Our results have shown no statistically significant associations between TIGIT expression with tumor size and tumor differentiation (HR = 2.84, 95% CI: 0.61–13.29, p-value = 0.18, and HR = 0.89, 95% CI: 0.36–2.24, p-value = 0.81, respectively) (Figure 2). This evidence concerns the gene TIGIT and neoplasm.
