RESUMEN

Results of liver transplantation in the treatment of cholangiocarcinoma have been poor as a result of the high incidence of locoregional dissemination and tumor recurrence. This study evaluates the effect of neoadjuvant chemoradiation therapy combined with orthotopic liver transplantation in a carefully selected group of patients with hilar cholangiocarcinoma. Seventeen patients were included in the study. The neoadjuvant protocol included 6,000 cgy biliary brachy-therapy delivered through percutaneous transhepatic catheters and intravenous infusion of 5-fluorouracil (300mg/m2/day) until transplantation. Five of the 17 patients demonstrated tumor progression precluding transplantation. One patient died of sepsis on the waiting list. Eleven patients underwent liver transplantation, a median of 3.4 months (range = 1-26 months) after diagnosis. Five of the 11 (45%) are alive without evidence of tumor recurrence with a median follow up of 7.5 years (range = 2.8-14.5 years). Six deaths occurred in the transplanted patients. Tumor recurrence was responsible for two deaths at 10 and 18months, respectively, after transplantation. Three mortalities resulted from bacterial or fungal peritonitis and sepsis. One patient underwent re-transplantation for chronic rejection and died from graft failure resulting from hepatic artery thrombosis 16 months after diagnosis without evidence of tumor recurrence. Complications of transhepatic catheter placement included bile duct perforation (n = 4) and biliary-portal vein fistula (n = 1). All these patients died of tumor recurrence or sepsis. Cholangiocarcinoma should not be considered an absolute exclusion criteria for orthotopic liver transplantation. Long-term, tumor-free survival was achieved in 45% of the transplanted patients. Complications of biliary catheter placement for brachytherapy were associated with poor outcome.

RESUMEN

Decompensated liver disease associated with chronic hepatitis C virus (HCV) infection is the most common indication for liver transplantation. It was shown previously that greater pretransplantation HCV titers are associated with relatively poor patient and graft survival. The tolerability and efficacy of antiviral therapy in patients with decompensated liver disease are not known. We conducted a pilot study to determine the likely tolerability and efficacy of pretransplantation antiviral therapy with interferon alfa-2b, with or without ribavirin. HCV RNA-positive patients at or near the top of their respective waiting lists were randomly assigned to one of three treatment regimens until the time of liver transplantation: (1) group A, interferon alfa-2b, 1 x 10(6) U/d; (2) group B, interferon alfa-2b, 3 x 10(6) U three times weekly; or (3) group C, interferon alfa-2b, 1 x 10(6) U/d, plus ribavirin, 400 mg twice daily. Less than half the patients screened met entry criteria, with thrombocytopenia and leukopenia the most common reasons for exclusion. Fifteen patients were administered antiviral therapy; three patients in group A and six patients each in groups B and C. Loss of detectable HCV RNA was seen in 33% of patients, whereas 55% had a decrease in viral titers on therapy. Twenty-three adverse events occurred, including 20 serious adverse events. Thrombocytopenia was the most common adverse event. Two infectious complications occurred; one of these had a fatal outcome. We conclude that although pretransplantation antiviral therapy may reduce HCV titers in a minority of patients who meet treatment initiation criteria, adverse events associated with therapy are frequent and often severe in patients with Child's class B and C cirrhosis.
