With the rise of artificial intelligence future clinical support systems based on PRO hold the promise of transforming traditional decision -making models further optimizing healthcare service quality. Therefore based on expert opinions and existing evidence this consensus offers recommendations for the standardized application of ePRO systems in clinical practice and research aiming to promote efficiency and comprehensiveness of nutritional management in oncology settings.
