Figure 4 New classification for hepatocellular carcinoma. A: Overall survival (OS) curves for patients based on tumor-node-metastasis system classification; B: OS curves for patients with expansive growth, invasive growth and disseminative growth; C: OS curves for patients based on Expansive-Invasive-Disseminative growth (EID) staging classification; D: OS curves for patients with different levels of alpha-fetoprotein (AFP); E: OS curves for patients based on EID staging classification and AFP; F: Overall survival curves for patients combined EID staging classification and AFP.
