Experience with 30 hepatic resections for primary malignant neoplasms is reported, 28 of the lesions being hepatocellular or cholangiolar carcinomas. None was associated with hepatic cirrhosis, since carcinomas associated with cirrhosis were invariably unresectable. More than half of the liver required resection in 23 instances. In 21, complications were absent or minor. Although survival data were satisfying (six of 13 patients eligible for five-year follow-up lived for five years), only four of the 13 who lived for five years are still alive. The operation is recommended as a palliative procedure.
