Hepatocellular carcinoma: multimodality management

Abstract

Background: Hepatocellular carcinoma is one of the most common tumors worldwide. Surgical resection has been the standard treatment but can only be applied to a small percentage of patients. In recent years, several other treatment options, including ablative procedures and transplantation, have been used in patients with hepatocellular carcinoma.

Methods: For 6 years, 110 patients with hepatocellular carcinoma were managed at the Medical College of Wisconsin. Fifty-five patients received only chemotherapy (n = 5) or palliative treatment (n = 50) because of advanced cirrhosis (P <.03) or tumor. Thirty-one patients had tumor ablation with percutaneous ethanol injection, cryoablation, radiofrequency ablation, or arterial chemoembolization. Twenty-eight patients underwent surgical resection (n = 18) or hepatic transplantation (n = 10). Relatively more patients (38%; P <.001) were treated with ablation in the second period of the study (1998-2000).

Results: Thirty-day mortality was 3% with ablation and 0% with resection. Median survival was 6 months with no treatment, 27 months with ablation (P <.001), and 35 months with resection (P <.001). Patients who underwent liver transplantation had the longest median survival (53 months). A multivariate analysis suggested that treatment modality (ablation or resection; P <.001) and Child-Pugh classification (P <.01) were the most important factors predicting outcome.

Conclusions: This study suggests that treatment of hepatocellular carcinoma requires multidisciplinary expertise and that ablation and operation can be performed safely. Outcome is influenced most by treatment modality and Child-Pugh classification. Patients in Child-Pugh classes A and B should be treated with ablation, surgical resection, or liver transplantation.
