Hepatocyte proliferative activity is elevated in cirrhotic patients who develop hepatocellular carcinoma (HCC) and decreased in alcohol-induced hepatitis patients with poor outcome. Hepatocyte proliferative activity has not been evaluated in an unselected population of cirrhotic patients regarding the severity of the disease. Forty-six cirrhotic patients (21 alcoholic, 20 viral, and 5 other) were prospectively analyzed by proliferating cell nuclear antigen (PCNA) immunostaining on methanol-fixed, paraffin-embedded liver biopsy specimens. In these conditions, the PCNA-labeling index (PCNA-LI) measures the number of cells in the S-phase and assesses tissue proliferation. The median value of the PCNA-LI for all samples was 4.3% (range, 0%-20.2%). It declined with worsening Child-Pugh score: 9.15% (range, 3.3%-20.2%), 5.3% (range, 1.2%-18%), and 2.4% (range, 0%-4.4%) in Child classes A, B, and C, respectively (P < .05). Using the best cutoff PCNA-LI value to divide cirrhosis into slowly and rapidly proliferating tissue subsets, the PCNA index was independently associated with serum albumin. The probability of survival in patients with a high PCNA-LI (> 4.4%) was significantly higher than in those with a lower PCNA-LI (0.93 vs. 0.53, at a median follow-up of 153 days; P = .01). In all 6 patients undergoing placement of a transjugular intrahepatic portosystemic shunt (TIPS), the PCNA-LI decreased after the procedure. This early impairment of hepatocyte proliferative activity after ...
