“…Mortality of REILD may reach up to 30% [ 102 ]. A radiation dose-to-liver volume ratio >0.8 GBq/L, an elevated dose to normal liver (>50 Gy), pre-existing liver disease, previous chemotherapy, whole liver treatment, extensive tumor burden, and elevated bilirubinemia (>2 g/dL) are identified risk factors of REILD [ 97 , 102 , 103 , 104 , 105 , 106 ].
