Poor OS was observed for tumor size >2 cm compared to tumor size ≤2 cm (91% vs. 96%; 95% CI, 86-96 vs 93-99; p = 0.011), high (G3) compared to low (G1-2) histological grade (90% vs. 98%; 95% CI, 86-95 vs 95-100; p = 0.002), and high compared to low Ki67 expression (90% vs. 99; 95% CI, 86-95 vs 97-100; p = 0.0004). Here, MKI67 is linked to neoplasm.
