CDKN2A and cancer: Compared with HPV-/p16- cancers, patients with HPV+/p16+ cancers had significant improved DFS/DSS/RFS/PFS (HR = 0.23, 95% CI: 0.14–0.36), patients with HPV+/p16- cancers had no significant improved DFS/DSS/RFS/PFS (HR=0.63, 95% CI: 0.32–1.24), and patients with HPV-/p16+ cancers had no significant improved DFS/DSS/RFS/PFS (HR = 0.88, 95% CI: 0.45–1.69) (Figure 3).
