirúrgicos positivos. La sobre vida libre de recurrencia bioquímica a los 5 años fue de 54,2por ciento en el grupo con patrón predominante 3, con una media al fallo de APE de 14 meses...


The Gleason score (GS) is an important predictor of outcome in prostate cancer. The SG 7 is a heterogeneous group in several series presents a specific cancer death risk of 29 percent-41 percent. The differentiation of cases in which the dominant pattern is 3 (3 +4) and cases where the dominant pattern is 4 (4 +3) could be a significant prognostic factor Objectives: Evaluate the different clinical, pathological and outcome of patients who underwent to radical prostatectomy whit a Gleason score 3+4 and 4+3.Materials and methods: We considered 73 patients with Gleason Score 7 in the specimen of radical prostatectomy between 1999 and 2009. Clinical variables were evaluated (prostate specific antigen (PSA), clinical stage and Gleason score of the biopsy) and pathological (pathological stage, Gleason score, surgical margins, seminal vesicle invasion, lymph node invasion). We used biochemical recurrence and cancer-specific mortality as our end point. Biochemical failure was a PSA rise above0.2 ng/ml with two successive determinations. Results: In the 73 patients, 48 (65.8 percent) and 25 (34.2 percent) had Gleason score 3 +4 and 4 +3, respectively, in the specimen. This contrasts with the previous biopsy Gleason which undergraduate 54 percent for group3+4 and 32 percent for the 4 +3. PSA values correlated the Gleason score, where the average score of 14.4 ng/ml for group 3 +4 and 17.7 ng/ml for group 4 +3. The predominant pattern group 4 was associated with higher pathological stage, no significant differences being noted in terms of positive surgical margins. The biochemical recurrence-free survival at 5 years was 54.2 percent in the group with the predominant pattern 3, with a mean to PSA failure of 14 months. In group 4, the predominant pattern of biochemical recurrence-free survival at 5 years was 16 percent, with a mean to recurrence of 5.8 percent months...
