The in vitro uptake of bromodeoxyuridine (BrdU) by hepatocellular carcinoma (HCC) cells was studied in 30 hepatectomized patients. Labeling of the nuclei by BrdU expressed as labeling index (LI) was 5.6 ± 3.2% (mean ± standard deviation), with a considerable variation from case to case. The mean LI in Grade III to IV cancers (less differentiated, by Edmondson and Steiner's classification, 11.1 ± 2.1%) was significantly larger ( P < 0.001) than that in Grade I to II cancers (more differentiated, 4.5 ± 2.0%). Capsule formation was found in all 17 patients except one (94%) with a low DNA synthetic HCC (LI < 6.0%) compared with seven of 13 (54%) with a high DNA synthetic HCC (LI ± 6.0%, P < 0.02). The 2‐year survival rate after surgery was significantly higher ( P < 0.02), and intrahepatic metastasis was significantly less ( P < 0.05) in the former group than in the latter. The BrdU LI of HCC tumors showed a strong correlation with histopathologic findings and the biologic behavior of HCC.
