Nolatrexed Dihydrochloride Compared With Doxorubicin in Treating Patients With Recurrent or Unresectable Liver Cancer

DISEASE CHARACTERISTICS:

• Histologically or cytologically proven or presumptive diagnosis of hepatocellular carcinoma

  • Presumptive diagnosis based on rising alpha-fetoprotein (AFP) levels over 2 assessments, CT scan or MRI of liver, spiral CT scan of portal/splenic vein, and biopsy evidence of cirrhosis
  • Unresectable or recurrent disease after prior surgical resection or embolization therapy
• Fibrolamellar histology allowed if considered surgically unresectable based on tumor size, extrahepatic involvement, or multiple lobe involvement
• CLIP (Cancer of the Liver Italian Program) score less than 4
• Concurrent assignment to a transplantation list allowed
