Abbreviations: LTP, local tumor progression; IDR, intrahepatic distance recurrence; ER, extrahepatic recurrence; TACE, transarterial chemoembolization; LR, liver resection; DOD, dead as a result of disease; AWD, alive with disease; Lost, lost to follow-up. † This patient was confirmed to have IDR 4.0 months after SBRT and received TACE as a salvage therapy. LTP was confirmed 14.9 months after SBRT, and TACE was performed on this patient again.
