External validation of the Gleason grade group system in Argentinian patients that underwent surgery for prostate cancer.

INTRODUCTION: The aim of this article was to evaluate the effectiveness of the Gleason grade groups (GGG) system on a group of Argentinian patients with prostate cancer (PC) who underwent radical prostatectomy (RP). MATERIAL AND METHODS: We retrospectively studied 262 patients who underwent RP between 1996 and 2014. To determine the performance and validity of the GGG system, a Kaplan-Meier analysis and multivariate analysis with Cox proportional method were performed to evaluate biochemical recurrence, distance metastases and specific cancer mortality. The area under the curve (AUC) was calculated to compare new groups of degrees of the GGG system with the classical scheme of stratification into 3 groups. RESULTS: The median follow-up was 84 months. As the groups ascend, there is less confined organ disease (p <0.001) and greater extraprostatic extension (p <0.001), greater invasion of seminal vesicles (p <0.001) and greater lymph node involvement (p <0.001). The biochemical recurrence-free survival at 5 years was 68%, 55%, 22%, 9%, 0% of the 1-5 groups, respectively. Ten-years cancer-specific survival was 96%, 95%, 78%, 64%, 25% for group 1-5, respectively. In the multivariate analysis, the GGG system is presented as the only independent predictor of biochemical recurrence and specific cancer mortality. The AUC indicates that the GGG system has a higher prognostic discrimination compared to the classic 3-group system (6, 7, ≥8). CONCLUSIONS: The International Society of Urological Pathology (ISUP) GGG system is an independent predictor of biochemical recurrence and mortality from prostate cancer in patients treated with RP. The classification into 5 groups shows greater discrimination in the prognosis than the traditional Gleason classification.

Clinical score predictive of abdominal leak point pressure (ALPP) <60 cm H2O in the urodynamics study of women with stress urinary incontinence.

OBJECTIVE: The aim of this study was to perform a score predictive of ALPP <60 cm H2O from clinical factors in women with stress urinary incontinence (SUI). STUDY DESIGN: We performed a descriptive and observational study of women referred for a urodynamic study for stress urinary incontinence. Patients were divided into three groups: ALPP: >90 cm H2O, between 60 and 90 cm H2O and <60 cm H2O. A logistic regression study was performed in order to complete clinical predictors of ALPP < 60 cm H2O. Variables that were significant in the multivariate analysis were included in the score. RESULTS: We studied 158 patients: 65 presented ALPP > 90 cm H2O, 64 between 60-90 cm H2O and 29 <60 cm H2O. In the multivariate analysis, were presented as independent predictors of ALPP < 60 cm H2O, the presence of a fixed urethra (p 0.01), empty bladder test positive (p 0.02) and presence of symptoms grade III in the classification of Stamey (p 0.03). The accuracy of the test was: score 0, 42%; score 1, 58%; score 2, 81%. Receiver Operating Characteristic (ROC) analysis for the overall cutoff points revealed an area under the curve of 0,75. CONCLUSIONS: Presence of a fixed urethra, positive empty bladder test and patients with a high degree of SUI symptoms according to the Stamey score are independent clinical predictors of intrinsic sphincter deficiency. This score could represent a useful clinical tool to predict the presence of ALPP <60 cm H2O based on clinical parameters.

[Is there a correlation between abdominal leak pressure point, incontinence severity and quality of life in patients with stress urinary incontinence?] / Existe una correlación entre punto de presión de pérdida abdominal, severidad de incontinencia y calidad de vida?

