The Kaplan–Meier survival curve (Figure 3) demonstrated that patients with positive CXCL8 staining in this tumour infiltrate had a significantly improved RFS (median survival not reached) compared with patients with negative staining (median survival 69 months; 95% CI: 37.7–100.3, P<0.001 log-rank test). Here, CXCL8 is linked to neoplasm.
