Currently, there are no prospective studies evaluating the efficacy of concomitant gem-cis and RT for locally advanced IHC regarding disease response or post-operative intrahepatic disease recurrence. Prior full dose external beam RT is an accepted contraindication to liver resection due to development of advanced fibrosis and intrahepatic biliary sclerosis. However, no studies have evaluated the influence of preoperative LDFRT on outcomes after partial hepatectomy. Case reports of safe liver resection after antecedent radioembolization suggest that LDFRT may not adversely affect postoperative outcomes. LDFRT to the entire liver and portal lymph node basin is advantageous compared to tumor directed therapy as the former treats occult disease representing the most common site of disease recurrence after partial hepatectomy and progression after chemotherapy.
