Nevertheless, HLA-G expression was not related to other clinical parameters, such as age (HR = 0.95, 95% CI = 0.77–1.16, P = 0.593), sex (HR = 0.89, 95% CI = 0.76–1.04, P = 0.136), tumor type (HR = 1.18, 95% CI = 0.84–1.65, P = 0.340), tumor differentiation (HR = 0.71, 95% CI = 0.36–1.40, P = 0.320), TNM stage (HR = 1.05, 95% CI = 0.74–1.49, P = 0.798) or distant metastasis (HR = 1.42, 95% CI = 0.97–2.09, P = 0.072). This evidence concerns the gene HLA-G and neoplasm.
