ABSTRACT

OBJECTIVE: To address the effect of therapy options and other factors on the natural history of localized prostate cancer (PCa). METHODS: Men with diagnosed clinically localized PCa who underwent radical prostatectomy (RP), radiotherapy (RT) or watchful waiting (WW). Rates of biochemical progression (BQP) and clinical progression (CLP) were calculated. The effects of therapy, initial PSA, presence of palpable tumor and Gleason score were assessed with Kaplan-Meier analysis and log-rank test. Similar methods were used to study overall and disease-specific survival. RESULTS: A total of 228 patients were studied (135 underwent RP, 46 RT, and 47 WW). Median followup time was 2.5 years. Forty patients presented with BQP. The probability of being free from BQP after 2 and 5 years was 76.8% and 57.9% respectively for the whole population, 70.9% and 57.6% for RP patients, 100% and 100% for RT, and 87.1% and 47.2% for WW (p = 0.031). Nineteen patients presented with CLP, with no significant differences with regard to therapy option. A poorly differentiated Gleason score favoured the probability of presenting with CLP (p = 0.022) and shift to metastatic disease (p < 0.001). No cancer-specific mortality was recorded in the studied population. CONCLUSIONS: Short and medium-term prognosis is excellent for localized prostate cancer in terms of survival. Nevertheless, some patients show a higher risk of progressing to metastatic disease (poorly differentiated Gleason score).

ABSTRACT

OBJETIVO: Conocer el impacto de la alternativa terapéutica y de otros factores sobre la historia natural del cáncer de próstata (CaP) localizado. MÉTODOS: Pacientes con CaP clínicamente localizado sometidos a prostatectomía radical (PR), radioterapia (RT) u observación (OBS). Se calcularon las tasas de progresión bioquímica (PBQ) y clínica (PCL). Se evaluaron los efectos del tratamiento, del PSA al diagnóstico, de la presencia de tumor palpable y del score de Gleason mediante análisis Kaplan- Meier y test log-rank. Del mismo modo se estudiaron la mortalidad global y la cáncer específica. RESULTADOS: Se estudiaron 228 pacientes (135 sometidos a PR, 46 a RT, y 47 a OBS). La mediana del tiempo de seguimiento fue de 2,5 años. Cuarenta pacientes presentaron PBQ. La probabilidad de permanecer libre de PBQ a los 2 y 5 años fue de 76,8% y 57,9% respectivamente para la serie completa, 70,9% y 57,6% para PR, 100% y 100% para RT, y 87,1% y 47,2% para OBS (p=0,031). Diecinueve pacientes presentaron PCL, no observándose diferencia significativa respecto del tratamiento efectuado. Un score de Gleason pobremente diferenciado influyó en la probabilidad de presentar PCL (p=0,022) y en la evolución a enfermedad metastásica (p<0,001). No se registró mortalidad cáncer-específica en la población estudiada. CONCLUSIONES: El pronóstico a corto y medio plazo del cáncer de próstata localizado es, en términos de supervivencia, excelente. No obstante, algunos enfermos presentan un mayor riesgo de desarrollar enfermedad metastásica (Gleason pobremente diferenciado) (AU)

