Adjuvant Stereotactic Body Radiation Therapy After Trans-arterial Chemoembolization in Hepatocellular Carcinoma

1-2 session TACE before SBRT according to the preference of the interventional radiologist. Goal of TACE is the complete emnbolization of the HCC-nodules. It is allowed to use both conventional TACE (cTACE) and drug-eluting beads TACE (DEB-TACE) according to the interventional radiologist preference.

"SBRT should be 1 month after last TACE. This can be extended till 2 months if indicated. However, prolongation of the gap between TACE and SBRT is not encouraged.~Treatment center should choose one of fractionation schedule mentioned allowed in the study, in order to achieve a balance between dose applied for tumor control and constraints for OAR PTV Dose in 5 / 8 fractions (Gy) EQD2 (α/β 10Gy) 5x 8-6 Gy @ 83% isodose = 40-30 Gy (60-40 Gy) 8 x 6-4.5 Gy @ 83% isodose = 48-36 Gy (64-43.5 Gy)"
