The diagnosis of HCC was confirmed by two dynamic imaging techniques (three-phase CT, NMR or arteriography) in 54 (41.5%) cases, by one dynamic image in 13 (10%), one dynamic image + alphafetoprotein (AFP) in 28 (21.5%), and by histology in 31 (23.9%), and in four cases (3.1%) HCC was an incidental finding in the explant. This evidence concerns the gene AFP and hepatocellular carcinoma.
