Current status of liver transplantation for hepatocellular cancer.
The incidence of hepatocellular cancer is increasing in the United States and is one of the most common cancers worldwide. Traditionally, the gold standard treatment for hepatocellular cancer has been surgical resection, but most patients were not suitable candidates due to advanced disease. Other treatments include locally ablative techniques (cryosurgery, radiofrequency ablation and various injection therapies), chemotherapeutic options and rarely, radiation therapies. In the 1980s, liver transplant emerged as the treatment of choice for end-stage liver disease and also became an option for patients with hepatocellular cancer. When comparing liver transplant with resection in retrospective studies, liver transplant patients had better survival and reduced recurrence. However, not all patients with hepatocellular cancer will be candidates for liver transplant. Size, stage, and histological grade of tumor all affect prognosis after transplant. Use of chemotherapeutic treatments and locally ablative techniques may be beneficial prior to liver transplant, but larger controlled studies are needed. Liver transplant is the most effective treatment for hepatocellular cancer in the subgroup of smaller tumors, but ultimately we are limited by the number of available donors. Future goals in this area include increasing the donor pool and determining optimal management to allow patients to wait for an appropriate donor.
