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

Figure 2 Overall survival curves for patients with expansive tumor growth and invasive tumor growth. A: No significant difference in survival was observed between patients with a single tumor and patients with multiple tumors. Moreover, no significant difference in survival was observed among patients with satellite nodules, patients with nodule fusion and patients with tumor invasion of adjacent organs; B: Based on the data, patients were divided to two groups: expansive tumor growth (single tumor and multiple tumors) and invasive tumor growth (satellite nodules, nodule fusion and tumors with direct invasion of adjacent organs). The overall survival was 57.398 ± 4.873 mo for patients with expansive tumor growth, while it was 27.796 ± 3.730 mo for patients with invasive tumor growth (P < 0.001).
