Liver cell dysplasia in normal, cirrhotic, and hepatocellular carcinoma patients.

An assessment was made of the frequency of liver cell dysplasia and the mean age of each group in 56 normal, 13 cirrhotic, and 50 hepatocellular carcinoma (HCC) patients, 40 with cirrhosis, from southern Africa. Dysplasia increased from 7.1% in normal subjects to 38.5% in cirrhotic, 40% in noncirrhotic HCC, and 52.5% in cirrhotic HCC patients, three statistically similar frequencies. Average patient ages were as follows: patients with normal livers, 37.3 years; with cirrhosis, 42.4 years; with noncirrhotic HCC, 36.5 years; and with cirrhotic HCC, 34 years, the mean age with dysplasia being lower than that of the whole group. With no increase in frequency of dysplasia from cirrhosis to HCC with cirrhosis, with a similar high frequency in HCC without cirrhosis, and with a mean age of all HCC patients 8 years less than that of cirrhotics and 3 years less than normals, chronologic evolutionary progression from cirrhosis to dysplasia to HCC in southern Africa cannot be demonstrated.
