Künstliche Intelligenz: Chancen und Grenzen
摘要
Artificial intelligence (AI) can support cancer care in many different ways. Classic, nongenerative AI is already established in oncology, as narrow applications (“one problem, one solution”) such as polyp and lung-nodule detection or automated differential blood counts are clearly measurable, prospectively testable, and validatable under current regulations. Large language models (LLMs) now allow for a completely new and broader usage of AI, as they offer substantial documentation relief (transcription, structuring) and real-time clinical decision-support systems (CDSS) that connect patient data to guidelines or studies or can match patients to clinical trials. Risks arise from model misreasoning (shortcut learning), hallucinations, and overconfirmation, as well as from shadow use, privacy/liability, vendor lock-in, de-skilling, and fairness. We outline pragmatic guardrails such as source-grounded recommendations; human-in-the-loop review; explicit uncertainty; alternatives; auditability; and safe, electronic health record (EHR)-integrated pathways.
