Overall survival (OS) by pathological stage, pleural invasion, and lymphovascular invasion. A, The 5-year OS was the worst for patients with stage III disease, followed by patients with stage II and stage I disease (40%, 51%, and 67%, respectively; p < 0.001). (B) The 5-year OS of patients with pleural invasion was significantly worse (n = 80; 42%) than those without pleural invasion (n = 405; 62%; p = 0.002). (C) The 5-year OS of patients with lymphovascular invasion was significantly worse (n = 332; 53%) than those without lymphovascular invasion (n = 153; 71%; p = 0.031).

5. FIGURE 4
Overall survival (OS) by tumor budding and single cell invasion. A, The 5-year OS of patients with high grade (≥10 buds/one high-power fields [HPF]) for maximum budding was significantly worse (n = 76; 39%) than those with low grade (<10 buds/one HPF; n = 409; 62%; p < 0.001). (B) The 5-year OS of patients with high grade (greater than or equal to eight buds/10 HPFs) for total tumor budding was significantly worse (n = 181; 46%) than those with low grade (less than eight buds/10 HPFs; n = 304; 67%; p = 0.007). (C) The 5-year OS of patients with single cell invasion in entire tumor was significantly worse (n = 197; 47%) than those without single cell invasion (n = 288; 67%; p = 0.002). (D) The 5-year OS of patients with single cell invasion in tumor edge was significantly worse (n = 134; 42%) than those without single cell invasion (n = 351; 65%; p = 0.001).

Overall survival (OS) by nuclear diameter. The 5-year OS of patients with large nuclei (greater than four small lymphocytes) was significantly worse (n = 153; 50%) than those with small nuclei (n = 332; 63%; p = 0.011).
