In our experience, the primary obstacle precluding the widespread use of orthotopic liver transplantation (OLT) for definitive therapy of hepatocellular carcinoma (HCC), even for early-stage disease, is preventing tumor recurrence. Chemoembolization is an attractive strategy to minimize tumor progression before OLT because of its shown antitumor effect, ability to be repeated, and minimal systemic toxicity. Thus, this pilot study was undertaken to determine the tolerability and treatment outcomes of pretransplantation chemoembolization of HCC followed by OLT. Between 1992 and 1997, 27 patients with HCC who had cirrhosis, no extrahepatic metastasis, less than three tumor nodules of less than 5 cm each, and no evidence of vascular invasion on preoperative imaging studies were enrolled onto the protocol. Chemoembolization was performed using Ivalon particles with mitomycin, doxorubicin, and cisplatin. Twenty-four patients completed the protocol with chemoembolization and a liver transplant. The mean United Network of Organ Sharing waiting time was 167 days. Chemoembolization was well tolerated. On examination of the explanted liver, the majority of patients had a single lesion, mean tumor size was 3.66 cm (range, 1.5 to 6 cm), and the majority of patients had stage II disease. None of the transplant recipients has developed recurrent HCC (mean follow-up, 29.2 months; range, 9 to 55 months). The 1-and 2-year disease-free survival rates are 91% and 84%, respectively. In conclusion, chemoembolization followed by OLT is well tolerated and associated with excellent outcomes in selected patients with HCC.
Copyright 1999 by the American Association for the Study of Liver DiseasesH epatocellular carcinoma (HCC) is one of the most common malignant tumors occurring in men worldwide, with an estimated annual incidence of 1 million cases. In the United States, HCC ranks as the 22nd most common form of cancer, with an annual incidence of approximately 2:100,000. 1 HCC is associated with chronic hepatitis B carrier state, chronic hepatitis C, cirrhosis from a wide variety of causes, iron-overload states, and exposure to aflatoxins. In one study, the natural history of 102 patients with cirrhosis with HCC who were not treated within prospective randomized trials was investigated. 2 After a median follow-up of 17 months, the 1-, 2-, and 3-year survival rates were 54%, 40%, and 28%, respectively. The adverse natural history attests to the need for establishing effective therapies for this aggressive malignancy.A variety of therapeutic modalities have been tried in the treatment of advanced HCC, including systemic chemotherapy, hepatic artery infusion of chemotherapeutic agents, hepatic artery embolization, hormonal therapy, and radiation therapy, all without long-term success. [3][4][5][6][7][8] Although surgical resection of HCC is considered the treatment of choice whenever technically feasible, long-term results after resection of even small tumors in patients with cirrhosis are disappointing; the 5-year recurrence rate is 52% a...
