Experiences in liver transplantation for hepatocellular carcinoma.
Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Beside surgical resection, orthotopic liver transplantation (OLT) is not only effective but also the only potentially curable treatment in selected cases of small tumors. We report our experience in 11 male patients transplanted for HCC from August 1998 to July 2002. Selection criteria for OLT were unresectability of the hepatic tumor and severity of the underlying liver disease. The tumor diagnosis was confirmed by histology, imaging techniques, and tumor markers. All patients received an orthotopic liver allograft using a modified piggyback technique. Six of the 11 patients are alive; one died due to acute rejection and four died from recurrent disease. In all four patients with recurrent disease, vascular invasion was shown histologically, whereas only one patient without evidence of recurrence showed vascular invasion. To prevent recurrence after OLT the immunosuppressive regime was adjusted to the underlying disease by early cessation of prednisolone and reduction in the long-term exposure to immunosuppressive drugs. Patients were screened for recurrence by ultrasound and computed tomography. Recurrent HCC were treated symptomatically. OLT is an effective treatment for subgroups of patients with HCC. It might be possible to downstage the liver tumor by chemoembolization and/or radiofrequency ablation and allow the patients to wait for a suitable donor. After OLT the early withdrawal of prednisolone and the reduction of other immunosuppression is feasible. In conclusion, OLT can be a potentially curative therapy for HCC.
