Stereotactic Body Radiotherapy for Patients With Unresectable Primary Hepatocellular Carcinoma: Dose-Volumetric Parameters Predicting the Hepatic Complication

The progression of CP class after SBRT limits other additional local treatments and also reflects the deterioration of hepatic function. Therefore, it would be important to note that the presence or absence of the progression of CP class is a dose-limiting factor. The total liver volume receiving <18 Gy should be greater than 800 cm3 to reduce the risk of the deterioration of hepatic function.
