Furthermore, the BMI1-positive tumour group (Group III) showed significantly shorter DFS and OS times compared with the BMI1-negative tumour group alone (Group II: Figure 2; mean DFS time 39.9 ± 8.6 months, 95% CI 23.0–56.8 months, P = 0.045, Figure 3; mean OS times 53.1 ± 7.9 months, 95% CI 37.5–68.7 months, P = 0.006). Here, BMI1 is linked to neoplasm.
