NEIL3 and neoplasm: These factors were then selected for DFS multivariate analysis, which revealed that NEIL3 expression (HR 1.947; 95% CI 1.233–3.074; P=0.004), TNM stage (HR 3.131; 95% CI 1.165–8.416; P=0.024), and tumor differentiation (HR 1.691; 95% CI 1.089–2.625; P=0.019) were significant factors of DFS (Table 3).
