Un nuevo estudio encuentra que la IA puede ayudar a mejorar las predicciones de riesgo de cáncer de mama

Publicado

el

Un nuevo estudio muestra otra forma en que la inteligencia artificial está entrando en el campo de la medicina y, potencialmente, mejorando las prácticas existentes para predecir el riesgo de cáncer de mama.El estudio, que se publicó el martes en Radiology, una revista revisada por pares, encontró que los algoritmos de IA superaron el modelo de riesgo clínico estándar para predecir el riesgo de cáncer de mama a cinco años .Los modelos de riesgo como el puntaje de riesgo clínico del Consorcio de Vigilancia del Cáncer de Mama (BCSC), que utilizan información autoinformada y otra información del paciente, incluida la edad, los antecedentes familiares y más, generalmente se usan para calcular el riesgo de cáncer de mama de una mujer.

«Los modelos de riesgo clínico dependen de la recopilación de información de diferentes fuentes, que no siempre está disponible o no siempre se recopila», dijo en un comunicado de prensa el investigador principal, el Dr. Vignesh A. Arasu, científico investigador y radiólogo en ejercicio en Kaiser Permanente del Norte de California. «Los avances recientes en el aprendizaje profundo de la IA nos brindan la capacidad de extraer de cientos a miles de características mamográficas adicionales».En el estudio retrospectivo, se analizaron miles de mamografías y cinco algoritmos de IA generaron puntuaciones de riesgo de cáncer de mama durante un período de cinco años. Luego, esas puntuaciones se compararon entre sí y con la puntuación de riesgo clínico de BCSC.»Los cinco algoritmos de IA funcionaron mejor que el modelo de riesgo BCSC para predecir el riesgo de cáncer de mama de 0 a 5 años», dijo Arasu. «Este fuerte desempeño predictivo durante el período de cinco años sugiere que la IA está identificando tanto los cánceres perdidos como las características del tejido mamario que ayudan a predecir el desarrollo futuro del cáncer».Si bien algunas instituciones ya están utilizando la IA para ayudar a detectar el cáncer en las mamografías, estos hallazgos sugieren que la IA puede ser una herramienta vital para ayudar con la puntuación de riesgo futura de un paciente, que la IA tarda unos segundos en generar, según el comunicado.

«La IA para la predicción del riesgo de cáncer nos ofrece la oportunidad de individualizar la atención de cada mujer, que no está disponible sistemáticamente», dijo Arasu. “Es una herramienta que podría ayudarnos a brindar medicina personalizada y de precisión a nivel nacional”.
