Asociación del consumo de Té y Café con riesgo de cáncer de próstata

27-04-2017

Se adelantó un estudio de casos y controles con el objetivo de explorar la relación entre el consumo de té y café con el riesgo de cáncer de próstata (CP). La investigación se realizó en King County, Washington, EE.UU. Se incluyeron 1001 casos de CP diagnosticados entre 2002-2005. 942 controles fueron incluidos pareando por grupos etarios de 5 años. Una regresión logística no condicionada fue utilizada para estimar la Razón de Momios (odds ratio OR) empleando intervalos de confianza del 95 % (IC). Se consideraron variables confusoras que pudieran modificar la asociación. Entre los controles, 19 % y 58 % consumían al menos una taza por día de té y café, respectivamente. Con respecto al consumo de té, se incluyeron 892 casos y 863 controles. Para los hombres, comparando la categoría más alta de consumo con la más baja (≥2 tazas/día contra ≤1 taza/semana) se observó una asociación significativa entre el consumo de té y una reducción del riesgo de CP (OR ajustado 0.63 IC 95%: 0.45, 0.90; P para tendencia = 0.02). Las estimaciones de riesgo no variaron considerablemente según el grado de Gleason o el estadio de la enfermedad. Por otro lado, el consumo de café no resultó asociado con el riesgo de CP total o en subgrupos según grado del tumor o estadio. En conclusión, en este estudio el consumo de té resulto inversamente asociado con el riesgo de CP.
