NEOPLASIAS DE LA PRÓSTATA, ANTAGONISTAS DE ANDRÓGENOS, OSTEOPOROSISResumen
Introducción: el cáncer de próstata (CP) es el tumor maligno más frecuente en hombres en Uruguay. La terapia de deprivación androgénica (TDA) es una herramienta valiosa para su tratamiento. Si bien es altamente eficaz, este tratamiento tiene diversos efectos no deseados, entre los que se encuentra la disminución de la densidad mineral ósea.
Material y método: realizamos un estudio longitudinal, observacional y prospectivo cuyo objetivo fue determinar si existe disminución de la densidad mineral ósea en los pacientes que reciben TDA para el CP. Se incluyeron pacientes portadores de CP en cualquier estadio que iniciarían tratamiento con TDA en el Servicio de Oncología del Hospital de Clínicas de Montevideo, Uruguay, en el período setiembre de 2012 a agosto de 2013, en quienes se realizó una densitometría ósea (DMO) previo al inicio de la TDA (DMO1) y se repitió a los seis meses de recibir la primera dosis de tratamiento hormonal (DMO2). Para cada región analizada se compararon las medias de densidad ósea medida en g/cm2 en la DMO1 vs DMO2.
Resultados: se hizo seguimiento a diez pacientes con una edad mediana de 77 años. Se observó disminución significativa de la densidad mineral ósea en vértebras L3 y L4 (L3: 1.268 g/cm2 a 1.225 g/cm2 p=0,01; L4: 1.247 g/cm2 a 1.227g/cm2 p=0,005), mientras que en los otros puntos evaluados (L1, L2, cuello de fémur y cadera total) también hubo una disminución pero sin alcanzar significancia estadística.
Conclusiones: confirmamos que la TDA disminuye la densidad mineral ósea por lo menos en vértebras lumbares 3 y 4 en un relativamente corto plazo (seis meses). Este efecto adverso debe evaluarse, identificarse y prevenirse oportunamente para evitar complicaciones mayores.