OBJECTIVES: To evaluate if there is a correlation between the abdominal leak pressure point (ALPP) of the urodynamic study and several tools to evaluate severity and quality of life associated to stress urine incontinence (SUI). METHODS: Prospective correlation study of women referred to urodynamic study for stress urinary incontinence in Centro Urológico Profesor Bengió between September 2014 and October 2015. Anamnesis, physical examination (where the SUI was demonstrated), ICIQSF urine incontinence questionnaire and incontinence impact questionnaire (IIQ-7) were performed to every patient. Uroflowmetry and complete urodynamic study were performed in all cases. Intrinsic sphincter deficiency (ISD) was defined as ALPP value ≤ 60 cm H2O. The relation between abdominal leak pressure point (ALPP) and incontinence severity measurements and quality of life (daily protectors, Sandvik score, ISIQ-SF score and short IIQ7 score) was evaluated with the Spearman coefficient correlation. RESULTS: 105 females were studied. Mean ALPP was 84 H2O cm (30-170). 21 and 84 patients had ALPP values lower and higher than 60 H2O cm respectively. There were no differences between the groups when general and demographic characteristics were evaluated. No correlation between ALPP and incontinence severity measurements was demonstrated: daily protectors (ρ 0.10; p NS), Sandvik severity score (ρ 0.05; p NS), ISIQ-SF score (ρ 0.0004; p NS) and IIQ7 Score (ρ 0.06; p NS). When patients with IED (ALPP ≤ 60 cm H2O) and those without IED DEI (ALPP > 60 cm H2O) were analyzed, there was no statistically significant difference between the groups in the comparison according to severity and quality of life questionnaires. CONCLUSIONS: In this series, there is not a significant correlation between abdominal leak pressure point and severity and quality of life measurements in patients with stress urinary incontinence.

[Is CAPRA-S score a valid tool in our environment to predict biochemical recurrence, metastasis and death after radical prostatectomy?] / ?Es el Score CAPRA­S una herramienta válida en nuestro medio para predecir recurrencia bioquímica, metástasis y muerte posterior a prostatectomía radical?

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.

¿Existe una correlación entre punto de presión de pérdida abdominal, severidad de incontinencia y calidad de vida? / Is there a correlation between abdominal leak pressure point, incontinence severity and quality of life in patients with stress urinary incontinence?

OBJETIVOS: Evaluar si existe correlación entre el punto de presión de pérdida abdominal (ALPP) del estudio urodinámico y diversas herramientas para evaluar severidad y calidad de vida asociada a incontinencia de orina de esfuerzo (IOE). MÉTODOS: Estudio prospectivo y de correlación en mujeres derivadas para estudio urodinámico por incontinencia de orina de esfuerzo en el Centro Urológico Profesor Bengió entre septiembre de 2014 y octubre de 2015. A todas las pacientes se les realizó interrogatorio, examen físico (donde se evidenció IOE), cuestionario de incontinencia urinaria ICIQ-SF y cuestionario de impacto de incontinencia (IIQ-7). En todos los casos se les realizó uroflujometría y estudio urodinámico completo. Se definió deficiencia esfinteriana intrínseca (DEI) cuando el valor de ALPP fue ≤ a 60 cm H2O. La relación entre punto de presión de perdida abdominal (ALPP) y las mediciones de severidad de incontinencia y calidad de vida (protectores diarios, score de Sandvik, score ISIQ-SF y score IIQ7 corto) fue evaluada con el coeficiente de correlación de Spearman. RESULTADOS: Se estudiaron 105 mujeres. La media de ALPP fue 84 cm H2O (30-170). Los pacientes con ALPP menor y mayor a 60 cm H2O fueron 21 y 84 respectivamente. No existen diferencias entre los grupos al evaluar características generales y demográficas. No evidenciamos alguna correlación entre ALPP y las mediciones de severidad de incontinencia: protectores diarios (ρ 0,10; p NS), score de severidad de Sandvik (ρ 0,05; p NS), score ISIQ-SF (ρ 0,0004; p NS) y Score IIQ7 (ρ 0,06; p NS). Al analizar los pacientes con DEI (ALPP ≤ 60 cm H2O) de aquellos sin DEI (ALPP > 60 cm H2O) no evidenciamos diferencias estadísticamente significativas entre los grupos al ser comparados según cuestionarios de severidad y calidad de vida. CONCLUSIONES: En nuestra serie, no existe una correlación significativa entre el punto de presión de pérdida abdominal y las mediciones de severidad y calidad de vida de pacientes con incontinencia de orina de esfuerzo

Hallazgos patológicos y evolución en prostatectomía radical de pacientes candidatos para vigilancia activa / Pathological findings and follow-up of radical prostatectomy patients candidates for active surveillance

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...
