WebThis means that when you have dose enough to achieve 95% tumour control, that same dose might only result in an NTCP of 10% (again, it's relative, but the NTCP is usually always lower than the TCP for the same dose). And the difference between these two curves (at some given point on the curve, usually 50% probability) is the therapeutic ratio. Web1 giu 2024 · Fig. 1. Normal tissue complication probability (NTCP) versus generalized equivalent uniform dose (gEUD) as computed from a mathematical function - Lyman-Kutcher-Burman (LKB) model. Blue asterisks indicate the considered toxicity outcome (level “1” = patients with toxicity; level “0” = patients without toxicity).
