Surgical treatment of hepatocellular carcinoma in North America: can hepatic resection still be justified?

Abstract

Background: The incidence of hepatocellular cancer (HCC) is increasing dramatically worldwide. Optimal management remains undefined, especially for well-compensated cirrhosis and HCC.

Study design: This retrospective analysis included 5 US liver cancer centers. Patients with surgically treated HCC between 1990 and 2011 were analyzed; demographics, tumor characteristics, and survival rates were included.

Results: There were 1,765 patients who underwent resection (n = 884, 50.1%) or transplantation (n = 881, 49.9%). Overall, 248 (28.1%) resected patients were transplant eligible (1 tumor <5 cm or 2 to 3 tumors all <3 cm, no major vascular invasion); these were compared with 496 transplant patients, matched based on year of transplantation and tumor status. Overall survivals at 5 and 10 years were significantly improved for transplantation patients (74.3% vs 52.8% and 53.7% vs 21.7% respectively, p < 0.001), with greater differences in disease-free survival (71.8% vs 30.1% at 5 years and 53.4% vs 11.7% at 10 years, p < 0.001). Ninety-seven of the 884 (11%) resected patients were within Milan criteria and had cirrhosis; these were compared with the 496 transplantation patients, with similar results to the overall group. On multivariate analysis, type of surgery was an independent variable affecting all survival outcomes.

Conclusions: The increasing incidence of HCC stresses limited resources. Although transplantation results in better long-term survival, limited donor availability precludes widespread application. Hepatic resection will likely remain a standard therapy in selected patients with HCC. In this large series, only about 10% of patients with cirrhosis were transplant-eligible based on tumor status. Although liver transplantation results are significantly improved compared with resection, transplantation is available only for a minority of patients with HCC.
