Interestingly, as HCC developed and its aggressiveness increased, the AFP value tended to increase (median: NC of 3.80, LC of 14.32, stage I of 14.88, stage II of 39.80, stage III of 100.12, stage IV of 179.21), while the PP value tended to decrease a little (median: NC of 0.246, LC of 0.976, stage I of 0.780, stage II of 0.679, stage III of 0.643, stage IV of 0.615). Here, AFP is linked to hepatocellular carcinoma.
