Table 2 Values of the LKB-model parameters, the corresponding biological-endpoints and the LQ-model parameter for all OARs

From: Estimation of the risk for radiation-induced liver disease following photon- or proton-beam radiosurgery of liver metastases

OAR n m TD 50 (Gy) Endpoint α/β (Gy) Sources
Skin 0.38 0.14 39 Radiation-induced skin toxicity 3a Pastore et al. (2016) [31]
Lung 1 0.41 29.9 Symptomatic radiation pneumonitis 3 Semenenko & Li (2008) [32]
Liver 0.97 0.12 45.8 Radiation-induced liver disease (RILD) 2 Dawson et al. (2002) [2]
Spinal cord 0.05 0.175 66.5 Radiation myelitis 0.87b Burman et al. (1991) [33]
Right kidney 0.70 0.10 28 Clinical nephritis 3a Burman et al. (1991) [33]
  1. aValues of the assumed α/β parameter for these OARs; bthe value of the α/β parameter for the spinal cord was taken from Schultheiss (2008) [34]
