Se trata de un estudio observacional (no randomizado, no controlado) en el que estudiaron el uso de Aspirina y de otros AINE en 28.283 mujeres posmenopáusicas que participaron en la encuesta del Iowa Women´s Health Study entre 1992 y 1999.
Los investigadores encontraron que las mujeres que tomaban Aspirina tenían un índice de cáncer pancreático un 43% inferior que aquellas que no tomaban este fármaco. Asimismo, el riesgo de padecer la patología disminuía en paralelo al mayor consumo de Aspirina.
En concreto, de los 80 casos de cáncer de páncreas identificados en el estudio, 33 fueron mujeres que nunca habían usado Aspirina y otro 27% lo hacían menos de una vez por semana. El riesgo relativo, ajustado tras un análisis multivariante, asociado al uso o no uso habitual de Aspirina fue de 0,57 (intervalo de confianza del 95%: de 0,36 a 0,90). En este estudio, publicado en el “Journal of the National Cancer Institute”, no se encontró ninguna asociación entre cáncer de páncreas y el resto de AINE.
