Proposal of new classification for postoperative patients with hepatocellular carcinoma based on tumor growth characteristics

Figure 3 Overall survival curves for patients with disseminative growth. A: No significant difference in survival was observed between patients with vascular involvement of tumor and patients with regional lymph node metastasis. The overall survival (OS) of patients with tumors that lacked vascular and regional lymph node involvement was longer than those of other groups, while the OS of patients with distant metastasis was shorter than those of other groups; B: Based on these data, patients were divided into three groups: tumors without vascular and regional lymph node involvement, tumors with vascular and/or regional lymph node involvement and distant metastasis.