ABSTRACT

INTRODUCTION AND OBJECTIVE: Surgical repair is the most effective option for the treatment of stress urinary incontinence (SUI) between the different therapeutical options available at present. The main objective of our study is to compare the outcome of the different techniques employed in the treatment of SUI in our setting. METHOD: We have performed a retrospective analysis of the patients who underwent surgical intervention for SUI between 1991 to 1999 (213 surgical interventions in 194 patients) clustering the surgical procedures into three groups: abdominal, abdomino-vaginal, and sling procedures. The results of the treatment were defined as follows: total continence, significant improvement and insufficient improvement. Comparison of continence rates was performed with chi 2 test and Fisher's exact test. Association between qualitative variables was also evaluated by means of chi 2 test. Multivariate analysis of predictive factors was performed with a Cox model. The outcome was also evaluated by Kaplan-Meier's curves, and comparisons made with log-rank test. Statistical significance level was established for p < 0.05. RESULTS: Global cure rate at 24 months was 54.5% (116 patients). Significant improvement was observed in 33 patients (15.5%), and insufficient improvement was seen in 64 patients (30%). The most frequent postoperative complications were suprapubic pain (33%), acute urinary retention (26%), significant postvoiding residual urine (24%) and wound seroma or infection (20%). None of the analyzed factors (age, weight, number of births, preoperative pads, postoperative acute urinary retention, and need for postoperative bladder clean intermittent catheterization were independent predictive factors for postoperative continence. The actuarial analysis with Kaplan-Meier curves shows no statistical differences between the studied techniques (log rank p = 0.41). Sling techniques presented with a superior rate of most postoperative complications. CONCLUSIONS: The cure rate of our serie was 54.5% at 24 months, with a 70% of clinically satisfactory responses. With regard to continence status, it seems that there is not a better surgical technique in our hands, presenting sling techniques with a higher rate of postoperative complications. We could not find no pre o postoperative independent factors as predictors of postoperative continence.

ABSTRACT

INTRODUCCIÓN: La corrección quirúrgica es actualmente el método más efectivo de tratamiento para la incontinencia urinaria de esfuerzo (IUE) de entre las diferentes opciones terapéuticas de las que se dispone en la actualidad. El objetivo de este trabajo consiste en comparar la eficacia de los distintos grupos de técnicas empleadas para el tratamiento de la IUE en nuestras pacientes. MATERIAL Y MÉTODO: Hemos llevado a cabo un análisis retrospectivo de las pacientes intervenidas en nuestro Servicio por IUE durante el periodo comprendido entre abril de 1991 y julio de 1999 (213 intervenciones en 194 pacientes), agrupando los procedimientos en 3 grupos: técnicas abdominales, técnicas abdomino-vaginales, y técnicas de cabestrillo. La tasa de éxito de la intervención fue valorada mediante tres categorías: continencia total, mejoría clínicamente significativa, y ausencia de mejoría. La comparación bivariante de proporciones se realizó mediante la prueba exacta de Fisher y el test de Chi-cuadrado. La asociación de variables cualitativas se evaluó mediante el test de Chi-cuadrado: se utilizó un modelo de Cox para el análisis multivariante de los factores predictores de continencia, y curvas de Kaplan-Meier para la evaluación de la supervivencia de la continencia post-operatoria. Para todos ellos se tomó como nivel de significación estadística una p<0,05. RESULTADOS: La tasa de continencia total de nuestra serie fue del 54,5 por ciento (116 pacientes continentes) a los 2 años. En el grupo de mejoría clínica significativa fueron incluidas 33 pacientes (15,5 por ciento) y en el grupo de pacientes sin mejoría 64 pacientes (30 por ciento) (Figs. 3 y 4). Las complicaciones más frecuentes fueron la presencia de dolor suprapúbico (33 por ciento), la infección de la herida (20 por ciento), la retención de orina post-operatoria (26 por ciento), y la presencia de residuo post-miccional significativo (24 por ciento). Ninguno de los múltiples factores analizados, se mostraron como factores predictivos independientes para la continencia post-operatoria. En el análisis actuarial, tras la comparación de las curvas de Kaplan-Meier correspondientes a cada técnica, objetivamos que no existen diferencias entre las distintas técnicas (logrank; p=0,41) presentando la técnica de sling un mayor número de complicaciones. CONCLUSIONES: La tasa de continencia total post-quirúrgica de nuestra serie es de un 54,5 por ciento a los dos años, encontrando un total de 70 por ciento de respuestas clínicamente satisfactorias. No parece existir una técnica claramente superior a las demás en cuanto a eficacia para nuestras pacientes, presentando la técnica de sling un porcentaje superior de complicaciones. No hemos encontrado factores pre o post-operatorios que influyan de modo independiente en la predicción de la continencia post-quirúrgica (AU)
