Resumen
Introducción y objetivos Existen múltiples opciones de tratamiento en pacientes con cáncer de próstata resistente a la castración, entre ellas el Dietilestilbestrol (DES) sin embargo, su uso es controversial. Este estudio tiene como objetivo determinar la eficacia y seguridad del DES, en el tratamiento de pacientes con cáncer de próstata resistente a la castración en nuestra población.
Métodos y Materiales Se realizó un estudio de corte transversal, incluyendo los pacientes con cáncer de próstata resistente a la castración que recibieron tratamiento con DES. Se realizó un análisis demográfico, bivariado, tomando como desenlace la respuesta del PSA (Ausente, Completa o Parcial), el tiempo medio de progresión del PSA y la presencia de eventos adversos asociados al medicamento.
Resultados Noventa y un pacientes incluidos al final del estudio. La distribución de respuesta del PSA fue así: Respuesta en 57 (63,7%) pacientes, (Completa 28% - 31,1% y parcial 29% - 32,2%). Ausente en 33 (36,7%) pacientes. El análisis bivariado no evidenció asociación entre las variables y los desenlaces propuestos. El tiempo medio de progresión del PSA fue de 10,43 meses (Log-rank p = 0.001), no se encontraron diferencias estadísticamente significativas para el tiempo medio a progresión en asociación con la respuesta al PSA (respuesta o ausente y la presencia de enfermedad metastásica), Log-rank p = 0,789, Log-rank p = 0,218, Log-rank p = 0,780 respectivamente. La tasa de complicaciones asociadas a DES fue del 4,4% y correspondió en todos los casos a trombosis venosa profunda.
Conclusiones El DES en pacientes con cáncer de próstata resistente a la castración continúa siendo una herramienta de tratamiento eficaz y con baja tasa de eventos adversos en nuestra población.
Abstract
Introduction and Objectives There are multiple treatment options in patients with castration-resistant prostate cancer, including diethylstilbestrol (DES), but its use is controversial. This study aims to determine the efficacy and safety of DES in the treatment of patients with castration resistant prostate cancer in our population.
Methods and Materials A cross-sectional study was performed, including patients with castration resistant prostate cancer who were treated with DES. A demographic analysis was performed, bivariate analysis, taking as outcome PSA response (Complete or partial), the median time to PSA progression and the presence of adverse events associated with the drug.
Results 91 patients included at the end of the study. The distribution of PSA response was so; Response in 57 (63.7%) patients (Full 28 to 31.1% and partial 29 to 32.2%). Absent in 33 (36.7%) patients. Bivariate analysis evidenced no association between the variables and proposed outcomes. The median time to PSA progression was 10.43 months (log-rank p = 0.001), no statistically significant differences in the average time to progression was found in association with PSA response (response or absent and the presence of disease metastatic), Log-rank p = 0.789, log-rank p = 0.218, log-rank p = 0.780 respectively. The rate of complications associated with DES was 4.4% and corresponded in all cases to deep vein thrombosis.
Conclusions DES in patients with resistant prostate cancer castration continued to be an effective choice of tool of treatment with a low rate of adverse events in our population.
