PANDA IA  logra detectar cáncer de páncreas en fase inicial con alta precisión

Un equipo de investigación chino ha desarrollado PANDA, una plataforma de inteligencia artificial (IA) capaz de identificar el cáncer de páncreas en su fase inicial con gran precisión mediante imágenes de rayos X. Desarrollado por la Academia Damo de Alibaba, este enfoque de aprendizaje profundo magnifica e identifica características patológicas sutiles en imágenes de tomografía computarizada, facilitando la detección temprana de este tumor altamente maligno.

PANDA se entrenó inicialmente con un conjunto de datos de 3.208 pacientes de un mismo centro. Según un estudio publicado en Nature Medicine, la herramienta de IA alcanzó una sensibilidad del 94,9% y una especificidad del 100% en una cohorte de prueba interna de 291 pacientes de la Institución de Enfermedades Pancreáticas de Shanghai. Posteriormente, el modelo fue validado en cohortes externas multicéntricas de 5.337 pacientes, mostrando una sensibilidad del 93,3% y una especificidad del 98,8%, superando al rendimiento promedio de un radiólogo.

Con más de 500,000 utilizaciones clínicas y solo un falso positivo por cada 1,000 casos, los investigadores consideran que PANDA podría convertirse en una herramienta efectiva para el cribado a gran escala del cáncer de páncreas, ofreciendo esperanza para la detección temprana y potencialmente curable de esta enfermedad.
