Primary carcinoma of the liver in Alberta.

A survey was made to determine the incidence and to elucidate the manifestations of primary carcinoma of the liver in Alberta. The findings were compared with other reported series. Ninety-six cases were identified: 69 hepatomas, 25 cholangiomas and two cholangiohepatomas. Seventy-four of the patients were male and 22 were female, a male preponderance of greater than 3:1. Ages ranged from 7 days to 92 years, but the majority of the patients (58%) were in the seventh and eighth decades. The incidence of associated cirrhosis (38.5%) was lower than that noted in most series.Hepatomegaly, abdominal pain, weight loss and ascites were the outstanding clinical features. Gastrointestinal hemorrhage was frequent and second only to hepatic failure as the immediate cause of death. An abdominal mass and pleural effusion occurred in higher frequency than that cited in the literature. Associated disorders included peptic ulceration and cholelithiasis.Surgical biopsy was superior to needle biopsy in establishing the diagnosis. Laboratory tests and routine radiographs may be of diagnostic aid.
