HLA-F and neoplasm: Univariate and multivariate Cox proportional regression analyses showed that HLA-F expression (hazard ratio: 3.87; 95% confidence interval (CI): 1.29–11.58; p = 0.016) and tumour stage (hazard ratio: 4.31; 95% CI: 1.01–18.46; p = 0.049) were independent factors for LRFS (Table 2, Figure 2(a)).
