ABSTRACT

OBJETIVO: El cáncer de próstata (CP) avanzado es una entidad frecuente. Los objetivos de este trabajo son la presentación de una serie de pacientes con CP en tratamiento con Terapia de Deprivación Androgénica (TDA) en práctica clínica habitual y la determinación de parámetros asociados al desarrollo de resistencia a la castración (CPRC). MATERIAL Y MÉTODOS: Estudio multicéntrico, observacional, retrospectivo que analiza pacientes tratados con TDA desde enero 2016 hasta enero 2017. Análisis descriptivo de las variables clínicas más relevantes, análisis univariante y supervivencia libre de progresión mediante test Kaplan-Meier. RESULTADOS: Muestra 952 pacientes. Al diagnóstico del CP edad mediana 74 años. Mediana de PSA al diagnóstico de CP 23 ng/ml, al inicio TDA 20,2 ng/ml. El 80,2% de pacientes tenían biopsia al diagnóstico del CP: 28,2% grado pronóstico Gleason grupo 1, 38,7% grados 2 y 3 y 33,1% grados 4 y 5. Tratamiento inicial del CP: 75,9% TDA, prostatectomía radical 8,4% y radioterapia 15,1%. De los 952 pacientes, 281 (29,6%) cumplían criterios de CPRC. En este grupo el 21,7% alcanzó PSA indetectable (<0,1 ng/ml) con la TDA 20,2 frente al grupo no CPRC en el que lo alcanzaron el 59,9%. Encontramos mayor probabilidad de progresión a CPRC en pacientes con PSA al diagnóstico de CP > 30 ng/ml (p = 0,000, OR 2,78), grado pronóstico Gleason grupos 4-5 (p = 0,000, OR 2,33) y en aquellos que no alcanzan PSA indetectable tras TDA (p < 0,01, OR 3,32) variables que se relacionan con los tiempos de progresión a CPRC y especialmente al estadio metastásico. CONCLUSIONES: Se presenta una serie de pacientes CP avanzado en tratamiento con TDA que muestra heterogeneidad de características y de manejo según práctica clínica habitual. En nuestra serie el PSA elevado al diagnóstico, histología desfavorable y no alcanzar un PSA< 0,1 ng/ml tras la TDA se presentan como indicadores de progresión a estadio CPRC


OBJECTIVES: Advanced prostate cancer (PC) is a frequent entity. The objectives of this paper are the presentation of a sample of patients with PC undergoing treatment with androgen deprivation therapy (ADT) in usual clinical practice and the determination of parameters associated with the development of resistance to castration (CRPC). MATERIAL AND METHODS: Multicenter, observational, retrospective study that analyzes patients treated with ADT from January 2016 to January 2017. Descriptive analysis of the most relevant clinical variables and univariante analysis and progression times by Kaplan-Meier test. RESULTS: Sample of 952 patients. At PC diagnosis median age 74 years. Median PSA at PC diagnosis 23 ng/ml, when begining ADT 20.2 ng/ml. 80.2% of patients were biopsied at PC diagnosis: 28.2% Gleason score group 1, 38.7% groups 2 and 3 and 33.1% groups 4 and 5. Initial treatment of PC: 75.9% ADT, radical prostatectomy 8.4% and radiotherapy 15.1%. Of the 952 patients, 281 (29.6%) fulfilled CRPC criteria. In this group 21.7% achieved undetectable PSA (< 0.1 ng/ml) with ADT compared to the non-CRPC group in which it was 59.9%. Increased probability of progression to CRPC in: PSA >30ng/ml at PC diagnosis (p = 0.000, OR 2.78), Gleason score group 4-5 (p = 0.000, OR 2.33), and not to reach undetectable PSA after ADT (p < 0.001, OR 3.32). The initial ADT group presents progression to metastatic CRPC more rapidly in unfavourable histology and when not reached undetectable PSA after ADT. CONCLUSIONS: We present a sample of patients with advanced PC in treatment with ADT that shows heterogeneity in usual clinical practice. In our sample, elevated PSA at PC diagnosis, unfavorable histology and failure to achieve a PSA <0.1ng/ml after ADT is presented as an indicator of progression to the CRPC stage

ABSTRACT

Renal lithiasis is known for its high incidence and prevalence, but mainly for its morbidity and recurrence. Despite a good indication and appropriate surgical treatment, the essential problem, the origin of the formation of the stones, generally persists and it is not uncommon that patients suffer multiple treatments and discomfort secondary to ancillary measures normally used to prevent complications. It is widely known, for consistency, that a prophylactic treatment with general or, in a smaller group of patients, specific measures are appropriate to diminish recurrences. Nevertheless, prophylaxis is not usually used by many urologists and, on top of that, in the majority of those cases when it is taken into consideration, it is the patient who fails for inadequate treatment compliance. It is very important, in any of our conversations with the urinary lithiasis' patient in relation with the disease, that the urologist provides a proper and detailed information about all its features, from diagnosis to active treatment and possible complications and, of course in those cases where prophylaxis is going to be essential to avoid new unpleasant episodes of pain and associated surgical interventions, emphasizing that improving his/her quality of life depends, to a great extent, on the patient himself. In this article, considering the existing evidence and personal experience, we intend to detail those behaviors we should take into consideration to facilitate the patient both therapeutic decisions and a positive attitude towards his/her disease, with the aim to control it in the best possible way.

ABSTRACT

La litiasis renal es conocida por su alta incidencia y prevalencia, pero sobre todo por su morbilidad y recurrencia. A pesar de una buena indicación y un tratamiento quirúrgico apropiado, el problema de fondo, es decir el origen la formación de los cálculos, normalmente sigue existiendo y no es raro que los pacientes sufran múltiples tratamientos y molestias secundarias a las maniobras auxiliares que normalmente empleamos para prevenir complicaciones. Es de sobra sabido, por coherente, que un tratamiento profiláctico con medidas generales o, en un menor grupo de pacientes, específicas son convenientes para disminuir las recidivas. Sin embargo, la profilaxis no suele ser empleada por una buena parte de los urólogos y, por si fuera poco, en una buena parte de aquellos casos en los que sí se tiene en cuenta, es el paciente el que falla por inadecuada adherencia al tratamiento. Es de gran importancia, en cualquiera de las conversaciones con el paciente litiásico relacionadas con su enfermedad, que el urólogo le proporcione una correcta y detallada información sobre todos los aspectos de la misma, desde el diagnóstico al tratamiento activo y posibles complicaciones y, desde luego en aquellos casos en los que la profilaxis vaya a ser fundamental para evitar nuevos episodios desagradables de dolor e intervenciones quirúrgicas asociadas, haciendo hincapié en que del propio paciente depende, en buena medida, que mejore su calidad de vida. En este artículo se pretende enumerar aquellas actitudes que debemos tener en cuenta, contando con la evidencia existente y la experiencia personal, para facilitar al paciente tanto las decisiones terapéuticas como una actitud positiva del mismo hacia su propia enfermedad, con el propósito de controlarla de la mejor manera posible
