Abstract
Orthotopic liver transplantation (OLT) is the most effective treatment for hepatocellular carcinoma (HCC) in patients with underlying cirrhosis and portal hypertension. Availability of OLT is limited by donor-organ shortages, which increase patient waiting time until OLT. A variety of bridging therapies (BT) have been used to halt tumor progression in patients on the OLT waiting list. Despite complete radiologic responses following BT, viable tumor is often present in explants. Treatment outcomes were evaluated in 50 patients who had a total of 125 BT for treatment of 93 nodules. Success of BT was assessed by radiologic response compared to histopathological examination of explanted livers. Pre-transplant treatments included: transcatheter arterial chemoembolization (TACE), alcohol ablation (ETOH), radiofrequency ablation (RFA), microwave ablation (MWA), selective internal radiation therapy (SIRT) and stereotactic body radiation therapy (SBRT). Fifty-nine (64%) nodules had a complete radiographic response to therapy; however, only 28 nodules (30%) had complete tumor necrosis (CTN) on explant examination. Ten nodules with CTN were treated with TACE alone. Seven of the 28 nodules with CTN were treated with TACE and RFA. Three of ...Continue Reading
