Background: LTx is the best treatment option for multinodular HCC and those with advanced liver dysfunction. Tumor progression occurs in 20-50% of pts on liver transplant list. TACE is increasingly used as locoregional therapy and as a bridge to LTx. We report here our single institutional experience with TACE using carbo and doxorubicin in pts with HCC awaiting LTx. Methods: Retrospective chart review was performed in all pts who had TACE between 2008 and June 2010. Our institutional protocol uses a fixed dose of carbo 300mg, doxorubicin 50mg, in 10ml of lipoidol solution. We analyzed pt demographics, etiologies of liver disease, Child-Pugh status, CLIP scores, size of tumor, alpha-fetoprotein (AFP), toxicity, length of stay, and transplantation statistics. Results: 32 pts (28 men) were treated with 39 TACE procedures. The median age was 57 (32-83). 28 of 32 had cirrhosis with Child's A/B/C 36/51/18% respectively. The major etiologies of cirrhosis were hepatitis C (HCV) 8, alcohol and HCV 19, alcohol 7; portal vein thrombosis in 8 pts. The median tumor size was 6.2 cm (range 2-12 cm) and 81% were multifocal CLIP score 0,1/2,>3 were 5/62/38%. There were no mortality within 30 days of TACE procedure. The majority of the pts were discharged after 24 hr observation; 6 pts require readmissions within 30days. There was no systemic hematologic toxicity. 11 pts had elevated AFP at baseline and 6/11 (54%) had >50 % reduction in AFP value. 11pts (34%) received Ltx; 3 pts came off the LTx list due to disease progression, 2 pts are still on transplant list, and 16pts not able to be listed. 42% of pts received sorafenib in addition to TACE. The median time from last TACE to LTx was 55 days and 4 pts received transplantation within 30days. Very good pathological treatment effect was observed in 8/11 explanted liver. Conclusions: Our regimen of TACE with carbo/doxorubicin appears to be a safe and tolerable approach for localized treatment as a bridge to liver transplantation. It has acceptable toxicity and is associated with good AFP and pathological responses. We plan to evaluate different baseline parameters for better pt selection.
